Abstract
BACKGROUND AND OBJECTIVES: The aim of this study was to assess the impact of meta-cognitive training (MCT) on cognitive biases, symptoms, clinical insight, and general functioning among low-level functioning persons diagnosed with chronic schizophrenia who were attending adaily Community Social Support Group Program; we compared the treatment-as-usual (TAU) condition with the MCT + TAU condition. METHODS:Forty-four patients diagnosed with chronic schizophrenia were allocated to either the MCT + treatment-as-usual condition or the treatment-as-usual (TAU) condition. Delusion and hallucination severity, cognitive biases, clinical insight, and global functioning were assessed pre- and post-treatment (clinical trial NCT02187692). RESULTS: No significant changes were found in symptom severity as measured with the PSYRATS. Conversely, a medium to large effect size was observed for delusional ideation changes when assessed by the self-report measure (Paranoia Checklist). MCT was found to ameliorate cognitive biases as measured by the self-report scale at large effect size, however, no changes in jumping to conclusions (the Fish Task) and theory of mind deficits ("Reading the Mind in the Eyes" Test) were found in the behavioral tasks. MCT increased insight at large effect size. No changes in global functioning were found between the two conditions. LIMITATIONS: Low intensity intervention. No follow-up assessment was provided. Only PSYRATS was assessed blind to patient allocation. CONCLUSIONS:MCT has a beneficial effect on low-functioning chronic schizophrenic patients in ameliorating cognitive biases and increasing clinical insight.
