The relation between temperament and anger response among prisoners: comparison of Reinforcement Sensitivity Theory and the Psychobiological Model of temperament and character

This study investigates the relation between temperament and anger response among prisoners, and compares temperament as proposed by Reinforcement Sensitivity Theory and the Psychobiological Model of Temperament and Character. We asked 210 prisoners to respond to Korean standardized questionnaires, with items of the Behavioral Inhibition System/Behavioral Approach System (BAS/BIS), and the items of Temperament and character inventory (TCI). Based on the Novaco Anger Scale, prisoners’ anger responses were rated as those of direct, indirect, verbal, or impulsive. Three factors of the BAS and BIS all demonstrated significantly positive correlations, while reward dependence and novelty-seeking from the TCI showed a correlation nearing 0. Also, higher harm avoidance of TCI was associated with lower reward dependence, lower level of persistence, and higher level of novelty-seeking of TCI. Regression analyses showed that impulsive anger reaction was significantly explained by novelty-seeking of TCI and BIS; verbal aggression by fun-seeking of BAS and novelty-seeking of TCI; physical confrontation by novelty-seeking of TCI and fun-seeking of BAS; and indirect expression by novelty-seeking, harm avoidance, and persistence of TCI and fun-seeking of BAS.

Reward Dependence and Harm Avoidance among Patients with Binge-Purge Type Eating Disorders.

The Cloninger's Psychobiological Model of Temperament and Character includes temperamental dimensions such as reward dependence (RD) and harm avoidance (HA). Studies of RD differentiate between sensitivity to reward (SR) versus to punishment (SP). We investigated the interrelationship between HA and RD in acutely ill patients with binge/purge (B/P) type eating disorders (EDs) and following symptomatic stabilization. Fifty patients with B/P EDs were assessed at admission to inpatient treatment, 36 of whom were reassessed at discharge. Thirty-six controls were similarly assessed. Participants completed Tridimensional Personality Questionnaire (TPQ), Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ), and took the Gambling Task. Patients with B/P EDs had higher TPQ-RD and lower TPQ-HA accompanied by lower SPSRQ-SR and SPSRQ-SP. SPSRQ-SP correlated positively and negatively with TPQ-HA and TPQ-RD, respectively. Combination of lower TPQ-HA, lower SPSRQ-SP, and greater risk-taking inclination may maintain disordered eating in patients with B/P EDs.

Standardization and normative data of the Greek version of the temperament and character inventory (TCI).

BackgroundRobert Cloninger’s psychobiological model of temperament and character is a dimensional approach to personality assessment and gave birth to the temperament and character inventory (TCI). The aim of the present report is to examine the psychometric properties of the Greek version of the TCI, and to replicate its postulated structure and provide preliminary normative data for the Greek population.MethodsThe study sample included 734 subjects from the general Greek population (436 females; 59.4 % and 298 males; 40.6 %). Their mean age was 40.80 ± 11.48 years (range 25–67 years). The mean age for females was 39.43 ± 10.87 years (range 25–65 years), while the mean age for males was 42.82 ± 12.06 years (range 25–67 years). Descriptive statistics tables concerning age, gender and occupational status distribution in the sample were created. The analysis included the calculation of Cronbach’s alpha, factor analysis with promax rotation and the calculation of Pearson correlation coefficients between the subscales scores. Analysis of Covariance with age as covariate and t test and Cohen’s d as post hoc tests was used to search for differences in subscales scores between males and females.ResultsThe overall psychometric properties of the Greek version of the TCI proved to be satisfactory, with acceptable consistencies of the subscales. The factor analysis of temperament identified four factors which together explained 58.56 % of total variance, while the factor analysis of the three-factor solution of the character explained 52.24 % of total variance. The TCI scales correlate significantly but weakly between each other and with age.DiscussionThe Greek version of the TCI exhibits psychometric properties similar to its original English counterpart and to other national translations and it is suitable for use in research and clinical practice.

Cloninger’s Psychobiological Model of Temperament and the Discounting of Delayed and Effortful Outcomes Among Adolescents

Cloninger’s Psychobiological Model of Temperament and the Discounting of Delayed and Effortful Outcomes Among Adolescents

Adulthood temperament and educational attainment: A population-based cohort study

The aim of the study was to examine the associations of temperament traits and temperament profiles (i.e., the combinations of multiple traits) with adulthood educational attainment. The participants were 837 women and 592 men from a population-based cohort study. Temperament was assessed with the Temperament and Character Inventory (TCI) based on the Psychobiological Model of Temperament and Character. Analyses were conducted with linear regression analyses and with analysis of variance (ANOVA). In both genders, high harm avoidance was associated with lower educational attainment. High persistence among women and high reward dependence among men were related to higher educational attainment. Novelty seeking was not associated with educational attainment in either gender. Among men explosive and methodical temperament profiles were associated with lower educational attainment while reliable and passionate temperament profiles were associated with higher educational attainment. Temperament may play an important role in lifelong learning and academic performance over different developmental transitions.

Describing Pathological Narcissism in Terms of the Cloninger's Psychobiological Model of Temperament and Character

Introduction Pathological narcissism has been a subject of scientific debates in recent years, with a growing recognition of two phenotypic forms, grandiosity and vulnerability. Because of the lack of consensus on the nature of grandiose and vulnerable narcissism, one way to develop a cohesive literature on pathological narcissism is to investigate it using dimensional models of general personality. Objectives The goal of the present study was to investigate similarities and differences in the relations of narcissistic grandiosity and vulnerability within the Cloninger’s Psychobiological model of temperament and character. Methods A sample of 801 Hungarian adults (72% female; mean age 23.85 years), mostly graduate students, was gathered using a convenience sampling method. The participants completed the Pathological Narcissism Inventory (PNI) and the Temperament and Character Inventory – 60 (TCI-60). Results Narcissistic vulnerability exhibited positive correlations with temperament dimensions Harm avoidance and Novelty seeking and a negative correlation with Reward Dependence, whereas narcissistic grandiosity was positively correlated with Novelty seeking and Persistence. Both features of narcissism had negative correlations with character dimensions Cooperativeness and Self-directedness. However, hierarchical regression analyses demonstrated unique negative associations between narcissistic vulnerability and the abovementioned character dimensions, whereas their relations with grandiosity were non-significant. Conclusions There are various differences in the relations between grandiose and vulnerable narcissism and the seven dimensions of temperament and character. Given that the Cloninger’s model delineates both the core features and distinguishing features of personality disorders, our findings might facilitate more nuanced understanding of pathological narcissism and its more valid diagnostic classifications.

Temperament and Generativity during the life span

This review aimed to collect and discuss a variety of studies that utilized the Temperament and Chatacter Inventory (TCI), an instrument developed by Cloninger in 1993, based on his psychobiological model of temperament and character. Searching on PubMed, 26 from 828 researches has been selected on the basis of four criteria: (a) articles published in English between 1993 and 2013 and identified as empirical or longitudinal studies; (b) reaserches conducted in non pathological sample; (c) measuring temperamental traits or dimensions with the TCI; (d) regarding relevant topics to generativity. Implication for Temperament and character of couples and about the transmission of temperament from parents to children are pointed out. In conlcusion it can be said that TCI is a valid instrument that can describe and predict couples relationship and child temperament and character, until the late adulthood.

Integrating and differentiating aspects of self-regulation: Effortful control, executive functioning, and links to negative affectivity.

Subdisciplines within psychology frequently examine self-regulation from different frameworks despite conceptually similar definitions of constructs. In the current study, similarities and differences between effortful control, based on the psychobiological model of temperament (Rothbart, Derryberry, & Posner, 1994), and executive functioning are examined and empirically tested in three studies (n = 509). Structural equation modeling indicated that effortful control and executive functioning are strongly associated and overlapping constructs (Study 1). Additionally, results indicated that effortful control is related to the executive function of updating/monitoring information in working memory, but not inhibition (Studies 2 and 3). Study 3 also demonstrates that better updating/monitoring information in working memory and better effortful control were uniquely linked to lower dispositional negative affect, whereas the executive function of low/poor inhibition was uniquely associated with an increased tendency to express negative affect. Furthermore, dispositional negative affect mediated the links between effortful control and, separately, the executive function of updating/monitoring information in working memory and the tendency to express negative affect. The theoretical implications of these findings are discussed, and a potential framework for guiding future work directed at integrating and differentiating aspects of self-regulation is suggested.

Character as a predictor of life satisfaction in Czech adolescent sample: 3-Year follow-up study

The study examined personality predictors (based on Cloninger’s psychobiological model of temperament and character – TCI) of life satisfaction in a sample of 15-year-old Czech adolescents (N=173) and subsequently 3years after. The focus of the study was to determine the personality dimensions that predict life satisfaction and how those change over 3years of adolescence. Of all dimensions, significant differences between the two age groups were found only in the character dimensions Self-Directedness and Self-Transcendence. Using stepwise regression analysis, the character scale Self-Directedness alone accounted for 15% of the variance in life satisfaction among 15-year-old adolescents, whereas in the 18-year-old group, 30% of the variance in life satisfaction was explained by the character dimension Self-Directedness and the temperament dimensions Harm Avoidance and Reward Dependence. In both age groups, only Self-Directedness seems to make a unique contribution towards explaining life satisfaction. The results demonstrate that character changes might also account for a great amount of variance in life satisfaction.

Associations between dimensional personality measures and preclinical atherosclerosis: The cardiovascular risk in Young Finns study

ObjectiveTo assess how multidimensional personality–trait theories, such as the Psychobiological Model of Temperament and Character, and the Five-factor Model of Personality, are associated with subclinical atherosclerosis as indicated by carotid intima-media thickness (IMT). The analysis was designed to tolerate non-linear development in which the same personality profiles can have multiple final outcomes and different antecedent profiles can have the same final outcome. Methods605 men and 844 women (average age 31.6year, s.d.=5.0, range=24–39) provided data on IMT and traits of the psychobiological model, 725 men and 1011 women were assessed for IMT and the five-factor model (age 37.7year, s.d.=5.0, range=30–45). Robust multidimensional Hotelling’s T2 statistic was used to detect personality differences between participants with high IMT and others. Model-based clustering method further explored the effect. ResultsThose with a high level of subclinical atherosclerosis within the sample (highest IMT-decile) had a combined higher persistence (i.e., were perseverative or perfectionistic), more disorganized (schizotypal) character, and more antisocial temperamental configuration than others (P=0.019). No effect was found for the five-factor model (P=0.978). Traditional methods that did not account for multidimensionality and nonlinearity did not detect an association. ConclusionPsychological well-being may have positive effects on health that reduce atherosclerosis in the population as a whole. Increased subclinical atherosclerosis was associated with a profile that combines known risk factors, such as cynical distrust and hostile tendencies. More frequent use of statistical procedures that can cope with non-linear interactions in complex psychobiological systems may facilitate scientific advances in health promotion.

Cross-cultural validation of the revised Temperament and Character Inventory: Serbian data

Objective In this work, we report data on construct validity and cross cultural applicability of the revised Temperament and Character Inventory (TCI R) (Cloninger, C.R., Przybeck, T.R., Svrakic, D.M., & Wetzel, R.D. (1999). The Temperament and Character Inventory-revised, Washington University, St. Louis), a 5-point scale scoring formatrevision of the original, true-false version TCI (Cloninger, C.R., Przybeck, T.R., Svrakic, D.M., & Wetzel, R.D. (1994). The Temperament and Character Inventory-A guide to its development and use, Washington University, St. Louis). Both versions are based on the seven factor Psychobiological Model of Personality (Cloninger CR, Svrakic, DM & Przybeck TR (1993). A Psychobiological Model of temperament and Character, Archives of General Psychiatry, 50, 975-990). Methods The sample consisted of 473 normal adult subjects representing a number of Serbian cities and towns, recruited consecutively while registering at the National Employment Center, located in Belgrade, Serbia. The sample was the designed to be highly representative of urban and suburban population in Serbia to match to TCI R sample in the US. The 240-item, 5-point scale scoring TCI R was used to assess temperament and character traits. In addition to a number of other revisions, the scoring format in the TCI R was changed into a 5-point Likert scale to increase its sensitivity to subtle variations in personality expression. The TCI R mean scores and standard deviations were compared between Serbian and US subjects, internal consistency of the TCI R scales was estimated using Cronbach's alpha coefficients, and principal component analysis was used separately for temperament and character (because of their non-linear relationship) to test the underlying factorial structure of the TCI R. Parallel analysis and randomized simulation data were used to determine the number of factors for temperament and character. Results The results generally supported the construct validity and the cross cultural applicability of the TCI R in Serbia. With a few exceptions, the observed internal consistency for the TCI R scales was acceptable. For the most part, the US and Serbian subjects manifested comparable temperament traits, whereas US subjects had higher character scores. The observed differences are understood as partly reflective of local culture and partly of dramatic socio-economic change in Serbia over the last 20 years. Principal component analysis fully supported the four factor structure of temperament and the three factor structure of character, as postulated by theory. The inadequacy of using linear statistical methods in studying complex non-linear systems such as personality is discussed in some detail.

Applying a Psychobiological Model of Personality to the Study of Leadership

Cloninger’s psychobiological model of temperament and character is a general model of personality that has been widely used in clinical psychology, but has seldom been applied in other domains. In this research we apply Cloninger’s model to the study of leadership. Our study comprised 81 participants who took part in a diverse range of small group tasks. Participants rotated through tasks and groups and rated each other on “emergent leadership.” As hypothesized, leader emergence tended to be consistent regardless of the specific tasks and groups. It was found that personality factors from Cloninger, Svrakic, and Przybeck’s (1993) model could explain trait-based variance in emergent leadership. Results also highlight the role of “cooperativeness” in the prediction of leadership emergence. Implications are discussed in terms of our theoretical understanding of trait-based leadership, and more generally in terms of the utility of Cloninger’s model in leadership research.

Impact of the dopamine receptor gene family on temperament traits in a population‐based birth cohort

Although the genetic determinants of personality have been intensively investigated especially since Cloninger proposed his psychobiological model of temperament and character, findings to date remain inconclusive and very few studies have addressed the topic in large population cohorts. In the current study we investigated one gene family in its entirety by addressing the role of all known dopamine receptor genes, DRD1-DRD5, on Cloninger's temperament traits in a Finnish population-based birth cohort. The study sample (n = 1,434) was ascertained from the Northern Finland Birth Cohort 1966 with over 5,000 study individuals tested at the age of 31 years. We utilized the genetic homogeneity and genealogical structure of this population to uncover putative effects of these genes on temperament traits at the population level. Our strategy utilizing a large birth cohort and its well established genealogical structure represents an optimal design for studying normally distributed traits. We also wished to provide a comprehensive view to one biologically relevant gene family instead of testing single candidate genes. We report evidence of association of several SNPs at the 5' end of dopamine receptor D2 (DRD2) with Novelty seeking (low) and Harm avoidance (high), and at the 3' end of DRD2 with Persistence. The strongest evidence of association emerged from females. Our study supports the involvement of the dopamine pathway in temperament traits, in particular underlining the role of DRD2 in Novelty seeking, Harm avoidance and Persistence.

Cloninger's temperament traits and preclinical atherosclerosis: The Cardiovascular Risk in Young Finns Study

Objective Cloninger's psychobiological model of temperament has recently raised interest as a risk factor for CHD. However, there are no studies that have examined the associations of Cloninger's temperament traits with atherosclerosis. Methods The subjects were 398 men and 657 women (mean age 31.7 years) participating in the Cardiovascular Risk in Young Finns Study. Linear regression analyses were used to examine the cross-sectional associations between temperament traits and preclinical atherosclerosis. Preclinical atherosclerosis was measured with carotid intima-media thickness ultrasound. Results Higher novelty seeking (NS) and reward dependence (RD) and lower harm avoidance (HA) were associated with preclinical atherosclerosis. In NS and RD, associations remained significant after adjustments for various risk factors. The effect sizes of these associations were comparable to those of traditional risk factors of coronary heart disease, which is a major finding. No association for persistence (P) was found. Conclusions The present findings imply that examining a wider range of temperament and personality factors may offer new information that can help in explaining the between-individual variation in atherosclerosis and CHD morbidity.

Temperament and character as schizophrenia-related endophenotypes in non-psychotic siblings

BackgroundQuantitative endophenotypes are needed to better understand the pathogenesis of schizophrenia. The psychobiological model of temperament and character suggests that personality traits are heritable and regulated by brain systems influencing schizophrenia susceptibility. Thus, measures of temperament and character may serve as schizophrenia-related endophenotypes in individuals with schizophrenia and their non-psychotic siblings. MethodsIndividuals with schizophrenia (n=35), their non-psychotic siblings (n=34), controls (n=63), and their siblings (n=56) participated in a study of the clinical, neurocognitive and neuromorphological characteristics of schizophrenia. A mixed-model approach assessed group differences on the Temperament and Character Inventory (TCI). Neurocognitive deficits and psychopathology were correlated with the TCI. Configurations of TCI domains were examined using a generalized linear model. ResultsIndividuals with schizophrenia and their non-psychotic siblings had higher harm avoidance than controls and their siblings. Individuals with schizophrenia had lower self-directedness and cooperativeness, and higher self-transcendence than their non-psychotic siblings, controls, and the siblings of controls. Neurocognition was not related to temperament and character in individuals with schizophrenia or either control group. In non-psychotic siblings, self-directedness and cooperativeness were correlated with working memory and crystallized IQ. ConclusionEvidence supports harm avoidance as a schizophrenia-related endophenotype. An increased risk of schizophrenia may be associated with asociality (configured as high harm avoidance and low reward dependence), schizotypy (configured as low self-directedness, low cooperativeness, and high self-transcendence), and neurocognitive deficits (poor executive functioning, working/episodic memory, attention, and low IQ). The non-psychotic siblings demonstrated features of a mature character profile including strong crystallized IQ, which may confer protection against psychopathology.

Body size at birth and socio-economic status in childhood: Implications for Cloninger's psychobiological model of temperament at age 60

Small birth size predicts various psychiatric outcomes, including depression. While biologically based temperamental traits may constitute a vulnerability factor for depression, the extent to which birth size predicts these traits in adulthood is not known. We studied, in 1369 women and men identified from a cohort born in 1934–44 in Helsinki, Finland, whether birth size predicts the temperamental traits measured with Cloninger's Tridimensional Personality Questionnaire at an average age of 63 years. Moreover, we examined whether socio-economic status (SES) in childhood modified the associations. Data on birth size were obtained from birth records, and SES in childhood was obtained from school records. Weight and length at birth showed curvilinear, reverse J-shaped effects on harm avoidance (HA), such that the highest HA scores were most characteristic of those born small. Furthermore, high HA was confined to those belonging to a low SES group in childhood regardless of birth size, and to those belonging to the high SES group in childhood if their birth size was small. The associations were independent of several confounders. Since small birth size as well as high HA in adulthood may associate with subsequent depression, our findings might shed light on understanding the early neurodevelopmental processes that predispose to depression through vulnerability characteristics.

Cross cultural comparison of JTCI inventory of temperament and character scores of 11-13 year olds

The study compares characteristics of Serbian and American children on the dimensions of temperament and character on the Junior TCI (JTCI) for assessment of 9 to 13 year olds - based on Robert Cloninger?s Psychobiological model of temperament and character. Given the lack of assessment tools for this age group, the goal of the present study was to test the factor structure and main psychometric characteristics of the JTCI in order to determine the applicability of this questionnaire on Serbian children. The sample consisted of 222 boys and girls from the normal population, ages 11 to 13 and who attended grades 6 to 8. The results showed significant differences between Serbian and American sample. Namely, Serbian children had higher scores on the Novelty seeking and Harm Avoidance and lower scores on Reward Dependence and Persistency. As to the Character Dimensions, Serbian children had lower scores on Reward dependence and persistency, and significantly lower on Self-directedness and Cooperativeness. Scores on the Self-transcendence were higher among the Serbian children. The differences on Character dimensions between children from different cultures suppose to be primarily a result of the socialization process. They reflect a lower level of maturity, cooperation and probably compensatory reliance on the religion. Although it is a temperament dimension, being prone to negative emotions (higher scores on Danger avoidance) may also be a result of a situational sensitivity. This result could be interpreted as a reflection of the negative effects that the general socio cultural milieu had on the children who grew up during the social crisis and transitional periods of our society. The result did not confirm a seven factor personality structure of children in this age group. It is likely that at the age of 11 to 13, dimensions of character and temperament did not yet clearly differentiate. Finally, poor reliability of the JTCI scales imposes limitations on valid interpretation of these results. It also points out that using this questionnaire on Serbian children is limited unless necessary psychometric modification is conducted.

Temperament and character in primary insomnia

Recent studies by Cloninger suggest that the temperament dimension of harm avoidance might be related to serotonergic activity. Since serotonergic mechanisms equally play a major role in sleep regulation, we decided to use Cloninger’s psychobiological model of temperament and character to assess whether there is a link between psychophysiologic insomnia and specific personality traits. Chronic insomnia is a common complaint in modern society, and it is still controversial whether insomniacs share specific personality traits. Thirty-two chronic insomniacs (<50 years) were studied. They underwent polysomnography for two consecutive nights and filled out the 226-item self-questionnaire of Temperament and Character Inventory as well as the Hospital Anxiety and Depression scale. (1) Harm avoidance for all subscores was significantly higher in insomniac patients when compared with controls; (2) self-directedness scores were lower in insomniacs; (3) sleep latency was positively correlated to harm avoidance; (4) HA1 (anticipatory worry) was negatively correlated to REM latency. Temperament and Character Inventory is a useful tool in the investigation of chronic insomnia. Serotonergic mechanisms might explain the high incidence of harm avoidance as personality trait in psychophysiologic insomniac patients. Further studies are needed to see whether harm avoidance could be a psychological vulnerability marker for primary insomnia and be used as predictor of SSRI treatment responders.

Cloninger's temperament dimensions and affective responses to different challenges

Cloninger's psychobiological model of temperament and character postulates that each of the temperament dimensions is associated with a specific emotional experience, depending on the situational cues. The aim of the present study was to test this postulate in a variety of challenging experimental tasks. The participants were 91 healthy young adults whose temperament was assessed with the temperament and character inventory. The subjects rated their emotions during each task and rest period using an adjective checklist. Novelty seeking was associated with dullness during monotonous and aversive situations and with a higher level of pleasantness during the initial baseline period and the appetitive situation. Harm avoidance was associated with higher levels of fear and unpleasant emotions and lower levels of positively valenced emotions. The present study provides support for the validity of Cloninger's temperament dimensions as predictors of emotional responses during different challenges. Especially, novelty seeking and harm avoidance appear to have a significant influence on emotional experience.

Psychobiological model of temperament and character: Validation and cross-cultural comparations

The paper presents research results regarding Psychobiological model of personality by Robert Cloninger. The primary research goal was to test the new TCI-5 inventory and compare our results with US normative data. We also analyzed the factor structure of the model and the reliability of basic TCI-5 scales and sub-scales. The sample consisted of 473 subjects from the normal population, age range between 18-50 years. Results showed significant differences between Serbian and American samples. Compared to the American sample, Novelty seeking was higher in the Serbian sample, while Persistence Self-directedness and Cooperativeness were lower. For the most part results of the present study confirmed a seven factor structure model although some sub-scales did not coincide with basic dimensions as predicted by the theoretical model. Therefore certain theoretical revisions of the model are required in order to fit in the empirical findings. Similarly, the discrepancy between the theoretical and empirical was also noticed regarding the reliability of TCI-5 scales. They also need to be re-examined. Thus the results of the study showed satisfactory reliability of Persistence (.90), Self-directedness (.89) and Harm avoidance (.87), but low reliability of the Novelty seeking (.78), Reward dependence (.79) and Self-transcendence (.78).
