Suicidal thoughts and behaviours in Cape Town
Open AccessMpho Tlali, Reshma Kassanjee et al.ARTICLESSM - Mental Health2026
Suicidal thoughts and behaviours (STBs) are traditionally attributed to mental disorders; however, increasing evidence indicates that social determinants contribute to suicide risk. We examined STBs and their socioeconomic, psychosocial and clinical correlates in two communities in Cape Town. We conducted psychiatric diagnostic interviews (MINI) at three public-sector facilities (2023-2024). Adults aged ≥18 years, with and without HIV, were recru…
Cost-effectiveness of a peer-delivered behavioral intervention for adherence to antiretroviral therapy and alcohol and drug use in South African HIV care
Thanh Lu, Jennifer M Belus et al.ARTICLEAIDS Care2026
Cost-effective approaches for integrating behavioral interventions for problematic alcohol and other drug (AOD) use into HIV care is needed, as problematic AOD is a primary barrier to adherence of antiretroviral therapy (ART). Thus, we investigated the cost-effectiveness of a recently completed pilot trial in South Africa, that showed promising findings in improved adherence of antiretroviral therapy (ART). The trial compared a task-shared, peer-…
Factors associated with driving simulator performance in vocational drivers with HIV
Open AccessHetta Gouse, Michelle Henry et al.ARTICLEAIDS Care2025
Neurocognitive symptoms persist in many people living with HIV (PLWH). Safe driving practices are dependent on intact cognition. Research in the general driving population suggests that PLWH with neurocognitive impairment (NCI) perform worse on driving assessment tasks than cognitively intact PLWH. We explored the relationship between HIV status, NCI, and driving ability in vocational drivers. Two-hundred-and-four male drivers [68 drivers with HI…
Attitudes toward digital pill systems for antiretroviral therapy adherence among pregnant and postpartum women living with HIV in South Africa
Open AccessMadison R Fertig, Jasper S Lee et al.ARTICLEFrontiers in Psychiatry2025
Future research should explore ideal Reader systems to facilitate use among this population in SA, especially among persons who report low ART adherence or have unsuppressed HIV RNA when presenting for antenatal care
I’ll Continue If I Have a Positive Mind”
Open AccessAmelia M Stanton, Madison R Fertig et al.ARTICLEInternational Journal of…2025
Pregnant and postpartum people (PPPs) face heightened risk for HIV acquisition, yet depression and trauma-related symptoms can undermine adherence to pre-exposure prophylaxis (PrEP). To inform the development of a brief mental health-focused adherence intervention, we explored the impacts of depression and posttraumatic stress disorder (PTSD) symptoms on PrEP use among PPPs in Cape Town, South Africa. Twenty-eight PPPs with elevated symptoms of d…
The Factorial Structure, Reliability, and Validity of a Coping Measure Among Women with HIV and Sexual Trauma in Cape Town, South Africa
Open AccessStephan Rabie, Anubhuti Poudyal et al.ARTICLEAIDS and Behavior2025
The dual epidemics of HIV and sexual violence against women complicate HIV care engagement in South Africa. In settings with limited mental health treatment, robust measures to enhance screening and intervention for mental health specific to people with HIV are needed. The current study developed a 42-item assessment for coping with HIV and trauma in isiXhosa. In a randomized controlled trial, 350 participants completed measures of coping, anxiet…
Piloting Siyakhana
Open AccessKristen S Regenauer, Alexandra L Rose et al.ARTICLEPLOS Global Public Health2024
South Africa has one of the highest rates of HIV/tuberculosis (TB) co-infection, and poor engagement in HIV/TB care contributes to morbidity and mortality. In South Africa, community health workers (CHWs) are tasked with re-engaging patients who have dropped out of HIV/TB care. CHWs have described substantial challenges with substance use (SU) and depression among their patients, while patients have described CHW stigma towards SU and depression …
The salience of structural barriers and behavioral health problems to ART adherence in people receiving HIV primary care in South Africa
Steven A Safren, Jasper S Lee et al.ARTICLEAIDS Care2024
Multilevel factors (individual and structural) influence adherence to antiretroviral therapy, particularly in high HIV prevalence areas such as South Africa. The present study examined the relative importance of structural barriers to HIV care and behavioral health factors, depression and alcohol use, in Khayelitsha, Cape Town, South Africa. People receiving HIV care in six primary care clinics in Khayelitsha (N = 194) completed the Center for Ep…

Mental and cognitive healthcare training targeting primary healthcare workers providing HIV services in Africa
Adele Munsami, Anna J Dreyer et al.ARTICLEAIDS Care2023
Mental health and neurocognitive functioning remain a concern among people living with HIV. Symptomatic neurocognitive impairment (NCI) and mental illness can cause difficulties in daily functioning, including problems adhering to treatment. However, many healthcare workers in resource-limited settings have limited knowledge about the relationship between HIV and NCI. A synthesis of available literature on mental health and NCI training provided …

Mental Health, ART Adherence, and Viral Suppression Among Adolescents and Adults Living with HIV in South Africa
Open AccessAndreas D Haas, Raphael Lienhard et al.ARTICLEAIDS and Behavior2023
We followed adolescents and adults living with HIV aged older than 15 years who enrolled in a South African private-sector HIV programme to examine adherence and viral non-suppression (viral load > 400 copies/mL) of participants with (20,743, 38%) and without (33,635, 62%) mental health diagnoses. Mental health diagnoses were associated with unfavourable adherence patterns. The risk of viral non-suppression was higher among patients with organic …
Cognitive Performance, as well as Depression, Alcohol Use, and Gender, predict Anti-Retroviral Therapy Adherence in a South African Cohort of People with HIV and Comorbid Major Depressive Disorder
Open AccessAnna J Dreyer, Sam Nightingale et al.ARTICLEAIDS and Behavior2023
Depression and cognitive impairment, which commonly coexist in people with HIV (PWH), have been identified as potential barriers to optimal antiretroviral therapy (ART) adherence. We investigated associations between cognitive performance, depression (as well as other sociodemographic, psychosocial and psychiatric variables) and ART adherence in a South African cohort of PWH with comorbid major depressive disorder (MDD). Cognitive performance and…
Exploring HIV-Associated Neurocognitive Impairment in the Era of Effective Antiretroviral Therapy
Open AccessAdele Munsami, J I Falconer et al.ARTICLEQualitative Health Research2022
The prevalence of HIV-associated neurocognitive impairment (H-NCI) is concerning. Individuals on effective antiretroviral therapy (ART) may still be at risk for H-NCI as they experience longer life expectancies. There are, however, few professionals with knowledge and skills to identify H-NCI, in low- and middle-income countries. We explored qualitatively, primary healthcare workers’ knowledge and views of H-NCI, in the era of effective ART, part…
The combination of HIV and alcohol use internalized stigmas are associated with greater symptoms of depression in a South African sample living with HIV
Open AccessMorgan S Anvari, Jennifer M Belus et al.ARTICLEStigma and Health2022
Approximately one-third of people living with human immunodeficiency virus (HIV) in South Africa (SA) present to HIV care with unhealthy alcohol use (UA); depression is highly prevalent among this population. Internalized HIV and UA stigma have been associated with greater depressive symptoms when examined in isolation. Yet, prior research has rarely examined how internalized HIV and UA stigmas together relate to depressive symptoms and related o…
Patient and provider perceptions of a peer-delivered intervention (‘ Khanya ’) to improve anti-retroviral adherence and substance use in South Africa
Open AccessAlexandra L Rose, Jennifer M Belus et al.ARTICLECambridge Prisms Global Mental…2022
Findings underscore the importance of examining patients' perspectives on specific intervention components within intervention packages. While mindfulness training and peer delivery models were positively perceived by consumers, they are rarely used within task-shared behavioral interventions in low- and middle-income countries

Gender Moderates Results of a Randomized Clinical Trial for the Khanya Intervention for Substance Use and ART Adherence in HIV Care in South Africa
Open AccessJennifer M Belus, John A Joska et al.ARTICLEAIDS and Behavior2022
Little is known about gender effects of alcohol and drug use (AOD) among people living with HIV (PLWH) in resource-limited settings. Using multilevel models, we tested whether gender moderated the effect of Khanya, a cognitive-behavioral therapy-based intervention addressing antiretroviral (ART) adherence and AOD reduction. We enrolled 61 participants from HIV care and examined outcomes at 3- and 6-months compared to enhanced treatment as usual (…

Sociodemographic and psychosocial predictors of longitudinal antiretroviral therapy (ART) adherence among first-time ART initiators in Cape Town, South Africa
Alissa Davis, Andrea Norcini Pala et al.ARTICLEAIDS Care2021
First-time antiretroviral therapy (ART) initiators may be more vulnerable to poor ART adherence because they may be coping with a new HIV diagnosis, facing logistical challenges to accessing and adhering to ART for the first time, and have not yet developed support networks or the skills to support long-term adherence. We recruited 324 participants in two HIV clinics near Cape Town, South Africa. Sociodemographic/psychosocial factors were measure…
Factors associated with external HIV-related stigma and psychological distress among people living with HIV in South Africa
Open AccessNolusindiso Ncitakalo, Musawenkosi Mabaso et al.ARTICLESSM - Population Health2021
The findings suggest a need to reinvigorate stigma-reduction interventions in the national HIV response with emphasis on HIV awareness and education campaigns. In addition, HIV testing services should be reinforced through communication strategies targeted against HIV stigmatization, discrimination and fear. There is also a need to continuously engage PLHIV in programs through counselling and support interventions for acceptance of HIV positive s…
Associations Between Patterns of Alcohol Use and Viral Load Suppression Amongst Women Living with HIV in South Africa
Open AccessBronwyn Myers, Chantal Lombard et al.ARTICLEAIDS and Behavior2021
This study aimed to identify alcohol use patterns associated with viral non-suppression among women living with HIV (WLWH) and the extent to which adherence mediated these relationships. Baseline data on covariates, alcohol consumption, ART adherence, and viral load were collected from 608 WLWH on ART living in the Western Cape, South Africa. We defined three consumption patterns: no/light drinking (drinking ≤ 1/week and ≤ 4 drinks/occasion), occ…

Improving the measurement of food insecurity among people with HIV in South Africa
Open AccessJasper S Lee, Cengiz Zopluoglu et al.ARTICLEPublic Health Nutrition2021
Objective: Food insecurity is a structural barrier to HIV care in peri-urban areas in South Africa (SA), where approximately 80 % of households are moderately or severely food insecure. For people with HIV (PWH), food insecurity is associated with poor antiretroviral therapy adherence and survival rates. Yet, measurement of food insecurity among PWH remains a challenge. Design: The current study examines the factor structure of the nine-item Hous…
