During the COVID-19 pandemic decisions on physical distancing including decisions on wearing face masks in public may depend on a number of individual characteristics, representations of threats and the degree of personal responsibility for complying with the imposed requirements.. This study on a Russian sample (N = 308) took placeduring April-May 2020. We used verbal tasks on social distancing to test the hypotheses that individual differences in empathy, implicit theories of emotions, the Dark Triad traits, rationality, and risk readiness predict decisions on whether or not to wear a mask. We developed five verbal tasks – situations where decisions on whether to wear a mask or not were made by choosing from several given reasons. Among the reasons for wearing a mask, Care for Self was chosen by 46% of participants who received this as a reason, the Law-abidingness reason was chosen by 44%, and 31% selected Care for Others. Regarding the reasons for not wearing a mask, 16% of participants chose Autonomy for Oneself, 11% – Risk Underestimation and 5% – Autonomy for Others. Logistic regressions identified that empathy, rationality, and narcissism were significant predictors of a decision to wear a face mask, while risk readiness and psychopathy were predictors of a decision not to wear a mask. Implicit theories of emotions and problem-solving self-efficacy were significant predictors only for choices between the reasons for wearing a mask. Personality variables of empathy, rationality, risk readiness, and the Dark Triad traits influence decisions on adhering to physical distancing.
