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.

Although the effect of religious belief on morally relevant behavior is well demonstrated, the reverse influence is less known. In this research, we examined the influence of morality on religious belief. In the first study, we used two samples from Turkey and the United States, and specifically tested the hypothesis that intergroup tolerance predicts a shift in meta-ethical views toward subjective morality, which in turn predicts decreased religious belief. To examine the relationship between intergroup tolerance and religiosity via subjective morality, a structural equation model (SEM) was run. SEM results yielded good fit to the data for both samples. Intergroup tolerance positively predicted subjective morality, and in turn, morality negatively predicted religiosity. The bias-corrected bootstrap analysis confirmed the mediation, indicating that the association between intergroup tolerance and religious belief was mediated via subjective morality. In Study 2, we probed for the causal relationship, and the results showed that manipulating intergroup tolerance increases subjective morality, but does not influence religiosity. Therefore, we found only partial evidence for our proposed model that tolerance causally influences subjective morality, but not religiosity. [ABSTRACT FROM AUTHOR]

The present study explored the relationship between grit, motivational beliefs and self-regulation among undergraduate students in the United States, the United Arab Emirates and Turkey. These factors place the responsibility of learning on the students, rather than the educational environment. As most studies continue to focus on Western, educated, industrialised, rich and democratic populations, the current investigation adds to the extant knowledge of non-cognitive factors in student learning by focusing on international samples in three different cultural contexts to determine if indeed these factors are related in diverse educational environments. Grit significantly predicted the other non-cognitive factors in each of the contexts studied. There was also a positive relationship between the two constructs representing motivational beliefs, namely, self-efficacy and task value, in each of the contexts studied. The relationship between the constructs, however, differed with respect to self-regulation behaviours in the three cultural contexts represented in the study. Possible explanations for these differences are discussed. [ABSTRACT FROM AUTHOR]

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; M age = 46.34 years, SD age = 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.
