Supplication: Team-Level Behavior Change Platform

Overview

Supplication (Supplement + Application) is a platform enhancing team-level behavior change using lifelog information sharing among team members based on competition and collaboration techniques.

Approach

• Six sharing models: Proposed and evaluated six lifelog sharing models combining "competition" and "collaboration" concepts (e.g., external competition, internal competition, collaboration, hybrid models)
• Team-based intervention: Leveraging social dynamics within teams to promote exercise behavior change
• Lifelog sharing: Sharing activity and health data (step counts, exercise records) among team members through the platform

Results

• A study with 64 participants over three weeks found that competition-based models were most effective for competitive teams such as sports teams
• The "external competition" model, where teams compete against each other, showed the strongest effect on exercise behavior change
• Received Best Paper Award at IEEE HealthCom 2014

Significance

Supplication demonstrates that team dynamics and social information sharing can be powerful drivers of health behavior change. The findings on competition vs. collaboration effectiveness provide design guidelines for team-based health promotion interventions.
