Comparative Tests of Flu Vaccination Phone Messages

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.
