Behavior analysts have shown that a single-subject experimental design (SSED) is a useful tool for identifying the effectiveness of specific therapeutic techniques, whereas researchers outside applied behavior analysis (ABA) maintain that randomized placebo-controlled trials (RPCT) provide the most definite test of efficacy. In this paper the possible benefits that could result from supporting SSED studies by placebo control groups are discussed. However, the use of placebo groups in psychotherapy research arouses considerable controversy and many researchers argue against it. The main aim of this paper is to clarify theoretical and methodological problems associated with using placebo groups in psychotherapy research and to demonstrate that these problems can be solved if the assumptions on which they are based are reformulated. The article also discusses ethical issues about the use of placebo groups in research on the effectiveness of psychotherapy.
行为分析师表明，单受试者实验设计（SSED）是确定特定治疗技术有效性的有用工具，而应用行为分析（ABA）领域之外的研究人员则认为随机安慰剂对照试验（RPCT）能提供最确切的疗效测试。本文讨论了通过安慰剂对照组支持SSED研究可能带来的益处。然而，在心理治疗研究中使用安慰剂组引发了相当大的争议，许多研究人员对此表示反对。本文的主要目的是阐明心理治疗研究中使用安慰剂组相关的理论和方法问题，并表明如果重新阐述其基于的假设，这些问题是可以解决的。本文还讨论了在心理治疗有效性研究中使用安慰剂组的伦理问题。
