Understanding factors associated with intent to receive the COVID-19 vaccine

As of December 1, 2020, when the Advisory Committee on Immunization Practices published their COVID-19 vaccine distribution and prioritization recommendations, health care workers (HCWs) and the elderly were deemed to be at greatest risk of contracting the coronavirus. Limited extant research suggests that most HCWs are willing to receive the COVID-19 vaccine, and findings from studies examining vaccine uptake in non-HCW samples also have reported high vaccination willingness. The health belief model (HBM) and the theory of planned behavior (TPB) suggest that beliefs about severity and susceptibility of disease, perceived benefits of and obstacles to vaccination, and normative beliefs of others affect vaccine uptake. Further, perceptions of safety, side effects, and demographic factors can uniquely impact COVID-19 vaccine uptake.

Using a cross-sectional design, we recruited 526 participants via social media, through snowball emailing methods, and from university settings.

The present findings demonstrate that 37% of participants intend to get the vaccine, and 35% reported that they might get the vaccine. No relationships among demographic factors, willingness to receive the vaccine, and level of intent were observed. However, those who reported that they would not receive the COVID-19 vaccine demonstrated fewer positive attitudes, less agreement, fewer normative views, and less anticipatory regret regarding the COVID-19 vaccine. Also, perceptions of susceptibility, severity, and barriers were associated with participants' willingness to get the COVID-19 vaccine.

Our results suggest that factors related to the HBM and TPB might uniquely impact COVID-19 vaccine acceptability and could guide the crafting of interventions meant to encourage vaccine uptake. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
