• 6,000+ COAs described

    Choose the appropriate COAs for your research or practice

The success of patient-centered outcome research depends a great deal on the choice of appropriate Clinical Outcome Assessments (COAs).

COAs should be selected by the domains they measure as well as the populations and pathologies for which they were designed and validated. Such practical issues as the availability of different translations, copyrights, and access to instruments are also important considerations.


What makes PROQOLID™ stand out

Ensuring the information found in the PROQOLID database is not only accurate but also up to date, our staff works in close collaboration with the COA developers before publishing any information online.

To aid you in finding the questionnaire that is right for your study, Mapi Research Trust created the PROQOLID database. It has grown exponentially over the years and today 6,000+ COAs are comprehensively described, providing its users with two levels of access.
