The Continuous Dependence and Numerical Approximation of the Solution of the Quasilinear Pseudo-Parabolic Problem with Periodic Boundary Condition

In this paper we consider a pseudo- parabolic equation with a periodic boundary condition and we prove the stability of a solution on the data. We give a numerical example for the stability of the solution on the data

The Validity and Reliability Study of WHO Quality of Life Scale Short Form (WHOQOL-Bref) in Kazakh Language

The purpose of the current study is to test the validity and reliability of WHO quality of life scale short form (WHOQOL- Bref ) in Kazakh language. In this sense, a total sum of 509 students, 208 men (40.9%) and 301 women (59.1), vol- unteered 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 de- termine 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 consis- tency 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
