Abstract
Purpose:To cross-culturally adapt and test the psychometric properties of the CoreOutcome Measures Index for the back (COMI-back) for the Arabic language in Egyptian patients with non-specific low back pain (LBP).Methods: COMI-back was translated and cross-culturally adapted into Arabic according to standard guidelines. Its construct validity was assessed in 85 patients with chronic LBP (mean (± SD) age, 41.1 (±10.4)years)who completed a booklet of questionnaires including the Arabic versions of COMI-back, Roland Morris Disability Questionnaire, Oswestry Disability Index, the Short Form Health Survey 36, and the Visual Analogue Scale for back pain. Test-retest reliability was assessed in 52 participants who completed the booklet again within 7 days. Results: Floor effects (worst status; 1.2-10.6%) and ceiling effects (best status; 1.2-11.8%) for COMI-back were acceptable, except for symptom-specific well-being (18.8%, floor), leg pain (23.5%, ceiling), and work disability (31.8%, ceiling). The COMI itemscores correlated with those of the reference questionnaires (u=0.45 to 0.88), except for the COMI symptom-specific well-being (u=0.16 - 0.17) and quality of life (u=0.38).The intra-class correlation coefficient for the summary score was 0.90, whereas that of the individual items ranged from 0.71 to 0.92. The standard error of measurement and minimal detectable change for the summary score were 0.51 and 1.41 points, respectively.Conclusion: The Arabic version of COMI-back represents a valid and reliable instrument for use in Arabic-speaking patients with non-specific LBP
