title: Psychiatric morbidity in the relatives of patients with DSM-III schizophreniform disorder: comparisons with the relatives of schizophrenic and bipolar disorder patients.
abstract: Risks for psychiatric disorders (RDC) among first degree relatives of DSM-III schizophreniform, bipolar, and schizophrenic probands obtained from an epidemiologic sample using family history methods were examined. The relatives of the schizophreniform probands differed from the relatives of the schizophrenic and bipolar probands. The relatives of schizophreniform probands had significantly higher rates of affective illnesses (with the exception of bipolar illness) than the relatives of schizophrenic probands, and they had a significantly higher rate of psychotic affective disorders than the relatives of the bipolar probands.
