Recent Monte Carlo research has illustrated that the traditional method for assessing the construct-related validity of assessment center (AC) post-exercise dimension ratings (PEDRs), an application of confirmatory factor analysis (CFA) to a multitrait-multimethod matrix, produces inconsistent results [Lance, C. E., Woehr, D. J., & Meade, A. W.…

The analysis of convergent and discriminant validity is an integral part of the construct validation process. Models for analyzing the convergent and discriminant validity have typically been developed for cross-sectional data. There exist, however, only a few approaches for longitudinal data that can be applied for analyzing the construct…

This study explored the possibility of using the Multi-Trait Multi-Method (MTMM) approach of D. Campbell and D. Fiske (1959) to examine the educational ecology of classrooms. Using the MTMM approach, the study focuses on the extent to which multiple methods of inquiry (surveys, drawings, and videos) are valid indicators of classroom teaching and…
