A factor analysis of the Strauss and Carpenter revised outcome criteria scale: a validation of the French translation.
This article seeks to validate the French translation of the Strauss and Carpenter revised outcome criteria scale (SCOCS-R) through the study of its interrater reliability, its convergent validity, and its factor structure. Using a sample of 113 DSM-IV schizophrenic subjects, we assessed the interrater reliability of the SCOCS-R and its convergent validity with an already validated scale (Social and Occupational Functioning Assessment Scale). The factor structure of the SCOCS-R was assessed using a principal components analysis. Interrater reliability was excellent (ri > or = 0.88 for each of the individual items), and the convergent validity with the Social and Occupational Functioning Assessment Scale proved to be highly satisfactory (r = 0.89; p < .0001). Factor analyses yielded two factors corresponding to social functioning and professional functioning. These factors accounted for 78% of the variance of outcome. These results demonstrate the reliability and the validity of the French translation of the SCOCS-R. Moreover, the two dimensions yielded by our factor analysis add to the evidence of the multidimensional structure of outcome. This article supports the relevance of the SCOCS-R to assess the dimensions of outcome in schizophrenic subjects.
