Faculty Publications

Interventions to teach protective behaviors may be differentially effective within an adolescent population. Identifying the characteristics of youth who are less likely to respond to an intervention can guide program modifications to improve its effectiveness. Using comprehensive longitudinal data on adolescent risk behaviors, perceptions, sensation-seeking, peer and family influence, and neighborhood risk factors from 2564 grade 10–12 students in The Bahamas, this study employs machine learning approaches (support vector machines, logistic regression, decision tree, and random forest) to identify important predictors of non-responsiveness for precision prevention. We used 80% of the data to train the models and the rest for …

Comparing Standard Versus Enhanced Implementation Of An Evidence-Based Hiv Prevention Program Among Bahamian Sixth Grade Students: Findings From Nationwide Implementation Trials, Bo Wang, Lynette Deveaux, Carly Herbert, Xiaoming Li Ph.D., Lesley Cottrell, Richard Adderley, Maxwell Poitier, Arvis Mortimer, Glenda Rolle, Sharon Marshall, Nikkiah Forbes, Bonita Stanton

Background Effective implementation strategies are needed to address the challenges encountered by teachers in implementation of evidence-based HV prevention programs in schools. The current study: 1) compares implementation fidelity of Focus on Youth in the Caribbean (FOYC) plus Caribbean Informed Parents and Children Together (CImPACT)intervention using enhanced implementation strategies (including biweekly monitoring/feedback and site-based mentoring) to those using more traditional approach (teacher training only); and 2) evaluates the impact of school coordinators’ and mentors’ performance on teachers’ implementation fidelity and student outcomes.

Methods

Data from an enhanced implementation trial in 2019–2020, involving 24 government primary schools, 79 teachers, and …

The Effectiveness Of Two Implementation Strategies For Improving Teachers' Delivery Of An Evidenced-Based Hiv Prevention Program, Bo Wang, Lynette Deveaux, Lesley Cottrell, Xiaoming Li, Richard Adderley, Barbara Dorsett, Regina Firpo-Triplett, Veronica Koci, Sharon Marshall, Nikkiah Forbes, Bonita Stanton

Faculty Publications

Background Efective implementation strategies are needed to enhance the success of evidence-based prevention programs. The current study evaluates the efects of two implementation strategies on teachers’ implementation of an evidenced-based HIV intervention.

Methods Using our 7-item pre-implementation school screening tool, we identifed teachers who were at-risk for not implementing the Focus on Youth HIV-risk reduction intervention curriculum which targets grade six through grade 8 students. After completing a two-day curriculum workshop, 81 low- and moderate-performing teachers were randomly assigned to one of four experimental conditions and were asked to teach the two-month intervention curriculum. This optimization trial examines the impact …

Pre-Exposure Prophylaxis (Prep) Uptake Among Black Men Who Have Sex With Men (Bmsm) In The Southern U.S, Oluwafemi Adeagbo, Sayward Elizabeth Harrison, Shan Qiao Ph.D., Xiaoming Li Ph.D.

Faculty Publications

Black men who have sex with men (BMSM) living in the United States (U.S.) South are disproportionately affected by HIV and experience significant disparities in HIV incidence, access to HIV care, and prevention across ages and socio-economic statuses. The aim of this commentary is to critically review current literature on the state of PrEP use among BMSM in the U.S. South, including identifying barriers and facilitators to PrEP use in order to inform intervention development. Extant literature shows that despite the documented benefits of PrEP as an effective HIV-prevention method, its uptake among BMSM is limited across the U.S. South. …

Psychological Fears Among Low-Paid Female Sex Workers In Southwest China And Their Implications For Hiv Prevention, Shan Qiao Ph.D., Xiaoming Li Ph.D., Chen Zhang, Yuejiao Zhou, Zhiyong Shen, Zhenzhu Tang, Bonita Stanton

Faculty Publications

Commercial sex plays a critical role in rapidly increasing heterosexual transmission of HIV in China. Low-paid female sex workers (FSWs) are especially vulnerable to HIV/AIDS. Because of the illegality and stigma associated with sex work, FSWs may constantly live with fears in their daily life. Based on cross-sectional study of 794 low-paid FSWs in China we described their psychological fears related to commercial sex and examined the associations between fears and HIV-related behaviors. Fear of HIV infection was significantly associated with consistent use of condoms with clients. However, fear of breaching sex worker identity significantly prevented the FSWs from consistently …
