Examining The Factorial Structure and Measurement Equivalence/Invariance of The Quality of Life Scale “WHOQOL-BREF” Between Males and Females in Saudi Society

Abstract

Abstract:

This study aimed to translate and confirm the factorial

This study aimed to translate and confirm the factorial structure of the Quality of Life scale " WHOQOL-BREF " developed by the World Health Organization, as well as to examine the measurement equivalence/invariance across males and females in Saudi society. It also sought to explore the level of quality of life among a sample of adults in Saudi society (N=1916). The results concluded that the confirmatory factor analysis showed that the four-factor model was the best-fitting model (CFI= 0.93) and (RMSEA= 0.05), stratified Cronbach alpha reliability was (0.93), and four levels of measurement equivalence/ invariance were achieved (Configural, Metric, Scalar, and Residual) between males and females. The findings also showed high levels of quality of life among a sample of adults in Saudi society.
