Perceptions and tolerance of uncertainty: relationship to trust in COVID-19 health information and vaccine hesitancy.

ABSTRACT: The COVID-19 crisis has exposed the public to considerable scientific uncertainty, which may promote vaccine hesitancy among individuals with lower tolerance of uncertainty. In a national sample of US adults in May-June 2020, we examined how both perceptions of uncertainty about COVID-19 and trait-level differences in tolerance of uncertainty arising from various sources (risk, ambiguity, and complexity) are related to vaccine hesitancy-related outcomes, including trust in COVID-19 information, COVID-19 vaccine intentions, and beliefs that COVID-19 vaccines should undergo a longer testing period before being released to the public. Overall, perceptions of COVID-19 uncertainty were not associated with trust in information, vaccine intentions, or beliefs about vaccine testing. However, higher tolerance of risk was associated with lower intentions to get vaccinated, and lower tolerance of ambiguity was associated with lower intentions to get vaccinated and preferring a longer period of vaccine testing. Critically, perceptions of COVID-19 uncertainty and trait-level tolerance for uncertainty also interacted as predicted, such that greater perceived COVID-19 uncertainty was more negatively associated with trust in COVID-19 information among individuals with lower tolerance for risk and ambiguity. Thus, although perceptions of uncertainty regarding COVID-19 may not reduce trust and vaccine hesitancy for all individuals, trait-level tolerance of uncertainty arising from various sources may have both direct and moderating effects on these outcomes. These findings can inform public health communication or other interventions to increase COVID-19 vaccination uptake.

Project description:BackgroundInformation about Cameroonians' views toward coronavirus disease 2019 (COVID-19) and amenability to receiving a vaccine is emerging. Learning more about Cameroonians' vaccine perspectives could guide prevention messaging and facilitate optimal communication modalities.ObjectivesThe primary objective of this study was to analyze the willingness to receive a COVID-19 vaccine among Cameroonians, pending availability. The secondary objectives were to assess perceptions of COVID-19's origin and to gauge views toward government-mandated vaccinations.MethodsAn 11-item questionnaire queried Cameroonians in-person and online, from March through May 2021, about their demographics and whether they believed that COVID-19 was man-made, whether COVID-19 vaccinations should be governmentally mandated, and whether they would receive a COVID-19 vaccine, if available. A free-text option inviting rationales for COVID-19 vaccine hesitancy was included. In-person participation took place on the grounds of St. Louis University in Douala, Cameroon, and was restricted to participants lacking Internet access or electronic mobile devices. Online participation included use of an electronic link that contained questionnaire content located within Google Forms.ResultsA total of 591 respondents participated by replying to at least 8 items on the questionnaire, 386 online and 205 in-person. Over 80% stated that they previously received a seasonal influenza vaccine. Roughly, 87% reported unwillingness to receive a COVID-19 vaccine, if available. Approximately 95% of respondents disagreed with governmental mandates on COVID-19 vaccinations. About 75% attributed COVID-19 to man-made as opposed to natural beginnings. Seven respondents' free-text comments cited lacking confidence in a COVID-19 vaccine, discriminatory COVID-19 vaccine distribution patterns in other parts of the world relative to Africa, and improper COVID-19 vaccine approval timeline.ConclusionRaising awareness of COVID-19 misconceptions and barriers to vaccine acceptance is integral to accomplishing immunization goals. Cameroonians' pessimism in this study toward COVID-19 vaccination was multifaceted. Our findings signal a need for additional research that requests more qualitative insights, for example, interviews, focus groups, into vaccine aversion.

Project description:BackgroundAlthough numerous studies have been published on the predictors of COVID-19 vaccine hesitancy, some possible predictors remain underexplored. In this study, we explored the associations of unwillingness and indecisiveness regarding COVID-19 vaccination with generalized trust, mental health conditions such as depression and generalized anxiety, and fear of COVID-19.MethodsData of wave 1 (from October 27 till November 6, 2020) and wave 3 (from April 23 till May 6, 2021) of a longitudinal online study conducted in Japan were used for the analyses. Unvaccinated participants were asked at wave 3 about their willingness to be vaccinated, with possible responses of willing, unwilling, or undecided. These three responses were used as the outcome variable, and multinomial logistic regression analyses were conducted with willingness to be vaccinated as the reference group. Explanatory variables included generalized trust, depression, generalized anxiety, and fear of COVID-19 both at wave 1 and 3, and sociodemographic and health-related variables.ResultsOf the 11,846 valid respondents, 209 (1.8%) answered that they had already been vaccinated against COVID-19, 7089 (59.8%) responded that they were willing to be vaccinated, 3498 (29.5%) responded that they were undecided, and 1053 (8.9%) responded that they were unwilling to be vaccinated. After adjusting for covariates, we found that: (1) participants with lower levels of generalized trust at wave 1 and 3 were more likely to be undecided or unwilling at wave 3; (2) respondents with moderately severe or severe depression at wave 1 and 3 were more likely to be undecided at wave 3; (3) participants with moderate or severe levels of generalized anxiety at wave 3 but not at wave 1 were more likely to be unwilling at wave 3; and (4) respondents with high levels of fear of COVID-19 at wave 1 and 3 were less likely to be undecided and unwilling at wave 3.ConclusionsGeneralized trust, mental health conditions such as depression and generalized anxiety, and low level of fear of COVID-19 are associated with unwillingness or indecision regarding being vaccinated against COVID-19.
