Abstract

Schizophrenic outpatients with and without the deficit syndrome were administered Chapman's “psychosis proneness” scales. As hypothesized, deficit syndrome patients had higher scores on Social Anhedonia and Physical Anhedonia, but did not differ from nondeficit patients on Perceptual Aberration, Magical Ideation, or Impulsive Nonconformity. The differences between the two groups were not related to race, gender, age, socioeconomic status of family of origin, or drug treatment. These results support the validity of the deficit syndrome, and suggest that the Social Anhedonia and Physical Anhedonia scales may be useful in future studies of schizophrenia.
