This study was a simple "before" and "after" attitude measurement experiment using an experimental group and a control group. The attitude measurements were made before and after the subjects in the experimental group were presented an informational briefing about the Air Force ROTC training program. Both the experimental group and the control group were subject to exposure to the Air Force mass communication advertising during the two-month study period. The results indicate that the increased knowledge gained by the experimental group through its exposure to the informational briefing caused a negative change of attitude within the group. However, the control group had no significant change of attitude during the study period even though more than 87 percent of those subjects were exposed to some form of Air Force advertising.

The problem of this study was to examine the community, stockholder, and consumer public relations of the Dr Pepper Company. The data were collected by an examination of the major areas in Dr Pepper's public relations department. Detailed questionnaires were used in interviewing the department's head, Harry Ellis, and his assistant, Jim Ball. Follow-up interviews clarified Ball's and Ellis's responses to the questionnaires. Chapter I introduces the thesis. Chapter II presents information about Dr Pepper's consumer relations, Chapter III presents data about stockholder relations, and Chapter IV presents information about community relations. Chapter V summarizes the study and makes conclusions and recommendations. Dr Pepper's overriding weakness was the lack of pre- or post-testing of its public relations efforts; and its strengths are that it has never been accused of doing misleading advertising and it labels its products so that the consumer knows its content. The recommendation was made to expand and departmentalize the public relations operation.
