Abstract
Few past studies have used conjoint analysis to assess message design features and even fewer have looked at health issues. This research applies conjoint analysis to the quest to design motivational messages for African Americans at risk for diet-related adverse health outcomes (e.g., heart disease) in Kentucky. African American health in the state of Kentucky can benefit from a diet high in fruit and vegetable consumption, but little past research has been conducted with African American Kentuckians to explore the best message structure for communicating about increased fruit and vegetable consumption. This study reports on the outcome of the final phase of formative campaign research. We use an adaptive conjoint analysis to identify the most important elements of message design for this group of Kentucky residents. Results indicate that the message's source (i.e., the person delivering the message) is the most important design element for creating persuasive health messaging about fruit and vegetables for African Americans in Kentucky, followed by the stated benefit of eating more fruit and vegetables and the manner in which the behavior is described, respectively. To our knowledge, this study is the first to treat campaign message features as the subject of a conjoint analysis in order to identify which combination of features might be most motivating for a specific target audience. Recommendations for future health communication campaign application, as well as future research are discussed.
