The project aims at comparing the computer-adaptive EORTC quality of life measures against other important patient-reported outcome (PRO) measures in the field that assess the same or similar constructs. The comparator instruments were selected for similarity of assessed domains, for being widely used in cancer research and for expected relevance in future cancer research. The projects includes a conceptual comparison of the PRO measures, the exploration of the possibility to link the EORTC measures to the comparator measures and the investigation of the relative validity of the EORTC measures and the comparator measures in known-group comparisons.
Protocol revisions, licensing for the various PRO questionnaires, set-up of electronic data collection platform.
