Since 1995, we have been creating an international network of PRO experts, which now incluldes over 3,100 researchers. We have also been establishing privileged relationships with opinion leaders, such as Prof. Donald Patrick from the University of Washington at Seattle who spent a sabbatical year with us in Lyon, Dr John Ware, developer of the SF-36, Dr Albert Wu developer of the MOS HIV, and Prof. CRB Joyce, developer of the SEIQoL. Besides our internal resources and our own expertise, all those privileged relationships help provide quick and reliable information on health-related quality of life.

We have also established collaborative links with other organizations involved in this field such as the Australian Health Outcomes Collaboration (AHOC), the Medical Outcomes Trust (MOT), and the World Health Organization (WHO).
