Abstract
This presentation focuses on examining and interpreting effect size heterogeneity in meta-analysis findings, and methods of incorporating heterogeneity in the two approaches of combining meta-analysis and structural equation modeling. We first review the various measures of effect sizes in organization sciences and how meta-analyses report information about effect size heterogeneity. We then compare and contrast two approaches that test structural models based on meta-analytically derived correlations. Based on recent research (Cheung, in press; Yu et al., 2016), we show how heterogeneity can be considered in these two approaches. Recommendations are provided for researchers to better use the rich information of effect size heterogeneity when they evaluate primary studies and/or conducting meta-analyses.
