The objectives of this study were a to evaluate the Navys six health promotion videotapes in terms of changes in knowledge, self-efficacy, behavioral intentions, and self-report of behavior, b to determine the effects of a pre- and postviewing discussion, and c to report subjective viewer ratings for each of the six videotapes. 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. A repeated measures, split-plot factorial design was employed to evaluate the six videotapes. A pre- and posttest questionnaire was used to assess changes in knowledge, self- efficacy, behavioral intent, and self-report of behavior in 299 active duty, Navy personnel from four shore commands and three ships. In addition, a short survey was administered after the viewing of each videotape to obtain viewer ratings and comments. Analyses of the knowledge scores indicated no significant differences between groups experimental, control across time pretest, posttest for five of the six videotapes. The one videotape that produced significant knowledge effects was the back injury prevention videotape. Separate analyses of the self-efficacy measures, behavioral intentions, self-report of behavior, and of the pre- and postviewing discussion did not reveal any significant results. Additional analyses on high risk subgroups were also reported. Among the viewer ratings, the back injury prevention videotape was rated higher than all of the other videotapes on all seven of the rating items.
