Little research informs the use of the Extended Parallel Process Model (EPPM) of persuasion when threat and efficacy judgments are rendered for someone other than the message recipient. Nevertheless, a wide range of health promotion consists of influencing such judgments. Two studies examine the utility of using the EPPM in a context involving threats to others. Results show that the expected measurement models hold in this new context, and that an additive model is a stronger fit than a multiplicative one when considering how threat and efficacy combine to affect behavioral intentions but not when considering behavior. The study also examines the effects of a print intervention implemented with school employees in Michigan derived from the EPPM. The results are discussed in terms of their theoretical import and their application in this new context.
