Research on the direct-product model is extended by deriving hierarchically nested models for explicitly testing the patterns of method and trait factors and through formal tests developed for the pattern of communalities. These procedures are illustrated, and use of the MUTMUM computer program is discussed. (SLD)

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…

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…
