Reanalyzed data from the Self-Description Questionnaire II (SDQII) from an earlier study of 376 gifted students, and a new study of 837 gifted students to explore alternative approaches to missing data and data normalization. Results strongly support the construct validity of responses to the SDQII by gifted adolescents. (SLD)

Results of a reanalysis of previously published data (B. M. Byrne, 1989) support the correlated uniqueness model, diagnostic tests of the validity of confirmatory factor analysis (CFA), multitrait multimethod (MTMM) solutions, inclusion of external validity in MTMM design, and application of factorial invariance to test stability of CFA-MTMM…

The present investigation extends the factor analytic approach pioneered by Fleishman (1964), incorporating subsequent developments in the application of confirmatory factor analysis and the physical fitness literature (e.g., an emphasis on maximum oxygen intake). More specifically, the ability of an a priori factor structure of physical fitness…

This investigation examines empirical support for the internal/external (I/E) frame of reference model which describes the relationships between verbal and math self-concepts, and between these academic self-concepts and verbal and math achievement. The empirical tests are based on all studies (n=6,010; ages 7 to 35 years) that have employed any…
