A note on the pathology of anhedonia.
Tested the hypotheses that anhedonia afflicts only a minority of schizophrenics and is bimodally distributed among them by comparing the Anhedonia scale distributions of schizophrenic and psychiatric control samples (N = 90). Only 45% of the schizophrenics produced scores higher than those characteristic of the controls. While the schizophrenics' distribution appeared to be bimodal, its irregularity precluded a definitive assessment of the bimodality hypothesis. The correlation between age and Anehodina was positive for anhedonics but not for non-anhedonic schizpohrenics or controls; these findings suggest that anhedonia is a mildly progressive disorder among those schizophrenics who experience it.
