Cognitive deficits and psychiatric rehabilitation outcomes in schizophrenia

Many patients with schizophrenia are characterized by cognitive deficits that limit their ability to benefit from psychiatric rehabilitation interventions. While this suggests that cognitive rehabilitation is important, more needs to be known about which cognitive deficits interfere with which aspects of outcome and functioning before effective interventions are developed. We report data on cognitive predictors of three types of outcome: acquisition and performance of skills in a skills training group; aspects of daily ward functioning; and ability to be discharged from a state hospital. Our data indicate that poorer outcomes in each of these areas are associated with different, but somewhat overlapping, profiles of cognitive deficits. These data are relevant for designing both ward-based and individualized interventions. Integrating traditional psychiatric rehabilitation approaches with targeted cognitive interventions is necessary to maximize the impact of psychiatric rehabilitation services on individuals with chronic schizophrenia.
