Abstract

Abstract : Background: The Upper Limb Functional Index (ULFI) is a patient reported outcome measure with sound clinimetric properties and clinical viability for determination of upper limb status and impairment. To date, no validated Turkish version is available. Objectives: The purpose of this study is to cross-culturally adapted the ULFI for Turkish-speaking patients (ULFI-Tk) and determine the psychometric properties of reliability, validity, factor structure in a Turkish population with upper limb problems. Methods: The ULFI English version was culturally adapted and translated into Turkish and back-translated according to established guidelines. Patients (n=l02, 70% female, age 49.1±16.6) with upper limb disorders completed the ULFI-Tk at baseline and day-three for test-retest reliability. The Disability of Arm, Shoulder and Hand (DASH) Turkish version was concurrently completed as a criterion. Additional psychometric properties were determined for internal consistency (Chronbach's α), criterion validity and factor structure. Results: ULFI-Tk demonstrated good internal consistency (α=0, 87) and reliability (ICC=0.72, CI=0.58-0.80). Factor analysis demonstrated two factor structures, explaining 31, 23% of total variance. Pearson's correlation coefficient (r=0, 679;p<0, 05) revealed modarete criterion validity between the ULFI and DASH. Conclusions: The ULFI-TK demonstrated a 2 factor 25 item structure and is reliable and valid instrument. The ULFI-Tk consists of simple and easily understood words therefore it may be used to assess upper limb musculoskeletal disorders in Turkish speaking patients.
