This study has attempted to investigate the cognitive insight in schizophrenic patients. Specifically this study examined the relationships between cognitive and clinical insight, and between cognitive/clinical insight and neuropsychological functions in schizophrenic patients. For the measurement of cognitive and clinical insight, Beck Cognitive Insight Scale (BCIS) and Scale to Assess Unawareness of Mental Disorder (SUMD) were administered, respectively. The frontal functions were evaluated by Wisconsin Card Sorting test (WCST), Controlled Oral Word Association Test (COWA), Trail Making Test (TMT) and d2 test. The schizophrenic symptoms were measured by The Positive and Negative Syndrome Scale (PANSS), and K-WAIS was administered to measure IQ. Fifty schizophrenic patients participated in this study. The results showed a significant correlation between BCIS and SUMD. There were associations between self-reflectiveness subscale of BCIS and TMT, part B response time, between self-confidence subscale of BCIS and COWA (letter)/concentration index of d2 test/ estimated IQ, and between SUMD and TMT, part A response time. In addition, both BCIS and SUMD were significantly associated with general pathology of PANSS. All of these results indicate that BCIS is a reliable and valid tool for the measurement of insight of schizophrenic patients, and although cognitive and clinical insight share common factors but seem to be related to the different cognitive functions.
