  • Title: Delusions are associated with low self-reflectiveness in first-episode psychosis.
    Author: Buchy L, Malla A, Joober R, Lepage M.
    Journal: Schizophr Res; 2009 Jul; 112(1-3):187-91. PubMed ID: 19372032.
    Abstract:
    Previous work on chronic psychosis patients has suggested that low self-reflectiveness and overconfidence in judgments may be associated with delusions. In the present study we evaluated whether this extends to a first-episode psychosis sample. Thirteen actively delusional and 53 non-delusional participants with a first-episode psychosis completed the Beck Cognitive Insight Scale. Relative to non-delusional participants, delusional participants endorsed greater self-reflectiveness, though their confidence in their judgments was the same as non-delusional participants. These results suggest that the capacity to self-reflect and refrain from overconfidence may interact with delusions differentially across multiple phases of psychosis. The cognitive system involved in self-reflectiveness may be important for delusional thinking during a first-episode psychosis.
