COVID-19 precautionary behavior:  The Israeli case in the initial stage of the outbreak

Abstract Background: The lay public's behavioral responses during a virus spread, such as the COVID-19, play an important role in bringing the outbreak under control, and provide insights into development of risk communication messages to the public. Therefore, this study aimed to explore the association between knowledge about COVID-19, perceived susceptibility, emotional reactions and precautionary behavior among the Israeli lay public at the beginning of the COVID-19 outbreak.Method: A cross-sectional study was conducted among 1,407 participants, aged 18+.Participants completed measures of knowledge about COVID-19, perceived susceptibility, emotional reactions, precautionary behavior, and socio-demographic questionnaires. A hierarchical regression model was calculated with precautionary behavior as the dependent variable.Results: Findings indicated that precautionary behavior was higher for females, older participants, participants with higher levels of knowledge about COVID-19, and participants with greater negative emotional reactions. A negative curvilinear relationship was found between perceived susceptibility and precautionary behavior, so that the latter was highest for participants with moderate perceived susceptibility. All interaction terms were non-significant.Conclusions: Findings suggest that in order to enhance precautionary behavior in the initial stage of a virus outbreak, it is recommended to pay attention to the public’s knowledge about the virus, perceived susceptibility and emotional reactions. Although negative feelings about the virus may motivate preventive behavior, it is important to address these feelings.
