This study investigates the relationships among factor correlations, inter-item correlations, and the reliability estimates of subscores, providing a guideline with respect to psychometric properties of useful subscores. In addition, it compares subscore estimation methods with respect to reliability and distinctness. The subscore estimation…

Used aggregate ratings of teacher behavior as data for a multitrait-multimethod validity analysis. Scaled ratings using Rasch latent trait scaling model and traditional scaling techniques. Compared Rasch-scaled multitrait-multimethod matrix to the traditionally scaled multitrait-multimethod matrix. Results showed Rasch scaling resulted in higher…

This study assessed the construct validity of a cognitive structure interpretation of multidimensional scaling solutions of concept similarity data. Using high school subjects, convergent validity was assessed through correspondence of scaling solutions of three similarity rating tasks; word association, similarity judgment, and semantic…
