title: Interactive source and message effects in persuasion.
abstract: In this study, the influence of source and message frame on judgments of a public service announcement was examined. The participants in the experiment were 408 undergraduate students (126 men, 280 women, 2 unknown; M age=20.0, SD=2.5, range=18-23) of a Midwestern U.S. university. Message frame and source were manipulated in a between-subjects design. Two levels of the message frame were benefits of physical activity and costs of not engaging in regular physical activity; the source was a healthy or unhealthy individual. In the Healthy-source condition, "Kim Jones" set realistic goals for exercise and had a healthy lifestyle. Conversely, she was described as a sedentary individual who led an unhealthy lifestyle in the Sick-source condition. Results indicated that respondents in the conditions of gain frame-healthy source and cost frame-unhealthy source had more positive message judgment as compared to respondents in the conditions of gain frame-unhealthy source and cost frame-healthy source.
