Issues in Meta-Analytic Structural Equation Modeling

This chapter provides short overviews of unresolved issues in MASEM. The first part of this chapter describes software that can be used to conduct MASEM using TSSEM, the GLS-method and the univariate method. The metaSEM-package is very useful for MASEM. Analyses using this package are shown in the last two chapters of this book. The second issue is about the use of different fit-indices to evaluate the homogeneity of correlation matrices at Stage 1 of TSSEM. The third issue is about handling missing correlations in specific studies. The basic approach is to delete a variable that is associated with a missing correlation, but more efficient methods are possible. The last issue is about a recent adaptation to the existing MASEM approach that may have advantages for handling heterogeneity. The adaptation involves a Stage 2 analysis based on a multigroup model.
