(2004) and the Beck Cognitive Insight Scale. Relative to both healthy controls and nondelusional patients, delusional participants were specifically impaired on metacognitive measures of free choice improvement and global monitoring. This was correlated with high self-certainty on the BCIS relative to nondelusional patients. Our results suggest that metacognitive impairments play an important role in the ...
