使用SPSS实现1:1倾向性评分匹配(PSM)

2017-10-19 医咖会医咖会

谈起临床研究，如何设立一个靠谱的对照，有时候成为整个研究成败的关键。对照设立的一个非常重要的原则就是可比性，简单说就是对照组除了研究因素外，其他的因素应该尽可能和试验组保持一致，这里就不得不提随机对照试验。众所周知，随机对照试验中研究对象是否接受干预是随机的，这就保证了组间其他混杂因素均衡可比。但是有些时候并不能实现随机化，比如说观察性研究。这时候倾向性评分匹配(propensity scor

谈起临床研究，如何设立一个靠谱的对照，有时候成为整个研究成败的关键。对照设立的一个非常重要的原则就是可比性，简单说就是对照组除了研究因素外，其他的因素应该尽可能和试验组保持一致，这里就不得不提随机对照试验。众所周知，随机对照试验中研究对象是否接受干预是随机的，这就保证了组间其他混杂因素均衡可比。但是有些时候并不能实现随机化，比如说观察性研究。这时候倾向性评分匹配(propensity score matching, PSM)可以有效降低混杂偏倚，并且在整个研究设计阶段，得到类似随机对照研究的效果。与常规匹配相比，倾向性评分匹配能考虑更多匹配因素，提高研究效率。这么“高大上”的倾向性评分匹配，是不是超级难学？错矣！今天就带大家轻松搞定1:1倾向性评分匹配。作为“稀罕”大招，并不是在所有版本的SPSS都可以实现倾向性评分匹配，仅在SPSS22及以上自带简易版PSM，对于其他版本或者想要体验完整版功能，就不得不去安装相应的软件（R软件、SPSS R插件、PS matching插件。。。超级难安装！那是需要运气和耐心的！）。本次使用SPSS 22为大家演示1:1倾向性评分匹配。一、问题与数据某
