Meta-Analysis of Factor Analyses: An Illustration Using the Buss-Durkee Hostility Inventory

Abstract
Among the many topics considered by meta-analysts, one that has received relatively little attention is the statistical integration of multivariate outcome data. This article focuses on a procedure proposed by Kaiser that has been used to integrate the results from different factor analyses. After giving a geometrical description of Kaiser's procedure, the authors illustrate its use with factor analytic studies of the Buss-Durkee Hostility Inventory. The results show that the seven subscales of the Buss-Durkee Hostility Inventory measure two dimensions of aggressiveness, one that can be called covert. The need for further development and application of multivariate data synthesis procedures is also discussed.
