A meta-analytical integration of over 40 years of research on diversity training evaluation

Abstract

This meta-analysis of 260 independent samples assessed the effects of diversity training on 4 training outcomes over time and across characteristics of training context, design, and participants. Models from the training literature and psychological theory on diversity were used to generate theory-driven predictions. The results revealed an overall effect size (Hedges g) of .38 with the largest effect being for reactions to training and cognitive learning; smaller effects were found for behavioral and attitudinal/affective learning. Whereas the effects of diversity training on reactions and attitudinal/affective learning decayed over time, training effects on cognitive learning remained stab..
