Abstract
The transition to parenthood is often accompanied by depression and stress. Several studies have established risk factors for postpartum depression, e.g., antenatal depression. However, only a few studies have involved fathers. Moreover, most studies focus on the prevalence of depression instead of intraindividual changes over time. Our study investigated differential effects of parental psychopathology and child difficulty on the course of depressive symptoms and feelings of stress for first-time mothers and fathers. Seventy-four mothers and 58 fathers completed questionnaires on depressive symptoms (EPDS) and feelings of stress during pregnancy, and at 1, 3, 12, and 18 months postpartum. Parents rated children's difficulty-fussiness at 3, 12, and 18 months postpartum (ICQ). Parental psychopathology was established during pregnancy using self-reports (SCL-90-R) and anamnestic data. In mentally healthy mothers and fathers depressive symptoms decreased from pregnancy to 18 months postpartum, whereas parents with psychopathology in pregnancy showed a tendency to prolonged depressive phases. In parents with psychopathology, feelings of stress peaked at 12 months postpartum. Child difficulty was associated with elevated levels of psychosocial stress, but only for some participants. Parental psychopathological symptoms during pregnancy should thus be considered as a risk factor for elevated and prolonged depression and elevated psychosocial stress in mothers and fathers across the transition to parenthood.

Abstract
OBJECTIVE This study was designed to investigate the link among attention deficit hyperactivity disorder (ADHD) in adults, novelty-seeking temperament, and the 48-base pair (bp) dopamine D4 receptor (DRD4) gene variant. METHOD This study drew from a larger molecular genetic study of ADHD in which the ascertainment criterion was having an affected sibling pair with ADHD. Parents (N=171) from 96 families provided data. Of the 171 parents, 56 (33%) had a lifetime history of ADHD, with 28 (50%) continuing to meet DSM-IV criteria (i.e., "persistent" ADHD). Latent variable modeling was used to test whether the DRD4 gene variant or Temperament and Character Inventory factors could predict ADHD. RESULTS Using latent variable modeling, the authors were able to confirm the first-order factor structure of the Temperament and Character Inventory. Furthermore, novelty seeking predicted ADHD lifetime diagnosis (R(2)=26%), while the DRD4 gene variant independently predicted ADHD (R(2)=5%) but not novelty seeking. CONCLUSIONS In this unique sample of parents from multiply affected ADHD families, novelty seeking and the 48-bp DRD4 variant were associated with a lifetime history of ADHD. However, the association between novelty seeking and ADHD does not appear to be due to variation in the 48-bp DRD4 variant.

Abstract
OBJECTIVE The identification of specific temperament dimensions as correlates or risk factors for psychopathology in infancy, childhood and adolescence might provide key information to elucidate causal mechanisms that underlie these relationships. METHODS A non-clinical sample of 1010 students (518 males and 492 females) without major psychiatric disorders was given psychometric assessment using TEMPS-I (the Italian Semi-structured Interview version of the Temperament Evaluation of Memphis, Pisa, and San Diego) and EBC (Emotional and Behavioral Checklist in Infancy, Childhood and Adolescence). Grouping the subjects on the basis of the highest z-score obtained on each of the four temperament scales of TEMPS-I, it was possible to identify the dominant affective temperamental (AT) inclination of each individual: 283 (28.0%) subjects were classified as dominant depressive temperament, 446 (44.2%) as dominant hyperthymic, 221 (21.9%) as dominant cyclothymic, and 60 (5.9%) as dominant irritable. The effects of AT dominant groups on EBC scores were tested by one-way analysis of variance. To control for age and sex effects, we tested the differences within dominant AT groups by a multiple classification analysis (MCA). RESULTS As expected, subjects with depressive temperament traits were characterized by social inhibition and lack of antisocial and hyperactive behavior. Cyclothymic subjects reported the highest number of emotional and behavioral problems, compared with the other dominant ATs (depressive, hyperthymic and irritable). In particular, a cyclothymic disposition was most frequently associated with anxiety-sleep disturbances, sensitivity to separation, eating disturbances in females and antisocial-aggressive behavior in males. The relationship between cyclothymic temperament and anxiety-sleep disturbances and antisocial-aggressive behavior increased with age. LIMITATIONS Cross-sectional study based on retrospective evaluation. CONCLUSIONS Within a juvenile population, depressive temperament is a construct partially overlapping with behavioral inhibition, while extremes of emotionality and behaviors occur preponderantly in those with cyclothymic traits. The cyclothymic disposition turned out to be the most 'morbid', and associated with both internalizing and externalizing disturbances.

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.

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.

Abstract
BACKGROUND Certain sexual behaviors and abuse of substances contribute to the risk of becoming HIV-infected. Because dispositional characteristics are likely to influence this process, we examined the association between temperament and HIV serostatus in subjects with heavy use of drugs and various sexual risk behaviors. METHODS Two hundred and thirty individuals (81% of whom were HIV-infected) were assessed for underlying temperamental characteristics, substance use, and risky sexual behaviors. Toward this goal, a factor analysis was conducted on a new self-rated Temperament Autoquestionnaire (Temperament Evaluation of Memphis, Pisa, Paris and San Diego-Autoquestionnaire (TEMPS-A)). MANOVA was used to examine overall associations between risky behaviors and temperament. Additionally, directed MANOVAs were conducted for each of six drugs of abuse (alcohol, marijuana, cocaine, opioids, other stimulants, and sedative hypnotics). RESULTS Factor analysis confirmed the hypothesized temperament structure of five distinct factors: Cyclothymic, hyperthymic, anxious, irritable-explosive, and depressive. Heavy users of cocaine, other stimulants, and alcohol were more likely to have an irritable-explosive temperament. Interestingly, heavy users of opioids were more likely to show depressive and hyperthymic traits. The inclusion of HIV status as a predictor of temperament did not alter the results. Unlike a previous study, no direct significant relationships were found between risky sexual behaviors and specific temperaments. LIMITATIONS Relatively small sample size for a factor analytic study, and cross-sectional design, which cannot determine a cause and effect relationship. CONCLUSIONS We succeeded in studying and validating five distinct affective temperaments in a substance abuse population. Irritable-explosive, and to a lesser extent, depressive and hyperthymic traits, were associated with substance use, and may place individuals at risk for HIV infection via that mechanism. That current risky sexual practices were not directly linked to temperament may reflect modification in sexual behavior following the acquisition of HIV disease.

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.

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.

Abstract
BACKGROUND Stimulant abuse and dependence in confusing admixtures with features of bipolar disorder has been variously conceptualized. DSM-IV-TR rules tend to be liberal in permitting the diagnosis of substance-induced disorder, and rather strict for a bipolar diagnosis in such cases. Accordingly, if bipolarity is ever considered in this interface, it usually pertains to syndromal bipolar I disorder. METHOD We therefore focused on the more prevalent but relatively neglected admixture of stimulant abuse with bipolar II and lesser degrees of bipolarity. We examined in our dual diagnosis program the longitudinal progression of the dual pathology in 10 patients who had proven refractory to past efforts to treat the stimulant component. In doing so, we wished to better delineate the nature of the clinical interface of the stimulant bipolar spectrum and its response to anticonvulsant mood stabilizers. RESULTS In nearly all cases cyclothymic and hyperthymic traits preceded the use of stimulants by years, which seemed to serve the purpose of controlling or maintaining the subthreshold rewarding mood condition. Eventually clinically more ominous and socially destructive pathology evolved, with contributions from both the bipolar diathesis and the addictive process. Seven of 10 cases had bipolar familial indicators. Nearly all evidenced hypomanic and/or irritable depressive states with mixed features during protracted sobriety from the stimulant. Except for two of the 10 patients, substantial (30-45 point) gains were made on DSM-IV-TR axis V general assessment of functioning (GAF) scores with the use of largely "mood-stabilizing" anticonvulsants. This was paralleled with the reduction of craving. These data highlight the human dimensions of the bipolar-stimulant abuse interface, and document functional outcomes (rather than mere changes in rating scales which may not necessarily reflect clinically relevant improvement). LIMITATION Open case series of 10 patients. CONCLUSION We propose a bipolar-stimulant spectrum-what the senior author has elsewhere labeled bipolar III-1/2-where subthreshold bipolar traits are complicated by stimulant abuse, eventually leading to pathology characteristic of both disorders. The contribution of bipolarity to this spectrum is supported by: (1) premorbid cyclothymic and hyperthymic traits; (2) familial bipolarity; (3) presence of subthreshold bipolar signs and symptoms during protracted sobriety. We further submit that anticonvulsants in this spectrum not only treat the acute escalation of activated and mixed depressive states, withdrawal phenomena, and craving for the stimulant, but also the craving for activation and mood enhancement of the underlying temperament. We submit that the latter might be crucial for the successful attenuation of the underlying diathesis for stimulant seeking behavior, abuse and dependence.

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 The purpose of the study was to evaluate the psychometric properties of the German version of the TEMPS-A questionnaire. Besides the reliability of the temperament scales, validity was the focus of interest. Therefore, the relationship between the TEMPS-A and the well-established personality questionnaire NEO-FFI, whose factors show theoretical overlap with temperaments, was investigated. METHOD A total of 227 students aged between 20 and 42 years were asked to fill in both instruments. Reliability coefficients for the five temperament scales and correlations among the scales of both questionnaires were calculated, as well as multiple linear regression analysis with the five personality factors and gender as independent, and the five temperaments as dependent variables. RESULTS Reliability indices for the five temperament scales were satisfactory, with values ranging between 0.63 (depressive) and 0.76 (anxious). Women scored higher on depressive and anxious scales, whereas men had higher scores on hyperthymic temperament. Correlations within the temperament scales showed close relationships between depressive, anxious and cyclothymic temperaments; cyclothymic and irritable temperament were also related. The personality factors of the NEO-FFI predicted temperaments fairly well and explained between 41% and 58% of the variance; the main effects were exerted by neuroticism and extraversion, while the irritable temperament was primarily explained by low agreeableness. LIMITATION The study sample was relatively small and selected. CONCLUSION The TEMPS-A scale has sufficient reliability and good validity in a non-clinical sample. It opens new possibilities for clinical research at the interface of mental disorders, temperament and personality. Such research is in progress.

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 The array of different diagnoses and clinical presentations seen in the family members of bipolar probands suggests a quantitative or spectrum phenotype. Consistent with this idea, it has been proposed that an underlying quantitative variation in temperament may be the primary phenotype that is genetically transmitted and that it in turn predisposes to bipolar disorder (BP). Choosing the appropriate phenotypic model for BP is crucial for success in genetic mapping studies. To test this theory, various measures of temperament were examined in the family members of bipolar probands. We predicted that a gradient of scores would be observed from those with BP to those with major depression to unaffected relatives to controls. METHODS Members of 85 bipolar families and 63 control subjects were administered clinical interviews for diagnosis (SCID) and two temperament assessments, the TEMPS-A and TCI-125. Subjects with BP, major depressive disorder, unaffected relatives, and controls were compared on each temperament scale and on eight factors extracted from a joint factor analysis of the TEMPS-A and TCI-125. RESULTS The four groups were found to be significantly different and with the expected order of average group scores for four of the TEMPS-A scales, three of the TCI-125 scales, and one of the extracted factors. On the fifth TEMPS-A scale, hyperthymic, controls scored higher than the other three subject groups contrary to expectations. Significant differences were seen between unaffected relatives and controls on the hyperthymic scale and on the first extracted factor, anxious/reactive. LIMITATIONS Controls were mainly recruited through advertisements, which may have introduced an ascertainment bias. It is also possible that mood state at the time of completing the questionnaire influenced subject's rating of their temperament. Additionally, bipolar I and bipolar II subjects were placed in the same group even though they had some differing clinical features. CONCLUSIONS Our data support the theory that some dimensions of temperament are transmitted in families as quantitative traits that are part of a broader bipolar spectrum. In particular, the hyperthymic scale of the TEMPS-A and the anxious/reactive extracted factor distinguished unaffected relatives from controls. The hyperthymic scale yielded results opposite to expectation with controls higher than any family group. This may be an artifact of the self-rated form of the questionnaire, a consequence of our grouping bipolar I and II subjects together, or the result of a "protective" factor and bears further study. Nevertheless, both of these scales may be useful quantitative traits for genetic mapping studies.

Abstract
OBJECTIVE Understanding of mood disorders can be enhanced through assessment of temperamental traits. We explored temperamental commonalities and differences among euthymic bipolar (BP) and unipolar (MDD) mood disorder patients, creative discipline graduate student controls (CC), and healthy controls (HC). METHODS Forty-nine BP, 25 MDD, 32 CC, and 47 HC completed self-report temperament/personality measures including: The Affective Temperament Evaluation of Memphis, Pisa, Paris and San Diego (TEMPS-A); the Revised NEO Personality Inventory (NEO-PI-R); and the Temperament and Character Inventory (TCI). RESULTS Euthymic BP, MDD, and CC, compared to HC, had significantly increased cyclothymia, dysthymia and irritability scores on TEMPS-A; increased neuroticism and decreased conscientiousness on NEO-PI-R; and increased harm avoidance and novelty seeking as well as decreased self-directedness on TCI. TEMPS-A cyclothymia scores were significantly higher in BP than in MDD. NEO-PI-R openness was increased in BP and CC, compared to HC, and in CC compared to MDD. TCI self-transcendence scores in BP were significantly higher than in MDD, CC, and HC. LIMITATIONS Most of the subjects were not professional artists, and represented many fields; temperament might be different in different art fields. CONCLUSIONS Euthymic BP, MDD, and CC compared to HC, had prominent temperamental commonalities. However, BP and CC had the additional commonality of increased openness compared to HC. BP had particularly high Cyclothymia scores that were significantly higher then those of MDD. The prominent BP-CC overlap suggests underlying neurobiological commonalities between people with mood disorders and individuals involved in creative disciplines, consistent with the notion of a temperamental contribution to enhanced creativity in individuals with bipolar disorders.

Abstract
BACKGROUND Although generalized anxiety disorder (GAD) is currently described as a time-limited state mental disorder, emerging evidence suggests that it is best considered as an exaggeration of a putative "anxious temperament" (AT). It is presently unknown whether it is a distinct or unitary construct of a melange of anxious traits related to Cluster-C personality disorders. METHODS As part of a Franco-American collaborative study, we developed the 15-item Operational Criteria for Anxious Personality (OCAP), expanding criteria sets developed earlier by one of us (H.S.A.). The study, which was conducted in the French primary care medical sector, included 1112 young adults (18-40 years), seeking help for isolated anxious complaints, never treated before-and without any diagnosable disorder on the axis I of DSM-IV. As previous papers have reported the preliminary validity of OCAP, especially concurrent validity with the State-Trait Anxiety Inventory (STAI) (Speilberger), in this report, we focus on its full psychometric properties. RESULTS The present data indicate a normal distribution of AT items, a satisfactory Chronbach's coefficient (0.64), and the presence at intake of three different subtypes of AT: "anxious-avoidant," "anxious-phobic," and "anxious-sensitive." After a prospective 6-month follow-up, the major criteria of AT were stable in 80% of cases, and for specific AT items, the stability rate varied between 65% and 80%; much of the unstable items were accounted by improvement during naturalistic treatment. The latter could explain the different factor structure obtained at follow-up, which tended to be less heterogeneous, and represented by one global factor. LIMITATION We used a categorical (yes/no) rather than a Likert-type gradation of frequency and intensity of anxiousness items and relatively low number of items, especially for those involving worrying about one's own health or that of one's loved ones. CONCLUSIONS Anxiousness as a temperamental dimension appears to involve putative subtypes along "worrying," "phobic," "sensitive" (and "avoidant") dimensions.

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.

Abstract
OBJECTIVE To validate a short English-language version of the Temperament Evaluation of Memphis, Pisa, Paris and San Diego-autoquestionnaire version (TEMPS-A), a self-report questionnaire designed to measure temperamental variations in psychiatric patients and healthy volunteers. Its constituent subscales and items were formulated on the basis of the diagnostic criteria for affective temperaments (cyclothymic, dysthymic, irritable, hyperthymic, and anxious), originally developed by the first author and his former collaborators. Further item wording and selection were achieved at a later stage through an iterative process that incorporated feedback from clinicians, researchers, and research volunteers. METHOD A total of 510 volunteers (284 patients with mood disorders, 131 relatives of bipolar probands, and 95 normal controls) were recruited by advertisement in the newspapers, announcements on radio and television, flyers and newsletters, and word of mouth. All participants were interviewed using the Structured Clinical Interview for DSM-III-R, and completed the 110-item TEMPS-A and the Temperament and Character Inventory (TCI-125). The factorial structure, the alpha coefficients, and the item-total correlations coefficients of the TEMPS-A and the correlation coefficients between the dimensions of the TCI and the TEMPS-A subscales were then determined. RESULTS A principal components analysis with a Varimax rotation found that 39 out of the 110 original items of the TEMPS-A loaded on five factors that were interpreted as representing the cyclothymic, depressive, irritable, hyperthymic, and anxious factors. Coefficients alpha for internal consistency were 0.91 (cyclothymic), 0.81 (depressive), 0.77 (irritable), 0.76 (hyperthymic), and 0.67 (anxious) subscales. We found statistically significant positive correlations between all-but the hyperthymic-subscales and harm avoidance. Positive correlations with the hyperthymic and cyclothymic, and novelty seeking and negative correlations with the remaining subscales were also recorded. Other major findings included positive correlations between the hyperthymic and reward dependence, persistence and self-directedness; positive correlation between the self-transcendence and the cyclothymic, hyperthymic and the anxious; and negative correlations between the depressive, cyclothymic, irritable, anxious and cooperativeness. LIMITATION As the full-scale anxious temperament was added after the four scales of the TEMPS-A were developed, it has only been evaluated in 345 subjects. CONCLUSIONS These data indicate that the TEMPS-A in its shortened version is a psychometrically valid scale with good internal consistency. The proposed five subscale structure is upheld. Concurrent validity against the TCI is shown. Most importantly, for each of the temperaments, we were able to show positive attributes which are meaningful in an evolutionary context, along with traits which make a person vulnerable to mood shifts. This hypothesized dual nature of temperament, which is upheld by our data, is a desirable characteristic for a putative behavioral endophenotype in an oligogenic model of inheritance for bipolar disorder.

Abstract
Our aim was to examine the relationship between personality dimensions and hypochondriacal concerns and somatic symptoms in a military population. The Schedule of Nonadaptive and Adaptive Personality along with measures of hypochondriacal concerns and somatic symptoms were administered to 602 military veterans who had been on active duty during the 1991 Gulf War. Factor analyses identified six separable dimensions-two of hypochondriacal concerns, two of somatic symptoms, and two of possible mechanisms of symptom generation-for study. Multiple regression models determined the proportion of variation in these measures of somatic distress explained by personality scales. Personality measures explained between 26% and 38% of the variance in hypochondriacal concerns and somatic symptoms, and Negative Temperament accounted for most of this. Moderately strong positive correlations were observed between trait scales Mistrust, Low Self-Esteem, and Eccentric Perceptions and the various measures of somatic distress. Thus, when Negative Temperament was taken into account, few significant correlations between personality measures and hypochondriacal concerns or somatic symptoms remained. Negative temperament or neuroticism is strongly associated with hypochondriacal concerns. Important features of hypochondriasis and somatic distress appear to lie within the domain of personality. It remains for future research to show whether negative temperament is a vulnerability factor for hypochondriasis or hypochondriasis is itself a personality disorder.

Abstract
Currently, in the UK military, and particularly in the Army, a significant number of personnel are regularly discharged on the grounds of being assessed as "Temperamentally Unsuitable (TU) for military duties", under Queen's Regulations (QRs): (Army) 9.414 and 9.434 (1). In the last two years (2001--2003), preliminary figures suggest that approximately 700 serving personnel were recommended for discharge under this category by only four psychiatrists in the south of England. The regulations governing TU have been in existence and essentially unchanged since their development long before the 1960s albeit subject to parliamentary quinquennial review. The Army General and Administrative Instructions (AGAI) (2) standards also remain unchanged over this period. This paper raises questions about the current validity and relevance of existing TU concepts and regulations with suggestions as to what is being proposed in the context of changing roles, technology and advances in the modern armed forces.

Abstract
OBJECTIVE This study examined the extent to which individuals with a lifetime diagnosis of recurrent unipolar disorder endorse experiencing manic/hypomanic symptoms over their lifetimes and compared their reports with those of patients with bipolar I disorder. METHOD The study group included 117 patients with remitted recurrent unipolar depression and 106 with bipolar I. Subjects had their clinical diagnosis confirmed by the Mini International Neuropsychiatric Interview and were administered the Structured Clinical Interview for the Mood Spectrum, which assesses lifetime symptoms, traits, and lifestyles that characterize threshold and subthreshold mood episodes as well as "temperamental" features related to mood dysregulation. RESULTS The patients with recurrent unipolar depression endorsed experiencing a substantial number of manic/hypomanic symptoms over their lifetimes. In both patients with recurrent unipolar depression and patients with bipolar I disorder, the number of manic/hypomanic items endorsed was related to the number of depressive items endorsed. In the group with recurrent unipolar depression, the number of manic/hypomanic items was related to an increased likelihood of endorsing paranoid and delusional thoughts and suicidal ideation. In the bipolar I group, the number of lifetime manic/hypomanic items was related to suicidal ideation and just one indicator of psychosis. CONCLUSIONS The presence of a significant number of manic/hypomanic items in patients with recurrent unipolar depression seems to challenge the traditional unipolar-bipolar dichotomy and bridge the gap between these two categories of mood disorders. The authors argue that their mood spectrum approach is useful in making a more accurate diagnostic evaluation in patients with mood disorders.

Abstract
OBJECTIVE The authors examined the capacity of alexithymia to predict a broad range of psychiatric symptoms relative to that of other personality dimensions, age, and gender. METHOD The Toronto Alexithymia Scale, the Temperament and Character Inventory, and the SCL-90-R were administered to 254 psychiatric patients. Multivariate linear regression analyses were performed. RESULTS The difficulties identifying feelings factor of the Toronto Alexithymia Scale significantly predicted all SCL-90-R subscale scores and was particularly effective, relative to the personality dimensions of the Temperament and Character Inventory, in predicting somatization. The Temperament and Character Inventory dimensions emerged as distinct and conceptually meaningful predictors for the different SCL-90-R subscales. CONCLUSIONS A broad range of current psychopathology is associated with difficulties in cognitively processing emotional perceptions. Further research needs to clarify whether alexithymia represents a risk factor for mental illness and poorer outcome.

Abstract
This article discusses the promise and problems associated with integrating research on child temperament and research on childhood psychopathology. Unfortunately, these 2 extensive and influential areas of psychological research with children have largely been conducted independently of each other. This article provides a summary of the disciplinary, conceptual, and methodological issues that have hampered an integration of these 2 important bodies of research. It also highlights the great promise that such an integration could have for advancing causal theories of childhood disorders and for eventually improving the treatment provided to children with serious emotional and behavioral disturbances.

Abstract
BACKGROUND Certain aspects of the personality may be associated with the vulnerability to develop depression. A sib-pair method has been used to examine the familiality of the 7 scales of the Temperament and Character Inventory (TCI) and whether this could be related to the genetic vulnerability to develop depression. METHODS Probands with depression and their nearest-aged siblings from Wales were compared with healthy control probands and their nearest-aged siblings on the TCI and measures of depressed mood. RESULTS All 7 scales of the TCI were familial, and scores on 6 of the scales were similar to US population scores. However, the Welsh subjects' scores on the self-transcendence scale were markedly lower than the US mean, suggesting strong cultural or national influences on this measure. Harm avoidance scores were substantially influenced by current and past depression, but this scale also showed stable traitlike characteristics that are likely related to the genetic vulnerability to depression. Novelty seeking and self-directedness were also partly state-dependent and were negatively correlated with low mood; high scorers may be resilient to the development of depression. High reward dependence may also protect against the development of depression and is unrelated to mood state. The cooperativeness, persistence, and self-transcendence scales appear to have a limited relationship with the development of depression. CONCLUSIONS Harm avoidance, reward dependence, novelty seeking, and self-directedness have traitlike characteristics that are related to the familiality of depression. Cooperativeness, self-transcendence, and persistence are also familial, but this appears to be unrelated to depression.

Abstract
The authors investigated the link between children's temperament and the development of asthma and allergies. Prospective longitudinal data on children at the ages of 3-5 months, 3-5 years, and 7-9 years were collected. At age 7-9 years, analyses were performed on data for 3 groups of children (n = 42): those with asthma (no allergies), those with allergies (no asthma), and those with neither asthma nor allergies (the control group). Data for children who developed asthma or allergies prior to age 7-9 years were not analyzed. Differences were found in the premorbid period between the control group and the children who later developed asthma or allergies as well as between the asthma and allergy groups. After onset of illness, no temperamental differences were observed between the 3 groups. The study shows the importance of longitudinal design for asthma research.

Abstract
Maternal reports of child temperament were used to develop temperament profiles of school-age children. The subjects were 883 children who were between 4 and 12 years of age. The children's families varied substantially in their socioeconomic status and race/ethnicity. To develop the profiles, the dimensions derived from the School-Age Temperament Inventory were subjected to a second order principal factor analysis with varimax rotation. Pearson chi-squares were used to determine whether sociodemographic variables were proportionally represented among the profiles. Forty-two percent of the children were classified into four temperament profiles. High maintenance and cautious/slow to warm up were deemed as challenging temperaments. Industrious and social/eager to try were mirror images of those profiles and were labeled easy. Some children were both types of challenging or easy profiles. The generalizability of the profiles in relation to the sociodemographic variables of gender, age, race/ethnicity, and socioeconomic status was also examined. Challenging temperament profiles were disproportionately represented by boys, Hispanic children, and those from lower socioeconomic families. Girls were over represented in the group that included both types of easy temperaments. Social/eager to try children were more often from higher rather than lower socioeconomic status families. Clinical applications and research implications for the profiles are discussed. The profiles can be used as exemplars that parents can use to recognize their child's temperament. Further research is needed to explore whether different developmental outcomes are associated with the profiles.
