Summary

This project is a partnership between Emmi Solutions, a private company that delivers health promotion messages to employees of client organizations, and the University of Michigan and affiliated academic investigators. In particular, Emmi sends out pre-recorded and interactive telephone calls on behalf of their healthcare clients to promote influenza vaccination each Fall. The collaboration will design various scripts (based on established risk communication, behavior change, and behavioral economic principles) to be pre-recorded and sent out on these calls on a randomized basis (with approval by client organizations), with the number of arms to vary based on the size of each client's participant list (to ensure sufficient statistical power within each client's sample). Emmi will deliver the calls and track individual responses to questions posed during the call. Emmi will then provide a de-identified dataset to the academic research team for analysis to determine whether any scripts provided greater or lesser effects to people's their motivations to get a flu vaccination.
