In confirmatory factor analysis (CFA), models exist that are admissible and demonstrably identified where the factor loading matrix from latent to manifest variables is of less than full column rank, even though other models are not identified. Implications for CFA are discussed. (SLD)

The multitrait-multimethod (MTMM) design of D. T. Campbell and D. W. Fiske (1959) is the most widely used paradigm for testing construct validity, but it continues to be plagued by problems associated with definition of terms, operationalizations of their guidelines, and analytic procedures used to test them. Using five diverse MTMM data sets,…

Items from two North American instruments, designed to measure students' evaluation of teaching effectiveness, were administered to university students in different countries. Most of the items were judged by the students to be appropriate and important. Statistical analysis showed strong support for both the convergent and divergent validity of…

Extending research on the Marsh/Shavelson model of self-concept, a set of 14 academic self-concept scales was related to school performance in 8 school subjects for a sample of 507 high school students. Correlations between matching areas of self-concept and achievement (0.45 to 0.70; mean r=.57) were substantial and larger than correlations…

Extensions of the confirmatory factor analysis approach to multitrait-multimethod data are demonstrated, and self-other agreement on multiple dimensions of self-concept are evaluated in 2 studies investigating the ability of significant others to infer multiple dimensions of self-concept for 151 Australian and 941 Canadian college students.
