| Objective: The aim of this study was to translate the OMPQ into simplified Chinese version in Northern China and to evaluate its reliability and validity,so that we can attempt to promote the use of OMPQ and explore its feasibility as a supplementary tool to assess patients with low back pain in clinical practice.Subjects: 186 patients with acute or subacute low back pain who visited hospitals from July to Sep in 2019 were included and followed until Feb 2020.Method: We used Beaton cross-cultural translation guidelines to form the simplified Chinese version OMPQ(OMPQ-CHN).Participants were invited to fill in questionnaires when they first went to the hospital and were followed for 6 months.Based on the results,the reliability of OMPQ-CHN was evaluated using internal consistency and test-retest reliability,the validity of OMPQ-CHN was evaluated using content validity,concurrent validity and predictive validity.Results: The Cronbach’s α = 0.804,ICC = 0.833(95% CI: 0.683-0.915),I-CVI ranged from 0.86 to 1,S-CVI / Ave = 0.99.The correlation between the OMPQ-CHN and other questionnaires were r= 0.419,r = 0.551,r = 0.646 and r = 0.586 respectively.The AUC of predicting the pain,dysfunction and sick leave ranged from 0.714 to 0.810.Conclusion: 1)The OMPQ-CHN has high internal consistency and good testretest reliability;2)The OMPQ-CHN has satisfied content validity;3)There is moderate correlation between OMPQ-CHN,FABQ,RMDQ and VAS,and a good correlation between OMPQ-CHN and ODI;4)The OMPQ-CHN has moderate validity in predicting patients’ pain,dysfunction and sick leave after 6 months. |
