Studying schizophrenia outside the psychiatric setting.

Two groups of college students were identified using the MMPI as a screening device: those with normal profiles and those with schizophrenic profiles. All those with previous psychiatric treatment were eliminated. A third group of hospitalized schizophrenics was matched to the first two along lines of age, sex and socioeconomic status. The three groups were then studied via a semistructured interview and compared for the clinical features of hospitalized schizophrenics and for objective enironmental stresses. As predicted, a group of well-functioning, untreated schizophrenics was delineated. The usefulness of the MMPI as a screening device is clarified, and the question of the true prevalence of schizophrenia is discussed. Contrary to prediction, the well-functioning schizophrenics were similar to the hospitalized schizophrenics, not to the normal controls, with regard to objective environmental stresses. The possible meaning of this is discussed considering the concept of subjective environmental stresses.
