Rong Ma Zexin Ma

J Health Commun 2021 Jun 17:1-10. Epub 2021 Jun 17.

Department of Communication, Journalism, and Public Relations, Oakland University, Rochester, Michigan, United States.

Drawing on the literature on social identity threat, this study examined how threatening ecigarette users' identities in a narrative impacts their perceived behavioral control regarding ecigarette use, and how this effect can be moderated by de-emphasizing the story character's user identity. In an experiment, current e-cigarette users (N = 395) read a conversation between the main character (an e-cigarette user) and their friend. Identity threat was manipulated using negative descriptions of e-cigarette users, and identity emphasis was manipulated through the main character's self-description. Read More
