Addressing COVID-19 Vaccine Hesitancy With Muliti-Level Interventions in Appalachia
Purpose
The purpose of this community-engaged study is to test the ability of county-level strategies to increase uptake of COVID-19 vaccination. In this study the key objective is to test whether health communication strategies or health communication + county-specific structural/environmental support increases COVID-19 vaccine uptake and changes perceptions and beliefs about the vaccination at the county-level.

Arm Groups
Arm | Description | Assigned Intervention |
---|---|---|
Experimental Health Communication |
This intervention arm will include exclusively health communication messaging strategies that is both theory-based and community-targeted to encourage uptake of the COVID-19 vaccine delivered by trusted local communicators. Pre-identified theory-based components are attitudes, social norms, perceived behavioral control, response efficacy, and implementation intentions. The development process for the messaging will be based through a conjoint process of identification of theory- based determinants of decision-making relevant to the desired behavior change and a community-engaged process of identifying: a) community-specific messaging themes; b) trusted communicators within the target population; and c) community-specific messaging, imaging, and themes to achieve targeting. |
|
Experimental Health Communication + Structural |
This intervention arm will include the conditions outlined and included in the health communication arm, however, they will be coupled with a series of structural and/or environmental intervention strategies as well, which are targeted to facilitate vaccine accessibility and uptake among adults in the randomly assigned study counties. |
|
No Intervention Standard of Care |
No study-specific intervention strategies (as outlined above) will be implemented in control counties at the time of the study period. Any ongoing and/or pre-existing efforts within the scope of the project's outcomes will continue as it would have i.e. a health department operating a health fair. |

Detailed Description
The intervention trial will be a community-based, three-arm cluster randomized controlled trial. The three arms are: (1) multilevel invention (vaccine communication campaign + community-level structural intervention),(2) health communications only intervention, and (3) control/standard of care. Randomization will take place at the county level. The 15 participating counties will first be matched into blocks of three, with each block being matched as closely as possible on recent county influenza vaccination rates. After matching, the three counties within each matched block will be randomly assigned to one of the three study arms. This technique of randomizing to study arm within each matched block of counties increases confidence that community-level factors that might influence vaccine uptake are equally distributed across study arms. Following randomization, the intervention process will begin in counties in the multilevel and communication campaign intervention arms. Assessment of primary and secondary study outcomes will take place 6 months after initiation of the intervention. Finally, after assessment of outcomes is complete, the intervention components will be offered to the control counties.
