Abstract
Version Two of the Kaiser Measures of Sampling Adequacy was derived for a typical six-concept Semantic Differential. The over-all indices indicated that both concept and total correlation matrices would lead to comparable decisions regarding the psychometric quality of the sample data sets. The individual measures, however, showed considerable variability for some scales, placing several in a range which would make them suspect psycho-metrically. It was recommended that the concept of psychometric adequacy be used in determining the efficacy of one's Semantic Differential data for factor analytic procedures.
