Risk perception as a motivational resource during the COVID-19 pandemic: the role of vaccination status and emerging variants.

BACKGROUND: People's perceived risk of being infected and having severe illness was conceived as a motivational source of adherence to behavioral measures during the COVID-19 crisis. METHODS: We used online self-reported data, spanning 20 months of the COVID-19 crisis in Belgium (n = 221,791; 34.4% vaccinated; July 2020 - March 2022) to study the association between risk perception and motivation. RESULTS: Both perceived infection probability and severity fluctuated across time as a function of the characteristics of emerging variants, with unvaccinated persons perceiving decreasingly less risk compared to vaccinated ones. Perceived severity (and not perceived probability) was the most critical predictor of autonomous motivation for adherence to health-protective measures, a pattern observed at both the between-day and between-person level among both vaccinated and unvaccinated individuals. An integrated process model further indicated that on days with higher hospitalization load, participants reported being more adherent because risk severity and autonomous motivation for adherence were more elevated on these days. CONCLUSIONS: These findings suggest that risk severity served as a critical and dynamic resource for adherence to behavioral measures because it fostered greater autonomous regulation.

The Role of Communication Style and External Motivators in Predicting Vaccination Experiences and Intentions: An Experimental Vignette Study.

This vignette-based study examined in a sample of unvaccinated Belgian citizens (N = 1918; Mage = 45.99) how health care workers could foster reflection about and intentions to get vaccinated against COVID-19 by experimentally varying their communication style (i.e., autonomy-supportive vs. controlling) and the reference to external motivators (i.e., use of a monetary voucher or corona pass vs. the lack thereof). Each participant was randomly assigned to one of six conditions and rated a vignette in terms of anticipated autonomy satisfaction, perceived effectiveness, reflection, and vaccination intention. An autonomy-supportive, relative to a controlling, communication style predicted greater autonomy need satisfaction, which in turn related positively to perceived effectiveness, reflection, and vaccination intention. External motivators failed to generate positive effects compared to the control condition. The findings highlight the critical role of autonomy support in promoting a self-endorsed decision to get vaccinated.

How do vaccination intentions change over time? The role of motivational growth.

OBJECTIVE: Across nationwide rollout of COVID-19 vaccination, people in Belgium differed widely in their vaccination intention. In the present study, we examined (a) how people's vaccination intentions changed during the vaccination rollout and (b) whether changes in motivation (i.e., autonomous, controlled, and distrust-based (a)motivation) predicted changes in vaccination intention, thereby taking into account people's vaccination intention at baseline. METHOD: Using 4 subsamples of participants who were vaccinated at different time points (ntotal = 10,799) between December 2020 and June 2021; we used latent change modeling and latent growth curve modeling to examine the associations among initial levels and changes in vaccination motivation and vaccination intention. RESULTS: Across subsamples, changes in vaccination intention were found to be qualified by changes in motivation. An increase in autonomous motivation was related to a positive shift in vaccination intention, while an increase in both controlled motivation and distrust-based amotivation was related to a negative shift in vaccination intention. Moreover, autonomous motivation predicted especially an increase in vaccination intention among those initially low in vaccination intention, whereas an increase in either controlled motivation or distrust-based amotivation especially predicted a decrease in vaccination intention among those initially high in vaccination intention. CONCLUSIONS: Findings suggest that a growing sense of ownership and a reduction in distrust is critical for individuals to develop a stronger intention to get vaccinated, particularly when people had initially low vaccination intentions. We discuss conceptual, methodological, and practical implications. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Who is motivated to accept a booster and annual dose? A dimensional and person-centered approach.

The transmissibility of new COVID-19 variants and decreasing efficacy of vaccines led authorities to recommend a booster and even an annual dose. However, people's willingness to accept new doses varied considerably. Using two independent longitudinal samples of 4596 (Mean age = 53.6) and 514 (Mean age = 55.9) vaccinated participants, we examined how people's (lack of) vaccination motivation for their first dose was associated with their intention to get a booster (Sample 1) and an annual dose (Sample 2) several months later (Aim 1). We also aimed to capture the impact of the motivational heterogeneity on these intentions by capitalizing on participants' different motivational profiles collected at baseline (Aim 2). Across both samples, autonomous motivation, controlled motivation, and distrust-based amotivation were uniquely related to, respectively, higher, lower, and even lower booster and annual dose intentions. Further, a two-step clustering procedure revealed five profiles, with the profiles characterized by higher autonomous motivation (i.e. Good Quality and High Quantity profiles) reporting the highest vaccination intentions and the profile characterized by the highest number of obstacles (i.e. Global Amotivated profile) yielding the lowest vaccination intentions. These results stress the critical need to support citizens' volitional endorsement of vaccination to harvest long-term benefits with respect to COVID-19.

Psychological need fulfillment as a source of resilience: Its protective role in concerns and symptoms of anxiety and depression during the COVID-19 pandemic.

The essential role of the psychological needs for autonomy, competence, and relatedness in well-being has been demonstrated convincingly. Yet whether their fulfillment also serves as a source of resilience in the face of adversity has received limited attention. A longitudinal sample of Belgian citizens (N = 1869; Mage = 56.23, 68% female) completed an online questionnaire on 13 occasions between April 2020 and April 2022 during the COVID-19 crisis. Multilevel analyses showed that need fulfillment, both at the between- and within-person level, related negatively to concerns, even after controlling for exposure to personal risks. Further, the association between concerns and changes in symptoms of depression and anxiety was dampened when people reported higher need fulfillment compared with others (i.e. between-person level) or when they reported periodically more need fulfillment than usual (i.e. within-person level). This moderation effect occurred on top of the systematic negative main effect of need fulfillment on symptoms of anxiety and depression. Psychological need fulfillment serves as a resilience factor (a) by reducing concerns in the face of adverse events (i.e. an appraisal effect) and (b) by mobilizing resources that help individuals to deal better with concerns (i.e. a coping effect). Theoretical and practical implications of the resilience effect of need fulfillment are discussed.

Looking for Ties with Secret Agendas During the Pandemic: Conspiracy Mentality is Associated with Reduced Trust in Political, Medical, and Scientific Institutions - but Not in Medical Personnel.

In a preregistered research, we examined the relationships between conspiracy mentality (i.e., the individual susceptibility to endorse conspiracy theories, Bruder et al., 2013) and trust in three actors of the COVID-19 crisis: 1) Political institutions, 2) scientific and medical institutions, and 3) the medical personnel. While the two former groups have played a direct or indirect role in decisions related to public health measures, the latter has not. We expected all these relationships to be negative and mediated by the belief that the pandemic is instrumentalized by authorities to pursue secret agendas. In a study conducted with Belgian (N = 1136) and French (N = 374) convenience samples, conspiracy mentality negatively predicted trust in political institutions, and trust in scientific and medical institutions. These relations were partly mediated by belief that the pandemic is instrumentalized by authorities. In addition, distrust in political, medical and scientific institutions were highly and positively correlated, suggesting that these groups may be viewed as part of a same supra-ordinate category - the "Elites". By contrast, we found a small negative relationship between conspiracy mentality and trust in the medical personnel in the Belgian sample, but not in the French sample. Trust in the medical personnel was unrelated to the belief that the pandemic is instrumentalized, and only weakly related to distrust in political institutions. This suggests that individuals with a susceptibility to believe in conspiracy theories may not have a propensity to distrust all actors involved in the management of the pandemic, but only those directly or indirectly tied to decisions pertaining to public health measures.

Predicting vaccine uptake during COVID-19 crisis: A motivational approach.

The present research examined which motivational factors contribute to individuals' intention to take a vaccine that protects against SARS-CoV-2-virus and their self-reported vaccine uptake several months later. The role of different types of motivation was investigated (i.e., autonomous and controlled regulation) as well as vaccine distrust and effort to obtain a vaccine. Across two large-scale cross-sectional (N = 8887) and longitudinal (N = 6996) studies and controlling for various covariates, autonomous motivation and distrust-based amotivation contributed positively and negatively, respectively, to a) concurrent vaccination intentions, b) self-reported vaccination and c) subsequent subscription to a waitlist to obtain a vaccine. Participants' infection-related risk perception predicted more positive vaccination outcomes through fostering greater autonomous motivation for vaccination and lower distrust, whereas pandemic-related health concerns failed to yield such adaptive effects. The results emphasize the importance of fostering autonomous motivation for vaccination and handling distrust.

The relation between conspiracism, government trust, and COVID-19 vaccination intentions: The key role of motivation.

RATIONALE: Vaccination willingness is a critical step in the effort to reach herd immunity and control the COVID-19 pandemic. Nevertheless, many people remain reluctant to be vaccinated. OBJECTIVE: Integrating the literature on Self-Determination Theory, trust in authorities, and conspiracy theories, this research examines (a) the direct and indirect effect of government trust and conspiracism via underlying forms of motivations for (not) getting vaccinated against COVID-19 and (b) whether these associations differ across the two largely politically independent Belgian linguistic groups. METHODS: Using Structural Equation Modeling, we tested our models in two independent samples, in February 2021 (T1) and April 2021 (T2) (Total N = 8264). RESULTS: At T1 and T2, Government trust and conspiracism both predict COVID-19 vaccination intention, respectively positively and negatively. These relations are fully mediated by motivational factors, with identified motivations having a larger positive contribution. Looking at linguistic context, differences emerge at T2, with French-speaking Belgians showing lower levels of government trust and higher levels of conspiracism than Dutch speakers. CONCLUSIONS: Results highlight the importance of integrating distal (trust in government, conspiracism) and proximal (motivational) variables to understand vaccination intentions.

Personal and contextual determinants of COVID-19 vaccination intention: a vignette study.

BACKGROUND: This vignette study explores which factors contribute to higher COVID-19 vaccination intentions. METHODS: Between the 4th-11 January 2021, we recruited 15,901 Belgian citizens (Mage = 50.11 years, range 18-100) through convenience sampling to participate in a vignette study. In each vignette, we manipulated contextual determinants consisting of different factors. Each participant rated six vignettes in terms of the outcomes 'vaccination intention' and 'recommendation to others.' Finally, we explored the benefits of tailored communication by examining whether these ratings depended upon citizens' initial motives for vaccination. RESULTS: Participants are most likely to accept a vaccine when they expect no or only small side effects, when the vaccine offers a 95% protection, and when people can no longer infect others (p < 0.001). The possibility to receive the vaccine at home or at the GP's office, highlighting that most citizens are willing to get vaccinated, and emphasizing the protective benefits for others yielded additional positive effects (p < 0.001). Results showed that tailored communication has a small but significant effect, especially for individuals high on distrust-based amotivation (p < 0.01). CONCLUSION: In addition to vaccine characteristics, there is room for policymakers to respond to those determinants that fall under their control and can thus be highlighted within communication campaigns.

Social control and solidarity during the COVID-19 pandemic: The direct and indirect effects of causal attribution of insufficient compliance through perceived anomie.

The COVID-19 pandemic is a crisis which called for two crucial modes of social regulation: social control and social solidarity. In the present pre-registered study, we examine how the perceived non-compliance with health measures relates to attitudes towards these modes of social regulation, as well as to the role played by the perception of disintegrated and disregulated society (anomie). Using data from an online cross-sectional survey conducted in Belgium in April 2020 (N = 717), results show that the causal attribution of the crisis to insufficient compliance was differentially associated with support for social control and social solidarity behaviours. Specifically, greater attribution to insufficient compliance was associated with a perceived breakdown in the social fabric (disintegration), which explained stronger support for social control and fewer solidarity-based actions. Perceived disregulation, conversely, was associated with less support for social control and more support for social solidarity. Therefore, the perception of the pandemic and associated perceived anomie tend to polarize citizens' attitudes towards these two modes of social regulation. In this way, prosocial behaviours might be inhibited by communications that attribute the pandemic's causes to incivility. Other implications of our findings for the social psychological literature on communities' reactions to the pandemic are discussed.
