Evaluation of a knowledge translation intervention for HIV and rehabilitation advocacy in physiotherapy in three sub-Saharan African countries.

PURPOSE: To evaluate a knowledge translation intervention to determine knowledge, attitudes and self-efficacy related to HIV and rehabilitation advocacy in physiotherapy students. METHODS: A pre and post-test study was conducted at three physiotherapy-training programs in Sub Saharan Africa - the University of the Witwatersrand (Wits), the University of Zambia (UNZA) and Kenya Medical Technical College (KMTC). For each site, the knowledge, attitude and self-efficacy of physiotherapy students were tested pre- and post-intervention using a standardized questionnaire. RESULTS: Students' knowledge improved with regard to being able to describe the challenges faced by their patients, knowing what resources are available and understanding their role as an advocate. In terms of self-efficacy, they felt more confident clinically, as well as being a resource person to colleagues and an advocate for their patients.This study highlights the need to contextualize knowledge translation interventions to meet the unique needs of individual academic sites. Students who have clinical experience working with people living with HIV are more likely to embrace their role as advocates in the area of HIV and rehabilitation.Implications for RehabilitationThe knowledge translation process used in this study gives a concrete example of how to use research evidence on HIV knowledge in rehabilitation applied within the advocacy process.Applying the principles of advocacy translates to understanding the management of HIV practically.Clinical experience in managing people living with HIV strengthens knowledge and improves the attitude of physiotherapy studentsPhysiotherapy students need guidance in realizing their potential as advocates for holistic rehabilitation care for people living with HIV.

Validity and reliability of the HIV Disability Questionnaire for people living with HIV in South Africa.

This study determined the measurement properties of the HIV Disability Questionnaire (HDQ) on a sample of people living with HIV (PLWHIV) to validate this assessment in a resource-limited environment. A quantitative, descriptive, cross-sectional research design was used with PLWHIV on antiretroviral therapy (ART) for six months or more. Participants completed the HDQ, World Health Organisation Disability Assessment Scale (WHODAS 2.0) and the Medical Outcomes Study - Social Support Survey (MOS-SSS). Disability presence, severity and episodic scores on the HDQ were tested against the WHODAS 2.0 and MOS-SSS to determine convergent and divergent construct validity and internal consistency. Results for the HDQ were compared to four other populations from high-income countries. Of the sample of 498 participants, 68% were female, the median age was 41 years and 19% had a median of one concurrent health condition. Median HDQ scores were 24.63 for disability presence, 10.14 for disability severity and 15.94 for the episodic scale. Moderate correlations confirmed 92.8% of convergent a priori hypotheses, while 85.7% of divergent a priori hypotheses were accepted. Cronbach's alpha for the HDQ scales ranged from 0.89 to 0.84. Results from the HDQ differed from those determined in Canada, Ireland, the United States and the United Kingdom, with presence and severity scores for the South African sample being lower. Episodic scores were higher, which may be related to the socio-economic context. The HDQ is reliable and valid for disability determination and may be used as a rehabilitation outcome measure for PLWHIV in South Africa.

Long COVID and episodic disability: advancing the conceptualisation, measurement and knowledge of episodic disability among people living with Long COVID - protocol for a mixed-methods study.

INTRODUCTION: As the prevalence of Long COVID increases, there is a critical need for a comprehensive assessment of disability. Our aims are to: (1) characterise disability experiences among people living with Long COVID in Canada, UK, USA and Ireland; and (2) develop a patient-reported outcome measure to assess the presence, severity and episodic nature of disability with Long COVID. METHODS AND ANALYSIS: In phase 1, we will conduct semistructured interviews with adults living with Long COVID to explore experiences of disability (dimensions, uncertainty, trajectories, influencing contextual factors) and establish an episodic disability (ED) framework in the context of Long COVID (n~10 each country). Using the conceptual framework, we will establish the Long COVID Episodic Disability Questionnaire (EDQ). In phase 2, we will examine the validity (construct, structural) and reliability (internal consistency, test-retest) of the EDQ for use in Long COVID. We will electronically administer the EDQ and four health status criterion measures with adults living with Long COVID, and readminister the EDQ 1 week later (n~170 each country). We will use Rasch analysis to refine the EDQ, and confirm structural and cross-cultural validity. We will calculate Cronbach's alphas (internal consistency reliability), and intraclass correlation coefficients (test-retest reliability), and examine correlations for hypotheses theorising relationships between EDQ and criterion measure scores (construct validity). Using phase 2 data, we will characterise the profile of disability using structural equation modelling techniques to examine relationships between dimensions of disability and the influence of intrinsic and extrinsic contextual factors. This research involves an academic-clinical-community partnership building on foundational work in ED measurement, Long COVID and rehabilitation. ETHICS AND DISSEMINATION: This study was approved by the University of Toronto Research Ethics Board. Knowledge translation will occur with community collaborators in the form of presentations and publications in open access peer-reviewed journals and presentations.

Strengths and Challenges of Implementing Physiotherapy in an HIV Community-Based Care Setting: A Qualitative Study of Perspectives of People Living with HIV and Healthcare Providers.

The needs of people living with HIV (PLWH) who have access to antiretroviral therapy have shifted from hospital to community care; however, little is known about physiotherapy within HIV community-based care. Our aim was to understand strengths and challenges of implementing physiotherapy within an interprofessional HIV day health program in Toronto, Ontario, Canada. We conducted a qualitative descriptive study using semi-structured interviews. Data were analyzed using inductive content analysis. Fifteen PLWH and 5 healthcare providers participated. Strengths included improved access to physiotherapy and fulfilling an unmet need for rehabilitation; a tailored approach to physiotherapy; co-location improved communication, coordination, and engagement in care; and improved health outcomes for PLWH (i.e. function, psychosocial outcomes, and quality of life). Challenges related to managing expectations; variable attendance at visits; and managing complex and diverse needs of PLWH. Results may be transferable to other community-based care settings that provide care for PLWH and complex multi-morbidity.

Acute effect of resistance exercise on cognitive function in people living with HIV.

People living with HIV are at an increased risk of developing cognitive deficits. Physical exercise is an important strategy to improve the brain health of people living with HIV. This randomized, controlled study aimed to investigate the acute effect of a single resistance exercise session on the cognitive function of people living with HIV. Twenty-three people living with HIV were randomized (1:1) to a control group (n = 12) or the exercise group (n = 11). Cognitive function was assessed by the Stroop test and the Trail Making Test. The exercise group was evaluated before and after the exercise session; meanwhile, the control group was evaluated before and after a 40-minute rest period. No statistical difference was found on the effect of exercise on cognitive function (p > 0.05). This result suggests that one session of resistance exercise was not capable of improving the cognitive function of people with HIV.

Feasibility and effects of high-intensity interval training in older adults living with HIV.

Adults with HIV on therapy can live a normal lifespan but exhibit advanced ageing which includes reduced cardiorespiratory fitness. Our objective was to determine the feasibility and effects of high-intensity interval training (HIIT) combined with resistance training (RT) in older adults with HIV. We conducted a cross-over pilot study within a randomized exercise trial in sedentary adults with HIV ≥50 years of age. First, participants were randomized to 4 months of continuous high-intensity aerobic exercise (AEX) and RT 3x/week or standard of care control. Then, the control group completed 4 months of HIIT + RT (3x/week). Among the 32 individuals enrolled, 26 eligible participants were randomized. Most participants were African American (63%) and male (95%) with a mean (SD) age of 61.5 (6.7) years and VO2peak of 24.5 (4.9) ml/kg/min. Attendance and adherence to both exercise training interventions were high. The clinically significant increases in VO2peak (ml/kg/min) after HIIT (3.09 ±1.04, p=0.02) and AEX (2.09 ±0.72, p=0.01) represented improvements of 17.1% and 7.7%, respectively. Both groups had improvements in exercise endurance (time on the treadmill) and strength (all p< 0.01). This pilot study supports HIIT as an efficient means to deliver high-intensity AEX to improve cardiorespiratory fitness toward the goal of attenuating the accelerated ageing process in adults with HIV.

Employment and Occupational Productivity Among Women Living With HIV: A Conceptual Framework.

ABSTRACT: Women living with HIV (WLWH) have lower employment rates and more difficulty finding and keeping employment compared with their counterparts without HIV. These disparities affect physical, psychological, and socioeconomic outcomes, and they may compound the disadvantages associated with living with HIV. Although historical literature has emphasized the impact of clinical factors on employment, current evidence suggests that socioeconomic and psychosocial factors associated with HIV should be included for a more comprehensive view. Based on this broader inclusion, a conceptual framework is presented describing how socioeconomic and psychosocial characteristics influence employment acquisition and maintenance among WLWH. The framework posits that there is a reciprocal relationship between employment acquisition and occupational productivity, and psychological health, physical health, social support, and empowerment. Implications for future research and interventions include (a) an extended conceptualization of vocational rehabilitation and (b) the use of peer support groups to increase social capital, empowerment, knowledge, and resources among WLWH.

HIV-related disability and rehabilitation: perception of health care workers.

Background: Health care workers play an integral role in the rehabilitation and care of people living with HIV who face multiple impairments and often disabilities. The aim of the article was to understand the perceptions and attitudes of health care workers towards caring for people living with HIV, and experiencing disability. Methods: Fifteen health care workers offering care to people living with HIV were interviewed using a semi-structured guide. These health care workers included doctors, a social worker, a pharmacist, a dietician, an occupational therapist, a physiotherapist, and nurses and HIV couPnsellors who were employed at a public health care facility in KwaZulu-Natal. Data from the interviews were transcribed and analysed using conventional content analysis. Results: Four themes emerged from semi-structured interviews with the health care workers: a holistic disability framework, a multidisciplinary team dynamic, organisational barriers and recommendations by health care workers. Conclusion: Health care workers perceived a shift from a biomedical perspective of disability to a bio-psychosocial interpretation that is influenced by contextual and environmental barriers imposed by communities on people living with HIV. Barriers included stigmatisation that leads to attitudinal barriers and social exclusion of people living with HIV and experiencing disabilities within communities. Lack of resources, including of equipment, and a shortage of health care staff also posed barriers to the care offered to people living with HIV and experiencing disabilities. Participants agreed that improved communication in the multidisciplinary health care team, as well as continuing education and training, would enable health care workers to offer improved, integrated care to people living with HIV who experience disabilities.

Child functioning and disability in children living with human immunodeficiency virus in a semi-rural healthcare setting in South Africa.

BACKGROUND: Children living with HIV (CLHIV) often experience HIV-related impairment and disability. AIM: The study sought to understand the level of child functioning and access to rehabilitative care in the context of South African healthcare in order to inform an integrated rehabilitative framework. SETTING: District level semi-rural healthcare facility in KwaZulu-Natal. METHODS: The Washington Group/United Nations International Children's Emergency Fund Module on Child Functioning, was administered to carers of CLHIV aged between 5 and 10 years, and accessing care at the study setting. RESULTS: Forty-four caregivers of children receiving treatment from June 2018 to March 2019, at the facility, participated. Four (9.1%) children had difficulty with seeing, 13 (29.5%) children had difficulty with hearing and 10 (22.7%) children had difficulty with walking. In the cognitive and behavioural domains, 17 (38.6%) children reported difficulties in communication and concentration, with 16 (36.4%) children experiencing difficulties in learning and remembering. Difficulties reported in accepting change and controlling behaviour were both experienced by 23 (52.3%) children. Although many children experiencing impairments were referred for rehabilitation, many caregivers did not follow-up after the initial assessment, because of financial constraints, lack of time and transport restrictions. CONCLUSION: Functional difficulties were frequently experienced by children living with HIV. Disability screening would be beneficial at various points of care to promote early identification and timely referral to healthcare professionals. Decentralising rehabilitative care to homes and communities could offer a solution to some of the reported barriers to accessing care.

Characterization of inpatient rehabilitation outcomes among HIV/AIDS patients: a retrospective cohort study.

ABSTRACT Survival time in HIV/AIDS patients has increased as a result of improved treatments, but many acquire functional impairments that may necessitate multidisciplinary medical rehabilitation. In the United States, inpatient rehabilitation facilities (IRF) provide this care, but outcomes are not well described in this population. We used the Uniform Data System for Medical Rehabilitation (UDSMR) database to describe 11,051 HIV/AIDS IRF patients; HIV/AIDS patients were grouped according to the following admission criteria: (1) HIV/AIDS as primary reason for admission (n = 225); (2) HIV/AIDS symptomatic comorbidity (n = 6569); and (3) HIV/AIDS asymptomatic comorbidity (n = 4257). We used standard descriptive statistics to summarize demographic, medical, rehabilitation, and discharge setting characteristics by group. When compared to patients with HIV/AIDS as a comorbidity, primary HIV/AIDS patients had worse outcomes. They made less functional change (25.1 versus 29.8 and 28.9, p < .001), went home less (73.8% versus 74.5% and 77.8%, p < .001) and to an acute care hospital more frequently (18.2% versus 13.9% and 10.1%, p < .001). These findings help to characterize the HIV/AIDS patient population who receive inpatient medical rehabilitation, which helps inform clinical care, and highlight the positive impact IRF care can make to minimize functional disability among chronic HIV/AIDS patients and possibly decrease costs of home health care.

Children living with HIV-related disabilities in a resource-poor community in South Africa: caregiver perceptions of caring and rehabilitation.

The care offered to children living with HIV (CLHIV) experiencing HIV-related disability is often challenged by caregiver illness, poverty and poor support structures in and around communities. Since caregiver needs directly influences the care offered to CLHIV this paper aimed to explore the experiences of the caregivers of CLHIV in order to inform an appropriate rehabilitation model in South Africa. A qualitative enquiry using in-depth interviews with 14 caregivers (one male and thirteen females) of CLHIV experiencing disability in a peri-urban setting was conducted. Data were analysed using thematic analysis. Four themes emerged from the interviews: understanding of HIV-related disability and rehabilitation, challengers to care and well-being, enablers to care; and perceived needs of caregivers. The study revealed that caregiver burden is influenced by the availability of resources and social support services. Financial constraints, poor access to rehabilitation and reduced support networks challenged the care offered to CLHIV. The perceived needs of the caregivers in this study included appeals for improved social security, housing, accessible rehabilitation and education. Changes in government policy guiding social support, employment, education and rehabilitation interventions are needed to improve the availability of resources, education, health and well-being of CLHIV and their caregiver's in South Africa.

Effects of speed of processing training and transcranial direct current stimulation on global sleep quality and speed of processing in older adults with and without HIV: A pilot study.

Some older adults with human immunodeficiency virus (HIV) experience poor sleep which can worsen cognition. Transcranial direct current stimulation (tDCS) and cognitive training have improved sleep and cognition in studies of older adults; yet, their combined influence is unknown in adults with HIV. Older adults with HIV (n = 33) and without HIV (n = 33) were randomized to receive 10 one-hour sessions of speed of processing (SOP) training with tDCS or sham tDCS over approximately 5 weeks. tDCS with SOP training did not improve sleep. Omitting correction of multiple comparisons for this exploratory pilot study, main effects for HIV (F[1, 59] = 5.26, p = .03, ηp2 = .082) and tDCS (F[1, 59] = 5.16, p = .03, ηp2 = .080) on the Digit Copy Test were detected. A HIV × tDCS interaction was detected on the Letter Comparison Test (F[1, 59] = 5.50, p = .02, ηp2 = .085). Useful Field of View scores improved across all four groups (F[1, 59] = 64.76, p < .001, ηp2 = .523). No significant effects for HIV (F[1, 59] = 1.82, p = .18) and tDCS (F[1, 59] = .01, p = .94) were detected on the Useful Field of View test. While the current study did not show effects of combined tDCS and SOP training on sleep quality, future studies are needed to examine the effects of such interventions on sleep-related cognitive functions among cognitively impaired adults with HIV.

A Rehabilitation Framework for Children Living With HIV in South Africa: Reaching Consensus for a Resource-Poor Community.

Although rehabilitation frameworks for adults living with HIV are developing steadily, interventions to ensure the integration of rehabilitation into the routine care of children living with HIV-related disabilities lags. We sought to explore perceptions of, and gain expert consensus on, a rehabilitation framework for children living with HIV. Experts in HIV pediatric care in South Africa engaged in a Delphi survey, based on findings from a context-specific rehabilitation framework for adults. Consensus was determined by an a priori threshold of 80% agreement and an interquartile range of 1 or lower on criteria to be included as essential or useful in the framework. Experts agreed that enhancing access to patient-centered care through decentralization and training of health care and community care workers in the use of disability screening tools at each point of care needed to be included in the framework. Strengthening multiprofessional team collaboration was also seen as fundamental.

Rehabilitation approaches for children living with HIV in sub-Saharan Africa: a protocol for scoping review.

BACKGROUND: A large number of children living with chronic conditions such as HIV experience impairments and disabilities. Current sub-Saharan African healthcare systems are challenged with paediatric care that does not integrate rehabilitation into management of chronic diseases such as HIV. Furthermore, little attention is paid to societal inclusion, community engagement and educational needs of these children. Integration of paediatric care and rehabilitation in a holistic approach can help to overcome the challenges associated with living disabilities. This scoping review proposes a synthesis of existing evidence on rehabilitation intervention strategies to increase functioning and to address disability-related barriers in children living with HIV and disability in sub-Saharan Africa. METHODS: A scoping review will be conducted to systematically map evidence on rehabilitation intervention for children living with HIV in sub-Saharan Africa. Studies in sub-Saharan Africa from December 2012 to 2019 on rehabilitation interventions for children aged 5 to 10 years living with HIV will be included in the review. Peer-reviewed primary studies, as well as grey literature, will be identified from electronic databases including Google Scholar; PubMed; Medline; CINAHL and Cochrane. The search strings using keywords such as "HIV", "impairment", "disability", "neurocognitive impairment", "behavioural", "rehabilitation" and "intervention" will be conducted using Boolean logic. Two groups of independent reviewers will conduct all title, abstract and full article screening. The study selection process will be mapped using Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. A predesigned data-charting table will supplement the extraction of data. NVIVO software will aide in the thematic analysis of the data. DISCUSSION: The information from studies will be discussed in relation to the research questions using a critical narrative to explore the emergent themes. The quality of studies will be appraised using the mixed method appraisal tool. The scoping review will provide a baseline of evidence on rehabilitation interventions for children living with HIV in sub-Saharan Africa. The scoping review will inform healthcare providers, scholars and policy developers about the current use of rehabilitation interventions and what gaps need to be addressed with further research and intervention development.

Common impairments and functional limitations of HIV sequelae that require physiotherapy rehabilitation in the medical wards at Queen Elizabeth Central Hospital, Malawi: A cross sectional study.

Introduction: The progression of human immunodeficiency virus (HIV) to acquired immune deficiency syndrome (AIDS) and the use of anti-retroviral therapy (ART) have resulted in a range of complications, which affect different body systems and result in functional limitations and disabling impairments. Objective: To investigate HIV-related impairments and functional limitations that require physiotherapy rehabilitation in patients admitted to the medical wards at Queen Elizabeth Central Hospital in Blantyre, Malawi. Methods: This was a descriptive quantitative cross-sectional study involving the participation of 32 female (59.3%) and 22 male (40.7%) adults living with HIV and admitted to the medical wards at Queen Elizabeth Central Hospital. We collected data using a questionnaire that consisted of the World Health Organization Disability Assessment Schedule 2 (WHODAS2.0) and some demographic questions. Results were analysed using the Statistical Package for the Social Sciences (SPSS). Results: Participation in society was the most frequently reported functional complication; the least common limitation was getting along with people (70.3%, n = 38 participants) and interaction with others (24%; n=13). Shortness of breath (55%; n=30), muscle weakness (44.4%; n=24) and joint and muscle pain (37%; n=20) were the most commonly reported impairments. Participation restriction in the society affected both males (77.3%) and females (70.7%). The least common limitation that required physiotherapy for both males and females was getting along with people (26.6% and 25%, respectively). On average, male and female participants had a disability severity score of 48.5±4.6 and 42.2±22.8, respectively. Conclusion: Our data showed that there is a clear need for early intervention to halt or delay the progression of complications to avoid severe disability; this is not only good for the patient but also for the socioeconomic state of the nation. Timely and full functional assessment, as well as referral of people living with HIV/AIDS for rehabilitation, is an important step forwards.

Perspectives on the HIV continuum of care among adult opioid users in New York City: a qualitative study.

BACKGROUND: Engagement in the HIV care continuum combined with office-based opioid treatment remains a cornerstone in addressing the intertwined epidemics of opioid use disorder (OUD) and HIV/AIDS. Factors influencing patient engagement with OUD and HIV care are complex and require further study. METHODS: In this qualitative study, in-depth interviews were conducted among 23 adult patients who use drugs (PWUD) in an inpatient detoxification program in New York City. The semi-structured interview guide elicited participant experiences with various phases of the HIV care continuum, including factors influencing access to HIV care, interactions with HIV and primary care providers, preferences around integrated care approaches for OUD and HIV, and barriers experienced beyond clinical settings which affected access to HIV care (e.g., insurance issues, transportation, cost, retrieving prescriptions from their pharmacy). Data collection and thematic analysis took place concurrently using an iterative process-based established qualitative research method. RESULTS: Respondents elicited high acceptability for integrated or co-located care for HIV and OUD in primary care. Factors influencing engagement in HIV care included (1) access to rapid point-of-care HIV testing and counseling services, (2) insurance coverage and costs related to HIV testing and receipt of antiretroviral therapy (ART), (3) primary care providers offering HIV care and buprenorphine, (4) illicit ART sales to pharmacies, (5) disruption in supplies of ART following admissions to inpatient detoxification or residential treatment programs, (6) in-person and telephone contact with peer support networks and clinic staff, (7) stigma, and (8) access to administrative support in primary care to facilitate reengagement with care following relapse, behavioral health services, transportation vouchers, and relocation from subsidized housing exposing patients to actively using peers. CONCLUSION: These findings suggest expanding clinical and administrative support in primary care for PWUDs with patient navigators, case managers, mobile health interventions, and peer support networks to promote linkage and retention in care.

Evaluation of a Community-Based Self-Management Program to Increase Access to Rehabilitation for People Living with HIV.

We qualitatively evaluated a novel educational program to help people living with HIV understand the role of rehabilitation, facilitate access to rehabilitation, and promote self-management of chronic disease in Canada. The program incorporated components of self-efficacy, client-centered care, peer education, and problem-based learning. Delivery of the community-engaged program was viewed as feasible and acceptable; however, a flexible delivery model was deemed important. Perceived learning was related to rehabilitation, advocacy, and taking responsibility for one's health. A co-leader model and access to online resources were strengths. Future work should assess the ability to apply advocacy knowledge and skills to access rehabilitation services.

Characterizing the disability experience among adults living with HIV: a structural equation model using the HIV disability questionnaire (HDQ) within the HIV, health and rehabilitation survey.

BACKGROUND: People aging with HIV can experience a variety of health challenges associated with HIV and multimorbidity, referred to as 'disability'. Our aim was to characterize the disability experience and examine relationships between dimensions of disability among adults living with HIV. METHODS: We performed a structural equation modeling analysis with data from the Canadian web-based HIV, Health and Rehabilitation Survey. We measured disability using the HIV Disability Questionnaire (HDQ), a patient-reported outcome (69 items) that measures presence, severity and episodic features of disability across six domains: 1) physical symptoms, 2) cognitive symptoms, 3) mental-emotional health symptoms, 4) difficulties carrying out day-to-day activities, 5) uncertainty and worrying about the future, and 6) challenges to social inclusion. We used HDQ severity domain scores to represent disability dimensions and developed a structural model to assess relationships between disability dimensions using path analysis. We determined overall model fit with a Root Mean Square Error of Approximation (RMSEA) of < 0.05. We classified path coefficients of ≥ 0.2-0.5 as a medium (moderate) effect and > 0.5 a large (strong) effect. We used Mplus software for the analysis. RESULTS: Of the 941 respondents, most (79%) were men, taking combination antiretroviral medications (90%) and living with two or more simultaneous health conditions (72%). Highest HDQ presence and severity scores were in the uncertainty domain. The measurement model had good overall fit (RMSEA= 0.04). Results from the structural model identified physical symptoms as a strong direct predictor of having difficulties carrying out day-to-day activities (standardized path coefficient: 0.54; p < 0.001) and moderate predictor of having mental-emotional health symptoms (0.24; p < 0.001) and uncertainty (0.36; p < 0.001). Uncertainty was a strong direct predictor of having mental-emotional health symptoms (0.53; p < 0.001) and moderate direct predictor of having challenges to social inclusion (0.38; p < 0.001). The relationship from physical and cognitive symptoms to challenges to social inclusion was mediated by uncertainty, mental-emotional health symptoms, and difficulties carrying out day-to-day activities (total indirect effect from physical: 0.22; from cognitive: 0.18; p < 0.001). CONCLUSIONS: Uncertainty is a principal dimension of disability experienced by adults with HIV. Findings provide a foundation for clinicians and researchers to conceptualize disability and identifying areas to target interventions.
