Resumo Objetivo: Avaliar as propriedades psicométricas do questionário WHOQOL-HIV Bref em pessoas com HIV/AIDS. Método: O instrumento foi aplicado a 226 pessoas com HIV/AIDS do Norte de Minas Gerais. As propriedades psicométricas foram avaliadas pela validade de construto, análise da confiabilidade e validade de critério. Resultados: O modelo com seis domínios apresentou ajustamento aceitável (χ2/gl= 1,77, p <0,001, GFI = 0,85, CFI= 0,89, RMSEA = 0,058 ). O WHOQOL-HIV Bref apresentou correlações estatisticamente significativas entre os seis domínios, consistência interna e reprodutibilidade satisfatórias. Os escores dos domínios demonstraram correlação significativa com o escore da qualidade de vida geral e dos itens que avaliam a autopercepção da qualidade de vida e da saúde, correlação significativa com o resultado global da depressão e diferenças estatisticamente significativas entre subgrupos de pacientes segundo variáveis socioeconômicas e clínicas. Conclusões: O WHOQOL-HIV Bref apresentou-se válido, confiável para medir a qualidade de vida de pessoas com HIV/AIDS.

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.

Abstract INTRODUCTION: Quality of life (QoL) is important for people living with HIV/AIDS, particularly as the disease progresses. This study evaluated the QoL of people living with HIV/AIDS (PLWHA), as well as its predictors, in one of the most impoverished regions of Brazil. METHODS: This cross-sectional study was conducted with patients older than 18 years with HIV/AIDS from two specialized HIV/AIDS care centers in the city of Montes Claros between 2013 and 2014. Sample size was calculated considering the estimates of mean scores for various dimensions of the European Portuguese version of the World Health’s Organization Quality of Life Instrument in HIV Infection (WHOQOL-HIV Bref). The following parameters were adopted: CI of 95%, estimated mean scores for QoL equal to 15, estimated variance for QoL scores equal to 16, and 5% relative margin of error. An increase of 20% was established to compensate for possible non-responses or losses, and correcting any design effect, adopting a deff equal to 2.0. Calculations revealed the need to interview at least 221 patients. Therefore, 226 patients living with HIV/AIDS were randomly selected. RESULTS: A total of 226 patients with mean age 43.7 years were evaluated: 51.8% men, 51.8% unemployed, 51.8% with low schooling level, 89.8% used antiretrovirals, and 43.3% experienced depression. Despite this, data indicated that 65% self-assessed their QoL as good and very good. Low QoL was associated with sociodemographic variables and some clinical variables. CONCLUSIONS: Depression was the main predictor of low QoL in all domains evaluated.
