Sensation seeking in major depressive patients: Relationship to sub-threshold bipolarity and cyclothymic temperament

BackgroundHigh levels of sensation seeking (SS) have been traditionally reported for lifetime bipolar disorder (BD) and/or substance use disorder (SUD) rather than major depressive disorder (MDD). Nonetheless, a renewed clinical attention toward the burden of sub-threshold bipolarity in MDD, solicits for a better assessment of “unipolar” major depressive episodes (MDEs) via characterization of putative differential psychopathological patterns, including SS and predominant affective temperament. MethodsTwo hundred and eighty currently depressed cases of MDD and 87 healthy controls were screened using the Zuckerman's sensation seeking scale-Form-V, the Hypomania Check List-32-item (HCL-32), the Temperament Evaluation of Memphis, Pisa, Paris and San Diego Auto-questionnaire-110-item, the Barratt Impulsivity Scale-11-item, the State–Trait Anxiety Inventory modules and the Structured Clinical Interview for DSM-IV axis-I disorders. Cases were divided into HCL-32+(sub-threshold bipolar)/HCL-32−(“true” unipolar depressed) depending on the HCL-32 total score. ResultsUpon correlation and multivariate regression analyses, the HCL-32+ patients showed the highest levels of SS, higher prevalence of cyclothymic temperament, and higher rates of multiple lifetime axis-I co-morbidities, including SUD. LimitsRecall bias on some diagnoses, including BD, grossly matched healthy control group, lack of ad-hoc validated measures for ADHD, SUD, or axis-II disorders. ConclusionsIn our sample, the occurrence of higher levels of SS in “sub-threshold” bipolar cases outlined a differential psychopathological profile compared to DSM-defined “true unipolar” cases of MDE. If confirmed by replication studies, these findings may aid clinicians in delivering a more accurate diagnosis and a safer use of antidepressants in some MDD cases.

Psychometric properties of the Chinese (Mandarin) TEMPS-A: A population study of 985 non-clinical subjects in China

BackgroundThe TEMPS-A (Temperament Evaluation of Memphis, Pisa, Paris and San Diego) is a 110-item auto-questionnaire (self-rated) which consists of five temperament scales: depressive, cyclothymic, hyperthymic, irritable and anxious temperaments. It has been translated into over 25 languages and validated in at least 12, with broad cross-cultural cogency. This is a first attempt to validate the TEMPS-A in a very large Chinese population speaking Mandarin. MethodsThe Chinese TEMPS-A was adapted from the original English version following a rigorous process of forward translation and backward translation (after the approval of the English back translation by H.S.A. and K.K.A.), it was administered to 985 non-clinical Chinese subjects aged between 18–60 years (53.8% female) in four communities in Guangzhou City, China. A subset of 105 subjects was retested approximately six weeks later. Standard psychometric tests of reliability and validation were performed. ResultsThe test–retest reliability for depressive (0.74), cyclothymic (0.71), hyperthymic (0.67), irritable (0.66) and anxious (0.83) were respectively as shown in the parentheses. For internal consistency, Chronbach alphas coefficients were 0.68, 0.85, 0.82, 0.83 and 0.87, respectively. Exploratory factor analysis revealed 2 super factors, Factor I loading on anxious, cyclothymic, irritable, and depressive temperaments; and Factor II loading on hyperthymic. Depressive, cyclothymic, irritable and anxious temperaments were correlated with each other. Males had significantly higher scores than females for the hyperthymic and irritable temperaments. The prevalence of the dominant depressive (2.9%), cyclothymic (5.6%), hyperthymic (1.3%), irritable (7.0%) and anxious (5.3%) temperaments were respectively as shown in the parentheses. LimitationsAlthough it is likely that generalizability of our scale is good for the entire Mandarin-speaking ethnic composition of China today, future research is needed to establish this conclusively. ConclusionThe Chinese TEMPS-A standardized on one of the largest non-clinical samples in any of the other national studies to date, has good internal consistency, coheres well with validated versions in other languages. The findings suggest that it is a psychometrically sound instrument to assess affective temperaments in clinical and biological studies in China.

2684 – The relationship of affective temeperament and emotional-behavioral difficulties to internet addiction in high school students

Introduction Adolescents with Internet addiction were also shown to have higher scores in neuroticism and psychoticism temperament categories than those of the control group. Objectives There is not a study in the literature addressing the correlation between affective temperament profiles and the Internet addiction. Aims Our aim was to compare the affective temperament profiles and emotional and behavioural characteristics of adolescents with or without the Internet addiction. Methods This is a descriptive and cross-sectional study. It was conducted in a high school. The study sample included 303 students. A sociodemographic characteristics data form, Internet Addiction Scale (IAS), The Strengths and Difficulties Questionnaire (DSQ), and The Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPSA) were used to collect data. Results Of the sample, 6.6% were found to be addicted to Internet. Having a computer in the home (p Conclusions There is a relation between the Internet addiction and affective temperament profiles, especialy with anxious temperament. Furthermore, emotional and behavioural problems are more frequent in adolescents who have problematic Internet use.

Affective Temperaments and Psychopathological Dimensions of Personality in Bipolar and Cyclothymic Patients

The aims of the study were: (1) to study possible associations between temperament, personality dimensions, and psychopathological variables in a clinical sample of euthymic patients with bipolar disorder (BD) and cyclothymia; and (2) to assess how Cloninger's temperament and personality dimensions were associated with affective temperaments. Participants, consisting of 60 patients with BD (type I or II) and cyclothymia in the euthymic phase, completed Akiskal's Temperament Evaluation of Memphis, Pisa, Paris, and San Diego-Autoquestionnaire (TEMPS-A), and Cloninger's Temperament and Character Inventory–revised version (TCI-R). The diagnostic groups differed in past hospitalization, for age at onset of the disorder, and on two affective temperaments: the TEMPS-A Hyperthymia, and the TEMPS-A Irritability. There were six significant associations between affective temperaments and Cloninger's personality dimensions, ranging from 0.26 to 0.54. The measures of Akiskal and of Cloninger tap common behavioral features in patients with bipolar disorder and cyclothymia, yet the differences indicate that the two measures are not redundant. BD and cyclothymic patients differed significantly in temperament and personality, differences that may have important implications for treatment.

Psychometric properties of the Slovenian version of temperament evaluation of Memphis, Pisa, Paris, and San Diego—Autoquestionnaire (TEMPS-A): Temperament profiles in Slovenian university students

BackgroundTEMPS-A (Temperament Evaluation of Memphis, Pisa, Paris and San Diego—Autoquestionnaire) is a self-rated instrument that measures five affective temperaments: depressive, cyclothymic, hyperthymic, irritable, and anxious. The aim of our study was to examine the psychometric characteristics of the Slovenian TEMPS-A and to ascertain if temperament profile is related to the professions chosen by Slovenian students. Methods892 Slovenian university students in six different professional fields (economics, geography, engineering, law, sports pedagogy and nursing) were included in our study. ResultsCronbach's reliability coefficients denoted acceptable internal consistency of the subscales. Principal component analysis revealed relatively good internal structure of the instrument. Nursing and geography students scored the highest on depressive temperament. Sports pedagogues as well as engineers demonstrated the most firm personality structure with distinctive hyperthymic temperament. Law students revealed the most irritable temperament, while nursing and law students scored the highest on anxious temperament. LimitationsSample of Slovenian students is not representative for general population. The structure of the sample was crucial as well, as it comprised mainly of younger students who just started their study. ConclusionsThe Slovenian version of the TEMPS-A proved to have relatively good internal consistency and internal structure. The questionnaire verified as a reliable and valid instrument and generally in line with previous studies. This study strengthens the perspective that professional areas could be associated with distinct affective temperament profile that could influence career decisions. The findings in students of economics, geography, and sport pedagogy are new as they have not been previously investigated by TEMPS researchers. The results open new possibilities for future research.

Occupational stress and psychopathology in health professionals: An explorative study with the Multiple Indicators Multiple Causes (MIMIC) model approach

Occupational stress is a multivariate process involving sources of pressure, psycho-physiological distress, locus of control, work dissatisfaction, depression, anxiety, mental health disorders, hopelessness, and suicide ideation. Healthcare professionals are known for higher rates of occupational-related distress (burnout and compassion fatigue) and higher rates of suicide. The purpose of this study was to explain the relationships between occupational stress and some psychopathological dimensions in a sample of health professionals. We investigated 156 nurses and physicians, 62 males and 94 females, who were administered self-report questionnaires to assess occupational stress [occupational stress inventory (OSI)], temperament (temperament evaluation of Memphis, Pisa, Paris, and San Diego autoquestionnaire), and hopelessness (Beck hopelessness scale). The best Multiple Indicators Multiple Causes model with five OSI predictors yielded the following results: χ2(9) = 14.47 (p = 0.11); χ2/df = 1.60; comparative fit index = 0.99; root mean square error of approximation = 0.05. This model provided a good fit to the empirical data, showing a strong direct influence of casual variables such as work dissatisfaction, absence of type A behavior, and especially external locus of control, psychological and physiological distress on latent variable psychopathology. Occupational stress is in a complex relationship with temperament and hopelessness and also common among healthcare professionals.

P-222 - The 5HTTLPR is associated with bipolar disorder and affective temperaments as measured by TEMPS-A in chinese population

Increasing evidence supports that 5HTTLPR polymorphism of the serotonin transporter gene(5HTTLPR) might associate to bipolar disorder and affective temperaments as measured by TEMPS-A. But the results are discrepant, furthermore, there are no data from Chinese population. The present study was designed to investigate association between 5HTTLPR and bipolar disorder and affective temperaments of patients with bipolar disorder in the specific Chinese population and add new evidence to the field. There hundred and five patients with bipolar disorder and 272 normal controls were included in the present case-control study⌧Temperament Evaluation of Memphis, Pisa, Paris and San Diego -autoquestionnaire version (TEMPS-A) in Chinese was used to assess affective temperament. Chi-square test, T test, Nonparametric test and ANOVA were employed to explore association between 5HTTLPR polymorphism and bipolar disorder and affective temperament of patients with bipolar disorder. 5-HTTLPR L/S polymorphism was associated with bipolar disorder in female (genotype χ 2 = 6.769⌧P = 0.034⌧allele χ 2 = 6.028⌧P = 0.014) and the S allele was associated with anxious temperament (t = 8.248⌧P = 0.005) in patients with bipolar disorder. The LA allele of 5-HTTLPR rs25531 A/G polymorphism was associated with hyperthymic temperament in patients with bipolar disorder (Z = −2.205⌧P = 0.027). 5-HTTLPR might have an effect on the prevalence of bipolar disorder in female and regulate affective temperaments of patients with bipolar disorder in some degree in Chinese population.

Effect of Affective Temperaments Assessed by the TEMPS-A on the Relationship between Work-Related Stressors and Depressive Symptoms among Workers in Their Twenties to Forties in Japan

Relatively recently in Japan, immature-type depression, frequently classified in the bipolar II spectrum, has increased among workers in their twenties to forties. This study explored whether affective temperaments moderate the relationship between work-related stressors and depressive symptoms among this age group. In July 2004, self-administered questionnaires were distributed to all employees of a Japanese company. Eight hundred seventy-four employees (63%) returned the questionnaires, with 728 completed. Questionnaires included the 12-item General Health Questionnaire for assessing depressive symptoms, the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego-Autoquestionnaire version for assessing affective temperaments, the Effort-Reward Imbalance Questionnaire to assess work-related stressors and overcommitment, and questions regarding individual attributes and employment characteristics. Multivariate logistic regression analysis showed that affective temperaments moderated the relationship between work-related stressors and depressive symptoms. Effort (OR = 1.078), which represents job demands and/or obligations imposed on employees, and the upper tertile of overcommitment (OR = 1.589), which represents hyperadaptation to the workplace, were risk factors for depressive symptoms. Additionally, the results for cyclothymic (OR = 11.404) and anxious temperaments (OR = 1.589) suggested that depressive symptoms among this age group may be related to immature-type depression.

P-225 - Affective temperament profile in patients with hypertension. First results with temps-a in primary care in hungary

Introduction Affective temperaments profoundly determine emotional reactivity and are the main precursors of major affective disorders. Having strong genetic and biological basis, they are relatively stable throughout life. Given the strong and multidimensional relationship between affective and cardiovascular disorders, temperaments may be effective predictors of future cardiovascular risks and events. Objectives The assessment of affective temperament profile of hypertensive patients. Aims Explore affective temperaments, anxiety and depression in a hypertensive population in primary care settings. Methods 214 consecutive hypertensive and 90 control subjects completed the Temperament Evaluation of Memphis, Pisa, Paris and San Diego Autoqestionnaire (TEMPS-A), Hamilton Anxiety Scale (HAM-A) and Beck Depression Inventory (BDI). For comparisons, Mann-Whitney U test was applied. Results Hypertensive patients scored significantly higher in both BDI (U = 6854; p = 0,002) and HAM-A (U = 6543; p = 0,004). Hypertensives also had significantly higher (U = 8214; p = 0,029) irritable temperament scores, while there was no significant difference in case of the other temperaments. Controlling for diagnosed depression rendered the effect of irritable temperament on hypertensives only marginally significant (U = 5836; p = 0,053). Conclusions Our results suggest that BDI and HAM-A could be effectively used in primary care for screening patients with high cardiovascular risk. The more marked presence of the irritable temperament in the hypertensive group reveals new information, since it may mediate susceptibility to behavioural risk factors and reaction to stressful life events known to play a role in cardiovascular risk. Exploration the relationship between irritable temperament and Type A behaviour needs further studies.

Affective temperaments in the students of the School OF Physical Education and Sports (Mustafa Kemal University-HATAY TURKEY)

The objective of this study was to investigate temperament features of students of the School of Physical Education and Sports. The design was by Personal Information Form developed by researchers and Temperament Evaluation of Memphis, Pisa, Paris and San Diego – Auto questionnaire (TEMPS-A) Scale developed by Akiskal et al. (1997) were used in this general screening study. The sample group was consisted of a total of 200 volunteers (72 female participants and 128 male participants) studying at Teaching Department, Sports Management Department and Recreation Department of the school. Statistical Package for Social Sciences (SPSS) 16.0 was used to assess the data. Data were summarized in means and standard deviations. One–Sample Kolmogorov–Simirnov test was used to determine normal distribution. Error threshold was accepted as 0.05. The results show the ratio of dominant affective temperaments (8%) in a specific sample without any psychiatric disorders which was found to be similar to those reported in literature. Cyclothymic and anxious temperament was significantly more common in sportswomen. Hyperthymic temperament including leadership features were more common in sports players compared to the general society. Conclusively, defining the temperamental nature of sportsmen might help predicting how they relate to their team members, improving sportive performance and making them psychologically more stable. Key words: Cyclothymic disorder, temperament, occupation, psychology, leadership.

Affective temperaments: from neurobiological roots to clinical application

The Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A) has grown to be a clinically important outcome measure in the diagnosis and the clinical course of mood disorders. However, temperaments, which represent the biologically stable core of personality, are not just antecedents of major affective disorders, but also serve as a reservoir of genetically advantageous traits for the survival of different cultures. The rapidly growing body of research in psychiatric and non-psychiatric fields even raises the question of temperament as a common root in psychiatric and somatic disorders, providing a new meaning for the construct of psychosomatic disorders. In this review we aim to summarize current knowledge on both the neurobiological background and clinical importance of affective temperaments including implications for future research.

Validation of the Brazilian brief version of the temperament auto-questionnaire TEMPS-A: The brief TEMPS-Rio de Janeiro

Over the last thirty years, Akiskal and collaborators have described and developed operationalized diagnostic criteria for five types of affective temperaments - cyclothymic, irritable, hyperthymic, depressive, and anxious. A 110-item, yes-or-no questionnaire, the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego (TEMPS-A), was specifically developed for measuring temperamental variation. The TEMPS-A was translated into more than 25 languages and cross-culturally valid versions are now available in Italian, French, German, Japanese, Turkish, Arabic, Polish, Hungarian, Spanish and Portuguese. Recent studies in the US and in Europe, however, have suggested that shorter versions of TEMPS-A can be just as efficient as the full ones while potentially enhancing the compliance of respondents. The main objective of the present study was to validate a brief Brazilian Portuguese version of TEMPS-A (brief TEMPS-Rio de Janeiro). Our main sample consisted of 997 undergraduate students (female = 72.6%) from seven different universities located in the city of Rio de Janeiro, Brazil. An additional group of 167 healthy senior citizens (women = 83.8%) was recruited in senior community centers in the city of Rio de Janeiro, Brazil. All participants were asked to complete the 110-item, Brazilian translation of the full version of the TEMPS-A. An exploratory factor analysis (PCA type 2, Varimax rotation) vying for a five-factor solution yielded mixed results, with cyclothymic traits, physical symptoms of anxiety and preoccupation with the well-being of a family member loading together on the first factor. When a forced six-factor solution was attempted, cyclothymic, irritable, hyperthymic, and depressive were delineated as predicted by the theory. The original generalized anxious temperament was split into two sharply delimited components, a "worrying" subscale and an abbreviated anxious subscale, which included physical symptoms of anxiety and concerns with the well-being of relatives. Based on the tripartite model of anxiety and depression, we proposed that the abridged anxious subscale, which includes physical symptoms of anxiety, represents the "true" generalized anxious temperament, while the "worrying" subscale corresponds to the "general distress factor". The internal consistency of the six subscales thus identified was generally good, ranging from 0.67 (anxious subscale) to 0.81 (worrying subscale), with cyclothymic, irritable, depressive, and hyperthymic subscales exhibiting intermediate values (0.74, 0.74, 0.72, and 0.7, respectively). The present study was based on a non-clinical sample that does not reflect accurately the characteristics of the Brazilian population. The relative uniformity of the sample in terms of age and education precluded a more in-depth analysis of the influence of these highly relevant factors. Further, we did not assess convergent, divergent or test-retest validity. We believe that the brief Brazilian version of the TEMPS-A auto-questionnaire will provide Brazilian researchers and clinicians with a psychometrically sound instrument and thus contribute toward the creation of a worldwide research network dedicated to the investigation of affective temperaments.

Effect of temperaments on quality of life and social adaptation in depressive patients with mood disorder

The aim of this study was to investigate the effects of temperament on quality of life and social adaptation in depressive patients with mood disorder. Forty-six consecutive depressive outpatients were investigated by using the Temperament Evaluation of Memphis, Pisa, Paris and San Diego-Autoquestionnaire version, the Munich Personality Test, the World Health Organization Quality of Life 26 (WHO QOL 26), and the Social Adaptation Self-evaluation Scale (SASS). The unpaired t-test, Pearson's r and multiple regression analysis were used to assess three variables (age, the number of temperaments and/or personality types, and Hamilton Depression Rating Scale scores) as independent variables with the scores of WHO QOL 26 and SASS as the dependent variables. The number of temperaments and/or personalities and Hamilton Depression Rating Scale scores were significantly and negatively associated with WHO QOL 26 scores while only the number of temperaments and/or personalities was significantly and negatively associated with SASS scores. The findings suggest that the combination of temperaments and/or personality types assessed with the Temperament Evaluation of Memphis, Pisa, Paris and San Diego-Autoquestionnaire version and the Munich Personality Test may worsen both quality of life and social adaptation and that some temperaments and/or personality types in combination may be subclinical manifestations of mood disorders.

Temperament and Character Domains of Personality and Depression

Depression Research and Treatment has issued a second compendium of papers focused on temperament, character, and depression. The psychobiology theory of personality proposed by Cloninger is a currently prevailing theory of personality that has been extensively investigated in the context of many different types of mental and personality disorders. This special issue reports up-to-date research findings on the psychobiology theory and depression from different countries. The current issue consists of six reports. Miettunen and colleagues in Finland present findings from a longitudinal birth cohort study (N = 4941). Participants with depression at 31 years of followup had higher rates of harm avoidance (HA) than participants without any psychiatric disorders. Participants without any psychiatric history were followed for another 12 years. Those who subsequently developed depression had high HA in 1997. The authors hypothesize that high HA is a potential indicator for subsequent depression. This study only used temperament scales and thus no information was available on the association between character and depression. Students in senior high schools (N = 1234) who were invited to participate in an internet-based intervention program for depression were studied by Christian and colleagues in Norway. High HA and low self-directedness (SD) emerged as strong predictors of adolescent depression. Interestingly, use of the internet intervention program was associated with low reward dependence (RD) in addition to depression severity. Garcia and colleagues studied an adolescent population (N = 304) in Sweden. Based on positive affect (PA) and negative affect (NA) scores derived from the Positive Affect and Negative Affect Schedule, the participants were categorized into four groups: self-fulfilling (high PA and low NA), high affective (high PA and high NA), low affective (low PA and low NA), and self-destructive (low PA and high NA). The self-fulfilling group was characterized by higher persistence (PS), SD, and cooperativeness (CO) than the three other groups. The self-destructive group was characterized by high HA and RD. The authors claim character maturity (expressed as high SD and CO) is important for psychological well-being. In Japan, Lu and colleagues followed graduate students (N = 184) on two occasions separated by a five-month interval. In a structural regression model, they posited that trait anxiety and depression constructs were linked to high HA and low SD. Although trait anxiety and depression scores were moderately correlated with each other, these two constructs showed different associations with Temperament and Character Inventory (TCI) subscale scores. Thus, trait depression was linked to high self-transcendence (ST) whereas trait anxiety was linked to low RD, PS, and CO. The authors claim that character maturity is linked to trait rather than state aspects of depression and anxiety. Directly exposed survivors of the Oklahoma City bombing randomly selected from a bombing survivor registry (N = 151) were examined by North and colleagues in the USA. Posttraumatic stress disorder (PTSD) after the bombing was associated with low SD and CO together with high ST and HA. Postdisaster major depression (MD) was more prevalent among those with PTSD than those without it, but low SD and CO could not be predicted by post-disaster MD. The authors emphasized the importance of developing and validating measures of resilience. A unique measure of temperament, the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego (TEMPS), was used by Tei-Tominaga and colleagues to study job stress among employees in one Japanese company (N = 728). Depression was predicted by high levels of cyclothymic and anxious temperament traits even after controlling for the effects of work-related stressors such as demanding work conditions and overcommitment. These articles all indicate the importance of temperament and character traits in the development of depression among a variety of populations across different countries. Despite some differences between the studies, a common theme may be that low SD and high HA are predictors of depression either directly or being mediated by third variables. Toshinori Kitamura C.

Temperamental traits of women applying for a type of job that has been characterized historically by male identity: The military career as case study

BackgroundOver the past fifty years in the Western world the professions and activities that were once practised only by males, are now available to females, too. Affective temperaments, in line with their adaptive function, influence career choices. In general, males and females have proved to have different temperamental profiles. In this study we inquire into the question whether gender differences in temperament have continued unchanged in a field, such as the military career, that has been historically characterized by a male identity. Methods1426 males and 122 females wishing to become a cadet in the Italian Air Force were tested using TEMPS-A[P] (the Temperament Evaluation of Memphis, Pisa, Paris and San Diego self-questionnaire, Pisan version). ResultsUnivariate and multivariate analyses failed to distinguish males from females. Both males and females tend to have a high score on the hyperthymic scale (generally, a typical male temperament) and a very low one on the cyclothymic scale (generally, a typical female temperament), with low scores on the depressive and the irritable scales. ConclusionsThis study supports the idea that different gender-related temperaments are functional to differences in the roles played by males and females during the biological and social evolutionary process.

No association between the serotonin transporter gene polymorphism 5-HTTLPR and cyclothymic temperament as measured by TEMPS-A

Background Temperaments are stable personality traits that can be considered subsyndromal risk factors of psychiatric illnesses. The 5-HTTLPR polymorphism of the serotonin transporter gene has been found to be associated with affective temperaments, particularly the cyclothymic temperament, as measured with the Temperament Evaluation of Memphis, Pisa, Paris and San Diego—autoquestionnaire version (TEMPS-A). In this study we have attempted to replicate this finding in a population-based sample which is five times as large as the sample used in the original study. Methods The 21 items of the cyclothymic subscale of TEMPS-A was filled in by 691 individuals (404 females, 287 males, 18–40 years) randomly recruited from the general population. DNA was isolated from saliva, and the serotonin transporter polymorphism 5-HTTLPR was genotyped using the polymerase chain reaction and fragment analysis. Results No significant association was found between 5-HTTLPR genotype and TEMPS-A score, neither when analysing by an additive allelic model nor when the different genotypes and allelic dominance were examined. Furthermore, no association was observed after gender stratification, or when TEMPS-A was analysed as a dichotomous measure, using a cut-off of ≥ 11 positive item responses. Limitations Although being used in clinical settings, TEMPS-A has not been officially validated in Norway. Conclusions This study suggests that there is no association between the 5-HTTLPR polymorphism and cyclothymic temperament as measured by TEMPS-A.

Affective temperamental profiles are associated with white matter hyperintensity and suicidal risk in patients with mood disorders

Background Patients with white matter hyperintensities (WMH) may be at higher risk for affective disorders and suicide. Affective temperaments may play a significant role in mood disorders. This study aimed to evaluate the eventual association between WMH, affective temperaments and suicidal behaviour in major affective disorder. Methods A total of 318 patients with major affective disorders were consecutively admitted as psychiatric inpatient. A total of 247 were included and given, brain magnetic resonance imaging (MRI) and assessed with the Mini International Neuropsychiatric Interview (MINI), the Beck Hopelessness Scale (BHS), the Hamilton Depression Rating Scale (HDRS 17), the Young Mania Rating Scale (YMRS) and the Temperament Evaluation of Memphis, Pisa, Paris and San Diego (TEMPS-A). Results A total of 48% of patients had periventricular WMH (PWMH) and 39% of them had deep WMH (DWMH). Patients with higher dysthymia and lower hyperthymia (H-DCIA group) were more likely to have higher BHS scores (BHS ≥ 9 = 77% vs. 52%; p > 0.001), more WMH (46% vs. 29%; χ 2 n = 3 = 9.90; p < 0.05), higher MINI suicidal risk (54% vs. 42%; p < 0.05), and more recent suicide attempts (24% vs. 14%; p < 0.05), than patients with higher hyperthymia and lower dysthymia (H-H group). Limitations The small sample size did not allow the generalization of the present findings. Conclusions Differences among temperament groups measured by the TEMPS-A are associated with differences in their MRIs, indicating that different temperament profiles are associated with differences in the subcortical structures of the brain. The implications of the results were discussed.

Cyclothymic and hyperthymic temperaments may predict bipolarity in major depressive disorder: A supportive evidence for bipolar II1/2 and IV

Background The concept of soft bipolar spectrum has not been fully confirmed. The aim of the present study is to investigate the validity of bipolar II1/2 and IV concept. Methods The subjects were 46 consecutive outpatients. The individual temperament of each patient was recorded using the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego-Autoquestionnaire (TEMPS-A). The operational definition of bipolar II1/2 was those who had depression with cyclothymic temperament and that of bipolar IV was those who had depression with hyperthymic temperament. Finally, drug responses were investigated. Results DSM-IV-TR diagnoses were bipolar I (N = 1), bipolar II (N = 9), major depressive disorder (N = 34) and depressive disorder not otherwise specified (N = 2). Excluding one bipolar I patient, who had both cyclothymic and hyperthymic temperaments, patients with bipolar II1/2 (N = 32) and IV (N = 13) as well as bipolar II (N = 9) were classified into the soft bipolar spectrum, although there was considerable overlap. The categorization of soft bipolar spectrum and unipolar depression significantly predicted depressive, cyclothymic, irritable, and anxious temperaments. Moreover, soft bipolar spectrum patients with lithium treatment were significantly more in remission than those without lithium treatment. In addition, more of those with selective serotonin reuptake inhibitors (SSRIs) had a significant tendency to lower remission than those without SSRIs. Limitations This is a cross-sectional study with a relatively small number of subjects. Conclusions The present findings suggest that cyclothymic and hyperthymic temperaments may predict bipolarity, and the validity of bipolar II1/2 and IV concept is supported.

The association between oxytocin receptor gene (OXTR) polymorphisms and affective temperaments, as measured by TEMPS-A

Oxytocin is associated with social interaction, trust, and affectivity. Affective temperaments are traits based on Kraepelin's typological definition of the "fundamental states" of manic-depressive illness. These states can be measured by the Temperament Evaluation of Memphis, Pisa, Paris and San Diego-Autoquestionnaire version (TEMPS-A). The objective of this study is to assess the association between oxytocin receptor gene (OXTR) polymorphisms and affective temperaments. Participants consisted of 493 genetically unrelated, non-clinical Japanese subjects (307 males and 186 females). The Mini-International Neuropsychiatric Interview (MINI) was used to screen and exclude those who had a lifetime diagnosis of schizophrenia or other psychotic disorders. Fifteen OXTR tag single nucleotide polymorphisms (SNPs) were genotyped using TaqMan® or direct sequencing. The Haploview 4.1. software determined the haplotype block structure. Haplotype-based quantitative trait association analysis with Bonferroni correction using PLINK 1.06 software was used to assess the association between haplotypes and the following affective temperaments: depressive, cyclothymic, hyperthymic, irritable, and anxious. Two haplotype blocks were identified on the OXTR. The depressive temperament was significantly associated with the most frequent haplotype GGGTGTC (rs11131149/rs2243370/rs2243369/rs13316193/rs2254298/rs2268493/rs2268491) (corrected P<0.05). This study consisted of participants from a corporation and the effect sizes were small. The findings suggest that an OXTR haplotype is associated with a discrete depressive temperament. Clarification of the biological basis of this temperamental trait may help to elucidate the pathophysiology of depressive disorder.

Six-Year Stability of Affective Temperaments as Measured by TEMPS-A

Background: A number of psychopathological and neurobiological studies on affective temperament have been conducted based on the assumption that temperament is a stable trait. However, few studies have actually assessed the long-term stability of affective temperament. The objective of this study is to evaluate the 6-year stability of affective temperaments as measured by the Temperament Evaluation of Memphis, Pisa, Paris and San Diego – Autoquestionnaire version (TEMPS-A) in a non-clinical adult population. Sampling and Methods: Study participants consisted of 178 Japanese white-collar workers (103 males and 75 females; mean age = 38.5 years, SD = 7.8) who completed the Japanese version of TEMPS-A twice over a 6-year interval, and who did not have either past or current DSM-IV affective, anxiety or psychotic disorders, as diagnosed with the Mini-International Neuropsychiatric Interview. The long-term stability of affective temperaments as measured by TEMPS-A was assessed by analyzing Pearson correlation coefficients for temperament scores over a 6-year period. Results: Temperament scores were moderately to highly correlated over the 6-year period (depressive temperament, r = 0.59; cyclothymic temperament, r = 0.68; hyperthymic temperament, r = 0.82; irritable temperament, r = 0.66; anxious temperament, r = 0.74; p < 0.01 for all values). Pearson coefficients were in the range of 0.61–0.83 for males and 0.51–0.79 for females, while they were 0.56–0.85 for younger and 0.63–0.77 for older participants. All correlations were significant at p < 0.01, irrespective of temperament type, gender and age. Conclusions: Affective temperaments as measured by TEMPS-A exhibited good long-term stability and were robust, irrespective of temperament type, gender and age. Affective temperaments as measured by TEMPS-A may be considered to be stable traits, providing a sound basis for psychopathological and neurobiological studies. Limitations of this study include the fact that our sample was not drawn from the general community, it was entirely composed of Japanese participants and the size was not large.
