A Factor Analytic Study of the Wisconsin Tests of Testimony and Reasoning Assessment (WISTTRA). Report from Concepts in Verbal Argument Project.
Harris, Margaret L.
Speech specialists have developed a taxonomy of concepts and abilities related to verbal argument as used in ordinary discourse. This study represents one possible step in the validation of that taxonomy: an evaluation of the Wisconsin Tests of Testimony and Reasoning Assessment (WISTTRA) and the underlying abilities or dimensions measured by them. It is, thus, a study of the construct validity of the concepts and abilities of verbal argument defined by Allen, Feezel, and Kauffeld (See ED 016 658). Data from over 1200 students were subjected to reliability estimation and factor analysis. Both derived orthogonal and derived oblique factor solutions were obtained for each of three initial factor methods. The major conclusion is that the tests based upon the taxonomy have construct validity at a particular level of specificity. This level is the specific internal (accept and reject) and external (consistency, recency, and proximity) tests used in assessing testimony and the four argument components for reasoning.
