Testing Moderator Variable Hypotheses Meta-Analytically
提出一个三步程序，在元分析中检验调节变量假设，该方法结合了Hedges和Olkin的元分析框架与Hunter和Schmidt的心理测量学方法，通过校正研究层面的方法和统计伪差来检验效应大小的同质性和调节变量效应。
We propose and illustrate a three-step procedure for testing moderator variable hypotheses meta-analytically. The procedure is based on Hedges and Olkin's (1985) meta-analytic approach, yet it incorporates study-level corrections for methodological and statistical artifacts that are typically advocated and used within psychometric approaches to meta-analysis (e.g., Hunter & Schmidt, 1990). The threestep procedure entails: (a) correcting study-level effect size estimates for across-study variability due to methodological and statistical artifacts, (b) testing the overall homogeneity of study-level effect size estimates after the artifactual sources of variance have been removed, and (c) testing the effects of hypothesized moderator variables.
