 In September 2008, the NCI awarded a contract N02-PC-85002-29; PI: Basch; Co-I: Hay to support the development of an electronic-based and psychometrically robust patient-reported outcomes version of the symptom-related AEs listed in the CTCAE in an effort to improve the accuracy and precision of grading of this class of AEs. To achieve this goal, we will conduct cognitive interviews with 77 newly-developed PRO items that will subsequently be subjected to psychometric analysis, usability testing, and feasibility testing in a range of treatment settings among diverse groups of patients.
