Brief 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.

Outcome Measures
Primary Outcomes (1)
Vaccination intentions (Time 1)
Question (language being manipulated) asking whether respondent intends to vaccinate
Day 1 (Assessed during the intervention telephone call)
Secondary Outcomes (1)
Documented influenza vaccination
Within 6 months / during 2017-2018 influenza season
Study Arms (6)
Viral changes + General intentions
EXPERIMENTALScript language discusses a) that previous years' shots do not protect against current year influenza (viral changes) and b) poses a general question asking whether the respondent intends to get a flu shot (general intentions).
Viral changes + Behavioral intentions
EXPERIMENTALScript language discusses a) that previous years' shots do not protect against current year influenza (viral changes) and b) poses a question asking when / where the respondent will get a flu shot (behavioral intention).
Viral changes + Accountability
EXPERIMENTALScript language discusses a) that previous years' shots do not protect against current year influenza (viral changes) and b) poses a question that implies the patient's care team will be notified of intent to vaccinate (accountability to providers).
Protect others + General intentions
EXPERIMENTALScript language discusses a) that getting the flu shot protects others who can get particularly sick (protect others) and b) poses a general question asking whether the respondent intends to get a flu shot (general intentions).
Protect others + Behavioral intentions
EXPERIMENTALScript language discusses a) that getting the flu shot protects others who can get particularly sick (protect others) and b) poses a question asking when / where the respondent will get a flu shot (behavioral intention).
Protect others + Accountability
EXPERIMENTALScript language discusses a) that getting the flu shot protects others who can get particularly sick (protect others) and b) poses a question that implies the patient's care team will be notified of intent to vaccinate (accountability to providers).
Interventions
Telephone script language provided pre-questions regarding the fact that influenza viruses change each year
Telephone script language provided pre-questions emphasizing the need to protect vulnerable others
Question language asking about general interest in getting influenza vaccination
Question language asking individual to make specific plans to be vaccinated
Question language asking individual whether their care team can learn about their vaccination intentions
