Abstract

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.

自我引导心理干预治疗和预防饮食失调：随机对照试验的荟萃分析。

背景：自我指导干预可能会扩大以证据为基础的饮食失调预防和治疗方案的传播。我们进行了一项荟萃分析，将自我指导的饮食失调预防和治疗方法与(1)对照组和(2)专业指导的自助计划进行比较。方法：纳入46项试验。干预措施包括网络、应用程序、CD-ROM和基于书籍的程序。随机效应荟萃分析进行了许多症状和危险结果。结果：只有四项试验招募了未选择的样本，与对照组相比，自我指导的程序减少了对形状/体重的担忧（g = 0.18）。在高风险/有症状的样本（k = 25）中，与对照组相比，自我引导干预减少了几种行为和认知症状（gs = 0.31-0.50），在调整了较高的偏倚风险和小样本试验后，效果仍然很明显。在临床样本（k = 17）中，自我指导干预在症状测量上优于对照组的证据仅在暴饮暴食症中发现，因为对其他诊断亚型进行采样的研究太少。在比较有指导和无指导自助的10项试验中，我们观察到有指导自助在减轻症状方面有显著效果（g = -0.26）。在有指导的自助和无指导的自助之间，辍学率没有差异（OR = 0.97）。结论：自我指导干预可能是一种有效的、低强度的干预形式，适用于高危人群或暴食症患者。
