The Shanghai Elbow Dysfunction Score: Psychometric Properties, Reliability and Validity Study of the Turkish Version

Abstract

The Shanghai Elbow Dysfunction Score (SHEDS) is a self-reported assessment of post-traumatic elbow stiffness that measures elbow-related symptoms and elbow motion capacities. This study aimed to (1) translate and cross-culturally adapt the SHEDS into Turkish and (2) investigate the psychometric properties of the Turkish version in patients with post-traumatic elbow stiffness. The psychometric properties of the Turkish version of the SHEDS (SHEDS-T) were tested in 108 patients (72 male; mean age, 43.2 +/- 11.2 years) with post-traumatic elbow stiffness. Cronbach's alpha was used to assess internal consistency. The intraclass correlation coefficients were used to estimate test-retest. Construct validity was analyzed with the Turkish version of the Disabilities Arm, Shoulder and Hand (DASH), the Mayo Elbow Performance Score (MEPS), and the Short Form-12 (PCS-12 and MCS-12). The SHEDS-T showed sufficient internal consistency (Cronbach's alpha coefficient = 0.83) and test-retest reliability (ICC = .96). The correlation coefficients between the SHEDS-T, the DASH, and the MEPS were .75 and .54, respectively (p < .001). There was a moderate correlation between the SHEDS-T and PCS-12 (r = .65, p = .01) and a weak positive correlation between the SHEDS and the MCS-12 (r = .40, p = .03). The SHEDS-T has sufficient reliability and validity to measure elbow-related symptoms and elbow motion capacities for Turkish-speaking individuals with post-traumatic elbow stiffness.
