Abstract
Purpose: We evaluated the psychometric properties of the Korean version of the European Organization for Research and Treatment of Cancer high-dose chemotherapy specific quality of life questionnaire module (EORTC QLQ-HDC29) when implemented with Korean patients by conducting a multicenter, longitudinal study in three Korean hospitals. Methods: A total of 226 patients who scheduled to receive the HDC followed by hematopoietic stem cell transplantation (HSCT) were enrolled. The patients were asked to complete three questionnaires [the EORTC Core Questionnaire (QLQ-C30), QLQ-HDC29, and the Functional Assessment of Cancer Therapy-Bone Marrow Transplantation] at four points in time: before HSCT and 100, 180, and 365 days after HSCT. Standard validity and reliability analyses were performed. Results: Internal consistency of the QLQ-HDC29 was generally acceptable, as tested by Cronbach’s α, except for the scales body image and the inpatient issues. Cronbach’s α values for the Korean version of the QLQ-HDC29 were almost in accordance with results of the original version, except for the scales body image (lower to the original QLQ-HDC29, α = 0.73) and impact on family (higher to the original QLQ-HDC29, α = 0.52). Known-group comparison analyses showed significantly higher symptom burdens in patients with poor performance status or graft versus host disease (similar to the original QLQ-HDC29). The QLQ-HDC29 indicated good convergent and discriminant validity and showed responsiveness to changes in line with a clinical course over time after HSCT. Conclusions: The QLQ-HDC29 is generally reliable and adequate to assess QoL in Korean patients undergoing HDC followed by HSCT.
