Abstract: BACKGROUND: Turkish version of the Upper Extremity Functional Index (UEFI) may help to assess shoulder function in patients with shoulder impingement syndrome (SAIS). OBJECTIVE: To translate and cross-culturally adapted UEFI into Turkish and to assess its acceptability, reliability, validity in patients with SAIS. METHODS: This study conducted with 93 SAIS participants. UEFI, the short version of the Disability of the Arm, Shoulder and Hand scale (Quick DASH), the Shoulder Pain and Disability Index, and the Short Form-36 Health Survey (SF-36) were administered. Acceptability was assessed in terms of refusal rate, rates of missing responses, and administration time. Test-retest reliability was assessed with intra class correlation coefficient (ICC), internal consistency was assessed with Cronbach's alpha coefficient. Validity was assessed by floor and ceiling effects, skew of distributions and Pearson's correlation coefficients. RESULTS: Cronbach's alpha coefficients for the UEFI at Time 1 and Time 2 were as follows: α = 0.89 and α = 0.89. Average measure ICC was 0.80. The UEFI score demonstrated strong negative correlations with SPADI total score and Quick DASH score. There was not a significant correlation between the UEFI and mental health subscale score derived from SF-36. CONCLUSIONS: The Turkish version of UEFI is acceptable, valid, and reliable.
