Abstract

Study Design: Prospective study. Purpose: We aimed to validate the Persian version of the modified Oswestry disability questionnaire (MODQ) in patients with low back pain. Overview of Literature: Modified Oswestry low back pain disability questionnaire is a well-known condition-specific outcome measure that helps quantify disability in patients with lumbar syndromes. Methods: To test the validity in a pilot study, the Persian MODQ was administered to 25 individuals with low back pain. We then enrolled 200 consecutive patients with low back pain to fill the Persian MODQ as well as the short form 36 (SF-36) questionnaire. Convergent validity of the MODQ was tested using the Spearman's correlation coefficient between the MODQ and SF-36 subscales. Intraclass correlation coefficient (ICC) and Cronbach's a coefficient were measured to test the reliability between test and retest and internal consistency of all items, respectively. Results: ICC for individual items ranged from 0.43 to 0.80 showing good reliability and reproducibility of each individual item. Cronbach's a coefficient was 0.69 showing good internal consistency across all 10 items of the Persian MODQ. Total MODQ score showed moderate to strong correlation with the eight subscales and the two domains of the SF-36. The highest correlation was between the MODQ and the physical functioning subscale of the SF-36 (r =-0.54, p < 0.001) and the physical component domain of the SF-36 (r =-0.55, p < 0.001) showing that MODQ is measuring what it is supposed to measure in terms of disability and physical function. Conclusions: Persian version of the MODQ is a valid and reliable tool for the assessment of the disability following low back pain. © 2016 by Korean Society of Spine Surgery.
