Several cancer centres/institutes from different European countries are involved in the study for the psychometric validation of the European Oncology Quality of Life Toolkit.

Partecipating centres have been enrolled through the Organisation of the European Cancer Institutes (OECI) network, covering most European countries.

OECI certified cancer centres work according to meaningful, relevant, and validated standards for quality in cancer research, education, and care.

The psychometric validation of EUonQoL-Kit is carried out in 46 institutions, covering 25 EU Member States, 6 associated countries and 1 third country, for an overall sample of about 4000 individuals.
