Using the EPPM to Create and Evaluate the Effectiveness of Brochures to Increase the Use of Hearing Protection in Farmers and Landscape Workers

The extended parallel process model was employed to increase intentions to use on-the-job hearing protection among agricultural workers. Brochures were designed to increase perceptions of the threat of hearing loss and the efficacy of hearing protection to avert hearing loss. Brochures were presented to one half of the sample in each population (farmers and landscapers), and a questionnaire was administered assessing perceptions of threat, efficacy, and intentions. The other half of each sample completed the questionnaire, and then received brochures. Results indicated that farmers were initially high in threat and efficacy perceptions, but brochure exposure resulted in higher intentions to use hearing protection. Landscapers perceived higher threat, efficacy, and intentions after being presented with the brochure. Results are discussed in terms of future research and practical application.
