Patients who meet DSM‐III criteria for schizophrenia were compared with those who meet DSM‐II, but not DSM‐III, criteria. Comparisons included measures of positive symptoms, negative symptoms, and social competence both before extended hospitalization and during a 7‐year follow‐up. The measure of positive symptoms was the only variable that differed significantly between groups at initial assessment. Positive symptoms were more stable and predictive for DSM‐III schizophrenics than for DSM‐II schizophrenics. The measure of negative symptoms was the most stable and predictive variable for the DSM‐II schizophrenics. Increased homogeneity for the DSM‐III schizophrenics was not found for most measures.
