Psychological Adjustment in Patients with Anorexia Nervosa and Binge Eating Disorder Following a 3-Week Inpatient Multidisciplinary Rehabilitation Program

TL;DR

A 3-week inpatient program improved emotional and psychological health in women with eating disorders, but longer interventions may be needed for behavioral and social issues.

Contribution

Demonstrates effectiveness of a multidisciplinary inpatient program for eating disorders and highlights areas needing extended treatment.

Findings

Significant improvements in emotional symptoms and psychological functioning were observed in both AN and BED patients.

BMI changes were significantly linked to emotional symptoms and overall well-being scores.

Limited changes were found in behavioral problems and social functioning, suggesting the need for more targeted interventions.

Abstract

Background: This study examined changes in psychological adjustment among patients with Anorexia Nervosa (AN) and Binge Eating Disorder (BED) following a 3-week inpatient multidisciplinary (disease-tailored) rehabilitation program. Methods: twenty consecutive Italian female adults with a diagnosis of AN (mean age ± SD: 25.9 ± 9.4 years; mean Body Mass Index: BMI: kg/m2: 15.8 ± 1.61) and fifteen consecutive Italian female adults with diagnosis of BED (mean age ± SD: 43.5 ± 15.3 years; mean Body Mass Index: BMI: kg/m2: 41.1 ± 7.82) were admitted to the study. Psychological functioning and well-being were assessed pre- and post-intervention using the Strengths and Difficulties Questionnaire and the Psychological General Well-Being Index. Results: Significant improvements in emotional symptoms [F(1, 31) = 21.1973, p < 0.001, ƞ2p = 0.406] and overall psychological functioning [F(1, 31) = 10.0062, p = 0.373, ƞ2p = 0.026] were observed in both groups, with the most pronounced changes in internalizing symptoms, such as anxiety and depression. Changes in BMI were significantly associated with emotional symptoms, vitality [F(1, 31) = 4.89, p = 0.035, ƞ2p = 0.136], and total well-being scores [F(1, 31) = 6.341, p = 0.017, ƞ2p = 0.170]. By contrast, no significant changes were observed in domains such as behavioral problems, hyperactivity/inattention, and peer relationships, probably indicating the need for more prolonged and targeted, domain-specific interventions. Conclusions: A 3-week inpatient multidisciplinary program was associated with improvements in internalizing symptoms and psychological well-being in women with AN and BED. Domains such as behavioral regulation and social functioning showed limited change, indicating the need for longer and targeted psychosocial components.
