The reliability and construct validity of scores on the Japanese version of an academic self-concept scale for a sample of college students

Abstract

This study investigated the internal consistency, reliability, and construct validity of scores on the Japanese version of the Dimensions of Self-Concept (DOSC) academic self-concept scale for a sample of 177 students at a small Japanese private college. Confirmatory factor analyses showed promising support for the construct validity of scores on the six factor subscales (Level of Aspiration, Anxiety, Academic Interest and Satisfaction, Leadership and Initiative, Identification versus Alienation, and Stress), representing the six hypothesized constructs of academic self-concept. Internal consistency reliability of scores on the six subscales ranged from 0.82 to 0.87.
