The Self-Description Questionnaire III (SDQ III) was designed to measure 13 factors of self-concept. The reliabilities of the factors were high, and correlations among them were low. Academic achievement measures in language and mathematics were correlated with self-concepts in the same areas but not with other self-concept factors. (Author/DWH)

The validity of a comparison of mean test scores for two groups and of a longitudinal comparison of means within each group is assessed. Using LISREL, factor analyses are used to test the hypotheses of similar factor patterns, equal units of measurement, and equal measurement accuracy between groups and across time. (Author/DWH)

Factor analyses of the Kaufman Assessment Battery for Children (K-ABC) were performed on separate groups of Anglo (n=100) and Mexican-American (n=100) fifth-grade children to determine the comparability of underlying structures and to examine the existence of possible bias in construct validity of the K-ABC for each group.

Results of the investigation suggest that the facet-factorial approach can be an effective technique for the construction of rating scales to measure complex behavior such as music performance. (Author)

The relationship of multiple-choice and free-response items on the College Board's Advanced Placement Computer Science Examination was studied using confirmatory factor analysis. Results with 2 samples of 1,000 high school students suggested that the most parsimonious fit was achieved using a single factor. Implications for construct validity are…
