Affective temperaments in tango dancers. J Affect Disord 2015; 173:27-30. [PMID: 25462392 DOI: 10.1016/j.jad.2014.10.018] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2014] [Revised: 10/08/2014] [Accepted: 10/09/2014] [Indexed: 10/24/2022]
Abstract
BACKGROUND Links between affective temperaments and folk culture have been infrequently explored systematically. Creativity and personality and temperament studies, conversely, have reported several associations. Tango is one of the most typical Argentinean folk dance-musical repertoires. The main purpose of this study is to compare affective temperaments between Argentinean professional tango dancers and the general population. METHODS TEMPS-A was administered to a sample of 63 professional tango dancers and 63 comparison subjects from the general population who did not practice tango. Subscale median scores and total median scores with non-parametric statistics were analyzed. RESULTS Median scores on hyperthymic subscale (p ≤ 0.001), irritable subscale (p=0.05) and total median score were significantly higher among tango dancers compared to controls (p ≤ 0.001). LIMITATIONS Self-report measures were used. A larger sample size would have provided greater statistical power for data analysis. Besides, the naturalistic study design did not allow controlling for other clinical variables and limited the generalization of results to broader populations. CONCLUSIONS Our data adds new evidence for the hypothesis that artistic performance is related to one's temperament. Tango passionata, which has both melancholic and vigorous (including "upbeat") features, seems to impart tango dancers' hyperthymic and irritable temperament features. Our study supports the increasing literature on the validity of utilizing temperament as a sub-affective traits in relation to artistic creativity and performing arts.

Psychometric properties of the Hong Kong Chinese (Cantonese) TEMPS-A in medical students. J Affect Disord 2015; 170:23-9. [PMID: 25218733 DOI: 10.1016/j.jad.2014.08.026] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2014] [Revised: 07/26/2014] [Accepted: 08/06/2014] [Indexed: 12/23/2022]
Abstract
BACKGROUND The self-rated auto-questionnaire, the Temperament Scale of Memphis, Pisa, Paris and San Diego (TEMPS-A) is the latest development in the study of temperamental attributes. It has been used and validated in different cultures and countries. The current study aims at validating the Chinese (Cantonese) version of the TEMPS-A and comparing the psychometric properties of the long and short forms of the translated scale. METHODS The Chinese (Cantonese) version of TEMPS-A was prepared with the standard translation and back-translation method, and approved by the original authors (HSA & KKA). It was administered to medical students of the two local universities, and results were analyzed. RESULTS 613 valid questionnaires were returned. The Cronbach-Alpha coefficients for the depressive, cyclothymic, hyperthymic, irritable and anxious temperament subscales were 0.63, 0.82, 0.78, 0.80, and 0.84, respectively. The strongest correlation was observed between the cyclothymic and irritable temperaments (R=0.600). Factor analysis yielded one large composite (depressive and anxious) and four homogenous factors, cyclothymic, anxious, hyperthymic and irritable. A newly reconstituted 43-item short form, based on methods suggested by the original authors yielded similar factor structure. LIMITATIONS The narrow age range of subjects somewhat limits generalization of the results. However, external and concurrent validations against other validated scales have been demonstrated for the original English versions as well as against the most commonly used languages of the world; furthermore, such validation has also been demonstrated for Chinese (Mandarin). CONCLUSIONS The Chinese (Cantonese) version of TEMPS-A and the reconstituted 43-item short form were found to have good internal consistency and factor structures comparable to those of other languages from diverse cultures across the planet. We propose that the Cantonese TEMPS-A is a useful tool for local use.

Temperamental dimensions of the TEMPS-A in male and female subjects engaging in extreme or/and high risk sports. J Affect Disord 2015; 170:66-70. [PMID: 25233241 DOI: 10.1016/j.jad.2014.08.036] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2014] [Revised: 08/23/2014] [Accepted: 08/25/2014] [Indexed: 01/27/2023]
Abstract
OBJECTIVES We investigated temperamental dimensions of the Temperament Evaluation of Memphis, Pisa and San Diego Autoquestionnaire (TEMPS-A) as well as bipolarity features in male and female subjects engaging in extreme or/and high risk sports. METHODS The web-based case-control study was performed in 480 subjects engaging in extreme or/and high risk sports (255 male, 225 female) aged 26 ± 6 years and in 235 age- and sex-matched healthy controls subjects (107 male, 128 female), aged 28 + 9 years. The TEMPS-A questionnaire, 110 questions version, has been used, evaluating five temperament domains: depressive, cyclothymic, hyperthymic, irritable and anxious. The Mood Disorder Questionnaire (MDQ) was employed for the assessment of bipolarity. RESULTS Both male and female athletes had significantly higher scores of hyperthymic temperaments compared with control male and female subjects who had declared themselves as not involved into the activities of extreme or/and high risk sports. In addition, compared with controls, male sportsmen had lower scores of depressive and anxious temperaments, and female athletes had higher scores of cyclothymic and irritable temperaments. Both male and female athletes obtained significantly higher scores of bipolarity as measured by the MDQ, than control men and women. LIMITATIONS Web-based study involving a risk of selection and recall bias, problematic homogeneity of the experimental group. CONCLUSIONS Subjects engaged into extreme or/and high risk sports have significantly higher scores of hyperthymic temperament, measured by the TEMPS-A and present sex-specific features of other temperaments. Such subjects obtain also greater bipolarity scores as measured by the MDQ.

Validation of the Chinese Version of the Short TEMPS-A and its application in patients with mood disorders. J Affect Disord 2015; 170:178-84. [PMID: 25243747 DOI: 10.1016/j.jad.2014.08.041] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/13/2014] [Revised: 08/08/2014] [Accepted: 08/14/2014] [Indexed: 12/17/2022]
Abstract
BACKGROUND The short version of Temperament Evaluation of the Memphis, Pisa, Paris, and San Diego-Auto-questionnaire (TEMPS-A) is a useful instrument to measure affective temperaments. Aims of the present study are to validate the Chinese Version of the Short TEMPS-A, and to explore whether it could be useful to distinguish patients with mood disorders from healthy controls or differentiate patients with bipolar disorder (BPD) from those with major depressive disorder (MDD) in Chinese population. METHODS A sample of 715 participants, including 387 patients with MDD, 143 with BPD and 185 healthy controls, was recruited. All participants completed The Chinese Version of the Short TEMPS-A. Standard psychometric tests of reliability and validation were performed. ANOVA, non-parameter test and Multiple Logistic Regression were used to test the association between TEMPS-A scores and mood disorders. RESULTS The originally proposed five factors of the Chinese Version of the Short TEMPS-A were upheld. The Chronbach-Alpha coefficients of it varied from 0.70 to 0.89 and test-retest Spearman׳s Correlation Coefficients varied from 0.52 to 0.85. Significant differences were found across the three groups on all five TEMPS-A subscales (P<0.001). Multiple Logistic Regression showed that hyperthymic temperament distinguished patients with BPD from those with MDD (OR 1.28, 95% CI 1.14-1.45, P<0.001) after controlling for age, gender and the severity of depression. LIMITATIONS The cross-sectional self-report design, unbalanced demographic characteristics and undifferentiated subtypes of bipolar disorders might limit the generalizability of the results. CONCLUSION The Chinese Version of the Short TEMPS-A shows good reliability and validity. It might be used as a screening tool in the general population to identify the vulnerability for developing a mood disorder and the potential risk for bipolar disorder among those who only have depressive symptoms.

Temperamental dimensions of the TEMPS-A in females with co-morbid bipolar disorder and bulimia. J Affect Disord 2014; 164:90-3. [PMID: 24856559 DOI: 10.1016/j.jad.2014.04.016] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/28/2014] [Revised: 04/09/2014] [Accepted: 04/10/2014] [Indexed: 10/25/2022]
Abstract
OBJECTIVES We investigated the effect of co-morbid bipolar disorder and bulimia on temperamental dimensions measured by TEMPS-A, relative to "pure" bulimia and "pure" bipolar disorder, in female patients. METHODS The study was performed on 47 patients with bipolar disorder (BD) with a mean age of 36±10 years, 96 patients with bulimia or bulimic type of anorexia, mean age 26±9 years and 50 control healthy females (HC), mean age 29±6 years. Among bulimic patients, a group of 68 subjects with co-morbid bulimia with bipolarity (BD+B) was identified, based on positive score of the Mood Disorder Questionnaire (MDQ). The TEMPS-A questionnaire, 110 questions version, has been used, evaluating five temperament domains: depressive, cyclothymic, hyperthymic, irritable and anxious. Parametric analysis was performed for 4 groups (BD, "pure" bulimia (PB), BD+B and HC), with 28 subjects randomly chosen from each group, using analysis of variance and cluster analysis. RESULTS All clinical groups significantly differed from control group by having higher scores of depressive, cyclothymic, irritable and anxious temperaments and lower of hyperthymic one. Among patients, significantly higher scores of cyclothymic and irritable temperaments were found in BD+B compared to both PB and BD. These differences were also reflected in cluster analysis, where two clusters were identified. LIMITATIONS Bipolarity in bulimic patients assessed only by the MDQ. CONCLUSIONS These results show that co-morbid bulimia and bipolar disorder is characterized by extreme dimensions of both cyclothymic and irritable temperaments, significantly higher than each single diagnosis. Possible clinical implications of such fact are discussed.

Towards validation of the short TEMPS-A in non-clinical adult population in Serbia. J Affect Disord 2014; 164:43-9. [PMID: 24856552 DOI: 10.1016/j.jad.2014.04.005] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/11/2014] [Revised: 04/02/2014] [Accepted: 04/02/2014] [Indexed: 11/18/2022]
Abstract
BACKGROUND AND AIMS This study represents the standardisation of the Serbian version of the TEMPS-A scale on non-clinical adult population, as well as external validation with TCI-R scale of temperaments which has already been evaluated on Serbian population. METHODS The TEMPS-A has been administered to 570 healthy adults without histories of mental disorders, 47% male, 53% female, aged between 20 and 76 (M=35.55; SD=14.14). In line with the state census data, the sampling was partially stratified according to gender, age categories, education and regional area of the participants. RESULTS In contrast to many other studies, six factors were extracted herein, including 41 items with loadings above .50, explaining 44.40% of the total variance. The internal consistency of the scale was α=.83, and the average test-retest coefficient (rho=.82) indicates a stable reliability. The highest positive correlations were obtained between the depressive and cyclothymic scales, depressive and anxious scales, and cyclothymic with anxious scales. The highest values were detected on hyperthymic and the lowest on depressive temperament. The highest positive correlations were reported between harm avoidance (measured by the TCI-R) and depressive, anxious, cyclothymic temperament, and between novelty seeking and hyperthymic temperament. The highest negative correlation was detected between harm avoidance and hyperthymic. Finally, females scored higher on depressive, cyclothymic and anxious, while males scored higher on hyperthymic temperament. LIMITATIONS The participants׳ educational background was slightly higher than that of the general population of Serbia. Since the scale is aimed at its administration in clinical population as well, it is necessary that its structure and validity be also tested on specific clinical subpopulations in the future. CONCLUSIONS The current study is significant in having confirmed that the TEMPS-A can be reliably and validly used in identifying affective temperaments in the adult nonclinical population in Serbia, which provides the basis and norms for future comparisons with clinical subpopulations.

Association of affective temperaments measured by TEMPS-a with cognitive deficits in patients with bipolar disorder. J Affect Disord 2014; 161:109-15. [PMID: 24751317 DOI: 10.1016/j.jad.2014.03.005] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2013] [Revised: 03/06/2014] [Accepted: 03/06/2014] [Indexed: 12/27/2022]
Abstract
BACKGROUND Affective temperaments such as cyclothymia, which may be the fundamental substrates for bipolar disorder and bipolar II in particular, have been reported to be associated with abnormalities in the regions that are related to cognitive deficits in bipolar disorder. However, few studies have examined the effects of affective temperaments on neuropsychological performance in individuals with bipolar disorder. METHOD In a six-week prospective study, we administered Chinese version of TEMPS-A (Temperament Evaluation of Memphis, Pisa, San Diego-Autoquestionnair) to 93 patients with bipolar I depression, 135 patients with bipolar II depression, and 101 healthy controls. Cognitive function was assessed with a battery of neuropsychological tasks, including attention, processing speed, set shifting, planning, verbal working memory, verbal fluency, and visual spatial memory. Mixed-effects statistical models were used to assess the effects of affective temperaments on cognitive function. RESULTS Bipolar patients with hyperthymic temperament showed greater cognitive deficits in set shifting (p=0.05) and verbal working memory (p=0.026) than did bipolar patients with non-predominant temperaments (predominant temperament was defined as one standard deviation above the mean). The differences in estimated marginal means were -0.624 (95% CI, -1.25 to 0) and -0.429 (95% CI, -0.81 to -0.05), respectively. Significant temperament X bipolar subtype interaction effects were observed for set shifting (Wald X(2)=18.161, p<0.001), planning (Wald X(2)=7.906, p=0.048), and visual spatial memory (Wald X(2)=16.418, p=0.001). LIMITATION The anxious temperament was not evaluated. CONCLUSION Our data suggest that hyperthymic temperament may be associated with cognitive deficits in some specific domains in bipolar disorder; and that the effect of temperaments may be different across subtypes of bipolar disorder.

Lifetime mania is related to post-traumatic stress symptoms in high school students exposed to the 2009 L'Aquila earthquake. Compr Psychiatry 2014; 55:357-62. [PMID: 24269194 DOI: 10.1016/j.comppsych.2013.08.017] [Citation(s) in RCA: 40] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2013] [Revised: 07/18/2013] [Accepted: 08/04/2013] [Indexed: 12/28/2022] Open
Abstract
BACKGROUND Bipolar patients seem to be at high risk of trauma exposure and, when exposed, of PTSD. When comorbid, PTSD has shown a negative impact on the course of the bipolar illness. Conversely, a correlation between even manic symptoms and an increased risk for suicide has also been reported in PTSD patients. The aim of this study was to investigate the relationships between lifetime mood spectrum symptoms and PTSD in a sample of earthquake survivors. METHODS A total of 475 young adults who survived the L'Aquila 2009 earthquake, 21months earlier, were assessed by the Moods Spectrum-Self Report (MOODS-SR) and the Trauma and Loss Spectrum Self Report (TALS-SR). RESULTS Significantly higher MOODS-SR and TALS-SR domain scores were found in PTSD survivors compared to those without. The mood depressive (O.R.=1.17, 95% CI: 1.10-1.25), cognition depressive (O.R.=1.07, 95% CI: 1.01-1.14) and energy manic (O.R.=1.13, 95% CI: 1.02-1.25) MOODS-SR domains were significantly associated with an increased likelihood of PTSD. CONCLUSIONS Our data corroborate the strong relationship between mood disorder and PTSD highlighting a relationship between lifetime depressive and manic symptoms and PTSD, with a particular impact of the latter on the number of traumatic exposures and maladaptive behaviors.

Post-traumatic stress disorder in DSM-5: estimates of prevalence and criteria comparison versus DSM-IV-TR in a non-clinical sample of earthquake survivors. J Affect Disord 2013; 151:843-8.

Abstract
BACKGROUND The latest edition of DSM (DSM-5) introduced important revisions to PTSD symptomatological criteria, such as a four-factor model and the inclusion of new symptoms. To date, only a few studies have investigated the impact that the proposed DSM-5 criteria will have on prevalence rates of PTSD. METHODS An overall sample of 512 adolescents who survived the L'Aquila 2009 earthquake and were previously investigated for the presence of full and partial PTSD, using DSM-IV-TR criteria, were reassessed according to DSM-5 criteria. All subjects completed the Trauma and Loss Spectrum-Self Report (TALS-SR). RESULTS A DSM-5 PTSD diagnosis emerged in 39.8% of subjects, with a significant difference between the two sexes (p<0.001), and an overall 87.1% consistency with DSM-IV-TR. Most of the inconsistent diagnoses that fulfilled DSM-IV-TR criteria but not DSM-5 criteria can be attributed to the subjects not fulfilling the new criterion C (active avoidance). Each DSM-5 symptom was more highly correlated with its corresponding symptom cluster than with other symptom clusters, but two of the new symptoms showed moderate to weak item-cluster correlations. Among DSM-5 PTSD cases: 7 (3.4%) endorsed symptom D3; 151 (74%) D4; 28 (13.7%) both D3 and D4; 75 (36.8%) E2. LIMITATIONS The use of a self-report instrument; no information on comorbidity; homogeneity of study sample; lack of assessment on functional impairment; the rates of DSM-IV-TR qualified PTSD in the sample was only 37.5%. CONCLUSIONS This study provides an inside look at the empirical performance of the DSM-5 PTSD criteria in a population exposed to a natural disaster, which suggests the need for replication in larger epidemiological samples.

TEMPS-A and long-term lithium response: positive correlation with hyperthymic temperament. J Affect Disord 2013; 145:187-9. [PMID: 22939170 DOI: 10.1016/j.jad.2012.07.028] [Citation(s) in RCA: 43] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2012] [Accepted: 07/21/2012] [Indexed: 11/18/2022]
Abstract
BACKGROUND Lithium is still regarded as a cornerstone for the long-term treatment of bipolar disorder. The best response to lithium is associated with clinical features of episodic clinical course, complete remission, bipolar family history and low psychiatric comorbidity. However, a specific personality profile for the best lithium response was not estimated so far. Such a possibility occurred with an advent of temperament scale for bipolar disorder and of an ability to quantitatively assess lithium prophylactic response. METHODS The study was performed on 71 patients with bipolar mood disorder (21 males, 50 females), aged 31-82 (59±12) years, which have been treated with lithium carbonate for at least 5 years (5-37 years, mean 15 years). In all patients, the assessment of five temperaments of TEMPS-A scale (depressive, cyclothymic, hyperthymic, irritable and anxious) was done, and correlated with the quality of lithium prophylaxis according to Alda scale. RESULTS The mean scores for five temperaments of TEMPS-A were not significantly different in male and female patients. The response to lithium correlated significantly positively with hyperthymic temperament score (r=0.31, p=0.009), and negatively with anxiety (r=-0.27, p=0.022), cyclothymic (r=-0.26, p=0.032), and depressive (r=-0.23, p=0.052) temperaments scores. LIMITATIONS Relatively small number of patients. CONCLUSIONS The main finding of the study is an association of lithium response with hyperthymic temperament. This positive correlation as well as other negative correlations between lithium response and TEMPS-A temperaments are discussed in view of clinical and genetic findings in bipolar patients.

Abstract
BACKGROUND Suicide is a major health problem accounting for up to 1.5 percent of all deaths worldwide and represents one of the most common causes of death in adolescents and young adults. A number of studies has been performed to establish risk factors for suicide in patients with psychiatric disorders including temperamental features. This study set out to assess the relationship between suicidal ideation and temperament in young adults. METHODS A cross-sectional sample of healthy college students (n=1381) was examined using a self-rating questionnaire. Suicidal ideation, social background, educational status, substance abuse, and affective temperament according to TEMPS-M were assessed. Predictors of lifetime suicidal ideation were examined in multivariate logistic regression analyses. RESULTS Suicidal ideation was reported by 12.5% of all subjects at some point in their life and was higher in nicotine dependents, youth with alcohol related problems and users of illicit substances as well as in youth with lower educational status. Lifetime suicidal ideation was associated with the anxious, depressive and cyclothymic temperament in both sexes and the irritable temperament in males. These results remained significant after adjustment for smoking status, frequency of alcohol consumption, drug experience and educational status in a multivariate logistic regression analysis. LIMITATIONS The use of self-rating instruments always reduces objectivity and introduces the possibility of misreporting. CONCLUSIONS Considering the fact that many subjects completing suicide have never been diagnosed with mental disorders it might be reasonable to include an investigation of temperament in screenings for risk of suicide. This might be especially useful for health care professionals without mental health care background.

Pain complaints in latino adults of mexican origin with and without major depressive episode: a cross-sectional study. PRIMARY CARE COMPANION TO THE JOURNAL OF CLINICAL PSYCHIATRY 2012; 10:191-6. [PMID: 18615171 DOI: 10.4088/pcc.v10n0303] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/19/2007] [Accepted: 11/26/2007] [Indexed: 01/01/2023]
Abstract
BACKGROUND The aim of this retrospective, cross-sectional study was to determine the prevalence of 5 pain complaints among Latino adults of Mexican origin meeting the criteria for major depressive episode (MDE). METHOD In a mental health clinic for the indigent, consecutively evaluated Latino adults of Mexican origin received structured diagnostic psychiatric interviews based on modules extracted from the Structured Clinical Interview for DSM-IV Axis I Disorders-Clinical Version. All were specifically asked whether they had experienced headache, backache, abdominal pain, myalgia, or arthralgia "in the last week." Patients meeting the criteria for MDE were compared to patients without MDE from the same clinic. Associations and statistical significance of the differences between groups were determined using logistic regression models. The data were collected between August 2003 and November 2004. RESULTS Two hundred ten patients had an MDE, and 35 individuals without an MDE comprised the comparison group. Eighty-eight percent of the patients with MDE versus 53% of the controls had at least 1 pain complaint (p < .0001). Patients with MDE were 8.3 times more likely to have 1 or more pain complaints than the comparison patients (p < .0001). The significant relationship between depression and pain applied when we examined those with ≥ 2, ≥ 3, and ≥ 4 pain complaints. Twenty-eight percent of the MDE subjects had all 5 pain complaints compared to 3% of subjects without MDE (p = .013). CONCLUSIONS The method of assessment of the presence of pain led to the detection of a remarkably high prevalence of pain complaints. The findings presented have important implications not only for the practice of those who are widely recognized as being primary care physicians but also for practitioners of all clinical disciplines.

Genome-wide association study of temperament in bipolar disorder reveals significant associations with three novel Loci. Biol Psychiatry 2012; 72:303-10.

Abstract
BACKGROUND The many attempts to identify genes for bipolar disorder (BD) have met with limited success, which has generally been attributed to genetic heterogeneity and small gene effects. However, it is also possible that the categorical phenotypes used in genetic studies of BD are not the most informative or biologically relevant. Although quantitative phenotypes provide an alternative to categorical phenotypes based on diagnosis, they have not been fully exploited in BD genetics due to the lack of accessible biological measures. We have explored aspects of temperament as quantitative phenotypes that might define subtypes of BD with different clinical features and courses of illness. Temperament is a heritable personality factor that establishes the baseline level of reactivity, mood, and energy of a person. METHODS We have performed a genome-wide association study with genotype data from the Bipolar Genome Study and 1263 bipolar subjects that had completed the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A). The TEMPS-A is designed to assess lifelong, milder aspects of bipolar symptomatology and defines five temperaments: hyperthymic, dysthymic, cyclothymic, irritable, and anxious. RESULTS The irritable temperament produced the most significant result with a genome-wide significant p value of 1.7 × 10(-8) on chromosome 1. The hyperthymic temperament produced additional genome-wide significant p values of 4.1 × 10(-8) and 2.1 × 10(-8) on chromosomes 12 and 22, respectively. CONCLUSIONS These results suggest that aspects of temperament might define subtypes of BD that are more clinically and genetically homogenous, which might aid in the identification of predisposing genetic variants.

[PMID: 23293608 PMCID: PMC3537190 DOI: 10.3389/fpsyt.2012.00111] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/25/2012] [Accepted: 12/12/2012] [Indexed: 12/26/2022] Open
Abstract
BACKGROUND Post-traumatic stress disorder (PTSD) represents one of the most frequently psychiatric sequelae to earthquake exposure. Increasing evidence suggests the onset of maladaptive behaviors among veterans and adolescents with PTSD, with specific gender differences emerging in the latter. Aims of the present study were to investigate the relationships between maladaptive behaviors and PTSD in earthquake survivors, besides the gender differences in the type and prevalence of maladaptive behaviors and their association with PTSD. METHODS 900 residents of the town of L'Aquila who experienced the earthquake of April 6th 2009 (Richter Magnitude 6.3) were assessed by means of the Trauma and Loss Spectrum-Self Report (TALS-SR). RESULTS Significantly higher maladaptive behavior prevalence rates were found among subjects with PTSD. A statistically significant association was found between male gender and the presence of at least one maladaptive behavior among PTSD survivors. Further, among survivors with PTSD significant correlations emerged between maladaptive coping and symptoms of re-experiencing, avoidance and numbing, and arousal in women, while only between maladaptive coping and avoidance and numbing in men. CONCLUSIONS Our results show high rates of maladaptive behaviors among earthquake survivors with PTSD suggesting a greater severity among men. Interestingly, post-traumatic stress symptomatology appears to be a better correlate of these behaviors among women than among men, suggesting the need for further studies based on a gender approach.

Creativity and affective temperaments in non-clinical professional artists: an empirical psychometric investigation. J Affect Disord 2011; 135:28-36. [PMID: 21820743 DOI: 10.1016/j.jad.2011.06.062] [Citation(s) in RCA: 41] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2011] [Revised: 06/29/2011] [Accepted: 06/30/2011] [Indexed: 11/28/2022]
Abstract
OBJECTIVE Manic-depression/bipolar disorder was linked to creativity, with affective temperaments allegedly favoring creative expression and achievement, but a few studies only empirically tested the link. METHODS 152 undergraduate students attending preparatory courses for creative artistic professions and 152 students in areas expected to lead to a profession mostly requiring the application of the learned rules were invited to fill in the TEMPS-A (Temperament Evaluation of the Memphis, Pisa, Paris and San Diego - Autoquestionnaire), the General Health Questionnaire (GHQ) and the Creative Achievement Questionnaire (CAQ). Latent class analysis (LCA) was used to investigate the links between creativity scores and measures of psychopathology. RESULTS Creative participants and controls did not differ in terms of sex (males=47%), age (24.5 years, SD=3.8), or socioeconomic status. Creative people scored higher than controls on the CAQ and on the cyclothymic, hyperthymic and irritable subscales of the TEMPS-A, but not on the GHQ. Greater involvement in creative activities rather than being a creative achiever best differentiated those into the "risk for bipolar spectrum" class from the other two classes extracted by the LCA from the TEMPS-A. LIMITATIONS The use of self-report measures to evaluate both creative involvement and the risk of psychopathology, and the exclusive focus on artistic creativity limit the generalizability of the findings. CONCLUSIONS This study confirms that the cyclothymic dimension of the bipolar spectrum is linked to creativity, and this link is likely to result from increased involvement into pleasurable activities, including creative ones.

From putative genes to temperament and culture: cultural characteristics of the distribution of dominant affective temperaments in national studies. J Affect Disord 2011; 131:45-51. [PMID: 21195481 DOI: 10.1016/j.jad.2010.12.003] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/06/2010] [Revised: 10/29/2010] [Accepted: 12/02/2010] [Indexed: 11/28/2022]
Abstract
BACKGROUND Affective temperaments may carry distinct evolutionary advantages both on the individual or a group level, so we can expect that in different cultural and national samples the frequency of dominant affective temperaments will show characteristic differences. The aim of the present study was to investigate the characteristics of distribution of dominant affective temperaments in different national studies of general non-clinical population. METHOD In our study we included six studies published in different countries around the world (Argentina, Germany, Hungary, Korea, Portugal, and Lebanon) which investigated a large sample of non-clinical population using TEMPS-A, and reported frequencies for dominant affective temperaments. The frequencies of dominant affective temperaments were compared using chi square tests. RESULTS We found a significant difference in the frequency of affective temperaments among the different national studies in case of the cyclothymic, hyperthymic and irritable temperaments. CONCLUSIONS We found important parallels between the frequency of affective temperaments and cultural dimensions described by Hofstede (Hofstede and Hofstede, 2005). The characteristics encompassed by the depressive temperament show considerable similarities with Hofstede's individualism-collectivism dimension, while those of the hyperthymic temperament seem to be similar to uncertainty avoidance, and the irritable temperament shows similarities with Hofstede's power distance. Furthermore, the relative frequency of these dominant temperaments in case of the different national samples paralleled the relative scores of these countries on the corresponding cultural scales. Our results indicate an important relationship between affective temperaments and cultural dimensions, which suggests that these phenomena may be the manifestations of the same genetically determined predispositions in different forms. LIMITATION We included a study by Erfurth et al. (2005), in which affective temperaments were evaluated using the TEMPS-M. Also, in the Korean study the Korean version of the TEMPS-A was not validated.

Confirmation of the factorial structure of temperamental autoquestionnaire TEMPS-A in non-clinical young adults and relation to current state of anxiety, depression and to schizotypal traits. J Affect Disord 2011; 131:37-44. [PMID: 21333358 DOI: 10.1016/j.jad.2011.01.008] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2010] [Accepted: 01/13/2011] [Indexed: 12/13/2022]
Abstract
BACKGROUND The 39-item TEMPS-A self-rated questionnaire assesses affective temperaments. We examined the factorial structure of its French version in a large sample of young adults and examined the relation to schizotypy, depression and anxiety. METHOD University students were enrolled during their mandatory preventive health visit in the University medical facility (n = 3807, 19.9 ± 2.5 y.o.). They answered to the 39-TEMPS-A questionnaire, the Schizotypal Personality Questionnaire (SPQ) and the Hospital Anxiety Depression Scale (HADS). We performed an exploratory Factorial Component Analysis (FCA) with varimax rotation of the 39-TEMPS-A in half of the sample, randomly selected, followed by a Confirmatory Factor Analysis (CFA) in the remaining subsample. TEMPS-A dimensions were correlated to HADS and SPQ sub-scores. RESULTS A five-factor structure was found by PCA and confirmed by the confirmatory analysis. The scale showed a good internal consistency (whole scale Cronbach's α: 0.83 and from 0.78 to 0.59 for Cyclothymic, Depressive, Irritable, Hyperthymic, Anxious subscales). Depressive and Anxious TEMPS-A subscales were moderately correlated to HADS Depression and Anxiety subscales (Spearman ρ = 0.37 to 0.33). Cyclothymic and Depressive TEMPS-A subscales were respectively correlated to SPQ Paranoid (ρ = 0.53) and Negative dimensions (ρ = 0.52). LIMITATION Representativity of the sample (higher education, response rate). CONCLUSION We confirmed the five factor structure of the 39-item TEMPS-A in a large non-clinical population of young adults and found consistent correlations with anxiety - depression state markers and schizotypal traits.

Temperament in Portuguese university students as measured by TEMPS-A: implications for professional choice. J Affect Disord 2010; 123:30-5. [PMID: 19910054 DOI: 10.1016/j.jad.2009.10.005] [Citation(s) in RCA: 12] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2009] [Revised: 10/08/2009] [Accepted: 10/08/2009] [Indexed: 12/01/2022]
Abstract
BACKGROUND The structure of temperament displays subaffective traits as attributes of adaptive value. There are few studies on how different professions compare on temperaments. Our aim was to examine the relationship between the choices of Portuguese students in their fields of study, and their respective temperaments. METHODS The sample included 1386 students from six different universities (law, engineering, arts, medicine, psychology, and nursing), of both genders (67% female), and ages between 17 and 58 (X + or - SD = 21 + or - 3.4). RESULTS Law and art students presented a cyclothymic or irritable temperament. Engineering students presented a hyperthymic temperament. Psychology and nursing students presented predominantly depressive and anxious temperaments. Medicine students were least extreme in temperament scores or frequencies. LIMITATIONS Nursing students came largely from one university located in a Portuguese city (northeast from Lisbon) which could be a potential limitation to be confirmed. CONCLUSIONS Distinct temperamental profiles of students enrolled in different professional fields could be identified in our sample taking into account the presence or absence of excessive temperaments. Future physicians did not present a predominant temperament, future lawyers and artists presented predominantly a cyclothymic or irritable temperament, future engineers presented a hyperthymic temperament and, future psychologists and nurses presented predominantly depressive and anxious temperaments.

Polish validation of the TEMPS-A: the profile of affective temperaments in a college student population. J Affect Disord 2010; 123:36-41. [PMID: 19880192 DOI: 10.1016/j.jad.2009.09.024] [Citation(s) in RCA: 38] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2008] [Revised: 09/30/2009] [Accepted: 09/30/2009] [Indexed: 11/18/2022]
Abstract
BACKGROUND AND AIMS The TEMPS-A scale is a self-evaluation measure to assess five affective temperaments: depressive, cyclothymic, hyperthymic, irritable and anxious. The scale has already been validated in over 10 languages. In this paper, the first report on the validation of the Polish version of TEMPS-A is presented. METHODS The TEMPS-A questionnaire version that includes 110 questions has been adapted following the translation-back translation methodology from English to Polish, checked by the originators of the five scales (H.S.A., K.K.A.). In the next step, the Polish version of TEMPS-A was administered to 521 Polish undergraduate students. Internal consistency of temperamental scales was measured with Cronbach-alpha coefficients. Correlation among the temperaments was examined using Pearson's bivariate correlation. Differences between sexes were tested with ANOVA. RESULTS The Cronbach-alpha and the Kuder-Richardson 20 reliability coefficients for the depressive, cyclothymic, hyperthymic, irritable and anxious temperaments were between 0.69 and 0.83. The percentage of subjects whose Z-scores were above 2 SD, was the highest among depressive (4%) and anxious (3.5%) temperaments, followed by the cyclothymic (2.9%), hyperthymic (1%), and irritable (0.6%). The strongest positive correlations between the temperamental scales were found between depressive and anxious, as well as between cyclothymic and irritable ones (correlation coefficients 0.63 and 0.57, respectively). Male subjects attained significantly higher scores for hyperthymic temperament, compared to females, while females scored significantly higher than males on cyclothymic and anxious temperaments. LIMITATIONS Our healthy young subjects are not representative of the Polish population. As external validation has been achieved in other language versions, it was not repeated in the present Polish version. CONCLUSIONS The Polish version of TEMPS-A has a good internal consistency. The findings generally cohere with those from previously validated versions in other languages.

Affective temperaments, as measured by TEMPS-A, among nonviolent suicide attempters. J Affect Disord 2009; 116:18-22. [PMID: 19036456 DOI: 10.1016/j.jad.2008.10.024] [Citation(s) in RCA: 64] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2008] [Revised: 10/30/2008] [Accepted: 10/30/2008] [Indexed: 11/26/2022]
Abstract
BACKGROUND The aim of this study was to investigate the role of affective temperaments in suicidal behavior. METHOD Using the standardized Hungarian version of the full-scale 110-item version of the TEMPS-A autoquestionnaire we compared the affective temperament-profiles of 150 consecutively investigated nonviolent suicide attempters (106 females and 44 males) and 302 age, sex and education matched normal controls (216 females and 86 males). RESULTS Compared to controls, both female and male suicide attempters scored significantly higher in the four of the five affective temperaments, containing more or less depressive component (depressive, cyclothymic, irritable and anxious). On the other hand, however, no significant difference between the suicide attempters and controls was found for the hyperthymic temperament. Significantly higher rate of suicide attempters (90.0%) than controls (21.5%) have had some kind of dominant (mean score+2SD or above) affective temperament. Compared to controls, depressive, cyclothymic, irritable and anxious temperaments were significantly more frequent and hyperthymic temperament was nonsignificantly less common among suicide attempters. CONCLUSIONS The findings support the strong relationship between depression and suicidal behavior even on temperamental level, and suggest that hyperthymic temperament does not have predisposing role for suicidal behavior at least in the case of nonviolent suicide attempters. LIMITATION As only nonviolent suicide attempters were studied, our findings should pertain only for this patient-population.

Abstract
BACKGROUND Earlier studies have suggested a relationship between bipolar disorder (BP) and eating disorders (ED), more specifically, bulimia nervosa (BN) and bipolar II disorder (BP-II). In the present report we extend this relationship to broader definitions of bipolarity. METHODS Semi-structured interview of 201 patients with DSM-IV criteria for major affective disorders combined with Akiskal and Mallya criteria for Affective temperaments. To diagnose lifetime comorbid eating disorders DSM-IV criteria for eating disorders (Bulimia Nervosa, BN, Anorexia, AN) were used. RESULTS 33 patients had an eating disorder. When compared to patients without ED the patients with ED had a higher prevalence of bipolar disorders. Using strict DSM-IV criteria, this association was only significant for BN (OR) 4.5 (95% CI 1.1-17.6). When using a broader index of bipolarity including patients having affective temperaments, a significant relation was found for BN (OR) 9.1 (95% CI 1.1-73.6), and for patients with a lifetime history of both BN and AN (OR) 8.6 (95% CI 1.1-70.2).We also found patients with ED to have a significantly higher prevalence of affective temperaments, an earlier onset of major affective disorder and to have more depressive episodes. LIMITATIONS Non-blind evaluation of diagnosis for mood, eating disorders and affective temperaments. CONCLUSION In line with previous reports we describe an association between bulimia nervosa and bipolar disorder. Furthermore we report a relationship between lifetime bulimia and anorexia and cyclothymic and related affective temperaments.

Abstract
BACKGROUND The objective of this cross-sectional study was to determine the prevalence of migraine headache among depressed Latino adults of Mexican American origin meeting the criteria for bipolar disorder (BPD) or major depressive disorder (MDD) relative to patients in a psychiatric comparison group. METHOD In a mental health clinic for the indigent, consecutively and systematically evaluated acutely depressed Latino adults received structured diagnostic psychiatric interviews based on modules extracted from the Structured Clinical Interview for DSM-IV. All were asked as part of routine assessment whether they had headaches "in the last week." Patients with unilateral, pounding, pulsating headache were classified as having migraine headache. The prevalence of migraine headache among the patients with BPD and MDD was contrasted with that of patients in a psychiatric comparison group composed of patients with disorders other than schizophrenia or schizoaffective disorder. Logistic regression was used to test for associations and control for confounding effects. The data were collected between August 2001 and November 2004. RESULTS Eighty-seven patients had BPD and 123 had MDD. Bipolar patients were 2.9 times more likely to have migraine headaches than patients with MDD (P < .0001). There was a trend for patients with MDD to have a higher prevalence of migraine than patients in the psychiatric comparison group. CONCLUSIONS Bipolar patients had a high prevalence of migraine headache relative to patients with MDD. This study suggests that migraine is linked to bipolarity.

Towards a genetically validated new affective temperament scale: a delineation of the temperament phenotype of 5-HTTLPR using the TEMPS-A. J Affect Disord 2009; 112:19-29. [PMID: 18455241 DOI: 10.1016/j.jad.2008.03.012] [Citation(s) in RCA: 36] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/04/2008] [Revised: 03/19/2008] [Accepted: 03/19/2008] [Indexed: 12/31/2022]
Abstract
BACKGROUND Although it has been described that affective temperaments are associated with the 5-HTTLPR, less attention was paid to the association between this polymorphism and subscales and items related to each affective temperament. The aim of our study was to investigate the association of affective temperament subscales and individual items with the s allele of the 5-HTTLPR. METHOD 138 psychiatrically healthy women completed the TEMPS-A questionnaire and were genotyped for 5-HTTLPR. Scores of subjects on the temperament scales, subscales and items in the three genotype and the two phenotype groups were compared using ANOVA. We selected items with significantly different mean scores between the three genotype groups and the two phenotype groups separately and performed item analysis. RESULTS Subjects in the different 5-HTTLPR genotype and phenotype groups have significantly different score on scales measuring depressive, cyclothymic, irritable and anxious temperaments, and several subscales composing these temperamental scales. Subjects in the three genotype groups scored significantly different on 11 items, 8 of these remained in a derived genotype scale after item analysis. Subjects in the two phenotype groups had significantly different scores on 12 items, 9 of them were retained in a derived phenotype scale after item analysis. LIMITATIONS Our sample was relatively small and included only women. CONCLUSIONS Our data provide support for the association of affective temperaments with the s allele. Although the cyclothymic temperament shows the strongest association, all temperaments within the depressive superfactor have a similar share in this association. The newly derived 5-HTTLPR Phenotype Scale shows strong association with 5-HTTLPR genotype and phenotype, therefore this scale should be further investigated in relation to psychiatric disorders, as well as psychological traits and temperaments.

Validation of the Temperament Evaluation of Memphis, Pisa, Paris and San Diego (TEMPS-A): Portuguese-Lisbon version. J Affect Disord 2008; 111:193-203.

Abstract
BACKGROUND The TEMPS-A has been validated in 8 languages, the original being American English, and includes among others such Latin languages as Italian, French, and Spanish-Buenos Aires. This is the first Portuguese-Lisbon validation. METHODS The sample included 1173 students from six different universities and representing most disciplines (such as medicine, law, humanities, engineering, etc.), both sexes (67% female), and ages between 17 and 58 (x+/-SD=21+/-4). Standard psychometric tests were used for internal consistency, validity, and factor analysis. RESULTS The study upheld the 5 Factor proposed structure of TEMPS-A. Cronbach alpha varied from 0.67 for the depressive and 0.83 for the anxious, with the others in-between. We could retain all 110 items of the Interview Schedule. The highest mean scores were found for the hyperthymic, and the lowest for the irritable. As expected, depressive and anxious subscales had strong correlations, followed by the cyclothymic and anxious, and cyclothymic and irritable; in exploratory factor analysis, these subscales constituted Factor I, contrasted to the depressive and the hyperthymic as a biphasic continuum (Factor II). Females scored higher on the depressive, cyclothymic and anxious, and the males on hyperthymic and irritable. Overall, however, no temperament was "dominant" in this population, all temperaments z-scores being 3.3-4%! LIMITATIONS Study limited to university students of young age. CONCLUSIONS TEMPS-A Lisbon is a reliable and valid instrument. The only relatively weak factor is the depressive, which is similar to other language versions. Gender differences and correlations of temperaments are generally similar to other countries. What appears relatively special to the Portuguese is the relatively "balanced" mix of temperaments in this university student population.

The clinical-familial correlates and naturalistic outcome of panic-disorder-agoraphobia with and without lifetime bipolar II comorbidity. Ann Gen Psychiatry 2008; 7:23.

Abstract
BACKGROUND Much of the literature on panic disorder (PD)-bipolar disorder (BP) comorbidity concerns BP-I. This literature emphasizes the difficulties encountered in pharmacologic treatment and outcome when such comorbidity is present. The present report explores these issues with respect to BP-II. METHODS The sample comprised 326 outpatients (aged 34.5 +/- 11.5 years old; 222 females) with Diagnostic and Statistical Manual of Mental Disorders 3rd edn, revised (DSM-III-R) PD-agoraphobia; among them 52 subjects (16%) were affected by lifetime comorbidity with BP-II. Patients were evaluated by means of the Structured Clinical Interview for DSM-IV (SCID), the Panic-Agoraphobia Interview, and the Longitudinal Interview Follow-up Examination (Life-Up) and treated according to routine clinical practice at the University of Pisa, Italy, for a period of 3 years. Clinical and course features were compared between subjects with and without BP-II. All patients received the clinicians' choice of antidepressants and, in the case of the subsample with BP-II, mood stabilizers (for example, valproate, lithium) were among the mainstays of treatment. RESULTS In comparison to patients without bipolar comorbidity, those with BP-II showed a significantly greater frequency of social phobia, obsessive-compulsive disorder, alcohol-related disorders, and separation anxiety during childhood and adolescence. Regarding family history, a significantly greater frequency of PD and mood disorders was present among the BP-II. No significant differences were observed in the long-term course of PD or agoraphobic symptoms under pharmacological treatment or the likelihood of spontaneous pharmacological treatment interruptions. CONCLUSION Although the severity and outcome of panic-agoraphobic symptomatology appear to be similar in patients with and without lifetime bipolar comorbidity, the higher number of concomitant disorders in our PD patients with BP-II does indicate a greater complexity of the clinical picture in this naturalistic study. That such complexity does not seem to translate into poorer response and outcome in those with comorbid soft bipolarity probably reflects the fact that we had brought BP-II under control with mood stabilizers. We discuss the implications of our findings as further evidence for the existence of a distinct anxious-bipolar diathesis.

Abstract
BACKGROUND To determine the lifetime rates of panic disorder, obsessive-compulsive disorder (OCD), social phobia, and posttraumatic stress disorder (PTSD) among adult Latino patients with major depressive disorder (MDD) and bipolar disorder (BPD), and whether there are dose-response relationships between loading for comorbid anxiety disorders, the probability of having BPD, and attributes of severity of illness. METHODS In a public sector clinic for the indigent located in a semiclosed rural community, 187 consecutively presenting affectively ill Latino patients were evaluated by use of the Structured Clinical Interview for DSM-IV. Polarity and the lifetime prevalence of panic disorder, OCD, social phobia, and PTSD were determined. Logistic regression was used to test associations. Trends in positive predictive values (PPVs) and likelihood ratios were assessed to determine whether dose-response relationships existed between loading for comorbid anxiety disorders and the likelihood of having BPD as opposed to MDD, psychosis, suicidal ideation, and suicide attempts. RESULTS Of 187 subjects, 118 (63.1%) had MDD and 69 (36.9%) had BPD. The odds ratio of a patient with BPD, relative to MDD, of having panic disorder was 4.6 (p< .0001), OCD 7.6 (p< .0001), social phobia 6.0 (p< .0001) and PTSD 5.3 (p< .0001). The PPV of having BPD was 91.3% and of having psychotic features 83.0% if one had all four anxiety disorders. There was a dose-response relationship between loading for comorbid anxiety disorders and the likelihood of having had a suicide attempt (but not suicidal ideation). CONCLUSIONS As previously reported by us for juvenile patients, Latino adults with BPD had a remarkably high risk of having each anxiety disorder relative to patients with MDD. The results indicate that the risk of having BPD, having a psychosis, and making a suicide attempt becomes increasingly great as the number of comorbid anxiety disorders increases. These data, which are consistent with the notion of anxious bipolarity, provide further support for a possible anxious diathesis in bipolar disorder.

Abstract
BACKGROUND The purpose of this study is to examine the prevalence of affective temperaments between clinically unaffected relatives of bipolar patients and secondarily to investigate the impact of these "subaffective" forms on their quality of life (QoL). METHODS The study was performed in seven sites across Argentina. We administered the scales TEMPS-A and Quality of Life Index to a sample of 114 non-ill first degree relatives of bipolar disorder patients ("cases") and 115 comparison subjects without family history of affective illness ("controls"). We used The Mood Disorder Questionnaire to rule out clinical bipolarity. RESULTS Mean scores on all TEMPS-A subscales were significantly higher in cases, except for hyperthymia. The prevalence of affective temperaments, according to Argentinean cut-off points, was also higher, with statistical significance for cyclothymic and anxious temperaments. Regarding QoL, we found no significant differences between both groups, except for interpersonal functioning, which was better in controls. A detailed subanalysis showed significant effects of QoL domains for all temperaments, except for the hyperthymic. LIMITATIONS We used self-report measures. A larger sample size would have provided us greater statistical power for certain analyses. CONCLUSIONS Our findings support the concept of a spectrum of subthreshold affective traits or temperaments - especially for the cyclothymic and anxious - in bipolar pedigrees. We further demonstrated that, except for the hyperthymic, quality of life was affected by these temperaments in "clinically well" relatives. Overall, our data are compatible with the "endophenotype" and "subaffective" theses for affective temperaments.

TEMPS-A (Rome): psychometric validation of affective temperaments in clinically well subjects in mid- and south Italy. J Affect Disord 2008; 107:63-75. [PMID: 17884175 DOI: 10.1016/j.jad.2007.07.031] [Citation(s) in RCA: 72] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/05/2007] [Accepted: 07/31/2007] [Indexed: 01/06/2023]
Abstract
BACKGROUND Our aim was to study the psychometrics and factor structure replicability of the Temperament Evaluation of Memphis, Pisa, Paris and San Diego Autoquestionnaire (TEMPS-A) in its Italian (Rome) Version. The questionnaire is a self-report 110-item measure that postulates five affective temperaments-the depressive, cyclothymic, irritable, hyperthymic, and anxious-which embody both strengths and liabilities along affective reactivity. In Italian, the TEMPS has previously been validated in its original 32-item version, the TEMPS-I (Pisa), one which did not yet include an anxious subscale. METHODS The present sample consisted of 948 nonclinical subjects (27.39 years+/-8.22 S.D.). There were 476 men (50.2%: 28.56 years+/-8.63 S.D.) and 472 women (49.8%: 26.21 years+/-7.61 S.D.). Reliability and validity were assessed by standard psychometric tests. RESULTS Principal Components Analysis with Varimax rotation resulted in a 3-factor solution: the first with highest explained variance (8.84%) represents Dysthymic, Cyclothymic and Anxious (Dys-Cyc-Anx) temperaments combined; the second identifies Irritable temperament (5.65% of variance); and the third Hyperthymic temperament (5.16% of variance). Cronbach Alpha coefficients for the three subscales were respectively .89, .77 and .74. The rates for the Dys-Cyc-Anx were 2.7%, and for the Irritable 3.1%. Despite the low rate of the Hyperthymic temperament (.2%), nonetheless 16% were between 1st and 2nd SD. Exploratory factor analysis revealed a positive loading combining Dys-Cyc-Anx with the Irritable; the Hyperthymic loaded negatively on this factor. In terms of dominant temperaments, based on z-scores, 2.7% were dysthymic, 1.7% cyclothymic, .7% hyperthymic, 3.5% irritable and 3% anxious. LIMITATION Although developed for self-rated use, the Italian authors nonetheless administered the TEMPS-A in an interview format. It is uncertain in what ways this procedure could have influenced our results, if any. Another limitation is that we did not assess test-retest reliability. CONCLUSIONS These data identify at least 3-factors, Dys-Cyc-Anx and Irritable (which are correlated), and Hyperthymic, which is uncorrelated with the others. Though our data are reminiscent of the neuroticism-extraversion distinction, importantly traits are operationalized in affective terms. Beyond the well-known relationship between the Dysthymic and Cyclothymic subscales and that between the Dysthymic and Anxious, the present data reveal a strong relationship between the Cyclothymic and Anxious as well, which is of great relevance for bipolar II. It is also provocative that much of hyperthymia (16%) in the +SD is between the 1st and 2nd SD, thereby "normalizing" this temperament in Italy, as previously reported by TEMPS-I (Pisa) from Northern Italy (and TEMPS-A from Lebanon and Argentina).

A study of affective temperaments in Hungary: internal consistency and concurrent validity of the TEMPS-A against the TCI and NEO-PI-R. J Affect Disord 2008; 106:45-53. [PMID: 17706791 DOI: 10.1016/j.jad.2007.03.016] [Citation(s) in RCA: 77] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2007] [Accepted: 03/13/2007] [Indexed: 11/28/2022]
Abstract
BACKGROUND TEMPS-A (Temperament Evaluation of the Memphis, Pisa, Paris and San Diego - Autoquestionnaire) is a new self-assessed temperament 110-item scale with depressive (D), cyclothymic (C), hyperthymic (H), irritable (I) and anxious (A) subscales. To date, it has been translated into 25 languages, and validated in 10. The present Hungarian version provides the most complete external validation across the Beck Depression Scale (BDI), Profile of Mood States (POMS), the BarOn Emotional Quotient Inventory (BarOn EQ-i), Temperament and Character Inventory (TCI), and the NEO Personality Inventory - Revised (NEO-PI-R). We were particularly interested in concurrent validation against the TCI and the NEO-PI-R, the most important of the new personality instruments. METHODS 1132 clinically-well subjects (27% male) from the general population and university students (16-81 years) were administered the above scales and instruments. The data were tested with standard psychometric batteries. RESULTS Factor analysis revealed 5 factors approximating the original D, C, I, H, and A subscales, which in their superfactor confirmed an Emotional (D, C, I, A) vs. Hyperthymic structure. Except for the D (a=0.65), the Cronbach alpha for the remainder temperaments ranged from 0.75-0.81. Dominant temperaments ranged from the I (2.7%) to the C (4.2%); the highest prevalence was observed among men with C=6% and H=5.4%. The BDI and POMS correlated significantly with the relevant subscales, as did the BarOn. Of the many significant possible correlations with the TCI, the most noteworthy were novelty seeking and harm avoidance with D, A, C, as well as C, and persistence with H. As for the NEO-PI-R, we were struck by the positive correlation of openness with C, and conscientiousness negatively with C; most other positive correlations such as neuroticism with all temperaments but the hyperthymic were expected and strongly supportive of concurrent validity. LIMITATIONS Higher educational background of the subjects studied relative to that of the general population of Hungary. The distribution of the data may have in some instances deviated somewhat from the underlying assumptions for the standard psychometric tests for normality. We did not conduct test-retest reliability. CONCLUSIONS The factorial structure of the TEMPS-A shows good reliability and internal consistency. Although the superstructure is reminiscent of neuroticism-extraversion, within it are embedded discernible classical affective temperaments. A provocative finding is the high prevalence of cyclothymia in Hungarian males (6%), which is rather unique when compared with the other 10 countries studied to date. This finding, coupled with high male hyperthymia (5.4%), may explain the high lifetime prevalence of bipolar disorders reported from Hungary. Inter alia, our psychometric data along with the foregoing epidemiologic considerations, are very much in line with the cyclothymic-bipolar spectrum model proposed by the senior author [Akiskal, H.S., Djenderedjian, A.H., Rosenthal, R.H., Khani, M.K., 1977. Cyclothymic disorder: validating criteria for inclusion in the bipolar affective group. Am. J. Psychiatry 134, 1227-1233].

Temperament and personality dimensions in suicidal and nonsuicidal psychiatric inpatients. Psychopathology 2008; 41:313-21.

Abstract
BACKGROUND Suicide is a serious public health problem. In the international literature there is evidence to support the notion that certain temperaments and personality traits are often associated with suicidal behavior. SAMPLING AND METHODS In this study, 150 psychiatric inpatients were investigated using the Temperament Evaluation of Memphis, Pisa, Paris and San Diego autoquestionnaire, the Minnesota Multiphasic Personality Inventory, 2nd edition (MMPI-2) and the Beck Hopelessness Scale and evaluated for suicide risk by means of the critical items of the Mini International Neuropsychiatric Interview. RESULTS Statistical analysis, including logistic regression analysis and multiple regression analysis, showed that suicide risk contributed to the prediction of hopelessness. Among the temperaments, only the hyperthymic temperament, as a protective factor, and the dysthymic/cyclothymic/anxious temperament contributed significantly to the prediction of hopelessness. Irritable temperament and social introversion were predictive factors for suicidal risk. Hopelessness and depression were associated with higher suicidal behavior and ideation, but, unexpectedly, depression as measured by the MMPI did not contribute significantly to the multiple regressions. CONCLUSIONS The present study indicated that, although suicidal psychiatric patients have MMPI-2 profiles in the pathological range, they exhibit several differences from nonsuicidal patients. Patients at risk of suicide have specific temperaments as well as personality and defense mechanism profiles. They are more socially introverted, depressed and psychasthenic, and use hysterical and schizoid mechanisms more often. Generalizability of the findings was limited by the small sample size and the mix of bipolar disorder I, bipolar disorder II, major depressive disorder and psychotic disorder patients.

Abstract
OBJECTIVES The aims of this cross-sectional pilot study were to ascertain the rates of post-traumatic stress disorder (PTSD) among adolescents with bipolar disorder (BPD) and major depressive disorder (MDD) relative to a comparison group comprised of non-affectively ill patients, and to determine whether PTSD is related to suicidal ideation and attempts. The impetus for the study was born of clinical impressions derived in the course of routine clinical practice. METHODS Patients were screened by a single interviewer for BPD, MDD and PTSD, panic disorder, obsessive-compulsive disorder (OCD) and social phobia using the apposite modules from the Structured Clinical Interview for DSM-IV (SCID) and histories of suicidal ideation and attempts. The data were subjected to analysis using a logistic regression model. RESULTS The database included 34 patients with BPD, 79 with MDD and 26 with a non-affective disorder. The risk for PTSD for a patient with BPD significantly exceeded that for a patient with MDD [odds ratio (OR) = 4.9, 95% confidence interval (CI) = 1.9-12.2, p = 0.001]. Patients with PTSD had an insignificantly increased risk for suicidal ideation (OR = 2.8, 95% CI = 0.9-8.9, p = 0.069), and a 4.5-fold significantly increased risk of having had a suicide attempt (OR = 4.5, 95% CI = 1.7-11.7, p = 0.002). The relationship between PTSD and suicide attempts remained significant even after controlling for the confounding effects of concurrent panic disorder, OCD and social phobia (OR = 3.4, 95% CI = 1.1-10.0, p = 0.023). CONCLUSIONS Patients with BPD have a greater risk for PTSD than those with MDD. Post-traumatic stress disorder is significantly related to history of suicide attempts.

Abstract
BACKGROUND The TEMPS-A (Temperament Evaluation of Memphis, Pisa, Paris and San Diego) is a 110-item questionnaire in five scales which has been translated into over 25 language versions: American, Italian (only for Interview version or TEMPS-I), French, Lebanese, Hungarian, Japanese and Turkish versions have already been validated. There are two Spanish versions, one from Barcelona, and the present one from Buenos Aires. This study represents the first attempt at validating the TEMPS-A in Spanish. METHODS 932 clinically well subjects were studied, of both sexes (62% female) with mean+/-SD age of 35.4+/-18.1. Standard psychometric tests of reliability and validation were performed. RESULTS Chronbach alphas were 0.7 (depressive) and 0.8 (anxious, cyclothymic, irritable and hyperthymic). In exploratory factor analyses, the hyperthymic was distinct from the others. As expected, the depressive and anxious correlated strongly, so did the cyclothymic and anxious. Dominant temperaments ranged from 2.1% to 4.5% of the population under study, except for the hyperthymic which had a negligible rate of 0.2% (but accounted for 13% between +1 SD and +2 SD). LIMITATION We did not examine test-to-test reliability. CONCLUSIONS This is the first validation of the TEMPS-A in Spanish, the Buenos Aires version with the original 110 items, with very good psychometric properties.

Abstract
Is suffering associated with melancholia and "madness" necessary for artistic creativity and eminence? Or do creativity and leadership have something to do with the temperaments associated with affective disease? We integrate concepts dating back to Greek psychological medicine and philosophy--especially work attributed to Aristotle--with modern data-based examination of the role of cyclothymic and related temperaments in the interface between mixity, the bipolar spectrum and normality. We place our query within the general framework of evolutionary biology and human nature. In doing so, we propose that affective disease--including mania and associated psychotic states--exist because they serve as the genetic reservoir for adaptive temperaments and the genes for genius. Affective disorder can therefore be regarded as the price of exceptional greatness. Thus, creative and eminent individuals, by virtue of their being exceptional, occupy a somewhat unstable terrain between temperament and affective disease.

Suitability of the TEMPS-A for population-based studies: ease of administration and stability of affective temperaments in its Lebanese version. J Affect Disord 2007; 98:45-53.

Abstract
BACKGROUND The Temperament Evaluation of Memphis Pisa Paris and San Diego Auto-questionnaire (TEMPS-A) has been translated and validated into several languages, and used in different subgroups (e.g. clinical, students, company, employees and those with different educational levels). METHODS Lebanon is the only country that has validated the TEMPS-A in a national cohort, as part of the Lebanese Evaluation of the Burden of Ailments and Needs Of the Nation (LEBANON). In this paper, we test the suitability of the TEMPS-A for large scale epidemiologic population-based studies. RESULTS 82.1% of the respondents found the TEMPS-A to be easy to understand. The global reports of the Lebanese of their own temperaments paralleled those of the formal sub-scores on the five affective temperament subscales. The majority of respondents (90.3%) felt that their answers on the Lebanese-Arabic TEMPS-A scale represented them throughout their adulthood; the minority who did not were more likely to be older, and to have scored higher on the cyclothymic, and lower on the hyperthymic subscales. LIMITATION Although the TEMPS-A has been designed for self-administration (auto-questionnaire), this was not practical in all subjects. We nonetheless feel that the interview format is viable as it introduces flexibility with certain subjects in population studies. CONCLUSIONS The TEMPS-A appears to be suitable for use in epidemiologic surveys and research.

Abstract
OBJECTIVE We argue for a mixed state core for melancholia comparing concepts of melancholia across centuries using examples from art, history and scientific literature. METHOD Literature reviews focusing on studies from Kraepelin onward, DSM-IV classification and view-points from clinical experience highlighting phenomenologic and biologic features as predictors of bipolar outcome in prospective studies of depression. RESULTS Despite the implied chemical pathology in the term endogenous/melancholic depression, frequently reported glucocortical and sleep neurophysiologic abnormalities, there is little evidence that melancholia is inherited independently from more broadly defined depressions. Prospective follow-up of 'neurotic' depressions have shown melancholic outcomes in as many as a third; hypomania has also been observed in such follow-up. CONCLUSION These findings and considerations overall do suggest that melancholia as defined today is more closely aligned with the depressive and/or mixed phase of bipolar disorder. Given the high suicidality from many of these patients the practice of treating them with antidepressant monotherapy needs re-evaluation.

Dose-response relationship between number of comorbid anxiety disorders in adolescent bipolar/unipolar disorders, and psychosis, suicidality, substance abuse and familiality. J Affect Disord 2006; 96:249-58.

Abstract
OBJECTIVES To ascertain rates of panic, obsessive-compulsive (OCD) and social phobic disorders among adolescents with bipolar disorder (BP), unipolar major depressive disorder (MDD) and psychiatric comparison patients, to assess their relationships to suicidality, psychosis, comorbidity patterns and familiality. METHODS The first author (SCD) interviewed 313 Latino adolescents using a structured interview based on the SCID. Family history was ascertained by live interview or interview by proxy. Patients were classified as BP, MDD, or non-affectively ill comparison controls (CC). Data regarding suicidality and psychosis were collected. Regression analysis was used to test associations and control for confounding effects. Positive likelihood ratios were used to measure the dose-response relationships between number of anxiety disorders and measures of severity of illness and familial loading for affective illness. RESULTS Of the total sample, 36.7% were BP, 44.7% MDD and 18.5% CC. In BP vs. MDD the odds of panic disorder were 4.4, of OCD 5.1, and of social phobia 3.3. MDD, in turn, were more likely to have these disorders than CC. BP (but not MDD) with panic disorder and social phobia, were more likely to have suicidal ideation; among the anxiety disorders, only social phobia was associated with having greater odds of suicide attempts. Among BP and MDD, patients with all three anxiety disorders were more likely to be psychotic. Presence of any mood disorder among first-degree relatives substantially increased the odds of having panic disorder and social phobia. The presence of one comorbid anxiety disorder increased the odds of having another. Finally, there were dose-response relationships between number of anxiety disorders and measures of severity of illness and familial loading for affective illness. LIMITATIONS Single interviewer using the SCID; cross sectional exploratory study. CONCLUSIONS BP adolescents have a greater anxiety disorder burden than their MDD counterparts. The results are compatible with the hypothesis that heavy familial-genetic loading for affective illness in juveniles is associated with bipolarity, cumulative anxiety disorder comorbidity, suicidality and psychosis. These observations are in line with pioneering psychopathologic observation in the early 1900s by two French psychiatrists, Gilbert Ballet and Pierre Kahn, who saw common ground between what until then had been considered the distinct categories of the neuroses and cyclothymic (circular) psychoses. This perspective has much in common with current complex genetic models of anxious diatheses in bipolar disorder.

Validating the bipolar spectrum in the French National EPIDEP Study: overview of the phenomenology and relative prevalence of its clinical prototypes. J Affect Disord 2006; 96:197-205.

Abstract
BACKGROUND Few studies have been undertaken to ascertain the feasibility of using the bipolar (BP) spectrum in clinical practice. The only systematic national study is the French EPIDEP Study of consecutive inpatients and outpatients presenting with major depressive episodes (MDE). The protocol was developed in 1994 and implemented in 1995; publication of its first data began in 1998. This report provides the complete data set of the EPIDEP. METHODS Forty-eight psychiatrists, practicing in 15 sites in four regions of France (Paris, Besançon, Bordeaux and Marseille), were all trained on a common protocol based on DSM-IV criteria for MDE (n=537) subdivided into BP-I (history of mania), BP-II (history of hypomania), as well as extended definitions of the "softer spectrum" beyond BP-I and BP-II. Measures tapping into this spectrum included the Hypomania Checklist (HCA), the cyclothymic (CT), depressive (DT) and hyperthymic (HT) temperament scales. These measures and course permitted post-hoc assignment of MDE in the bipolar spectrum, based in part on the Akiskal, H.S., Pinto, O., 1999. [The evolving bipolar spectrum: Prototypes I, II, III, IV. Psychiatr. Clin. North Am. 22, 517-534] proposal: depression with history of spontaneous hypomanic episodes (DSM-IV, BP-II), cyclothymic depressions (BP-II(1/2)), antidepressant-associated hypomania (BP-III) and hyperthymic depressions (BP-IV). <<Strict UP>> was thereby limited to an exclusion diagnosis for the remainder of MDE. LIMITATION In the clinical setting, psychiatrists cannot be entirely blind to the observations in the various clinical evaluations and instruments. However, the systematic multisite collection of such data tended to minimize any such biases. RESULTS After excluding patients lost to follow-up, among 493 presenting with MDE with complete data files, the BP-II rate was estimated at index at 20%; 1 month later, systematic probing for hypomania doubled the rate of BP-II to 39%. The comparison between BP-II and UP showed differential phenomenology, such as hypersomnia, increased psychomotor activation, guilt feelings and suicidal thoughts in BP-II. Related data demonstrated the importance of CT in further qualifying of MDE to define a distinct, more severe ("darker") BP-II(1/2) variant of BP-II. Moreover, BP-III, arising from DT and associated with antidepressants, emerged as a valid soft bipolar variant on the basis of the phenomenology of hypomania and bipolar family history. Finally, we found preliminary evidence for the inclusion of BP-IV into the bipolar spectrum, its total hypomania score falling intermediate between BP-II and strict UP. Using this broader diagnostic framework, the bipolar spectrum (the combined "hard" BP-I phenotype, BP-II and the soft spectrum) accounted for 65% of MDE. CONCLUSION The EPIDEP study achieved its objectives by demonstrating the feasibility of identifying the bipolar spectrum at a national level, and refining its phenomenology through rigorous clinical characterization and validation of bipolar spectrum subtypes, including MDE with brief hypomanias, cyclothymia and hyperthymia. The spectrum accounted for two out of three MDE, making "strict UP" less prevalent than BP as redefined herein. Our findings were anticipated by Falret, who in 1854 had predicted that many melancholic patients in the community would 1 day be classified in his circular group. We also confirmed Baillarger's observation in the same year that episodes (in this study, hypomanic episodes) could last as short as 2 days. Our findings deriving from a systematic French national database a century and a half later invite major shifts in clinical and public health services, as well as in the future conduct of psychopharmacologic trials. In this respect, the systematic training of clinicians in four regions of France represents a national resource for affective disorders and can serve as a model to effect change in diagnostic practice in other countries.

Validating the soft bipolar spectrum in the French National EPIDEP Study: the prominence of BP-II 1/2. J Affect Disord 2006; 96:207-13.

Abstract
BACKGROUND Much of the current literature on bipolar disorder is focused on bipolar I (BP-I), and to a much lesser extent on bipolar II (BP-II). The French multi-center national EPIDEP study has, among its objectives, the feasibility of validating a broader spectrum of bipolarity (the so-called "soft spectrum") by practicing clinicians. In this report we test aspects of a bipolar schema proposed earlier by Akiskal and Pinto [Akiskal, H.S., Pinto, O., 1999. The evolving bipolar spectrum: Prototypes I, II, III, IV. Psychiatr. Clin. North Am. 22: 517-534.]. METHODS EPIDEP was scheduled in three phases: Phase 1 to recruit DSM-IV major depressives; Phase 2 to assess hypomania and affective temperaments; and Phase 3 to obtain history on course of illness, family history, and comorbidity. Comparative analyses are presented between affective subgroups constructed on a hierarchical basis: spontaneous hypomania (BP-II), cyclothymic temperament (BP-II 1/2), antidepressant-associated hypomania (BP-III), hyperthymic temperament (BP-IV), versus "strict unipolar" (UP). RESULTS We present data on 490 patients for whom we obtained full assessment during all three phases of the study, classified as BP-II 1/2 (N=164), II (N=61), III (N=28), IV (N=22), as well as UP (N=174) as the reference nonbipolar group. Systematic inter-group comparison among the soft spectrum showed significant differences along clinical, descriptive, course, pharmacologic response and familial affective disorder patterns, which confirm the heterogeneity of the soft bipolar spectrum, with special characteristics for each of the subgroups. In terms of external validation, familial bipolar loading characterized all soft bipolar subgroups except type IV. LIMITATION Data collection conducted in a practice setting, clinicians cannot be entirely held "blind" to all measures. This is an exploratory attempt, with many variables examined, to help characterize the clinical terrain of soft bipolarity. CONCLUSION This is nonetheless the first systematic clinical attempt to validate the bipolar spectrum beyond mania (BP-I). BP-II 1/2, BP-III and BP-IV appeared distinct from BP-II and strict UP -- along most of the variables examined. BP-II 1/2 -- with early onset complex temperament structure, and high mood instability, rapid switching, irritable ("dark") hypomania and suicidality -- emerged as the most prevalent and severe expression of the bipolar spectrum, and accounting for 33% of all MDE. These results, which are of great public health relevance, testify to the cyclic nature of bipolarity in its softest expressions. The soft phenotypes are also of interest for genetic investigations of bipolar disorder.

Abstract
OBJECTIVE In DSM-IV, bipolar II (BP-II) disorder is defined by depression and hypomania. There is little appreciation of affective instability, often associated with anxiety-particularly panic disorder and agoraphobia (PDA)-comorbidity. This association has genetic-familial implications, which we believe must be incorporated in refining the BP-II phenotype suitable for genotyping purposes. METHOD We examined in a semi-structured format 107 consecutive patients who met DSM-IV criteria for major depressive episode with atypical features and separated them into two subgroups according to the co-occurring criteria for PDA. They were further evaluated on the basis of the Atypical Depression Diagnostic Scale (ADDS), the Hopkins Symptoms Check-list (HSCL 90), and the Hamilton Rating Scale for Depression (HRSD), coupled with its modified form for reverse vegetative features, as well as Axis I and II comorbidity and temperamental dispositions, particularly cyclothymic instability. RESULTS Fifty (46.7%) of our patients met the DSM-IV criteria for PDA. In terms of significant results, PDA+ was more frequently female, had higher number of hypomanic episodes, and stressors; they were also more often BP-II, and cyclothymic. Ratings of reactivity, somatization, OCD and phobic anxiety too were significantly higher among the PDA+. In related analyses, most AD (75.7%) met criteria for BP-II; the BP-II subgroup was characterized by PDA, as well as borderline personality features and cyclothymic and hyperthymic temperaments. LIMITATIONS Correlational clinical study in which clinicians could not be kept entirely blind to the variables under investigation. CONCLUSIONS In line with the description by the French psychiatrist Pierre Kahn a century earlier, cyclothymic reactivity and neurotic features (i.e., atypicality and panic attacks) appear relevant to the definition of what today we consider BP-II disorder. These data, which are in line with current familial-genetic models of this disorder, suggest that the DSM-IV characterization of BP-II must be enriched by greater emphasis on temperamentally based mood and anxious reactivity. Such phenotypic characterization is likely to assist in better genotyping. Previous work by us further suggests the relevance of bulimic and addictive tendencies, as well as "borderline personality" diagnosis in the proband and/or the family. We submit that these conditions, rather than being "comorbid," constitute, along with BP-II, a spectrum of overlapping underlying genetic diatheses.

Abstract
OBJECTIVE Recent data indicate significant clinical, biological, and treatment response overlap between eating and bipolar disorders, especially when soft symptoms of either spectrum disorders are considered. The aim of the present analyses is to evaluate the lifetime prevalence of bulimia nervosa (BN) in patients with atypical depression (AD) and to delineate any demographic, clinical, personality or temperamental factors that may characterize this subgroup. METHOD We examined in a semi-structured format 107 consecutive patients who met DSM-IV criteria for major depressive episode with atypical features and we separated them into two groups according to the co-occurring criteria for BN. They were further evaluated on the basis of the Atypical Depression Diagnostic Scale (ADDS), the Hopkins Symptoms Check-list (HSCL 90), and the Hamilton Rating Scale for Depression (HRSD), coupled with its modified form for reverse vegetative features, as well as Axis I and II comorbidity and temperamental dispositions. RESULTS Seventeen (17.8%) percent of AD met the DSM-IV criteria for Bulimia Nervosa (BN+). These patients, compared with those who did not meet criteria for BN (BN-), were indistinguishable on all demographic and most psychopathologic and clinical features (including bipolar I and II), but were significantly higher in lifetime comorbidity for Narcissistic, Histrionic, Borderline and Dependent personality disorders as well as that for Cyclothymic temperament. BN+ also scored higher on the ADDS items of reactivity of mood and interpersonal sensitivity. LIMITATIONS Correlational clinical study in which doctors could not be entirely blind to the variables under investigation. CONCLUSIONS Cyclothymic temperament and related mood reactivity and interpersonal sensitivity may account for much of the relationship between AD and BN. Narcissistic, histrionic and borderline traits, too, seem to be related to the presence of a cyclothymic disposition. The data overall, in particular the cyclothymic reactivity in the absence of differences in BP-I and II, all support the hypothesis that places BN in the "ultra-soft" bipolar realm.

The close link between suicide attempts and mixed (bipolar) depression: implications for suicide prevention. J Affect Disord 2006; 91:133-8. [PMID: 16458364 DOI: 10.1016/j.jad.2005.12.049] [Citation(s) in RCA: 192] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2005] [Accepted: 12/05/2005] [Indexed: 11/26/2022]
Abstract
BACKGROUND Previous reports have shown a significant relationship between suicide ideation and mixed depression. The aim of this study was to explore the prevalence and clinical characteristics of mixed depression among non-violent suicide attempters. METHODS Using a structured interview (modified Mini International Neuropsychiatric Interview) and assessing all the symptoms of 16 psychiatric diagnoses, the authors examined 100 consecutive nonviolent suicide attempters (aged 18-65) within 24 h after their attempts. Mixed depression was defined as a major depressive episode (MDE)/dysthymic disorder plus 3 or more co-occurring hypomanic symptoms, according to the definition validated by Akiskal and Benazzi [Akiskal, H.S., Benazzi, F., 2003a. Delineating depressive mixed states: Their therapeutic significance. Clin. Approaches Bipolar Disord. 2, 41-47, Akiskal, H.S., Benazzi, F., 2003b. Family history validation of the bipolar nature of depressive mixed states. J. Affect. Disord. 73, 113-122.]. RESULTS Current mixed depression was present in 63.0% in the total sample, and in 70.8% among the 89 depressive suicide attempters. Irritability, distractibility and psychomotor agitation were present in more than 90% of the subjects with mixed depression. The rate of mixed depression was significantly higher among bipolar than non-bipolar depressive suicide attempters (90% vs. 62%). Patients with mixed depression had the following concurrent disorders: bipolar disorders 41.0%, panic disorder 30.0%, generalized anxiety disorder 89.0%, alcohol abuse/dependence 56.0%, and substance abuse 27.0%. Mixed depression versus non-mixed depression had the following significant associations (odds ratio=OR): females 2.4, bipolar II disorder 9.3, generalized anxiety disorder 41.3, irritability 101.6 and psychomotor agitation 61.1. LIMITATIONS The study didn't include suicide attempters with very high risk of fatality. CONCLUSIONS The important new finding of this study is the very high prevalence of mixed depression among depressed suicide attempters. The rates of mixed depression among bipolar and non-bipolar depressive suicide attempters were much higher than previously reported among nonsuicidal bipolar II and unipolar depressive outpatients, suggesting that suicide attempters come mainly from mixed depressives with predominantly bipolar II base. Irritability and psychomotor agitation were the strongest predictors of suicide attempt. From a public health standpoint, our data highlight the necessity of detecting and treating mixed (bipolar) depression in the prevention of suicidal behaviour.

The 5HTTLPR polymorphism of the serotonin transporter gene is associated with affective temperaments as measured by TEMPS-A. J Affect Disord 2006; 91:125-31.

Abstract
BACKGROUND Increasing evidence supports the notion of a continuum between affective temperaments and major mood disorders, suggesting that these temperament types represent the subclinical manifestations of affective disorders and often present an increased vulnerability for these diseases. METHODS The Hungarian rendition of the full-scale 110-item version of the TEMPS-A questionnaire and 5HTTLPR genotype was investigated in a sample of 139 unrelated Caucasian females with no current or lifetime Axis I psychiatric disorders. RESULTS A significant association was found between the s allele and the TEMPS scores of the depressive, anxious, irritable, and particularly the cyclothymic temperaments; no such association emerged with respect to the hyperthymic temperament. LIMITATION The database is entirely female. Given that the hyperthymic type predominates in males, our results could have been different if men were included in our sample. CONCLUSIONS Our results are in good agreement with earlier studies reporting a strong association between the s allele of the 5HTTLPR and major as well as subthreshold forms of depression, and extend this association to the normative temperament level. Indeed, these temperaments might best be regarded as proximate behavioural endophenotypes. Our data raise the provocative possibility that the genetic potential for mood episodes lies in these temperaments. Further studies are needed to delineate the role of gender in the associations under consideration, as well as to investigate the genetic background of the hyperthymia-mania part of the affective spectrum. Given that affective temperaments are widely distributed in the general population, the strategy employed by us is of potential public health significance in terms of detecting individuals in the community at risk for affective spectrum disorders.

Psychometric properties of the Lebanese-Arabic TEMPS-A: a national epidemiologic study. J Affect Disord 2005; 87:169-83.

Abstract
BACKGROUND Several measures have been proposed to evaluate temperament traits and their connection to psychopathology. One recent development in this area is the TEMPS-A (Temperament Evaluation of Memphis, Pisa, Paris and San Diego Auto-questionnaire). The purpose of this study is to psychometrically validate the Lebanese-Arabic version of TEMPS-A. METHODS The TEMPS-A was adapted to Lebanese-Arabic and administered to 1320 Lebanese (593 males, 727 females, mean age of 43+/-16 years) representing the adult population of Lebanon (total population: 4.2 million). This section was added by the Institute for Development Research and Applied Care (IDRAC) to the cross-national World Mental Health (WMH) initiative Lebanese chapter. Chronbach-alpha and Pearson's correlation were used to test the internal consistency and correlation among the subscales. Factor loadings were calculated using the principal component analysis with varimax rotation. RESULTS Internal consistency varied between 0.66 (depressive) and 0.88 (anxious). As formulated by the originators of the instrument, five main factors emerged from the factor analysis, with some overlap between the depressive, the cyclothymic and the anxious temperaments, but almost none for the hyperthymic and irritable temperaments. The strongest correlation was observed between the anxious and the cyclothymic temperament subscales. Women had higher mean scores on the depressive, cyclothymic, and anxious subscales, whereas men scored higher on the hyperthymic subscale. There was a trend of increase by age in scores of the depressive subscale, and a trend of decrease in the cyclothymic and irritable subscales. CONCLUSION The Lebanese-Arabic TEMPS-A has a good internal consistency, is easy to use, and opens new and interesting research avenues in large epidemiologic national studies on temperament.

Abstract
BACKGROUND The purpose of this study was to determine the relationship between mixed states and suicidality among adolescent outpatients presenting with a DSM-IV defined major depressive episode (MDE). METHODS Two-hundred and forty-seven adolescents meeting the criteria for MDE were screened for the presence of concurrent, intra-MDE hypomania/mania (i.e., mixed states). All patients were asked whether they had current suicidal ideation or had recently attempted any self-destructive physical act associated with the thought of dying (i.e., a suicide attempt). The data were subjected to analysis using univariate logistic regression. RESULTS One hundred of the 247 (40.5%) adolescents were bipolar type I or type II. Of these, 82% were in mixed states. Of the patients with suicidal ideation, 62.8% were girls, and of those with histories of a suicide attempt, 69.4% were girls. Girls had more than twice the risk of having suicidal ideation (OR=2.2, p=0.004) and nearly 3 times the risk of having histories of a suicide attempt than boys (OR=2.87, p<0.0001). Being in a mixed state per se did not predict either suicidal ideation or a suicide attempt among all of the 247 patients. However, mixed states apparently independently contributed to the risk of (non-fatal) suicidal behavior among girls only. Of the mixed states, girls had nearly 4 times the risk of having made a suicide attempt compared with those without mixed states (OR=3.9, p=0.003). Age, presence of psychotic features and family history of mood disorder had little or no bearing on suicidality. LIMITATIONS Correlational chart review study, no data collection on Axis I and Axis II comorbidity and adverse life-events. CONCLUSIONS This report of greater suicidality in adolescent girls in a mixed state parallels the well-known adult literature of high frequency of mixed states in women. The findings are of relevance to the controversy of antidepressants and suicidality in juvenile depressives in that they identify a vulnerable group. In line with earlier suggestions by the senior author [Akiskal, H.S., 1995. Developmental pathways to bipolarity: are juvenile-onset depressions pre-bipolar? J. Am. Acad. Child Adolesc. Psych. 34, 754-763], our data highlight the public health importance of the wider recognition of bipolar mixed states in juvenile patients masquerading as unipolar depression. Finally, it appears to us that it is the failure of our formal nosology on mixed states--rather than the antidepressants per se--which is the root problem in this controversy.

The proposed factor structure of temperament and personality in Japan: combining traits from TEMPS-A and MPT. J Affect Disord 2005; 85:93-100.

Abstract
BACKGROUND In Japan, Kraepelin's descriptions on four "fundamental states" of manic depressive illness, the concepts of schizoid temperament by Kretschmer and obsessional and melancholic type temperament by Shimoda and Tellenbach have been widely accepted. This research investigates the construct validity of these temperaments through factor analysis. METHOD TEMPS-A measured depressive, cyclothymic, hyperthymic and irritable temperaments and MPT rigidity, esoteric and isolation subscales measured, respectively, melancholic type and schizoid temperaments. Factor analysis was implemented with TEMPS-A alone and TEMPS-A and MPT combined data. RESULTS With TEMPS-A alone analysis, Factor 1 included 1 depressive, 11 cyclothymic and 12 irritable temperament items with a factor loading higher than 0.4; Factor 2 included 1 depressive and 10 hyperthymic temperament items; and Factor 3 included 2 depressive temperament items only. With TEMPS-A and MPT combined data, Factor 1 included 3 depressive, 11 cyclothymic and 5 irritable temperament items with a factor loading higher than 0.4 (interpreted as the central cyclothymic tendency for all affective temperaments along Kretschmerian lines and accounting for 11.7% of the variance); Factor 2 included 6 hyperthymic temperament items (6.22% of variance); Factor 3 included 1 cyclothymic, 7 irritable and 1 schizoid temperament items (interpreted as the irritable temperament and accounting for 3.24% of the variance); Factor 4 included 1 depressive temperament and 5 melancholic type items (interpreted as the latter, accounting for 2.66% of the variance); Factor 5 included 5 depressive temperament items, along interpersonal sensitivity and passivity lines, and accounting for 2.31% of the variance; and Factor 6 included 4 schizoid temperament items accounting for 2.07% of the variance. LIMITATION We did not use the Kasahara scale, which some believe to better capture the Japanese melancholic type. Sample was 70% male. CONCLUSION These analyses confirm the factor validity of depressive, hyperthymic, cyclothymic and irritable temperaments (TEMPS-A), as well as the melancholic type and the schizoid temperament (MPT). Traits of the depressive and melancholic types emerge as rather distinct. Indeed, our results permit the delineation of an interpersonally sensitive type that "gives in to others" as the core features of the depressive temperament; this is to be contrasted with the higher functioning, perfectionistic, work-oriented melancholic type. Mood dysregulation is represented by the largest number of traits in this population. Contrary to a widely held belief that the melancholic type with its devotion to work and to others is the signature temperament in Japan, cyclothymic traits account for the largest variance in this nonclinical population. Hyperthymic temperament, melancholic type and schizoid temperaments appear largely independent of mood dysregulation. In this Japanese population, TEMPS-A may identify temperament constructs more comprehensively when implemented with melancholic type and schizoid temperament question items added to it. The proposed new Japanese Temperament and Personality (JTP) Scale has self-rated items divided into six subscales.

TEMPS-A: progress towards validation of a self-rated clinical version of the Temperament Evaluation of the Memphis, Pisa, Paris, and San Diego Autoquestionnaire. J Affect Disord 2005; 85:3-16.

Abstract
BACKGROUND Our aim was to validate the Temperament Evaluation of the Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A) in a clinical population. METHODS The study was conducted in two Memphis mood clinics involving 398 affectively ill patients with young to middle index age (42 years+/-13 S.D.), who were 95% white, 62% female, and 51% bipolar spectrum. A subset of 157 of the entire sample were retested in 6-12 months, and the entire sample was then subjected to factor analysis (PCA extraction method with varimax rotation). RESULTS We obtained high test-retest reliability ranging from 0.58 for the irritable, to 0.68, 0.69 and 0.70, respectively, for the cyclothymic, dysthymic and hyperthymic. The hypothesized four-factor structure of the TEMPS-A was upheld, with the cyclothymic explaining 14% of the variance, followed by the irritable, hyperthymic, and dysthymic together accounting for another 14%. Internal consistency was excellent, with Chronbach alphas ranging from 0.76 for the dysthymic to 0.88 for the cyclothymic. Exploratory factor analysis revealed 2 super factors, Factor I loading on cyclothymic, irritable, and dysthymic temperaments, and Factor II loading heavily on the hyperthymic. The 50-item TEMPS-A-Clinical Version was constructed by using a cutoff of alpha > or =0.4 for traits loading exclusively on their original temperaments. We also proposed a longer 69-item version for future study, in which we permitted a greater number of traits based on clinical considerations (alpha cutoff 0.30). LIMITATION The sample was preponderantly white, and may not generalize to other U.S. ethnic groups. This earlier version of TEMPS-A did not include the anxious temperament. CONCLUSIONS We psychometrically validated the TEMPS-A in affectively ill outpatients, leading to an instrument suitable for use in psychiatric, especially affectively ill, populations. It is noteworthy that in this clinically ill population we succeeded in measuring traits which could make subjects vulnerable to affective episodes, as well as those of adaptive nature. For instance, the dysthymic emerged as bound to routine, self-blaming, shy-nonassertive, sensitive to criticism, yet self-denying, dependable, and preferring to work for someone else rather than be the boss. The hyperthymic had the highest number of "positive" traits: upbeat, fun-loving, outgoing, jocular, optimistic, confident, full of ideas, eloquent, on the go, short-sleeper, tireless, who likes to be the boss, but single-minded, risk-taker, and unlikely to admit to his/her meddlesome nature. The cyclothymic emerged as labile with rapid shifts in mood; unstable in energy, self-esteem and socialization; unevenly gifted and dilettante; yet keen in perception, intense in emotions, and romantic. The irritable emerged as skeptical and critical (which might be considered intellectual virtues), but otherwise having the "darkest" nature of all temperaments: grouchy, complaining, dissatisfied; anger- and violence-prone, and sexually jealous. The foregoing temperament attributes, observed in a moderately severe group of patients with affective disorders, nonetheless testify to the evolutionary context of these disorders-"submissive" behavior, territoriality, romantic charm, and last, but not least, sexually jealous with its associated specter of violence. We hypothesize that the putative social and limbic mechanisms underlying mood disorders appear to have archaic origins on an evolutionary scale. We finally submit that the traits underlying affective disorders are very much part of human nature.

Reliability and validity of TEMPS-A in a Japanese non-clinical population: application to unipolar and bipolar depressives. J Affect Disord 2005; 85:85-92.

Abstract
BACKGROUND In Japan, TEMPS-A has gathered much attention, because Kraepelin's concepts on "fundamental states" of mood disorder and temperaments have been widely respected. METHOD TEMPS-A was translated into Japanese (and after the approval of the English back translation by H.S.A.), it was administered to 1391 non-clinical subjects, and 29 unipolar and 30 bipolar patients in remission. Of the non-clinical sample, 426 were readministered the instrument again in 1 month. A control group matched for gender and age was drawn from the non-clinical sample. RESULTS Regarding test-retest reliability, Spearman's coefficients for depressive, cyclothymic, hyperthymic, irritable and anxious temperaments were 0.79, 0.84, 0.87, 0.81 and 0.87, respectively; regarding internal consistency, Cronbach's alpha coefficients were 0.69, 0.84, 0.79, 0.83 and 0.87, respectively. The unipolar and bipolar groups showed significantly higher depressive, cyclothymic and anxious temperament scores than the control group. Curiously, the bipolar group showed significantly lower hyperthymic score than the control group; irritable temperament scores showed no significant differences. Depressive, cyclothymic, irritable and anxious temperament scores showed significant correlations with each other. Between the unipolar and bipolar groups, there was little difference regarding the temperament scores. Also the inter-temperament correlations showed the same pattern in the unipolar and bipolar groups. LIMITATION The clinically well cohort was 70% male. CONCLUSION TEMPS-A showed a high reliability and validity (internal consistency) in a Japanese non-clinical sample. By and large, the hypothesized five temperament structure was upheld. Depressive, cyclothymic and anxious temperaments showed concurrent validity with mood disorder. Irritable temperament may represent a subtype of depressive, cyclothymic or anxious temperaments. There may be a temperamental commonality between unipolar and bipolar disorders. TEMPS-A will open new possibilities for international research on mood disorder and personality traits.

The theoretical underpinnings of affective temperaments: implications for evolutionary foundations of bipolar disorder and human nature. J Affect Disord 2005; 85:231-9.

Abstract
We sketch out putative evolutionary roles for affective temperaments within the theoretical framework of mood disorders conceptualized as extremes in an oligogenic model of inheritance, whereby the constituent traits in their dilute phenotypes confer adaptive advantages to individuals and/or their social group. Depressive traits, among other functions, would subserve sensitivity to the suffering of other members of the species, overlapping with those of the generalized anxious temperament, thereby enhancing the survival of not only kin but also other conspecifics. The pursuit of romantic opportunities in cyclothymia suggests that it may have evolved as a mechanism in reproductive success; cyclothymics' creative bent in poetry, music, painting, cooking or fashion design (among men, in particular) also appears useful for sexual seduction. Hyperthymic traits would lend distinct advantages in leadership, exploration, territoriality and mating. These are just some of the possibilities of the rich and complex temperamental traits subserving bipolarity within an evolutionary framework. We test selected aspects of these hypotheses with the use of correlations between the constituent traits of the Temperament Evaluation of Memphis, Pisa, Paris and San Diego (TEMPS) and correlations between the TEMPS and the Temperament and Character Inventory (TCI). Such data support the counterbalancing protective influence of harm avoidance on the risk-taking behavior of cyclothymic individuals, in both men and women. Finally, we outline a hypothesis on the evolutionary function of anxious-depressive traits for women.
