This study examined the risk preventive responses of individuals, especially those who do not adhere to preventive measures (e.g. anti-maskers) for COVID-19, by integrating three dominant theories in risk and health communication. The complex causal relationship between motivational elements and individuals' preventive behavior adoption was studied using Fuzzy-Set Qualitative Comparative Analysis. With a survey (N = 372) of non-abiding populations, this study found generalizable and unique configurations of motivational elements. Different effects of key motivational variables from three theories were found with different demographic factors. Theoretical and practical implications were also discussed.
