is a structured tool developed by OMERACT to assess whether methodological standards have been properly followed in the development of Core Outcome Sets (COS) and measurement instruments. It helps working groups systematically evaluate the adequacy of evidence, the quality of consensus processes, and the transparency of reporting—ensuring that outcomes and instruments meet high scientific and stakeholder-driven standards.
Example
When a working group completes its instrument selection process for a new pain measurement tool, it uses the Good Methods Checklist to verify that all OMERACT standards—such as evidence review, stakeholder engagement, consensus methods, and transparent reporting—have been met before submitting the tool for endorsement.
