Houston, Wayne L., M.A., August, 1976, Interpersonal Communication Quantification of Source Credibility Variables for Oral Interpretation of Literature Director: William W. Wilmot This thesis attempted a two fold approach to the study of communication. It attempted to identify conceptual and operational definitions for the oral interpretation of literature and source credibility constructs, two constructs that have rarely been studied together. Measurement assumed equal importance with conceptualization; this study attempted to quantify source credibility variables for competitive oral interpretation of literature settings. Two independent data analysis techniques were employed, Statistical Package for the Social Sciences Factor Analysis, and TORSCA 2, a nonmetric multidimensional scaling program. Although convergent validity evidence was not one-to-one in nature between the factor analytic solutions and multidimensional scaling solution, striking similarities were apparent. In addition, free response criteria generated from the multidimensional scaling portion of the study, when analyzed, provided external support for convergence. Analysis of results indicate that a one dimensional solution for the multidimensional scaling portion and one emergent factor for the factor analytic solutions seem to be most appropriate indications of raters' perceptions of contest oral interpreters. This seems to indicate that the complexity of perceptual differentiation for the subjects rating contest oral interpreters was very low. Subjects tended to make wholistic rather than differentiated judgments. Implications were drawn, and a case was made for the objectification of the competitive oral interpretation of literature event.
