Studies investigating the factor structure of the BCIS have indicated a two-factor model in the psychotic population. The factor structure of the BCIS however has not received much consideration in the nonpsychiatric population. The present study examined the factor structure and validity of the BCIS and compared its scores between nonpsychiatric individuals and outpatients with psychosis. Method The Taiwanese version of the BCIS was administered to 507 nonpsychiatric individuals and 118 outpatients with schizophrenia. The psychometric properties of the BCIS were examined through the following analyses exploratory and confirmatory factor analyses reliability correlation analyses and discriminative validity. Results The BCIS showed adequate internal consistency and stability over time. Exploratory and confirmatory factor analyses on the 15-item measure indicated a two-factor solution that supported the two dimensions of the Taiwanese BCIS which was also observed with the original BCIS. Following the construct validation we obtained a composite index self-reflectiveness minus self-certainty of the Taiwanese BCIS that reflected cognitive insight. Consistent with previous studies our results indicated that psychosis is associated with low self-reflectiveness and high self-certainty which possibly reflect lower cognitive insight. Our results also showed that better cognitive insight is related to worse depression in .
