RESUMEN

We used results from an optimization randomized controlled trial which tested five behavioral intervention components to support HIV antiretroviral adherence/HIV viral suppression, grounded in the multiphase optimization strategy and using a fractional factorial design to identify intervention components with cost-effectiveness sufficiently favorable for scalability. Results were incorporated into a validated HIV computer simulation to simulate longer-term effects of combinations of components on health and costs. We simulated the 32 corresponding long-term trajectories for viral load suppression, health related quality of life (HRQoL), and costs. The components were designed to be culturally and structurally salient. They were: motivational interviewing counseling sessions (MI), pre-adherence skill building (SB), peer mentorship (PM), focused support groups (SG), and patient navigation (short version [NS], long version [NL]. All participants also received health education on HIV treatment. We examined four scenarios: one-time intervention with and without discounting and continuous interventions with and without discounting. In all four scenarios, interventions that comprise or include SB and NL (and including health education) were cost effective (< $100,000/quality-adjusted life year). Further, with consideration of HRQoL impact, maximal intervention became cost-effective enough to be scalable. Thus, a fractional factorial experiment coupled with cost-effectiveness analysis is a promising approach to optimize multi-component interventions for scalability. The present study can guide service planning efforts for HIV care settings and health departments.

RESUMEN

BACKGROUND: People who inject drugs living with HIV (PWIDLH) suffer the lowest rates of HIV viral suppression due to episodic injection drug use and poor mental health coupled with poor retention in HIV care. Approximately 44% of PWIDLH along the US-Mexico border are retained in care and only 24% are virally suppressed. This underserved region faces a potential explosion of transmission of HIV due to highly prevalent injection drug use. This protocol describes an optimization trial to promote sustained viral suppression among Spanish-speaking Latinx PWIDLH. METHODS: The multiphase optimization strategy (MOST) is an engineering-inspired framework for designing and building optimized interventions and guides this intervention. The primary aim is to conduct a 24 factorial experiment in which participants are randomized to one of 16 intervention conditions, with each condition comprising a different combination of four behavioral intervention components. The components are peer support for methadone uptake and persistence; behavioral activation therapy for depression; Life-Steps medication adherence counseling; and patient navigation for HIV care. Participants will complete a baseline survey, undergo intervention, and then return for 3-,6-,9-, and 12-month follow-up assessments. The primary outcome is sustained viral suppression, defined as viral loads of < 40 copies per mL at 6-,9-, and 12-month follow-up assessments. Results will yield effect sizes for each component and each additive and interactive combination of components. The research team and partners will make decisions about what constitutes the optimized multi-component intervention by judging the observed effect sizes, interactions, and statistical significance against real-world implementation constraints. The secondary aims are to test mediators and moderators of the component-to-outcome relationship at the 6-month follow-up assessment. DISCUSSION: We are testing well-studied and available intervention components to support PWIDLH to reduce drug use and improve their mental health and engagement in HIV care. The intervention design will allow for a better understanding of how these components work in combination and can be optimized for the setting. TRIAL REGISTRATION: This project was registered at clinicaltrials.gov (NCT05377463) on May 17th, 2022.

RESUMEN

We conducted a novel pilot randomized controlled trial of the Treatment Ambassador Program (TAP), an 8-session, peer-based, behavioral intervention for people with HIV (PWH) in South Africa not on antiretroviral therapy (ART). PWH (43 intervention, 41 controls) completed baseline, 3- and 6-month assessments. TAP was highly feasible (90% completion), with peer counselors demonstrating good intervention fidelity. Post-intervention interviews showed high acceptability of TAP and counselors, who supported autonomy, assisted with clinical navigation, and provided psychosocial support. Intention-to-treat analyses indicated increased ART initiation by 3 months in the intervention vs. control arm (12.2% [5/41] vs. 2.3% [1/43], Fisher exact p-value = 0.105; Cohen's h = 0.41). Among those previously on ART (off for > 6 months), 33.3% initiated ART by 3 months in the intervention vs. 14.3% in the control arm (Cohen's h = 0.45). Results suggest that TAP was highly acceptable and feasible among PWH not on ART.

RESUMEN

It is estimated that one in six Black and Latino adult persons living with HIV (PLWH) spend time in correctional institutions each year. Yet after release, PLWH of color evidence poor HIV health outcomes across the HIV care continuum. This study, guided by an ecological approach and Critical Race Theory, sought to understand the lived experiences of socioeconomically disadvantaged PLWH of color who received an HIV diagnosis and/or medical care while incarcerated, and the ways in which those experiences influenced engagement in medical care after release. Drawn from a larger study in Brooklyn, NY, in 2013-2016, a subset of 28 participants who received in-depth qualitative interviews were purposively sampled for a secondary analysis of participants who received an HIV diagnosis and/or medical care while incarcerated. Using an Interpretive Phenomenological Analysis, we found participant's experiences were shaped by longstanding mistrust of the medical establishment. While incarcerated, lack of autonomy, substandard medical care, and poor social support exacerbated medical mistrust and avoidance of HIV medical care long after release. Engagement in HIV medical care and treatment were also impacted by a dynamic interplay of factors including substance use, prolonged periods of denial, poverty, and repeated bouts of incarceration. Given that experiences of HIV diagnosis and medical care while incarcerated have long-ranging, adverse effects, we argue that a better understanding of the ways in which PLWH of color experience HIV diagnosis and medical care while incarcerated may serve to inform intervention efforts within correctional institutions to improve HIV health outcomes.

RESUMEN

BACKGROUND: The problem of injection drug use in public bathrooms has been documented from the perspectives of people who inject drugs and service industry employees (SIEs). Previous studies suggest that SIEs are unaware of how to respond to opioid overdoses, yet there are no behavioral interventions designed for SIEs to address their specific needs. In response to this gap in the field, we constructed, implemented, and evaluated a three-module behavioral intervention for SIEs grounded in the Information-Motivation-Behavioral skills model. This paper focuses on the evaluation of one module, namely, the intervention component addressing overdose response and naloxone administration (ORNA). METHODS: Participants were SIEs (N = 18 from two separate business establishments) recruited using convenience sampling. The study utilized a pre-/post-test concurrent nested mixed method design and collected quantitative and qualitative data including an evaluation of the intervention module. The primary outcomes were opioid overdose-related knowledge and attitudes. Acceptability was also assessed. RESULTS: SIEs demonstrated significant improvements (p < 0.01, Cohen's d = 1.45) in opioid overdose-related knowledge as well as more positive opioid overdose-related attitudes (p< 0.01, Cohen's d = 2.45) following the intervention. Participants also reported high levels of acceptability of the module and suggestions for improvement (i.e., more role-playing). CONCLUSIONS: This study highlights the acceptability and evidence of efficacy of the ORNA module, as well as the utility of training SIEs in ORNA. The expansion of this training to other SIEs and public employees (librarians, etc.) who manage public bathrooms warrants further investigation.

RESUMEN

INTRODUCTION: We used a computer simulation of HIV progression and transmission to evaluate the cost-effectiveness of a scale-up of 3 strategies to seek out and test individuals with undiagnosed HIV in New York City (NYC). SETTING: Hypothetical NYC population. METHODS: We incorporated the observed effects and costs of the 3 "seek and test" strategies in a computer simulation of HIV in NYC, comparing a scenario in which the strategies were scaled up with a 1-year implementation or a long-term implementation with a counterfactual scenario with no scale-up. The simulation combined a deterministic compartmental model of HIV transmission with a stochastic microsimulation of HIV progression, calibrated to NYC epidemiological data from 2003 to 2015. The 3 approaches were respondent-driven sampling (RDS) with anonymous HIV testing ("RDS-A"), RDS with a 2-session confidential HIV testing approach ("RDS-C"), and venue-based sampling ("VBS"). RESULTS: RDS-A was the most cost-effective strategy tested. When implemented for only 1 year and then stopped thereafter, using a societal perspective, the cost per quality-adjusted life-year (QALY) gained versus no intervention was $812/QALY, $18,110/QALY, and $20,362/QALY for RDS-A, RDS-C, and VBS, respectively. When interventions were implemented long term, the cost per QALY gained versus no intervention was cost-saving, $31,773/QALY, and $35,148/QALY for RDS-A, RDS-C, and VBS, respectively. When compared with RDS-A, the incremental cost-effectiveness ratios for both VBS and RDS-C were dominated. CONCLUSIONS: The expansion of the RDS-A strategy would substantially reduce HIV-related deaths and new HIV infections in NYC, and would be either cost-saving or have favorable cost-effectiveness.

RESUMEN

Organizations for runaway and homeless youth (RHY) provide essential services to highly vulnerable youth who have a wide variety of basic needs and complex psychosocial challenges. We present a mixed-methods case study of an RHY organization to identify the specific mechanisms and processes by the organization successfully promotes engagement and positive development of the youth they serve. We analyzed the qualitative and quantitative data separately and then integrated these two strands of data. Our findings indicate a consistent convergence of responses across the data sources, in both the qualitative and quantitative strands, that consistently reflect the organization's youth-centered approach. Primary among these policies and practices is the emphasis on building and maintaining empathic relationships with youth, the promotion of youths' autonomy, and an institutional culture of continuous evaluation of how the organization is meeting their mission to provide services that reflect best practices.

RESUMEN

PURPOSE: Assertive communication has been associated with higher levels of condom use among youth using self-report survey methodology. The purpose of this study was to examine the subjective ratings of assertiveness among young, romantically involved couples in the context of a condom negotiation task. METHODS: Using an innovative video-recall procedure, 32 couples (64 youth) engaged in a videotaped condom negotiation task and then rated self and partners' level of assertiveness. Both individual ratings of assertiveness and couple-level assertiveness were assessed using dyadic hierarchical linear modeling. RESULTS: Individuals' assertiveness was positively associated with condom use. Unexpectedly, the overall level of assertiveness in couples showed a curvilinear association with condom use. Very high and very low assertiveness was associated with lower condom use, whereas moderate levels of assertiveness were associated with higher condom use. CONCLUSIONS: Moderate levels of assertiveness during condom negotiation may facilitate condom use in young couples. Increasing condom use among romantic partners may require developing interventions that strengthen youths' ability to engage in assertive communication strategies that balance emotional intimacy with self-advocacy.

RESUMEN

There is growing awareness that students' experiences of stress may impede academic success, compromise mental health, and promote substance use. We examined these factors in an under-studied population, private/independent high school students, using a multi-method (qualitative and quantitative), iterative data collection and analytic process. We first conducted qualitative interviews with faculty and staff at a number of highly competitive private schools, followed by an anonymous quantitative survey with 128 11th grade students from two of these settings. We then conducted a qualitative exploration of the quantitative results with a subset of students. Next, a set of Expert Panel members participated in qualitative interviews to reflect on and interpret study findings. Overall, we found students experienced high levels of chronic stress, particularly in relation to academic performance and the college admissions process. While students described a range of effective, adaptive coping strategies, they also commonly internalized these serious pressures and turned to alcohol and drugs to cope with chronic stress, although not typically at problematic levels. We discuss study implications for both schools and families derived from the Expert Panel.

RESUMEN

The heightened level of risk for HIV infection among Black and Latino young men who have sex with men (YMSM) is driven by multilevel influences. Using cross-sectional data, we examined HIV testing patterns among urban YMSM of color in a high-HIV seroprevalence area (ages 16 to 21 years). Self-reported frequency of testing was high, with 42% of youth reporting testing at a greater frequency than recommended guidelines. There were no differences between less frequent and more frequent testers on sexual risk behaviors. Most (80%) youth cited reassurance of HIV-negative status as a reason for testing. Further, over half of the sample reported numerous other reasons for HIV testing, which spanned individual, partner, social, and structural levels of influence. Approximately half of respondents indicated that peers, family members, and counselors influenced their motivation to get tested. Of concern, their first HIV test occurred approximately 2 years after their first sexual experience with another male. These results indicate the need to consider developmental issues as well as comprehensive, multilevel efforts to ensure that YMSM of color test at the Centers for Disease Control and Prevention-recommended frequency but not less than this or too frequently.

RESUMEN

We investigated the impact of cognitive behavioral therapy and mindfulness training (CBT/MT) on attentional task performance in incarcerated adolescents. Attention is a cognitive system necessary for managing cognitive demands and regulating emotions. Yet persistent and intensive demands, such as those experienced during high-stress intervals like incarceration and the events leading to incarceration, may deplete attention resulting in cognitive failures, emotional disturbances, and impulsive behavior. We hypothesized that CBT/MT may mitigate these deleterious effects of high stress and protect against degradation in attention over the high-stress interval of incarceration. Using a quasi-experimental, group randomized controlled trial design, we randomly assigned dormitories of incarcerated youth, ages 16-18, to a CBT/MT intervention (youth n = 147) or an active control intervention (youth n = 117). Both arms received approximately 750 min of intervention in a small-group setting over a 3-5 week period. Youth in the CBT/MT arm also logged the amount of out-of-session time spent practicing MT exercises. The Attention Network Test was used to index attentional task performance at baseline and 4 months post-baseline. Overall, task performance degraded over time in all participants. The magnitude of performance degradation was significantly less in the CBT/MT vs. control arm. Further, within the CBT/MT arm, performance degraded over time in those with no outside-of-class practice time, but remained stable over time in those who practiced mindfulness exercises outside of the session meetings. Thus, these findings suggest that sufficient CBT/MT practice may protect against functional attentional impairments associated with high-stress intervals.
