Effect of personality dimensions on the diurnal pattern of motor activity

The effects of personality dimensions, age, and gender on 24-hour motor activity patterns were studied in 101 healthy subjects between 20-70 years. We measured motor activity by wrist-actigraphy and personality dimensions by the Tridimensional Personality Questionnaire (TPQ) of Cloninger. Random Regression Models were used to estimate the effects of personality dimensions, age, and gender on the diurnal pattern of motor activity. Harm Avoidance as well as Reward Dependence influenced the overall level of motor activity, independent of age and gender. Subjects high on Harm Avoidance showed lower activity levels than subjects low on Harm Avoidance, whereas subjects high on Reward Dependence had higher overall levels of motor activity than subjects low on Reward Dependence. Older subjects were found to be less active than younger subjects, but the activity level did not differ between males and females.     

Validation of the German version of Cloninger's TPQ: Replication and correlations with stress coping, mood measures and drug use

The tridimensional personality questionnaire (TPQ) was developed by Cloninger (1986, 1987a) to measure the independent personality dimensions Novelty Seeking (NS), Harm Avoidance (HA) and Reward Dependence (RD). After having investigated the basic psychometric properties of a German version of the TPQ in a first study (Weyers et al., 1995), a new sample of 200 subjects was collected to investigate the reliability of the results of this first study and to add further validity data by including measures of stress coping, mood and drug use. In general, the results of the first study were replicated. The internal consistencies of the superscales NS, HA and RD were high, and a factor analysis of the TPQ subscales yielded some support for Cloninger's personality theory. Because of its strong correlations with Psychoticism, Extraversion, Impulsiveness and Sensation Seeking NS seems to tap an impulsivity factor while HA correlates with Neuroticism and Introversion and appears to measure a behavioral inhibition factor, the latter interpretation being supported by correlations between HA and some mood measures like anxiety and self-confidence. In addition, HA showed substantial positive correlations with coping strategies like Rumination, Resignation and Self-pity and substantial negative correlations with strategies like Self-aggrandizement by Comparison with Others and Positive Self-instructions, while the other two TPQ superscales hardly correlate with any of the coping strategies measured. With respect to drug use, only NS showed small but substantial bivariate correlations with the use of nicotine and psychodysleptics for the last 12 weeks and last 2 years. However, a configurational analysis of the TPQ superscales demonstrated that the type II alcoholism pattern proposed by Cloninger (high NS, low HA and low RD) was associated with a strong alcohol consumption.     

Zuckerman-Kuhlman-Aluja Personality Questionnaire (ZKA-PQ) and Cloninger's Temperament and Character Inventory Revised (TCI-R): a comparative study

The aim of this study was to compare the psychometric properties (normal distribution values, reliabilities and factor structure) of the Zuckerman-Kuhlman-Aluja Personality Questionnaire (ZKA-PQ) and the Temperament and Character Inventory revised (TCI-R). The total sample consisted of 482 subjects (53.1% men and 46.9% women) from diverse age. Results showed somewhat better psychometric properties, like reliability and facet-factor structure, for the ZKA-PQ than the TCI-R. The expected five-factor facet structure of the ZKA-PQ was clear found. However, the seven-factor structure of TCI-R was not clear and it did not show a clear distinction between Temperament and Character factors. When ZKA-PQ and TCI-R variables are analyzed together, the ZKA-PQ factors are related to the Character as well as the Temperament factors. In some cases they represent the opposite poles of ZKA-PQ factors; for example, Neuroticism versus Self-Directiveness and Aggression versus Cooperativeness. Some are directly and highly related to ZKA-PQ factors; for example, Sensation Seeking and Novelty Seeking, Extraversion and Reward Dependence, Neuroticism and Harm Avoidance, and Activity and Persistence.     

The genetic and environmental relationship between Cloninger's dimensions of temperament and character

The purpose of this study was to determine whether Cloninger's revised 7-factor model of personality showed incremental validity over his four dimensions of temperament. A sample of 2517 Australian twins aged over 50 between 1993 and 1995 returned completed self-reported measures of Self-directedness, Cooperativeness, and Self-transcendence from Cloninger's Temperament and Character Inventory. Many of these twins had participated in a 1988 study containing Cloninger's temperament measures of Harm Avoidance, Novelty Seeking, Reward Dependence and Persistence. Contrary to theoretical expectations, univariate analyses revealed that familial aggregation for the character dimensions could be entirely explained by additive gene action alone. Although temperament explained 26, 37 and 10% of additive genetic variance in Self-directedness, Cooperativeness and Self-transcendence, respectively, seven genetic factors were required to explain the genetic variance among the TPQ dimensions, and almost all of the non-shared environmental variance was unique to each dimension of character. Our results indicate that the inclusion of all seven dimensions in a taxonomy of personality is warranted.     

Distributions by age and sex of the dimensions of temperament and character inventory in a cross-cultural perspective among Sweden, Germany, and the USA

Distribution by age and sex of the dimensions of the Temperament and Character Inventory were assessed cross-culturally for samples in Sweden, Germany, and the USA. The Temperament and Character Inventory is a 240-item (Sweden, 238-item), self-administered, true-false format, paper-and-pencil test developed by Cloninger and his coworkers based on his unified biosocial theory of personality. The inventory measures the Temperament dimensions Novelty Seeking, Harm Avoidance, Reward Dependence, and Persistence as well as the Character dimensions, Self-directedness, Cooperativeness, and Self-transcendence. The samples consisted of 300 German subjects, 300 Swedish subjects, and 300 U.S. subjects matched by age cohort and sex. Stability of the personality dimensions was evaluated across samples as were their age and sex distributions. We found significant effects of age, sex, and culture in univariate and multivariate comparisons on the personality dimensions. However, several significant differences in the personality dimensions for both European samples appear to be similar compared with those of the U.S. sample. We have to conclude that sex- and age-specific norms for the dimensions of the Temperament and Character Inventory are necessary given the established significant differences.     

The Swedish version of the parent-rated Junior Temperament and Character Inventory (J-TCI)

To evaluate the psychometric characteristics of the Swedish version of the Junior Temperament and Character Inventory (J-TCI), it was sent to parents of 9- and 12-yr.-old twins in Sweden. The final number of responders was 196 parents who rated 92 female and 104 male twin pairs. The inventory of one twin, randomly chosen from each pair, was included in the analyses. Reward Dependence, Persistence, and Cooperativeness were scored higher in girls; Novelty Seeking was higher in the 9-yr.-olds and Persistence in the 12-yr.-olds. Pearson's correlations showed that some dimensions were not statistically independent from each other, even if the covariance was moderate. Internal consistency (Cronbach's alpha) was satisfactory for Harm Avoidance, Novelty Seeking, Self-Directedness, and Cooperativeness (.68-.81), while it was lower in those dimensions that had fewer items. The Swedish parent version of the J-TCI shared about the same psychometric characteristics as found in international samples.     

Cloninger's temperament dimensions and threat, stress, and performance appraisals during different challenges among young adults

ABSTRACT We examined the relationship of Cloninger's temperament factors—Novelty Seeking, Harm Avoidance, Reward Dependence, and Persistence—to perceived threat and stress and performance appraisals during different challenges, i.e., mental arithmetic, the reaction time task, and three public speaking tasks, among 97 young adult men and women. Temperament was measured by the Temperament and Character Inventory. The results showed that, although some of the predictions made by Cloninger's model were confirmed, some were unsupported. The results revealed also some associations between temperament and cognitive appraisals that were intelligible, but not predicted by Cloninger's model. There were considerable domain specificity and gender differences in the associations found. Cloninger's temperament dimensions are related to threat, stress, and performance appraisals, thereby influencing individual's stress vulnerability, adjustment, and personal functioning.     

The effect of inpatient cognitive-behavioral therapy for eating disorders on temperament and character

Personality traits seem to have an important role in the development, clinical expression, course, and treatment response in eating disorders (EDs). We investigated the effects of an inpatient cognitive-behavioral treatment (CBT) on the measures of temperament and character (Temperament and Character Inventory (TCI)) in 149 consecutive patients with EDs. Baseline assessment included anthropometry, the Eating Disorder Examination (EDE), the Beck Depression Inventory (BDI), and the TCI. Treatment was based on the transdiagnostic cognitive behavior theory and treatment of ED, adapted for an inpatient setting. Treatment effects were tested by paired ANOVA, adjusted for covariates. No effects were found on Novelty Seeking, Reward Dependence, and Cooperativeness. Harm Avoidance (F=18.17, p<0.001), Persistence (F=7.71, p=0.006), Self-Directedness (F=27.55, p<0.001), and Self Transcendence (F=16.38, p<0.001) significantly changed after treatment. Changes in TCI scores were wholly dependent on the changes in BDI and EDE, and independent of ED diagnosis and behavior and of BMI changes. We conclude that in ED, a few scales of both temperament and character are significantly modified by CBT, in relation to changes in psychopathology and depression, independently of nutrition. These results are relevant for future studies based on TCI.     

The five and seven factors personality models: differences and similitude between the TCI-R, NEO-FFI-R and ZKPQ-50-CC

The present study tests the relationships between the three frequently used personality models evaluated by the Temperament Character Inventory-Revised (TCI-R), Neuroticism Extraversion Openness Five Factor Inventory - Revised (NEO-FFI-R) and Zuckerman-Kuhlman Personality Questionnaire-50- Cross-Cultural (ZKPQ-50-CC). The results were obtained with a sample of 928 volunteer subjects from the general population aged between 17 and 28 years old. Frequency distributions and alpha reliabilities with the three instruments were acceptable. Correlational and factorial analyses showed that several scales in the three instruments share an appreciable amount of common variance. Five factors emerged from principal components analysis. The first factor was integrated by A (Agreeableness), Co (Cooperativeness) and Agg-Host (Aggressiveness-Hostility), with secondary loadings in C (Conscientiousness) and SD (Self-directiveness) from other factors. The second factor was composed by N (Neuroticism), N-Anx (Neuroticism-Anxiety), HA (Harm Avoidance) and SD (Self-directiveness). The third factor was integrated by Sy (Sociability), E (Extraversion), RD (Reward Dependence), ImpSS (Impulsive Sensation Seeking) and NS (novelty Seeking). The fourth factor was integrated by Ps (Persistence), Act (Activity), and C, whereas the fifth and last factor was composed by O (Openness) and ST (Self- Transcendence). Confirmatory factor analyses indicate that the scales in each model are highly interrelated and define the specified latent dimension well. Similarities and differences between these three instruments are further discussed.     

Assessment procedures for narcissistic personality disorder: a comparison of the personality diagnostic questionnaire-4 and best-estimate clinical judgments

This study examined the degree of correspondence between two assessments for narcissistic personality disorder (NPD) in a mixed clinical and community sample--one using a self-report measure (Personality Diagnostic Questionnaire-4) and the other using clinical judgments derived from an assessment based on the longitudinal, expert, all data (LEAD) methodology. NPD scores demonstrated moderate convergence for the total scores but weak convergence for the individual criteria. The authors also examined the correlates created by each set of NPD scores using Cloninger's Temperament and Character Inventory (TCI). The NPD scores demonstrated areas of convergence (e.g., Cooperativeness, Self-directedness) and divergence (i.e., Harm Avoidance, Novelty Seeking) with these personality scores. These divergences may be due to the wording of certain items on the Personality Diagnostic Questionnaire-4 NPD scale, which may require rewriting if it is to provide an assessment that is more highly convergent with the Diagnostic and Statistical Manual of Mental Disorders NPD construct.     

A psychometric evaluation of the revised Temperament and Character Inventory (TCI-R) and the TCI-140

The psychometric properties of the newest version of the Temperament and Character Inventory (the TCI-R) were evaluated in a large (n = 727) community sample, as was the TCI-140, a short inventory derivative. Facets-to-scale confirmatory and exploratory factor analyses of the TCI-R did not support the organization of temperament and character facet scales within their superordinate domains. Five of the 29 facet scales also displayed relatively low internal consistency (a < .70). Factor analyses of the TCI-140 item set yielded only limited support for hypothesized item-to-scale memberships. Harm Avoidance, Novelty Seeking, and Self-Directedness items, in particular, were not well differentiated. Although psychometrically comparable, the TCI-R and the TCI-140 demonstrate many of the limitations of earlier inventory versions. Implications associated with the use of the TCI-R and TCI-140 and C. R. Cloninger's theory of personality are discussed.     

Adolescents’ Temperament and Character: A Longitudinal Study on Happiness

Personality is considered a major determinant of adults and adolescents Subjective Well-Being (SWB); mainly due to its relation to emotional reactivity, emotional intensity, and to the duration of emotional reactions. However, personality as presented above involves almost only differences in automatic emotional reactions and habits (i.e., temperament). Nevertheless, temperament together with learning experiences from different life events is responsible for what people make of themselves intentionally (i.e., character). The present study examines the relation between temperament and character to SWB at two points in time over a year in an adolescent sample (N?=?109). Adolescents reported personality (The Temperament and Character Inventory; TCI) and SWB at the beginning of the school year (T1). Subjective Well-Being was then again measured at the end of the school year (T2). Temperament (Harm Avoidance and Novelty Seeking) and character (Self-Directedness) predicted SWB at T1. However, only Self-Directedness predicted SWB at T2 and also small but significant changes in SWB at the end of the school year. The inclusion of character in SWB research is discussed.     

Personality differences between alcohol abusers and matched controls: Relation to frontal symptoms and subtypes of addicts

Epidemiological studies usually show a link between personality disorders and addictions. Dimensional models of personality, such as that of Cloninger, are able to diagnose and discriminate between transient dysfunctional behavior styles and relatively more stable traits. Certain brain areas have been proposed, as trait locations, based on their activation. This paper explores differences in personality traits among a sample of alcohol abusers (N= 95) and a control group of non-clinical population (N= 95), matched in sociodemographic variables, using the TCI-R-67 and the FrSBe-Sp. It is hypothesized that such differences are associated with frontal symptomatology. The existence of different subgroups of addicts based on certain combinations of traits is also analyzed. Results showed significant differences in two temperament traits (Novelty Seeking and Harm Avoidance) and a characterial trait (Self-Direction). We also found a correlation with a large effect size between these traits and frontal symptomatology. Cluster analysis classified the participants into several subtypes with different combinations of traits that matched diverse frontal symptomatology. Possible neurobiological explanations of these differences and their importance in the clinical practice are discussed.     

International comparison of Cloninger’s temperament dimensions

Cloninger’s Tridimensional Personality Questionnaire (TPQ) and Temperament and Character Inventory (TCI) have been developed to measure the following temperament dimensions: novelty seeking (NS), harm avoidance (HA), reward dependence (RD) and persistence (P). We used our previous Finnish normative study of the TPQ and TCI (Miettunen et al., 2004) to estimate correction coefficients to convert TPQ scales to comparable TCI scales. Our aim was to compare these corrected temperament dimension scores across 20 countries adjusting for study sample differences in age and gender. In all, some variations were found in these temperament scores between countries. Differences were especially apparent between the Asian and the Western countries. By far the lowest mean score of the RD was in Japan (11.2 vs. 15.4 for other countries; effect size Cohen’s d = −5.74; z-test p < 0.001) and the highest mean score in P was in USA (5.5 vs. 4.4; d = 4.24, p = 0.001). Some of the findings could be explained by sample differences (e.g. age and education); while some may reflect real differences in the ways which personality is related to cultural factors, such as individualism/collectivism. These differences should be considered when interpreting studies with data on TPQ/TCI from different countries.     

Confirmatory factor analysis of the tridimensional personality questionnaire: comments on Bagby, Parker and Joffe

This note is concerned with the interpretation of results of a confirmatory factor analysis of data from the Tridimensional Personality Questionnaire, which has been proposed by Bagby, Parker and Joffe (1992; Personality and Individual Differences, 13, 1245–1246). Contrary to their claim of having found a model providing ‘a remarkably good fit’ between the obtained factor structure and the hypothesized dimensions corresponding to the three dimensional biosocial model of personality proposed by Cloninger, it is argued that the cited fitting evidence does not convincingly point to a tenable model. Issues in structural equation model evaluation, as well as possible reasons for lack of an acceptable fit of the model, are discussed.     

Temperament-Character Profile and Psychopathologies in Patients with Alopecia Areata

The aim of this study is to investigate psychopathologies and the temperament-character profile of Alopecia Areata patients and to compare them with healthy controls. Patients and controls who presented at a dermatology clinic were selected by convenience sampling to respond to Temperament and Character Inventory (TCI), SCL-90-R, and a checklist about the demographic data and their dermatologic and psychiatric history. Patients reported higher harm avoidance and reward dependence than controls (Cohen's d = .93 and = .94). A significant correlation between Harm Avoidance (r = ?0.33, p = .02) and Reward Dependence (r = ?0.28, p = 0.05) with sex was found (females scored higher). Lifetime history of AA relapse was significantly associated with higher psychiatric symptoms; the effect sizes were large for Obsessive-Compulsive (d = .81) and Paranoia Ideation (d = .89). The higher psychological symptoms in AA patients with the history of relapses in this study have a practical message for clinicians.     

Individual differences in relatedness and individuality: An exploration of two constructs

Sociotropy and autonomy are two personality dimensions that relate to an individual's vulnerability to depression. Independent and interdependent self-construals are two distinctive cognitive formulations of the self derived from cross-cultural research. Both of these sets of constructs reflect self and other orientations. The purpose of the present study was to empirically examine the various factors that emerge when these two constructs are integrated. 652 participants responded to the Personal Style Inventory [Robins, C. J., Ladd, J., Welkowitz, J., Blaney, P. H., Diaz, R. & Kutcher, G. (1991). The Personal Style Inventory: Preliminary validation studies of new measures of sociotropy and autonomy. Journal of Psychopathology and Behavioral Assessment, 16, 277–300.], the Sociotropy-Autonomy Scale [Clark, D. A. & Beck, A. T. (1991). Personality factors in dysphoria: A psychometric refinement of Beck's Sociotropy-Autonomy Scale. Journal of Psychopathology and Behavioral Assessment, 13, 369–388.] and the Self-Construal Scale [Singelis, T. M. (1994). The measurement of independent and interdependent self-construals. Personality and Social Psychology Bulletin, 20, 580–591.]. Four factors emerged from a factor analysis conducted on the items of the three scales measuring sociotropy-autonomy and independent and interdependent self-construal. These four factors are discussed in the context of vulnerability to depression.
