Predictive validity of the Family Attitude Scale in people with psychosis
MetadataShow full item record
Expressed Emotion (EE) strongly predicts relapse in mental disorders, but there remains a need to develop and refine brief, self-report measures. This article describes two studies testing the validity of a self-report measure of criticism or burden, the Family Attitude Scale (FAS), in relatives of patients with psychosis. Study 1 had 54 families of patients with psychosis and a substance use disorder, while Study 2 had 61 families of patients at an early psychotic episode. In Study 1, a consensus FAS was obtained; in Study 2 separate parental scores were used. The FAS was positively associated with EE, and with relationship negativity. Associations with negative caregiving experiences or stress were restricted to maternal or consensual FAS ratings. FAS scores predicted relapse in both studies, although prediction at the optimal cutoff (= 60) only reached statistical significance in Study 2, and time to relapse was only predicted by the FAS in Study 1. Prediction of relapse from the CFI was stronger, and the FAS did not add to that prediction. Results supported the utility of the FAS, but confirmed the pre-eminence of the CFI as a household-related predictor of relapse. 頲007 Elsevier Ireland Ltd. All rights reserved.
