The Item Library is a database of items used in fully and partially validated EORTC quality of life questionnaires.
This tool has been created by the EORTC Quality of Life Group with the primary aim of being used during the development of new instruments.
Developers can access it to see how items were formulated in previous questionnaires and to reuse existing validated items and their translations.
Access to the Item Library can also be granted to academic and commercial users as a reference tool.
