Reliability and validity of the Japanese version of the Temperament and Character Inventory

The Temperament and Character Inventory was translated into Japanese, and, to confirm the psychometric properties of the inventory, three samples were recruited from a nonpatient population. In nonpatient population A (N = 55 5), the full version (240 items) of the inventory with dichotomous measurin g, along with the General Health Questionnaire and the Social Desirability Scale, were distributed to the subjects. Factor analyses of the subscales s howed chat the factor structure of the inventory was consistent with Clonin ger's theory. Correlations of the scale scores with the General Health Ques tionnaire and the Social Desirability Scale scores were almost negligible, indicating that the scale is resistant to the current psychopathology and r esponse bias. In this and the other two university student samples (ns = 39 5 and 377), Cronbach coefficients alpha of the scale scores were substantia lly high except for the short version (125 items) of the inventory with dic hotomous measures. The Japanese version of the inventory appears to have in ternal reliability and content and construct validity in a Japanese populat ion.
