Over 3,000 PRO questionnaires, either generic or specific, are available within our library. Out of these, more than 500 were translated by the MAPI Institute into over 145 languages. Other questionnaires were gathered from the literature or were received directly from their developer further to specific requests. Disease-specific questionnaires are classified by pathology and population, each folder containing as much structured information as possible such as a descriptive table on the questionnaire, a copy of the questionnaire in its original language, some of its translations, specific publications, conditions for use and dissemination. One third of the questionnaires are also available in electronic form. This unique collection complements the information provided in PROQOLID.

All the questionnaires and their translations can be consulted in-house.
