Written Exposure Therapy for Suicide Prevention

Military service members admitted to inpatient psychiatry for self-injurious thoughts and behaviors (SITBs) represent an at-risk group for continued SITBs and rehospitalizations in the post-discharge period. However, there is an absence of evidence-based interventions designed to be delivered on inpatient psychiatric units to reduce the risk of post-discharge SITBs. To address this gap, the investigator's research group developed Written Exposure Therapy for Suicide Prevention (WET-SP), a brief, scalable, suicide-specific psychotherapy based on the written disclosure paradigm. Written disclosure, in which an individual writes about a personally stressful experience and the related thoughts and feelings, yields improvements across physical and psychiatric domains. Pilot data suggest that written exposure also yields reductions in SITBs. Yet, no study has adapted the written exposure paradigm specifically to target the amelioration of distress associated with suicidal crises and examined whether implementing WET-SP reduces the risk of subsequent SITBs and suicide-related hospitalizations. The primary objective of this randomized controlled trial (RCT) is to evaluate the efficacy of WET-SP, in reducing the incidence and severity of SITBs in active duty military service members following a psychiatric hospitalization due to suicidal ideation, suicide plans, or a suicide attempt. Secondary objectives are to evaluate a potential mechanism of change (i.e., decreases in thwarted belongingness \[cf. social disconnectedness\]) and moderator of outcomes (i.e., arc of narrative \[cf. linguistical parameters of the written narratives generated during treatment\]). Participants randomized to WET-SP + TAU will receive five sessions of WET-SP delivered by the study team during their psychiatric hospitalization plus treatment-as-usual (TAU). Participants randomized to TAU will receive daily contact and patient-centered care delivered by the acute psychiatric inpatient unit provider team (e.g., psychiatrists, therapists, case managers). TAU includes psychiatric assessment, initial stabilization, nurse case management, medication management, treatment of medical comorbidities, group and individual therapy, and discharge planning. Outcome assessments will be administered at pretreatment, posttreatment, and 10-, 20-, and 30-week follow-ups.

Effectiveness of a Case Management Algorithm: ALGOS After a Suicide Attempt

The suicidal behaviors are phenomena eminently multifactorial. It is thus always difficult to define univocal strategies of prevention of suicide repetition, during the emergency stay, i.e. almost in general population. One find 23 clinical trials in this topic in the past 25 years, and 18 are negative. The majority of the positive trials have the concern of being dissociated from an assumption of responsibility of care strictly speaking, to adopt a position "méta", nearer to the concept of "case management": how to remain in contact with the suicide attempter, without forcing it in this every day life, replacing a possible proposing, but assumption of responsibility resources reliable and quickly accessible in the event of at risk situation? Each one of these studies tests devices which seem more appropriate to such or such characteristic of this population, by retaining only simple criteria like the sex, the number of former suicide attempts, the proposal or not for an assumption of responsibility of care, the observance or not with the plan of care. Thus, it would seem interesting to combine these approaches in an algorithm entitled "ALGOS". Main aim: To test the effectiveness of this algorithm of case management, named "ALGOS", in reducing the number of death by suicide, in terms of reduction of suicide re-attempts and the number of loss of contact patients in the ALGOS group during 6 months period, compared to a control group of suicide attempters treated as usual (i.e. primarily transmitted to the attending physician). Secondary objectives: To evaluate, according to the method validated by Beecham in 1992, direct medico-economic impact in the year which follows the introduction of algorithm ALGOS. Reduction of the other suicidal behaviors in 6 months (reduction in the full number of suicidal repetitions in each group, evolution of the score of suicidal ideation, etc…). To evaluate the effect of the algorithm, at the 13th month. To study the possible differences within the time in terms of suicidal repetitions in the 2 groups. To propose different profiles of answers according to psychopathology, the number of suicide attempts, suicidal character, the sex,… Methodology: Comparative simple blind prospective multicentric controlled study

Youth Suicide and Self-Harm Intervention: Clinical and Biological Outcomes Study

The goal of this clinical trial is to develop and evaluate youth-focused intervention programs for suicide and self-harm that are tailored to the psychological, developmental, and cultural characteristics of Korean adolescents and young adults. The study examines whether two structured, mindfulness-based intervention programs-one for middle and high school students and one for young adults-reduce suicidal ideation, self-harm behaviors, depressive symptoms, and emotion-regulation difficulties. The study also aims to determine whether these clinical improvements are associated with biological changes, including alterations in resting-state functional brain activity (e.g., ALFF, ReHo, and functional connectivity) and social rhythm patterns. The main questions this study seeks to answer are: * Does the youth suicide and self-harm intervention program reduce suicidal ideation and self-injurious thoughts/behaviors? * Does the program improve mood, sleep, hopelessness, and emotion regulation? * Are improvements in clinical outcomes accompanied by changes in biological markers of suicide risk? * Researchers will compare the intervention program to usual care provided in hospitals, schools, and community mental health settings. Participants will: * Participate in the structured suicide/self-harm intervention program or receive usual care. * Complete standardized assessments of mood, sleep, emotion regulation and suicide/self-harm risk. * Undergo biological assessments, including resting-state fMRI and rhythm-related measures, at baseline and follow-up. * Be followed for up to 12 weeks.

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.

Youth Depression and Suicide Research Network

The objective of this study is to build the Texas Youth Depression and Suicide Research Network to support the development of a Network Participant Registry and characterization of systems and interventions to examine statewide population health outcomes. All 12-13 sites represented in the Texas Child Mental Health Care Consortium (https://www.utsystem.edu/pophealth/tcmhcc/) have been invited to participate in the Texas Youth Depression and Suicide Research Network as "Nodes." 12 Nodes have been selected for this project. Each Node has obtained support of senior institutional leadership including the department chair. Leadership from each Node provided input and edits in the study design process by committee, with a focus on the inclusion of the "end user" in design decisions. Nodes will work closely with the Network Hub leadership to recruit, monitor, and retain participants. This will require active engagement and sustained relationships with clinics within the academic medical center as well as clinics in the community (i.e., psychiatry, psychology, counselling).

Long-term Follow-up of Depressive Disorders in Psychiatric Care

The project investigates long-term prognosis and predictors of treatment outcomes for difficult-to-treat depression in patients in secondary psychiatric care. The current patient cohort was collected in 2012-2021 in the study "Pharmacogenetics in patients with depression with specific focus on difficult-to-treat depression, suicide attempt and CYP2D6". The cohort consists of 415 patients, examined carefully regarding diagnostic assessment and earlier treatment. All participants were also genotyped for the drug metabolizing enzymes CYP2D6 and CYP2C19. Blood samples were stored in biobank for other analyses linked to prognostic markers. The patient cohort will now be followed up with a review of medical records and extraction of register data for a period of 5 years after their participation in the original study. The purpose of the study is to improve treatment and increase knowledge about long-term prognosis in difficult-to-treat depression. This is done by examining symptom profiles, monitoring clinical course and suicidality, and examining prognostic markers.

The Group Risk Reduction Intervention Therapy (GRRIT) Project

Investigators will evaluate a group format adaptation of Brief Cognitive-Behavioral Therapy for Suicide (i.e., G-BCBT) on suicide ideation (Aim 1), ability to use coping strategies (Aim 2), and overall mental health (exploratory analysis). The combination of tailored means safety counseling and training in evidence-based emotion regulation and cognitive flexibility skills delivered via a 12-session group therapy treatment will decrease service members' overall suicide risk. The group format will provide opportunities to learn and practice skills, thereby enhancing self-efficacy. G-BCBT outcomes are expected to be no worse than Dialectical Behavior Therapy (DBT) group skills training, an existing gold standard intervention that is twice the length of time as G-BCBT.

Suicide Preventive Psychosocial Treatment for Youths

Suicide is the leading cause of death amongst 10-18-year-olds in Sweden. Suicide attempts are the strongest predictor of subsequent death by suicide, often lead to inpatient care, and are associated with substantial societal costs, making suicide attempts a critical target in psychiatric intervention research. Although youths attempting suicide are typically assessed and treated for potential comorbid psychiatric conditions, there is currently no trans-diagnostic evidence-based treatment specifically targeting suicidal behavior. To fill this gap, the Safe Alternatives for Teens and Youths (SAFETY) was developed. SAFETY is a transdiagnostic family-based cognitive-behavioral suicide prevention program that has shown promise but more studies are needed. The overall objective of this project is to evaluate the efficacy, durability, and cost-effectiveness of the SAFETY intervention, a scalable suicide prevention intervention that can be offered immediately following a youth suicide attempt, in a fully powered single-blind randomized controlled superiority trial. Our primary hypothesis is that the SAFETY intervention will be superior to Enhanced Treatment As Usual (enhanced with the evidence-based intervention safety planning) in reducing the proportion of suicide reattempts. Moreover, we predict that these improvements will be maintained for up to 60 months post-treatment. Finally, we expect that SAFETY will be cost-effective compared to the control intervention, both at the primary endpoint and in the longer term.

Drivers of Suicide Mobile App Study

The central purpose of this project is to evaluate and facilitate access to evidence-based best practices for individuals struggling with suicidal ideation and co-occurring behavioral problems, including alcohol misuse, and provide assistance to the patients while they are waiting to receive care, as they are receiving care, and after they return home. While WisePath is highly innovative in how it delivers these best practices, the content is well-established and known to reduce suicidality and alcohol misuse. We will conduct a 12-week intent-to-treat RCT with 120 suicidal adults 22 years and older who may also be experiencing alcohol misuse. Participants will be randomly assigned to WisePath (n=60) or an active control condition (n=60) including a control suicide prevention self-help app plus an electronic wellness resources brochure containing links to health and wellness materials, psychoeducation about suicide, depression, self-help recovery-focused resources (e.g., Alcoholics Anonymous and other 12-Step programs, Moderation Management, etc.), and phone/text information for the 988 Suicide \& Crisis Lifeline. Participants will be assessed at baseline, 4, 8 and 12 weeks.

Enhancing the Effectiveness of Prolonged Exposure Among Suicidal Individuals With PTSD

The long-term goal of this study is to reduce suicidal thoughts and behaviors among treatment-seeking individuals who also have posttraumatic stress disorder (PTSD). Prolonged exposure (PE) and crisis response plan (CRP) have demonstrated empirical support for reducing suicide attempts as compared to treatment as usual. However, no studies to date have assessed their effectiveness when used in combination. In light of this knowledge gap, the primary objective of this study will be to test the effectiveness of PE augmented with CRP as compared to PE with care as usual (self-guided treatment plan), an active comparator, for the reduction of suicide ideations and attempts for individuals with comorbid PTSD.

Ketamine + Cognitive Training for Suicidality in the Medical Setting

This project seeks to identify the acute and longer-term impact of a single dose of intravenous ketamine among suicidal patients referred for psychiatric consultation/liaison in the medical inpatient setting. The investigators will then test whether ketamine's rapid effects can be extended by introducing helpful information delivered by a computer-based training protocol. This work could ultimately lead to the ability to treat suicidality more efficiently and with broader dissemination by rapidly priming the brain for helpful forms of learning.

Ketamine Treatment of Youth Suicide Attempters

Ketamine, an NMDA antagonist, has been shown to have rapid anti- suicidal effects. However, its safety and efficacy and special populations has not been investigated and documented. Several reports in adults suggest rapid decrease of suicidal ideation. In the last decade there is an alarming increase of the number of suicide attempts in patients ages 14-30. Suicide is the second leading cause of death in this population. Patients with previous history of suicide attempt, are even in a higher risk category. The present study focus in this high risk group of suicide attempters. This will be a randomized controlled trial enrolling 60 youth between the ages 14-30 after a suicide attempt; patients will be randomized to receive Ketamine 0.5 mg/kg over 40 minutes or normal saline. Patients will receive all Ketamine or placebo infusions while admitted in the Inpatient Psychiatry Service. Patients will receive up to 6 ketamine or placebo infusions until, for 3 consecutive sessions, they have a clinician rated Scale for Suicidal Ideation (SSI) score of\<4, and \>50% decrease from baseline, and clinical assessment of patient not being suicidal, or they have been discharged from the inpatient unit. Patients will participate in weekly sessions of Collaborative Assessment for the management of Suicidality (CAMS), from the first week of the study while admitted to the hospital and will continue it on a weekly basis post-discharge until the patient has three consecutive outpatient CAMS sessions with an overall risk \< 2 (# 6 on the SSF Core Assessment) along with a positive response regarding their thoughts/feelings and clinician indicating behavioral stability (suicidal behavior).

Virtual Reality Lethal Means Safety Training

The goal of this randomized clinical trial is to determine whether a virtual reality (VR) training program can help healthcare providers improve their skills in discussing suicide prevention and safe storage of firearms and medications with Veterans. The study will test whether VR training increases providers' self-efficacy, confidence, and comfort in conducting lethal means safety counseling, and whether it improves their intention to use these counseling practices in their clinical work. Researchers will compare healthcare providers who complete the VR training to those who complete a 2D video training to determine whether the VR approach is more effective. Participants will complete online surveys before and after the training and again three months later. They will be randomly assigned to one of two groups: VR training group: Participants use a VR headset to interact with a virtual Veteran patient in a simulated rural clinic and practice suicide prevention counseling skills; Video training group: Participants use the same headset to watch a \~10-minute 2D video depicting the lethal means safety counseling session. After the training, participants will also provide feedback about their experience, including how realistic and useful they found the training.

A Health System/Community Partnership for Enhanced Outreach to Prevent Suicide Attempts

The goal of this study is to test an enhanced outreach intervention (EOI) delivered by Samaritans of Boston (a community organization that provides support during mental health crises) for people after they leave an emergency department (ED) visit for suicidal thoughts. The main questions it aims to answer are: * Does the EOI reduce suicide-related behaviors? * Does the EOI increase outpatient treatment attendance? * Is the EOI acceptable and feasible? * Can the EOI be delivered with fidelity by Samaritans? Participants will be randomized to the EOI plus care as usual or care as usual alone. Participants in the EOI plus care as usual group will: * Receive outreach (by call or text) at a planned time once per week for the next 12 weeks. During these conversations, Samaritans staff will ask participants questions about their suicidal thoughts and behaviors, develop and review a list of coping skills to use if they have suicidal thoughts, and discuss plans for receiving mental health care. * Receive caring messages from Samaritans staff at least once per week. * Receive standard care that hospitals give for patients who present with suicidal thoughts. * Be asked to complete monthly self-report questionnaires. For care as usual alone, participants will: * Receive standard care that hospitals give for patients who present with suicidal thoughts. * Be asked to complete monthly self-report questionnaires.

DBT Skills Groups for Veterans at High Risk for Suicide Attempt

Veteran suicide death is a national crisis. Risk factors include emotion dysregulation, which occurs across mental health disorders. Dialectical behavior therapy (DBT) is an evidence-based suicide intervention that targets emotion dysregulation but is resource-intensive and not widely available at VHA. A more efficient evidence-based DBT Skills Group (DBT-SG) is associated with reduced suicidal ideation and emotion dysregulation and likely more feasible to implement at VHA. This is a randomized controlled trial to test whether DBT-SG in addition to VHA treatment-as-usual, compared to only VHA treatment-as-usual, reduces Veteran emotion dysregulation.
