Anhedonia and schizophrenia
M Cook and F Simukonda
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.
