Psychometric properties of the WHOQOL-HIV Bref for quality of life assessment

Abstract Objective: To evaluate the psychometric properties of the WHOQOL-HIV Bref questionnaire in people with HIV / AIDS. Method: The questionnaire was applied to 226 people living with HIV/AIDS in the Northern part of the state of Minas Gerais. The psychometric properties were evaluated by construct validity, reliability analysis, and criteria validity. Results: The model with six domains had an acceptable adjustment (χ2 / gl = 1.77, p <0.001, GFI = 0.85, CFI = 0.89, RMSEA = 0.058). The WHOQOL-HIV Bref showed statistically significant correlations among the six domains, satisfactory internal consistency and reproducibility. The instrument scores showed a significant correlation with the general quality of life score and the items that assess the self-perception of quality of life and health, a significant correlation with the overall result of depression, and statistically significant differences between subgroups of patients. Conclusions: The WHOQOL-HIV Bref was valid, reliable to measure the quality of life of people with HIV/AIDS.
