Objective: We evaluated the psychometric properties of the Korean version of the European Organization for Research and Treatment of Cancer QLQ-PR25 when applied to Korean prostate cancer (PC) patients.
Methods: A total of 172 patients who underwent curative radical prostatectomy (RP) with or without adjuvant androgen deprivation therapy were asked to complete the Korean version of the EORTC QLQ-C30 and PR25 questionnaires 3 times (before and 3 and 6 months after RP). Psychometric evaluation of the questionnaire was conducted.
Results: Multitrait scaling analysis showed satisfactory construct validity in most scales except for bowel symptoms and hormonal treatment-related symptoms. Internal consistency tested by Cronbach's α coefficient met the 0.70 criterion for the urinary symptom, sexual activity and sexual functioning scales at the all 3 time points. Known-group comparison analyses showed better quality-of-life (QOL) scores in patients with higher performance status, and higher hormonal treatment-related symptom scores in patients on hormonal treatment. Responsiveness to changes was in line with clinical implications over time after RP.
Conclusions: Our results show that the EORTC QLQ-PR25 questionnaire has adequate levels in cross-cultural validity. The Korean version of the EORTC QLQ-PR25 is a generally reliable and robust instrument for the assessment of various QOL aspects that can be self-administered to Korean PC patients undergoing RP
