COSMIN consensus-based standards for the selection of health status measurement instruments

Background

 

COSMIN is the acronym of COnsensus-based Standards for the selection of health status Measurement INstruments.

The COSMIN initiative aims to improve the selection of health measurement instruments. One of the aspects that should be taken into account when selecting a measurement instrument, are the measurement properties of the instruments. 

The studies in which these measurement properties are being evaluated should be of high methodological quality. High-quality studies of measurement properties are less prone to bias, and therefore, information about the measurement properties can be interpreted more soundly. As part of the COSMIN initiative, the aim of this project was to develop a checklist containing standards for appropriate design requirements and statistical methods, for evaluating the methodological quality of studies on the measurement properties of health measurement instruments. 

The COSMIN checklist can be used to evaluate the methodological quality of studies on measurement properties, for example in systematic reviews of measurement properties. In systematic reviews it is important to take the methodological quality of the selected studies into account. If the results of high quality studies differ from the results of low quality studies, this can be an indication of bias.
The COSMIN checklist can also be used as a guidance for designing or reporting a study on measurement properties.
Students can use the COSMIN checklist when learning about measurement properties.
Reviewers or editors of journals can use the COSMIN checklist to appraise the methodological quality of submitted studies on measurement properties and to check whether all important design aspects and statistical methods have been clearly reported.
