Testing the Effects of the Addition of Videos to a Website Promoting Environmental Breast Cancer Risk Reduction Practices: Are Videos Worth It?

摘要

Searching for ways to reach wider audiences in more comprehensible ways, health promotion agencies might add videos to their current web offerings. While potentially costly and time consuming to create, the effect of these videos on websites has not received much attention. This study translated research about the potential breast cancer risk for young girls associated with the household chemical perfluorooctanoic acid (PFOA) into two websites in which mothers with young daughters were randomly assigned to view (website with videos vs. website without videos). Results revealed that participants in the video condition found the advocated risk protective behaviors easier to perform and stated they were more likely to perform them than those in the non-video condition. Approximately 15 days after exposure, those in the video condition performed on average one more protective behavior than those in the non-video condition. Results also suggest that agencies' efforts should focus on creating one quality video to place on a homepage, as video views declined the deeper people navigated into the site. Behaviors advocated should also be ones that can have lasting impacts with one-time actions, as effects wore away over time. Additional strategies are discussed for health promoters seeking to create videos to add to their current websites.
