Abstract
Under the threat of public health challenges such as the recent COVID-19 pandemic, individual citizens' active and cooperative participation in precautionary measures is crucial. Although non-compliance is recognized as a recurring problem, it remains unknown why some individuals tend to comply less than others and whether violations of preventive behaviors are observed consistently across different public health issues. To test our hypothesis that individuals would show consistent public health behavior transcending domains, we collected self-reports from two independent samples of participants (total N = 2983) on health risk beliefs and behavioral choices. Participants' responses were collected in regard to two separate yet closely related public health issues: smoking and the COVID-19 pandemic. Our data reveal that on average, individuals' beliefs and behaviors are consistent across different public health domains. In particular, smokers showed diminished compliance behaviors during the pandemic, which was mediated by their lower motives to protect public health. These results provide a psychological mechanism of how individuals' health risk behaviors are generalized across different public health domains that may explain why some individuals (here, current-smokers) are more prone to violate public health behaviors.
