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.

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.

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.

Family Spirit Strengths

This project addresses the disproportionate morbidity and mortality associated with mental and behavioral health problems in American Indian and Alaska Native communities. Access to culturally competent and effective behavioral health services is limited in many of these communities. The investigators aim to address this gap by testing the effectiveness of a trans-diagnostic secondary prevention program, Family Spirit Strengths (FSS) that can be embedded within home visiting services. The FSS program is a skills-based program that incorporates elements of evidence-based practice, the Common Elements Treatment Approach (CETA), and materials informed and developed based on an Indigenous advisory group. The FSS program aims to help participants build self-efficacy and coping skills, as well as build stronger connections to others, the participants' community, and cultural resources. The investigators will use a randomized controlled trial, whereby half of the participants will receive FSS and the other half will receive an evidence-based nutrition education program. The investigators' study is grounded in participatory processes and led by a team of Indigenous and allied researchers.
