These new CAT measures are conceptualised to reflect the same constructs as the QLQ-C30 scales. Accordingly the Fatigue-CAT is intended to capture physical and general fatigue. Methods The EORTC approach to CAT development comprises four phases literature search operationalisation pre-testing and field testing . Phases I-III are described in detail in this paper. A literature search for fatigue items was performed in major medical databases. After refinement through several expert panels the remaining items were used as the basis for adapting items and or formulating new items fitting the EORTC item style. To obtain feedback from patients with cancer these English items were translated into Danish French German and Spanish and tested in the respective countries. Results Based on the literature search a list containing 588 items was generated. After a comprehensive item selection procedure focusing on content redundancy item clarity and item difficulty a list of 44 fatigue items was generated. Patient interviews n 52 resulted in 12 revisions of wording and translations. Discussion The item list developed in phases I-III will be further investigated within a field-testing phase IV to examine psychometric .
