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.
