Adherence to Antiretroviral Therapy in People Living with HIV/AIDS: A Cross-Sectional Study.

Adherence to antiretroviral therapy (ART) is essential to suppress HIV replication, preserve immune competence, and ensure quality of life for people living with HIV/AIDS. This is a cross-sectional study to assess adherence to ART in HIV-infected adults and its associated factors in São Carlos, SP, Brazil, from June 2018 to January 2019. Standardized interviews were conducted covering demographic, clinical, and laboratory characteristics and instruments to assess compliance to treatment (CEAT-VIH), HIV/AIDS-targeted quality of life (HAT-QoL), and self-efficacy expectations of adherence (SEA-ART). Each variable was analyzed for association with adherence to ART, by refilling at least 90% of the prescribed doses in the 6 months before the interview date. The study consisted of 220 participants, with a mean age of 43 years, 60.5% male, and 24.5% men who have sex with men. Previous consumption of alcohol or illicit drugs was reported by 44.1% of participants and current or previous smoking by 34.1%. The most common regimen was two nucleoside reverse transcriptase inhibitors combined with one non-nucleoside reverse transcriptase inhibitor (37.3%). The adherence to ART was 62%, and the factors associated with it were living alone [adjusted odds ratio (aOR) 2.79], not having an active sexual life (aOR 0.43), not being a smoker (aOR 0.36), having a CD4 count ≥350 cells/mm3 (aOR 2.50), and having a SEA-ART Score >100 (aOR 1.94). The fear of disclosing HIV status could make adherence to treatment difficult. This could be the reason that living alone and not having an active sexual life have been associated with better adherence. Encouraging healthy lifestyle habits and promoting self-efficacy tools can also improve adherence.

Use of quality-of-life instruments for people living with HIV: a global systematic review and meta-analysis.

IntroductionDue to the effectiveness of combined antiretroviral therapy and its growing availability worldwide, most people living with HIV (PLHIV) have a near‐normal life expectancy. However, PLHIV continue to face various health and social challenges that severely impact their health‐related quality‐of‐life (HRQoL). The UNAIDS Global AIDS Strategy discusses the need to optimize quality‐of‐life, but no guidance was given regarding which instruments were appropriate measures of HRQoL. This study aimed to review and assess the use of HRQoL instruments for PLHIV.MethodsWe conducted a global systematic review and meta‐analysis, searching five databases for studies published between January 2010 and February 2021 that assessed HRQoL among PLHIV aged 16 years and over. Multivariable regression analyses were performed to identify factors associated with the choice of HRQoL instruments. We examined the domains covered by each instrument. Random‐effects meta‐analysis was conducted to explore the average completion rates of HRQoL instruments.Results and discussionFrom 714 publications, we identified 65 different HRQoL instruments. The most commonly used instruments were the World Health Organization Quality‐of‐Life‐ HIV Bref (WHOQOL‐HIV BREF)—19%, Medical Outcome Survey‐HIV (MOS‐HIV)—17%, Short Form‐36 (SF‐36)—12%, European Quality‐of‐Life Instrument‐5 Dimension (EQ‐5D)—10%, World Health Organization Quality‐of‐Life Bref (WHOQOL BREF)—8%, Short Form‐12 (SF‐12)—7% and HIV/AIDS Targeted Quality‐of‐Life (HAT‐QOL)—6%. There were greater odds of using HIV‐specific instruments for middle‐ and low‐income countries (than high‐income countries), studies in the Americas and Europe (than Africa) and target population of PLHIV only (than both PLHIV and people without HIV). Domains unique to the HIV‐specific instruments were worries about death, stigma and HIV disclosure. There were no significant differences in completion rates between different HRQoL instruments. The overall pooled completion rate was 95.9% (95% CI: 94.7−97.0, I 2 = 99.2%, p < 0.01); some heterogeneity was explained by country‐income level and study type.ConclusionsA wide range of instruments have been used to assess HRQoL in PLHIV, and the choice of instrument might be based on their different characteristics and reason for application. Although completion rates were high, future studies should explore the feasibility of implementing these instruments and the appropriateness of domains covered by each instrument.

Changes health-related quality of life in HIV-infected patients following initiation of antiretroviral therapy: a longitudinal study

BackgroundSeveral tools have been developed to evaluate HIV health-related quality of life (HRQoL) during and after antiretroviral therapy (ART). Few longitudinal studies evaluated the effect of ART on the quality of life of HIV patients. ObjectiveTo evaluate changes in HRQoL in HIV-infected individuals one year after initiating ART. MethodsA prospective study was conducted from May 2016 to July 2018. Data on clinical and sociodemographic characteristics of 91 HIV-infected patients were collected prior to initiation of ART and one year thereafter. Demographic and clinical data were collected and the questionnaires 36-item Short Form Health Survey (SF-36) and HIV/AIDS-targeted quality of life (HAT-QoL) were administered in both periods. Asymptomatic individuals, aged ≥18 years, were included in the study. Patients who discontinued treatment were excluded. The association between predictors of physical and mental HRQoL was analyzed by multiple linear regression analysis. ResultsPatients were predominantly male (78.0%), mean age 35.3 ± 10.7 years, with no stable relationship (80.2%), and no comorbidities (73.6%). Most of the SF-36 domains improved after one year, particularly Physical Function (p = 0.0001), General Health (p = 0.0001), Social Functioning (p = 0.0001), Mental Health (p = 0.001), and Mental Component Summary (p = 0.004). HAT-QoL domains improved in the Overall Function (p = 0.0001), Life Satisfaction (p = 0.0001), Provider Trust (p = 0.001), and Sexual Function (p = 0.0001) domains. Sex (p = 0.032), age (p = 0.001), income (p = 0.007), and stable relationship (p = 0.004) were good predictors of the Physical Component Summary. Sex (p = 0.002) and stable relationship (p = 0.038) were good predictors of the Mental Component Summary. SF-36 and HAT-QoL scales presented strong correlations, except for Medication Concerns (0.15–0.37), HIV Mastery (0.18–0.38), Disclosure Worries (−0.15 to 0.07), and Provider Trust (−0.07 to 0.15). ConclusionsART improved HRQoL after one year of use. The HAT-QoL and SF-36 correlated well and are good tools to evaluate HRQoL in HIV-infected patients on ART.

Gender, HIV-Related Stigma, and Health-Related Quality of Life Among Adults Enrolling in HIV Care in Tanzania.

HIV-related stigma has been associated with worse health-related quality of life (HRQoL) among people living with HIV (PLWH). Little is known about how different types of HIV-related stigma (i.e., anticipatory, internalized, or enacted HIV-related stigma) influence HRQoL and whether these relationships differ by gender. The sample included 912 PLWH aged 18 years or older enrolling in HIV care at four health facilities in Tanzania. HRQoL was assessed with the life satisfaction and overall function subscales of the HIV/AIDS-Targeted Quality of Life (HAT-QoL) instrument. Sex-stratified multivariable logistic regression modeled the association of anticipatory, internalized, and enacted HIV-related stigma on poor HRQoL. Across all participants, the mean life satisfaction score was 63.4 (IQR: 43.8, 81.3) and the mean overall function score was 72.0 (IQR: 58.3, 91.7). Mean HRQoL scores were significantly higher for women compared to men for overall function (5.1 points higher) and life satisfaction (4.3 points higher). Fourteen percent of respondents reported recent enacted HIV-related stigma and 13% reported recent medium or high levels of internalized stigma. In multivariable models, high internalized and high anticipatory stigma were significantly associated with higher odds of poor life satisfaction and poor overall function in both men and women. Psychosocial interventions to prevent or reduce the impact of internalized and anticipatory stigma may improve HRQoL among persons in HIV care. Future research should longitudinally examine mechanisms between HIV-related stigma, poor HRQoL, and HIV care outcomes.

Quality of life of people with HIV/AIDS - the influence of social determinants and disease-related factors.

This study assessed the quality of life (QoL) of people with HIV/AIDS. This cross-sectional epidemiological study was conducted at a specialized HIV/AIDS health facility of the Brazilian Public Health Service. Data were collected using the HIV/AIDS-Targeted Quality of Life (HAT-QoL) instrument. The study included 109 participants. Among the many significant statistical associations found in the study, the variables that had a greater effect on the domains assessed by the instrument were educational level, occupation, financial situation, ethnicity, and symptomatology. Sociodemographic factors and HIV/AIDS-related aspects were influential in the QoL of people living with HIV/AIDS.

Health-related quality of life in HIV/AIDS patients on antiretroviral therapy at a tertiary care facility in Zimbabwe

ABSTRACTHealth-related quality of life (HRQoL) is a broad concept reflecting a patient’s general subjective perception of the effect of an illness or intervention on physical, psychological and social aspects of their daily life. HRQoL among patients infected with HIV has become an important indicator of impact of disease and treatment outcomes. A cross-sectional survey was carried out at Chitungwiza Central Hospital, Zimbabwe, to assess HRQoL in patients with HIV/AIDS receiving antiretroviral therapy (ART), using two validated instruments. The HIV/AIDS-targeted quality of life (HAT-QoL) and EuroQoL Five-dimensions-Three-level (EQ-5D-3L) instruments were used to assess HRQoL. Internal consistency reliability and convergent validity of the two instruments were also evaluated. For construct validity, the relationships between HRQoL scores and socio-economic and HIV/AIDS-related characteristics were explored. The median scores for the HAT-QoL dimensions ranged from 33.3 (financial worries) to 100 (HIV mastery). A considerably low HAT-QoL dimension score of 50.0 was observed for sexual function. There were ceiling effects for all HAT-QoL dimension scores except for financial worries and disclosure worries. Floor effects were observed for financial worries and sexual function. The median of the EQ-5D-3L index and visual analogue scale (VAS) was 0.81 and 79.0, respectively. There were no floor or ceiling effects for both the EQ-5D-3L index and VAS. The overall scale Cronbach’s alpha was 0.83 for HAT-Qol and 0.67 for EQ-5D-3L. HAT-QoL demonstrated good convergent validity with EQ-5D index (0.58) and VAS (0.40). A higher level of HRQoL was positively and significantly related to income, education and employment. The patients’ self-reported HRQoL was generally satisfactory in all the HAT-QoL dimensions as well as the two components on the EQ-5D-3L instrument. The two instruments demonstrated good measurement properties in HIV/AIDS patients receiving ART and have potential for use, alongside biomarkers, in monitoring outcomes of interventions.

Quality of life of people living with HIV/AIDS treated by the specialized service in Vitória-ES, Brazil.

The aim of this study is to establish the factors that influence the quality of life of people living with HIV/AIDS being treated at a specialized public service. The participants answered the questionnaire on sociodemographic conditions, issues related to HIV and daily habits. The quality of life was analyzed using the HIV/AIDS-targeted quality of life (HAT-QoL) instrument with 42 items divided into 9 fields: General Activity, Sexual Activity, Confidentiality Concerns, Health Concerns, Financial Concerns, HIV Awareness, Satisfaction with Life, Issues related to Medication and Trust in the Physician. Bivariate and multiple linear regressions were performed. Of the participants, 53.1% were women and had a mean age of 42 years. In analyzing the quality of life, the HAT-QoL domain with the lowest average was Financial Concerns (39.4), followed by Confidentiality Concerns (43.2), Sexual Activity (55.2) and Health Concerns (62. 88). There was an association between the variables: not being gainfully employed (p < 0.001), being mulatto or black (p = 0.045) and alcohol consumption (p = 0.041) with the worst quality of life scores. Inadequate socioeconomic and health conditions had a negative impact on the quality of life of people with HIV/AIDS.

Quality of life of pregnant women infected with the human immunodeficiency virus (HIV) in the city of São Paulo

It was to assess the quality of life (QOL) of HIV-infected pregnant women using the HIV/AIDS - Targeted Quality of Life (HAT-QoL) questionnaire. A descriptive study of 60 pregnant women attended at the Multidisciplinary Nucleus of Infectious Diseases During Pregnancy (NUPAIG) - UNIFESP/EPM and in the referral network of the Municipal Office of São Paulo, conducted from February 2011 to October 2012. Sociodemographic and clinical variables were collected from 60 HIV-infected pregnant women who answered the HAT-QoL questionnaire, which included 34 questions about quality of life. The average age was 30 years and the average period of HIV infection was 5.7 years. Only 8.3% of patients had a CD4 cell score of ≤200 cells/mm³ and 45% showed undetectable viral load. The average domain scores ranged from 47.5 to 83.7. The domains with the lowest scores were financial concerns and concerns about secrecy. The domains with the highest scores and lower impact on quality of life were concerns about medication and confidence in the professional. In this initial study with 60 pregnant women, we concluded that the HAT-QOL can contribute to the assessment of quality of life in the population of HIV-infected pregnant women in Brazil.

Quality of life and related factors among people living with HIV/AIDS in Guangdong province

To explore the quality of life and related factors among people living with HIV/AIDS in Guangdong province. A total of 443 subjects older than age 18 who had been diagnosed as HIV/AIDS were recruited from AIDS Outpatient Clinic Departments in Guangzhou and Shenzhen. HIV/AIDS-targeted quality of life(HAT-QoL)scale was used to measure the quality of life on the patients. Nonparametric test method and multiple linear regression analysis were performed to explore the related factors. The average scores of the following nine domains of HIV/AIDS-targeted quality of life scales were:overall function as 59.89 ± 23.35, concerns on medication as 62.91 ± 24.01, worries on factors as being disclosed, on health, on financial situation were 19.97 ± 23.04, 54.05 ± 12.24 and 35.94 ± 26.45, respectively, trust on providers as 68.72 ± 26.17, rate of understanding HIV as 61.46 ± 25.72, on life satisfaction as 56.90 ± 25.30 and on sexual function as 50.82 ± 23.86. Factors associated with quality of life would include sex, age, residential area, education, employment, marital status, complications, HAART-related prescriptions, route of infection and duration of HIV/AIDS etc. The quality of life among HIV/AIDS patients had declined, especially on worries related to disclosure and financial situation. More attention should be paid on those with poor education, low income and lack of family support in order to improve their quality of life and reducing mortality.

Oral health associated with quality of life of people living with HIV/AIDS in Brazil

BackgroundThe epidemic of HIV/AIDS enters into its fourth decade and is still considered an important public health problem in developed and developing countries. The purpose is verify the oral health and other factors that influence the quality of life of people living with HIV/AIDS attending a public service reference in Brazil.MethodsThe participants answered the questionnaire on socio-demographic conditions, issues related to HIV and daily habits. The quality of life was analyzed by the HIV/AIDS Targeted Quality of Life (HAT-QoL) instrument with 42 items divided into nine domains: General Activity, Sexual Activity, Confidentiality concerns, Health Concerns, Financial Concern, HIV Awareness, Satisfaction with Life Issues related to medication and Trust in the physician. The oral health data were collected by means of the DMFT index, use and need of dentures and the Community Periodontal Index, according to the criteria proposed by the World Health Organization, by a calibrated researcher. Bivariate and multiple linear regressions were performed.ResultsOf the participants, 53.1% were women and had a mean age of 42 years, 53.1% had eight years or less of schooling and 20.3% were not employed. In analyzing the quality of life domain of the HAT-QoL, with a lower average there was: Financial concern (39.4), followed by Confidentiality concern (43.2), Sexual activities (55.2) and Health concerns (62. 88). There was an association between the variables: do not have link to employment (p <0.001), is brown or black (p = 0.045), alcohol consumption (p = 0.041), did not make use of antiretroviral therapy (p = 0.006), high levels of viral load (p = 0.035) and need for dentures (p = 0.025), with the worse quality of life scores.ConclusionSocioeconomic and inadequate health conditions had a negative impact on the quality of life of people with HIV/AIDS.

Using an innovative mixed method methodology to investigate the appropriateness of a quantitative instrument in an African context: Antiretroviral treatment and quality of life

The relationship between quality of life (QoL) and antiretroviral treatment (ART) has mainly been studied using quantitative scales often not appropriate for use in other contexts and without taking peoples' lived experiences into consideration. Sub-Saharan Africa has the highest incidence of HIV and AIDS yet there is paucity in research done on QoL. This research report is intended to give an account of the use of a mixed method convergent parallel design as a novice approach to evaluate an instrument's context specificity, appropriateness and usefulness in another context for which it was designed. Data were collected through a qualitative exploration of the experiences of QoL of people living with HIV or AIDS (PLHA) in Africa since being on ART, as well as the quantitative measurements obtained from the HIV/AIDS-targeted quality of life (HAT-QoL) instrument. This study was conducted in three African countries. Permission and ethical approval to conduct the study were obtained. Purposive voluntary sampling was used to recruit PLHA through mediators working in community-based HIV/AIDS organisations and health clinics. Interviews were analysed through open coding and the quantitative data through descriptive statistics and the Cronbach's alpha coefficient. A much wider range and richness of experiences were expressed than measured by the HAT-QoL instrument. Although an effective instrument for use in the USA, it was found not to be sensitive, appropriate and useful in an African context in its present form. The recommendations focus on adapting the instrument using the data from the in-depth interviews or to develop a context-sensitive instrument that could measure QoL of PLHA in Africa

Patient-Reported Quality of Life During Antiretroviral Therapy in a Nigerian Hospital

ObjectivesWe assessed the reported quality of life of patients with HIV/AIDS and explored the impact of patients’ sociodemographic profile on the quality-of-life domains. MethodsConsenting outpatients who met criteria were consecutively selected in a secondary health care facility in Benin City, Nigeria. Quality of life was determined in the nine domains of HIV/AIDS Targeted Quality of Life (HAT-QOL) instrument. Quality-of-life scores were computed on the scale of 0 to 100 and triangulated with a rated interval scale of 1 to 5 suited for quantitative analysis. Association between rated scores and each domain was explored by using Students’ t test and analysis of variance at 95% confidence interval. ResultsOut of the 403 patients, 82.1% were females; 147 (36.1%) belonged to the modal age group of 20 to 30 years; the mean age for grouped data was 39.2 years. About 239 (58.7%) were not married. Also, 338 (83.0%) earned below $1500 per annum and 303 (74.40%) had basic education (grade 1 to grade 9). HAT-QOL scores indicated the following: overall function (89.96 ± 5.62); life satisfaction (91.94 ± 3.62); health worries (87.06 ± 4.28); financial worries (81.00 ± 3.95); medication worries (91.65 ± 4.47); HIV mastery (71.00 ± 3.11); disclosure worries (27.50 ± 7.57); provider trust (91.63 ± 1.96); and sexual function (70.25 ± 3.51). Likert-type rated scores were in agreement with HAT-QOL scores. Provider trust was associated with gender, employment status, and educational level. Sexual function was associated with gender and age (P < 0.05). ConclusionsPatients reported satisfactory quality of life in the domains of overall function, life satisfaction, health worries, financial worries, medication worries, HIV mastery, provider trust, and sexual function. Quality of life was low in the domain of disclosure worries, indicating concerns for discrimination and stigmatization. Age, level of education, and employment status had a strong impact on the quality of life of patients with HIV/AIDs.

Symptoms of depression and quality of life of people living with HIV/AIDS

This is a cross-sectional study conducted with 228 people living with HIV/AIDS in a municipality in the State of São Paulo during 2007 and 2008. The aims of this study were to investigate the intensity of the depressive symptoms in individuals with HIV/AIDS treated at two referral units in Ribeirão Preto, Brazil, and to compare the quality of life with the different degrees of intensity of the depressive symptoms in these individuals, according to gender. Data were collected through individual interviews, using the Beck Depression Inventory and HIV/AIDS Targeted Quality of Life (HATQoL). A total of 63 (27.6%) patients with symptoms of depression (mild, moderate and severe) were detected. The women presented more severe symptoms of intensity of depression than men. Individuals with depressive symptoms presented lower scores of quality of life than individuals without these symptoms, with statistically significant differences between the means/medians in most domains of the HATQoL. Healthcare professionals should offer integral care for people with HIV/AIDS, emphasizing the depressive symptoms.

Quality of life in persons living with HIV–AIDS in three healthcare institutions of Cali, Colombia

Antecedents: The Human Immunodeficiency Virus is currently considered a chronic disease; hence, quality of life is an important goal for those suffering the disease or living with someone afflicted by the virus. Objectives: We sought to measure the quality of life in individuals living with acquired immunodeficiency syndrome virus and establish its relationship with socio-demographic and clinical variables. Methods: This is a cross-sectional, descriptive study with a sample of 137 HIV-infected individuals attending three healthcare institutions in the city of Cali, Colombia. Quality of life was measured via the HIV/AIDS-Targeted Quality of Life (HAT-QoL) instrument. The descriptive analyses included mean and standard deviation calculations. To determine the candidate variables, we used the student t test and the Pearson correlation. The response variable in the multiple linear regression was the score for quality of life. Results: Some 27% of the sample were women and 3% were transgender; the mean age of the sample was 35 + 10.2 years; 88% had some type of health insurance; 27% had been diagnosed with AIDS, and 64% were taking antiretroviral medications at the time of the study. Quality of life was measured through a standard scale with scores from 0 to 100. Participants’ global quality of life mean was 59 + 17.8. The quality-of-life dimensions with the highest scores were sexual function, satisfaction with the healthcare provider, and satisfaction with life. The highest quality-of-life scores were obtained by participants who received antiretroviral therapy, had health insurance, lower symptoms of depression, low frequency and intensity of symptoms, and no prior reports of sexual abuse. Eight variables explained 53% of the variability of the global quality of life. Conclusions: Those receiving antiretroviral therapy and who report fewer symptoms best perceived their quality of life. Implications for practice: Healthcare providers, especially nursing professional face a challenge in caring to alleviate symptoms and contribute to improving the quality of life of their patients.

The impact of herbal remedies on adverse effects and quality of life in HIV-infected individuals on antiretroviral therapy

Use of herbal remedies among HIV-infected individuals in Africa increased in the past decade, mainly due to traditional beliefs and at times inconsistent access to antiretroviral drugs. In Zimbabwe, accessibility and availability of antiretroviral drugs has increased in recent years; however, the use of herbal remedies remains high. This study was conducted to determine the impact of concomitant use of herbal remedies with antiretroviral drugs on adverse events and on quality of life. A convenient sample of HIV positive patients at Parirenyatwa group of hospitals' Family Care Clinic (Harare, Zimbabwe) was enrolled. A questionnaire was used to collect data on the adverse event experiences of the patients using herbal remedies for their HIV, as well as the types of herbal remedy used. Quality of life index was measured using an HIV/AIDS targeted quality of life (HAT-QOL) tool developed by the World Health Organization. Abdominal pain (odds ratio = 2.7, p-value = 0.01) and rash (odds ratio = 2.5, p-value = 0.02) had significant associations with using herbal remedies during antiretroviral therapy. Improved quality of life index was not significantly associated with herbal remedy use during antiretroviral therapy. There is evidence to suggest that some traditional herbal remedies used in Zimbabwe may increase incidence of certain types of adverse events when used in combination with antiretroviral drugs. Use of herbal drugs in combination with antiretroviral therapy does not significantly improve quality of life index in comparison to antiretroviral drug use only.

Quality of life in people living with HIV/AIDS in Niger Delta Region, Nigeria

Background: Despite the global efforts and huge financial investment in HIV/AIDS, the quality of life in people living with the disease continues to deteriorate, posing serious problems with increased mortality.Aim: The objectives of the study were: (i) to assess the quality of life in people living with HIV/AIDS, and (ii) to compare quality of life in males and females living with the disease.Methods: A total of 309 people living with HIV/AIDS from the HIV clinic, University of Uyo Teaching Hospital were randomly assessed for quality of life, using HIV/AIDS-Targeted Quality of life (HAT-QOL) questionnaire.Results: A total of 265 (85.8%) respondents consisting of 113 (36.6%) males and 152 (49.2%) females were analyzed. The mean age for males was 36.8 ± 4.0 years and females 31.9 ± 3.3 years. The difference in mean was statistically significant (t = 31.831, p < 0.01), occupation was statistically significant (χ2 = 11.348, p < 0.02). Females showed lower quality of life in comparable domains than males. The differences in life satisfaction (χ2 = 10.362, p < 0.01) and health worries (χ2 = 9.944, p < 0.01) were statistically significant.Conclusion: The results showed impairment in quality of life, except in medication worries and sexual function in people living with HIV/AIDS. Improvement in HAT-QoL indices will enhance positive quality of life.

Patterns of responses on health-related quality of life questionnaires among patients with HIV/AIDS.

Health-related quality of life (HRQoL) has become an important facet of HIV/AIDS research. Typically, the unit of analysis is either the total instrument score or subscale score. Developing a typology of responses across various HRQoL measures, however, may advance understating of patients' perspectives. In a multicenter study, we categorized 443 patients' responses on utility measures (time-tradeoff, standard gamble, and rating scale) and the HIV/AIDS-Targeted Quality of Life (HAT-QoL) scale by using latent profile analysis to empirically derive classes of respondents. We then used linear regressions to identify whether class membership is associated with clinical measures (viral load, CD4, time since diagnosis, highly active antiretroviral therapy [HAART]) and psychosocial function (depressed mood, alcohol use, religious coping). Six classes were identified. Responses across the HAT-QoL subscales tended to fall into 3 groupings--high functioning (Class 1), moderate functioning (Classes 2 and 3), and low functioning (Classes 4 to 6); utility measures further distinguished individuals among classes. Regression analyses comparing those in Class 1 with those in the other 5 found significantly more symptoms of depression, negative religious coping strategies, and lower CD4 counts among subjects in Class 1. Those in Class 5 had been diagnosed with HIV longer, and members of Class 6 reported significantly less alcohol consumption, had higher viral loads, and were more likely to receive HAART. Patients with HIV respond differentially to various types of HRQoL measures. Health status and utility measures are thus complementary approaches to measuring HRQoL in patients with HIV.

Two approaches to measuring quality of life in the HIV/AIDS population: HAT-QoL and MOS-HIV.

Reduce the number of HIV/AIDS-Targeted Quality of Life (HAT-QoL) items, assess psychometric performance of the shortened HAT-QoL, and compare psychometric performance of HAT-QoL to that of Medical Outcomes study HIV Health Survey (MOS-HIV). Convenience sample of 215 cross-sectionally studied seropositive individuals. Subjects completed the HAT-QoL, MOS-HIV, and sociodemographic and disease-specific questions. HAT-QoL and MOS-HIV responses were entered, separately, into principal components analysis (PCA). Results from PCA, internal consistency and correlation assessments were used to aid the item removal process. Dimension characteristics (e.g., score distributions, internal consistency, scaling success rates, intercorrelations, construct validity) were evaluated. PCA of subjects' (80% male; 45% white; 62% gay/bisexual) responses revealed nine previously identified HAT-QoL dimensions. The measure was shortened by removing 12 items. Two HAT-QoL dimensions (HIV mastery and provider trust) had ceiling effects. All internal consistency coefficients were > 0.80, except those for sexual function (0.57) and medication concerns (0.57). HAT-QoL scaling success rates were > 90% for 7 of 9 dimensions, and a majority of dimensions showed minimal to low intercorrelations. Validity assessments indicated consistent, expected relationships (p < or = 0.05) for all dimensions except the medication concerns and provider trust dimensions. PCA indicated five MOS-HIV factors. Six of the 11 previously defined MOS-HIV dimensions--physical, role, social, and cognitive function, pain, and health transition--had substantial ceiling effects. MOS-HIV scaling success rates were > 90% for only 2 out of 8 evaluable dimensions; three dimensions had very low (40-73%) scaling success rates. Most MOS-HIV dimensions were moderately-to-highly intercorrelated. Validity assessments indicated consistent, expected relationships for all MOS-HIV dimensions. Six dimensions of the shortened HAT-QoL instrument (overall function, disclosure worries, health worries, financial worries, HIV mastery, and life satisfaction) exhibited good psychometric properties, including limited ceiling effects, low dimension intercorrelations, high internal consistency, and evidence for construct validity. All multi-item MOS-HIV dimensions had high internal consistency and all dimensions revealed consistent evidence for construct validity.

A new HIV/AIDS-targeted quality of life (HAT-QoL) instrument: development, reliability, and validity.

The objectives of this study were to identify quality-of-life concerns, as reported by human immunodeficiency virus (HIV) seropositive individuals, and to develop a measure to assess these concerns. The HIV/acquired immunodeficiency syndrome (AIDS)-targeted measure was developed in two linked studies. In study one, group discussions with 42 HIV seropositive individuals were used to generate item content for the new measure. In study two, 201 HIV seropositive individuals were cross-sectionally studied to identify dimensions and to reduce the number of items of the quality of life questionnaire resulting from study one. Study one subjects (76% male; 66% white; 55% gay/bisexual) identified concerns captured by 76 items. Factor analysis indicated that responses of study two subjects (78% male; 42% white; 55% gay/bisexual) could be summarized by nine dimensions. Overall function, sexual function, disclosure worries, health worries, financial worries, HIV mastery, life satisfaction, medication concerns, and provider trust dimensions were refined by removing items using methods to maximize internal consistency and to minimize item redundancy. No substantial ceiling/floor effects existed, except for the provider trust dimension (43% received the highest score possible). All internal consistency coefficients were > or = 0.70, except those for the HIV mastery (0.57) and medication concerns (0.51) dimensions, as well as the sexual function dimension (0.56) in the non-AIDS subsample. Multitrait/multiitem assessment indicated scaling success rates that were high (> or = 91%) for eight of nine dimensions (HIV mastery revealed a lower but modest success rate of 79%). Validity assessments, using self-reported HIV disease severity and sociodemographic variables, indicated expected relationships for all dimensions. Five dimensions of the new HIV/AIDS-targeted quality of life instrument (overall function, disclosure worries, health worries, financial worries, and life satisfaction) exhibited good psychometric properties, including low ceiling/floor effects, good internal consistency, and evidence for construct validity.

Performance of a new, HIV/AIDS-targeted quality of life (HAT-QoL) instrument in asymptomatic seropositive individuals.

To evaluate the psychometric performance of a new human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS)-targeted quality of life (QoL) instrument in asymptomatic HIV-seropositive individuals. 201 urban and rural, HIV-seropositive subjects were recruited to complete a 76-item pilot QoL measure developed using content provided in group process by seropositive individuals. Questionnaire responses from the full sample (n = 201) were used to identify dimensions and to reduce the number of items to 42. The responses to the retained items were then analysed for the asymptomatic subsample (n = 106). 9 multi-item dimensions were identified: overall function (OF), sexual function (SF), disclosure worries (DW), health worries (HW), financial worries (FW), HIV mastery (HM), life satisfaction (LS), medication concerns (MC) and provider trust (PT). The responses by asymptomatic subjects (74% male, 64% non-White and 63% homosexual/bisexual) revealed no substantial floor or ceiling effects, except for the PT dimension (where 44% were found to have scored the highest score). The internal consistency coefficients (Cronbach's alphas) were between 0.80 and 0.89 for six dimensions. The coefficients were lower for the SF (0.52), HM (0.67) and MC (0.48) dimensions. Construct validity assessments, using self-reported HIV disease-severity and sociodemographic variables, revealed some significant relationships (p < or = 0.05) for all dimensions except SF, MC and PT. The results suggested that five dimensions (OF, DW, HW, FW and LS) from the new instrument have good psychometric properties for asymptomatic HIV-seropositive individuals. These dimensions may be useful in the study of asymptomatic, seropositive individuals' QoL. Four dimensions (SF, HM, MC and PS) require additional refinement for this subpopulation.
