title: Cultural adaptation of a compliance questionnaire for patients with rheumatoid arthritis to a Korean version.
abstract: OBJECTIVE
  The Compliance Questionnaire-Rheumatology (CQR) is a validated scale to evaluate patient compliance for anti-rheumatic medications. We developed a Korean version of the CQR (KCQR) and confirmed its reliability and validity.
  
  
  METHODS
  We prepared the KCQR by translating and back-translating the original CQR with modifications to adapt it to Korean culture. Fifty Korean patients with rheumatoid arthritis (RA) were enrolled in this study. The test-retest reliability of the KCQR was evaluated at a 2-week interval using the intraclass correlation coefficient (ICC). The validity of the KCQR was assessed by identifying associations between KCQR scores and patient compliance, measured using pharmacy refill data.
  
  
  RESULTS
  The reliability of the KCQR was adequate, with an ICC of 0.71 for test-retest reliability. With respect to validity, the summed score of the weighted KCQR showed a significant correlation with pharmacy refill data (r² = 0.57) on multiple regression analysis.
  
  
  CONCLUSIONS
  Our results indicate that the KCQR is a reliable, valid instrument to evaluate compliance of Korean patients for RA medications.
