title: The impact of insight on functioning in patients with schizophrenia or schizoaffective disorder receiving risperidone long-acting injectable.
abstract: This post hoc analysis explored the role of insight as a mediator of functioning in a 52-week, double-blind, international trial of 323 patients with schizophrenia or schizoaffective disorder receiving risperidone long-acting injectable. Measures included the Positive and Negative Syndrome Scale (PANSS) insight item, PANSS factors, Clinical Global Impressions-Severity (CGI-S), Strauss-Carpenter Levels of Functioning (LOF), Personal and Social Performance (PSP) scale, and a cognitive test battery. Correlation/regression analyses examined associations between demographic and clinical characteristics, including insight, and functional measures. Insight scores correlated significantly with CGI-S, PANSS subscales, PSP, LOF, and several cognitive measures. Regression models demonstrated that changes in insight, changes in negative symptoms, and study duration were significantly associated with PSP and LOF total change scores. Findings identified important variables to consider for intervention to improve functioning in schizophrenia.
