Earlier researchers have suggested that the ability of process‐reactive measures to predict future adjustment may result from their relationships to the anhedonia dimension. In the present study the abilities of process‐reactive and anhedonia measures, independent of one another, to predict rehospitalization data were compared. After anhedonia scores had been partialed out, schizophrenics' process‐reactive scores were correlated modestly with length of the patients' next hospitalization and reclassification as nonschizophrenic. No such significant correlations appeared between anhedonia and adjustment measures after process‐reactive scores had been partialed out. Among nonschizophrenics, a sizeable correlation between anhedonia and the probability of later diagnosis of schizophrenia appeared, which suggests that anhedonia may be a useful prodromal marker for schizophrenia.
