- (PsycINFO Database Record © 2017 APA, all rights reserved). The aims of the study were (a) to establish norms for the Swedish child self-report and caregiver rating versions of the Junior and Temperament Character Inventory (JTCI) among young adolescents, (b) to investigate its psychometric properties, and © to investigate congruence between children's self-reports and caregivers' ratings of a child's personality. The sample was a general population of 1,046 children ages 12-14 years and 654 caregivers. The JTCI was found to be reliable on all dimensions except Persistence in the child self-report version. Caregivers rated their own children's personalities as more mature than did the children themselves. Caregivers especially overestimated their daughters' self-reported capabilities for self-acceptance and self-efficacy and might have underestimated their daughters' need for emotional support. This highlights the importance of including the child's self-report on personality in both research and clinical assessments. The results also support the importance of age- and gender-separated norms.

- Distribution by age and sex of the dimensions of the Temperament and Character Inventory were assessed cross-culturally for samples in Sweden, German, and 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 co-workers 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 affects 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 Temperament and Character Inventory is an internationally used personality questionnaire based on Cloninger’s psychobiological theory of personality. Given some limitations of Version 9 a revised version was developed. The structural equivalence of the two versions was demonstrated from a cross-cultural perspective with 309 and 173 healthy volunteers from Sweden and Germany, respectively, who completed both versions in one session. In testing for the replicability of the factors across both samples as well as across both versions, an orthogonal Procrustes rotation method was used. The reliability coefficients for the revision were higher than the former version for both samples. The factor structures of the inventory remain highly equivalent across cultures and across versions. The results indicate a cross-cultural transferability of the Temperament and Character dimensions of the inventory. The stability and the validity of the 7-factor model of personality, as suggested by Cloninger, are supported. The Temperament and Character Inventory-Revised represents an important and useful method for the assessment of personality.

Personality and its complexity : An investigation of the Swedish version of the Temperament and Character Inventory
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In former days the descriptions of personality were based on typologies, reflecting the view that people do not change over time and so have a stable, life-long personality type. Later on exclusive categories were created, but during recent times the understanding of personality has changed due to more dimensional and dynamic thinking.Cloninger’s personality theory integrates concepts and research findings from neuroanatomy, neurophysiology of behavior and learning, and from developmental, social and clinical psychology. It is postulated that the behavioural systems of temperament and character are related to two major neural systems for the adaptation of experiences on various levels. The continuous interaction between temperament and character affects the personality development in both directions; temperament impacts upon character and vice versa during life.The development of the TCI was founded on the development of the biosocial theory of personality, which in turn stimulated the further development of the theory. Unfortunately this theory-based approach is not commonly used in the development of personality measurements. The development of a personality questionnaire on the basis of the theory must be viewed as a significant challenge, and this prompted my interest in dealing with and learning more about this personality assessment method.The objectives of this thesis were a critical evaluation of Cloninger’s theory; a test of its applicability in psychiatric science; and an attempt to contribute to its development.The main findings of our investigations can be described as follows:The adaptation of the Swedish version of the Temperament and Character Inventory (TCI) was successful and the seven factor structure of Cloninger’s biopsychological theory of personality theory was mainly confirmed by the Swedish normative data and by cross-cultural comparisons between data from Germany, Sweden and the U.S.A.The results concerning internal consistency and factor structure further underline that the adult version of the TCI is unsuitable for use in adolescents before age of 17 years. For the adolescents the junior TCI is recommended.Furthermore temperament dimensions seem to be more stable over time compared to the character dimensions. The gender and age differences found suggest that both have to be taken into account in research and clinical application.The results from our studies suggested that the Temperament and Character Inventory (TCI) has to be evaluated as a useful tool within the process of validation of diagnosis of a Personality Disorder (PD), especially in clinical practice where it is often difficult to recognise all a patient’s personality disturbances during a short time. Use of the TCI is likely to improve understanding, classification, and subsequently the interpretations in clinical settings.

Tidskriftsartikel (refereegranskat)abstract
- A cohort of 136 Swedish spouse pairs rated themselves and each other with the Temperament and Character Inventory. The data allowed assessment of the reliability of ratings by knowledgeable informants compared to self-rating for this personality test. The reliability of the informant rating was in the expected range, with an average correlation of .58. Agreement was slightly higher for the Temperament dimensions than for the Character dimensions. Additionally, the design allowed evaluation of the similarity between husbands and wives across the seven dimensions measured by the TCI. Correlations between spouses in self-reports were very low for Temperament, with only Harm Avoidance having a statistically significant correlation (.22, p < .05). On the other hand, all three Character dimensions were significantly correlated. These results support the conceptualization of Temperament and Character as separate components of personality. The results are consistent with previous reports on the personality of spouse pairs. Read More: http://www.amsciepub.com/doi/abs/10.2466/02.09.PR0.109.4.231-242?journalCode=pr0

Tidskriftsartikel (refereegranskat)abstract
- The Temperament and Character Inventory (TCI) is a self-report personality questionnaire based on Cloninger's psychobiological model of personality, which accounts for both normal and abnormal variation in the two major components of personality, temperament and character. Normative data for the Swedish TCI based on a representative Swedish sample of 1,300 adults are presented, and the psychometric properties of the questionnaire are discussed. The structure of the Swedish version replicates the American version well for the means, distribution of scores, and relationships within the between scales and subscales. Further, the Swedish inventory had a reliable factor structure and test-retest performance. The results of this study confirm the theory of temperament and character as a seven-factor model of personality.

- In order to establish new norms of the Swedish version of the Temperament and Character Inventory (TCI), data from 2,209 Swedish individuals (age between 13 and 80) was analyzed. The second aim was to evaluate the impact of age and gender on the questionnaire scores. The third aim was to investigate whether the TCI can be meaningfully applied to adolescents in personality assessment as a basis for further research and clinical studies. Age and gender showed independent effects on personality dimensions, which implies that age and gender specific norms have to be established for the TCI. Furthermore, the results in terms of inconsistencies in the correlational and factorial structure, as well as low internal consistency scores in the younger age groups, suggest that the adult version of the TCI should not be applied below the age of 17; for these age groups we recommend the use of the junior TCI (JTCI). The inventory is under further development and several items are in need of revision in order to create less complicated formulations, enabling an improvement in the psychometrics.

Tidskriftsartikel (refereegranskat)abstract
- Background: The nature of the relationship between personality and bipolar affective disorders is an important but unanswered question. Methods: We have studied personality in bipolar patients by using the Temperament and Character Inventory (TCI). TCI were administered to 100 euthymic bipolar patients and 100 controls from the normal population.Results: Bipolar patients were significantly higher in harm avoidance (HA) and lower in reward dependence (RD), self-directedness (SD), and cooperativeness (CO) than controls. Bipolar patients are more fatigable, less sentimental, more independent, less purposeful, less resourceful, less empathic, less helpful, less pure-hearted, and have less impulse control than controls. Bipolar II patients are more impulsive, more fatigable, less resourceful, and have less impulse control than bipolar I patients.Limitations: Our results are limited to euthymic bipolar patients and cannot be generalized to affective disorders.Conclusions: Even when clinically euthymic on lithium maintenance, bipolar patients continue to have a characteristic cognitive deficit. This is in agreement with cognitive theories about cognitive deficits in depression that are regarded as important vulnerability factors in mood disorders.

- Objectives: The aim of this study was to examine whether personality i.e. temperament and character interacts with age of onset in bipolar disorder. Methods: Bipolar patients were recruited among in- and outpatients from lithium dispensaries of northern Sweden. Patients were diagnosed according to DSM-IV criteria for bipolar disorder type I and II. Temperament and Character Inventory (TCI) was used for measuring personality. TCI was administered to 100 lithium treated bipolar patients and 100 controls. Results: Treatment response was significantly lower (p = 0.005) in patients with early onset compared with late onset. Family history (p = 0.013) and suicide attempts (p = 0.001) were also significantly more common in patients with early onset. Further, patients with early onset were significantly higher (p = 0.045) in the temperament factor harm avoidance (HA) than patients with late onset, but the difference was weak. Patients with early onset had more fear of uncertainty (HA2, P = 0.022) and were more shy (HA3, p = 0.030). Bipolar I patients showed similar results as those in the total bipolar group (I and II), with significantly higher HA (p = 0.019, moderate difference), HA2 (p = 0.015) and HA3 (p = 0.043) in patients with early onset compared with late onset. Bipolar II patients showed no differences between early and late age of onset but the groups are small and the results are therefore uncertain. Conclusions: Early age of onset in bipolar disorder was correlated to an increase in severity, family history, poorer treatment response and poorer prognosis. Early onset was also correlated to personality.

Temperament and character inventory (TCI) was administered to 100 euthymic bipolar patients and 100 controls.Results: Age of onset was significantly lower in patients with suicide attempts in the total bipolar group (I and II) and bipolar I patients compared with patients without suicide attempts. Bipolar (I and II) and bipolar I patients with suicide attempts were significantly higher in harm avoidance (HA) and reward dependence compared with patients without suicide attempts. Patients (I and II) with suicide attempts had significantly more anticipatory worry, fatigability and asthenia than patients without suicide attempts. Bipolar I patients with suicide attempts had significantly more fatigability and asthenia and were more dependent than patients without suicide attempts. HA was lowest in patients with no suicide attempts and no family history of suicide, higher in patients with family history of suicide or patients with suicide attempts, and significantly highest in patients with suicide attempts and family history of suicide. Patients with suicide attempts and family history of suicide had more anticipatory worry, fatigability and asthenia. Bipolar disorder was significantly correlated to HA and suicide attempts to HA and PS. Family history of suicide and gender were significantly correlated to suicide attempts.Conclusions: Age of onset, HA, PS, gender and family history of suicide had a moderate to very strong effect on suicide attempts in bipolar patients.

- Gender specific personality profiles in association with the level of aggressive antisocial behavior in offenders have not been previously investigated. In the present study we analyzed data collected from 65 male and 50 female offenders using structured protocols regarding criminal history (by criminal register data), trait aggression (by the Life History of Aggression (LHA) questionnaire), and personality profiles (by the Temperament and Character Inventory (TCI)). Prison inmates differed significantly on several personality dimensions, most pronouncedly were they characterized with low character maturity (low scores in the Self-Directedness and Cooperativeness dimensions of TCI) when compared to gender and age matched controls of the general population. The majority of offenders scored distinctively high on trait aggression. There were moderate to strong associations between the personality dimensions and each of the subscales of LHA (Aggression, Self-directed Aggression and Antisocial behavior). These associations were stronger in the female offender sample. Trait aggression could be best explained by a model, which included male gender, younger age, high novelty seeking temperament and low character maturity. Our results suggest that therapies aiming at strengthening self-governance and increasing cooperativeness (focusing on character maturity) may alleviate aggressive antisocial behavior in offenders.

Responsibility and Cooperativeness Are Constrained, Not Determined

Tidskriftsartikel (refereegranskat)abstract
- Neurobiological determinism has characterized later decades’ scientific approaches to the notion of free will. Scientists suggest that legal responsibility should be adjusted accordingly. We measured the genetic and environmental effects behind self-reported Self-directedness and Cooperativeness in a nation-wide population-based adolescent twin study. In spite of substantial overall genetic and shared environmental effects on these character scores, individual outcomes in both monozygotic and dizygotic co-twins of probands reporting severe personality problems varied widely into the normal range. Hence, even when constrained by genetic and environmental adversity, self-experienced responsibility and cooperation are not simply genetically determined but, to some extent, malleable.

Temperament and Character in the Child and Adolescent Twin Study in Sweden (CATSS): Comparison to the General Population, and Genetic Structure Analysis
- 2013
-
Ingår i: PLoS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 8:8
-
Tidskriftsartikel (refereegranskat)abstract
- Background The Child and Adolescent Twin Study in Sweden (CATSS) is an on-going, large population-based longitudinal twin study. We aimed (1) to investigate the reliability of two different versions (125-items and 238-items) of Cloninger's Temperament and Character Inventory (TCI) used in the CATSS and the validity of extracting the short version from the long version, (2) to compare these personality dimensions between twins and adolescents from the general population, and (3) to investigate the genetic structure of Cloninger's model. Method Reliability and correlation analyses were conducted for both TCI versions, 2,714 CATSS-twins were compared to 631 adolescents from the general population, and the genetic structure was investigated through univariate genetic analyses, using a model-fitting approach with structural equation-modeling techniques based on same-sex twin pairs from the CATSS (423 monozygotic and 408 dizygotic pairs). Results The TCI scores from the short and long versions showed comparable reliability coefficients and were strongly correlated. Twins scored about half a standard deviation higher in the character scales. Three of the four temperament dimensions (Novelty Seeking, Harm Avoidance, and Persistence) had strong genetic and non-shared environmental effects, while Reward Dependence and the three character dimensions had moderate genetic effects, and both shared and non-shared environmental effects. Conclusions Twins showed higher scores in character dimensions compared to adolescents from the general population. At least among adolescents there is a shared environmental influence for all of the character dimensions, but only for one of the temperament dimensions (i.e., Reward Dependence). This specific finding regarding the existence of shared environmental factors behind the character dimensions in adolescence, together with earlier findings showing a small shared environmental effects on character among young adults and no shared environmental effects on character among adults, suggest that there is a shift in type of environmental influence from adolescence to adulthood regarding character.

The Genetic Structure of Cloninger's Psychobiological Model of Personality in Adolescence
- 2012
-
Ingår i: Biological Psychiatry. - 0006-3223 .- 1873-2402.
-
Konferensbidrag (refereegranskat)abstract
- Background: Cloninger’s psychobiological model is based on differences between procedural versus propositional learning, leading to the distinction between four temperament and three character dimensions. In contrast to Cloninger’s original theory, association studies and quantitative genetic studies have suggested at least equally (if not more) importance of genes and genetic effects behind characterdimensions as compared to temperament dimensions. We aimed to investigate the genetic structure of Cloninger’s model in a large population-based study group of adolescent twins to capture the developing personality. Methods: To understand which factors contributed to the seven TCI dimensions, we conducted univariate genetic analysis, using a model-fitting approach with structural equation-modeling techniques. Subjects: 831 monozygotic (MZ) or same-sex dizygotic (DZ) twin pairs aged 15 completed the Temperament and Character Inventory (TCI). Results: Three of the four temperament dimensions (Novelty Seeking, Harm Avoidance; Persistence) showed genetic contributions and unique environmental effects, supporting the original theoretical assumption and previous studies. As predicted by theory, all three character dimensions could be referred to genetic, common environmental, and unique environmental factors, with a considerably lower degree of genetic determinance (see Table 1). Conclusions: In contrast to previously published findings, the results presented here support the robustness of the original TCI structure.

Tidskriftsartikel (refereegranskat)abstract
- 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.

- BACKGROUND: The character higher order scales (self-directedness, cooperativeness, and self-transcendence) in the temperament and character inventory are important general measures of health and well-being [Mens Sana Monograph 11:16-24 (2013)]. Recent research has found suggestive evidence of common environmental influence on the development of these character traits during adolescence. The present article expands earlier research by focusing on the internal consistency and the etiology of traits measured by the lower order sub-scales of the character traits in adolescence. METHODS: The twin modeling analysis of 423 monozygotic pairs and 408 same sex dizygotic pairs estimated additive genetics (A), common environmental (C), and non-shared environmental (E) influences on twin resemblance. All twins were part of the on-going longitudinal Child and Adolescent Twin Study in Sweden (CATSS). RESULTS: The twin modeling analysis suggested a common environmental contribution for two out of five self-directedness sub-scales (0.14 and 0.23), for three out of five cooperativeness sub-scales (0.07-0.17), and for all three self-transcendence sub-scales (0.10-0.12). CONCLUSION: The genetic structure at the level of the character lower order sub-scales in adolescents shows that the proportion of the shared environmental component varies in the trait of self-directedness and in the trait of cooperativeness, while it is relatively stable across the components of self-transcendence. The presence of this unique shared environmental effect in adolescence has implications for understanding the relative importance of interventions and treatment strategies aimed at promoting overall maturation of character, mental health, and well-being during this period of the life span.

- In this study the American, Swedish, and German versions of the Temperament and Character Inventory were compared based on samples of 330 healthy volunteers each, which had been carefully matched for age and sex. The analyses indicate a high agreement for scores on the temperament and character dimensions and subscales across the samples. Exceptions include minor differences that appear to be due to cultural variations, differences in sampling methods, and of some minor difficulties with two subscales (Exploratory Excitability and Self-acceptance) as well as defining the Persistence factor as an independent dimension of Temperament. The subscales yielded similar internal consistencies, correlational structure, factor structures, and high factor congruence coefficients. The results indicate a cross-cultural transferability of the Temperament and Character dimensions of the inventory. Also, the validity and stability of the seven-factor model of personality, as suggested by Cloninger, is supported.

- Personality disorders (PDs) criteria are still in development. Cloninger's biosocial theory of personality contributed to this discussion. The aim of the study was to explore the relationships between extreme expressions on temperament and an immature character according to Cloninger's assumptions. Eight hundred healthy volunteers and 200 psychiatric inpatients were consecutively recruited each from Sweden and Germany, and were asked to complete the Temperament and Character Inventory, which measures 4 temperament and 3 character dimensions. Patients differed from controls on temperament and character dimensions. The combination of low and very low character scores with extreme scores in either novelty seeking, harm avoidance, or reward dependence was found more often among patients with PD compared with patients without PD and controls; this is more pronounced with an increasing number of extreme temperament scores. The Temperament and Character Inventory represents a useful tool in the diagnostic process of personality disorders.

- The aim of the study was a cross-cultural comparison of personality traits between individuals from two very different cultures and refugees who resettled several years before from one to the other. Four hundred forty four Swedish individuals of the normal population, and 100 Iranian refugees in Sweden, and a group of 335 individuals from Tehran, capital of Iran, were investigated by means of the Temperament and Character Inventory, a questionnaire to assess temperament and character. Iranians are those that are most frequently correctly classified followed by the Swedish based on temperament scores by means of a Discriminance analyses. Iranian refugees in Sweden were classified to about 50 per cent as Swedish and to slightly more then one-third as Iranians. Especially concerning character, 4 per cent only could be correctly classified as refugees. The results give some perspective on the adaptation process and personality changes in refugees several years after resettlement in another country with a complete different culture.

- Objective To study the personality characteristics of identifiable oocyte donors in a national sample in comparison with normal values. Design Descriptive study. Setting All Swedish donation programmes. Sample In total, 181 women out of 221 donors recruited during 2005-2008. Methods Standardised questionnaires were used to measure personality characteristics. Main outcome measure Demographics, temperament and character inventory (TCI). Results The majority (69%) of the donors had biological children of their own. The results from the TCI indicate that the oocyte donors were all within the normal range of character. With regard to personality, a significant difference was evident between the two groups: oocyte donors showed lower means for harm avoidance and higher scores for persistence than the controls. This indicates that the donors felt less worried, and displayed a lower level of fear of uncertainty, shyness and fatiguability, and a higher level of persistence, than the controls. In the present sample, 29 (16%) of the donors were so-called 'known donors', that is the recipient couples and the donors were known to each other. 'Known donors' displayed a mature and stable character. Conclusion We found that the women who had been accepted for inclusion in this nationwide oocyte donor programme were all well adjusted and mature.

About one-third (36.5%) of the donors had biological children of their own. With regard to personality, significant differences were present on harm avoidance, with lower means for sperm donors (P = 0.002, 95% CI -3.74 to -0.85), and on self-directedness and cooperativeness, with higher means for donors (P = 0.002, 95% CI 0.97-4.19; P = 0.001; 95% CI 0.75-2.95, respectively), compared with controls. This indicates that the donors in general feel less worried and suffer less from uncertainty, shyness and fatigability than controls. They also perceive themselves as being autonomous, with a capacity to take responsibility, to behave in a goal-directed manner, to be resourceful and sel-facceptant, and to behave in a manner guided by meaningful values and goals. Furthermore, they describe themselves as being well integrated in humanity or society, and having a good capacity for identification with and acceptance of other people. less thanbrgreater than less thanbrgreater thanConclusions The screening process at the clinics seems to generate a group of stable, mature and well-integrated donors, and this is a promising result for the future.
