The Turkish validity and reliability of the venous insufficiency epidemiological and economic study-quality of life/symptoms scales.

The aim of the study was to test Turkish validity and reliability of Venous Insufficiency Epidemiological and Economic Study-Quality of Life/Symptoms (VEINES-QoL/Sym) in patients with chronic venous insufficiency (CVI). A total of 118 patients with CVI hospitalized in 3 different hospitals were enrolled in this study. VEINES-QoL/Sym, translated to Turkish with a standard methodology, was applied to the patients and was evaluated for acceptability, reliability, validity, and responsiveness. Cronbach α (including if item deleted) values were used for the reliability analysis. Construct and criterion validity approaches were used for validity analysis. Cronbach α values are .86 for the VEINES-QOL and .81 for the VEINES-Sym. No problematic items were observed for the scale. The VEINES-QoL/Sym was significantly sensitive to clinical, etiology, anatomy, and pathophysiology (CEAP) classification, indicating good criterion validity. Significant correlation was found between scores of SF-36 and VEINESQoL (r = .43-.66). Turkish version of the VEINES-QOL/Sym was found reliable and valid for Turkish patients with CVI.
