在心理学研究中，旨在检测治疗效果的调解和缓和的分析越来越普遍。调解问题涉及产生治疗效果的过程。温和的问题涉及影响这种影响的大小的因素。虽然在不同参与者之间的待遇不同的情况下，分析程序已经制定得相当好，但在参与者之间的待遇不同的情况下，还没有制定审查调解和缓和的系统程序。作者提出了一种用普通最小二乘估计来分析这些问题的方法。
Analyses designed to detect mediation and moderation of treatment effects are increasingly prevalent in research in psychology. The mediation question concerns the processes that produce a treatment effect. The moderation question concerns factors that affect the magnitude of that effect. Although analytic procedures have been reasonably well worked out in the case in which the treatment varies between participants, no systematic procedures for examining mediation and moderation have been developed in the case in which the treatment varies within participants. The authors present an analytic approach to these issues using ordinary least squares estimation.
