Few cross-cultural measures are available to assess quality of life (QoL) in HIV/AIDS. A short form of the WHOQOL-HIV-the WHOQOL-HIV BREF-was developed and tested. Survey data from 1,923 HIV-positive adults (selected for age, gender and disease stage) were collected in 8 culturally diverse centres. The 'best' HIV-specific item was extracted from five HIV facets of the WHOQOL-HIV long form using information about item correlations with QoL, health and domains, item discriminant validity and centre problems. The five identified items were then integrated with the WHOQOL-BREF to complete the 31 item WHOQOL-HIV BREF. This short form shows good internal consistency reliability and discriminant validity for 'known' disease stages. Confirmatory factor analysis showed an overall good fit for a six domains model (Comparative Fit Index = .97), supporting scoring. Quality of life in different cultures is reported. A value of the WHOQOL-HIV short form is in monitoring QoL in multinational clinical trials, and in clinical practice.
Assessment of quality of life and its associated factors among people living with HIV/AIDS
HIV & AIDS Review
Introduction: Acquired immunodeficiency syndrome (AIDS) has evolved from a mysterious illness to a global pandemic which has infected tens of millions of people. Assessing health-related quality of life (HQOL) is useful for documenting the patients' perceived burden of chronic disease, tracking changes in health over time, assessing the effects of treatment and quantifying the return on health care investment. The study aimed to assess the quality of life and its associated factors in patients with HIV/AIDS. Material and methods: It was a hospital-based observational study conducted at the anti-retroviral therapy centre of the civil hospital, Nashik District. A total of 100 participants with confirmed HIV/ AIDS were included. The WHOQOL-HIV BREF instrument was used to assess the quality of life of people living with HIV/AIDS (PLHAs). Multivariate logical regression was used to study the factors affecting the quality of life of PLHAs. Results: The mean scores of HQOL was highest in the domain of spirituality (15.99) followed by the physical domain (14.71), level of independence (14.45), social relationships (14.04), psychological domain (13.26), and environment (13.04), and the overall perception of quality of life and general health perception's scores were 13.28 and 12.84. Conclussions: These findings highlight the need for enhanced socio-psychosocial support and a better environment for improving the health-related quality of life among PLHAs.
We sought to assess the reliability and construct validity of the HIV/AIDS-Targeted Quality of Life instrument (HAT-QoL) and the Medical Outcomes Study HIV Health Survey (MOS-HIV) adapted for use in Shona-speaking rural Zimbabwe. HAT-QoL and MOS-HIV were translated and culturally adapted into Shona, and administered to a convenience-sample of 400 patients with HIV-related opportunistic infections. HIV disease severity and bereavement history were assessed. Factor analysis of the HAT-QoL items produced seven factors that were nearly identical to the factor structure reported for an American sample that was the basis for the current HAT-QoL scales. Factor analysis of the MOS-HIV scales resulted in a single factor, not the expected two-factor structure (physical and mental). Convergent and discriminant validity assessments confirmed, in general, that similar Shona HAT-QoL and MOS-HIV dimensions were correlated and dissimilar ones not correlated. Construct validity assessments indicated that, on the whole, most Shona HAT-QoL and MOS-HIV dimensions were capturing anticipated subgroup differences. The exceptions were the Shona MOS-HIV dimensions of general health perceptions, cognitive function, and the quality of life (QoL) item. The reliability and validity of most Shona-adapted HAT-QoL and MOS-HIV dimensions suggest that both instruments are likely useful in measuring the QoL of rural, Shona-speaking populations in Zimbabwe, Mozambique, Zambia, and Botswana.

Introduction: The aim of this study was to assess validity and reliability of Persian version of quality of life (QOL) questionnaire in people living with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) (WHOQOL-HIV-BREF). Material and methods: A total of 150 HIV/AIDS patients who were referred to Fasa and Larestan Beha vioral Disease Counseling Centers were recruited into the study. WHOQOL-HIV-BREF questionnaire was completed by trained interviewers. Reliability of questionnaire was measured using Cronbach's a coefficient. Construct validity was assessed by item-scale correlation method, and criterion validity was determined with discriminant validity and convergent validity. Results: Cronbach's α was computed above 0.8 for all dimensions of the questionnaire. Item-convergent validity ranged from 0.38 to 0.83. QOL score was higher in AIDS patients compared with HIV-infected individuals in all dimensions (p < 0.01). Conclusions: The findings of this study show that WHOQOL-HIV-BREF questionnaire provide acceptable validity and reliability for measuring QOL among Persian-speaking HIV/AIDS-infected patients in Iran.

The Missoula-Vitas Quality-of-Life Index (MVQOLI) is a unique tool specifically designed to measure quality of life (QOL) in advanced illness in a palliative care setting. The aim of this study was to explore its cross-cultural validity. We used a culturally adapted version in a local language, Luganda, and tested the MVQOLI-M in 200 patients with advanced AIDS in urban Kampala, Uganda. Content validity was assessed using the content validity ratio approach. Reliability was assessed using Cronbach's alpha (a), and test-retest reliability was evaluated using the intraclass correlation coefficient. All items and domains were rated content valid and there was good construct validity. The instrument demonstrated good internal consistency (a ¼ 0.83). The transcendence domain was the best predictor of overall QOL. The MVQOLI-M is an acceptable, valid, and reliable measure of QOL for people with advanced AIDS and findings demonstrate the importance of measuring the transcendence domain in QOL in advanced illness.

Quality of life (QOL) assessments that are easily administered and which do not impose a great burden on the respondent are needed for use in large epidemiological surveys, clinical settings and clinical trials. Using data from the WHOQOL-BREF field trials, the objectives of this work are to examine the performance of the WHOQOL-BREF as an integrated instrument, and to test its main psychometric properties. The WHOQOL-BREF is a 26-item version of the WHOQOL-100 assessment. Its psychometric properties were analysed using cross-sectional data obtained from a survey of adults carried out in 23 countries (n ¼ 11,830). Sick and well respondents were sampled from the general population, as well as from hospital, rehabilitation and primary care settings, serving patients with physical and mental disorders and with respect to quotas of important socio-demographic variables. The WHOQOL-BREF self-assessment was completed, together with socio-demographic and health status questions. Analyses of internal consistency, item-total correlations, discriminant validity and construct validity through confirmatory factor analysis, indicate that the WHOQOL-BREF has good to excellent psychometric properties of reliability and performs well in preliminary tests of validity. These results indicate that overall, the WHOQOL-BREF is a sound, cross-culturally valid assessment of QOL, as reflected by its four domains: physical, psychological, social and environment.

The aim of the current study was to examine the factor structure and the psychometric properties of the European Portuguese version of the World Health Organization's Quality of Life Instrument in HIV Infection (WHOQOL-HIV-Bref). Exploratory factor analysis (EFA) and confirmatory factors analysis (CFA) were conducted on self-reported WHOQOL-HIV-Bref data from 1196 HIV-positive patients, frequenting the main departments of infectious diseases in Portugal. An EFA with a randomly chosen subsample suggested a five-domain structure for the WHOQOL-HIV-Bref. CFA validated this five-domain structure in a separate subsample, but also revealed that the original six-domain model fit the data. Accordingly, it was decided to use the original factor structure. Based on the original six domain structure, the European Portuguese version of WHOQOL-HIV-Bref showed acceptable internal consistency (alpha range: 0.61–0.80 across domains). All domains (with exception of Spirituality) clearly discriminated subjects considering the CD4+ T cell count subgroups. These findings revealed additional insights about the factor structure of the WHOQOL-HIV-Bref and provided evidence in support of the original six-domain structure. This instrument showed to be a cross-culturally valid measure of quality of life, particularly useful when addressing the impact of HIV not only on physical and psychological well-being but also on several domains beyond health.
