Symptomatological and cognitive predictors of insight in chronic schizophrenia.
Studies of schizophrenia show lack of agreement about the relationship of symptomatological and cognitive factors to insight. In this study, positive and negative symptomatology and cognitive function were assessed by the Positive and Negative Syndrome Scale (PANSS), the Wisconsin Card Sorting Test (WCST), and the Wechsler Adult Intelligence Scale Revised (WAIS-R) in male chronic schizophrenic patients in relation to level of insight measured with the Japanese version of the Schedule for the Assessment of Insight (SAI-J). Negative symptoms were significantly and negatively associated with overall insight, particularly with treatment compliance and recognition of mental illness. The present findings suggest that aspects of insight such as treatment compliance and recognition of mental illness are negatively associated with negative symptoms.
