单一被试实验与元分析技术

单一被试实验是特殊儿童心理与教育研究中的一种常用方法，但其外部效度往往受到质疑。运用元分析技术，能对大量单一被试实验研究结果进行定量综述，既可综合评价各研究的总效应，也能探讨、揭示出各类研究特征与相应研究结果的关系，这无疑为单一被试实验信度与效度的检验提供了更多的信息。本文结合国外一个较新的研究实例，对元分析技术的基本原理及分析步骤作简要介绍，并对单一被试实验与元分析技术的结合应用问题提出几点看法与建议。

The Single Subject Research and Meta-Analysis

The single subject research is one of the useful methods in the research of special children's psychology and education, but its external validity often receives challenges. Meta-analysis technology can be applied to quantitative summaries of the many study results using the single subject experimental design. Mate-analysis can not only evaluate the total study effects, but also explore and reveal the relationships of study characteristics and results. Therefore, Meta-analysis will provide more information than a few single subject researches. This paper gives a study example, introduces the basic theories and approaches of mate-analysis, and puts forward some options and suggestions about a combinative use of the single subject research and mate-analysis.
