Comparing EORTC CAT

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

The project aims at comparing various questionnaires that are used for the assessment of quality of life, symptoms and problems in cancer patients. The comparisons will focus on questionnaire content and measurement precision.

Recruitment is ongoing and a first publication from the project has been submitted to the Executive Committee of the QLG.

Qualitative analyses for aim A and recruitment for aim B and C are ongoing.

Qualitative analyses for aim A and recruitment for aim B and C are ongoing. Quantitative analyses for aim B and C have started for the domains included in the samples SA1, SA3 and SA5. For support of the statistical analyses, a collaboration has been started with the Institute of Mathematics at the University of Innsbruck (Prof. Hell).

Recruitment for the three remaining parallel study samples (SA2, SA4, SA6).
