Predictors of remediation success on a trained memory task.

Full Abstract

Cognitive remediation has led to improvements for some but not all individuals with schizophrenia. The goal of the current investigation was to determine which variables predicted response to cognitive remediation training. In a sample of 58 patients with DSM-IV schizophrenia or schizoaffective disorder, normalization of performance on a trained memory task was selected as the criterion for successful remediation. The contribution of demographic, symptom, treatment process, and cognitive variables in predicting successful remediation was examined using a series of logistic regressions. A final regression evaluated the combined contribution of these variables. From among patients who were impaired before training, 43% reached normal levels of performance. Measures of attention, immediate verbal memory, hostility, and latency between last training and assessment were retained in the final step of the regression, resulting in 83% classification accuracy. Findings suggest that in addition to cognitive factors, motivational and training variables also significantly affect remediation outcomes.
