Protocol Summary
This study investigates how positive and negative social network processes influence weight loss among individuals participating in a 24-week, evidence-based lifestyle intervention modeled after the Diabetes Prevention Program. The protocol provides an example of utilizing the narrative interface as a visualization tool for a participant's social network, displaying alter edges, group and individual alter attribute variables, and allowing for dynamic repositioning of nodes to elicit qualitative data about the network.
