Prior research has shown that the media play an agenda-setting role in political campaigns. A theoretical model was developed to investigate intrapersonal agenda's relationship with certain contingent factors. To test the model a study of the intrapersonal agenda (personally perceived salience of public issues) was then conducted as part of the 1988 presidential primary in Travis County, Texas. Four hundred and four registered voters (63% of those asked) completed interviews. Results demonstrated clear relationships among the political campaign, attention to newspaper campaign stories, and interpersonal discussion of the issues. Nonetheless, and contrary to earlier research, the findings showed no relationship between the personally perceived salience of all the issues and personal experience of them. In addition, the findings suggest that political affiliation, a factor that has not been given proper attention in previous agenda-setting studies, has some impact on intrapersonal agenda. The effects of political affiliation and personal experience on people's perceived salience of particular issues warrant further study.
