| Abstract: | The frequency and associations of multiple diagnoses were examined in 205 psychiatric inpatients. The Washington University research criteria assessed past and current episodes of illness. Over half the sample received more than one diagnosis. Correlations and factor analysis suggested that alcoholism, antisocial personality, and drug dependence form one group; primary depression, primary mania, and secondary affective disorder form another. Schizophrenia was not associated with any of the other six diagnoses. The findings suggest that multiple diagnoses occur frequently, and the presence of one diagnosis should encourage the diagnostician to search for others.
