Cognitive insight and acute psychosis in schizophrenia.
Cognitive insight is a new concept. There are very few data regarding the relationship between cognitive insight and positive symptoms. The goal of the present study was to investigate the impact of acute psychosis (delusions and hallucinations) on overconfidence in judgments and self-reflectiveness of patients with schizophrenia. The Beck Cognitive Insight Scale was used to compare the cognitive insight of schizophrenia patients with (n = 93) and without (n = 45) current psychotic symptoms. Clinical symptoms and clinical insight of the patients were also assessed. The present findings suggest that both overconfidence in judgments and impaired self-reflectiveness are associated with acute psychosis. Only diminished self-reflectiveness seem to be improved following hospitalization. Although overconfidence of schizophrenia patients in their judgments was more severe in schizophrenia patients with psychotic symptoms, self-certainty of schizophrenia patients may be a relatively persistent characteristic that is also present after recovery of psychosis. Studies with larger samples involving follow up for longer periods will be valuable to understand the nature of the relationship between cognitive insight and clinical symptoms of schizophrenia.
