Behavioral Intervention, Influenza Vaccine, Self-benefit, Social-benefit
Conditions
Brief summary
Influenza vaccine uptake remains low worldwide, inflicting substantial costs to public health and health systems. Messages promoting social welfare have been shown to increase vaccination intentions, and it has been recommended that health professionals communicate the socially beneficial aspects of vaccination. This study aims to provide the first test whether this prosocial vaccination hypothesis applies to the actual vaccination behaviour of high-risk patients by comparing the effects of two motivational messages for promoting vaccination at a tertiary care public hospital in Istanbul, Turkey.
Interventions
BEHAVIORALSelf-benefit message
A pamphlet consisting of a short text and an abstract figure. The top half of the pamphlet described the official criteria for qualifying to be in the risk group. Bottom half indicated that one can gain immunity against influenza by getting the vaccine and included a figure of one smiley face.
BEHAVIORALOther-benefit message
A pamphlet consisting of a short text and an abstract figure. The top half of the pamphlet described the official criteria for qualifying to be in the risk group. Bottom half indicated that one can gain immunity against influenza by getting the vaccine, and gaining immunity would lower the chances of transmitting the disease to others. The figure included one smiley face surrounded by three other smiley faces.
