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 overdose prevention and safety strategies (such as naloxone) 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, other safety strategies, overdose prevention and safety education, and medications for opioid use disorder. It also attends to co-occurring mental health needs and to how poverty, housing instability, and other social circumstances shape substance use and access to 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. Findings will guide a larger future study of the practice companion's effectiveness.

Harnessing Telemedicine to Improve Alcohol Use Disorder Outcomes in Primary Care Patients
The purpose of this trial is to test new programs to see if they might help people manage their health and health behaviors related to alcohol use and well-being. The program sessions focus on getting to know what's important to the participants, reviewing or setting goals, and using different skills and behaviors to better manage health. The trial will help the study team learn about ways to deliver health information in a way that is useful and interesting. This research will take place remotely (e.g., Zoom, Facetime, Phone) and participants will be randomized to the Telehealth (TeleTx) group intervention or the Enhanced Usual Care (EUC) control group. Both groups will be asked to have follow-up visits up to 12 months from the baseline visit.

Encouraging Abstinence Behavior in a Drug Epidemic: Optimizing Dynamic Incentives
Combatting the rise of the opioid epidemic is a central challenge of U.S. health care policy. A promising approach for improving welfare and decreasing medical costs of people with substance abuse disorders is offering incentive payments for healthy behaviors. This approach, broadly known as "contingency management" in the medical literature, has repeatedly shown to be effective in treating substance abuse. However, the use of incentives by treatment facilities remains extremely low. Furthermore, it is not well understood how to design optimal incentives to treat opioid abuse. This project will conduct a randomized evaluation of two types of dynamically adjusting incentive schedules for people with opioid use disorders or cocaine use disorders: "escalating" schedules where incentive amounts increase with success to increase incentive power, and "de-escalating" schedules where incentive amounts decrease with success to improve incentive targeting. Both schemes are implemented with a novel "turnkey" mobile application, making them uniquely low-cost, low-hassle, and scalable. Effects will be measured on abstinence outcomes, including longest duration of abstinence and the percentage of negative drug tests. In combination with survey data, variation from the experiment will shed light on the barriers to abstinence more broadly and inform the understanding of optimal incentive design.

Leveraging Evidence to Activate Parents
The juvenile justice (JJ) system serves over a million cases every year and represents the primary referral source for treatment of substance use and antisocial behavior in youth. However, engagement of the JJ population in treatment is alarmingly low; further, rural communities have neither access to evidence-based practices (EBPs) nor the finances and treatment infrastructure to support their delivery. However, using an innovation called task-shifting, juvenile probation/parole officers in rural communities might be able to deliver a central change mechanism for EBPs (parent activation), with the ultimate goal of improving JJ youth outcomes.

The Interactive Media and Gender-related Stressors and Strengths Study
Emerging adulthood is a key developmental period with unique challenges, including elevated risk of substance use (including risky drinking, cigarette use, and illicit drug use), eating disorder symptoms, and severe psychological distress and suicidal ideation. This critical developmental period also offers an important opportunity for interventions to prevent adverse mental health outcomes in adulthood, particularly those related to substance use and disordered eating behaviors. Research suggests several relevant potential targets for preventive interventions in this age group. Online media, especially social media (e.g., Instagram), are used by 90% of U.S. young adults, offering unprecedented access to informational and social support for young adults. Yet online media also provide new channels for harmful exposure to stigma (e.g., online harassment) and sociocultural appearance ideals for young adults. Such exposures may cause or exacerbate substance use and adverse mental health outcomes. Existing brief interventions that improve media literacy (i.e., the ability to critically analyze and interpret media) and increase resistance to harmful sociocultural appearance ideals offer promise in supporting young adults to reduce body dissatisfaction and stress and coping behaviors (like substance use and disordered eating behaviors). However, these interventions have not previously accounted for the core role of body dissatisfaction or unique dimensions of social media literacy in young adults' health. Further, existing preventive interventions in this area have primarily been developed and tested with a focus on cisgender young people. To date, there are no gender-inclusive evidence-based interventions to address both social media-based stressors (e.g., harassment, appearance ideals) and resilience factors (e.g., social support) for young adults.

Rapid Entrainment and Signal-guided Neuromodulation for Behavioral Health
RESYNC-BH is a research study evaluating a personalized, non-drug brain-and-body treatment approach for adults with ongoing behavioral health symptoms such as depression, anxiety, trauma-related symptoms, sleep problems, attention difficulties, or substance-use concerns. Rather than assigning treatment solely according to psychiatric diagnosis, treatment approaches are selected based on symptoms, physiologic measures, and clinical presentation. Treatment may include noninvasive neuromodulation, sensory stimulation, regulated breathing, and AIP-informed integrative psychotherapy. The study will evaluate whether personalized treatment approaches produce rapid and sustained improvements in behavioral health symptoms and functioning, and whether treatment response is accompanied by measurable changes in neurophysiologic, autonomic, cognitive, inflammatory, and behavioral measures. The study hypothesis is that meaningful clinical improvement is associated with measurable changes across brain, body, cognitive, and behavioral signals, and that early changes in these measures may help characterize treatment response and its durability. The long-term goal is to develop more objective and personalized methods for monitoring behavioral health treatment response.

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.

Parenting in 2 Worlds Multisite Trial
This research study will test the effectiveness of a culturally grounded parenting intervention called Parenting in 2 Worlds (P2W). This intervention is designed for American Indian / Alaska Native (AI) parents/guardians of adolescents who reside in urban areas. This will be a multi-regional effectiveness trial across four regions: Northeast (Buffalo/Niagara), Midwest (St. Paul/Minneapolis), Mountain (Denver), and Southwest (Phoenix). There are four specific aims. First, this study will test the effectiveness of Parenting in Two Worlds (P2W) as compared to an informational family health intervention, Healthy Families in 2 Worlds (HF2W), in improving parenting and family functioning. Second, this study will test if the relative effectiveness of P2W, compared to HF2W, varies by parent's/guardian's level of socioeconomic vulnerability, experiences of historical loss, or AI cultural identity. Third, this study will examine if P2W can reduce adolescent (ages 12 - 17) risky health behaviors including substance use, depressive symptoms, suicidality, and risky sexual behaviors. Fourth, this study will examine whether positive changes in parenting and family functioning that result from P2W lead to positive changes in adolescent's health behaviors.

Feasibility of Incorporating a Standardized Substance Use Measure With Linked-Brief Intervention Into Routine Psychosocial Care of Adult Childhood Cancer Survivors
The ASSIST Study is designed to explore whether a brief, evidence based substance use screening and counseling approach can be easily integrated into routine survivorship care at St. Jude Children's Research Hospital. During a regularly scheduled psychosocial visit, participants complete the World Health Organization's Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST). This short questionnaire helps identify patterns of use related to tobacco, alcohol, cannabis, prescription medications, and other substances. Survivors whose results show possible risk receive a brief, supportive counseling session during the same appointment. This session uses motivational interviewing techniques to help individuals reflect on their use and consider steps to reduce potential harm. Primary Objective: \- Assess the feasibility and acceptability of integrating a standardized substance use screening and brief intervention protocol into routine psychosocial workflows within a survivorship clinic. Secondary Objective: \- Evaluate the fidelity of delivering a brief substance use intervention to reduce substance use behaviors among survivors.

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.
