This study explores the dimensions of credibility in newspaper and television news and compares the dimensions of media credibility with those of interpersonal source credibility. Subjects, 401 Kent State University undergraduates, were given a 12-page questionnaire designed to assess attitudes toward the following: newspaper national and international news, television national and international news, television local and state news, and newspaper local and state news. Many significant differences were found in the credibility elements defined for newspapers and television. With regard to the relationship between media credibility and interpersonal source credibility, many similarities and some differences were found. Factors of media credibility appeared to vary according to the news concepts presented and the sample group considered. In the evaluation of both newspaper and television news, subjects considered personality aspects involved in the news as a major criterion. A multidimensional approach is recommended for further study of this topic. (Author/KS)
