Anhedonia and schizophrenia

Abstract

Data from Chapman's anhedonia and perceptual aberration scales are presented for groups of schizophrenics and hospital staff control subjects. Differences between the two groups are found for both anhedonia scales and for the perceptual aberration scale, but the difference for physical anhedonia is only marginally significant. The anhedonia scales do not differentiate between the two groups sufficiently well to be useful diagnostically.
