What is ‘confidence’ and what could affect it?: A qualitative study of mothers who are hesitant about vaccines

Abstract

BackgroundPublic confidence in immunization is critical to maintaining high vaccine-coverage rates needed to protect individuals and communities from vaccine-preventable diseases. Recent attention has been placed on factors influencing confidence in vaccination in the US and globally, but comprehensive understanding of what drives or hinders confidence in childhood vaccination is yet to be reached. As such, assessing parents' confidence in childhood vaccination and the ways in which educational materials affect confidence is needed. ObjectiveWe sought to (1) learn how mothers who are hesitant about vaccination characterize confidence in health-related products for young children, including the recommended vaccines; (2) gain insights on what influences vaccine confidence beliefs; and (3) assess whether short, education materials affect parental confidence in childhood vaccinations. MethodsEight moderator-lead focus groups (n=61), stratified by socioeconomic status, were undertaken with mothers of children 5years of age of less who are hesitant about vaccines. Four of the groups were held in the Philadelphia, PA area and four were held in the San Francisco/Oakland, CA area. Three educational material pairs, each consisting of a 2–3min video and an infographic poster about an immunization-related topic, were reviewed and assessed for influence on confidence. ResultsQualitative data analysis was used to identify overarching themes across the focus groups. Themes, insights, and illustrative quotes were identified and provided for each of the major discussion areas: primary health concerns for young children; confidence beliefs and perceptions, including for recommended vaccines; facilitators and barriers to confidence; and reactions to the educational materials. ConclusionsResults provide helpful insights into how mothers who are hesitant about vaccines perceive confidence in childhood vaccines and health-related products, suggestions for how to improve confidence, and support for the value and use of short videos as part of vaccination education efforts. Findings can aid those developing vaccination education materials and resources designed to foster vaccine confidence.
