The use of social networking sites to deliver behavioral interventions is becoming more prevalent. The purpose of this review was to systematically evaluate the published research to determine the effectiveness of Facebook-delivered interventions for promoting physical activity behavior change.
A search of interventions delivered via Facebook (as the primary delivery method or part of a multifaceted intervention) in which physical activity was the primary or secondary outcome resulted in 8 studies for review.
Overall, 87.5% of the Facebook interventions reported some type of significant physical activity behavior change (ie, interactions, main effects for time, differences between conditions); however, only 2 of these interventions found this change to be significantly better for the treatment group than the control group.
Future researchers are encouraged to test the effectiveness of Facebook-delivered physical activity interventions with additional control groups that receive no aspects of the intervention within experimental study designs, more diverse samples, theory-based content with assessment of mediators of behavior change, direct observations of physical activity, and long-term follow-ups. Although based on a small sample of studies, Facebook appears to be a promising delivery method for physical activity interventions.
利用社交网站开展行为干预正变得越来越普遍。本综述的目的是系统评估已发表的研究，以确定通过脸书开展的干预措施对促进身体活动行为改变的有效性。
检索以脸书为主要传播方式或作为多方面干预措施一部分的干预措施，其中身体活动为主要或次要结果，共检索到8项研究进行综述。
总体而言，87.5%的脸书干预措施报告了某种类型的显著身体活动行为改变（即互动、时间主效应、不同条件之间的差异）；然而，这些干预措施中只有2项发现治疗组的这种改变明显优于对照组。
鼓励未来的研究人员在实验研究设计中，通过额外的未接受任何干预措施的对照组、更多样化的样本、基于理论的内容并评估行为改变的中介因素、直接观察身体活动以及长期随访，来测试通过脸书开展的身体活动干预措施的有效性。尽管基于少量研究样本，但脸书似乎是一种有前景的身体活动干预传播方式。
