Cognitive insight in schizophrenia: the missing link between insight and neurocognitive complaint?

The aim of this study was to explore the associations between cognitive insight, clinical insight, and neurocognitive complaint in a sample of 54 outpatients with schizophrenia spectrum disorders. Cognitive insight assessed using the Beck Cognitive Insight Scale (BCIS) was not associated with clinical insight assessed using the Scale to Assess Unawareness of Mental Disorder. Associations were found between the BCIS scores and the neurocognitive complaints assessed using the Subjective Scale to Investigate Cognition in Schizophrenia. A high level of neurocognitive complaints was positively associated with self-reflectiveness and negatively associated with self-certainty about beliefs and judgments. These results provide further support for the construct validity of the BCIS. The data also suggest that cognitive insight and neurocognitive complaint are close constructs that should be differentiated from awareness of having a mental illness.
