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.

Condition or disease Intervention/treatment
Seasonal Influenza Behavioral: Planning Prompt Behavioral: Default Appointment Behavioral: Control

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.

Arm Intervention/treatment
Experimental: 1 Hour Planning Prompt Behavioral: Planning Prompt
Patients were prompted to write down a planned date (and in some cases time) for receiving a flu shot.
Experimental: 2 Hour Planning Prompt Behavioral: Planning Prompt
Patients were prompted to write down a planned date (and in some cases time) for receiving a flu shot.
Experimental: 1 Day Planning Prompt Behavioral: Planning Prompt
Patients were prompted to write down a planned date (and in some cases time) for receiving a flu shot.
Experimental: Default Planning Prompt Behavioral: Default Appointment
Patients were given a suggested date and time for receiving a flu shot.
Active Comparator: Control Behavioral: Control
Patients were provided with basic information (present in all conditions) about when and where they could receive a flu shot, but they were given no further treatment.
