An interventional study of Vaccine Norms Feedback and Alcohol Norms Feedback in COVID-19 and Vaccine Hesitancy, sponsored by University of Washington. Status unknown at 1 site in United States. Open to participants aged 18 Years to 24 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2023-03-28.
Sponsored by University of Washington · Not applicable, Interventional, and Prevention
Rationale: The highest rates of coronavirus disease (i.e., COVID-19) vaccine hesitancy in the US are among young adults (YAs) aged 18-25. Our preliminary studies show that social norms - perceptions of peers' vaccination attitudes/behaviors - are most strongly related to YAs' vaccine intentions/uptake. Most YAs underestimate the perceived importance of vaccination and their peers' intentions to be vaccinated. The proposed research will develop and test an intervention to correct misperceived norms for vaccination hesitancy and uptake.
Methodology: Rapid prototyping with 20 unvaccinated YAs will help refine the content and design of the online intervention. Then, a diverse national sample (N=600) of unvaccinated YAs will be randomized to treatment or an attention-matched control. The treatment condition will receive personalized normative feedback (PNF) designed to correct normative misperceptions for vaccine hesitancy and uptake.
Normative feedback will be derived from the US Census Bureau's Household Pulse Survey. Follow-up surveys will be administered at 1, 2, 3, and 6 months to assess key outcomes including vaccine uptake, intentions, and reasons for vaccine hesitancy.
Aims and Data Analysis:
Impact: Findings will clarify the causal role of psychological determinants of vaccine hesitancy (social norms, intellectual humility, group identification). If preliminary intervention efficacy is supported, this intervention could be a low-cost, and easily disseminated strategy to promote YAs' vaccine uptake and contribute to public health efforts to address the COVID-19 pandemic.

Counted across the registry records on this site, refreshed daily.
Exclusion Criteria:
The participants in the treatment condition will receive personalized normative feedback (PNF) that entails correcting normative misperceptions for US young adults' vaccine uptake rates and prevalence of vaccine hesitancies (e.g., fear of side effects). Participants will be shown discrepancies between their perceived estimate of young adults' vaccination rates and actual national estimates derived from the US Census Bureau's Household Pulse Survey to highlight, in most cases, that they underestimated the vaccination norms.
Behavioral: Vaccine Norms Feedback
Participants randomized to control will complete all measures at the same time as participants in the treatment condition, but will not receive any normative information regarding vaccines. Instead, to match for attention and provide potential benefit, those in the control condition will receive a standard dynamic norms feedback pertaining to alcohol use norms and behaviors.
Behavioral: Alcohol Norms Feedback
Personalized normative feedback pertaining to normative misperceptions about vaccination rates and hesitant attitudes.
Personalized normative feedback pertaining to normative misperceptions about alcohol use.
