    INTRODUCTION: Screening, Brief Interventions and Referral to Treatment (SBIRT) programs reduce unhealthy alcohol use among adolescents. However, self-report screening alone may lead to false negatives and low service use, especially in HIV care settings. This study explored the contextual implementation factors and strategies of an alcohol biomarker-augmented SBIRT program for HIV-affected adolescents in Zambia, where alcohol use and HIV prevalence are high. METHODS: We conducted key informant interviews (n=7) with mental health providers and policymakers and focus groups (n=16 groups; 10-11 participants each) with healthcare providers, adolescents, and caregivers, guided by a case vignette of the biomarker-augmented SBIRT program. Thematic analysis followed the implementation frameworks Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) and Practical, Robust Implementation and Sustainability Model (PRISM). RESULTS: Participants perceived the SBIRT program as appropriate for adolescent alcohol use. Key contextual factors included: lack of alcohol treatment programs, community stigma against HIV and alcohol use, and robust implementation infrastructure through HIV healthcare. Strategies to enhance acceptability included making alcohol screening universal to avoid labeling adolescents, privacy and confidentiality during biomarker sampling, and peer-led age-matched counseling at screening. To enhance reach, participants suggested designing the program with attention to gender-specific needs and integrating it into HIV healthcare and alcohol use hotspots (e.g. schools). CONCLUSIONS: Implementation strategies should be designed to reduce stigma, build trust, engage adolescents across genders, and reach youth through clinical and community channels. Future research should define how to select, train, and evaluate peer counselors and assess the effectiveness of alcohol biomarkers within SBIRT programs in motivating behavior change.

    Efficacy of the Common Elements Treatment Approach (CETA) for Unhealthy Alcohol Use Among Adults with HIV in Zambia: Results from a Pilot Randomized Controlled Trial.
    (2022-Feb) Kane, Jeremy C.; Sharma, Anjali; Murray, Laura K.; Chander, Geetanjali; Kanguya, Tukiya; Skavenski, Stephanie; Chitambi, Chipo; Lasater, Molly E.; Paul, Ravi; Cropsey, Karen; Inoue, Sachi; Bosomprah, Samuel; Danielson, Carla K.; Chipungu, Jenala; Simenda, Francis; Vinikoor, Michael J.
    This randomized controlled trial tested the efficacy of a multi-session, evidence-based, lay counselor-delivered transdiagnostic therapy, the Common Elements Treatment Approach (CETA), in reducing unhealthy alcohol use and comorbidities among persons living with HIV (PLWH) in Zambia. Adult PLWH with (a) unhealthy alcohol use plus mental health or substance use comorbidities, or (b) severe unhealthy alcohol use were randomized to receive a single-session alcohol brief intervention (BI) alone or BI plus referral to CETA. Outcomes were measured at baseline and a 6-month follow-up and included Alcohol Use Disorders Identification Test (AUDIT) score (primary), depression and trauma symptoms, and other substance use (secondary). We enrolled 160 participants; 78 were randomized to BI alone and 82 to BI plus CETA. Due to COVID-19, the trial ended early before 36 participants completed. Statistically and clinically significant reductions in mean AUDIT score from baseline to 6-month follow-up were observed in both groups, however, participants assigned to BI plus CETA had significantly greater reductions compared to BI alone (- 3.2, 95% CI - 6.2 to - 0.1; Cohen's d: 0.48). The CETA effect size for AUDIT score increased in line with increasing mental health/substance use comorbidity (0 comorbidities d = 0.25; 1-2 comorbidities d = 0.36; 3+ comorbidities d = 1.6). Significant CETA treatment effects were observed for depression, trauma, and several other substances. BI plus referral to CETA was feasible and superior to BI alone for unhealthy alcohol use among adults with HIV, particularly among those with comorbidities. Findings support future effectiveness testing of CETA for HIV outcomes among PLWH with unhealthy alcohol use.Clinical Trials Number: NCT03966885.
