Healthcare provider Communication and Data-Informed Message Strategies for Encouraging Older Adults to Stay up to Date on COVID-19 Vaccination.

Older adults are a high in risk of severe COVID-19 disease outcomes and experience "vaccine hesitancy." Guided by health communication models such as the Reasoned Action Approach and the Extended Parallel Process Model, online surveys designed to inform statewide public health communication efforts were administered in West Virginia, a primarily rural and fully Appalachian state, in Winter 2021 ( = 272) and Fall 2022 ( = 248). Adults ages 50+ years ( = 520) reported attitudes, intentions, and behaviors regarding COVID-19 vaccination and their related patient-provider communication. Vaccine usefulness/safety, perceived effectiveness, and subjective norms predicted behavior while perceived severity, efficacy, and usefulness/safety predicted intention to get a booster, specifically the updated Fall 2022 Omicron (bivalent) booster. As patient-provider communication (which a minority reported receiving) was a strong predictor of behavioral outcomes, characteristics of effective healthcare provider communication and considerations for public message construction are discussed.
