This carefully controlled study demonstrated a highly significant absence of thought disorder in the borderline sample. Over-all, the borderline patients showed significantly fewer psychotic symptoms than the schizophrenic patients, and anxiety was higher in the schizophrenic group than in the borderline group. The authors compare their findings with those of Drinkers' earlier study and find agreement that both anger and intense dissociative experience may be useful symptoms in discriminating between the two groups. A surprising and important finding was that despite markedly different admitting symptoms, the two groups had similar prognostic and outcome characteristics. These results may support suggestions from genetic research and psychodynamic formulations that borderline patients are very similar to schizophrenic patients.
