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.

A longitudinal assessment of variability in COVID-19 vaccine hesitancy and psychosocial correlates in a national United States sample.

Recent evidence suggests that COVID-19 vaccine hesitancy is not static. In order to develop effective vaccine uptake interventions, we need to understand the extent to which vaccine hesitancy fluctuates and identify factors associated with both between- and within-person differences in vaccine hesitancy. The goals of the current study were to assess the extent to which COVID-19 vaccine hesitancy varied at an individual level across time and to determine whether disgust sensitivity and germ aversion were associated with between- and within-person differences in COVID-19 vaccine hesitancy. A national sample of U.S. adults (N = 1025; 516 woman; Mage = 46.34 years, SDage = 16.56, range: 18 to 85 years; 72.6 % White) completed six weekly online surveys (March 20 - May 3, 2020). Between-person mean COVID-19 vaccine hesitancy rates were relatively stable across the six-week period (range: 38-42 %). However, there was considerable within-person variability in COVID-19 vaccine hesitancy. Approximately, 40 % of the sample changed their vaccine hesitancy at least once during the six weeks. There was a significant between-person effect for disgust sensitivity, such that greater disgust sensitivity was associated with a lower likelihood of COVID-19 vaccine hesitance. There was also a significant within-person effect for germ aversion. Participants who experienced greater germ aversion for a given week relative to their own six week average were less likely to be COVID-19 vaccine hesitant that week relative to their own six-week average. This study provides important information on rapidly changing individual variability in COVID-19 vaccine hesitancy on a weekly basis, which should be taken into consideration with any efforts to decrease vaccine hesitancy and increase vaccine uptake. Further, these findings identify-two psychological factors (disgust sensitivity and germ aversion) with malleable components that could be leveraged in developing vaccine uptake interventions.

The behavioral immune system and use of transportation services during the COVID-19 pandemic.

Introduction: A primary means of reducing the spread of COVID-19 is avoidance of close contact with other people, particularly in closed areas. Transportation services generally require being in closed spaces with other people, which has resulted in a significant reduction in use during the COVID-19 pandemic. Understanding individual differences associated with likelihood of using transportation services may help in targeting individuals that are hesitant to use these services. Specifically, psychological processes that encourage disease avoidance (e.g., disgust sensitivity, germ aversion) may play a key role in people's hesitancy to use transportation services. The aim of this study was to identify demographic groups that were hesitant to use transportation services during the COVID-19 pandemic and determine the extent to which individual differences in disease avoidance processes are associated with the likelihood of using transportation services during the COVID-19 pandemic. Method: A national sample of U.S. adults (N = 947) completed an online survey about the likelihood of using transportation services (i.e., public transportation, rental car, ride share, intercity trains, intercity buses, and commercial flight), germ aversion, disgust sensitivity, demographics, and control variables (e.g., COVID-19 concern). Results: Regression analyses indicated that greater germ aversion was associated with lower likelihood of transportation use for all measured transportation services, controlling for disgust sensitivity, demographics, and control variables. Older age and higher COVID-19 concern were associated with lower likelihood of using most of the transportation services, while town size was associated with greater likelihood of using public transportation and ride share. Discussion: Overall, germ aversion was consistently uniquely associated with lower likelihood of transportation service use. In the process of getting back to normal after the COVID-19 threat is reduced, structuring messages that target hesitant populations and use malleable psychological mechanisms like disease avoidance may aid in encouraging behavior change and increase transportation service use.

Associations between adolescents' prosocial experiences and mental health during the COVID-19 pandemic.

Natural disasters and times of crisis, such as the COVID-19 pandemic, are extremely stressful events, with severe mental health consequences. However, such events also provide opportunities for prosocial support between citizens, which may be related to mental health symptoms and interpersonal needs. We examined adolescents' prosocial experiences as both actors and recipients during the early stages of the COVID-19 pandemic and assessed whether these experiences were associated with indicators of mental health. Adolescents (N = 426; 78% female) aged 13 to 20 years (M age = 16.43, SD = 1.10; 63.6% White, 12.9% Hispanic/Latinx, 8.5% Asian, 4.2% Black, 2.8% Native American) were recruited across the US in early April of 2020. Participants reported on their COVID-19 prosocial experiences (helping others, receiving help) and mental health (depressive symptoms, anxiety symptoms, burdensomeness, belongingness). Multiple regression models indicated greater engagement in COVID-19 prosocial behavior was associated with greater anxiety symptoms and greater burdensomeness. Receiving more COVID-19 help was associated with lower depressive symptoms and higher belongingness. Findings highlight the importance of furthering our understanding of the nuanced connections between prosocial experiences and adolescents' mental health to help inform post-pandemic recovery and relief efforts.

Predictors of Change in Mental Health during the COVID-19 Pandemic.

BACKGROUND: Cross-sectional data suggest that depression, anxiety, and stress have increased during the COVID-19 pandemic. However, longitudinal research is needed to test changes in mental health and determine factors that contribute to change. The purpose of this study was to compare anxiety, depression, and stress pre-pandemic to during the pandemic within the same sample and identify predictors of change (i.e., disease threat, changes to daily life, social isolation, financial worries). METHOD: Three national samples of U.S. adults were recruited through an online platform (Amazon's Mechanical Turk). Participants completed online surveys pre-pandemic (September - December 2019) and during the pandemic(April - June 2020). RESULTS: Across the three samples, mini-meta analyses revealed significant increases in anxiety and stress (Cohen's ds = 0.17, 0.16, respectively; ps < 0.01). Financial concern and effects of COVID-19 on daily life predicted higher levels of depression, anxiety, and stress during the pandemic across all three samples (ds = 0.24, 0.40, and 0.40, respectively; ps < 0.001). LIMITATIONS: Response rates for follow-up surveys were relatively low, with some noted differences between those who did and did not complete both surveys. CONCLUSIONS: Significant increases in anxiety and stress were observed across three samples of U.S. adults from before to during the COVID-19 pandemic. Financial concern and effects of the pandemic on daily life emerged as the most consistent predictors of psychological distress across these samples.

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.

Mindfulness and engagement in COVID-19 preventive behavior.

The novel coronavirus disease 2019 (COVID-19) pandemic represents a significant risk to population health. Health organizations worldwide have recommended numerous preventive health behaviors to slow the spread of COVID-19. Yet, considerable variability exists in individual-level adherence to these recommendations. Mindfulness has been associated with greater engagement in health promotive behavior (e.g., physical activity, healthy eating), and may serve as an individual difference factor that encourages adherence. However, no study to date has examined the extent to which mindfulness is associated with preventive health behaviors during a global pandemic. The purpose of the present study was to assess the relations between mindfulness and recommended preventive health behaviors for COVID-19. A national U.S. sample (N = 353; M age = 41.47 years, range: 19-84; 50.2% female) completed an online survey via Amazon's Mechanical Turk from April 3rd to 15th, 2020, including measures of mindfulness and frequency of avoiding touching one's face, handwashing, disinfecting/cleaning frequently used surfaces, social distancing, and self-quarantining. Personality, health risk, and demographic factors were also assessed to test the unique association between mindfulness and preventive health behaviors. Mindfulness was significantly correlated with greater engagement in all of the COVID-19 preventive health behaviors. However, when accounting for demographics, health risk, and personality, mindfulness was only uniquely associated with engagement in social distancing. This research highlights mindfulness as an individual-level characteristic associated with engagement in COVID-19 preventive health behavior and may inform future prevention efforts aimed at improving adherence to recommendations for curbing the spread of infectious disease.

COVID-19 worries and mental health: the moderating effect of age.

BACKGROUND: Older age (60+ years) increases the risk of contracting and dying from coronavirus disease 2019 (COVID-19), which might suggest worse mental health for those in this age range during the pandemic. Indeed, greater worry about COVID-19 is associated with poorer mental health. However, older age is generally associated with better emotional well-being, despite increased likelihood of negative events (e.g. death of a spouse) with age. This study examined whether age moderated the relation between COVID-19 worries and mental health. METHODS: A national sample of U.S. adults (N = 848; aged 18-85 years) completed an online survey from March 30 to April 5, 2020. The survey assessed anxiety, depression, general concern about COVID-19, perceived likelihood of contracting COVID-19, social distancing, self-quarantining, current mood, health, and demographics. RESULTS: Older age was associated with better mental health (i.e. lower levels of anxiety and depression). Greater perceived likelihood of contracting COVID-19 was related to higher anxiety. However, this effect was moderated by age. At younger ages (18-49 years), the positive association between perceived likelihood of contracting COVID-19 and anxiety was significant, but the association was not significant at older ages (50+ years). CONCLUSION: Older age may buffer against the negative impact of the COVID-19 pandemic on mental health. More research is necessary to understand the potential protective nature of age during the pandemic, as well as the recovery period.

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.
