The Effect of Time-Slot Scheduling on Flu Vaccination Rates

Not Applicable

Completed

• Conditions: Seasonal Influenza

• Registration Number: NCT01206686
• Lead Sponsor: University of Pennsylvania

Brief Summary

The goal of this project is to see if encouraging an individual to privately choose in advance a narrow time window in which to obtain a flu vaccination shot affects the likelihood that he or she will become vaccinated.

Detailed Description

Influenza causes 36,000 U.S. deaths per year, but influenza immunization rates average just 28%. Behavioral "nudges" may increase the effectiveness of immunization reminder mailers at little or no added cost. Past psychology research has demonstrated that prompting people to form an implementation plan of the form, "When situation x arises, I will implement response y," increases attainment of desired goals because the desired behavior is linked to a concrete future moment. We study whether adding a planning prompt to a vaccination reminder mailer increases immunization rates.
