Abstract :

This study aimed to investigate the psychometric properties (validity, reliability and factorial structure) of the Persian version of the Washington University Sentences Completion Test (WUSCT; Hy & Loevinger 1996) for evaluating ego development. Two hundred and eighty nine undergraduate students (143 females, 146 males) were selected from different disciplines of Tehran University using convenience sampling. The guilt subscale of the Personal Feeling Questionnaire (Harder & Zalma, 1990) and the Chronic Self-Destructiveness Scale (Kelley, et al., 1985) were used for studying divergent validity. The results indicated that the WUSCT had appropriate internal consistency (ranged from 0/118 to 0/326). The Cronbach α and 2-weeks test-retest reliability were .781 and .876, respectively. The negative correlation of the WUSCT with self-destructiveness demonstrated the divergent validity of the WUSCT. The WUSCT could discriminate the group with high ego development from the group with low guilt and self-destructiveness which indicated the discriminant validity of the WUSCT. The factorial analyses indicated that the WUSCT was unidimensional. The findings suggest that the Persian version of the WUSCT is a valid and reliable tool for assessing ego development.
