Psychometric properties of KIDSCREEN health-related quality of life questionnaire in Iranian adolescents
Health-related quality of life (HRQOL), which is receiving increasing attention, is a multidimensional concept that encompasses different areas including the physiological, psychological, social, and spiritual aspects of life. The KIDSCREEN-52 questionnaire is designed to measure the HRQOL of 8–18-year-old children and adolescents. The aim of this study was to develop a Persian version of KIDSCREEN-52 and analyze the validity and reliability of the translated version.
The KIDSCREEN-52 was translated into Persian in keeping with the international cross-cultural translation guidelines. A cross-sectional study was performed in the city of Tehran during 2012–2013. 328 students ranging in age from 8 to 18 years were enrolled in the study. The reliability for each dimension was estimated using Cronbach’s alpha coefficient. To examine the validity of the questionnaire, a confirmatory factor analysis (CFA) was conducted.
The Cronbach’s alpha coefficient was higher than 0.7 in all ten dimensions except self-perception. Validity of this questionnaire was confirmed by CFA. (Relative chi square (χ2/df) = 1.73; root-mean-square error of approximation = 0.047; normed fit index = 0.93; Tucker–Lewis index = 0.97; comparative fit index = 0.97; and relative fit index = 0.92.)
The Persian version of KIDSCREEN-52 is reliable and valid and can be used as a self-administered instrument for measuring HRQOL in children and adolescents in Iran.
