The Marine Suicide Prevention and Intervention REsearch (M-SPIRE) study: A randomized clinical trial investigating potential treatment mechanisms for reducing suicidal behaviors among military personnel

Suicides within the U.S. Armed Forces remain elevated. Brief cognitive behavioral therapy for suicide prevention (BCBT) has demonstrated preliminary efficacy as a psychotherapeutic intervention that reduces suicide attempts among U.S. Army Soldiers. The generalizability of BCBT’s effects in other military groups and its underlying mechanisms of action remain unknown, however. The Marine Suicide Prevention and […]

Effects of the Collaborative Assessment and Management of Suicidality (CAMS) model: A secondary analysis of moderation and influencing factors

In a randomized controlled trial, we found that suicidal patients who received Collaborative Assessment and Management of Suicidality (CAMS) reported greater improvements in suicidal ideation and mental health distress compared to participants who received treatment as usual (TAU). Here, we explored moderators and mediators of the effectiveness of CAMS. Compared to TAU, CAMS was more […]

Effect of the Wingman-Connect Upstream Suicide Prevention Program for Air Force personnel in training: A cluster randomized clinical trial

Importance  Suicide has been a leading manner of death for US Air Force personnel in recent years. Universal prevention programs that reduce suicidal thoughts and behaviors in military populations have not been identified.

Systematic review of the inclusion of people with psychosis in suicide-specific clinical trials

Background: Psychosis is a significant, yet understudied, risk factor for suicide. There has yet to be a systematic investigation examining the rate and predictors of inclusion of psychotic disorders or symptoms in suicide-focused trials.

Protocol for a stepped-wedge, cluster randomized controlled trial of the LifeSpan suicide prevention trial in four communities in New South Wales, Australia

Background: Despite increasing investment in suicide prevention, Australian suicide rates have increased steadily in the past decade. In response to growing evidence for multicomponent intervention models for reducing suicide, the LifeSpan model has been developed as the first multicomponent, evidence-based, system-wide approach to suicide prevention in Australia. The LifeSpan model consists of nine evidence-based strategies. These […]

Objective  To evaluate the efficacy of dialectical behavior therapy (DBT) compared with individual and group supportive therapy (IGST) for reducing suicide attempts, nonsuicidal self-injury, and overall self-harm among high-risk youths. Design, Setting, and Participants  This randomized clinical trial was conducted from January 1, 2012, through August 31, 2014, at 4 academic medical centers. A total of 173 […]

A novel brief therapy for patients who attempt suicide: A 24-months follow-up randomized controlled study of the Attempted Suicide Short Intervention Program (ASSIP)

Background Attempted suicide is the main risk factor for suicide and repeated suicide attempts. However, the evidence for follow-up treatments reducing suicidal behavior in these patients is limited. The objective of the present study was to evaluate the efficacy of the Attempted Suicide Short Intervention Program (ASSIP) in reducing suicidal behavior. ASSIP is a novel […]

Effect of augmenting standard care for military personnel with brief caring text messages for suicide prevention: A randomized clinical trial

IMPORTANCE: Accessible and cost-effective interventions for suicidality are needed to address high rates of suicidal behavior among military service members. Caring Contacts are brief periodic messages that express unconditional care and concern and have been previously shown to prevent suicide deaths, attempts, ideation, and hospitalizations. OBJECTIVE: To test the effectiveness of augmenting standard military health […]

Efficacy of web-based collection of strength-based testimonials for text message extension of youth suicide prevention program: Randomized controlled experiment.

Background Equipping members of a target population to deliver effective public health messaging to peers is an established approach in health promotion. The Sources of Strength program has demonstrated the promise of this approach for “upstream” youth suicide prevention. Text messaging is a well-established medium for promoting behavior change and is the dominant communication medium […]

The Sources of Strength Australia Project: Study protocol for a cluster randomised controlled trial.

The school system has been identified as an ideal setting for the implementation of prevention and early intervention programs for suicide. However, in Australia, suicide-prevention programs that are routinely delivered in the schools are lacking. Internationally, evidence exists for the effectiveness of peer-led interventions that take a social connectedness approach to improve help-seeking for suicide. […]

MYPLAN – mobile phone application to manage crisis of persons at risk of suicide: Study protocol for a randomized controlled trial.

ackground Persons with a past episode of self-harm or severe suicidal ideation are at elevated risk of self-harm as well as dying by suicide. It is well established that suicidal ideation fluctuates over time. Previous studies have shown that a personal safety plan can assist in providing support, when a person experiences suicide ideation, and […]

Suicide prevention strategies revisited: 10-year systematic review.

Many countries are developing suicide prevention strategies for which up-to-date, high-quality evidence is required. We present updated evidence for the effectiveness of suicide prevention interventions since 2005. In the quest for effective suicide prevention initiatives, no single strategy clearly stands above the others. Combinations of evidence-based strategies at the individual level and the population level […]

Assessing measures of suicidal ideation in clinical trials with a rapid-acting antidepressant.

Highlights Clinical trials of ketamine and suicide will require appropriate measurement. We compared several suicide assessment measures in ketamine clinical trials. Single items and longer measures of suicidal thoughts were correlated. Items from the MADRS, BDI, and SSI may be particularly sensitive to rapid changes.
