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.

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.

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.

The Development and Evaluation of a Culturally Grounded ENDS Intervention for Rural Hawaiian Youth

The purpose of this research proposal is to develop and evaluate a culturally grounded, ENDS prevention intervention for rural Hawaiian youth. This will be accomplished through two specific aims. AIM 1 (Years 1-3) are focused on pre-intervention and intervention development. In Year 1, youth focus groups will be conducted to assess the environmental demands related to ENDS use in rural Hawai'i. In Year 2, specific ENDS-related problem situations (i.e., situations that increase risk for ENDS use) will be extracted from the Year 1 focus groups and prioritized through survey methods with 200-250 predominately Native Hawaiian youth across 16 different middle/intermediate schools on Hawai'i Island. In Year 3, five situations found to be the most frequently experienced and/or difficult to manage by youth surveyed in Year 2 will serve as the foundation for the development of narrative scripts. Three of these scripts will be cast and filmed on location on Hawai'i Island by a professional film director, and will be edited into three short films, 6-8 video clips, and 6-8 professional photos or production stills. Similar to the investigators' prior drug prevention research in rural Hawai'i, classroom-based lessons will be created to support the short films. Additional lessons and videos from an evidence-based, culturally grounded substance abuse prevention curriculum for Hawaiian youth (Ho'ouna Pono) will be used to create a modular classroom curriculum. The video clips and professional photography/production stills will be embedded with prevention messaging, and will be used for a social and print media campaign to reinforce the classroom curriculum. AIM 2 (Years 4-5) is to evaluate the ENDS prevention intervention (classroom curriculum plus social/print media campaign) across all middle/intermediate public or public-charter schools (N = 16) and up to 11 different cultural immersion charter schools on Hawai'i Island using a dynamic wait-listed control group design.
