Abstract

The purpose of the current study is to test the validity and reliability of WHO quality of life scale short form (WHOQOLBref ) in Kazakh language. In this sense, a total sum of 509 students, 208 men (40.9%) and 301 women (59.1), volunteered in the study. The scale was made up of 26 items and 5 sub-dimensions (General Health, Physical Health, Psychological Health, Social Relations and Environment). In the analysis of the study, Confirmatory Factor Analysis was used regarding the structural validity of the inventory and Cronbach Alpha reliability analysis was used to determine internal consistency. In the confirmatory factor analysis results, goodness of fit index values were found as x2/sd(x2=936.08, sd=289)=3.23, GFI=0.88, CFI=0.86, NFI=0.80, RMSEA=0.66, SRMR=0.52, RMR=0.47. Internal consistency coefficient numbers were determined as 0.60 and 0.90. As a conclusion, it is likely to say that "WHO Quality of Life Scale Short Form (WHOQOL-Bref ) in Kazakh Language" is a valid and reliable assessment tool.
