Shoulder pain constitutes an average of 16% of all musculoskeletal complaints1, and is the second most common musculoskeletal disorder in the primary care setting2. It also reports an annual incidence of fifteen new episodes per 1,000 patients observed in the primary care setting3. The Simple Shoulder Test (SST) is a simple and short patient-reported outcome measuring functional limitations of the affected shoulder in patients with shoulder dysfunction. Although it is widely used in different clinical cultures, a literature review to date revealed that the SST has not been translated and validated yet in the Arabic language. To cross-culturally adapt an Arabic version of the SST developed for the Emiratis population through a structured process to formulate an initial version of the SST-UAE Arabic version to pre-test the initial Arabic version on a group of UAE patients, to formulate the final Arabic version and finally, to assess its reliability and construct validity. A cross-sectional observational design. The process of cross-cultural adaptation was done in accordance with previously published guidelines of cross-cultural adaptation17. Sixty-one Emirates participants with shoulder pain were involved and completed the final Arabic SST version on two occasions to assess test-retest reliability and internal consistency. All participants completed the Arabic SST version, Visual Analogue Scale (VAS), and Arabic Shoulder Pain and Disability Index (SPADI). Test-retest reliability was assessed with intraclass correlation coefficient (ICC), internal consistency was determined using Cronbach's alpha and construct validity was tested by Spearman rank coefficients. The Arabic SST showed a high level of test-retest reliability (ICC of 0.95) at baseline and after 48 hours (-1.9), Cronbach's alpha was 0.97. Results also revealed a moderate positive correlation with VAS r = 0.43 (p ≤ 0.01), and a strong positive correlation between the Arabic–UAE SST and Arabic SPADI r = 0.79 (p ≤ 0.01). The A
