Little is known about how psychological treatments work. Research on treatment-induced mediators of change may be of help in identifying potential causal mechanisms through which they operate. Outcome-focused randomised controlled trials provide an excellent opportunity for such work. However, certain conceptual and practical difficulties arise when studying psychological treatments, most especially deciding how best to conceptualise the treatment concerned and how to accommodate the fact that most psychological treatments are implemented flexibly. In this paper, these difficulties are discussed, and strategies and procedures for overcoming them are described.
关于心理治疗的作用机制，我们知之甚少。对治疗引起的变化中介因素的研究可能有助于识别其潜在的因果机制。以结果为导向的随机对照试验为这类研究提供了绝佳机会。然而，在研究心理治疗时会出现一些概念和实际困难，尤其是在确定如何最好地对相关治疗进行概念化，以及如何应对大多数心理治疗都是灵活实施这一事实方面。本文将讨论这些困难，并描述克服这些困难的策略和程序。
