Inpatient treatment for eating disorders: outcome at discharge and 3-month follow-up.

There have been few studies of inpatient treatment for eating disorders. Existing studies have mostly examined small samples of either anorexic or bulimic patients. The current study evaluated large samples of anorexic and bulimic inpatients at intake, discharge, and a 3-month follow-up. At discharge, patients in both groups showed substantial and statistically significant improvements on self-report measures of depression and eating disorder symptomatology. Treatment gains were largely maintained at follow-up. Correlational analyses found consistent inverse relationships between degree of change experienced during and after hospitalization. More favorable outcome during treatment was associated with less favorable outcome after treatment. Implications of these findings for the assessment and treatment of eating disorders are discussed.
