Psychoeducation for Parents of Adolescents With Anorexia Nervosa as a Supportive Treatment Approach

Обзор

This randomized controlled trial will evaluate the effectiveness of a structured four-week psychoeducation program for parents of adolescents diagnosed with anorexia nervosa (AN). The program aims to improve parental coping and improve adolescent treatment outcomes. Seventy adolescents with AN (ages 11-19) and their parents will be recruited at the University Medical Centre Ljubljana, Slovenia. Families will be randomly assigned to either an intervention group, receiving immediate psychoeducation, or a waitlist control group, receiving the program after one month. The psychoeducation program consists of four weekly 90-minute sessions covering eating disorder characteristics, maintaining factors, strategies for normal eating, and approaches for supporting change. Primary outcomes include change in adolescent body mass index (BMI) from baseline to post-intervention and three-month follow-up. Secondary outcomes include adolescent symptoms of eating disorders, anxiety, and depression, as well as parental anxiety, depression, stress, social support, and self-efficacy. The study will test whether early, structured parental involvement through psychoeducation improves both adolescent clinical outcomes and parental coping.

Подробное описание

Anorexia nervosa (AN) is a severe psychiatric disorder with high morbidity and mortality, typically emerging during adolescence. Effective treatment requires family involvement, yet parents frequently experience high levels of stress, anxiety, guilt, and isolation while supporting their child through treatment. Psychoeducation for parents may reduce parental distress and simultaneously enhance adolescent treatment outcomes, but rigorous randomized trials are limited.

This randomized controlled trial will evaluate a structured four-week psychoeducation program for parents of adolescents diagnosed with anorexia nervosa (AN). The intervention is designed to complement treatment as usual and is based on principles from enhanced cognitive-behavioral therapy for eating disorders (CBT-E) and existing psychoeducational protocols. The program aims to improve parental coping skills, reduce parental psychological distress, and improve adolescent treatment outcomes.

Families will be recruited from the Child Psychiatry Department at the University Medical Centre Ljubljana, Slovenia. After providing informed consent, families will be randomized into either:

Intervention group - parents receive immediate participation in the psychoeducation program while their adolescents continue treatment as usual, or

Waitlist control group - parents continue treatment as usual and receive the program after one month.

Each psychoeducation group will include parents of up to seven adolescents and will meet weekly for four sessions, each lasting 90 minutes. Session structure includes: review of previous homework, introduction of new material, core psychoeducational content, and assignment of new tasks. Topics progress from understanding eating disorder characteristics and myths, to identifying maintaining factors, establishing normal eating patterns, and promoting sustainable behavioral and emotional change.

Both adolescents and parents will complete assessments at defined time points. Adolescents will be evaluated for changes in body mass index (BMI) and self-reported psychological symptoms, while parents will be assessed for anxiety, depression, stress, perceived social support, and self-efficacy. The intervention group will be assessed at baseline, immediately post-intervention, and three months after the program, while the waitlist control group will complete assessments at baseline and one month later, prior to receiving the intervention.

The primary outcome is change in adolescent BMI from baseline to post-intervention. Secondary outcomes include changes in adolescent eating disorder symptoms, anxiety, and depression, as well as parental psychological well-being and coping. The study will use a waitlist-controlled design to isolate the effects of the psychoeducation program and will monitor whether improvements are sustained at three-month follow-up.

The trial is expected to provide evidence on the role of structured parental psychoeducation as an adjunct to standard treatment for adolescent AN and to offer a scalable model for integrating family-focused interventions into child and adolescent mental health services.
