Examining theoretical models through research synthesis. The benefits of model-driven meta-analysis

Quantitative research synthesis methods can be used to examine theoretical models for substantive research questions. Model-driven syntheses can address more complex questions than have typically been addressed in quantitative reviews in a more systematic and organized manner than in a traditional narrative review. A rationale and set of objectives for syntheses involving models are reviewed. The author describes how to incorporate models into each stage of a review, outlining problems and limitations that may arise at each stage. Examples from several model-driven syntheses illustrate the points made in the article.
