The characterization of social anhedonia and its correlates in schizophrenia and schizoaffective patients.

Although social hedonic capacity is often assessed in clinical settings, its operational definitions have not been evaluated for concurrent validity. One hundred and twenty-five patients with schizophrenia and schizoaffective disorder were classified according to their self-reported social hedonic functioning into three groups on the basis of their total scores on the Anticipatory and Consummatory Interpersonal Pleasure Scale (ACIPS). Participants were assessed before discharge using questionnaires and psychiatric rating scales. Using an empirically based cutoff score, we identified three groups: an intact social hedonic group (WNL), a socially anhedonic group (SA), and a socially hypohedonic group (i.e., those with scores intermediate between normal functioning and aberrantly low functioning, H). The SA patients were significantly different from the two other groups (WNL and H) by their higher severity of psychopathology, lower levels of self-efficacy, and less self-esteem. The SA patients also reported less perceived social support, poorer quality of life, and less subjective recovery. Our findings indicate that social anhedonia is a meaningful target for intervention. Further implications of our findings are discussed.
