title: Cross-cultural adaptation of modified Oswestry Low Back Pain Disability Questionnaire to Thai and its reliability.
abstract: OBJECTIVE

  METHODS
  The process comprised of an initial forward translations from English to Thai, synthesis of the translations, back translation, and back translation approval. The approved version of Thai ODQ was then calculated for test-retest reliability. Forty patients with LBP, aged 40.1+/-10.7 years, were recruited into a test-retest reliability study.
  
  
  RESULTS
  The test-retest reliability, calculated by intraclass correlation coefficient, was assessed on two occasions separated by a time interval of 20-30 minutes. The values of test-retest reliability of items ranged from 0.80-1.00. The value of total score was 0.98.
  
  
  CONCLUSIONS
  This finding indicated good reliability of the Thai version modified ODQ.
