Applying the Extended Parallel Process Model to Climate Change Communication

Year: 2023

Presenter Name: Mikenna DeBruin

The Extended Parallel Process Model (i.e. the EPPM) is a health-risk model that combines appeals to fear and efficacy in order to promote a productive danger-control response in individuals. The EPPM has traditionally been applied to the fields of epidemiology and chronic illness; however, it has minimally been applied to climate change communication. Some climate change research examining fear appeals and efficacy appeals separately suggests that the EPPM may be a salient model for encouraging mitigation efforts towards climate change. Thus, I plan to expand the scope of the EPPM through a quantitative survey examining the impact of different EPPM message exposures on efficacy perceptions and behavioral intentions of individuals. These message exposures will vary along a positive-negative efficacy dichotomy and a high-low threat dichotomy. In January of 2023, survey participants in the United States will be reached through Prolific, and individuals will take the survey through Qualtrics. The data will be analyzed with the Statistical Package for the Social Sciences (SPSS) using a one-way multivariate analyses of variance (MANOVA).
