Find the right tool

You can use our tools to improve the way you do research and the reliability of your results.
Start with the question that describes your situation:

I’m conducting a study on measurement properties

You are conducting a study on measurement properties, or you are reporting a study on measurement properties.

In one article, one or more measurement properties can be described. The evaluation of each measurement property, however, requires different design requirements and statistical analysis.

The tool that can help you to learn more about how to conduct studies on measurement properties is our book Measurement in Medicine or attend our course Clinimetrics, which is based on the book.

COSMIN Study Design Checklist

The COSMIN Study Design checklist is recommended for designing studies to evaluate measurement properties of PROMs.

About the Study Design checklist

COSMIN Reporting checklist

In collaboration with the University of Michigan, we are developing reporting guidelines for studies on measurement properties of PROMs.

Recommendations for sample sizes in reliability studies

To help you decide on the sample size and number of repeated measurements for your study on reliability or measurement error, we developed an app that provides tailed recommendations.

Assessing responsiveness

To help you understand the concept of responsiveness, and to show you an example of a study on responsiveness, have a look at our paper in the JCE.

Instruction to calculate MIC values

To help you calculating MIC values we developed an instruction note, which is available at the website clinimetrics.nl where all answers to the assignments of the book Measurement in Medicine can be found.

Performing a Delphi Study

Delphi studies can be used e.g. to develop an instrument or a COS, or to evaluate the content validity of an instrument. Arguments provided by the panelists are the key in such studies.

Two examples of Delphi studies
