Development of computerized adaptive testing (CAT) for the EORTC QLQ-C30 physical functioning dimension: General approach and initial results for physical functioning
Research output: Contribution to journal › Journal article › Research › peer-review
Computerized adaptive test (CAT) methods, based on item response theory (IRT), enable a patient-reported outcome instrument to be adapted to the individual patient while maintaining direct comparability of scores. The EORTC Quality of Life Group is developing a CAT version of the widely used EORTC QLQ-C30. We present the development and psychometric validation of the item pool for the first of the scales, physical functioning (PF).
