Abstract
Grounded in social cognitive theory, this research examines the effects of reality entertainment programming and embedded commercials on viewers' perceived motivations and efficacy to exercise and consume a healthy diet as well as on food preference. In a 3 (program type) × 2 (advertisement type) study design, 253 female undergraduates were randomly assigned to watch an episode of a health-oriented reality program, a non-heath-oriented reality program, or a health-themed sitcom in which commercials for either healthy or unhealthy foods were embedded. Results indicated that perceived realism of the health-oriented reality program generated greater confidence to eat more healthily and exercise, as well as greater motivation to exercise. Additionally, program viewing differentially affected motivations to eat healthily and to exercise, but only when type of advertisement (high vs. low calorie food ads) was taken into consideration. Finally, women who watched the health-oriented reality program were more likely to choose a healthy snack at the conclusion of the experiment than those exposed to other programs, thus supporting the assertion that reality programming may potentiate positive health behaviors. The role of the embedded advertisements in altering the interpretation and health impact of the programming is also discussed.
