Researching Resiliency in Stressful Experiences (RISE) Program for Men Leaving Incarceration
The investigators are conducting a randomized controlled trial to assess the impact of Resiliency in Stressful Experiences (RISE) - a comprehensive trauma-based program for young men releasing from a southeastern state's prisons. The investigators are assessing whether treating trauma and providing other transitional supports - such as employment assistance - as young men return home will help to improve their community stability and enhance their psychological well-being, in turn, resulting in less likelihood that a person will become incarcerated in the future.

Adolescent Screening and Personalized Intervention Resource for Enhancement of Behavioral Health and Substance Use
Only a small fraction of youth who are beginning to experience behavioral health problems and use alcohol or illicit drugs receive needed treatment services due to the lack of accessible, effective early intervention resources. The goal of this clinical trial is to compare a personalized brief web-based early intervention, eHealth Personalized Approach for Change Efficacy (ePACE), in which youth are offered choices regarding intervention content and desired level of engagement, to a "fixed", non-tailored brief intervention, eHealth Fixed Approach for Change Efficacy (eFACE) for adolescents with mild/moderate substance use and common co-occurring problems. Both ePACE and eFACE include a multi-problem screener that guides youths through a set of key integrated behavior change and counseling modules providing a cohesive focus on these four problem domains: drug abuse, interpersonal relations, negative emotions and stress. The main questions the trial aims to answer are: * Are substance use and co-occurring problem outcomes for ePACE and eFACE are superior to those for a waitlist comparison group (WC) * Are outcomes for ePACE are superior to those for eFACE * Are the direct effects of ePACE and eFACE (i.e., the improvements in substance use and co-occurring problem outcomes) associated with improvements in areas of functioning and new skills that are hypothesized to produce change -- that is, are the improvements shown in the ePACE and eFACE groups due to the mechanisms by which change is hypothesized to occur Participants in ePACE and eFACE will complete a baseline assessment prior to engaging in the intervention to which they are assigned and will complete post-intervention assessments 3 months and 6 months later. Participants in the WC group will complete three assessments: at baseline, 3-months, and 6-months.

A Brief Intervention for Alcohol Users With Interpersonal Trauma
The current proposal aims to enhance a mobile-delivered brief intervention for young adults with heavy alcohol use and interpersonal trauma by including adaptive coping strategies for managing trauma-related distress and using peer coaches after delivery of the intervention to maintain treatment gains. Individuals will be randomized to a modified brief intervention incorporating with peer coaches, a standard brief intervention, or assessment only. Participants will be followed up at 3 and 6 months post intervention. The investigators hypothesize that the trauma-informed and peer-supported brief intervention (TIPS-BI) will show low levels of dropout, will be perceived positively by participants, and will result in greater reductions in alcohol use compared to a standard brief intervention and assessment only.

Alliances to Disseminate Addiction Prevention and Treatment (ADAPT)
Youth involved in the juvenile justice system (YJJ) bear a disproportionate burden of the addiction crisis. YJJ substance use (SU) is extremely prevalent, with a third of YJJ meeting criteria for a substance use disorder (SUD). The investigators seek to address the national addiction crisis at its epicenter. Despite their high need for SUD services, and the proliferation of evidence-based interventions to reduce SU, YJJ are rarely connected to needed, high-quality SU care. A care cascade model highlights gaps in YJJ achieving the full continuum of SUD care (i.e., SUD risk identification, treatment referral, treatment initiation, and treatment engagement). YJJ on community supervision/probation face a unique problem accessing SUD services; while the courts or probation may identify YJJ need for SUD care, YJJ must receive care through healthcare agencies in the community. The primary goal of the project, Alliances to Disseminate Addiction Prevention and Treatment (ADAPT) is to address this and other gaps along the care cascade for YJJ. The investigators will accomplish this goal by creating alliances between the juvenile justice system (JJ) agencies and community mental health centers (CMHCs) in eight Indiana counties. ADAPT takes a two-pronged approach. First, the investigators will employ a Learning Health System (LHS) to develop collaborative alliances between JJ agencies and CMHCs, organizations that traditionally operate independently. Second, the investigators will present local Cascade data during continuous quality improvement cycles within the LHS alliances. By offering agency representatives an opportunity to view and discuss, for example, the local rate at which YJJ with SUD risk are initiating CMHC SU services, the investigators will facilitate development of tailored, local solutions to improve the Cascade for each county's YJJ. To maximize long-term sustainability of ADAPT's JJ-CMHC alliances, the investigators will conduct this research in collaboration with leaders from an existing statewide initiative, the Juvenile Detention Alternatives Initiative (JDAI). JDAI is a juvenile justice reform effort that utilizes data-driven decision-making and is implemented in almost 300 counties across the US. If this project is successful, the JDAI infrastructure and support for this research will inform sustainment and expansion across Indiana and the nation. The investigators hypothesize that ADAPT - novel LHS alliances using Cascade data to implement localized solutions to YJJ receiving evidence-based addictions care - will positively impact SU and recidivism outcomes over time. The investigators seek to complete the following specific aims: AIM 1: Implement LHS alliances between JJ agencies and CMHCs. The investigators will establish LHS alliances: novel, collaborative partnerships between JJ agencies and CMHCs. AIM 2: Generate and track local solutions to address gaps in the Cascade for YJJ in rural Indiana counties. Quantifying local Cascade data will enable JJ agencies and CMHCs to suggest and implement tailored, evidenced-based interventions, which will be tracked through LHS quality improvement cycles. AIM 3: Assess implementation outcomes and processes. We will assess implementation outcomes, such as system alliance, among JJ and CHMC personnel using mixed methods. AIM 4: Assess the impact of ADAPT. Conduct a stepped wedge cluster randomized controlled trial to assess the impact of LHS alliances on the Cascade for YJJ. We will analyze administrative data linked across JJ and health systems to assess the long-term, community-wide effects of ADAPT on public health and safety outcomes (e.g., lower rates of SU-related outcomes and criminal recidivism).

Clinician Practice Companion to Address Youth Substance Use
Substance use, including the use of opioids, cannabis, and other drugs, is common among adolescents and young adults, and overdose has become a leading cause of death among youth in Canada and the United States. Many young people who use substances also experience co-occurring mental health concerns. Evidence-based approaches to youth substance use care exist, including harm reduction, overdose prevention (such as naloxone and take-home drug testing strips), and medications for addiction treatment. These approaches remain adult-oriented, however, unevenly implemented in youth-serving settings, and insufficiently centered on the needs and goals of youth and their families. This study develops and pilot tests a written "practice companion" that helps clinicians and other trusted adults provide developmentally appropriate substance use care to youth ages 14 to 24 in hospital and community settings. The practice companion offers practical, easy-to-use guidance organized by substance and by pattern of use. It addresses cannabis and other substances that youth commonly use and that clinicians frequently seek support with, alongside a strong focus on overdose prevention through its core elements: naloxone, take-home drug testing strips, harm reduction education, and medications for opioid use disorder. It also attends to co-occurring mental health needs and to how gender, sexuality, housing instability, and other social and structural contexts shape substance use and care. The research team will first interview youth who use substances, their families and caregivers, and clinicians to learn how each element of care should be adapted for young people. The team will then produce the practice companion and pilot test it with 60 youth across three sites, in British Columbia, Québec, and Massachusetts. After receiving care guided by the practice companion, youth will complete an interview about whether the care was relevant, useful, appropriate, and acceptable. Families and clinicians will also be interviewed to assess how feasible, sustainable, and faithful to its design the practice companion is in practice. Throughout the study, the team will work closely with youth and families who have lived experience through a community-based participatory research approach that includes Community Advisory Boards. The work centers equity for Black, Indigenous, and other racialized youth, Two-Spirit and LGBTQ+ youth, and youth experiencing housing instability. Findings will guide a larger future study of the practice companion's effectiveness.

Leveraging Social Networks to Increase COVID-19 Testing Uptake
This two-year project will adapt and conduct a trial examining the ability of two recruitment strategies, chain-referral and credible messenger, to reach those who use opioids and other substances in order to increase their uptake of onsite point of care COVID-19 testing that will be delivered in two community based organizations (CBOs): Alliance for Positive Change and Argus Health Inc. In Phase 1, Adapt two implementation strategies to support COVID-19 testing uptake and sustainability, adapting elements of existing efficacious social network-based interventions via a CBPR approach. In Phase 2, we will examine and compare the efficacy of two sets of implementation strategies on (i) reach, (ii) testing uptake, (iii) service delivery (i.e. quarantine, medical care, contact tracing) and (iv) sustainability for individuals who use opioids and other drugs. In Phase 3, Elucidate and compare the system/organizational-, staff-, and individual-level factors that influence implementation (i.e. fidelity, acceptability, feasibility, sustainability) of the strategies to develop a plan for dissemination and scale-up in other CBOs who serve opioid and other substance using individuals in NYC.

Harm Reduction in HIV Primary Care for PLWH Who Use Drugs
People living with HIV (PLWH) who use drugs experience significant health disparities including lower rates of retention in HIV care and higher rates of unsuppressed viral load, resulting in secondary infections and increased mortality. The proposed study will used mixed methods to explore (a) the relationship between healthcare providers' attitudes towards working with PLWH who use drugs and providers' acceptance and practice of structural and relational harm reduction; (b) the degree to which relational harm reduction moderates the effect of intersectional stigma experienced in healthcare settings on patients' perceptions of their relationship with providers; (c) the degree to which structural HR moderates the relationship between the patient-provider relationship and clinical outcomes, and (d) whether patient-perceived HR approaches to care are directly associated with HIV clinical outcomes. The study will also use these findings to inform the development and pre-testing of an intervention to operationalize harm reduction in HIV clinical settings, using stakeholder-engaged and human-centered design approaches, presenting a novel path to reducing HIV health inequities for PLWH who use drugs.
