Abstract

There has been little research investigating how symptoms of schizophrenia and changes in symptomatology across the course of the illness relate to measures of quality of life in patients. We examined this issue in 45 patients assessed at hospital admission for illness exacerbation, at stabilization (prior to discharge) and at follow-up (5-9 months post- discharge). Symptom ratings at each time period consisted of the Brief Psychiatric Rating Scale (BPRS) and the Negative Symptom Assessment (NSA). The Heinrichs-Carpenter Quality of Life Scale (QLS) was administered upon admission to the hospital (assessing the 3 months prior to admission) and again at follow-up. Correlational analyses revealed relationships of both positive and negative symptoms with quality of life. These relationships are particularly strong at stabilization. Stepwise regression analyses revealed changes in the NSA motivation component to be most important in predicting quality of life for the patients at follow-up. BPRS psychosis and paranoia components are important predictors of quality of life at stabilization (but not during acute exacerbation). These results are important in terms of understanding the impact of changes in symptomatology on the quality of life for patients with schizophrenia as well as in targeting specific symptom clusters for treatment to maximize quality of life post-hospitalization.
