Extent to which findings derived from 4 approaches to multimethod multitrait analyses (MTMM) were consistent in providing estimates of construct validity related to measurement of 4 dimensions of perceived competence across 4 maximally dissimilar rating methods was determined using sample of 158 eleventh graders in Canada. Four MTMM approaches…

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. (SLD)

Self/other agreement between self-concept ratings by the individual and self-concepts inferred by significant others is of theoretical and practical importance, but the review by J. S. Shrauger and T. J. Schoeneman (1979) found no evidence for such agreement. In the present investigation, the Self Description Questionnaire III (SDQIII) was…

The construct validity of a multidimensional adolescent self-concept was estimated separately for males and females, and the results were compared across gender. The application of four multitrait-multimethod (MTMM) approaches to estimating construct validity was demonstrated, and the scope and consistency of the findings derived from each were…
