Objectives：An increasing number of studies have observed poor clinical insight to be a reflection of neurocognitive dysfunction in schizophrenia. We examined whether cognitive insight as well as clinical insight were associated with a neurocognitive or psychological defensiveness problem.
Methods：Forty-five participants with schizophrenia underwent an assessment of insight, psychotic symptoms, neurocognitive function and psychological defensiveness：the Korean version of the Beck Cognitive Insight Scale (BCIS-K), the Korean version of the Scale to Assess Unawareness of Mental Disorder (SUMD-K), PANSS, scales L (Lie) and K (Correction) from the Minnesota Multiphasic Personality Inventory (MMPI) and neuropsychological battery. MMPI scales L and K were presumed to be indicative of psychological defensiveness and denial of problems. Additionally, 29 participants with schizophrenia underwent a same assessment except neuropsychological battery. Additional cases were tested TMT B instead of neuropsychological battery.
Results：Results showed that BCIS-K was significantly correlated with MMPI scales L and K (BCIS-K composite index and MMPI L and K：r=-.460, p<.01；r=-.335, p<.01；BCIS-K self-reflectiveness and MMPI L and K：r=-.498, p<.01；
r=-.521, p<.01；BCIS-K self-certainty and MMPI K：r=-.259, p<.05). No correlation between BCIS-K and TMT B was
found.
Conclusion：These results suggest that in contrast with previous investigations using SUMD, cognitive insight correlates with psychological defensiveness.
