Testing the Efficacy of an Online Social Network Intervention to Increase Social Support for Physical Activity (INSHAPE)

April 15, 2016 updated by: University of North Carolina, Chapel Hill

Using Facebook to Increase Social Support for Physical Activity: The INSHAPE Study

This study was designed to determine whether participation in an online social network intervention increases perceived social support for physical activity versus a minimal education control group by conducting a randomized controlled trial with 140 female undergraduate students. The investigators hypothesize that participants in the physical activity centered online social network intervention group will have greater increases in perceived social support for physical activity compared to minimal web based physical activity education controls.
