Dimension And Exercise Variance In Assessment Center Scores: A Large-Scale Evaluation Of Multitrait-Multimethod Studies, Filip Lievens, James M. Conway

Research Collection Lee Kong Chian School Of Business

This study addresses 3 questions regarding assessment center construct validity: (a) Are assessment center ratings best thought of is reflecting dimension constructs (dimension model). exercises (exercise model). or a combination? (b) To what extent do dimensions or exercises account for variance? (c) Which design characteristics increase dimension variance? To this end, a large set of multitrait-multimethod studies (N = 34) were analyzed, showing that assessment center ratings were best represented (i.e., in terms of fit and admissible solutions) by a model with correlated dimensions and exercises specified a correlated uniquenesses. In this model, dimension variance equals exercise variance. Significantly more …
