Self-efficacy and psychosocial functioning in schizophrenia: a mediational analysis.

The construct of self-efficacy has been hypothesized to mediate the relationship between efforts at coping with psychiatric illness and functional outcome. This study examined whether self-efficacy mediated the relationships between psychosocial functioning and important predictors of functioning: premorbid functioning, negative symptoms, and cognitive functioning. Although self-efficacy was positively associated with psychosocial functioning, it did not mediate the relationships between functioning and the other established predictors. Rather, negative symptoms were the strongest predictor of functioning and mediated the relationship between self-efficacy and functioning. The findings suggest that negative symptoms, and not self-efficacy, are the most critical determinants of psychosocial functioning in schizophrenia, and that psychosocial treatment should focus on the amelioration of these symptoms.
