A study was conducted to examine the relationship between the belief system structure (dogmatism) of principals and media specialists and their role expectations for the media specialist, and whether agreement by principals and media specialists on the role of the media specialist was related to the similarity of their belief system orientations. Thirty-one pairs of principals and media specialists from public high schools responded to the Short Form Dogmatism Scale and a Rank Ordering Questionnaire assessing the relative importance of selected media specialist tasks. Results indicated there were main effect differences between principals and media specialists for instructional design and utilization, and between open and closed-minded respondents for awareness services. Similarity of dogmatism scores of principal-media specialist pairs was related to similarity of rank ordering of media specialist tasks. It appears that principals and media specialists tend to rank the more traditional media specialist tasks as more important than the more progressive media specialist tasks, although media specialists tended to be somewhat more progressive. In addition, it appears that dogmatism, as a personality variable, may be a factor in influencing a professional relationship, especially during initial contacts. (Author/CMV)
