Abstract

Background: Screening of psychosocial risk factors for chronic low back pain (LBP) is essential. The Orebro Musculoskeletal Pain Screening Questionnaire (OMPSQ) is one of the most recognized and widely used instruments for this purpose. This study aimed to translate the OMPSQ into Persian, to adapt it for Iranian culture, and to investigate its psychometric properties. Methods: Using a linguistic methodology, the OMPSQ was translated into Persian according to the World Health Organization guideline. A total of 106 patients with LBP participated in the study. Internal consistency and test-retest reliability were evaluated. Concurrent validity was estimated with Pearson’s correlation between the OMPSQ and short form health survey (SF-12), Hospital Anxiety and Depression Scale (HADS), and visual analog scale (VAS). Factor analysis was used to evaluate dimensionality. Results: The content validity index was 0.80. The instrument had a good test-retest reliability (intraclass correlation coefficient = 0.82) and internal consistency (Cronbach’s α =0.82). Factor analysis indicates that factorial structure of Persian version was similar to original questionnaire. There was a significant correlation (r = 0.252–0.639, P < 0.01) between VAS score and all the OMPSQ domains. Physical component summary of SF-12 was positively correlated with miscellaneous domain (r = 384, P < 0.05) and negatively correlated with psychology domain of OMPSQ (r = −0.364, P < 0.05). A significant correlation between total score and anxiety component of HADS and psychology domain of OMPSQ was found (r = 0.49, P < 0.01 and r = 0.442, P < 0.05, respectively). Correlations between the OMPSQ and SF-12 and HADS and VAS indicate acceptable concurrent validity. Conclusions: The Persian version of OMPSQ was as a valid and reliable instrument and also a good cross-cultural equivalent for original English version. © 2017 International Journal of Preventive Medicine.
