随机对照试验(RCT)为使用心理干预的循证实践提供了关键支持。控制条件是去除随机对照试验中不需要的变量影响的主要方法。在控制条件的设计和构造方面几乎没有一致性或一致性。由于控制条件具有可变的影响,随机对照试验的结果可能取决于控制条件的选择,因为实验干预。本文的目的是提出一个框架,这些试验的控制条件的选择和设计。现代随机对照试验方法所产生的内部效度的威胁进行审查和重新考虑。检查几类控制条件的优点和缺点,包括实验控制下的,临床服务提供者控制下的,和无治疗控制。在选择控制条件的考虑进行了讨论,并提出了几项建议。本文的目的是开始定义的原则,控制条件可以选择或开发的方式,可以帮助调查人员和赠款审查。版权所有(C)2009 S.

The randomized controlled trial (RCT) provides critical support for evidence-based practice using psychological interventions. The control condition is the principal method of removing the influence of unwanted variables in RCTs. There is little agreement or consistency in the design and construction of control conditions. Because control conditions have variable effects, the results of RCTs can depend as much on control condition selection as on the experimental intervention. The aim of this paper is to present a framework for the selection and design of control conditions for these trials. Threats to internal validity arising from modern RCT methodology are reviewed and reconsidered. The strengths and weaknesses of several categories of control conditions are examined, including the ones that are under experimental control, the ones that are under the control of clinical service providers, and no-treatment controls. Considerations in the selection of control conditions are discussed and several recommendations are proposed. The aim of this paper is to begin to define principles by which control conditions can be selected or developed in a manner that can assist both investigators and grant reviewers.
