Objective: Junior Temperament and Character Inventory (J-TCI) was developed by Luby, Svrakic, McCallum, Przybeck, and Cloninger based on Cloninger’s biopsychosocial model to assess temperament and character dimensions in children and adolescents.
Methods: The Turkish version of J-TCI-Revised (J-TCI-R) was administered to 1129 elementary and middle-school (male/female, 546/583) students. Internal consistency reliabilities were measured by Cronbach’s alpha; test–retest was assessed across one month.
Results: Cronbach’s alphas for the subscales of J-TCI-R ranged from 0.60 to 0.75 for temperament and character subscales, which were comparable to US and other populations. The correlations between baseline and one month after administration of J-TCI-R were highly and statistically significant (r = 0.578–0.674 for scales and 0.366–0.582 for subscales) (n = 795). Factor analysis results using Eigenvalue greater than one rule indicated three out of four factors for temperament scales and one out of two factors for character subscales which were similar to findings from the other countries. When all of the subscales were subjected to factor analysis, four out of six factors were retained. To our knowledge, this is the first study analysing psychometric properties and factorial construct of the J-TCI-R.
Conclusions: The internal reliability coefficients and test–retest indicated a good stability of scores over time and the factorial structure was consistent with Cloninger’s model of personality. The reliability and validity of the Turkish version of the TCI is therefore supported.
