AbstractPurpose: The current study aimed to evaluate the internal consistency, test-retest reliability, and construct validity of the translated and adapted Arabic version of the Oxford shoulder score in patients with shoulder disorders.Methods: One hundred four patients (average age 45.9 ± 15.2 years; female 78.8%) with shoulder disorders, including impingement syndrome, rotator cuff disorder, osteoarthritis, and adhesive capsulitis, participated. The participants were asked to complete the adapted Arabic version of the Oxford shoulder score, shoulder pain and disability index, and the Arabic numeric pain rating scale. The participants were also asked to complete the second form of the Oxford shoulder score after one week to evaluate test-retest reliability. Two Arabic native speakers translated and adapted the Arabic version of the Oxford shoulder score as per given international guidelines.Results: All patients participated in the second assessment (response rate = 100%). Test-retest reliability and internal consistency of the Oxford shoulder score were high (intraclass correlation coefficient, 0.92; Cronbach's alpha coefficient, 0.91). A significant correlation between the Oxford shoulder score and the shoulder pain and disability index and Arabic numeric pain rating scale scores supported the construct validity of the scale (p < 0.001).Conclusions: The translated and adapted Arabic version of the Oxford shoulder score indicated adequate internal consistency, test-retest reliability and construct validity. The current study suggests that the Oxford shoulder score is a quick and easy outcome measure to assess pain and disability in patients with shoulder disorders.Implications for RehabilitationThe translated and adapted Arabic version of the Oxford shoulder score indicated adequate psychometric properties.The current study suggests that the Oxford shoulder score is a quick and easy outcome measure to assess pain and disability in patients with shoulder disorders.A significant correlation between the Oxford shoulder score and the Shoulder Pain and Disability Index and Arabic Numeric Pain Rating Scale scores supported the validity of the scale.
