Alcohol Use, Unspecified

The study will test a computerized treatment with subjects ages 13-17 years who are seeking treatment for alcohol and/or cannabis use. Follow-up assessments will be conducted at one- and three-months following treatment.

The purpose of this study is to learn how drinking alcohol affects how people experience stress and how that is affected by the body's chemistry. Specifically, the investigators will be studying relationships of drinking and a stress hormone called cortisol. The investigators believe that results will lead us to find more effective ways to help people stop or reduce drinking when participants are drinking at harmful levels.

This is a randomized, parallel-group study designed to explore the differences between cannabis intoxication, alcohol intoxication and co-intoxication involving both alcohol and cannabis, utilizing electroencephalography (EEG) as well as more traditional intoxication measures such as breath alcohol concentration and balance metrics. If eligible for the study, participants will be randomized to complete one study session in our mobile laboratory, during which they will use either alcohol, cannabis (which will be self-administered, ad libitum) or both alcohol and cannabis.

Whole Selves is a novel print and online intervention using motivational interviewing principles and personalized feedback to address young adults' alcohol use and romantic relationship functioning. In this study, the investigators will conduct user testing interviews (online and in-person) with 10 young adults to obtain feedback on the Whole Selves intervention prototype, thereby improving its usability, relevance, and user engagement. The investigators will then conduct a single-arm feasibility study of Whole Selves with 107 young adults in order to (1) assess the intervention's acceptability and potential mechanisms and (2) assess feasibility and parameters for a future randomized trial.

Despite availability of evidence-based alcohol reduction interventions (EBI), unhealthy alcohol use remains a barrier to HIV medication adherence, viral suppression and retention in HIV care and consequently HIV treatment as prevention (TASP). Guided by complementary implementation and evaluation frameworks-the Consolidated Framework for Implementation Research (CFIR) and RE-AIM (Reach, Effectiveness, Adoption, Implementation and Maintenance), The investigators will conduct a Hybrid Type 3 effectiveness-implementation evaluating implementation trial testing whether practice facilitation, an evidence-based multifaceted implementation strategy increases reach, adoption, implementation, and maintenance of stepped care for unhealthy alcohol use in three Center for AIDS Research (CFAR) Network of Integrated Clinical Systems (CNICS) HIV clinics located in Boston, San Diego, and Chapel Hill. The investigators will secondarily test whether practice facilitation is associated with decreased unhealthy alcohol use, and improved Antiretroviral Therapy (ART) adherence and viral suppression at the patient level. In practice facilitation, a practice coach will offer tools, resources, hands-on guidance, and content expertise to assist sites in offering a stepped care model of alcohol treatment to patients with unhealthy alcohol use. Stepped care will include brief intervention, cognitive behavioral therapy, and alcohol pharmacotherapy. The practice facilitation intervention will be rolled out sequentially across sites. There will be three phases at each site: pre-implementation planning, implementation with formative evaluation, and post-implementation summative evaluation. Using mixed methods, The investigators specifically propose to meet the following specific aims: (Aim 1) Tailor the practice facilitation intervention to each site using mixed methods (pre-implementation); (Aim 2a) Determine the effects of practice facilitation on implementation of stepped care (primary) and alcohol use and HIV-related outcomes (secondary) using interrupted time series analysis with synthetic controls (summative evaluation); (Aim 2b) Determine the effect of practice facilitation on reach, adoption, and maintenance of evidence-based alcohol treatment using mixed methods (formative evaluation); and (Aim 3) Describe barriers and facilitators to implementation of alcohol-related interventions at each site to describe maintenance and inform widespread sustainable implementation.

The goal of this clinical trial (CT) is to learn more about emerging adults' and their peers. Here, we will see how co-participating with a peer in health program might impact brain and behavior change over time. Eligible youth will be invited to come in for a "Participation Day," during which they and a peer will independently complete questionnaires. With a peer, they will then complete a short health program, and undergo a brain scan (fMRI) while completing activities. Our study team will reach out to each participant individually again 3, 6, and 12 months later to learn about health behaviors over time.

80 young adult men will complete an initial survey and receive 1 of 2 types of alcohol and sexual health education and information to encourage prevention of alcohol-related problems, HIV and other sexually transmitted infections (STIs). Participants will then take pre-exposure prophylaxis (PrEP) for HIV prevention and complete a daily 5-minute, telephone-based interactive voice response (IVR) assessment of alcohol/substance use, sexual behavior and PrEP taking for 30 days. Medication will all be active PrEP. There is no placebo control in this study. Follow-up will occur after 30-days and 6-months later.
