One determinant of risk perception and risk behaviour that is often overlooked is the degree to which we share psychological group membership with others. We outline, and summarize supporting evidence for, a theoretical model that articulates the role of shared group membership in attenuating health risk perception and increasing health risk behaviour. We emphasize the importance of attending to these processes in the context of the ongoing response to COVID-19 and conclude with three recommendations for how group processes can be harnessed to improve this response.This research was supported by Australian Research Council Discovery Early Career Research Award to the first author (DE160100592).10EnglishPublisher Copyright: © 2020 The British Psychological Societybehaviour changegroup processeshealth risk perceptionrisk takingtrust2020-07-0110.1111/bjso.12391http://www.scopus.com/inward/record.url?scp=85085602267&partnerID=8YFLogxK
