Although protective behaviours can reduce the spread of COVID-19, strategies are required to motivate PwO to engage in these behaviours. Targeted messages can be used to encourage adherence to protective behaviours; however, careful consideration is needed to avoid worsen feelings of weight stigma. The Extended Parallel Process Model was applied to explore perceptions of COVID-19 and protective behaviours, and the effects of targeted messages on motivation among PwO. Participants (N=76) completed an online survey and received a targeted COVID-19 message. Adherence to protective behaviours was significantly correlated with response efficacy, self-efficacy, attitudes, and intentions. Following message exposure, feelings of weight stigma moderated the relationship between attitudes and protective behaviours.
