Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Parents emphasize different moral foundations when deciding whether or not to vaccinate children. Based on this research, a messaging intervention with parents of children who are 12 years of age or younger will be conducted. These messages will aid in assessment of how different moral foundations impact attitudes towards vaccination and intent to vaccinate.
This study tests the impact of targeted vaccine-focused health messages on vaccine beliefs held by parents of young children and pre-adolescents. The participant's vaccine beliefs will be assessed at baseline. Two weeks later, the participant's moral matrix will be assessed. A vaccine-related message that appeals to the individual's three most or least emphasized moral foundations will then be presented. Immediately afterwards, vaccine beliefs will be assessed to determine the impact of the message.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Morally Congruent Message
Participants randomized to this arm will receive a vaccine-related message developed to appeal to their three most-emphasized moral foundations.
Baseline Survey
The baseline survey contains questions regarding level of existing vaccine hesitancy (Parent Attitudes about Childhood Vaccines (PACV) short scale and HealthStyles questions), demographic information, and intent to vaccinate their children. All study surveys will be completed on an electronic device.
Pre-intervention Survey
Participants will be contacted two weeks after completing the baseline survey to answer questions about their moral beliefs. The survey will include questions form the Moral Foundations Questionnaire as well as additional questions. An algorithm will calculate the participant's moral matrix based on answers to these questions.
Morally Congruent Message
Intervention messages consist of four short paragraphs. The first three focus on how getting vaccinated helps uphold specific moral foundations. The fourth summarizes the contents of the prior paragraphs.
Participants randomized to the morally congruent arm will receive a vaccine-related message developed to appeal to their three most-emphasized moral foundations. The first paragraph focuses on the most emphasized foundation, the second on the third-most emphasized, and the third on the second-most emphasized.
Post-Intervention Survey
Immediately after reading the randomly assigned message participants will complete a follow-up survey assessing level of existing vaccine hesitancy (PACV short scale and HealthStyles questions) and intent to vaccinate their children.
Morally Non-Congruent Message
Participants randomized to this arm will receive a vaccine-related message developed to appeal to their three least-emphasized moral foundations.
Baseline Survey
The baseline survey contains questions regarding level of existing vaccine hesitancy (Parent Attitudes about Childhood Vaccines (PACV) short scale and HealthStyles questions), demographic information, and intent to vaccinate their children.

The first paragraph focuses on the least emphasized foundation, the second on the third-least emphasized, and the third on the second-least emphasized.
Post-Intervention Survey
Immediately after reading the randomly assigned message participants will complete a follow-up survey assessing level of existing vaccine hesitancy (PACV short scale and HealthStyles questions) and intent to vaccinate their children.
Control Message
Participants randomized to the control arm will be provided with a short passage about the costs and benefits of bird feeding.
