Predictors of seasonal influenza vaccination behaviour among nurses and implications for interventions to increase vaccination uptake: A cross-sectional survey

Willingness to Vaccinate Against COVID-19: The Role of Health Locus of Control and Conspiracy Theories

“…A recent study found the same pattern of the effects of HLOC on the vaccine intentions in British, but not in an Irish representative sample of the general adult population (Murphy et al, 2021). Our data are also consistent with the previous findings that powerful others HLOC is positively related to pro-vaccination attitudes in parents (Tinsley and Holtgrave, 1989;Aharon et al, 2018) and nurses (Zhang et al, 2012;Kan et al, 2018), even though no effect of HLOC was found with respect to influenza vaccination in the elderly (Nexøe et al, 1999). Given that powerful others HLOC correlates with trust in the physicians (Brincks et al, 2010) and concerns related to side-effects and safety of vaccines are the top reasons for vaccine hesitation and refusal (Neumann-Böhme et al, 2020), the link between HLOC and willingness to get vaccinated may be mediated by trust in the medical professionals.…”

“…However, such moderation was not found in our data. Noticing that the findings of negative associations between internal HLOC and the willingness to get vaccinated come from highly informed samples, considering the medialization of COVID-19 in our study and in Murphy et al (2021) and the medical background of the sample of Kan et al (2018), we propose that internal HLOC may increase the vaccination intentions in the lessinformed populations (perhaps increasing their awareness of the benefits or the mere existence of the vaccine) and decrease it in more informed ones (perhaps increasing the safety or efficacy concerns).…”

“…Interaction of two dimensions or interaction of an HLOC dimension with another construct may play a crucial role (Wallston, 2004;O'Hea et al, 2005). With respect to vaccination, the chance dimension correlated with the vaccination intentions negatively (Chapman and Coups, 1999) and powerful others (Zhang et al, 2012;Kan et al, 2018) and internal HLOC (HLOC_I) (Tinsley and Holtgrave, 1989;Chapman and Coups, 1999) positively, although Kan et al (2018) found opposite associations for the chance and internal HLOC, and the associations were not confirmed by Nexøe et al (1999). In a recent model of the attitudes of parents toward child vaccination, the internal and powerful others HLOC is linked with pro-vaccination and chance HLOC is linked with the anti-vaccination attitudes (Aharon et al, 2018).…”
