Self-Guided Psychological Interventions for the Treatment and Prevention of Eating Disorders: A Meta-Analysis of Randomized Controlled Trials
Background
Self-guided interventions may broaden the dissemination of evidence-based prevention and treatment protocols for eating disorders. We conducted a meta-analysis comparing self-guided prevention and treatment approaches for eating disorders to (1) control groups and (2) professionally guided self-help programs.
Methods
Forty-six trials were included. Interventions ranged from web, to app, to CD-ROM to book-based programs. Random effects meta-analyses were conducted on numerous symptom and risk outcomes.
Results
Only four trials recruited an unselected sample, with self-guided programs reducing shape/weight concerns over control groups (g = 0.18). Among high risk/symptomatic samples (k = 25), self-guided interventions reduced several behavioural and cognitive symptoms (gs = 0.31–0.50) over control groups, with effects being robust when adjusting for higher risk of bias and small sample trials. Among clinical samples (k = 17), evidence for the effectiveness of self-guided interventions over control groups on symptom measures was only found for binge-eating disorder, as too few studies sampled other diagnostic subtypes. Among 10 trials that compared guided to unguided self-help, we observed a significant effect in symptom reduction in favour of guided self-help (g = −0.26). Dropout did not differ between guided and unguided self-help (OR = 0.97).
Conclusion
Self-guided interventions may be an effective, low intensity intervention format for high risk individuals or for binge-eating disorder presentations.
期刊介绍：
European Eating Disorders Review publishes authoritative and accessible articles, from all over the world, which review or report original research that has implications for the treatment and care of people with eating disorders, and articles which report innovations and experience in the clinical management of eating disorders. The journal focuses on implications for best practice in diagnosis and treatment. The journal also provides a forum for discussion of the causes and prevention of eating disorders, and related health policy. The aims of the journal are to offer a channel of communication between researchers, practitioners, administrators and policymakers who need to report and understand developments in the field of eating disorders.
