Item Effectiveness of trauma-focused cognitive behavioral therapy compared to psychosocial counseling in reducing HIV risk behaviors, substance use, and mental health problems among orphans and vulnerable children in Zambia: a community-based randomized controlled trial.(2024-Jan) Kane JC; Figge C; Paniagua-Avila A; Michaels-Strasser S; Akiba C; Mwenge M; Munthali S; Bolton P; Skavenski S; Paul R; Simenda F; Whetten K; Cohen J; Metz K; Murray LK; School of Medicine, University of Zambia, University Teaching Hospital, Lusaka, Zambia.; Zambia Ministry of Health, Lusaka, Zambia.; Drexel University College of Medicine, Allegheny Health Network/Allegheny General Hospital, Pittsburgh, PA, USA.; Department of Mental Health, Johns Hopkins Bloomberg School of Public Health, Baltimore, MD, USA.; Duke Global Health Instittute, Durham, NC, USA.; Department of Health Behavior, University of North Carolina Gillings School of Public Health, Chapel Hill, NC, USA.; Department of Mental Health, Johns Hopkins Bloomberg School of Public Health, Baltimore, MD, USA. jk4397@cumc.columbia.edu.; Center for Health Policy and Inequalities Research, Durham, NC, USA.; Duke Sanford School of Public Policy, Durham, NC, USA.; Centre for Infectious Disease Research in Zambia, Lusaka, Zambia.; Department of Epidemiology, Columbia University Mailman School of Public Health, New York, NY, USA.; ICAP, Columbia University Mailman School of Public Health, New York, NY, USA.; Department of Epidemiology, Columbia University Mailman School of Public Health, New York, NY, USA. jk4397@cumc.columbia.edu.; CIDRZ; Centre for Infectious Disease Research in Zambia (CIDRZ)Orphans and vulnerable children (OVC) in sub-Saharan Africa are at high risk for HIV infection and transmission. HIV prevention and treatment efforts with OVC are hindered by mental health and substance use problems. This randomized controlled trial compared a mental health intervention, Trauma Focused Cognitive Behavioral Therapy (TF-CBT), to an enhanced version of an existing HIV Psychosocial Counseling (PC+) program among 610 adolescents who met PEPFAR criteria for OVC and had HIV risk behaviors in Lusaka, Zambia. Outcomes included HIV risk behaviors (e.g., risky sexual behaviors), mental health (internalizing symptoms, externalizing behaviors, PTSD) and substance use. At 12-month follow-up, there were significant within group reductions in both groups for all outcomes, with the only significant between group difference being for substance use, in which OVC who received TF-CBT had significantly greater reductions than OVC who received PC+. In a subgroup analysis of OVC with high levels of PTSD symptoms, TF-CBT was superior to PC + in reducing internalizing symptoms, functional impairment, and substance use. Findings support TF-CBT for reducing substance use among OVC. Subgroup analysis results suggest that a robust intervention such as TF-CBT is warranted for OVC with significant mental and behavioral health comorbidities. The similar performance of TF-CBT and PC + in the overall sample for risky sexual behavior and mild mental health problems indicates that enhancing existing psychosocial programs, such as PC, with standard implementation factors like having a defined training and supervision schedule (as was done to create PC+) may improve the efficacy of HIV risk reduction efforts.Clinical Trials Number: NCT02054780.Item Testing the validity of the AUDIT-C and AUDIT-3 to detect unhealthy alcohol use among high-risk populations in Zambia: A secondary analysis from two randomized trials.(2021-Dec-01) Inoue S; Chitambi C; Vinikoor MJ; Kanguya T; Murray LK; Sharma A; Chander G; Paul R; Mwenge MM; Munthali S; Kane JC; University of Alabama at Birmingham School of Medicine, Birmingham, AL, USA.; Department of Mental Health, Johns Hopkins Bloomberg School of Public Health, Baltimore, MD, USA.; University of Zambia School of Medicine, Lusaka, Zambia.; Johns Hopkins University School of Medicine, Baltimore, MD, USA.; Centre for Infectious Disease Research in Zambia (CIDRZ), Lusaka, Zambia.; Department of Epidemiology, Columbia University Mailman School of Public Health, New York, NY, USA.; Department of Epidemiology, Columbia University Mailman School of Public Health, New York, NY, USA. Electronic address: sachi_inoue@hsph.harvard.edu.BACKGROUND: This study evaluated the test characteristics of brief versions of the Alcohol Use Disorders Identification Test (AUDIT), the AUDIT-C and AUDIT-3, compared to the full AUDIT in populations with heavy drinking living in Zambia and compared differences in effect size estimates when using brief versions in clinical trials. METHODS: Data were obtained from two randomized trials of the Common Elements Treatment Approach (CETA) for reducing unhealthy alcohol use among adult couples and people living with HIV (PLWH) in Zambia. The full AUDIT was administered to participants at baseline and at 6- or 12-month follow-up. Sensitivity and specificity of the brief versions were calculated in comparison to the full AUDIT. Mixed effects regression models were estimated to calculate the effect sizes from the trials using the brief versions and these were compared to the originally calculated effect sizes using the full version. RESULTS: The AUDIT-C performed well at cut-off ≥ 3 for both men (sensitivity: >80%; specificity: >76%) and women (sensitivity: >84%; specificity: >88%). The AUDIT-3 performed best at cut-off ≥ 1, but with comparatively reduced validity for men (sensitivity: >77%; specificity: ≥60%) and women (sensitivity: ≥72%; specificity: >62%). Effect sizes were different by up to 52% using the AUDIT-C and up to 60% for the AUDIT-3 compared to the AUDIT. CONCLUSIONS: The AUDIT-C is recommended as a brief screening tool for community-based and clinic-based screening in Zambia among populations with high prevalence of unhealthy alcohol use. For research studies, the full AUDIT is recommended to calculate treatment effect.Item The Role of Violence Acceptance and Inequitable Gender Norms in Intimate Partner Violence Severity Among Couples in Zambia.(2021-Oct) Fine SL; Kane JC; Murray SM; Skavenski S; Munthali S; Mwenge M; Paul R; Mayeya J; Murray LK; University of Zambia School of Medicine, Lusaka, Zambia.; Zambia Ministry of Health, Lusaka, Zambia.; Centre for Infectious Disease Research in Zambia, Lusaka, Zambia.; Johns Hopkins Bloomberg School of Public Health, Baltimore, MD, USA.; CIDRZ; Centre for Infectious Disease Research in Zambia (CIDRZ)Inequitable gender norms, including the acceptance of violence in intimate relationships, have been found to be associated with the occurrence of intimate partner violence (IPV) perpetration and victimization. Despite these findings, few studies have considered whether inequitable gender norms are related to IPV severity. This study uses baseline data from a psychotherapeutic intervention targeting heterosexual couples (
