Abstract

Objectives: The aim of this study was to analyze the reliability of the Korean language version of the Research Diagnostic Criteria for Temporomandibular Disorders(RDC/TMD) axis II questionnaire among TMD patients. Methods: The Korean version of the RDC/TMD questionnaire was distributed to 154 TMD patients(31 men, 123 women) who visited Seoul National University Dental Hospital. The test-retest reliability was also assessed among the same subjects with a one- or two-week time interval. The subjects did not receive any form of therapy until the retest administration was completed. Results: The internal consistency reliability of pain intensity, disability score, jaw disability, and psychosocial status were 0.92, 0.94, 0.68, and 0.94, respectively using the Cronbach's alpha coefficient of the 1st test. Test-retest reliability coefficients of each items of the questionnaire ranged from 0.40 to 0.94 assessed with kappa value, and the intra-class correlation coefficient(ICC) for each subscale ranged from 0.81 to 0.93. Test-retest reliability coefficient of the graded chronic pain(GCP) scale was 0.63. Conclusions: The Korean language version of RDC/TMD axis II questionnaire demonstrated good reliability. It can be used as a valuable instrument for the analyses of the psychosocial aspects of the TMD patients in Korea.

한국어판 측두하악장애 연구진단기준(RDC/TMD) 설문지의 신뢰도를 분석하기 위하여 서울대학교 치과병원 구강내과에 내원한 154명의 턱관절장애 환자들(남자 31명, 여자 123명)에게 한국어판 RDC/TMD 설문지를 작성하게 하였다. 검사-재검사 신뢰도는 동일한 피검자에게 1주 내지 2주 간격으로 같은 설문지를 작성토록 하였다. 설문지의 검사-재검사가 완료되기 전까지는 환자에게 어떠한 치료도 제공되지 않았다. 첫번째 검사로 본 통증강도(pain intensity), 장애점수(disability score), 악기능장애(jaw disability) 및 심리사회적 상태(psychosocial status)의 내적 일관성(internal consistency)의 신뢰도는 크론바흐-알파(Cronbach’s alpha) 계수로 각각 0.92, 0.94, 0.68, 0.94 였다. 검사-재검사 신뢰도의 각 설문항목별 상관계수는 0.40에서 0.94까지의 범위로 나타났으며, 각각의 세부 항목별 등급내 상관계수(intra-class correlation coefficient; ICC)는 0.81에서 0.93의 범위로 나타났다. 만성통증척도(Graded Chronic Pain)의 검사-재검사 신뢰도계수는 0.63이었다. 한국어판 RDC/TMD 설문지는 좋은 신뢰도를 보였으며, 한국인의 측두하악장애 환자들에서 심리사회적측면을 분석하는데 유용하게 사용될 수 있다.
