Beck and collaborators have proposed a distinction between clinical insight and cognitive insight and have developed a tool for the assessment of the latter, namely the Beck Cognitive Insight Scale (BCIS). The present study explored in 51 patients with a first episode of psychosis the neurocognitive correlates of cognitive insight as assessed with the BCIS. Global measures for seven domains of cognition including verbal learning and memory, visual learning and memory, working memory, speed of processing, reasoning and problem solving, attention, and social cognition were examined. Secondly, we examined whether two clinical insight measures, the Scale to assess Unawareness of Mental Disorder (SUMD) and the insight item from the Positive and Negative Symptoms Scale (PANSS), could produce similar or different patterns of association with neurocognitive functions as those identified with the BCIS. Correlational analyses revealed significant associations between the BCIS Composite Index and the verbal learning and memory. No significant associations were observed between any of the neurocognitive domains and the PANSS or SUMD clinical insight measures, despite high inter-correlations among the three insight measures. These results suggest that cognitive insight, but not clinical insight, may rely on memory processes whereby current experiences are appraised based on previous ones.
