Couple-Based HIV Prevention in the United States: Advantages, Gaps, and Future Directions

This article presents an overview of couple-based HIV prevention research to date, advantages of using and core components of couple-based interventions, gaps in the current understanding of couple-based HIV prevention, status of dissemination research and the transportability of effective couple-based HIV prevention and treatment to real-world settings, and recommendations for future directions in couple-based prevention and treatment. Couple-based studies conducted among several populations—heterosexuals, men who have sex with men, and drug users—reported in the research literature were reviewed. Commonalities and limitations were noted in customary focus areas of the couple-based approaches: sexual and drug risk reduction, HIV testing behaviors, adherence to HIV treatment, and prevention of mother-to-child transmission. Couple-based intervention strategies have been rigorously tested and are a valuable addition to the arsenal of HIV prevention strategies. Immediate needs and opportunities include couple-based intervention strategies for prevention of HIV and other sexually transmitted infections among serodiscordant couples, couples who do not know their HIV status, and couples in whom both partners are HIV negative, but at risk of HIV infection. There is a particular need to develop couple-based intervention strategies for men who have sex with men and for drug-involved couples

Couple-Based HIV Prevention for Low-Income Drug Users From New York City: A Randomized Controlled Trial to Reduce Dual Risks

Objective: Dual threats of injection drug use and risky sexual practices continue to increase transmission of HIV and other sexually transmitted Infections (STIs) among drug-using couples in low-income communities in the United States. Two hypotheses were tested: (1) “intervention effect”—whether the HIV risk-reduction intervention provided to the couple or individual partners would be more efficacious in decreasing number of unprotected sexual acts and having a lower cumulative incidence of biologically confirmed STIs over the 12-month follow-up period compared with the attention control condition; and (2) “modality effect”—whether the HIV risk-reduction intervention would be more likely to decrease the number of unprotected sexual acts and have a lower cumulative STI incidence when delivered to a couple compared with the same intervention delivered to an individual. Design: Using a randomized controlled trial, 282 HIV-negative drug-using couples (564 individuals) were randomly assigned to receive either of the following: (1) couple-based risk reduction; (2) individual-based HIV risk reduction, or (3) couple-based wellness promotion, which served as an attention control condition. Results: Over 12-month follow-up, there was a 30% reduction in the incidence rate of unprotected acts of intercourse with the study partners compared with participants in the attention control arm. Moreover, over 12-month follow-up there was a 29% reduction in the same outcome in the couple arm compared with the individual arm with a 41% reduction at the 12-month follow-up. Conclusion: A couple-based approach that addresses drug and sexual risks and targets low-income active drug users may help curb the HIV epidemic

Enhancing Lay Counselor Capacity to Improve Patient Outcomes with Multimedia Technology

Multimedia technologies offer powerful tools to increase capacity of health workers to deliver standardized, effective, and engaging antiretroviral medication adherence counseling. Masivukeni—is an innovative multimedia-based, computer-driven, lay counselor-delivered intervention designed to help people living with HIV in resource-limited settings achieve optimal adherence. This pilot study examined medication adherence and key psychosocial outcomes among 55 non-adherent South African HIV+ patients, on antiretroviral therapy (ART) for at least 6 months, who were randomized to receive either Masivukeni or standard of care (SOC) counseling for ART non-adherence. At baseline, there were no significant differences between the SOC and Masivukeni groups on any outcome variables. At post-intervention (approximately 5–6 weeks after baseline), -clinic-based pill count adherence data available for 20 participants (10 per intervention arm) showed a 10 % improvement for—participants and a decrease of 8 % for SOC participants. Masivukeni participants reported significantly more positive attitudes towards disclosure and medication social support, less social rejection, and better clinic–patient relationships than did SOC participants. Masivukeni shows promise to promote optimal adherence and provides preliminary evidence that multimedia, computer-based technology can help lay counselors offer better adherence counseling than standard approaches

It's not just what you say: Relationships of HIV dislosure and risk reduction among MSM in the post-HAART era

In the post-HAART era, critical questions arise as to what factors affect disclosure decisions and how these decisions are associated with factors such as high-risk behaviors and partner variables. We interviewed 1,828 HIV-positive men who have sex with men (MSM), of whom 46% disclosed to all partners. Among men with casual partners, 41.8% disclosed to all of these partners and 21.5% to none. Disclosure was associated with relationship type, perceived partner HIV status and sexual behaviors. Overall, 36.5% of respondents had unprotected anal sex (UAS) with partners of negative/unknown HIV status. Of those with only casual partners, 80.4% had >1 act of UAS and 58% of these did not disclose to all partners. This 58% were more likely to self-identify as gay (versus bisexual), be aware of their status for <5 years and have more partners. Being on HAART, viral load and number of symptoms were not associated with disclosure. This study—the largest conducted to date of disclosure among MSM and one of the few conducted post-HAART—indicates that almost 1/5th reported UAS with casual partners without disclosure, highlighting a public health challenge. Disclosure needs to be addressed in the context of relationship type, partner status and broader risk-reduction strategies

Intricacies and inter-relationships between HIV disclosure and HAART: A qualitative study

This study aimed to understand whether and how highly active antiretroviral treatment (HAART) affects views and patterns of disclosure and how disclosure interacts with treatment decisions. One hundred and fifty-two HIV-positive adults (52 MSM, 56 women and 44 IDU men) from four US cities participated in two to three-hour, semi-structured interviews in 1998–99. Results indicate that HAART interacts with and shapes HIV disclosure issues in several ways. Medications may ‘out’ people living with HIV. Thus, in different settings (e.g. work, prisons, drug rehabs and public situations), some try to hide medications or modify dosing schedules, which can contribute to non-adherence, and affect sexual behaviours. Disclosure of HIV and/or HAART may also result in antagonism from others who hold negative attitudes and beliefs about HAART, potentially impeding adherence. Observable side effects of medications can also ‘out’ individuals. Conversely, medications may improve appearance, delaying or impeding disclosure. Some wait until they are on HAART and look ‘well’ before disclosing; some who look healthy as a result of medication deny being HIV-positive. Alternatively, HIV disclosure can lead to support that facilitates initiation of, and adherence to, treatment. HIV disclosure and adherence can shape one another in critical ways. Yet these interactions have been under-studied and need to be further examined. Interventions and studies concerning each of these domains have generally been separate, but need to be integrated, and the importance of relationships between these two areas needs to be recognized

Masivukeni: Development of a Multimedia Based Antiretroviral Therapy Adherence Intervention for Counselors and Patients in South Africa

Effective medical treatment for HIV/AIDS requires patients’ optimal adherence to antiretroviral therapy (ART). In resource-constrained settings, lack of adequate standardized counseling for patients on ART remains a significant barrier to adherence. Masivukeni (“Let’s Wake Up” in Xhosa) is an innovative multimedia-based intervention designed to help people living with HIV in resource-limited settings achieve and maintain high levels of ART adherence. Adapted from a couples-based intervention tested in the United States (US), Masivukeni was developed through community-based participatory research with US and South African partners and informed by Ewart’s Social Action Theory. Innovative computer-based multimedia strategies were used to translate a labor- and training-intensive intervention into one that could be readily and widely used by lay counselors with relatively little training with low-literacy patients. In this paper, we describe the foundations of this new intervention, the process of its development, and the evidence of its high acceptability and feasibility

Factors impacting antiretroviral therapy adherence among human immunodeficiency virus-positive adolescents in Sub-Saharan Africa: a systematic review

© 2018 The Royal Society for Public Health. Published by Elsevier Ltd. All rights reserved.Objectives: Eighty-two percent of human immunodeficiency virus (HIV)–positive adolescents live in Sub-Saharan Africa (SSA). Despite the availability of antiretroviral therapy (ART), adherence levels are suboptimal, leading to poor outcomes. This systematic review investigated factors impacting ART adherence among adolescents in SSA, including religious beliefs and intimate relationships. Methods: A systematic review was conducted between June and August 2016 using eight electronic databases, including Cochrane and PubMed. Published, ongoing and unpublished research, conducted in SSA from 2004 to 2016, was identified and thematic analysis was used to summarise findings. Results: Eleven studies from eight SSA countries, published in English between 2011 and 2016, reported on factors impacting ART adherence among adolescents living with HIV (ALHIV). Forty-four barriers and 29 facilitators to adherence were identified, representing a complex web of factors. The main barriers were stigma, ART side-effects, lack of assistance and forgetfulness. Facilitators included caregiver support, peer support groups and knowledge of HIV status. Conclusions: Stigma reflects difficult relations between ALHIV and their HIV-negative peers and adults. Most interventions target only those with HIV, suggesting a policy shift towards the wider community could be beneficial. Recommendations include engaging religious leaders and schools to change negative societal attitudes. Limitations of the review include the urban settings and recruitment of predominantly vertically infected participants in most included studies. Therefore, the findings cannot be extrapolated to ALHIV residing in rural locations or horizontally infected ALHIV, highlighting the need for further research in those areas.Peer reviewedFinal Accepted Versio

Implementation of a couple-based HIV prevention program: a cluster randomized trial comparing manual versus Web-based approaches

Background Despite great need, the number of HIV prevention implementation studies remains limited. The challenge for researchers, in this time of limited HIV services agency resources, is to conceptualize and test how to disseminate efficacious, practical, and sustainable prevention programs more rapidly, and to understand how to do so in the absence of additional agency resources. We tested whether training and technical assistance (TA) in a couple-based HIV prevention program using a Web-based modality would yield greater program adoption of the program compared to training and TA in the same program in a manual-based modality among facilitators who delivered the interventions at 80 agencies in New York State. Methods This study used a cluster randomized controlled design. Participants were HIV services agencies (N = 80) and up to 6 staff members at each agency (N = 253). Agencies were recruited, matched on key variables, and randomly assigned to two conditions. Staff members participated in a four-day, face-to-face training session, followed by TA calls at two and four months, and follow-up assessments at 6, 12, and 18 months post- training and TA. The primary outcomes examined number of couples with whom staff implemented the program, mean number of sessions implemented, whether staff implemented at least one session or whether staff implemented a complete intervention (all six sessions) of the program. Outcomes were measured at both the agency and participant level. Results Over 18 months following training and TA, at least one participant from 13 (33%) Web-based assigned agencies and 19 (48%) traditional agencies reported program use. Longitudinal multilevel analysis found no differences between groups on any outcomes at the agency or participant level with one exception: Web-based agencies implemented the program with 35% fewer couples compared with staff at manual-based agencies (IRR 0.35, CI, 0.13-0.94). Conclusion Greater implementation of a Web-based program may require more resources and staff exposure, especially when paired with a couple-based modality. Manual-based and traditional programs may hold some advantage or ease for implementation, particularly at a time of low economic resources

A model for adapting evidence-based behavioral interventions to a new culture: HIV prevention for psychiatric patients in Rio de Janeiro, Brazil

As in other countries worldwide, adults with severe mental illness in Brazil have elevated rates of HIV infection relative to the general population. However, no HIV prevention interventions have been tested for efficacy with psychiatric patients in Brazil. We conducted participatory research with local providers, community leaders, patient advocates, and patients using an intervention adaptation process designed to balance fidelity to efficacious interventions developed elsewhere with fit to a new context and culture. Our process for adapting these interventions comprised four steps: (1) optimizing fidelity; (2) optimizing fit; (3) balancing fidelity and fit; and (4) pilot testing and refining the intervention. This paper describes how these steps were carried out to produce a Brazilian HIV prevention intervention for people with severe mental illness. Our process may serve as a model for adapting existing efficacious interventions to new groups and cultures, whether at a local, national, or international level

Psychiatric Context of Acute/Early HIV Infection. The NIMH Multisite Acute HIV Infection Study: IV

Acute/early HIV infection is a period of high risk for HIV transmission. Better understanding of behavioral aspects during this period could improve interventions to limit further transmission. Thirty-four participants with acute/early HIV infection from six US cities were assessed with the Mini International Diagnostic Interview, Beck Depression Inventory II, State-Trait Anxiety Inventory, Brief COPE, and an in-depth interview. Most had a pre-HIV history of alcohol or substance use disorder (85%); a majority (53%) had a history of major depressive or bipolar disorder. However, post-diagnosis coping was predominantly adaptive, with only mild to moderate elevations of anxious or depressive mood. Respondents described challenges managing HIV in tandem with pre-existing substance abuse problems, depression, and anxiety. Integration into medical and community services was associated with adaptive coping. The psychiatric context of acute/early HIV infection may be a precursor to infection, but not necessarily a barrier to intervention to reduce forward transmission of HIV among persons newly infected
