Predicting vaccination hesitancy: The role of basic needs satisfaction and institutional trust.

Autonomous motivation is considered a powerful driver of health behaviour, but less is known about the specific roles played by basic needs. Drawing on the context of the COVID-19 pandemic, this research examined basic needs as a motivational determinant of vaccination. We hypothesized that satisfaction of basic needs (autonomy, competence, relatedness) has both a direct and an indirect effect (through trust in science and government) on vaccine hesitancy. Two studies (Study 1: N = 968 French and British; Study 2, pre-registered: N = 716 Americans) tested our hypotheses and compared vaccinated and non-vaccinated individuals using multigroup structural equation models. We found positive direct (in both studies) and indirect (in Study 1) effects of autonomy satisfaction on vaccine acceptance. In contrast, competence satisfaction was directly and indirectly, via science mistrust, related to vaccine hesitancy, particularly among non-vaccinated people. Competence satisfaction also indirectly reduced the intention to vaccinate in both studies. We found no impact of relatedness. Complementing previous work on self-determination theory, our research demonstrates the importance of considering the distinct roles of basic needs. Moreover, we highlight that increasing autonomy and science trust may be an efficient strategy to improve vaccine acceptance and vaccination, even among reluctant individuals.

Yes, we can (but for different reasons): Collective narcissism is linked to different values but similar pro-ingroup collective action tendencies among disadvantaged and advantaged ethnic groups.

Collective narcissism, a belief that one's group is exceptional and entitled to special treatment but underappreciated by others, is related to important social and political outcomes but has been predominantly studied in advantaged groups. The present research compares the motivational correlates (through values) of collective narcissism in ethnic groups of different status (advantaged and disadvantaged) and explores its associations with attitudes towards, and intention to engage in collective action. Three studies examined these processes in different national and intergroup contexts (total N = 16,275). Overall, ethnic collective narcissism was linked to self-protective values (power, and less consistently, conservation) in advantaged groups but to universalism in disadvantaged groups. Moreover, in both advantaged and disadvantaged groups, ethnic collective narcissism was related to more positive attitudes towards, and intentions of pro-ingroup actions but not to attitudes towards (other) disadvantaged groups (i.e., intergroup solidarity). These studies suggest that collective narcissism may be associated with different motivations, yet linked to similar intergroup attitudes among advantaged and disadvantaged groups.

Do it for others! The role of family and national group social belongingness in engaging with COVID-19 preventive health behaviors.

COVID-19 is an unprecedented threat and an effective response requires a collective effort: engagement in preventive health behaviors, even from people at low risk. Previous research demonstrates that belongingness to social groups can promote prosocial, preventive health behaviors. The current research tests the effects of belongingness to two types of groups, intimate (family) and social category (nation), on intentions to comply with preventive health behaviors and reasons for these behaviors. We conducted three studies using French participants at low risk of grave effects from COVID-19 (total N = 875). In Study 1, across three time periods, belongingness was correlated with greater intentions to comply with preventive behaviors when these behaviors were not enforced by law. In Study 2, we experimentally manipulated threat to belongingness (vs. no threat). When belongingness was threatened, participants were less concerned with protecting vulnerable people. Closeness to family predicted preventive behavior intentions and both self-centered and prosocial reasons for these behaviors, regardless of condition. National identification buffered the negative effects of the threat to belongingness condition on preventive behavior intentions. In Study 3, we experimentally primed thoughts of belongingness to family vs. nation vs. control condition. We found greater intentions to engage in preventive behaviors and greater concern with protecting oneself and close relatives in the family condition. In summary, belongingness to one's family promotes preventive behavior intentions and the reasons given are to protect both oneself and others. Self-reported (but not primed) national identification can be related to prevention behavior intentions under certain conditions.

Antecedents and consequences of COVID-19 conspiracy beliefs: A systematic review.

RATIONALE: Belief in COVID-19 conspiracy theories can have severe consequences; it is therefore crucial to understand this phenomenon, in its similarities with general conspiracy belief, but also in how it is context-dependent. OBJECTIVE: The aim of this systematic review is to provide a comprehensive overview of the available research on COVID-19 conspiracy beliefs and to synthesise this research to make it widely accessible. METHODS: We present a synthesis of COVID-19 conspiracy belief research from 85 international articles, identified and appraised through a systematic review, in line with contemporary protocols and guidelines for systematic reviews. RESULTS: We identify a number of potential antecedents of COVID-19 conspiracy beliefs (individual differences, personality traits, demographic variables, attitudes, thinking styles and biases, group identity, trust in authorities, and social media use), their consequences (protective behaviours, self-centred and misguided behaviours such as hoarding and pseudoscientific health practices, vaccination intentions, psychological wellbeing, and other negative social consequences such as discrimination and violence), and the effect sizes of their relations with the conspiracy beliefs. CONCLUSIONS: We conclude that understanding both the potential antecedents and consequences of conspiracy beliefs and how they are context-dependent is highly important to tackle them, whether in the COVID-19 pandemic or future threats, such as that of climate change.

Looking out for myself: Exploring the relationship between conspiracy mentality, perceived personal risk, and COVID-19 prevention measures.

OBJECTIVES: This research examined how conspiracy mentality may affect compliance with preventive health measures necessary to fight the COVID-19 pandemic, and the underlying motivations to comply. DESIGN AND METHOD: We conducted two cross-sectional studies (Study 1 N = 762, Study 2 N = 229) on a French population, measuring conspiracy mentality, compliance with preventive health measures, and perceived risks related to COVID-19. We also measured motivations to comply with preventive measures in Study 2. RESULTS: We show that people high in conspiracy mentality are likely to engage in non-normative prevention behaviours (Study 1), but are less willing to comply with extreme preventive behaviours that are government-driven (Study 2). However, we demonstrate that a perceived risk to oneself (risk of death) and a motivation to protect oneself can act as a suppressor: Conspiracy mentality is linked with an increase in the perception of risk to oneself, which, in turn, is associated with normative compliance. We also find that perceived risk of death explains the relationship between conspiracy mentality and non-normative prevention behaviours. CONCLUSIONS: Our studies showcase how people high in conspiracy theorizing may (dis)engage with prevention behaviours, but that perceived risk and motivation to protect oneself could increase these individuals' compliance.
