Abstract
ABSTRACT Adult attention-deficit disorder (ADD) is a common diagnosis, and amphetamine medications are increasingly used. Recent reports suggest high prevalence of affective temperaments, such as cyclothymia, in adult ADD. This study reexamines prevalence rates as reflecting misdiagnosis and reports for the first time on the effects of amphetamine medications on mood/anxiety and cognition in relation to affective temperaments. Among outpatients treated at the Tufts Medical Center Mood Disorders Program (2008-2017), 87 cases treated with amphetamines were identified, versus 163 non-amphetamine-treated control subjects. Using the Temperament Scale of Memphis, Pisa, Paris and San Diego-Autoquestionnaire, 62% had an affective temperament, most commonly cyclothymia (42%). In amphetamine-treated cases, mood/anxiety symptoms worsened notably in 27% ( vs. 4% in the control group, risk ratio [RR] 6.2, confidence interval [CI], 2.8-13.8), whereas 24% had moderate improvement in cognition ( vs. 6% in the control group; RR, 3.93; CI, 1.9-8.0). Affective temperaments, especially cyclothymia, are present in persons about one-half of persons diagnosed with adult ADD and/or treated with amphetamines.

Behavioral activation system (BAS) dysregulation and bipolar spectrum psychopathology in daily life: An online-diary study. Psychiatry Res 2020; 291:113180. [PMID: 32544707 DOI: 10.1016/j.psychres.2020.113180] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/27/2020] [Revised: 05/31/2020] [Accepted: 06/01/2020] [Indexed: 01/15/2023]
Abstract
Dysregulation of the behavioral activation system (BAS) has been theorized to be a core factor underlying mood swings in bipolar disorder (BD). However, few studies have directly addressed BAS dysregulation and more research is needed to understand its dynamic expression in daily life. The aim of this study was to directly assess BAS dysregulation, and to examine its moderating effect on the relationship between life events and bipolar spectrum symptoms via multilevel modeling. Korean young adults (n = 100) were screened using the Hypomanic Personality Scale (HPS) from a large sample (N = 1,591). They completed online diaries for 7 consecutive days including the Daily Events Record as well as bipolar spectrum symptoms. BAS-activating and/or -deactivating scores were allocated to each reported life event by an expert consensus rating. Cross-level interaction analysis showed that the occurrence of BA life events contributed to a steeper increase in bipolar spectrum symptoms, particularly for individuals with high BAS dysregulation. The present study suggests that BAS dysregulation is a unique construct that deserves further exploration in BD.

Does temperamental instability support a continuity between bipolar II disorder and major depressive disorder? Eur Psychiatry 2020; 21:274-9. [PMID: 16675205 DOI: 10.1016/j.eurpsy.2006.02.003] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2005] [Revised: 02/11/2006] [Accepted: 02/15/2006] [Indexed: 10/24/2022] Open
Abstract
AbstractBackgroundThe current categorical split of mood disorders in bipolar disorders and depressive disorders has recently been questioned. Two highly unstable personality features, i.e. the cyclothymic temperament (CT) and borderline personality disorder (BPD), have been found to be more common in bipolar II (BP-II) disorder than in major depressive disorder (MDD). According to Kraepelin, temperamental instability was the ‘foundation’ of his unitary view of mood disorders.Study aimThe aim was to assess the distributions of the number of CT and borderline personality items between BP-II and MDD. Finding no bi-modal distribution (a ‘zone of rarity’) of these items would support a continuity between the two disorders.MethodsStudy setting: an outpatient psychiatry private practice. Interviewer: A senior clinical and mood disorder research psychiatrist. Patient population: A consecutive sample of 138 BP-II and 71 MDD remitted outpatients. Assessment instruments: The structured clinical interview for DSM-IV Axis I Disorders-Clinician Version (SCID-CV), the SCID-II Personality Questionnaire for self-assessing borderline personality traits (BPT) by patients, the TEMPS-A for self-assessing CT by patients. Interview methods: Patients were interviewed with the SCID-CV to diagnose BP-II and MDD, and then patients self-assessed the questions of the Personality Questionnaire relative to borderline personality, and the questions of the TEMPS-A relative to CT. As clinically significant distress or impairment of functioning is not assessed by the SCID-II Personality Questionnaire, a diagnosis of BPD could not be made, but BPT could be assessed (i.e. all BPD items but not the impairment criterion). The distribution of the number of CT and BPT items was studied by Kernel density estimate.ResultsCT and BPT items were significantly more common in BP-II versus MDD. The Kernel density estimate distributions of the number of CT and BPT items in the entire sample had a normal-like shape (i.e. no bi-modality).ConclusionsThe expected finding, on the basis of previous studies and of the present sample features, was a clustering of CT and BPT items on the BP-II side of the curves. Instead, no bi-modality was present in the distributions of the number of CT and BPT items in the entire sample, showing a normal-like shape. By using the bi-modality approach, a continuity between BP-II and MDD seems supported, questioning the current categorical splitting of BP-II and MDD based on classic diagnostic validators.

Abstract
AbstractBipolar disorders are frequently not diagnosed until long after their onset, leaving patients with no or correspondingly inadequate treatment. The course of the disorder is all the more severe and the negative repercussions for those affected all the greater. Concerted research effort is therefore going into learning how to recognize bipolar disorders at an early stage. Drawing on current research results, this paper presents considerations for an integrative Early Symptom Scale with which persons at risk can be identified and timely intervention initiated. This will require prospective studies to determine the predictive power of the risk factors integrated into the scale.

Prepulse inhibition in patients with bipolar disorder: a systematic review and meta-analysis. BMC Psychiatry 2019; 19:282. [PMID: 31510965 PMCID: PMC6737635 DOI: 10.1186/s12888-019-2271-8] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2018] [Accepted: 09/03/2019] [Indexed: 12/03/2022] Open
Abstract
BACKGROUND Prepulse inhibition (PPI) is a measurement method for the sensory gating process, which helps the brain adapt to complex environments. PPI may be reduced in patients with bipolar disorder (BD). This study investigated PPI deficits in BD and pooled the effect size of PPI in patients with BD. METHODS We conducted a literature search on PPI in patients with BD from inception to July 27, 2019 in PubMed, Embase, Cochrane Library databases, and Chinese databases. No age, sex, and language restriction were set. The calculation formula was PPI = 100 - [100*((prepulse - pulse amplitude) / pulse amplitude)]. The Newcastle-Ottawa Scale (NOS) was used to assess the quality of studies. RESULTS Ten eligible papers were identified, of which five studies including a total of 141 euthymic patients and 132 healthy controls (HC) were included in the meta-analysis. Compared with HC, euthymic patients with BD had significantly lower PPI at the 60 ms interstimulus interval (ISI) between pulse and prepulse (P = 0.476, I2 = 0.0%, SMD = - 0.32, 95% CI = - 0.54 - -0.10). Sensitivity analysis shows no significant change in the combined effect value after removing any single study. There was no publication bias using the Egger's test at 60 ms (P = 0.606). The meta-analysis of PPI at the 60 ms ISI could have significant clinical heterogeneity in mood episode state, as well as lack of data on BD I or II subtypes. CONCLUSIONS Euthymic patients with BD show PPI deficits at the 60 ms, suggesting a deficit in the early sensory gate underlying PPI. The PPI inhibition rate at a 60 ms interval is a stable index. More research is needed in the future to confirm this outcome, and to delve deeper into the mechanisms behind deficits.

Factorial structure and familial aggregation of the Hypomania Checklist-32 (HCL-32): Results of the NIMH Family Study of Affective Spectrum Disorders. Compr Psychiatry 2018; 84:7-14. [PMID: 29655654 PMCID: PMC6002901 DOI: 10.1016/j.comppsych.2018.03.010] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2017] [Revised: 03/15/2018] [Accepted: 03/23/2018] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND There is substantial evidence that bipolar disorder (BD) manifests on a spectrum rather than as a categorical condition. Detection of people with subthreshold manifestations of BD is therefore important. The Hypomania Checklist-32 (HCL-32) was developed as a tool to identify such people. PURPOSE The aims of this paper were to: (1) investigate the factor structure of HCL-32; (2) determine whether the HCL-32 can discriminate between mood disorder subtypes; and (3) assess the familial aggregation and cross-aggregation of hypomanic symptoms assessed on the HCL with BD. PROCEDURES Ninety-six probands recruited from the community and 154 of their adult first-degree relatives completed the HCL-32. Diagnosis was based on semi-structured interviews and family history reports. Explanatory factor analysis and mixed effects linear regression models were used. FINDINGS A four-factor ("Activity/Increased energy," "Distractibility/Irritability", "Novelty seeking/Disinhibition, "Substance use") solution fit the HCL-32, explaining 11.1% of the total variance. The Distractibility/Irritability score was elevated among those with BP-I and BP-II, compared to those with depression and no mood disorders. Higher HCL-32 scores were associated with increased risk of BD-I (OR = 1.22, 95%CI 1.14-1.30). The "Distractibility/Irritability" score was transmitted within families (β = 0.15, p = 0.040). However, there was no familial cross-aggregation between mood disorders and the 4 HCL factors. CONCLUSIONS Our findings suggest that the HCL-32 discriminates the mood disorder subtypes, is familial and may provide a dimensional index of propensity to BD. Future studies should explore the heritability of symptoms, rather than focusing on diagnoses.

Abstract
BACKGROUND Bipolar disorder (BD) is often misdiagnosed as major depressive disorder (MDD). This study tested the psychometric properties and the accuracy of the Chinese version of the 33-item Hypomania Checklist (HCL-33) to identify BD in Chinese clinical settings. METHODS A total of 350 depressed patients were consecutively interviewed in a major psychiatric hospital in China. The patients' socio-demographic and clinical characteristics were recorded using standardized protocol and data collection procedures. The HCL-33 was completed by patients to detect symptoms characteristic of mania and hypomania. DSM-IV diagnoses were established using the Mini International Neuropsychiatric Interview (MINI). RESULTS The HCL-33 showed high internal consistency with two-factorial dimensions. The optimal cut-off point on the HCL-33 to differentiate BD from MDD was 15, while cut-off points of 14 and 13 differentiated BD-I and BD-II from MDD, respectively. The maximum sensitivity was 0.62, 0.67 and 0.72 for differentiating BD, BD-I and BD-II from MDD, respectively. CONCLUSIONS The HCL-33 is a useful tool for screening for BD in Chinese depressed patients. The routine clinical use of the HCL-33 as a screening instrument for BD in Chinese patients is recommended.

Abstract
Seventy male patients with non-psychotic mental disorders of youthful age (mean age 19.2±3.7), were studied using A.R. Luria neuropsychological syndrome analysis. Patients were stratified into 3 groups by diagnosis: cyclothymia (20 patients), pubertal decompensation of schizoid personality disorder (30 patients) and schizotypal personality disorder (20 patients). It has been shown that the neuropsychological changes indicate the dysfunction of the amygdale/temporal region in patients of the first group and frontal/thalamic/parietal connections in the patients of two other groups. There were interhemispheric differences between patients with personality disorder and schizotypal personality disorder: left hemisphere dysfunction was characteristic of schizotypal disorder and right hemisphere deficit (neurocognitive deficit) was found in patients with personality disorder.

The association of affective temperaments with impairment and psychopathology in a young adult sample. J Affect Disord 2012; 141:373-81.

Abstract
BACKGROUND Previous research has examined the association of affective temperaments, as measured by the TEMPS-A, with DSM bipolar disorders. However, the relation of the TEMPS-A with risk for bipolar disorder remains unclear. The present study examined the association of affective temperaments with psychopathology, personality, and functioning in a nonclinically ascertained sample of young adults at risk for bipolar disorder. METHODS One hundred forty-five participants completed the TEMPS-A, as well as interview and questionnaire measures of psychopathology, personality, and functioning. RESULTS Cyclothymic/irritable temperament was associated with a range of deleterious outcomes, including mood disorders and impaired functioning. It was negatively associated with agreeableness and conscientiousness, and positively associated with current depressive symptoms, neuroticism, borderline symptoms, impulsivity, and grandiosity. Dysthymic temperament was positively associated with current depressive symptoms, neuroticism and agreeableness, but was unrelated to mood psychopathology. Hyperthymic temperament was associated with bipolar spectrum disorders, hypomania or interview-rated hyperthymia, extraversion, openness, impulsivity, and grandiosity. LIMITATIONS The present study was cross-sectional. Longitudinal studies utilizing the TEMPS-A are needed to better understand the predictive validity of the TEMPS-A for the development of bipolar disorder. CONCLUSIONS Early identification of individuals who fall on the bipolar spectrum may hasten appropriate intervention or monitoring, and prevent misdiagnosis. The TEMPS-A appears to be a useful tool for assessing affective temperaments and bipolar spectrum psychopathology. The results support previous research documenting the association of cyclothymic/irritable temperament with bipolar psychopathology and other negative outcomes.

Clinical configuration of cyclothymic disturbances. J Affect Disord 2012; 139:244-9.

Abstract
OBJECTIVE While there is an increasing recognition of the role of subthreshold symptomatology in bipolar disorder, little attention has been dedicated to its only formally acknowledged subtype, cyclothymic disorder. The aim of this investigation was to provide a controlled evaluation of DSM-IV cyclothymic disorder by using a broad assessment strategy geared to subclinical signs. METHODS Sixty-two patients who met the DSM-IV criteria for cyclothymic disorder and did not present comorbidity with other mood disorders, alcohol and drug abuse, and borderline personality disorder and 62 control subjects matched for sociodemographic variables were administered the Structured Interview for Diagnostic Criteria for Psychosomatic Research (DCPR), the Clinical Interview for Depression (CID) and the Mania Scale (MAS). RESULTS In DSM-IV terms, there was an overlap with anxiety disorders in more than half of the cases. About 3 patients out of 4 were found to present with at least one DCPR syndrome (particularly demoralization and irritable mood). Cyclothymic patients displayed significantly higher levels of depressive and anxiety disturbances on the CID, with particular reference to reactivity to social environment. They also had significantly higher scores on the MAS. LIMITATIONS The study was cross-sectional and the sample, because of the exclusion criteria, may not be representative of the clinical populations in psychiatric settings. CONCLUSION In our patients with cyclothymia, without comorbidity with major mood disorders, DSM-IV anxiety disorders, psychosomatic clinical syndromes (irritable mood, demoralization) and subclinical symptoms such as reactivity to social environment resulted to be more frequent than in controls. The use of a broad assessment strategy aimed at subclinical symptomatology may help identifying clinical phenomena that cut across the current definition of subthreshold forms of bipolar disorder.

Association between cyclothymic temperament and clinical predictors of bipolarity in recurrent depressive patients. J Affect Disord 2011; 132:285-8.

Abstract
BACKGROUND Recent studies have suggested that clinicians may under diagnose bipolarity in a substantial proportion of depressive patients, and proposed that affective temperaments particularly cyclothymic temperament (CT), may predict bipolarity in these patients. The objectives of this study were to assess CT in patients with recurrent depressive disorder (RDD) and to explore its associations with clinical predictors of bipolarity. METHODS 98 patients (43 men and 55 women, mean age=46.8±9.9years), followed for RDD according to DSM-IV-TR criteria, were recruited. CT was assessed using the Tunisian version of the TEMPS cyclothymic subscale with the threshold score of 10/21. RESULTS The mean score of CT was 6.5±5.2. One-third of patients (33.7%) had a CT score ≥10. These patients with high CT scores had significantly early age at onset of first depressive episode and high number of previous depressive episodes, and had more psychotic and melancholic features and suicidal ideations and attempts during the last depressive episode compared to patients with low CT scores. The multiple regression analysis showed an association between CT scores and psychotic, melancholic and atypical features and suicide attempts during the last depressive episode. LIMITATIONS This is a cross-sectional study with a relatively small number of patients. The Tunisian version of the CT subscale was not yet validated. CONCLUSIONS CT was associated with some clinical predictive factors of bipolarity. These results suggest the relevance of the CT screening in RDD, considering the change of polarity risk and misdiagnosis of unipolar depression.

Abstract
In the history of the nosographies in psychiatry, the affective disorders were gradually distinguished from the other categories of mental disorders, until being considered as separate illness entities, such as what Kraepelin named manic-depressive insanity at the end of the 19th century. The latter will be subsequently divided in two main categories, the bipolar disorder on the one hand and recurrent depression on the other hand, this separation being still current, and extensively diffused by the mean of the Diagnostic and Statistical Manual of Mental Disorders (DSM). The DSM, whose revisions largely determine the evolution of the contemporary nosographic models, mainly relies on a categorical approach of the mental disorders. The next revision will probably continue to follow this kind of approach, even if the use of dimensional components could also be developed. In the future, true nosographic advances can be waited from clinical epidemiology studies, as those which recently made it possible to highlight various sub-types of affective disorders on the basis of clinical, biographical or temperamental characteristics. Etiological approaches, centered on the pathophysiology of the affective disorders, could also contribute to build nosographic models on the basis of an objective knowledge on these diseases.

Abstract
BACKGROUND there is a public health issue regarding the correct diagnosis of BSD: these diseases are often underreferred, underdiagnosed and undertreated/mistreated. To fail to treat BSD may result in serious complications (loss of work, relationship crisis, substance-abuse, suicide, rapes, etc). In order to correctly diagnose Bipolar Spectrum Mood Disorders, it is important to know the patient's premorbid personality and past history: it is essential to know the longitudinal history and the full family history. METHODS 423 patients, who were recruited and assessed over six years have been reassessed to demonstrate their temperaments, as these emerge from their personal anamnesis. RESULTS more patients within the series appear to have a soft bipolar illness than a major unipolar depression; the depressive episodes are now considered as only one phase of the bipolar spectrum. Furthermore, every patient with bipolar spectrum disorder already presented in their personal history of the illness a sub-clinical evidence of one of the temperaments (hyperthymic temper.: 35%; cyclothymic temper.: 49%; depressive temper.: 16%). DISCUSSION the different temperaments are described, and their significance elucidated. CONCLUSIONS the subthreshold presence of the temperaments in the history of the patients with bipolar spectrum disorders leads us to consider this to be an important method of early diagnosis of bipolar spectrum mood disorders.

Abstract
OBJECTIVE Most research on the symptomatic burden in bipolar disorder has included patients enrolled exclusively from tertiary centers, and only a few studies have analyzed factors related to it. We investigated the proportion of time and the proportion of visits with symptoms in a cohort of bipolar outpatients followed-up for 18 months, as well as the associated variables. METHODS 296 DSM-IV-TR bipolar outpatients were included in a naturalistic longitudinal follow-up study, with quarterly assessment. Euthymia was defined by a Hamilton Depression Rating Scale score <7 and Young Mania Rating Scale score <5. Depressive episode, by a HDRS score of >17, hypomanic episode by a YMRS score of 10-20, and manic episode by a YMRS score >20. Sub-syndromal symptoms required scores of 7-17 in HDRS and 5-10 in YMRS. Based on a detailed recall of affective symptoms in the time between interviews, time in episode was also determined. RESULTS Patients were symptomatic for one third of the follow-up, and also one third of the visits. They spent three times more days depressed than manic or hypomanic. More prior affective episodes were related both to more time symptomatic and more visits with symptoms. LIMITATIONS Some of the data were collected retrospectively. Treatment was naturalistic. CONCLUSIONS In a bipolar outpatient cohort from Spain, time with symptoms was shorter than previously found in tertiary care settings. In accordance with other longitudinal studies, those patients spent much more time depressed than manic.

Abstract
BACKGROUND Studies on self-representation in bipolar disorder have mainly focused on the single dimension of self-esteem and recruited patients either in episode or in remission. The aim of the study was to examine multi-dimensional aspects of the self (discrepancy between actual- and ideal-selves and between actual- and feared-selves) in a student sample with a history of significant experience of hypomania (with or without experience of major depression) as compared to healthy control students. METHODS Bipolar students and healthy control students completed the Self-Discrepancy Questionnaire (SDQ: Carver, Lawrence, & Scheier, 1999). The degree of similarity to, and the perceived likelihood of ideal-self and feared-self characteristics were assessed. RESULTS The difference between the groups in level of ideal-self similarity was at trend level. Students with prior hypomania but no history of depression showed higher similarity to their feared-self than healthy controls and also rated themselves as more likely to have these feared-self characteristics in the future. LIMITATION The small sample size, especially in the bipolar group with no history of depression, limits the power of the study. CONCLUSIONS The presence of ideal-self discrepancy was not convincingly demonstrated in this sample and it is possible that where it has been identified in previous studies it may, at least in part, represent a scar of previous episodes of depression or mania rather than a predisposing factor. However a sub-sample of students who had experienced hypomania in the absence of history of depression were distinguished from healthy controls in perceived closeness to the feared-self qualities. The feared-self concept warrants further investigation in bipolar patients.

Building on previous work we examine the relevance of affective temperament measures in these patients. METHODS 59 consecutive stabilized methadone treated heroin addicts, 34 with and 25 without psychiatric comorbidity, were compared, regarding affective temperaments, according to the Akiskal and Mallya formulation, with 58 healthy volunteers sharing similar social and regional demographics. RESULTS No differences were observed between heroin addicts and controls on either depressive or hyperthymic scales. Significant discrepancies were noted in cyclothymic and irritability scales, on which heroin addicts scored higher, regardless of the presence or absence of a dual diagnosis. In a multivariate discriminant analysis, mainly cyclothymic, and (to a lesser extent) irritable traits show a distinction between heroin addicts and controls, but not between heroin addicts with and without dual diagnoses. LIMITATION Cross-sectional study. CONCLUSION Our data suggest a new hypothesis. Cyclothymic, and to a lesser extent irritable traits (the "dark side"), could represent the temperamental profile of heroin addicts, largely irrespective of comorbidity, and tend to cohere with previous conceptualizations hypothesizing "sensation-seeking" (and "novelty-seeking") as the main personality characteristics of addiction.

Abstract
Trichotillomania an impulse disorder that causes people to pull out the hair) is a relatively rare psychiatric illness, though the number of patients in need are definitely much higher than that we encounter in psychiatric practice. According to ICD-10 and DSM-IV-TR trichotillomania is an impulse disorder but latest researches in neurobiology and picture taking procedures seem to provide convincing evidence of it's being a relative of addictions. The article is a glimpse into the core of the newest literature also focusing on therapeutical solutions. The therapeutical effects of mode stabilizers as lamotrigine appear to gain on significance in the treatment of compulsive-impulsive illnesses such as trichotillomania. The article points out the especially high comorbidity with depression and dysthymia (OCD) and focuses on the psychopathologic impact of early traumas. In the case study many elements of the complex therapy of trichotillomania are also displayed.

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).

Heritability of bipolar spectrum disorders. Unity or heterogeneity? J Affect Disord 2008; 106:229-40.

Abstract
BACKGROUND The purpose of this study was to investigate whether the three disorders in the bipolar spectrum, Bipolar I disorder, Bipolar II disorder and Cyclothymia, are various expressions of an underlying genetic commonality. METHOD A sample consisting of same-sexed mono (MZ)- and dizygotic (DZ) twins were identified using hospital and outpatient registers (N=303). DSM-III-R criteria were assessed by personal interviews. Cross tabulations were used to compare concordance rates for different definitions of the bipolar spectrum. Correlations in liability and estimation of the heritability (h) with biometrical model fitting were performed. RESULTS Concordance rates were higher among MZ- than DZ pairs for all the single diagnoses and main combinations of diagnoses. Cross-concordance between different diagnoses was observed. The heritability of Bipolar I was .73, of Bipolar I+II .77 and of Bipolar I+II+Cyclothymia .71. LIMITATION Probands were not sampled from the general population. Most often the same person interviewed both twins in a pair. The statistical power was restricted in some sub-analyses. CONCLUSION The 'Bipolar Spectrum' category consisting of Bipolar I disorder, Bipolar II disorder and Cyclothymia constitute one entity with high heritability without detectable shared family environmental effects. Future genetic and clinical work might consider that all variants of the bipolar spectrum are an expression of one underlying genetic liability.

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.

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].

Cocaine abuse and the bipolar spectrum in 1090 heroin addicts: clinical observations and a proposed pathophysiologic model. J Affect Disord 2008; 106:55-61. [PMID: 17669508 DOI: 10.1016/j.jad.2007.03.015] [Citation(s) in RCA: 26] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2006] [Accepted: 03/05/2007] [Indexed: 11/22/2022]
Abstract
BACKGROUND Several studies indicate a specific relationship between bipolar disorder and stimulant use and abuse. It has generally been assumed that cocaine use represents self-enhancement or attempts to optimize one's level of hypomania, cyclothymia or hyperthymia. This topic required further examination among heroin abusers because cocaine abuse is commonly comorbid with heroin abuse. METHODS Cocaine abuse by bipolar subjects was investigated in a group of 1090 treatment-seeking heroin addicts enrolled between 1994 and 2005. We collected data with 1) the Drug Addiction History Rating Scale; and 2) the Semi-structured Interview for Depression, which inquires systematically among others, about hypomania, cyclothymia, hyperthymia and depressive temperament. Subjects were aged 29+/-6 years, and predominantly male (76.2%). RESULTS Univariate and multivariate analyses provided correlations in favour of a link between current cocaine abuse and double diagnosis, with special relevance to the bipolar spectrum, as well as psychotic disorders (p<0.0001). LIMITATION The modality of access to cocaine in different communities and the difficulty to distinguish cocaine use from abuse by the rating scale administered may have limited the interpretation of results. CONCLUSIONS If cocaine abuse precedes that of heroin or is concomitant, heroin may hypothetically serve as a "mood balancer" which transiently dampens subthreshold excitatory states and mood swings. Our data further suggest the need for a more complex model linking cocaine and bipolarity: subthreshold bipolarity, including hyperthymic and cyclothymic temperaments, seems to predispose to heroin addiction, but craving for the suppressed hypomania in turn could lead to cocaine abuse, which eventually unmasks a frank bipolar disorder - in some cases leading to mixed state, severe mania, as well as psychosis beyond mania. Prospective observations would shed further insight on this complex interface of major clinical and public health importance.

Abstract
This article examines how bipolar symptoms emerge during development, and the potential role of psychosocial and pharmacological interventions in the prevention of the onset of the disorder. Early signs of bipolarity can be observed among children of bipolar parents and often take the form of subsyndromal presentations (e.g., mood lability, episodic elation or irritability, depression, inattention, and psychosocial impairment). However, many of these early presentations are diagnostically nonspecific. The few studies that have followed at-risk youth into adulthood find developmental discontinuities from childhood to adulthood. Biological markers (e.g., amygdalar volume) may ultimately increase our accuracy in identifying children who later develop bipolar I disorder, but few such markers have been identified. Stress, in the form of childhood adversity or highly conflictual families, is not a diagnostically specific causal agent but does place genetically and biologically vulnerable individuals at risk for a more pernicious course of illness. A preventative family-focused treatment for children with (a) at least one first-degree relative with bipolar disorder and (b) subsyndromal signs of bipolar disorder is described. This model attempts to address the multiple interactions of psychosocial and biological risk factors in the onset and course of bipolar disorder.

Abstract
OBJECTIVE The purpose of this brief report is to describe the comorbid diagnoses and high-risk behaviors in a sample of adolescents with bulimia nervosa (BN). METHOD Eighty adolescents enrolled in a RCT for BN that compared family-based therapy with individual-supportive psychotherapy completed the Eating Disorder Examination and the Schedule for Affective Disorder and Schizophrenia for School Age Children (K-SADS). RESULTS A total of 62.5% of the sample had a comorbid diagnosis as determined by the K-SADS. The majority of these presented with a major mood disorder. In addition, 25% of the sample had previously attempted suicide or self-harmed, 65.8% had consumed alcohol, and 30% had used illegal drugs. Suicidal behavior, drug use, and presence of a comorbid diagnosis were not related to diagnosis (full BN vs. subthreshold BN) or age. CONCLUSION Comorbidity and high-risk health behaviors in adolescents with BN mirror those of adults with BN although not at similar rates.

Abstract
An audit of the diagnosis of 300 consecutive new cases presenting in a private practice over the period of the last four years (from January 2003 to December 2006) is presented. The main observation is the high percentage of patients who fall within the bipolar spectrum who are diagnosed and reported. In particular, there is a large proportion of patients who suffer from Bipolar II illness. The consequences of this in the diagnosis and management of patients is discussed.

Abstract
The importance of observing swings above euthymic normality in patients with affective disorders has been emphasized by many research groups. The concept of mood bipolarity has not only established a Bipolar II disorder (with only hypomania, not mania, but also opened up for discussion of a Bipolar Spectrum, that would necessitate treatment with a broader range of agents, i.e., not only antidepressants. In order to understand the determinants of the patterns of mood swings in individuals with bipolar disorder we have used a computerized life-charting technique to analyze a large amount of clinical information in 100 patients with bipolar mood swings. In a cross-sectional set-up, we demonstrate clear evidence of achieving a better long-term stabilization when starting patients on mood stabilizer early after the first evidence of the mood disorder.

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
BACKGROUND Historically, cyclothymia has been used broadly to refer either to a temperament (Kretschmer) or the entire range of bipolar disorders. Within this spectrum, it is uncertain whether it characterizes the "hard" (or manic-depressive) forms (as Kurt Schneider argued) or its "soft" expressions (bipolar II and highly recurrent depressions); the latter perspective is in line with Falret's view that the melancholic expressions of his folie circulaire (circular insanity) were highly prevalent in the community. METHODS Eight hundred forty-three outpatients were interviewed with the Schedule for Affective Disorders and Schizophrenia without regard to hierarchical exclusionary rules. RESULTS Compared to 630 psychiatrically interviewed outpatients who did not have cyclothymia, 163 cyclothymics were significantly more likely to have most of the disorders listed in the SADS in univariate analyses. Discriminant analyses limited the significant associations to labile personality, bipolar II, intermittent depression, secondary depression, hypomanic disorder and schizoaffective mania. LIMITATION The RDC construct of cyclothymia is rather broad. CONCLUSIONS Despite such operational breadth, cyclothymia was nonetheless largely limited to the soft end of the bipolar spectrum where labile moods and depressive recurrence predominate. In this sense, it is natural to place it on the border of manic-depressive psychosis. Although Kurt Schneider was the first to describe the "labile psychopath" [personality], he believed it was unrelated to his narrow concept of cyclothymia, which he used synonymously with manic-depressive psychosis. Our data do not support his position. Instead, they support both Kretchmer's and Falret's views.

Abstract
BACKGROUND Whereas a growing body of evidence suggests that cycloid psychoses have to be separated from schizophrenic psychoses, their relations to bipolar affective disorder are less clear. PATIENTS AND METHODS In a controlled family study, we recruited 46 patients with cycloid psychosis (CP), 33 with manic-depressive illness (MDI), and 27 controls. Three hundred fifty-six of 389 living first-degree relatives were personally examined by experienced psychiatrists blinded to the diagnosis of the index proband. RESULTS The relatives of CP patients showed significantly lower morbidity risk of functional psychoses than relatives of patients with MDI in Kaplan-Meier life table calculation. The morbidity risk for functional psychoses in relatives of patients with CP did not differ significantly from that in relatives of controls. CONCLUSION These results suggest that CP are etiologically different from bipolar affective psychoses and cannot be integrated into the spectrum of bipolar affective disorders. The findings provide further evidence for a nosological independence of CP.

Abstract
BACKGROUND Correct diagnosis and criteria of affective disorders is always a subject of interest to researchers and practitioners. METHODS The study aimed at assessing frequency of various traits and symptoms of bipolar affective disorders (BP-I, BP-II, BP-S spectrum) in patients (n=246) treated for recurrent affective disorders (unipolar-UP). The analysis was based on criteria of affective disorders of Ghaemi et al. and Hirschfeld's Mood Disorders Questionnaire. RESULTS UP was confirmed in 32.9% of individuals, whereas 19.5% were BP-I, 35% BP-II and 12.6% BP-S. UP patients were significantly more often professionally active than those with BP (37.2% vs. 22.7%). Duration of a disorder was significantly shorter and the number of depressive episodes lower in the UP group. In comparison with UP, BP-I were associated with the previous occurrence of unusual and/or risky behaviour (OR=24.5), excessive, irrational expenditure (OR=21.1), lack of a critical attitude with respect to social behaviour (OR=20.3), increased sex drive (OR=17.7), and excessive self-confidence (OR=12). BP-II were associated with a lack of criticism with regard to social behaviour (OR=12.7) and unusual and/or risky behaviour (OR=10). Spectrum BP were most strongly associated with short term hypomanic episodes, including drug induced episodes (OR=15.8) and lack of criticism (OR=11.8). Early onset of depression (before 25 years of age) increased the risk of all three types of BP (by a factor of 3 to 5). LIMITATIONS This was a naturalistic study, in which treatment was uncontrolled. CONCLUSIONS Results of the study are a voice in the discussion on too narrow criteria defining bipolar affective disorders.

Abstract
Bipolar spectrum disorders and addiction often co-occur and constitute reciprocal risk factors that the authors believe are best considered under a unitary perspective. In particular, we submit that patients whose disorders fall under the bipolar spectrum - and its hyperthymic and cyclothymic temperamental substrates are at increased risk for substance use, possibly moving towards addiction through exposure to intrinsically dependence-producing substances. In our experience, the contribution of bipolar spectrum disorders to the addictive process is often clinically missed, because attenuated and subclinical expressions of such mood disorders as bipolar II and cyclothymia are not adequately appreciated by our current formal diagnostic system (e.g. DSM-IV, as well as research and clinical practice based on it). The use of agonist treatment in dual diagnosis heroin addicts has allowed us to gather valuable knowledge about the intrinsic, and historically and clinically documented mood-regulating effects of opiates. From the therapeutic point of view, the challenge of double diagnosis requires double competence from clinicians. The combination of opiate agonists and mood stabilizers often produces results difficult to obtain with the use of the two types of drugs separately. We therefore submit that the present conceptualization of the link between bipolar spectrum and addictive disorders has not only heuristic and scientific values, but also an important message for the clinician.

Abstract
OBJECTIVE The study was designed to determine the validity of the Mood Disorder Questionnaire-Adolescent Version (MDQ-A) as a screening instrument for bipolar disorders (I, II, not otherwise specified, and cyclothymia) in an adolescent outpatient psychiatric population. METHOD 104 adolescents and their parents completed the MDQ-A. Three versions of the MDQ-A were compared: (1) self report of symptoms by adolescent, (2) attributional report-how the adolescent believed teachers or friends would report his/her symptoms, and (3) parent report of adolescent's symptoms. DSM-IV diagnosis was made based upon the clinician-administered Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL), a semistructured diagnostic interview. MDQ-A items were summed, yielding a score for each adolescent ranging from 0 to 13 on each of the 3 MDQ-A versions. Each possible scoring threshold, in combination with co-occurrence of symptoms and behaviors and with moderate to serious problems caused by symptoms, was crossed with the results of the K-SADS-PL diagnostic interview to assess sensitivity and specificity. The study was conducted from April 2002 to September 2003. RESULTS A score of 5 or more items on the parent version yielded a sensitivity of 0.72 and specificity of 0.81, which were superior to self and attributional versions. CONCLUSIONS The MDQ-A completed by parents about their adolescents' symptoms may be a useful screening instrument for bipolar disorders in an adolescent psychiatric outpatient population.

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.

Abstract
OBJECTIVES The Diagnostic and Statistical Manual of Mental Disorders guidelines provide only a partial solution to the nosology and treatment of bipolar disorder in that disorders with common symptoms and biological correlates may be categorized separately because of superficial differences related to behavior, life history, and temperament. The relationship is explored between extremely rapid switching forms of bipolar disorder, in which manic and depressive symptoms are either mixed or switch rapidly, and forms of borderline personality disorder in which affective lability is a prominent symptom. METHODS A MedLine search was conducted of articles that focused on rapid cycling in bipolar disorder, emphasizing recent publications (2001-2004). RESULTS Studies examined here suggest a number of points of phenomenological and biological overlap between the affective lability criterion of borderline personality disorder and the extremely rapid cycling bipolar disorders. We propose a model for the development of 'borderline' behaviors on the basis of unstable mood states that sheds light on how the psychological and somatic interventions may be aimed at 'breaking the cycle' of borderline personality disorder development. A review of pharmacologic studies suggests that anticonvulsants may have similar stabilizing effects in both borderline personality disorder and rapid cycling bipolar disorder. CONCLUSIONS The same mechanism may drive both the rapid mood switching in some forms of bipolar disorder and the affective instability of borderline personality disorder and may even be rooted in the same genetic etiology. While continued clinical investigation of the use of anticonvulsants in borderline personality disorder is needed, anticonvulsants may be useful in the treatment of this condition, combined with appropriate psychotherapy.

Impact of temperamental mood lability on depressive mixed state. Psychopathology 2006; 39:19-24. [PMID: 16282715 DOI: 10.1159/000089659] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2004] [Accepted: 04/05/2005] [Indexed: 11/19/2022]
Abstract
BACKGROUND Cyclothymic temperament (which includes mood lability) is common in bipolar II disorder (BP-II). Depressive mixed state (DMX), a major depressive episode (MDE) mixed with intra-episode hypomanic symptoms (3 or more, according to a recently validated definition), was found to be common in BP-II and not uncommon in major depressive disorder (MDD). The study aim was to find the impact of temperamental mood lability (TML) on DMX. METHODS Consecutive 148 BP-II and 117 MDD outpatients presenting for MDE treatment were interviewed by the Structured Clinical Interview for DSM-IV as modified by Benazzi and Akiskal to reduce the false negative BP-II. Intra-MDE hypomanic symptoms were systematically assessed. Kraepelin, Angst, and Akiskal's definitions of temperamental mood lability (i.e., frequent up and down fluctuations of mood between major mood episodes since young age) were followed. RESULTS DMX was present in 61.5%, TML in 52.8%. In the DMX sample, TML was present in 57.6%, and in the non-DMX sample TML was present in 45.0% (OR = 1.6, 95% CI = 1.0-2.7). In the DMX sample, independent predictors of DMX with TML were BP-II and young age at onset. Intra-MDE hypomanic symptoms, and MDE, melancholic and atypical symptoms were not significantly different between DMX patients with TML and DMX patients without TML, apart from more temperamental interpersonal sensitivity in DMX patients with TML (OR = 2.0, 95% CI = 1.0-3.8). DISCUSSION DMX patients with TML had a younger onset age, suggesting that TML may facilitate the onset of DMX or that it may be a precursor of DMX. The association of BP-II with DMX, TML, and interpersonal sensitivity can make the course of BP-II more unstable and its treatment more complex.

Abstract
The study examines the psychometric properties of the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A) based on 717 (438 females and 279 males) healthy subjects in a Hungarian normative sample. The questionnaire is a self-report 110-item tool that postulates five affective temperaments: depressive, cyclothymic, irritable, hyperthymic, and anxious. Most of the TEMPS-A scales have excellent internal consistencies (0.78-0.84), except for the Depressive Temperament Scale, which had a Cronbach's alfa coefficient of 0.63. The item-analyses have identified a few deficient items which do not fit into the scale. In line with the literary data, women had higher mean scores on the depressive, cyclothymic, and anxious subscales, whereas men scored higher on the cyclothymic subscale. Cut-offs for each temperament were based on z-scores higher than + 2S.D. Dominant nervous-anxious (4.3%), depressive (3.8%), cyclothymic (3.2%), and irritable (3.2%) temperaments were the most common in this normative population, whereas dominant hyperthymic (1.8%) temperament was relatively uncommon. Factor analyses of the TEMPS-A items yielded considerable overlap between depressive and cognitive anxiety traits. The strongest correlation was observed between the anxious and the depressive temperament subscales in line with some international findings (r=0.62**). To test construct validity, we administered the Beck Depression Inventory, Profile of Mood States (shortened version) and the Cloninger Temperaments and Character Inventory, which all supported the validity of TEMPS-A subscales. Based on the results obtained with the Hungarian normative sample, the TEMPS-A is a reliable and valid instrument in personality psychology, and further refinement on clinical samples opens new and interesting research avenues.

Abstract
Bipolar disorders are a neglected subject in legal scholarship. Yet they affect decision-making across the spectrum of the law. This editorial analyses the approaches adopted across a variety of areas of legal decisions. It observes a lack of coherence in the approach of the law and attempts to identify a number of issues that are posed by the diverse symptoms of the bipolar disorders. It argues in favour of greater judicial and tribunal member education about the disorders.

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
Bipolar disorders usually present as alternating episodes of melancholy and mania. However, other clinical situations appear in a masked form before being spotted. The principal one is hypomania that declares itself as an attenuated form of a manic episode. Its principal signs are an increase in energy, hyperactivity and disinhibition. In other cases, bipolar disorders express themselves as impulsive behaviours. More rarely, the mask of a bipolar illness is translated into behaviours such as intermittent alcohol abuse. The consummation of alcohol is sudden and paroxysmal. It is a type of dipsomania. Finally, bipolar disorders can express themselves as difficulty in impulse control. The two most frequent examples are impulse buying and pathological gambling.

A comparison of recovered bipolar patients, healthy relatives of bipolar probands, and normal controls using the short TEMPS-A. J Affect Disord 2005; 85:147-51.

Abstract
OBJECTIVE To investigate the presence of temperament dysregulation in healthy relatives of bipolar probands (RBP), a population at high risk for developing mood disorders, by comparing them with clinically recovered bipolar patients (BP) and normal controls (NC). METHOD 52 RBP and 23 BP were originally recruited for a multicenter genetic study in bipolar disorders. NC (n=102) were also recruited by newspaper advertisement, radio and television announcements, flyers, newsletters, or word of mouth. All volunteers were asked to complete the TEMPS-A Scale, a self-report questionnaire designed to measure temperamental variations in psychiatric patients and healthy volunteers. In scoring temperaments, we relied upon the short validated version of the TEMPS-A [J. Affect. Disord. (2004)], from which traits with loadings <0.035 had been deleted. RESULTS To examine differences in temperament dimensions among the three groups, a MANCOVA model was constructed using diagnostic group as the fixed factor (BP vs. RBP vs. NC); effects of age and gender were adjusted as covariates. MANCOVA showed overall group effect on the dependent variables (Hotelling's F5,175=6.64, p<0.001). Four dependent variables (dysthymic, cyclothymic, irritable, and anxious temperaments) showed significant between-group differences. RBP showed lower cyclothymic temperament scores than BP, but higher scores than NC. BP and RBP showed higher anxious temperament scores than NC. Hyperthymic scores were significantly highest in the NC. LIMITATION In view of the small cell sizes, bipolar I vs. bipolar II subanalyses could not be conducted. CONCLUSIONS Methodologic strengths of the present analyses is that the BP group had clinically recovered, and we used the validated short version of the TEMPS-A for the present analyses. Our findings suggest that some clinically healthy relatives of bipolar probands exhibit a subclinical cyclothymic instability in mood, interest, self-confidence, sleep, and/or energy as well as anxiety proneness that is not observed among normal controls. These traits may represent vulnerability markers and could presumably be used to identify individuals at high risk for developing bipolar spectrum disorders, or specific clinical subtypes (e.g., bipolar I, bipolar II) within this spectrum. This is a conceptual perspective with many unanswered questions. Resolution of these questions will require innovative definitions of phenotypes to be included in the analyses of the temperament subscales in different populations. The temperament subscales themselves need to be calibrated properly, to find out which traits or specific combinations of trains are most promising. More extensive and complex quantitative trait analyses of these temperaments in a much expanded sample are reported elsewhere in this issue [J. Affect. Disord. (2004)].

Validating affective temperaments in their subaffective and socially positive attributes: psychometric, clinical and familial data from a French national study. J Affect Disord 2005; 85:29-36.

Abstract
BACKGROUND One of the major objectives of the French National EPIDEP Study was to show the feasibility of systematic assessment of bipolar II (BP-II) disorder and beyond. In this report we focus on the utility of the affective temperament scales (ATS) in delineating this spectrum in its clinical as well as socially desirable expressions. METHODS Forty-two psychiatrists working in 15 sites in four regions of France made semi-structured diagnoses based on DSM IV criteria in a sample of 452 consecutive major depressive episode (MDE) patients (from which bipolar I had been removed). At least 1 month after entry into the study (when the acute depressive phase had abated), they assessed affective temperaments by using a French version of the precursor of the Temperament Evaluation of Memphis, Pisa, Paris and San Diego (TEMPS). Principal component analyses (PCA) were conducted on hyperthymic (HYP-T), depressive (DEP-T) and cyclothymic (CYC-T) temperament subscales as assessed by clinicians, and on a self-rated cyclothymic temperament (CYC-TSR). Scores on each of the temperament subscales were compared in unipolar (UP) major depressive disorder versus BP-II patients, and in the entire sample subdivided on the basis of family history of bipolarity. RESULTS PCAs showed the presence of a global major factor for each clinician-rated subscale with respective eigenvalues of the correlation matrices as follows: 7.1 for HYP-T, 6.0 for DEP-T, and 4.7 for CYC-T. Likewise, on the self-rated CYC-TSR, the PCA revealed one global factor (with an eigenvalue of 6.6). Each of these factors represented a melange of both affect-laden and adaptive traits. The scores obtained on clinician and self-ratings of CYC-T were highly correlated (r=0.71). The scores of HYP-T and CYC-T were significantly higher in the BP-II group, and DEP-T in the UP group (P<0.001). Finally, CYC-T scores were significantly higher in patients with a family history of bipolarity. CONCLUSION These data uphold the validity of the affective temperaments under investigation in terms of face, construct, clinical and family history validity. Despite uniformity of depressive severity at entry into the EPIDEP study, significant differences on ATS assessment were observed between UP and BP-II patients in this large national cohort. Self-rating of cyclothymia proved reliable. Adding the affective temperaments-in particular, the cyclothymic-to conventional assessment methods of depression, a more enriched portrait of mood disorders emerges. More provocatively, our data reveal socially positive traits in clinically recovering patients with mood disorders.

The relationship of Kraepelian affective temperaments (as measured by TEMPS-I) to the tridimensional personality questionnaire (TPQ). J Affect Disord 2005; 85:17-27.

Abstract
BACKGROUND There is considerable uncertainty in the current literature about the relationship between personality dimensions and affective temperaments. METHOD We compared-in a non-ill 14-26-year-old Italian student population of 1010-the affective temperaments of classic psychiatry conceived as subaffective traits [and measured through the Temperament Assessment of Memphis, Pisa, Paris and San Diego-Interview Version (TEMPS-I) in the Akiskal and Mallya Operationalization] with Cloninger's revised Tridimensional Personality Questionnaire (TPQ) deriving from the experimental psychology tradition. RESULTS The Depressive Temperament (DT) and Harm Avoidance (HA), loaded positively on the same canonical variate, whereas the hyperthymic (HT) strongly, and Novelty Seeking (NS) moderately, loaded negatively. In contrast, the Cyclothymic Temperament (CT) loaded highly positively on a second variate, on which both Novelty Seeking strongly and Harm Avoidance moderately loaded positively. Reward Dependence (RD), Persistence (P), and Irritable Temperament (IT) did not significantly relate to any temperamental and personality constructs. At a subdimensional level of TPQ 'shyness with strangers', 'stoic rigidity', 'detachment', 'fear of uncertainty', 'reflection', and 'anticipatory worry' correlated best with the DT. 'Gregariousness', 'exploratory excitability', 'uninhibited optimism', 'attachment', 'confidence', 'extravagance', 'independence', 'vigor', and 'impulsiveness' correlated best with HT. Lastly, 'anticipatory worry', 'disorderliness', 'sentimentality', and 'fatigability' correlated best with CT. CONCLUSIONS The data provide concurrent validity to TEMPS-I and, as earlier suggested by Cloninger, indicate that (as expected) high HA and DT are related. High NS is both related to the HT and CT, and (somewhat unexpectedly), the CT is related to high HA. In a more theoretical vein, hyperthymic-novelty seeker can be predicted to be overrepresented among those with high achievement; on the other hand, a moody, restless disposition (a cyclothymic-harm avoidant type) may engage in outrageous behavior and be liable to negative affective arousal. We submit that these considerations could shed some light on the origin of socially adaptive behavior ('sunny' or sanguine types) on the one hand, and borderline conditions, anxious-hostile bipolarity ('dark' types) on the other.

Cyclothymic temperament as a prospective predictor of bipolarity and suicidality in children and adolescents with major depressive disorder. J Affect Disord 2005; 85:181-9.

Abstract
INTRODUCTION Although several recent studies suggest that bipolar disorder most commonly begins during childhood or adolescence, the illness still remains under-recognized and under-diagnosed in this age group. As part of the French Bipolar network and in line with the hypothesis that juvenile depression is pre-bipolar , we evaluated the rate of onset of bipolar disorders in a naturalistic 2-year prospective study of consecutive, clinically depressed children and adolescents, and to test whether the cyclothymic temperament underlies such onset. METHODS Complete information was obtained from both parents and patients in 80 of 109 depressed children and adolescents assessed with Kiddie-SADS semi-structured interview, according to DSM IV criteria. They were also assessed with a new questionnaire on cyclothymic-hypersensitive temperament (CHT) from the TEMPS-A cyclothymic scale adapted for children (provided in ), and other assessment tools including the Child Depression Inventory (CDI), Young Mania Rating Scale, Clinical Global Assessment Scale (CGAS), and Overt Aggressive Scale (OAS). RESULTS Of the 80 subjects, 35 (43%) could be diagnosed as bipolar at the end of the prospective follow-up. This outcome was significantly more common in those with cyclothymic temperament measured at baseline. Most of these patients were suffering from a special form of bipolar disorder, characterized by rapid mood shifts with associated conduct disorders (CD), aggressiveness, psychotic symptoms and suicidality. LIMITATION The primary investigator, who took care of the patients clinically, was not blind to the clinical and psychometric data collected. Since all information was collected in a systematic fashion, the likelihood of biasing the results was minimal. CONCLUSION We submit that the CHT in depressed children and adolescents heralds bipolar transformation. Unlike hypomanic or manic symptoms, which are often difficult to establish in young patients examined in cross-section or by history, cyclothymic traits are detectable in childhood. Our data underscore the need for greater effort to standardize the diagnosis and treatment of pre-bipolar depressions in juvenile patients.

The cyclothymic temperament in healthy controls and familially at risk individuals for mood disorder: endophenotype for genetic studies? J Affect Disord 2005; 85:135-45.

Abstract
BACKGROUND The modern concept of affective disorders focuses increasingly on the study of subthreshold conditions on the border of manic or depressive episodes. Indeed, a spectrum of affective conditions spanning from temperament to clinical episodes has been proposed by the senior author. As bipolar disorder is a familial illness, an examination of cyclothymic temperament (CT) in controls and relatives of bipolar patients is of major relevance. METHODS We recruited a total sample of 177 healthy symptom-free volunteers. These controls were divided into three groups. The first one is comprised of 100 normal subjects with a negative familial affective history (NFH); the second of 37 individuals, with positive affective family history (PFH); and a third of 40 subjects, with at least one sib or first-degree kin with bipolar disorder type I according to the DSM-IV (BPR). The last two groups defined at risk individuals. We interviewed all subjects with CT, as described by the senior author. RESULTS We found a statistically significant difference in the rates of CT between the subjects in BPR versus others. CT was also more prevalent in the PFH compared with NFH. Additionally, the simple numeration of the CT traits exhibited gradation in the distribution of individuals inside the NFH, PFH and BPR. Finally, categorically defined CT and CT traits predominated in females. LIMITATION and CONCLUSION Although not all relatives of bipolar probands were studied, our results exhibit an aggregation of CT in families with affective disorder-and more specifically those with bipolar background. These results allow us to propose the importance of including CT for phenotypic characterization of bipolar disorder. Furthermore, our results support a spectrum concept of bipolar disorder, whereby CT is distributed in ascending order in the well-relatives of those with depressive and bipolar disorders. We submit that this temperament represents a behavioral endophenotype, serving as a link between molecular and behavioral genetics.

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.

Abstract
BACKGROUND This study aims to demonstrate the relevance of temperament to job stress. METHOD The subjects were 848 male and 366 female Japanese company employees. Temperament Evaluation of Memphis, Pisa, Paris and San Diego-Autoquestionnaire version (TEMPS-A) and Munich Personality Test (MPT) were administered to assess temperaments, and the NIOSH Generic Job Stress Questionnaire (GJSQ) to assess job stress. We used hierarchical multiple linear regression analysis in order to demonstrate whether temperament variables added any unique variance after controlling the effects of other predictors such as gender, age and job rank. RESULTS In all subscales of the GJSQ, temperament predicted a large share of the variance in job stress. Remarkably, for interpersonal relationship stressors, the temperament variables added greater variance than that predicted by gender, age and job rank. Summary of the hierarchical linear regression analysis showed that the irritable temperament was associated with the most prominent vulnerability, followed by cyclothymic and anxious temperaments. The schizoid temperament had difficulty in the area of social support. On the other hand, the hyperthymic temperament displayed significant robustness in facing most job stressors; the melancholic type showed a similar pattern to a lesser degree. LIMITATION The findings may be different in a clinical Japanese sample, or a cohort of healthy employees from a different cultural background. CONCLUSIONS Temperament influences job stress significantly-indeed, it impacts on such stress with greater magnitude than age, gender and job rank in most areas examined. Temperament influences interpersonal relationship stressors more than workload-related stressors. Interestingly, in line with previous clinical and theoretical formulations, the hyperthymic and melancholic types actually appear to be "hyper-adapted" to the workplace.

Affective temperaments as measured by TEMPS-A in patients with bipolar I disorder and their first-degree relatives: a controlled study. J Affect Disord 2005; 85:127-33.

Abstract
BACKGROUND The aims of this study were to identify the dominant affective temperamental characteristics of patients with bipolar disorder (BP) and their clinically well first-degree relatives and to compare the prevalence rates of these temperaments with those in healthy control subjects. METHODS One hundred bipolar I probands and their 219 unaffected first-degree relatives were enrolled in the study. The control group consisted of healthy subjects without any personal or family history of bipolar disorder, matched with the age and gender of the probands and first-degree relatives. To identify the dominant affective temperaments, the Turkish version of TEMPS-A scale was used. RESULTS At least one dominant temperament was found in 26% of the proband group, in 21.9% of the relative group, and 6.0% and 10.0% of the control groups, respectively. The most noteworthy finding was that both the probands and their relatives had significantly higher frequency of hyperthymic temperament than the controls. LIMITATIONS Temperament had not been assessed premorbidly in the probands with bipolar disorder. CONCLUSIONS The study supports the familial, possibly genetic, basis for the hyperthymic temperament in the genesis of bipolar I dosorder. That the cyclothymic temperament was not similarly represented, may be due to the higher specificity of the cyclothymic temperament to the bipolar II sybtype (which we did not study). More research is needed on the relevance of cyclothymic and other temperaments to the genetics of bipolar disorders selected by rigorous subtyping along the clinical spectrum of bipolarity.

Abstract
BACKGROUND With the possible exception of cyclothymia in artists, there is a paucity of data in the literature on the temperament in different professions. METHODS For this exploratory study, we sought to generate preliminary data on temperaments among psychiatric outpatients, including physicians (n=41), lawyers (n=30), managers and executives (n=35), industrialists (n=48), architects (n=27), journalists (n=34), and a mixed group of artists (n=48). They were compared with age, sex, social class, and affective disorder matched outpatients outside of these professions, drawn from the same clinical settings to serve as our Comparison Group (CG, n=120). We used an interview version of the Akiskal-Mallya criteria for temperaments. We finally used the DSM-III-R obsessive compulsive personality (OC traits). RESULTS Compared with the CG, lawyers and physicians had high rates of dysthymic temperament and OC traits. Managers, like lawyers and doctors, had high rates on OC traits but were different in being very low on cyclothymic and twice as hyperthymic than the CG was. Industrialists, who, by definition, were self-made, had even higher rates of hyperthymic traits. Both architects and artists seemed to have benefited from being cyclothymic (3-4 times higher than CG's); interestingly, architects had higher levels of OC traits, and artists were less obsessional than the CG was. Overall, among managers/executives and lawyers, 41% met criteria for affective temperaments, whereas the equivalent rate among the remainder was 77%. LIMITATION Given that this is a chart review of existing clinical records, it was not possible to be blind to the profession of the patients. A mixed group of artists may have obscured differences among artists from different domains of art (e.g., poets vs. performing artists), and the same can be said of physicians (e.g., internists vs. surgeons). A disclaimer would be appropriate: Ours is not a study on eminence in the different professions but on the temperament and personality profiles that distinguish among them. CONCLUSIONS Despite the foregoing limitations and overlapping attributes in the different professions, they nonetheless emerged as having distinct temperamental and personality profiles. Dysthymic and obsessional attributes are notable in lawyers and physicians. We confirm the role of cyclothymia in artists and architects. The role of the hyperthymic temperament in managers, self-made industrialists, and journalists, to the best of our knowledge, is being reported for the first time. The role of cyclothymic and hyperthymic temperaments appears to be moderated by obsessional traits across the entire professional realm examined. In particular, artists' creative imagination appears "liberated" by low levels of OC traits, whereas among architects, relatively high levels of OC traits seem to contribute to the execution of their work. More tentatively, judging from the overall levels of affective temperaments in the remaining professions, on average, more of the managers/executives than self-made industrialists could be described as "colder" in temperament, and more of the physicians "warmer" than lawyers are. Journalists, as a group, appeared to possess the broadest representation of affective temperaments. The foregoing conclusions must be regarded as tentative, even hypothetical, in need of verification among professionals without major psychiatric disorders. Nonetheless, temperament profiles among psychiatrically ill professionals in the seven professional realms studies can help predict how they relate to their doctors, family members, colleagues, coworkers, and clients/patients. Such knowledge, in turn, can help the therapeutic process.
