Digital design of eating disorder treatments: A systematic review and meta-analysis

The current review and meta-analysis aimed to determine which components of web-based interventions are associated with higher attrition and improved therapeutic outcome in eating disorder treatment. A systematic of electronic databases were searched for published studies of web-based interventions for eating disorders and a meta-analysis of the final included studies was conducted. Each intervention was coded across four dimensions including multimedia channels, automated feedback, and technological device. A final 23 studies were included in the review. The results of meta-regressions indicated that higher scores on the multimedia subscale were associated with greater eating disorder symptom improvement in treatment groups. Conversely, higher scores on the feedback subscale were associated with greater reductions in eating disorder psychopathology in the control group. Other intervention components were not associated with treatment outcome or dropout. <br>

本项综述与元分析旨在明确进食障碍（eating disorder）治疗中，基于网络的干预措施（web-based interventions）的哪些组分与更高的脱落率以及更优的治疗结局相关。研究人员对电子数据库开展系统性检索，以获取已发表的进食障碍基于网络的干预措施相关研究，并对最终纳入的研究实施元分析。每项干预措施均从四个维度进行编码，涵盖多媒体渠道、自动化反馈以及技术设备。本次综述最终纳入23项研究。元回归分析结果显示，干预组中，多媒体子量表得分越高，进食障碍症状改善程度越显著；与之相反，对照组中，反馈子量表得分越高，进食障碍精神病理症状的减轻幅度越大。其余干预组分与治疗结局或脱落率均无显著关联。
