Is disgust proneness prospectively associated with influenza vaccine hesitancy and uptake?

Although various demographic and psychosocial factors have been identified as correlates of influenza vaccine hesitancy, factors that promote infectious disease avoidance, such as disgust proneness, have been rarely examined. In two large national U.S. samples (Ns = 475 and 1007), we investigated whether disgust proneness was associated with retrospective accounts of influenza vaccine uptake, influenza vaccine hesitancy, and eventual influenza vaccine uptake, while accounting for demographics and personality. Across both studies, greater age, higher education, working in healthcare, and greater disgust proneness were significantly related to greater likelihood of previously receiving an influenza vaccine. In Study 2, which was a year-long longitudinal project, disgust proneness prospectively predicted influenza vaccine hesitancy and eventual vaccine uptake during the 2020-2021 influenza season. Findings from this project expand our understanding of individual-level factors associated with influenza vaccine hesitancy and uptake, highlighting a psychological factor to be targeted in vaccine hesitancy interventions.

Job Insecurity and Financial Concern During the COVID-19 Pandemic Are Associated With Worse Mental Health.

OBJECTIVE: To determine whether job insecurity due to COVID-19 and financial concern were associated with worse mental health during the COVID-19 pandemic. METHOD: Participants (N = 474 employed U.S. individuals) completed an online survey from April 6 to 12, 2020. Linear regressions were used to examine factors associated with mental health. RESULTS: After accounting for demographic characteristics, health status, other COVID-19 experiences, and anxiety symptoms, greater job insecurity due to COVID-19 was related to greater depressive symptoms. Conversely, after accounting for covariates and depressive symptoms, greater financial concern was related to greater anxiety symptoms. Further, greater job insecurity was indirectly related to greater anxiety symptoms due to greater financial concern. CONCLUSIONS: Findings suggest that employers should aim to reduce job insecurity and financial concern among employees during the COVID-19 pandemic to address the associated mental health consequences.

Disease avoidance in the time of COVID-19: The behavioral immune system is associated with concern and preventative health behaviors.

The coronavirus disease 2019 (COVID-19) poses a serious global health threat. Without a vaccine, behavior change is the most effective means of reducing disease transmission. Identifying psychological factors that may encourage engagement in preventative health behaviors is crucial. The behavioral immune system (BIS) represents a set of psychological processes thought to promote health by encouraging disease avoidance behaviors. This study examined whether individual differences in BIS reactivity (germ aversion, pathogen disgust sensitivity) were associated with concern about COVID-19 and engagement in recommended preventative health behaviors (social distancing, handwashing, cleaning/disinfecting, avoiding touching face, wearing facemasks). From March 20 to 23, 2020, a US national sample (N = 1019) completed an online survey. Germ aversion and pathogen disgust sensitivity were the two variables most consistently associated with COVID-19 concern and preventative health behaviors, while accounting for demographic, health, and psychosocial covariates. Findings have implications for the development of interventions intended to increase preventative health behaviors.
