Evaluating Content Validity Using Multidimensional Scaling.
Sireci, Stephen G.
Multidimensional scaling (MDS) is a versatile technique for understanding the structure of multivariate data. Recent studies have applied MDS to the problem of evaluating content validity. This paper describes the importance of evaluating test content and the logic of using MDS to analyze data gathered from subject matter experts employed in content validation studies. Some recent applications of the procedure are reviewed, and illustrations of the results are presented. Suggestions for gathering content validity data and using MDS to analyze them are presented. (Contains 3 exhibits, 7 figures, and 24 references.) (Author/SLD)
