Predictors of Dropout, Outcome, and Relapse in Web-Based Guided Self-Help Cognitive Behavioral Therapy-Enhanced Among...

Area of Science:

• Psychiatry
• Psychology
• Behavioral Science

Background:

• Web-based guided self-help cognitive behavior therapy-enhanced (CBT-E) is a treatment for binge-eating disorder.
• Understanding predictors of dropout, treatment outcome, and relapse is crucial for optimizing this therapy.
• Data were gathered from a randomized controlled trial investigating CBT-E efficacy.

Purpose of the Study:

• To identify predictors of dropout from web-based guided self-help CBT-E for binge-eating disorder.
• To examine predictors of treatment outcome and relapse in patients undergoing this therapy.
• To analyze demographic and psychopathological factors influencing treatment adherence and effectiveness.

Main Methods:

• Logistic regression analyses were used to predict dropout and relapse.
• Multiple regression analysis assessed predictors of treatment outcome using residual change scores.
• Predictors included demographics, comorbid psychopathology, binge eating frequency, and eating disorder concerns, all measured at baseline.

Main Results:

• Dropout was associated with non-Dutch ethnicity, male sex, and lower educational attainment.
• Comorbid psychopathology predicted poorer treatment outcomes immediately post-treatment but not at follow-up.
• No significant predictors for relapse were identified in the study.

Conclusions:

• While comorbid psychopathology initially predicted less treatment benefit, patients showed improvement 12 weeks post-treatment.
• Non-Dutch ethnicity, male sex, and lower education levels are associated with higher dropout rates.
• Culturally sensitive and tailored interventions may be beneficial for reducing dropout in specific patient groups.
