Psychosocial Factors Predict Mask-Wearing: A Longitudinal Study Across 3 Phases of the COVID-19 Pandemic.

Determinants of mask-wearing during a pandemic range from the personal to the political. Using a repeated measures design, we examined psychosocial predictors of self-reported mask-wearing 3 times during the early stage of the COVID-19 pandemic. Participants completed surveys at baseline (summer 2020), 3 months (fall 2020), and 6 months (winter 2020-2021). The survey assessed the frequency of mask-wearing and psychosocial predictors from various theories, including fear of COVID-19, perceived severity, perceived susceptibility, attitude, health locus of control, and self-efficacy. Results indicated that the strongest predictors of mask-wearing varied as a function of the stage in the pandemic. In the earliest phase, fear of COVID-19 and perceived severity were the strongest predictors. Three months later, attitude was the strongest predictor. Finally, another 3 months later, self-efficacy became the strongest predictor. Overall, the results suggest that the primary determinants of a novel protective behavior shift over time and with increased familiarity.

The Nature and Extent of COVID-19 Vaccination Hesitancy in Healthcare Workers.

COVID-19 vaccines were approved in late 2020 and early 2021 for public use in countries across the world. Several studies have now highlighted COVID-19 vaccination hesitancy in the general public. However, little is known about the nature and extent of COVID-19 vaccination hesitancy in healthcare workers worldwide. Thus, the purpose of this study was to conduct a comprehensive worldwide assessment of published evidence on COVID-19 vaccine hesitancy among healthcare workers. A scoping review method was adopted to include a final pool of 35 studies in this review with study sample size ranges from n = 123 to 16,158 (average = 2185 participants per study). The prevalence of COVID-19 vaccination hesitancy worldwide in healthcare workers ranged from 4.3 to 72% (average = 22.51% across all studies with 76,471 participants). The majority of the studies found concerns about vaccine safety, efficacy, and potential side effects as top reasons for COVID-19 vaccination hesitancy in healthcare workers. The majority of the studies also found that individuals who were males, of older age, and doctoral degree holders (i.e., physicians) were more likely to accept COVID-19 vaccines. Factors such as the higher perceived risk of getting infected with COVID-19, direct care for patients, and history of influenza vaccination were also found to increase COVID-19 vaccination uptake probability. Given the high prevalence of COVID-19 vaccine hesitancy in healthcare workers, communication and education strategies along with mandates for clinical workers should be considered to increase COVID-19 vaccination uptake in these individuals. Healthcare workers have a key role in reducing the burden of the pandemic, role modeling for preventive behaviors, and also, helping vaccinate others.
