Brief Intervention Addressing Stigma Among Parents of Children With Mental Health Problems

The goal of this study is to test the efficacy of brief video interventions parental internalized stigma and stigma-related outcomes (e.g., treatment intentions, caregiver burden, secrecy) among parents (ages 25-50) of children ages 6-18 with depression, ADHD, or substance use problems. Timely identification and treatment of mental health problems in youth is a public health priority. However, many youth do not receive treatment, and stigma has been identified as the primary barrier to help-seeking. Parents experience stigma related to their children having mental health problems, which has been associated with reduced help-seeking and increased parental distress. Prior experiments have found brief video-based interventions (BVIs), 1-2 minute videos similar to those viewed by youth on social media platforms, based on the principle of "social contact" with individuals affected by a stigmatized condition, effective in reducing mental health stigma and increasing help-seeking. In this 4-arm RCT, the investigators will recruit parents aged 25-50 using an online crowdsourcing platform, to test the efficacy of BVIs featuring a personal parent narrative of their experience with their child's a) depression, b) ADHD, or c) substance use, or d) a control condition that provides general written psychoeducational information without social contact.

Hybrid Dialectical Behavior Therapy for Veterans to Further Reduce Emotion Regulation Problems and Trauma Symptoms

Around 10% of post-active veterans experience post-traumatic stress disorder (PTSD) many years post-mission. PTSD in veterans is frequently associated with challenges in emotion regulation, aggression, suicidality, and financial and psychosocial stress. In 2018, a 12-week clinical treatment programme, the Veterans Intensive Treatment Unit (VIBU), was developed for veterans experiencing these psychiatric symptoms, for whom conventional treatments had proven ineffective. The VIBU provides patients with trauma-focused and dialectical behaviour therapy (DBT). A recent study revealed that the VIBU was effective in reducing psychiatric symptoms. However, a recurrence of symptoms was observed in patients a few months after discharge. Consequently, an aftercare programme consisting of hybrid DBT is offered to consolidate and repeat the DBT skills and apply them in daily life.

Testing a Mobile Health Application to Improve HIV Prevention and Substance Use Treatment Among Women Involved in the Carceral System

Women involved in the carceral system (WICS) are at higher risk for both HIV and substance use than the general public. WICS are also more likely to engage in behaviors both before and after release that put them at risk for HIV and for overdose, due to opioid use. Despite these risk factors, WICS are less likely to be aware of, use, or adhere to pre-exposure prophylaxis (PrEP) and have less access to medications for opioid use disorder (MOUD). The primary goal of the proposed research is to pilot test a systematically developed PrEP and MOUD uptake intervention for WICS using contextually relevant messages developed through novel formative research methods and embedded in a web-based application in a rigorous research design. The investigators will then test this approach (called PA-LINKS) in a pilot randomized trial with women who have recently been incarcerated in Philadelphia in partnership with Philadelphia FIGHT, a federally qualified health center, for promise of efficacy, and to assess feasibility and acceptability.

Comparison of the Italian and U.S. Forensic Models for Dual-diagnosis Offenders: a 3-year Longitudinal Study

This study aims to compare the Italian and U.S. forensic models in the treatment of offenders with dual diagnosis through a three-year longitudinal design. In Italy, the closure of Judicial Psychiatric Hospitals following Law 81/2014 led to the establishment of a community-based forensic system centered on REMS (Residences for the Execution of Security Measures), integrated within the National Health Service. This model seeks to limit institutionalization and promote rehabilitative pathways in community settings. However, it continues to face challenges related to limited bed availability, waiting lists, and the complex management of social dangerousness. In contrast, the U.S. system, particularly in California, is characterized by high-security forensic psychiatric hospitals with large capacities, but also presents issues such as prolonged hospitalizations, an aging patient population, and a high prevalence of substance use disorders. Dual diagnosis, defined as the co-occurrence of psychiatric disorders and substance use disorders, is highly prevalent in forensic populations and is associated with increased clinical complexity, higher risk of recidivism, and poorer treatment outcomes. Neurobiological and psychological mechanisms underlying addiction-including dysfunctions in the dopaminergic reward system, craving processes, and impairments in executive functioning-contribute to reduced behavioral control and increased impulsivity. Theoretical models such as the self-medication hypothesis and multifactorial frameworks suggest that substance use may both exacerbate psychiatric symptoms and represent an attempt to regulate them. Given these complexities, integrated treatment approaches that combine psychiatric care and addiction interventions are essential, particularly in forensic settings. The present study includes offenders with mental illness in forensic care systems in Italy and California, encompassing both custodial and non-custodial settings. Participants will be followed over a three-year period, with assessments conducted at 12, 24, and 36 months. The methodology involves the use of standardized instruments to evaluate psychopathological severity, global functioning, risk of violent recidivism, protective factors, treatment adherence, impulsivity, and substance use. Data on clinical outcomes, antisocial behaviors, and discharge conditions will also be collected. The primary objectives of the study are to describe and compare the clinical, demographic, and criminological profiles of forensic populations with dual diagnosis; to examine treatment pathways and outcomes; to identify indicators of treatment effectiveness; and to evaluate both risk and protective prognostic factors, as well as their predictive value for recidivism and clinical trajectories. The expected impact of the study lies in improving the understanding of differences between community-based and hospital-based forensic models, with the goal of identifying integrated strategies capable of enhancing rehabilitation, reducing recidivism, and improving long-term outcomes. Findings may contribute to the development of more effective and individualized treatment approaches, as well as inform health and judicial policies aimed at better integrating clinical care and risk management in dual diagnosis forensic populations.

Micropractices for Unhoused LGBTQ Youth

In the present study, the investigators will conduct a pilot randomized controlled trial to evaluate the feasibility, acceptability, and preliminary efficacy of brief, co-designed mindfulness and identity-affirming micropractices for LGBTQ youth and young adults experiencing housing instability. Participants (n = 200, accounting for anticipated attrition) will be randomly assigned to one of two conditions: (1) a mindfulness and identity-based micropractice condition or (2) a structurally equivalent neutral control condition. The intervention content will be developed using a participatory co-design process with members of the target population and standardized prior to trial implementation. The mindfulness and identity condition integrates brief practices targeting present-moment awareness and identity affirmation, whereas the control condition accounts for time and attention without including these components. Assessments will be conducted at baseline, post-intervention, and three-month follow-up. Primary outcomes include feasibility and acceptability, assessed using standardized implementation outcome measures and indicators of intervention adherence. Secondary outcomes include changes in mental health symptoms, psychological and emotional well-being, and substance use. The investigators will evaluate whether the mindfulness and identity-based condition demonstrates greater improvements in outcomes compared to the control condition and will estimate effect sizes to inform the design of future fully powered trials. The intervention will be delivered via a mobile-accessible platform.

SER Familia: A Family-Based Intervention Addressing Syndemic Conditions Among Latino Immigrant Families

This study aims to prevent syndemic health conditions by decreasing acculturative stress and promoting resilience via SER Familia (Salud, Estrés y Resilencia en Familias/ Health, Stress, and Resilience in Families), a family-based intervention. SER Familia is a six-session intervention co-developed and delivered by community health workers (CHWs) that uses strategies to reduce acculturative stress, promote resilience, improve parent-child and family level health, while simultaneously helping families maintain strong social networks and better navigate community resources to address social determinants of health (SDOH). More specifically, investigators aim to: 1) Examine the efficacy of SER Familia to prevent or reduce the syndemic comprised of substance abuse, IPV, HIV risk, depression, and anxiety among Parents and Youth; and 2) Identify how individual, family, and community mechanisms of change related to acculturative stress and resilience mediates the effect of SER Familia.

Data2Action Oregon Project: Supporting Data-driven Decision-Making for Substance Use Services, Policy, and Overdose Prevention

Oregon's decision makers (e.g., community service providers, public health, justice, advocacy groups, payers) are calling for comprehensive, current, and trusted data to inform how they allocate resources to improve substance use services and mitigate the growing opioid and methamphetamine epidemics in their state. Consistent with the HEAL Data2Action call for Innovation projects that drive action with data in real-world settings, this study will refine and test the impact of a novel implementation strategy to engage cross- sector decision makers and make data that they identify as relevant to their decisions available to them in easy- to-use products. The proposed study aims to not only address critical knowledge gaps regarding how and when data can inform impactful, transparent decision-making, but to provide decision makers with the data that they need to achieve community-wide substance use prevention and treatment goals, including the increased delivery of high-quality, evidence-informed, services and the prevention of overdoses.

Feasibility of Long-term, High-dose Stimulant for Methamphetamine Use Disorder

Methamphetamine use disorder (MUD) is becoming an increasing public health concern in Canada. While the evidence on the efficacy and safety of prescription psychostimulants for the treatment of MUD is promising, the knowledge on the maintenance therapy using stimulant agonist therapy is scarce and needs further investigation, especially in terms of long-term retention in treatment. The goal of this clinical trial is to evaluate the feasibility of a long-term (25 weeks) administration of high-dose stimulant agonist therapy, using Lisdexamfetamine (LDX-01) on top of treatment-as-usual (TAU), in a population of people with moderate to severe MUD, as measured by study retention, treatment retention, treatment adherence and satisfaction compared against a placebo group. Participants will be placed randomly into one of two groups: 1. TAU and high-dose LDX-01 2. TAU and placebo

Treatment Outcomes Under a Standardized Treatment Protocol in Patients Suffered Substance Abuse Related Voiding Dysfunction

With the increase of substance abuse over the world, substance abuse e.g. ketamine and methamphetamine related voiding dysfunction is becoming an important medical problem. However, while the clinical manifestation of the condition is becoming better defined, the underlying pathophysiology is still poorly understood. Moreover, majority of the current treatment is just based on the experience on some small case series and there is no treatment data for larger patient sample or standard recommended treatment in the literature. In order to improve the management of this condition, investigators have formulated a treatment protocol based on the current literatures on the management of voiding dysfunction and also a similar condition, interstitial cystitis / painful-bladder syndrome (IC/PBS). The protocol basically consists of the following modalities: * Basic information and education on the condition, principle of treatment and psychosocial support. * First line treatment will include a course of oral anti-inflammatory drugs (for the control of the inflammation process and pain) and anticholinergic agents (for the irritative urinary symptoms). * If these simple oral medication are found to be not effective, then further treatment will include other oral medications, such as amitriptyline and gabapentin, and some drugs that directly applied into the bladder cavity (hyaluronate) or bladder muscle (botulinum toxin). * For those patients with intractable symptoms and failed all the above treatments, surgical treatment (hydrodistension, augmentation cystoplasty) will be discussed. The purpose of this research is to assess the effectiveness of the above treatment protocol in the management of substance induced voiding dysfunction and also assess any possible adverse events related to the usage of the drugs.

Functional Connectivity Alterations in Suicidal Patients Among Opioid Users

Suicide is the 10th leading cause of death for Americans of all ages and more people in the United States now die from suicide than die from car accidents. Although death by firearm remains the most common cause of suicide in the United States, an intentional overdose of substance usage such as prescription opioids accounts for over 5,000 suicides per year. In 2017, more than 70,000 drug overdose deaths occurred, making it the leading cause of injury-related death, and well over half (67.8%) involved opioids. The dramatic increase in opioid overdose raises concerns about their contribution to suicidal outcomes (e.g., suicidal behavior, ideation, and attempts). Abuse of prescription opioids is characterized by the persistence of opioid use despite negative consequences. The neurobiology of opioid abuse involves the mesolimbic dopamine systems as the main neural substrate for opioid reward, and altered dopamine release in this system plays a role in opioid abuse. Moreover, the cortico-striatal system, especially the orbitofrontal cortex (OFC), has been associated with the abuse of many substances, including opioids and alcohol. Structural brain alterations in frontal areas, particularly the OFC, may cause executive control dysfunctions of mood which are highly associated with suicidal ideation. Recent preclinical work has shown that higher input from the OFC to the dorsal striatum (dSTR) is associated with compulsive reward-seeking behavior despite negative effects (e.g., punishment). In this study, the investigators propose that OFC/dSTR connectivity may be one neural differentiator that distinguishes between those who become compulsive users after initial opioid use and those that do not. Moreover, suicidal patients among those who become compulsive users may have higher OFC/dSTR connectivity compared to non-suicidal patients.

Testing Strategies to Improve Substance Misuse Prevention Research Use in State Policy Contexts

If science is to inform effective substance misuse prevention policy and ultimately improve public health, the field needs an effective strategy for directly supporting policymakers' use of research evidence, yet our field lacks an evidence-based model designed for this purpose. Accordingly, a state-level randomized controlled trial (N = 30 states) of a formal, theory-based approach for appropriately supporting policymakers' use of scientific evidence--known as the Research-to-Policy Collaboration (RPC) Model is proposed. This work has the potential to reduce population-level substance misuse by improving the use of scientific information in policymaking, thus increasing the availability of evidence-based prevention programs and policies.
