Background: Developmental studies of temperament and character dimensions are crucial for a better understanding of how genetic and environmental factors interact in shaping individual personality. However, although several studies have been conducted in adults, a few studies have addressed the evaluation of temperament and character in children. Here, we tested the suitability of self-report evaluation and the developmental trend of temperament and character dimensions among school-aged children using an Italian version of the junior Temperament and Character Inventory (jTCI). Methods: The jTCI was completed by 572 Italian children (292 girls and 280 boys) aged 8 to 12 years. We evaluated the internal consistency of the 7 jTCI scales at each age, the intercorrelations between the scales, and the factorial model of the questionnaires. Furthermore, we tested the differences between the development of the temperament and character dimensions in girls and boys. Results: Although the data from 8-year children showed unacceptably low internal consistency, better reliability was observed for older children. Intercorrelations and factor analysis partially confirmed the hypothesized structure of the jTCI items, with problems observed for some items of the Novelty Seeking, Harm Avoidance, Reward Dependence (RD), and Self-Directedness scales. Furthermore, in keeping with previous studies, girls presented lower scores in Novelty Seeking and higher RD, Self-Directedness, and Cooperativeness scales than did boys, with the between-sex difference in RD becoming larger at older ages. Conclusions: Although the use of the self-administered jTCI in clinical settings should be cautious, it may serve as a useful complementary instrument to describe the development of personality in childhood.
Individual differences in preschool children: temperament or personality?
Infant and Child Development, 2010
Individual differences among adults have generally been conceptualized in terms of personality theory and traits. In contrast, individual differences among very young children (birth to kindergarten) have generally been conceptualized in terms of temperament theory and traits. The present study compares and contrasts measures of temperament and personality in a sample of preschool children. Temperament traits were assessed with a well-established measure (the Rothbart CBQ), and a new preschool rating instrument was used to assess personality traits from the five-factor framework (M5-PS). Indeed, a key purpose of this study was to further the development of the M5-PS. Data were gathered on 122 preschool children who were rated by their teachers. Significant correlations were found between the temperament trait Surgency and the personality trait Extraversion, between the temperament trait Negative Affect and the personality trait Neuroticism, and between the temperament trait Effortful Control and the personality trait Conscientiousness. The overall pattern of correlational data suggests that individual differences in preschool children can be adequately described using the five-factor theory, and that this framework may effectively subsume traditional theories of temperament. Preliminary support for the reliability and validity of the M5-PS is offered.
Cross-cultural assessment of childhood temperament
European Child & Adolescent Psychiatry, 2002
s Abstract The Emotionality Activity Sociability (EAS) questionnaire focuses on heritable individual differences in reactivity and behavior which are often referred to in developmental temperament research. Psychometric properties of the French version of EAS were examined in a sample of 197 school-children aged six to 12 years. Parents, teachers and children aged nine years and more completed parallel forms of the EAS questionnaire. Confirmatory factor analysis was used to examine the fit between the original factors and the data. Internal consistency of each subscale, inter-rater and external validity were also examined. Children-rated EAS showed the best indices of fit between the four hypothesized factors and the data, but internal consistency was generally lower than in adult-rated questionnaires. Shyness and sociability showed significant overlap in both parent and teacher-rated EAS. The low concordance between childand adult-ratings indicates that temperament evaluation and interpretation of items may be influenced by subjective and/or developmental factors. Results are discussed in the perspective of validity versus cross-cultural comparability of temperament measurement. The theoretical four-factor structure was not completely replicable in our sample.
The reliability and validity of the junior temperament and character inventory
Comprehensive …, 2004
The purpose of this study was to evaluate the reliability and validity of the Junior Temperament and Character Inventory (Junior TCI), a child and adolescent version of the Adult Temperament and Character Inventory (TCI), which is based on Cloninger’s biosocial model of personality. The Junior TCI was translated into Korean and administered to 663 Korean middle school students (male/female, 360/303; age, 13.3 ± 1.0 years) and their parents (mother/father, 444/84). Internal consistency was calculated by Cronbach α. A test-retest study of the Junior TCI was conducted across a 3-month interval with 97 subjects. Factor analyses for the temperament and character dimensions were performed using principal component analysis, rotating factors by Promax. Cronbach α values of the Junior TCI scales ranged from .48 to .80 for the temperament scales and from .64 to .68 for the character scales. Test-retest correlations ranged from .62 to .85 for the temperament scales and from .76 to .79 for the character scales. Principal component factor analyses showed three factors out of four temperament scales (Harm Avoidance 1 to 4; Novelty Seeking 1 to 4; Persistence; and Reward Dependence 1, 3, 4) and three factors out of three character scales (Self-Directedness 1 to 5; Cooperativeness 1 to 5; and Self-Transcendence 1 to 3) that were similar to factor structures of adult versions of the TCI. Explorative factor analysis with a condition of eigenvalue greater than 1 produced six factors, as compared to seven factors extracted in Cloninger’s original report of the adult TCI. In conclusion, this was the first study to tests and report detailed psychometric properties of the Junior TCI. The current study confirms that the Junior TCI has satisfactory psychometric properties for the use in child and adolescent populations and reflects Cloninger’s biosocial model of personality.

The lack of empirical research relating temperament models and personality hinders conceptual integration and holds back research linking childhood traits to problem behavior or maladjustment. This study evaluates, within a sample of 443 preschoolers, the relationships between children's maladaptation and traits measured by three temperament models (Thomas and Chess, Buss and Plomin, and Rothbart), and a Five-Factor based personality model. Adequate reliabilities and expected factor structures are demonstrated for most scales. A joint principal component analysis combining 28 temperament and 18 personality scales indicates a six-factor model, distinguishing Sociability, Activity, Conscientiousness, Disagreeableness, Emotionality, and Sensitivity. Regression analyses reveal that although single temperament and personality scales explain from 23% to 37% of problem behavior variance, the six components explain from 41% to 49% and provide a clearer differentiation among CBCL-problem scales. This age-specific taxonomy refines and corroborates conclusions based on narrative reviews and furnishes a more balanced view of trait-maladjustment relationships.
Psychometric properties of a French version of the junior temperament and character inventory
European Child & Adolescent Psychiatry, 2009
The junior temperament and character inventory (JTCI) has been developed for the assessment of temperament and character dimensions in childhood based on Cloninger’s model of personality. We evaluated the psychometric proprieties of a French child and parent-rated version of the JTCI based on a previous German version, and assessed the correlations between the JTCI dimension scores and the scores on the child behavior checklist (CBCL) in a community sample of French children and adolescents aged 10–16 years. We used data from 452 child-rated and 233 -parent-rated JCTI. The psychometric properties (internal consistency and external validity in relation to the emotionality activity sociability (EAS) questionnaire) of the French JTCI were adequate in the parent-rated version. The parent-rated JTCI had overall better psychometric qualities than the child-rated version, but for both versions of the JTCI the confirmatory factor analysis showed low fit between the observed data and the original model. Dimensions of the EAS model were significantly correlated with the temperament scales of the JTCI. Further studies are required to improve the psychometric properties of the child-rated JTCI, and to provide insight about lacking fit of our data with the theoretical model.

The numerous temperament and personality constructs in childhood impede the systematic integration of findings on how these individual differences relate to developmental psychopathology. This paper reviews the main temperament and personality theories and proposes a theoretical taxonomy representing the common structure of both temperament and personality traditions within one conceptual framework. This integrated lexicon of childhood temperament/personality traits facilitates an overview of the most important research findings on the role of temperament and personality in the development of anxiety, depression, ADHD, proactive and reactive antisocial behavior. Several directions for future research are discussed to further validate and refine these reviewed relationships.
Multimethod Longitudinal Assessment of Temperament in Early Childhood
Journal of Personality, 2007
The present study examined consistency of temperament across situations and time in early childhood. On two occasions, 7 months apart, we observed the responses of 94 four-year-olds to multiple standard laboratory procedures eliciting exuberance, fear, anger, sadness, or interest. In addition, fathers' and mothers' reports on children's temperament were obtained. Observed temperament showed substantial context specificity, varying across situations within dimensions. Structural equation models revealed separate observation and parental perception factors and factorial invariance and high stability for most dimensions. Stability coefficients based on correlations varied according to level of aggregation. Measurement convergence was generally moderate and was lowest for negative emotionality. Implications for the assessment of temperament are discussed in relation to differences in consistency across dimensions and convergence between measures.
