Efficacy of a partial hospital programme for adults with eating disorders

Abstract

Partial hospital programmes (PHPs) have demonstrated efficacy in the treatment of eating disorders (EDs); however, few programmes have examined long-term outcomes across diagnoses, including subtypes of anorexia nervosa (AN). The present study examined the effectiveness of PHP for adult patients (n = 243) with AN-restricting subtype (n = 79), AN binge/purge subtype (n = 46), and bulimia nervosa (n = 118). These patients tended to have long-standing courses of illness (43%, illness duration >7 years) and high levels of psychiatric comorbidity (92.2%). Patients completed questionnaires at admission, discharge, and follow-up, M (SD) = 11.50 months (5.29). Through follow-up, all diagnoses demonstrated significant improvements in weight, ED psychopathology, and comorbid symptoms, with some exceptions for the AN binge/purge group. In exploratory analyses, 49% of patients met criteria for full or partial remission at discharge and 37% at follow-up. Results provide support for the effectiveness of PHP in improving ED outcomes in a severe sample through longer-term follow-up.
