Suicidal Ideation

The purpose of this study is to culturally adapt and evaluate an empowerment self-defense (ESD) program (i.e., IMpower) for AI/AN women who have experienced SV in their lifetime and currently experiencing moderate to severe levels of depression and/or PTSD symptoms (primary outcomes). Previous research with non-AI/AN women finds that ESD reduces depression and PTSD symptoms, but no research has examined ESD among AI/AN survivors despite calls from our tribal partners to implement ESD with AI/AN adult women survivors. The investigators have assembled an interdisciplinary expert team and Elders/Traditional Knowledge Keepers (TKKs) as well as Survivor Advisory Board (SAB) in the proposed work.

The goal of this clinical trial 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 the trial aims to answer are: * Is the EOI feasible and acceptable? * Can the EOI be delivered with fidelity by Samaritans staff? Participants will: * Receive outreach (by call or text) once per week for 12 weeks after ED visit. 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. * Be asked to complete monthly self-report questionnaires, and participate in a phone interview with study staff at the end of the study.

This study will evaluate the effectiveness of MindBridge, a dialectical behavior therapy (DBT)-informed mobile health module delivered through a WeChat mini-program, among Chinese young adults aged 18 to 24 years with mild-to-moderate suicide risk. In the randomized controlled trial, 84 participants will be randomized 1:1 to receive MindBridge plus treatment as usual or an attention-matched general well-being program plus treatment as usual for 8 weeks. Assessments will be conducted at baseline, week 4, week 8, and 1-month follow-up. The primary outcome is suicide-related thoughts and behaviors. Secondary outcomes include depression, anxiety, emotion regulation, sleep quality, perceived social support, academic self-efficacy, and problematic internet use. This randomized controlled trial is the effectiveness-evaluation component of a broader sequential mixed methods study involving the development and evaluation of MindBridge.

Young people at clinical high risk for psychosis are more likely to experience suicide thoughts than the general population, but there are few suicide prevention programs designed specifically for them. This study will develop and evaluate a recovery-oriented suicide prevention group program for young people at clinical high risk for psychosis. The program will be led by a clinician and a peer with lived experience. It will help participants identify reasons for living, build hope, set meaningful recovery goals, strengthen social connections, and learn strategies to better remember and use suicide prevention strategies developed during the program. Caregivers will also be invited to participate in a session to learn ways to support their young person. The study will first gather feedback from participants, caregivers, clinicians, and community advisors to refine the program. Researchers will then compare the program plus standard care with standard care alone to determine whether it improves personal recovery and increases participants' ability to remember and use suicide prevention strategies. Researchers will also collect feedback from participants and program staff to better understand how the program can be integrated into early psychosis services.

This protocol proposes an initial randomized clinical trial that includes all patients with suicidal ideation (SI) at baseline, and with SI as the primary outcome measure to examine whether Right Unilateral Low-Amplitude Pulse - Seizure Therapy (RUL LAP-ST) treatment has more magnitude and rate of remission of SI as conventional pulse amplitude Right Unilateral Electroconvulsive Therapy (RUL ECT) (based on our prior secondary analysis). Our central hypothesis is that RUL LAP-ST has significantly less cognitive/memory side effects (no memory side effects were noted in our prior studies for 500mA and 600mA) and thus is more favorable in terms of side effects compared to RUL conventional pulse amplitude ECT, while maintaining better anti-suicidal effect.

Sexual minority men (SMM) in Jamaica face many challenges that affect their health and well-being. Although they make up a relatively small part of the population, they are much more likely to be living with HIV than the general public. Many also experience discrimination because of their sexual orientation, HIV-related stigma, violence, poverty, unstable housing, limited educational opportunities, and barriers created by laws and social attitudes. These experiences can have a serious impact on mental health, leading to problems such as depression, anxiety, trauma, and thoughts of suicide. Many people also face barriers to getting mental health care because of stigma or a lack of services that are welcoming and appropriate for their needs. These challenges can make it difficult for people living with HIV to stay connected to medical care and take their HIV medications consistently. Missing appointments or stopping treatment can make it harder to keep the virus under control and can lead to poorer health over time. While researchers know that stigma, discrimination, and violence affect health, we still do not fully understand how these experiences work together to influence HIV care among sexual minority men in Jamaica. To help address these challenges, we developed the Gwan Enjoy Life program, a culturally relevant program designed specifically for sexual minority men living with HIV in Jamaica. The program combines practical coping skills, emotional support, and strategies for managing the effects of trauma and stress. It is led by trained peer mentors who are also living with HIV, allowing participants to learn from people who understand their experiences. The six-session program gives participants the option of meeting one-on-one with a peer mentor or participating in a small group, depending on what they find most comfortable. The program will be tested in partnership with Jamaica AIDS Support for Life (JASL), one of Jamaica's leading HIV service organizations. Sixty participants from JASL clinics in Kingston and St. Andrew, St. James, and St. Ann will take part in the intervention. Participants will be randomly assigned to either receive the Gwan Enjoy Life program or continue with their usual care, and they will be followed for one year. Researchers will examine whether the program improves mental health, strengthens social support, helps participants stay engaged in HIV care, and improves medication adherence. The goal of the intervention is to determine whether the Gwan Enjoy Life intervention is a practical and effective program that can be expanded to reach more people across Jamaica. The findings will help researchers, healthcare providers, and policymakers better understand how stigma, violence, and mental health affect HIV care and will support the development of programs that improve the health and well-being of sexual minority men living with HIV.

Since the COVID-19 pandemic, mental health disorders have increased significantly, particularly among young people. In France, the proportion of young people aged 18 to 25 suffering from depression almost doubled between 2017 and 2021. This phenomenon particularly affects students, who are already identified as being at greater risk of mental health disorders than the general population. Medical students seem to be particularly vulnerable: in 2021, a national study showed very high rates of depression and suicidal thoughts in this population. The main factor associated with depression was the feeling of financial hardship. Students often face multiple forms of insecurity. Financially, they have limited resources and struggle to cover their basic needs such as housing, food and healthcare. Socially, many experience significant isolation, particularly when they are away from their families or under pressure from their studies. All of this has a significant impact on their mental health. Unfortunately, many students do not seek help due to lack of time, resources, or awareness of support services. The 2021 study showed that only one-third of medical students suffering from depression received appropriate treatment. The aim of the study is to explore the lived experiences of the students concerned in order to identify what they perceive as the various aspects of student precarity (housing, transport, isolation, financial difficulties, etc.) and the links they perceive between these and their psychological distress. This study will deepen our understanding of these factors by exploring students' lived experiences, and will bring to light elements not identified by quantitative studies.

The goal of this clinical trial is to learn whether a combination of brief digital and clinician-delivered interventions can help adults leaving a psychiatric hospitalization cope with suicidal thoughts and prevent suicide-related events. The main questions it aims to answer are: * Are people who receive automated smartphone messages when they report suicidal thoughts after leaving the hospital less likely to have a suicide-related event than those who do smartphone self-monitoring alone? * Are people who have additional session(s) with a clinician in the four weeks after leaving the hospital less likely to have a suicide-related event than those who receive additional brief self-guided intervention(s)? Participants will be asked to: * Make a personalized safety plan (of coping strategies to use when feeling suicidal) before leaving the hospital * Do self-monitoring of suicidal thoughts and related experiences on their smartphone for four weeks after leaving the hospital * Complete a longer set of research questionnaires at the start of the study and five more times during the 12 weeks after leaving the hospital Depending on which study group they are in and whether they benefit from initial smartphone interventions, participants may or may not: * Receive automated smartphone messages reminding them of coping strategies to use for suicidal thoughts * Receive up to three additional sessions with a study clinician * Receive up to three brief online self-guided interventions The study interventions last for the four weeks after leaving the hospital. Participants will also be asked permission to share information from their health records about care received for 12 weeks after leaving the hospital.

The goal of this clinical trial is to learn whether a novel digital avatar (virtual coach) support program can help emerging adults ages 18-29 who present to the emergency department with suicidal thoughts and alcohol misuse (EA-Avatar). The study also aims to learn whether people find the program easy to use and whether daily surveys and the study design are able to be completed by the majority of emerging adult participants. The main questions this study aims to answer are: * Do participants use the digital program and find it helpful? * Is it possible for participants to complete daily surveys for twenty-eight days and follow-up surveys over twelve weeks? * Are there early signs that the program may help lower alcohol use and suicidal thoughts? Researchers will compare participants who receive the new digital avatar program plus supportive text messages to participants who receive a freely available suicide safety planning app to see if there are differences in use, engagement, and early signs of benefit. Participants will: * Receive standard care from the emergency department * Be randomly put into one of two groups (EA-Avatar or a free suicide prevention app) * Depending on their group, use a new avatar-guided digital support program with text message reminders OR use a free suicide safety planning app * Complete surveys at the start of the study and again at four, eight, and twelve weeks * Complete short daily surveys for twenty-eight days

The goal of this clinical trial is to learn if intravenous (IV) ketamine with Dialectical Behavioural Therapy (DBT) reduces suicidal ideation in individuals with suicidality who have been diagnosed with Borderline Personality Disorder and either Major Depressive Disorder or Bipolar Disorder. The main question it aims to answer is: Does IV ketamine and DBT produce more rapid and robust improvements in suicidal ideation (SI) severity between baseline and Day 35 compared to IV midazolam and DBT, as measured by changes in the Modified Scale for Suicidal Ideation (MSSI) scores ? Researchers will compare six IV ketamine infusions and DBT to an active placebo (a look-alike substance that mimics some of ketamine's effects and not others) and DBT to see if IV ketamine with DBT is more effective at reducing SI severity. Participants will: * Complete six infusions of either IV ketamine or IV midazolam * Take part in 6 months of DBT (includes both weekly one-on-one sessions, and group sessions, starting week 5 of the trial) * Visit the hospital for scheduled in-person visits * Join a call or videocall for scheduled remote visits * Complete a variety of different mood, cognitive and behavioral assessments

The goal of this randomized pragmatic clinical trial is to examine the feasibility, acceptability, and mechanisms of change of a brief adaptation of Interpersonal Psychotherapy for Adolescents (BIPT-A), adapted and task-shifted to lay providers (mentors, youth trusted adults) in youth community centers (YCCs) as an upstream approach to suicide. It focuses on Hispanic adolescents ages 12-17 enrolled in these YCCs. The pragmatic clinical trial will evaluate the acceptability and feasibility of adapted IPT-A delivered by mentors in YCCs and whether adapted BIPT-A impacts mechanisms of change (depressive symptoms, belongingness, and burdensomeness or feeling like a burden to others). The main questions to answer are: * Is adapted BIPT-A, when delivered by trained lay providers (youth mentors), feasible and acceptable in youth community centers? * Does adapted BIPT-A, delivered by lay providers, change key risk factors (i.e., key mechanisms: depressive symptoms, low belongingness, and perceived burdensomeness) associated with suicide ideation? The investigators will compare adolescents randomized to adapted BIPT-A (6 sessions) delivered by a trained youth mentor with those receiving usual services at the community center (one individual session focused on active listening). Participants will: 1. Be screened for subthreshold depression using the Patient Health Questionnaire Adolescent version (PHQ-A). Adolescent participants will be included if they score between 4 and 9 (mild depression). Participants with a PHQ-A score of 10 or higher (severe depression) will not be eligible and will be referred to a licensed mental health provider for appropriate care. 2. Be randomized to adapted BIPT-A or usual care. Adolescent participants in the intervention arm will participate in 6 weekly, adapted BIPT-A sessions with a trained youth mentor. Intervention focuses on education, affect identification, and interpersonal skills.

In this research study, investigators examine how brain activity changes during tests of emotional processing, attention, and memory using multimodal neuroimaging methods including electroencephalography (EEG), functional magnetic resonance imaging (fMRI), and functional near-infrared spectroscopy (fNIRS). Transcranial magnetic stimulation (TMS) is used to probe and modulate brain networks related to cognitive flexibility and emotion regulation. The study includes multiple related sub-studies involving healthy participants and participants with depression. Some study components focus on mechanistic modeling using non-therapeutic neurostimulation in healthy participants, while other components include interventional approaches such as individualized EEG-synchronized repetitive TMS (rTMS), cognitive tasks, and brief cognitive behavioral therapy (CBT) in participants with depression. Certain study components also evaluate CBT alone without TMS to assess behavioral intervention effects.

The researchers hope to learn whether an electronic safety plan (ESP) and a supportive text messaging program are feasible and acceptable to adult patients with recent suicidal thoughts or behavior after emergency department (ED) discharge. From this study, the researchers also hope to learn how to best carry out the ESP and text messaging program to improve outcomes for patients after ED discharge.

The goal of this clinical trial is to learn if the Along With Me web-based intervention works to decrease posttraumatic stress symptoms and suicidal ideation among bereaved parents following pregnancy and early infant loss. It will also learn whether peer guides provide additional improvements on these outcomes. The main questions it aims to answer are: • Do people who receive Along With Me or Along With Me plus a Peer Guide compared to services as usual have lower posttraumatic stress symptoms and suicidal ideation than those who do not receive the intervention? Researchers will compare Along With Me and Along With Me plus a Peer Guide to services as usual (referrals made in the hospital setting) to see if Along With Me works to prevent and address posttraumatic stress symptoms and suicidal ideation. Participants will: * Receive access to a mobile app with approximately 10 therapeutic modules about how to manage grief and other symptoms. * Receive check-ins with a Peer Guide (in the Peer Guide condition only)

This study aims to evaluate the acceptability, safety, and efficacy of a smartphone-delivered intervention called Therapeutic Evaluative Conditioning for Suicide (TEC-S) in reducing suicidal thoughts and behaviors (STB) among adults with recent and frequent suicide ideation.

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.

This study, titled "Neural Correlates of Suicidal Behavior in Youth: a Pre and Post CAMS Therapy Neuroimaging Study," aims to better understand the brain mechanisms underlying suicidal thoughts and behaviors in adolescents and young adults (ages 14-24). Suicide is a leading cause of death in this population, and current clinical approaches often fail to accurately predict or prevent suicidal behavior. This study seeks to identify objective neurobiological markers associated with suicide risk and treatment response. Participants will be divided into three groups: (1) high-risk individuals recently hospitalized following a suicide attempt, (2) medium-risk individuals with chronic suicidal ideation but no attempts, and (3) low-risk healthy controls. All participants will undergo advanced neuroimaging, including magnetoencephalography (MEG) and magnetic resonance imaging (MRI), along with comprehensive psychiatric assessments. The study focuses on brain regions and networks implicated in suicidality, including the anterior cingulate cortex and salience network, as well as neurochemical markers such as glutamate. It also examines electrophysiological activity and functional connectivity patterns associated with suicidal thoughts and behaviors. High-risk participants will receive an evidence-based psychotherapy called the Collaborative Assessment and Management of Suicidality (CAMS). This therapeutic approach emphasizes collaboration between patient and clinician to identify and address the underlying drivers of suicidal thoughts, with a focus on increasing hope and reducing psychological distress. Neuroimaging and clinical assessments will be repeated after completion of CAMS to evaluate treatment-related changes. The study's primary goals are to: * Identify neural and electrophysiological correlates of suicide risk. * Distinguish biological differences between individuals with suicidal ideation and those who have attempted suicide. * Determine how CAMS therapy affects brain function and neurochemistry. By integrating clinical and neurobiological data, this research aims to improve understanding of suicidality, enhance risk prediction, and inform more effective, personalized interventions for at-risk youth.

The purpose of this research study is to compare (vs. treatment as usual) a brief (6-session), empirically supported, and highly disseminable version of digital (i.e., smartphone or web-based) cognitive behavioral therapy for insomnia (dCBT-I), called SleepioTM, in suicidal adolescents with co-occurring insomnia during the high-risk post-hospitalization period. Suicide is the 2nd leading cause of death among adolescents. Sleep problems, such as insomnia symptoms-the most common sleep problem in youth-may be a particularly promising treatment target to reduce suicide risk in adolescents. The investigators propose to test the feasibility, acceptability, and effectiveness of dCBT-I in a two-site (Rutgers and Old Dominion University) pilot study trial. Adolescents, 14-18 years-old, recently hospitalized for suicide risk with co-occurring insomnia (n=80, 50% at each site), will receive either dCBT-I (six weekly, 20-minute sessions) plus post-hospitalization treatment-as-usual (TAU) or TAU alone. Adolescents will complete assessments pre-treatment, during the treatment phase including at the end of treatment, and 1-month follow-up post-treatment.

Suicide is a major public health concern, particularly among Veterans with serious mental illness (SMI, i.e., psychotic disorders or bipolar disorders). Wellness Recovery Action Plan (WRAP) is a well-established evidence-based practice for those with SMI that centers on identifying warning signs of mental illness, developing wellness tools for functional independence, planning for day-to-day effective living within one's community, and building an action plan to create a valued life worth living. This proposed study will refine and pilot SUicide Prevention by Peers Offering Recovery Tactics (SUPPORT), a novel integrated recovery program that is an adaptation of peer-delivered WRAP for Veterans with SMI. In SUPPORT, a Peer Specialist leads a Veteran at increased risk for suicide through recovery planning that is tailored to the Veteran's suicidal experiences with cognitive learning strategies to enhance safety plan recall and improve functioning.

The objective of this study is to test the feasibility and preliminary efficacy of Flourish (formerly referred to as imHere4U), a digital suicide prevention intervention for cyberbullied adolescents. The specific aims are to: Aim #1: Conduct a randomized controlled trial (RCT) comparing Flourish+Questionnaires vs. Questionnaires Alone among cyberbullied youth at-risk for suicide ages 12-17 (N=80, \>35% underserved youth). H2a. Primary outcome: Feasibility will be evidenced by recruitment/retention rates \> 80% and imHere4U engagement \> 70%. H2b. Secondary outcomes: Youth assigned to Flourish+Questionnaires will report improved problem-solving capacity, distress tolerance, and motivation and reduced distress and suicidal ideation than youth assigned to Questionnaires Alone over the 6-month follow-up period. Exploratory Aim: Examine the feasibility of delivering feedback on online interactions from machine learning algorithms. All youth assigned to Flourish may optionally provide their social media data to receive feedback from machine learning algorithms. H3a. Feedback from algorithms will have high acceptability (identified via qualitative themes and \>70% acceptance rates) and usability, defined by mean scores on Post-Study System and Usability Questionnaire (PSSUQ) \> 6.

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.

The goal of this pilot study is to test the effectiveness of a novel intervention for young adults (ages 18-27) with mental health conditions who have been released from an acute care psychiatric facility. The intervention aims to reduce suicidality, depression, anxiety, re-hospitalization, and improve mental health recovery by using outpatient services. The current standard of care (SOC) for these patients at discharge includes a discharge plan with a list of their medications, anticipated outpatient appointments, and information on when and where to find community resources. The intervention being tested involves the implementation of a mental health recovery education and support program, involving one-on-one and small group meetings led by Peer Support Specialists (PSS) and Recovery Community Organizations (RCO). Participants will be assigned to either Cohort A or B for 8 weeks. Cohort A will be the intervention group with PSS and RCOs. * Weeks 1-4: One-on-one meetings with PSS for education and support. Assessments will be completed at weeks 2 and 4. * Weeks 5 and 7: One-on-one meetings with PSS for education and support. * Week 6 and 8: Group meetings with PSS and other participants from RCOs. Assessments will be completed during these weeks. Cohort B will be the SOC group with no PSS or RCOs. * Weeks 1-4: Weekly check in phone calls with a member of the research team. Assessments will be completed at weeks 2 and 4. * Weeks 5-8: Check in phone calls with a member of the research team every other week. Assessments will be completed at weeks 6 and 8. Data collected from participant assessments, adherence to medication, and re-admittance to a psychiatric facility will be used to compare the intervention to the SOC.

The goal of this study is to understand why some people act more impulsively when feeling negative emotions, which is called negative urgency. The researchers hope to understand how negative urgency relates to the way networks of brain cells communicate with one another. The researchers will measure negative urgency and brain signals in adolescents aged 13-21 years with depression and suicidal thoughts and behaviors. The main questions it aims to answer are: * Whether a type of brain signaling called cortical inhibition is related to negative urgency * Whether depressed adolescents with suicidal behavior have more problems with cortical inhibition than depressed adolescents with suicidal thoughts only * Whether the relationship between negative urgency and cortical inhibition changes over time Adolescents who participate in the study will complete the following activities at the time they join the study, as well as 6 months and 12 months later: * Interviews with researchers and questionnaires to learn about their thoughts, emotions, and symptoms * A questionnaire about impulsive behaviors and negative urgency * Computerized games that measure brain functions * An MRI scan of the brain * Transcranial magnetic stimulation with electroencephalography (TMS-EEG), a way to measure how brain cells communicate (cortical inhibition) using a magnet placed outside of the head and recording brain signals

The goal of this clinical trial is to develop and test an app designed to reduce suicide risk and improve emotional well-being in adolescents. The study will test if the app's daily check ins and recommended mood boosting skills will improve the adolescent's overall mood and suicidality. The main question it aims to answer is: • Is the app practical and acceptable to use daily? In the study, adolescents will: * Participate in a focus group with other adolescents and provide feedback on the app itself (design, ease of use, etc.). * Complete surveys and assessments on their mood, thoughts, and experiences. * Complete assessments about their app experience. In the study, the legal guardian of the adolescent will: * Participate in a focus group with other adolescents and provide feedback on the app itself (design, ease of use, etc.). * Complete assessments about their app experience.

This study aims to evaluate user experiences with the online self-help course Think Life, a suicide prevention intervention for individuals experiencing suicidal thoughts. Think Life was developed by the Flemish Centre of Expertise in Suicide Prevention (VLESP) and is freely available via Zelfmoord1813.be. The course was originally developed in 2014 and updated in 2025 to improve its look and feel, usability, and inclusiveness, without fundamental changes to its core content. The researchers seek to better understand how users experience the updated version of Think Life, including perceived strengths, usability, and overall satisfaction with the course. Users of the Think Life self-help course will be invited through a call displayed on the course homepage to voluntarily participate in an online user evaluation study. Interested individuals can access an online informed consent form via a public internet link hosted on REDCap. Participants who provide online informed consent and meet the inclusion criteria will automatically be redirected to the online questionnaire, which is also hosted on REDCap. Approximately 1000 participants aged 18 years or older can be included in this study. Participants are invited to complete a one-time online questionnaire with an estimated completion time of approximately 10 minutes.
