Adjusted average means for health-related quality of life between initial hospitalization and 1 year later, for levels of co-occurring psychiatric disorders. Means are averaged over 3 assessments (initial hospitalization, and 3 and 12 months later) and are adjusted for age, race, marital status, medical diagnosis, and severity of medical illness. All contrasts are strongly statistically significant (P < .001) except for the physical functioning index (P = .03).
