The research literature of behavioral medicine, along with that of many other areas of scientific research, is experiencing dramatic growth. Many important research areas now have several or even dozens of research studies or clinical trials that address similar questions. These circumstances pose new problems in the appraisal, evaluation, and use of the collective body of research evidence on important questions. The use of quantitative procedures for combining research results has become important as a response to increasingly complex research literatures in biostatistics as well as in the social, behavioral, and physical sciences. Such procedures can make the synthesis of research findings more rigorous and potentially more valid, while providing feasible means for addressing ever larger and more complex collections of research findings.
