Trust in purpose, or trust and purpose?: Institutional trust influences the association between sense of purpose and COVID-19 vaccination

OBJECTIVE: Having a sense of purpose is associated with a wide variety of positive health outcomes, largely because purposeful individuals appear to take better care of themselves physically. However, work is limited regarding the role of purpose during health crises, such as the COVID-19 pandemic. METHOD: The current cross-sectional study investigated whether having a sense of purpose was associated COVID-19 vaccination rates and willingness, among a Swiss adult sample (n = 2328, Mean = 52.33 years), after accounting for participants' trust in different institutions. RESULTS: Results found that adults with higher levels of institutional trust were more likely to be vaccinated (rs range from 0.06 to 0.13) or were willing to do so (rs range from 0.22 to 0.39). Sense of purpose was associated modestly with greater vaccination status (r = 0.06). However, sense of purpose moderated several associations between trust and vaccination outcomes. Namely, sense of purpose was associated with greater likelihood for vaccination when individuals reported greater trust in university research centers and political institutions. CONCLUSION: Findings are discussed with respect to how they shape our understanding of purpose-health associations.
