The purpose of the study was to investigate the relationship between the symptoms delusions and hallucinations mea-sured by the Positive and Negative Syndrome Scale and cognitive insight as assessed with the Beck Cognitive Insight Scale (BCIS) in patients with schizophrenia. The BCIS is based on 2 subscales, self-reflectiveness and self-certainty, measuring objectivity, reflectiveness and openness to feedback, and mental flexibility. Overall cog-nitive insight was defined as the difference between self-reflectiveness and self-certainty. This cross-sectional study of 143 patients showed that the occurrence of delusions is associated with low self-reflectiveness and high self-certainty, reflecting low cognitive insight. Hallucinations in the absence of delusions were associated with high self-reflectiveness and low self-certainty, possibly reflecting more open-mindedness and higher cognitive insight. The present findings suggest that delusions are associated with low cognitive insight, whereas solitary hallucinations may be associated with high cognitive insight
