VALIDATION OF THE TURKISH VERSION OF THE WHOQOL-AGE AND A PROPOSED ALTERNATIVE SCALE STRUCTURE

Abstract

Purpose: The WHOQOL-AGE is a combination of the EUROHIS-QOL.8 and the short version of the WHOQOL-OLD. The aim of the present study is to explore the psychometric properties of the Turkish version of the WHOQOL-AGE in terms of its validity and reliability.Methods: Internal consistency, item–total correlations, and item success were analyzed taking the original structure into account. The validity tests consisted of construct validity and criterion validity analyses. The original scale structure was compared with a proposed new scale structure, comprised of two domains and based on the exploratory and confirmatory factor analysis, in terms of goodness-of-fit measures.Results: The mean age of the sample population (n = 550) was 73.09 ± 6.77, and 58.9% were female. Skewness and kurtosis were both within accepted limits (
