Validity and reliability of the EQ-5D for cancer patients in Korea

Abstract

The Korean version of the EQ-5D may be a valid tool for assessing the health-related quality of life of patients with cancer. However, further research is needed to determine the reliability of the Korean EQ-5D over different time intervals and disease conditions.

Estimation of minimally important differences in the EQ-5D and SF-6D indices and their utility in stroke

“…A higher BI score indicates more independence in physical functioning. There was evidence on validity and reliability of EQ-5D, SF-36 and BI in Korean population [26-29]. …”

Systematic review recommends the European Organization for Research and Treatment of Cancer colorectal cancer–specific module for measuring quality of life in colorectal cancer patients

“…None of the HRQOL instruments have been evaluated and rated on all the nine measurement properties recommended by [29], and mCOH-QOL-Ostomy [37e39] were the instruments scored limited to strong positive evidence on all their measured properties without any negative or uncertain rating. Seven evaluated instruments were found to have at least one negative rating in any one of their reviewed measurement properties (version 3 of QLQ-C30 [27,29,30,65,66], Coping with CRC [58], Quality-Quantity Questionnaire [43], Mini-MAC Scale [49], SF-12 (version 2) [60], EQ-5D [72], and SF-6D [73]). …”

“…Thirty-two instruments were rated on this property with 11 rated as strong positive (version 1 of QLQ-C30 [28,64], version 3 of QLQ-C30 [5,27,30,65,66], QLQ-CR38 [21e27], QLQ-LMC21 [46,50], version 4 of FACT-G [23,27,69], FACT-C [23,27,33,34,55,59e61], FCSI-9 [35], FACIT-F [68], QLICP-CR [62], MSKCC Bowel Function [40,41], and EQ-5D [72]). …”

Acupuncture lowers blood pressure in mild hypertension patients: A randomized, controlled, assessor-blinded pilot trial

“…18 We used a Korean version of the EQ-5D that has been validated in the Korean population. 19,20 The questionnaire scores referred to the South Korean population-based preference weights for EQ-5D, each answer ranging from 0 to 1. The higher the total score, the better the quality of life.…”
