| Abstract: | This study evaluated the effect of a persuasive message derived from a revised version of the theory of reasoned action on the performance of testicular self-examination (TSE). Subjects (114 male college students) were randomly assigned to listen to a taped persuasive message challenging unfavorable outcome beliefs (as suggested by the theory of reasoned action), a message on testicular cancer information, or no message. All subjects then completed a questionnaire operationalizing the components of the theory of reasoned action (revised to incorporate self-efficacy). As predicted, there was a significant relationship between exposure to the persuasive message and self-reported TSE performance (χ2(2) = 15.66, p < .0001). Sixty-three (71.23%) of the subjects contacted at a 4-week follow-up reported performing the exam. Of those, 44.23% had heard the theory-based message, 36.54% had heard the informational message, and 19.23% had not been exposed to a message. A path analysis of the relationships among components of the theoretical model provided partial support for the hypothesized causal pathways between message exposure and TSE intention and behavior. |
