随机对照试验的价值仍然存在争议。[1]虽然这些试验的一些最早的例子可以在行为和心理社会研究中找到，但这不是一个容易采用随机对照试验来评估干预措施的领域。2最近的两个发展加剧了关于随机对照试验作用的辩论-迫切需要找到有效的艾滋病毒行为干预措施3 4和循证医学的进步，这是将随机对照试验从临床试验转移到健康促进等领域。本文认为，与临床医学相比，在行为领域的随机对照试验的优点和局限性，并询问如何这些试验可以成功地应用于评估行为干预。
The value of the randomised controlled trial still generates debate. 1 Although some of the earliest examples of these trials can be found in behavioural and psychosocial research, this is not an area that has adopted readily the randomised controlled trial to assess interventions. 2 Two recent developments have intensified debate about the role of randomised controlled trials—the urgent need to find effective behavioural interventions against HIV 3 4 and the advance of evidence based medicine, which is moving the randomised controlled trial beyond clinical trials into areas such as health promotion. This article considers the merits and limitations of randomised controlled trials in the behavioural area compared with clinical medicine, and asks how these trials can be applied successfully to assess behavioural interventions.
