Implementing A Secure Firearm Storage Program in Illinois Health Centers in Partnership With AllianceChicago and the Illinois Primary Health Care Association (COMMUNITY ASPIRE)

This randomized controlled trial will take place in up to 15 community health centers across the state of Illinois. Researchers will be studying S.A.F.E. Firearm, a program that aims to increase secure storage of firearms in homes with children. Specifically, S.A.F.E. Firearm includes a brief conversation between pediatric clinicians and parents/guardians about secure firearm storage and an offer of a free cable firearm lock within the well-child visit. Researchers will also study a package of strategies to help pediatric clinics incorporate this new practice. The strategies include training for clinic personnel and facilitation, or tailored problem-solving support. The questions the study aims to answer are: * How effective is the package of strategies at helping pediatric clinics implement this new practice? * How effective is the S.A.F.E. Firearm program at changing parents', caregivers' and guardians' (hereafter, "parents") firearm storage behavior? Some parents will be invited to complete a brief survey after their visit about their experiences receiving S.A.F.E. Firearm. Some community health center personnel will also be invited to complete an interview about their experiences with S.A.F.E. Firearm and the package of strategies.

Inhaled DMT for Major Depressive Disorder

This Phase 2b, randomized, double-blind, active-controlled clinical trial will evaluate the efficacy and safety of inhaled N,N-dimethyltryptamine (DMT) in adults with Major Depressive Disorder (MDD). The study will test whether inhaled DMT can rapidly reduce depressive symptoms and suicide risk compared with a low-dose active comparator. A total of 140 participants will be randomized 1:1 to receive either 15 mg followed 1 hour later by 60 mg of inhaled DMT, or 1 mg followed 1 hour later by 4 mg of inhaled DMT. Participants who do not achieve remission at Day 7 will enter an open-label extension and receive a high-dose DMT session on Day 14 (±3 days). All participants will be followed for up to 12 months to evaluate the durability of response, safety, functioning, and quality of life.

Investigation of the Antidepressant Effects of (2R,6R)-HNK, an Enhancer of Synaptic Glutamate Release, in Treatment-Resistant Depression

Background: Major depressive disorder (MDD) is a serious mental illness that can put people at risk of self-harm and death. Many drugs are used to treat MDD, but it can take a long time for them to be effective. Researchers want to know if a faster-acting drug, (2R,6R)-hydroxynorketamine (HNK), can better treat the symptoms of MDD. Objective: To test a study drug (HNK) in people with MDD. Eligibility: People aged 18 to 70 years with MDD. They must have had a screening assessment under protocol 01-M-0254. Design: Participants will be tapered off their current MDD drugs over 2 to 5 weeks. They will stay off of the drugs for up to 2 weeks prior to starting the study medication and procedures. They will have a physical exam with blood tests. They will have tests of their heart function, mood, and thinking. They will answer questions about their symptoms. They may choose to have imaging scans and scans of their brain activity. HNK is given through a tube attached to a needle inserted into a vein. Participants will receive infusions on this schedule: They will receive 4 infusions over 2 weeks. They will stay in the clinical center overnight after each infusion or for the duration of the study. They will receive no drugs for 2 to 3 weeks. They will have 4 more infusions over 2 weeks, with overnight stays after each or for the duration of the study. One set of 4 infusions will be the HNK. The other set of 4 infusions will be a placebo. A placebo looks just like the real drug but contains no medicine. Participants will not know when they are getting the HNK or placebo. ...

Public Messaging to Increase Treatment Seeking for Veterans at Risk for Suicide

The risk for suicide increases by nearly 50% in the first year that service members transition from the military to civilian life underscoring the need for effective strategies to facilitate help seeking among Veterans vulnerable to self-directed violence. Yet despite a great need for treatment, more than half of returning Veterans at risk for suicide do not initiate mental health services. VA has embarked on the regular use of communication campaigns as part of a public health approach designed to reach the larger Veteran population with messages promoting help seeking. However, what types of messages effectively change beliefs and behaviors for at-risk Veterans resistant to seek treatment is unclear. The main objective of this study is to develop and test the use of public messaging to increase treatment seeking among Veterans at risk for suicide and resistant to seek mental health care following separation from military service. This represents the first study to systematically develop public messaging strategies for populations at risk for suicide.

Preventing Suicidal Behavior With Diverse High-Risk Youth in Acute Care Settings

The study will compare the effectiveness of two relatively brief and scalable evidence-based interventions: the Stanley Brown Safety Planning Intervention and Follow-up Contacts (SPI+), a suicide-specific intervention that helps people prevent suicidal crises from escalating, and Interpersonal Psychotherapy for Adolescents Ultra Short Crisis Intervention (IPT-A SCI), a psychotherapeutic crisis intervention treatment for suicidal adolescents that teaches youth skills to prevent suicidal crises and addresses interpersonal problems that lead to suicidal crises. The results will inform the future standard of care for youth at risk for suicide presenting in the ED setting. This project focuses on suicidal youth ages 12-24 in five ethnically and racially diverse urban areas: Philadelphia, Pennsylvania; Baltimore, Maryland; Chapel Hill, North Carolina; St. Petersburg, Florida; and Northern Manhattan/lower Bronx/eastern Queens communities in New York City, New York.

Sleep and Circadian Interventions for College Students at High Risk of Suicide

The purpose of this study is to examine the extent to which delivering sleep and circadian focused interventions in addition to evidenced based psychiatric care for depression and suicide risk may contribute to decreasing suicide risk among high risk young adults. Investigators will evaluate three interventions targeting sleep in acutely suicidal college students enrolled in intensive outpatient treatment. Participants will be randomly assigned to one of three intervention groups: 1. Triple Chronotherapy (TCT)+ Transdiagnostic Sleep and Circadian Intervention (TSC) 2. Transdiagnostic Sleep and Circadian Intervention (TSC) 3. Sleep Feedback (SF) Participants will be followed for 6 months with primary outcome domains of suicidal thoughts and behaviors and depression evaluated by blinded clinicians at short (Days 1-4 of intervention), medium (2 months) and long (6 month) term intervals.

Caring Connections Youth Suicide Detection and Intervention Study

The goal of this pilot randomized control trial (RCT) is to test the feasibility of Caring Connections, a Culturally Adapted Linking Individuals Needing Care (CA-LINC) suicide prevention care coordination intervention for high-risk suicidal youth. This consumer-, community-, and theory-driven care coordination intervention is designed to reduce suicide ideation and behavior (SIB) by improving service engagement. Connections is a 90-day intervention that integrates engagement and follow-up strategies to assess/monitor suicide risk, facilitate service use referrals/linkages, develop/refine safety plans, and create villages of care. The intervention incorporates cultural promotive factors, empowerment, and motivational strategies aimed at supporting youth, enhancing strengths, promoting hope, improving family relationships, and reinforcing caring messages. Primary research questions include: Is Caring Connections feasible to use for suicidal high-risk youth? Does Caring Connections have the potential to reduce suicide ideation and behaviors among high-risk suicidal youth? For the pilot RCT, 80 youth participants ages 13-19 who meet the inclusion criteria will be randomly assigned to one of two conditions: Caring Connections (n=40) or Treatment as Usual (n=40). Additionally, investigators will enroll 80 caregivers of youth meeting inclusion criteria and 20 Mental Healthcare, Healthcare Providers, Community Stakeholders, and/or Care Coordinators with experience working with suicidal youth. Researchers will compare those receiving Caring Connections with treatment as usual to see if suicidal ideation and behaviors, and engagement.

Brief Admission by Self-referral for Individuals With Self-harm: Effects on Compulsory Care

Brief Admission by self-referral (BA) is a standardized treatment model, providing patient-controlled and person-centered care. It was developed to reduce self-harm and compulsory care by promoting autonomy. Randomized clinical trials have not yielded significant between group differences with respect to inpatient care, including compulsory care. The major difficulty in evaluating BA is preventing the control group from cross-contamination, as in the implementation process of BA, all physicians, all inpatient and outpatient staff as well as managers need to be informed and undergo basic education regarding the intervention. As BA addresses a prevalent and frustrating issue in psychiatric health care, there is considerable risk that the approach leaks to the control group, reducing the possibility to detect between-group differences. In the current study this will be addressed through a register-based approach, comparing similar clinics, implementing BA at different timepoints over time. Individuals with traits of borderline personality disorder will be included and comparisons will be made with respect to compulsory care, voluntary inpatient care and mortality.

Peer Delivered Youth Suicide Prevention in Nepal

South Asia has the highest suicide rate in the world with important risk profile differences from high-income settings. Investigators will conduct formative research to co-design a package of brief interventions and implementation strategies to prevent youth-suicide and then test the package in a pilot feasibility hybrid type 2 cluster randomized controlled trial in Nepal. Potential health impacts may be substantial as results can be applied not only in similar South Asian primary healthcare contexts, but also in low-resource settings in the US and abroad, where the suicide burden remains high. Using experience-based co-design and equity-focused implementation frameworks, this study will assess the feasibility and acceptability of a Youth-focused, Peer-delivered, Family-engaged Suicide Prevention Package (YPF-SuPP) integrated within existing mhGAP services in Nepal's decentralized primary healthcare system. This pilot trial will generate preliminary data to inform the design of a future fully powered effectiveness trial and potential scale-up of youth suicide prevention strategies.

mHealth-supported Skills Training for Alcohol-Related Suicidality

Suicide is a high priority public health problem and an increasingly prevalent alcohol-related consequence. One-third of people who die by suicide consume alcohol at hazardous rates in the year preceding death. Most people in an acute suicide crisis who present for treatment are admitted to acute psychiatric hospitalization. Yet, the 30-day period following discharge from hospitalization is by far the riskiest period for another suicide crisis. The specific aim for this project is to use a successive cohort design to iteratively develop an intervention called mHealth-supported Skills Training for Alcohol-Related Suicidality (mSTARS). The study team will adapt and iteratively refine a cognitive-behavioral skills training intervention in emotion regulation to be administered in an acute care setting and paired with a post-discharge mHealth app that encourages application of these skills to real life. Two cohorts of five participants each will be enrolled in the project. Participants will complete mSTARS, an intervention that combines inpatient skills training and the mHealth telephone app. Upon completion of the 30-day period, participants will complete self-report measures and participate in an interview designed to evaluate their experience with the mSTARS intervention.

Scaling up e-Connect in Juvenile Probation Settings

We propose to conduct research on strategies that support the successful scale-up of an evidence-based, suicidal risk and behavior identification and cross-system linkage programs for justice-involved youth (e-Connect), and to rigorously evaluate the implementation activities and associated costs that support that scale-up of e-Connect within 9 Indiana counties. Guided by the GPM and EPIS frameworks, this 4-year study will comprise 3 project phases: (1) Scale-Up Strategy Efforts, focused on preparing for scale-up; (2) e-Connect-scaleup implementation (2a Exploration and Preparation and 2b Implementation and Sustainment); and (3) Scale-Up Effectiveness Trial/Outcome Evaluation. The current project draws on lessons learned from the e-Connect efficacy trial in NYS and research team leadership will serve as External Facilitators to support 9 Local Facilitators to ensure the successful transfer of knowledge, skill and expertise in delivering e-Connect in a new JJ system and geographic context, utilizing implementation strategies to support the more widespread, sustained and rigorous adoption of e-Connect. The study will include a learning community created by External Facilitators for Local Facilitators to provide support, to exchange strategies to handle implementation issues, to develop competencies in facilitation, and to guide implementation throughout the program. The learning community will help Local Facilitators navigate through the implementation stages of the study.

Natural History of Depression, Bipolar Disorder and Suicide Risk

Mood disorders, such as depression and bipolar disorder, are difficult to treat. One reason is that there are no objective ways to measure how these disorders affect the body and respond to different treatments. In this study, researchers want to perform tests on people undergoing clinical care for mood disorders. The purpose is to understand the experience of receiving treatment for depression, bipolar disorder, and suicide risk. We also hope that this study will help us to predict which medications will improve thoughts of suicide. People 18 years or older who are receiving treatment for depression, bipolar disorder, or suicide risk may take part in this study. Participants must have also been enrolled in protocol 01-M-0254. This study will be conducted at the NIH Clinical Center in Bethesda, MD. The study typically lasts up to 12 weeks, but may last longer if a participant s treatment continues past that time. Participants will have weekly interviews and questionnaires while they are being treated for their mood disorder. Other tests are optional and include psychological testing, blood draws, sleep tests, and imaging scans. These will be done at the start and the end of research participation.

Co-Designing a Virtual Reality Intervention to Enhance Skill Development

This study is refining and pilot testing a novel Virtual Reality (VR) supplement for inpatient treatment: the Practice Experiences for School Reintegration (PrESR) program. The PrESR provides immersive school and social experiences for inpatient adolescents (with suicidal-related admissions) to practice skills in real-world settings with the guidance of a trained clinician within the confines of a hospital. The initial intervention was based on feedback from adolescent hospitalized for suicide-related crises, and school and hospital professionals, but did not provide tailored experiences to address the individual needs of ethnic-racial, gender, and sexual minoritized adolescents. Therefore, the VR environment of PrESR was adapted based on input from adolescents with previous suicide-related crises identifying as ethnic, racial, sex, or gender minoritized. This pilot randomized controlled trial (RCT) aims to explore the feasibility, acceptability, and facilitators/barriers to implementation of the adapted version of PrESR for improving outcomes in hospitalized adolescents. This study is not powered to test hypotheses; however, in addition to assessing feasibility, acceptability, and barriers/facilitators, this pilot trial will assess candidate intermediary and outcome measures.

Effectiveness and Implementation of a Clinician Decision Support System to Prevent Suicidal Behaviors

The primary aim of this project are to evaluate a comprehensive, practice-ready, and deployment-focused strategy for improving the prediction and prevention of suicide attempts among a sample of 4,000 patients presenting to an ED with a psychiatric concern. The first aim is to evaluate the effects of providing information about risk of patient suicidal behavior to ED clinicians. The investigators hypothesize that patients randomly assigned to have their clinician receive their risk score will have a lower rate of suicide attempts during 6-month follow-up and that this effect will be mediated by changes in clinician decision-making.

Emotional Prosody Recognition and Decision Making Inf fMRI and Vulnerability to Suicide

Suicide is known to be frequent in depression, and in most of the psychiatric diseases. But as it can occur in patients with no psychiatric illness and doesn't occur in every patients with psychiatric illness, it has to be considered henceforth as a specific vulnerability. This trial will study two fMRI paradigms, emotional prosody recognition and decision making, in order to characterize emotional and cognitive trait factors in a population of patients vulnerable to suicide. Four different groups will be constituted : depressed suicide attempters, depressed patients with past history of suicidal acts, depressed patients with no history of suicidal acts and healthy controls. The main goal will be to correlate fMRI activation during the two paradigms in subjects vulnerable to suicide. The secondary goals will be to characterize emotional and cognitive trait factors in these subjects, to demonstrate that those characteristics are independent from depression and to correlate these trait factors with socio-demographic and clinical features with fMRI activations.

Evaluation of a Telehealth Case Management Intervention to Prevent Suicide Among Soldiers Discharged From Psychiatric Hospitalization

This study evaluates the effectiveness of Pathfinding, a 6-month, remotely-delivered case management intervention designed to decrease suicidal behavior among active-duty Regular Army soldiers recently discharged from inpatient psychiatric treatment. Soldiers discharged from military treatment facilities across the U.S. will be identified and recruited to participate. Those who consent will be randomly assigned to receive either Treatment As Usual (TAU), which is the Army's standard post-discharge care, or TAU plus Pathfinding. Participants will complete a baseline assessment and follow-up assessments 6 months and 12 months later. The 6- and 12-month follow-up periods will also include examination of participants' electronic healthcare data and Army administrative data. The overall goals of the study are: (1) to evaluate whether Pathfinding decreases suicidal behaviors among soldiers transitioning from psychiatric hospitalization back to the community; and (2) to determine which discharged soldiers are most likely to benefit from the Pathfinding intervention versus TAU alone.

Transdiagnostic Sleep and Circadian Intervention + Bright Light in Adolescents With Elevated Depression (TranS-C+BL)

The goal of this clinical trial is to adapt a sleep intervention for individuals representative of all demographic groups, including those who are at the highest risk for suicidal behavior. Sleep difficulties are a promising target for youth with suicidal thoughts and behavior to focus on as a prevention measure. We aim to increase intervention acceptability and impact by adapting it for the adolescent populations at highest risk for suicidal thoughts and behavior. The research project will compare Transdiagnostic Sleep and Circadian Intervention (TranS-C), an evidence based, modularized intervention that targets a range of sleep difficulties to a treatment as usual or control condition including providing weekly sleep feedback reports from data entered into a daily sleep diary and from wearing a sleep sensing, actigraphy watch. Participants in both conditions (TranS-C vs. Sleep Feedback) will wear an actigraphy sleep watch that monitors sleep, and complete daily sleep diaries via smartphone or email. Participants in the TranS-C condition will also wear bright light (BL) and blue blocking glasses each day as well as attend weekly or biweekly sessions with a Sleep Therapist. The sleep therapist will review sleep feedback during sessions.
