Attention control groups play an important but controversial role in randomized controlled trials of behavioral interventions. The study by Pagoto et al. in this issue of Psychosomatic Medicine provides an informative example of some of the problems that attention control conditions can create in psychosomatic and behavioral medicine trials. This article discusses the reasons why these problems occur and provides some practical solutions. It also explains why controlling for attention is unnecessary and counterproductive in some behavioral trials.
注意控制组在行为干预的随机对照试验中起着重要但有争议的作用。帕戈托等人在本期《身心医学》中进行的研究为身心医学和行为医学试验中注意力控制条件可能产生的一些问题提供了一个信息丰富的例子。本文讨论了这些问题产生的原因，并提供了一些实际的解决方案。它还解释了为什么在某些行为试验中控制注意力是不必要的和适得其反的。
