Measurement of improvement in "mental illness."

Abstract
Data is presented on the relationship between behavioral adjustment and psychopathology as related to each other and to the level of posthospital adjustment. The Ss were functional psychotic patients under 60 years of age, without major physical illness, hospitalized no longer than 90 days during a specified period. The lack of significant psychopathology assessment and "external" criteria seems to raise serious doubts as to the usefulness of psychopathology as a socially meaning criterion of improvement.
