Conspiracy beliefs and attitudes toward COVID-19 vaccinations: A conceptual replication study in Finland

During the coronavirus pandemic, this study aimed to investigate the impact of conspiracy beliefs on Finnish attitudes toward vaccinations in general and COVID-19 vaccinations in particular. This study was a conceptual replication in Finland of a study by Pivetti et al. (2021). Some 529 Finnish participants responded to a self-report questionnaire during the partial lockdown in Finland in spring 2020. The hypothesized relationships between variables of interest were integrated in a serial multiple mediation model via structural equation modelling. Results showed that endorsing general conspiracy beliefs directly predicted (1) general attitudes toward vaccines and (2) COVID-19 conspiracy beliefs, and indirectly predicted (3) attitudes toward COVID-19 vaccines via the serial mediation of COVID-19 conspiracy beliefs and general attitudes toward vaccines. As for the antecedents of beliefs in conspiracy theories, political orientation and moral purity predicted beliefs in COVID-19 conspiracy theories. Trust in science was inversely related to general conspiracy beliefs. As for the consequences of conspiracy beliefs, COVID-19 conspiracy beliefs directly predicted support for governmental restrictions (negatively) and the perception of informational contamination (positively).
