title: Homogeneity and heterogeneity in schizophrenia.
abstract: This study provides a description of replicated findings of limited heterogeneity in DSM-III schizophrenics. Based now on a sample of 145 schizophrenics, in 1984 and 182 in 1991 it is suggested that the diagnosis is primarily given to chronic patients with poor prognoses, in turn restricting the utility of a process-reactive conceptualization of schizophrenia.
