Abstract
To translate and culturally adapt the Mayo Elbow Performance Score (MEPS), a widely used instrument for evaluating disability associated with elbow injuries, into Turkish (MEPS-T) and to determine psychometric properties of the translated version. The MEPS was translated into Turkish using published methodological guidelines. The measurement properties of the MEPS-T (construct validity and floor and ceiling effects) were tested in 91 patients with elbow pathology. The reproducibility of the MEPS-T was tested in 59 patients over 7–14 days. The responsiveness of the MEPS-T was tested in a subgroup of 46 patients diagnosed with lateral epicondylitis and who received conservative treatment for 6 weeks. The interclass correlation coefficient (ICC) was used to estimate the test–retest reliability. The construct validity was analyzed with the disabilities of the arm, shoulder and hand (DASH), Visual Analog Scale (VAS) and the Short Form 36 (SF-36). Effect size (ES) was used to assess the responsiveness. The distribution of floor and ceiling effects was determined. The MEPS-T showed very good test–retest reliability (ICC 0.89). The correlation coefficients between the MEPS-T and DASH and VAS were −0.61 and −0.53, respectively (p < 0.001). The highest correlations were between the MEPS-T and the mental component summary (r = 0.47, p = 0.001) and role emotional (r = 0.45, p = 0.001). The MEPS-T ES, 0.50, was moderate (95 % CI 0.33–0.62). We observed no ceiling or floor effects. The MEPS-T represents a valid, reliable and moderately responsive instrument for evaluating patients with elbow disease.
