COnsensus-based Standards for the selection of health Measurement INstruments

COSMIN is an initiative of an international multidisciplinary team of researchers with a background in epidemiology, psychometrics, medicine, qualitative research, and health care, who have expertise in the development and evaluation of outcome measurement instruments.


Mission statement

The mission of COSMIN is to improve the selection of outcome measurement instruments of health outcomes by developing and encouraging the use of transparent methodology and practical tools for selecting the most suitable outcome measurement instrument in research and clinical practice.

We aim to improve the quality of studies on measurement properties by developing methodology and practical tools for assessing measurement properties, and we call for standardization of outcomes and outcome measurement instruments by developing core outcome sets (COS).

The COSMIN standards are update and extended now and then. The most recent information
