本文提出了一种新的方法，用于对测试前-测试后设计的数据进行meta分析。通过这种方法，可以直接比较使用不同设计的研究的数据，而无需省略没有对照组的研究。该方法基于“标准化平均变化”测量，为研究中的每个样本计算，并涉及对标准化平均变化和标准化平均变化差异的分析。分析是用心理练习对运动技能发展的有效性的研究结果来说明的。
A new approach is presented for the meta‐analysis of data from pre‐test‐post‐test designs. With this approach, data from studies using different designs may be compared directly and studies without control groups need not be omitted. The approach is based on a ‘standardized mean‐change’ measure, computed for each sample within a study, and involves analysis of the standardized mean changes and differences in the standardized mean changes. Analyses are illustrated using results of studies of the effectiveness of mental practice on motor‐skill development.
