Applying a web-based self-help intervention for bulimia nervosa in routine care: Study protocol for a randomized...

Area of Science:

• Psychiatry and Behavioral Science
• Digital Health Interventions
• Eating Disorder Treatment

Background:

• Bulimia nervosa (BN) is characterized by binge eating and compensatory behaviors, leading to significant health impairments.
• Many individuals with BN face barriers to accessing effective treatments, increasing the risk of chronic conditions.
• Web-based interventions offer a potential solution to improve treatment accessibility for BN.

Purpose of the Study:

• To investigate the effectiveness of a 12-week web-based self-help intervention for individuals diagnosed with bulimia nervosa.
• To assess the impact of the intervention on binge eating episodes and compensatory behaviors.
• To evaluate secondary outcomes including eating pathology, functional impairment, and psychological well-being.

Main Methods:

• A two-armed randomized controlled trial involving 152 individuals with BN.
• Participants were randomly assigned to either a web-based intervention group or a waitlist control group.
• Primary outcomes (binge eating, compensatory behaviors) and secondary outcomes were assessed at baseline, 6, and 12 weeks post-treatment.

Main Results:

• This section is not available in the provided abstract.
• Further assessments will be scheduled 6 (mid-treatment) and 12 (post-treatment) weeks after baseline.
• Changes in the number of binge eating episodes and compensatory behaviors will be examined as primary outcomes.

Conclusions:

• Integrating web-based interventions into routine care may help bridge the treatment gap for BN.
• This study aims to validate a web-based intervention for BN within standard clinical settings.
• Web-based self-help interventions show potential for increasing access to evidence-based care for bulimia nervosa.
