对COSMIN-RoB清单中测量工具稳定性、测量误差和效标效度研究偏倚风险的清单解读

Interpretation of COSMIN risk of bias checklist in evaluating risk of bias of studies on reliability,measurement error and criteria validity of patient-reported outcome measures

COSMIN-RoB清单包括3个部分,共10个框目,分别用于评价内容效度研究、内部结构研究和其他测量属性研究的偏倚风险。其中其他测量属性研究关注PROMs整体的质量,包含稳定性、测量误差、效标效度、假设检验(构念效度)和反应度。在这5种测量属性中,稳定性、测量误差及效标效度在研究中使用最为广泛,因此,为使读者更好地理解和使用COSMIN-RoB清单评价这3种PROMs测量属性研究的偏倚风险,本文将结合具体实例进行解读。

The COSMIN-RoB checklist includes three sections with a total of 10 boxes,which is used to evaluate risk of bias of studies on content validity,internal structure,and other measurement properties.COSMIN classifies reliability,measurement error,criteria validity,hypothesis testing for construct validity,and responsiveness as other measurement properties,which primarily focus on the quality of the(sub)scale as a whole,rather than on the item level.Among the five measurement properties,reliability,measurement error and criteria validity are the most widely used in the studies.Therefore,this paper aims to interpret COSMIN-RoB checklist with examples to guide researchers to evaluate the risk of bias of the studies on reliability,measurement error and criteria validity of PROMs.
