The Relative Stability of Positive and Negative Features in Chronic Schizophrenia

Abstract

The mental states of 92 inpatients with chronic schizophrenia were assessed on two occasions 4 years apart. The relationship between the two ratings was examined in the 84 patients who were either consistently on or consistently off neuroleptics. Negative features were more stable than positive, but were not irreversible. Every feature examined was shown to resolve in some cases.
