Mitigating Identity Threat in Health Messaging: A Social Identity Complexity Perspective

ABSTRACT

Health messages aiming to reduce red meat consumption may threaten multiple social identities because people’s dietary choices are intertwined with personal, social, and cultural aspects of their lives. Leveraging social identity theory and the concept of social identity complexity, this experiment tested how identity-threatening messages affect people’s intention to reduce red meat consumption and how the effect of identity threat may be moderated by messages highlighting the relationships between multiple identities that define a person. Participants (N = 409) read messages that varied identity threat (i.e. the extent to which people feel devalued because of their membership in a social group) and identity complexity (i.e. the extent to which people perceive multiple identities as independent). The study found that identity-threatening messages decreased intentions to reduce red meat consumption when people perceived their dietary identity as overlapping with other identities, but increased the intentions when the dietary identity was seen as independent from other identities. Further, the effects of identity threat and complexity were limited to people with high (vs. low) levels of red meat consumption. We discuss the role of identity complexity in alleviating identity threat and increasing persuasion.
