Objectives: COVID-19 has highlighted differences in our engagement in health prevention behaviors. The Health Belief Model (HBM), personality traits (conscientiousness, extraversion, and neuroticism), and sociodemographic variables were used to evaluate social distancing during the first month of a state-mandated Stay At Home (SAH) order.Design: A web-based convenience sample of 645 Ohioans was surveyed. Hierarchical linear regression and mediation analysis were used to examine predictors of social distancing attitudes and behaviors and whether health beliefs mediated the relationship between personality and social distancing.Results: Most respondents agreed with and adhered to social distancing guidelines.HBM constructs were strong predictors of SAH attitudes, while personality accounted for little additional variance. Anxiety was indirectly related to overall social distancing attitudes and behavior through its relationship with health beliefs. However, violations of social distancing were best explained by situational factors (e.g., being an essential worker). Conclusion:The results demonstrate the power of components of the HBM to explain attitudes and behaviors regarding the SAH order beyond any contribution from personality. By examining the role of personality and health beliefs on social distancing attitudes and behaviors, this research will benefit public health nurses and others tasked with communicating and promoting preventative health behavior.
