The effects of subjective and moral norms and PBC suggests that these should be viable targets for behavioral interventions aimed at promoting social distancing behavior based on the model. For example, messages promoting moral obligation (e.g., highlighting social responsibility for preventing transmission of the virus to vulnerable others through social distancing) and perceived control (e.g., demonstrating how to easily and successfully maintain appropriate social distance) may facilitate greater intention to socially distance. However, the intention–behavior relationship in the present study was relatively modest in size, particularly in the Australian sample, indicative of a substantive intention–behavior “gap” [15]. This suggests that interventions targeting change in intention determinants, such as moral norms and PBC, may have only small effects on social distancing behavior. It may be of value to explore how properties of intention may affect intention–behavior relations in the context of social distancing behavior [35]. Such properties may signal potential intervention strategies that may strengthen intention–behavior relations in conjunction with messaging targeting moral norms and PBC.
