tAN for Substance Use Disorder

The study will involve a 5-day tAN treatment to attenuate alcohol withdrawal syndrome (AWS) and alter resting state functional connectivity (RSFC) between OFC and striatum in patients with alcohol use disorder (AUD). Enrolled participants will wear the tAN device on-site (at The Menninger Clinic) for the 5-day detox treatment period. Participants with AUD will be single-blinded randomized into 2 groups - a treatment group (active tAN) and a placebo group (sham tAN). Each group will consist of five separate time points - admission, screening, baseline, tAN treatment, and post tAN treatment. Clinical measures collected before, during, and after treatment will include alcohol withdrawal severity, craving, benzodiazepine usage, and assessments of depression and suicidal behaviors. Participants will undergo MRI scans before and after the treatment period to assess changes in brain connectivity and their relationship to clinical outcomes.

Peer-Delivered Behavioral Activation in a CCBHC

Low-income individuals have limited access to evidence-based interventions for mental health. Peer recovery specialists, individuals in recovery from mental health and/or substance use problems, have the potential to increase access to evidence-based interventions for individuals from low-resource communities, particularly when trained and supervised in models that are acceptable and feasible in these communities. This study will examine the effectiveness and implementation potential of a peer-delivered evidence-based intervention (Behavioral Activation) among individuals receiving services from a community-based treatment setting providing integrated physical and behavioral healthcare.

Psilocybin Assisted Psychotherapy for Treatment Resistant Depression and Co-occurring Substance Use Disorder

The goal of this clinical trial is to learn if a single dose of psilocybin (5mg Vs 10mg Vs 25mg) alongside psychotherapy is safe and can help treat treatment resistant depression (TRD) with co-occurring substance use disorder (SUD) in veterans and first responders. We seek to answer: * Whether 5mgs, 10mgs and 25mgs of psilocybin are safe in individuals with co-occurring TRD and SUD * Whether psilocybin assisted psychotherapy will reduce substance use severity and depression symptoms * What neurobiological processes are associated with the effects of psilocybin assisted psychotherapy. The researchers will compare the effects of a single dose of psilocybin (either 5mgs or 10mgs or 25mg) alongside psychotherapy on substance use severity and depression symptoms over six weeks in veterans and first responders with TRD and co-occurring SUD. In this 14-week study, participants will: * Visit the clinic for two intake sessions * Complete seven psychotherapy sessions. This will include three sessions before psilocybin administration, an 8 to 10 hour dosing session, and three sessions following psilocybin administration * Complete short, repeated daily assessments for six weeks, in total, before and after psilocybin administration * Complete two brain scans before and after psilocybin administration

Enhancing Prospective Thinking in Early Recovery

The goal of this clinical trial is to use a novel virtual reality intervention to test for efficacy in reducing alcohol use and increasing abstinence, with concomitant increases in future self-identification, future time perspective, and delay-of-reward, in early recovering stimulant use disorder (SUD) persons. The main question\[s\] this trial aims to answer are: Will the Virtual Reality (VR) intervention decrease the number of stimulant use days? Will the VR intervention produce longer abstinence periods during follow-up visits? Will the VR intervention increase alcohol abstinence rates? Will the VR intervention increase future self-identification? Will the VR intervention increase self-reported future time perspective? Will the VR intervention increase preference for delayed rewards in a laboratory delay discounting task on the study day? Will the VR intervention produce gains in the behavioral effects of future self-identification, future time perspective, and delayed rewards at the 30-day and 6-month follow-ups? Researchers will compare the experimental and control groups to see if there are differences in the results for the questions outlined above.

Smoking Cessation and Menstrual Cycle Phase

Tobacco use is a risk factor for at least 20 types of cancer and remains the leading preventable cause of cancer in Canada. Smoking cessation is an important cancer prevention strategy for the close to 2 million Canadian women who currently smoke. However, findings from controlled trials and real-world clinical settings indicate that women have greater difficulty achieving abstinence following a quit attempt than men. There is some evidence that hormonal levels and fluctuations throughout the menstrual cycle (MC) may contribute to the greater difficulty women experience when trying to quit smoking. In this study, the start of a quit attempt using nicotine replacement therapy (NRT) will be targeted to specific phases of MC. It was hypothesized that starting a quit attempt during the first half of MC (follicular phase) will result in increased quit success compared to starting during the second half of MC (luteal phase) or the usual practice of not targeting quit start date to MC phase.

A Novel Blood Test as a Biomarker in Mental Health

This longitudinal, observational study aims to assess whether the characteristics of a novel blood peripheral biomarker can serve as indicators for depression and schizophrenia in patients at the Royal Columbian Hospital Psychiatric Clinics. The study will evaluate whether changes in these biomarker characteristics can help distinguish between depressed patients who do or do not respond to treatment and between individuals experiencing a single psychotic episode and those at risk of progressing to schizophrenia. To achieve this, blood samples and standardized mental health assessments will be collected across three study visits from up to 500 participants, grouped into two study arms based on their diagnosis: Depression (DEP) or Psychosis/Schizophrenia (PSY).

Evaluation of RRFT for Co-occurring SUD and PTSD Among Teens

Psychosocial traumatic events during childhood, serve as strong and consistent predictors of substance use problems (SUP) during adolescence and adulthood.PTSD that extends from such trauma often co-occurs with SUP. Despite this well-established link, standard care for adolescents with co-occurring SUP and PTSD for the last several decades has been to treat these problems separately. This compartmentalized approach to treatment creates a burden on teens and families, raises unique challenges to clinicians in both mental health and addiction domains, and may contribute to high rates of SUP relapse among adolescents with co-occurring PTSD. To address this problem, our team recently completed a rigorous National Institute on Drug Abuse (NIDA)-funded randomized controlled trial (RCT) supporting the efficacy of an integrative, exposure-based treatment we developed, Risk Reduction through Family Therapy (RRFT), in greater long term reductions in SUP, as well as PTSD avoidance and hyperarousal symptoms, in comparison to standard treatment in a large teen sample. The proposed RCT, with an effectiveness-implementation Hybrid Type I design, substantially builds on that prior research by proposing to 1) evaluate whether RRFT's clinical effectiveness for reducing SUP and PTSD can be extended to youth in outpatient substance use treatment settings-where youth are presenting for SUP treatment and where clinicians often have less experience treating PTSD (Aim 1); 2)evaluate the cost-effectiveness of RRFT and to explore inner context variables (e.g., perceived treatment acceptability, attitudes, and satisfaction among the participating adolescents, caregivers, agency leaders, and therapists and barriers to and facilitators of implementation) that might affect RRFT implementation in diverse practice settings(Aim 2). The proposed effectiveness-implementation trial will recruit adolescents (13-18 years) with a history of psychosocial trauma presenting with SUP and PTSD symptoms for outpatient substance use disorder treatment at sites in Denver, Colorado. Participants will be randomized to RRFT or Treatment as Usual. A multi-method, multi-respondent approach will track clinical outcomes(SUP, PTSD, and putative targets of treatment, such as emotional suppression)at 3, 6, and 12 months post-baseline.

Impact of Federal and State Medications for Opioid Use Disorder (MOUD) Policy Changes During the Pandemic

"Gold-standard" medications for opioid use disorder (MOUD) treatment combines FDA-approved medications, primarily methadone and buprenorphine, with behavioral therapies to provide "whole-patient" treatment. Prior to the pandemic, methadone and buprenorphine were subject to greater federal regulations than medications for other substance use disorders, including medication for alcohol use disorder (MAUD), which created barriers to MOUD initiation and retention. These barriers were exacerbated by physical distancing and diminished clinic capacities during the COVID-19 pandemic. To prevent healthcare disruption and expand access to MOUD treatment during the public health emergency, federal and state authorities implemented several MOUD policy changes during the pandemic to reduce barriers to MOUD initiation and retention, which subsequently became permanent. This study is an evaluation of the impacts of these policies on treatment use, retention, and patient outcomes pre- and post-MOUD policy implementation.

Enhancing Addiction Treatment Through Psychoeducation

Addiction is a brain disorder characterized by a broad range of both apparent and subtle cognitive impairments in attention, memory, executive functions, and decision-making. These cognitive problems are clinically significant and may contribute to poor treatment outcomes in people with Substance Use Disorders (SUDs), such as a high risk of dropout, low treatment compliance, and shorter periods of abstinence. Studies on cognitive function in SUDs reveal that chronic use of drugs and alcohol can also negatively affect another crucial component of cognition: awareness, or metacognition. Metacognition is defined as an individual's ability to perceive and understand their cognitive functions and use this understanding to regulate them. One of the key consequences of metacognitive impairments is the lack of insight in people with SUDs, which adversely affects treatment outcomes. Substance users with poor metacognition are more reluctant to initiate or continue treatment and are more likely to deny their cognitive problems. Therefore, improving metacognition may remove or reduce motivational barriers to invest time and effort in the recovery process in general, and in the brain recovery process specifically. Despite the importance of neurocognition and metacognition in the recovery process for substance users, there is a dearth of interventions designed to target these functions.

Written Exposure Therapy for Veterans With SUD and PTSD

The proposed project will evaluate the efficacy of written exposure therapy (WET) among Veterans engaged in substance use disorder (SUD) treatment, who present with co-occurring posttraumatic stress disorder (PTSD). While SUD treatment programs traditionally do not address PTSD, effective trauma treatments have been used successfully among those with substance use comorbidities. WET is a brief trauma-focused intervention shown to effectively treat PTSD. In a recent acceptability and feasibility pilot study among Veterans with co-occurring SUD and PTSD, results showed a decrease in PTSD symptoms among participants receiving WET. The goal of the present study is to improve outcomes for Veterans who present for SUD treatment with comorbid SUD/PTSD.
