The COSMIN checklist is a standardized tool for assessing the methodological quality of studies on measurement properties. It contains 9 boxes, each dealing with one measurement property, with 5-18 items per box about design aspects and statistical methods. Our aim was to develop a scoring system for the COSMIN checklist to calculate quality scores per measurement property when using the checklist in systematic reviews of measurement properties.
The scoring system was developed based on discussions among experts and testing of the scoring system on 46 articles from a systematic review. Four response options were defined for each COSMIN item (excellent, good, fair, and poor). A quality score per measurement property is obtained by taking the lowest rating of any item in a box ("worst score counts").
Specific criteria for excellent, good, fair, and poor quality for each COSMIN item are described. In defining the criteria, the "worst score counts" algorithm was taken into consideration. This means that only fatal flaws were defined as poor quality. The scores of the 46 articles show how the scoring system can be used to provide an overview of the methodological quality of studies included in a systematic review of measurement properties.
Based on experience in testing this scoring system on 46 articles, the COSMIN checklist with the proposed scoring system seems to be a useful tool for assessing the methodological quality of studies included in systematic reviews of measurement properties.
COSMIN 清单是一种评估测量特性研究方法学质量的标准化工具。它包含 9 个方框，每个方框处理一个测量特性，每个方框有 5-18 个关于设计方面和统计方法的项目。我们的目的是为 COSMIN 清单开发一个评分系统，以便在系统评价测量特性的研究中使用清单时计算每个测量特性的质量评分。
评分系统是基于专家讨论和对来自系统评价的 46 篇文章的评分系统测试而开发的。为每个 COSMIN 项目定义了四个响应选项（优秀、良好、中等和差）。每个测量特性的质量评分是通过采用方框中任何项目的最低评级（“最差得分计数”）来获得的。
为每个 COSMIN 项目描述了优秀、良好、中等和差质量的具体标准。在定义标准时，考虑了“最差得分计数”算法。这意味着只有致命缺陷才被定义为质量差。46 篇文章的得分展示了如何使用评分系统为系统评价中纳入的研究的方法学质量提供概述。
基于对 46 篇文章的测试经验，COSMIN 清单和提出的评分系统似乎是评估系统评价中纳入的研究方法学质量的有用工具。
