Social norms campaigns to promote protective behaviours

The file correspond to the SPSS database used in an experimental pre-test-post-test longitudinal study about the effectiveness of a social norms campaign applied to COVID-19 protective behaviours among 141 university students during the pandemic. The study, published in Frontiers in Public Health (doi: 10.3389/fpubh.2024.1447335), concluded that social norms campaigns applied to COVID-19 protective behaviours are effective in times of pandemic (in adjusting the subjective social norms of individuals to the positive objective social norms of the group, and in increasing self-efficacy, protective behaviour intentions and protective behaviours of individuals) and might be extrapolated to other epidemic contexts.
