title: The Japanese Orthopedic Association Back Pain Evaluation Questionnaire (JOABPEQ) for low back disorders: a validation study from Iran.
abstract: BACKGROUND
  Lumbar disc hernia (LDH) and lumbar spinal stenosis (LSS) are the most common diagnoses of low back and leg pain symptoms. The Japanese Orthopedic Association Back Pain Evaluation Questionnaire (JOABPEQ) is a measure of health-related quality of life in these patients. This study aimed to cross-culturally translate and validate the JOABPEQ in Iran.
  
  
  METHODS
  This was a prospective clinical validation study. The translation and cross-cultural adaptation of the original questionnaire was performed in accordance with published guidelines. A total of 103 patients with LDH or LSS were asked to respond to the questionnaire at two points in time: pre- and postoperative assessments (6 months follow-up). To test reliability, the internal consistency was assessed by Cronbach's alpha coefficient, and validity was assessed using convergent validity. Responsiveness to change was also assessed comparing patients' pre- and postoperative scores.
  
  
  RESULTS
  The Cronbach's alpha coefficients for the JOABPEQ at pre- and postoperative assessments ranged from 0.71 to 0.81, indicating a good internal consistency for the questionnaire. In addition, the correlation of each item with its hypothesized subscale of the JOABPEQ showed satisfactory results, suggesting that the items had a substantial association with the subscale representing the concept. Further analysis also indicated that the questionnaire was responsive to change (P < 0.0001).
  
  
  CONCLUSIONS
  In general, the Iranian version of JOABPEQ performed well, and the findings suggest that it is a reliable and valid measure of back pain evaluation among LDH and LCS patients.
