Abstract

Lack of awareness of specific symptoms among persons with schizophrenia has not been adequately studied in the context of neuropsychological function. The purpose of this study is to investigate whether poor insight as measured by the Scale to Assess Unawarehess of Mental Disorder is empirically related to performance measures having a known association with executive functions in a group of individuals with chronic schizophrenia. The results showed that unawareness and misattribution of negative symptoms are significantly associated with deficits in some aspects of executive functioning even after a test of general intelligence had been partialed from the analyses. We conclude that unawarehess of negative symptoms is associated with executive functioning in individuals with chronic schizophrenia. Unawareness of other symptoms (i.e., positive symptoms) may reflect dysfunction in other types of neuropsychological processes, or it may reflect motivation to deceive oneself or others.
