Abstract

Abstract

Objective The objective of the study was to assess the reliability and validity of the World Health Organization quality of life scale-brief form questionnaire (WHOQOL-BREF) and compare the quality of life among HIV cases, providing a basis for evaluating the quality of life and formulating effective measures of HIV cases. Methods HIV cases were recruited through convenience sampling method in Honghe Hani-Yi Autonomous Prefecture, Yunnan Province. Reliability was assessed by using Cronbach's α and split-half reliability, while exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to assess its validity. ANOVA were used to compare the scores of different characteristics. Results A total of 410 valid questionnaires were obtained. Cronbach's α of WHOQOL-BREF and physical, psychological, social relationships, environment of WHOQOL-BREF were 0.901, 0.779, 0.819, 0.729, 0.743 respectively. The related correlation coefficients of split half were 0.798, 0.716, 0.822, 0.736, 0.697 respectively. Exploratory factor analysis obtained four communal factors, with a contribution of 54.542% to the overall variance. The results of the confirmatory factor analysis showed that the main indicators of the fitted model were χ²/df and the root-mean-square error of approximation (RMSEA), and the value were 2.169 and 0.076 respectively. Goodness of fit index (GFI), comparative fit index (CFI) and Tucker-Lewis index (TLI) were 0.820, 0.861 and 0.844 respectively. All value were closed to 0.900, indicating an accepted level. ANOVA results showed that there were different quality of life among HIV cases with different characteristics such as receiving antiretroviral therapy or not, ethnicity, occupation, education and last CD4⁺T lymphocyte count. Conclusion The reliability and validity of the WHOQOL-BREF are good, and quality of life varied by different characteristics of HIV cases prompting the intervention strategies pertinently.
