The authors describe the characteristics of 100 young adults with schizophrenia or schizophrenia-related disorders who are being treated in the community, patients who are at high risk for serious, long-term impairment but have not necessarily developed such impairment yet. In contrast to subjects in some other studies of young adult chronic patients, the patients show great variability in previous levels of functioning, such as employment history, ability to live independently, and drug use. The authors hypothesize that highly individualized assessment and comprehensive treatment provided early in the course of illness can prevent or limit chronic functional disability for many patients; they provide recommendations for such treatment.
