许多人认为标准化和随机对照试验是齐头并进的。在不同的地方尽可能让干预看起来一样被认为是最重要的。但这可能就是为什么一些社区干预效果不佳的原因。我们建议彻底改变大规模干预通常概念化的方式。这可以使干预措施对当地环境做出反应，并且可能更有效，同时仍然允许在受控设计中进行有意义的评估。关键在于超越系统的简单元素，拥抱复杂的系统功能和过程。
Many people think that standardisation and randomised controlled trials go hand in hand. Having an intervention look the same as possible in different places is thought to be paramount. But this may be why some community interventions have had weak effects. We propose a radical departure from the way large scale interventions are typically conceptualised. This could liberate interventions to be responsive to local context and potentially more effective while still allowing meaningful evaluation in controlled designs. The key lies in looking past the simple elements of a system to embrace complex system functions and processes.
