An interventional study of Baseline Survey and Pre-intervention Survey in Childhood Vaccinations, sponsored by Emory University. Completed at 1 site in United States. Open to participants aged 18 Years to 50 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2017-03-10.

This study is the first phase of a trial examining decision making about vaccines. This phase 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.
Vaccination of young children helps protect this population against a variety of diseases. Children are especially at risk for contraction of and complications from diseases due to their vulnerable immune systems. New evidence-based messages are needed to maintain and increase vaccination uptake among this group. An emphasis on different values is related to decisions parents make about vaccines. The purpose of this study is to develop, implement, and evaluate messages that focus on different aspects of values to impact vaccination attitudes among parents of young children.
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.

Exclusion Criteria:
Participants randomized to this arm will receive a vaccine-related message developed to appeal to their three most-emphasized moral foundations.
Behavioral: Baseline Survey · Behavioral: Pre-intervention Survey · Behavioral: Morally Congruent Message · Behavioral: Post-Intervention Survey
Participants randomized to this arm will receive a vaccine-related message developed to appeal to their three least-emphasized moral foundations.
Behavioral: Baseline Survey · Behavioral: Pre-intervention Survey · Behavioral: Morally Non-Congruent Message · Behavioral: Post-Intervention Survey

Behavioral: Baseline Survey · Behavioral: Pre-intervention Survey · Behavioral: Control Message · Behavioral: Post-Intervention 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.
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.
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.
Also known as: Morally Congruent Vaccine Focused Message
Intervention messages consist of four short paragraphs. The first three focus on how getting vaccinated helps uphold specific moral foundations. Participants randomized to the morally non-congruent arm will receive a vaccine-related message developed to appeal to their three least-emphasized moral foundations. The first paragraph focuses on the least emphasized foundation, the second on the third-least emphasized, and the third on the second-least emphasized.
Also known as: Morally Non-Congruent Vaccine Focused Message
Participants randomized to the control arm will be provided with a short passage about the costs and benefits of bird feeding.
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.
