The 20-Year Longitudinal Trajectories of Social Functioning in Individuals With Psychotic Disorders.
Social impairment is a long-recognized core feature of schizophrenia and is common in other psychotic disorders. Still, to date the long-term trajectories of social impairment in psychotic disorders have rarely been studied systematically. ⋯ The results highlight substantial variability of social outcomes within diagnoses-albeit overall worse social outcomes in schizophrenia spectrum disorders-and show remarkably stable long-term impairments in social functioning after illness onset across all diagnoses.
