复合测量量表（CMS）在医学上越来越多地用于测量复杂的现象或概念，如疾病的风险和严重程度、身心功能和生活质量。为了研究目前用于构建CMS的方法，我们检查了最近发表在6个主要医学和流行病学期刊上的46项研究。测量水平、测量内容、结构效度和信度等重要的测量属性往往被忽视。统计方法，特别是多元统计方法经常被误用；很少进行模型相关性和假设的验证，以及避免过拟合的交叉验证。我们对CMS的构建和展示提出了建议，以帮助作者和研究者分别报告和选择测量仪器。
Composite measurement scales (CMS) are increasingly used in medicine to measure complex phenomena or concepts such as disease risk and severity, physical and psychological functioning and quality of life. To investigate the methodology currently used in the construction of CMS, we examined 46 studies recently published in six major medical and epidemiological journals. Important measurement properties such as measurement level, content and construct validity and reliability are often neglected. Statistical methods, particularly multivariate methods are frequently misused; verifications of model relevance and assumptions, and cross-validations to avoid overfitting are seldom performed. We propose recommendations for the construction and the presentation of CMS, to help authors and investigators to report and choose, respectively, measurement instruments for a complex phenomenon.
