Despite their widespread use and extensive technical features, little is known about how to use online social networking sites to increase physical activity. This study aims to examine Facebook engagement among participants in the online social networking arm of a randomized controlled physical activity promotion trial (n = 67). Facebook communications were double coded and analyzed using ATLAS.ti. Regression procedures were used to determine predictors of Facebook use and associations between types of use and changes in perceived social support and physical activity. Changes in perceived social support and physical activity were more strongly associated with participants' individual Facebook use than use of the Facebook intervention group. The way social media sites are used in intervention design could have an impact on their effects. Including existing friends in interventions and using applications that incorporate intervention activities into a more naturalistic use of Facebook may improve the efficacy of future interventions.
尽管在线社交网站被广泛使用且具备丰富的技术特性，但对于如何利用这些网站来增加身体活动，我们却知之甚少。本研究旨在调查一项随机对照身体活动促进试验的在线社交网络组参与者（n = 67）在脸书上的参与情况。脸书通信进行了双重编码，并使用ATLAS.ti进行分析。采用回归程序来确定脸书使用的预测因素以及使用类型与感知到的社会支持和身体活动变化之间的关联。与脸书干预组的使用情况相比，感知到的社会支持和身体活动的变化与参与者个人使用脸书的关联更为紧密。社交媒体网站在干预设计中的使用方式可能会对其效果产生影响。在干预中纳入现有朋友，并使用将干预活动融入更自然的脸书使用方式的应用程序，可能会提高未来干预措施的效果。
