Taiminen, Heini. "How do online communities matter? Comparison between active and non-active participants in an online behavioral weight loss program." Computers in Human Behavior 63 (2016): 787-795.

The paper examines the effectiveness of various social media platforms in promoting health behavior changes, particularly in an online behavioral weight loss program. It finds that active participation in online community platforms leads to a more positive service experience, better adherence to program instructions, and a stronger perception of social support and goal achievement, though not significantly affecting weight loss outcomes. Notably, participants in Facebook-based communities reported receiving more emotional support compared to those in discussion forum-based communities, highlighting the impact of platform choice on user experience. The study suggests strategies for service providers to enhance user engagement and support in online health programs.
