Objective: 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.
