单一被试实验与元分析技术

The Single Subject Research and Meta-Analysis

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 。

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.
