Summary

Smartphones have the capability to monitor health-related behaviors (exercise, diet, etc.) and provide social support which has the potential to play a powerful role in health promotion. The objective of this study is to refine and pilot test the Social POD app for personalized health monitoring and interaction founded on a combination of social networks, recommender systems, motivational research, and health behavior theory. The aim of our proposed project is to conduct a 3-month pilot RCT among overweight and obese adults (N=150) comparing a theory-based podcast (TBP) plus self-monitoring using a commercially-available calorie and weight tracking app (current most popular diet self-monitoring method) versus TBP plus self-monitoring and social support/incentive points for participating with the Social POD app (TBP+Social POD).

Detailed description

Objectives and Significance. Smartphones have the capability to monitor health-related behaviors (exercise, diet, etc.) and provide social support which has the potential to play a powerful role in health promotion. The objective of this study is to refine and pilot test the Social POD app for personalized health monitoring and interaction founded on a combination of social networks, recommender systems, motivational research, and health behavior theory. Currently, we are recruiting for usability testing among obese and overweight (BMI \>25 kg/m2) adults (n=20) with our basic Social POD app. Our proposed project, which seeks to supplement our current line of research investigating mHealth interventions for overweight and obese adults, has two aims: Aim 1: Refine our intelligent social agent mobile app (Social POD) based on results from our usability testing and develop new components (i.e., incentive system) for use in a 3-month randomized controlled pilot trial (RCT). Aim 2: Conduct a 3-month pilot RCT among overweight and obese adults (N=150) comparing a theory-based podcast (TBP) plus self-monitoring using a commercially-available calorie and weight tracking app (current most popular diet self-monitoring method)9 versus TBP plus self-monitoring and social support/incentive points for participating with the Social POD app (TBP+Social POD). Once the final intervention is developed through Aim 1 including the incentive system, we will recruit 150 overweight adult Android smartphone owners (BMI 25-49.9 kg/m2; age 18-65; \>30% AA) to participate in a 3-month pilot of our enhanced intervention. Detecting differences in weight among the two groups is our primary research goal.
