Convergent and Discriminant Validity of Assessment Center Dimensions: A Conceptual and Empirical Reexamination of the Assessment Center Construct-Related Validity Paradox
指出评估中心评分在内容效度和效标效度良好时却缺乏聚合与区分效度这一悖论，并运用概化理论实证证明评估中心维度评分具有良好的聚合与区分效度，与以往研究结果不同。
This study notes that the lack of convergent and discriminant validity of assessment center ratings in the presence of content-related and criterion-related validity is paradoxical within a unitarian framework of validity. It also empirically demonstrates an application of generalizability theory to examining the convergent and discriminant validity of assessment center dimensional ratings. Generalizability analyses indicated that person, dimension, and person by dimension effects contribute large proportions of variance to the total variance in assessment center ratings. Alternately, exercise, rater, person by exercise, and dimension by exercise effects are shown to contribute little to the total variance. Correlational and confirmatory factor analyses results were consistent with the generalizability results. This provides strong evidence for the convergent and discriminant validity of the assessment center dimension ratings–a finding consistent with the conceptual underpinnings of the unitarian view of validity and inconsistent with previously reported results. Implications for future research and practice are discussed.
