Problems and Issues in Meta-Analysis.
George, Carrie A.
Single studies, by themselves, rarely explain the effect of treatments or interventions definitively in the social sciences. Researchers created meta-analysis in the 1970s to address this need. Since then, meta-analytic techniques have been used to support certain treatment modalities and to influence policymakers. Although these techniques originally showed great promise, criticisms of the method have developed. This paper explores the problems and issues associated with meta-analysis. These include problems of comparison of different independent variables and different variable constructs and problems that may arise from methodological flaws in some of the studies considered. Clerical errors, misinterpretation of effect sizes, and replicability issues are also concerns that need to be addressed. Missing data and the potential lack of statistical independence among effect size estimates are additional problems. The researcher is urged to take these issues into consideration when deciding whether or not to implement meta-analytic techniques. (Contains 21 references.) (SLD)
