| Abstract |
Background: There are two questionnaires available for the diagnosis of restless legs syndrome (RLS); Paradigm of questions for epidemiology studies of RLS, and the Johns Hopkins telephone diagnostic interview form (JHTDIF) for the RLS. The purpose of this study was to validate the Korean version of these questionnaires and to evaluate their usefulness.
Methods: We developed the Korean version of the RLS questionnaire proposed for epidemiology and the JHTDIF for the RLS. A total of 96 participants (34 RLS, 62 non-RLS) were included in this study. These questionnaires were used for the interview with a retest approximately a month later. These results were compared with the clinical diagnosis. Kappa value, percent agreement, and Cronbach’s Alpha were calculated for each question and validity coefficients were estimated from these statistics.
Results: The Kappa values of the Korean version in the RLS questionnaire for epidemiology studies were 0.794 for the 1st test, and 0.745 for the retest. The Kappa values of the Korean version in the Johns Hopkins telephone diagnostic interview for the RLS were 0.883 for the 1st test, and 0.834 for the retest. The two questionnaires proved to have high Kappa values and validity coefficients. Two forms were found to have a high test-retest reliability (r=0.927, 0.958).
Conclusions: The Korean version of the RLS questionnaire proposed for epidemiology and the JHTDIF for the RLS could be a reliable and valid tool for screening patients with RLS in Korea. KeyWords:Restless legs syndrome, Sleep disorder, Questionnaires |
