The purpose of this research was to determine if viewing a videotape could be an effective method to promote healthful knowledge and behaviors among Navy personnel. The objectives of this study were to (a) evaluate six U.S. Navy health promotion videotapes in terms of changes in knowledge, self-efficacy, behavioral intentions, and self-reported behavior, and (b) determine the effects of a pre- and post-viewing discussion. A repeated measures, split-plot factorial design with experimental and control groups was employed to evaluate the six videotapes. A pre- and post-test questionnaire was used to assess changes in knowledge, self-efficacy, behavioral intent, and self-reported behavior in 299 active duty personnel. It was found that the back injury prevention videotape produced a significant increase in knowledge by group over time. However, the other five videotapes did not produce significant increases in knowledge, self-efficacy, behavioral intentions, or self-reported behavior. These findings indicate that the videotapes were not an effective means of changing health knowledge and behaviors among Navy personnel. The outcome of this study underscores the importance of formal evaluation of health education programs. In addition, it is suggested that the most viable approach to health behavior change likely will involve integration of health education along with other behavioral, regulatory, and technological interventions.
