Beyond emotions: Social cognitive predictors of COVID-19 vaccination intentions before and after vaccine roll-out.

This study examined how emotional and social-cognitive factors influence COVID-19 vaccination intentions during two key phases of the COVID-19 pandemic: before (April-June 2020) and after (January-February 2021) vaccination rollout. A total of 586 adults completed an online survey assessing beliefs about COVID-19, self-efficacy to adhere to protective behaviours, perceived stress, affect, psychological flexibility, and prosociality. Self-efficacy, prosociality, psychological flexibility and positive affect significantly declined after vaccination rollout.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Vacunas contra la COVID-19PsicologíaCOVID-19journal article10.1371/journal.pgph.0005668open accessPsicologíaVacunaciónInvestigación médicaGoal 3: Ensure healthy lives and promote well-being for all at all ages
