Brief cognitive-behavioral therapy effects on post-treatment suicide attempts in a military sample: results of a randomized clinical trial with 2-year follow-up

The Comprehensive Adaptive Multisite Prevention of University Student Suicide Trial: Protocol for a Randomized Controlled Trial

BACKGROUND

Suicidal ideation is increasing among university students. Despite growing demand for services, university counseling centers (UCCs) face limited resources to meet the complex needs of students who are suicidal.

OBJECTIVE

The Comprehensive Adaptive Multisite Prevention of University Student Suicide (CAMPUS) Trial evaluates 4 treatment sequences within UCCs to develop evidence-based treatment guidelines.

METHODS

The CAMPUS Trial consists of a feasibility study followed by a sequential multiple-assignment randomized trial (SMART). The original CAMPUS protocol was modified during the COVID-19 pandemic to accommodate new UCC tele-mental health services, including remote treatment, assessments, and monitoring. A smaller-scale feasibility study was conducted to (1) evaluate implementation of hybrid telehealth and in-person interventions and (2) fine-tune online procedures. Following the feasibility study, university students (aged 18-25 years) seeking UCC services with moderate to severe suicidal ideation will enroll in the CAMPUS Trial. Student participants are randomly assigned to 1 of 4 treatment sequences with 2 stages of intervention. In stage 1, students receive 4 to 6 weeks of either (1) a suicide-focused treatment-Collaborative Assessment and Management of Suicidality-or (2) enhanced treatment as usual. Treatment responders enter the maintenance phase. In stage 2, nonresponders are rerandomized for an additional 1 to 8 weeks of (1) Collaborative Assessment and Management of Suicidality or (2) an intensive skills-based treatment-dialectical behavior therapy for UCC settings. UCC counselors will enroll in the CAMPUS Trial to complete measures about their experience working with students who are suicidal. CAMPUS Trial administration includes representation from all sites to facilitate cross-site coordination and an advisory board of stakeholders from all UCCs to facilitate treatment implementation.

RESULTS

Student participant recruitment began on October 25, 2022, and ended on May 16, 2024. As of November 2024, data collection for the SMART was ongoing with active study participants. Data collection was completed in November 2024, and as of April 2025, data analysis is underway. Full results will be available in 2025.

CONCLUSIONS

The CAMPUS Trial offers a model for future SMARTs for the treatment of suicidal thoughts or behaviors (or both) across various settings. The results will inform treatment guidelines for students presenting with suicidality at UCCs.

Randomized controlled trial for the Attempted Suicide Short Intervention Program (ASSIP): An independent non-replication study

Following the call for rigorous replication practices in crisis intervention and suicide prevention research, this study re-evaluated the efficacy of a brief intervention (ASSIP - Attempted Suicide Short Intervention Program) for patients with a recent suicide attempt in reducing repeated suicidal behavior. In this open-label, randomized, controlled parallel-group trial, 92 patients were assigned to treatment as usual (TAU) or TAU plus ASSIP. The primary outcome was suicidal behavior (suicide attempts and suicide deaths) during a 12-month observation period. Secondary outcomes included the number of suicide attempts and psychiatric inpatient admissions. Twelve patients in the intervention group and six patients in the control group engaged in suicidal behavior, including one suicide death in each group. The intention-to-treat (ITT) analysis found no significant effect of ASSIP in reducing suicidal behavior or admission to psychiatric hospitals. Surprisingly, the per-protocol (PP) analysis revealed a significantly higher incidence rate of suicide re-attempts in the intervention group. Contrary to the original findings, this non-replication study suggests that ASSIP combined with TAU does not significantly reduce suicidal behavior compared to TAU alone. Further research is needed to refine indications for ASSIP therapy and enhance its effectiveness.

Making Progress in Clinical Trials for Suicide Prevention: A Review

Importance

Suicide is a public health crisis, and despite renewed efforts to confront this problem, suicide rates continue to rise in the US. While suicide prevention encompasses a broad array of strategies, treatment development is lagging. Within this realm, clinical trials are the criterion standard for evaluating safety and efficacy of new treatments.

Observations

Most clinical trials conducted among patients with mental illness have excluded patients at risk of suicide. Historical reasons for this include regulatory challenges, liability concerns, ethical questions, discomfort working directly with high-risk patients, and the belief that research is too risky for individuals at elevated risk for suicide.

Conclusions and Relevance

Several considerations are provided for investigators in the design of trials targeting at-risk populations, including thoughtful selection of study outcome, use of time-to-event design and analysis (which may simultaneously satisfy ethical concerns and scientific aims), enrolling an enriched sample (eg, among patients recently discharged from the hospital), and provision of usual care in the comparator group. Caution should be exercised to avoid excessive or unreasonable safety requirements, which may lead participants to minimize self-report of suicidal ideation or to drop out of trials. Where possible, regulatory bodies (institutional review boards [IRBs] and data and safety monitoring boards) should consult with or include as members those with direct clinical experience with this high-risk population. An important ethical principle for IRB members and other regulators to consider is that suicide-related events are expected in this clinical population.

Conditions that increase the perceived likelihood of temporary restriction of firearm access: An investigation in male firearm owners

INTRODUCTION

This study evaluated hypothetical participation in temporary voluntary removal of firearms from the home to reduce future suicide risk in 408 adult male firearm owners.

METHODS

A delay discounting approach was applied to evaluate the degree to which these choices were influenced by two dimensions of reinforcer efficacy-delay and magnitude. The decision-making task sampled choice behavior across various durations of temporary voluntary removal of firearms (Delay) and differences in stated potential risk of suicide (Magnitude) as a result of that choice.

RESULTS

Results of mixed-effects modeling indicated that the subjective value of immediate access to a firearm was differentially sensitive to both delay and magnitude. Additionally, the scaling of these effects was linked to various other indicators of firearm-specific safety (e.g., use of trigger locks) and suicidality risk (e.g., intolerance of uncertainty).

CONCLUSIONS

These results provide additional support for behavioral models of decision-making (i.e., delay discounting) when evaluating how specific environmental arrangements and framing may support (or potentially discourage) engagement in means safety activities, inclusive of temporary firearms access restriction. These findings suggest that further analysis of the ecological underpinnings of these choices may help to guide more targeted efforts to engage with firearm owners in safety planning when there are concerns about the potential for suicide.

Assessment and Management of Patients at Risk for Suicide: Synopsis of the 2024 U.S. Department of Veterans Affairs and U.S. Department of Defense Clinical Practice Guidelines

DESCRIPTION

The U.S. Department of Veterans Affairs (VA) and U.S. Department of Defense (DOD) updated the 2019 joint clinical practice guideline (CPG) for assessing and managing patients who are at risk for suicide. This synopsis provides primary care physicians with a summary of the updated 2024 recommendations regarding evaluation and management of military members and veterans at risk for suicide.

METHODS

In 2023, the VA/DOD Evidence-Based Practice Work Group convened to develop a joint VA/DOD guideline, including clinical stakeholders, which conformed to the National Academy of Medicine's tenets for trustworthy CPGs. The Work Group drafted 12 key questions, reviewed systematically identified literature (1 April 2018 to 15 March 2023), evaluated the evidence, created algorithms, and advanced 24 recommendations in accordance with the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system.

RECOMMENDATIONS

Despite insufficient evidence to recommend for or against suicide risk screening programs as a means for reducing suicide attempts or deaths, the VA/DOD Work Group identified validated tools that could be used to identify populations at higher risk for suicide-related behaviors. Cognitive behavioral therapy was also recommended for reducing the risk for suicide attempts and decreasing suicidal ideation among those with a history of suicidal behavior or a history of self-directed violence. Periodic communications after previous suicide attempts were also recommended as a prevention strategy. Pharmacologic treatments, such as clozapine or ketamine infusion, also have a role in the management of suicide risk among those with schizophrenia or major depressive disorder, respectively.

A Preliminary Outcome Study of Brief Cognitive Therapy for Management of Suicidal Thoughts and Behaviors: An Open-label Trial Protocol

Background

Suicidal thoughts and behaviors (STBs) are a major concern in India, but there is limited research on effective interventions. Cognitive Therapy for Suicidal Patients (CT-SP) has shown promise, but its implementation in India needs further investigation.

Novelty

This study adopts a transdiagnostic approach to suicidality, recognizing the strong link between various mental health conditions and STBs. The study aims to use an evidence-based intervention for acute suicidal risk and understand its outcomes in the Indian context using systematic implementation. The blended delivery format of the intervention (both in-person and online) further enhances its relevance for diverse clinical settings.

Objectives

The study aims to assess the effectiveness of a brief CT-SP intervention in reducing the severity of suicidal ideation and behaviors. Secondary objectives include evaluating changes in emotional regulation, cognitive flexibility, hopelessness, depression, anxiety, problem-solving skills, frequency of dysfunctional cognitions, and overall functioning.

Methods

The study will use an open-label, single-group design with baseline, post-intervention, and follow-up assessments at one, three, and six months. Patients with recent suicidal ideation or behaviors will be recruited across diagnoses. The intervention consists of a ten-session CT-SP protocol delivered in a blended format over five weeks.

Expected Outcome

The study would contribute to the empirical understanding of suicide risk management in clinical settings and inform the development of culturally relevant interventions specific to the Indian context.

The Interaction Between Alcohol Misuse and Belongingness on Suicidal Ideation Among Military Personnel

Previous research suggests a high prevalence of suicidal ideation among military personnel. Suicidal ideation is associated with suicide attempts and death. This study focused on the association between belongingness-a component of the Interpersonal Psychological Theory of Suicide-and alcohol misuse on suicidal ideation among the different categories of military branch and military service status. Using the Military Suicide Research Consortium Common Data Elements database (N = 2516), we conducted linear regression analyses to examine the moderating effect of belongingness and alcohol misuse on the association between military branch and military service status (i.e., Active Duty) on suicidal ideation. Results showed a negative significant association between belongingness and suicidal ideation, and a positive significant association between alcohol and suicidal ideation. The results indicated that alcohol misuse moderated the association between military branch and suicidal ideation, but did not moderate the association between military service status and suicidal ideation. Additionally, the results indicated that belongingness moderated the association between military branch and suicidal ideation and the association between military service status and suicidal ideation. The results highlight the differences across military branches and military service statuses and suggest the importance of developing tailored suicide prevention programs to address the specific needs of each military subpopulation.

Understanding Compliance Rates in Suicide Research During the Post-Discharge Period

INTRODUCTION

The period following discharge from psychiatric hospitalization is one of particularly elevated suicide risk. It is essential to better understand risk factors for suicide during this period; however, retention and compliance in longitudinal research can be a challenge with high-risk populations.

METHODS

We examined compliance rates in the six-month period following psychiatric hospital discharge among 174 adults (149 psychiatric patients and 25 healthy controls) across three data collection methods: ecological momentary assessment (EMA), weekly clinical assessment phone calls, and clinical follow-up assessments at two- and six-months post-discharge. We examined whether clinical and demographic characteristics influenced compliance rates.

RESULTS

Results suggested low rates of EMA compliance, but strong rates of completion of weekly phone calls and follow-up assessments. Compared to psychiatric patients, healthy controls completed more EMA and weekly phone calls, but not follow-up assessments. Participants who met current diagnostic criteria for a major depressive episode and who scored above the clinical threshold for borderline personality disorder symptoms had lower EMA compliance rates.

CONCLUSIONS

These findings have important implications for strategies to improve patient engagement in research during this high-risk period.

Profiles of Decision-Making and Suicidal Behaviors

OBJECTIVE

Deficits in decision-making (DM) are a significant risk factor for suicidal behaviors. However, specific patterns of DM aspects have rarely been examined. This study examined the profiles of DM and their relationship with suicide ideation and attempts.

METHODS

A total of 175 young adults participated in an online survey and the Cambridge Gambling Task between October and November 2021.

RESULTS

Based on the latent profile analysis with four aspects of DM-risk DM, risk adjustment, DM speed, and delay-discounting-as indicators, three profiles were identified: (1) no deficit class, (2) high risk DM class, and (3) slow DM speed class. Higher use of an avoidant and dependent DM styles was associated with a greater likelihood of being in the slow DM speed class. Younger age and psychache was associated with a greater likelihood of being in the high risk DM class. The rates of lifetime suicide ideation (i.e., wish for death, suicide intent, and suicide plan) and lifetime suicide attempt were higher in the high risk DM class than in the no deficit class. The rate of lifetime wish for death was higher in the slow DM speed class than in the no deficit class.

CONCLUSIONS

Suicide prevention may benefit from addressing DM, which is characterized by high risk and slow speed.

Borderline Personality Traits Do Not Moderate the Relationship Between Depression, Beliefs, and Suicidal Thoughts and Behaviors

Adults with clinically significant borderline personality disorder traits (BPTs) are at high risk of experiencing suicidal thoughts and behaviors (STBs). STBs among those with BPTs have been associated with suicidal beliefs (e.g., that one is unlovable or that distress is intolerable). However, the extent to which suicidal beliefs uniquely mediate the relationship between emotional distress and STBs among individuals with BPTs is not known. Individuals admitted to an inpatient unit (N = 198) with recent STBs completed assessments of BPTs, depression, suicidal beliefs, suicidal ideation, and suicide attempt history. Moderated mediation models were used to explore whether suicidal beliefs mediated the relationship between depression and STBs conditional on BPTs. Suicidal patients with versus without BPTs reported stronger suicidal beliefs and more severe STBs (i.e., suicidal ideation, lifetime attempts). Exploratory moderated mediation analysis demonstrated that suicidal beliefs mediated the relationship between depression and suicidal ideation as well as suicide attempts. The mediation effect of suicidal beliefs on the depression-ideation and depression-attempt relationship was not significantly moderated by BPTs. This study was cross-sectional and therefore the estimated mediation models must be considered exploratory. Longitudinal research will be needed to assess the potential causal mediation of suicidal beliefs on the relationship between depression and STBs. The results of this study suggest that suicidal beliefs may play a significant role in the relationship between depression and STBs for inpatients with a history of suicidality regardless of BPTs. This suggests suicidal beliefs may be an important treatment target for adults with a history of STBs.

Initial evaluation of a personalized advantage index to determine which individuals may benefit from mindfulness-based cognitive therapy for suicide prevention

OBJECTIVE

Develop and evaluate a treatment matching algorithm to predict differential treatment response to Mindfulness-Based Cognitive Therapy for suicide prevention (MBCT-S) versus enhanced treatment-as-usual (eTAU).

METHODS

Analyses used data from Veterans at high-risk for suicide assigned to either MBCT-S (n = 71) or eTAU (n = 69) in a randomized clinical trial. Potential predictors (n = 55) included available demographic, clinical, and neurocognitive variables. Random forest models were used to predict risk of suicidal event (suicidal behaviors, or ideation resulting in hospitalization or emergency department visit) within 12 months following randomization, characterize the prediction, and develop a Personalized Advantage Index (PAI).

RESULTS

A slightly better prediction model emerged for MBCT-S (AUC = 0.70) than eTAU (AUC = 0.63). Important outcome predictors for participants in the MBCT-S arm included PTSD diagnosis, decisional efficiency on a neurocognitive task (Go/No-Go), prior-year mental health residential treatment, and non-suicidal self-injury. Significant predictors for participants in the eTAU arm included past-year acute psychiatric hospitalizations, past-year outpatient psychotherapy visits, past-year suicidal ideation severity, and attentional control (indexed by Stroop task). A moderation analysis showed that fewer suicidal events occurred among those randomized to their PAI-indicated optimal treatment.

CONCLUSIONS

PAI-guided treatment assignment may enhance suicide prevention outcomes. However, prior to real-world application, additional research is required to improve model accuracy and evaluate model generalization.

The influence of psychotherapy on individuals who have attempted suicide: A systematic review and meta-analysis

INTRODUCTION

Suicide is a serious global public health issue, and a history of attempted suicide is the most critical indicator of suicide risk. There are limited studies on the effectiveness of psychotherapy in individuals who have attempted suicide, and other outcome measures related to suicide risk in suicide attempts have not been explored.

AIM/QUESTION

This study aimed to systematically review and perform a meta-analysis of the effectiveness of psychotherapy on individuals who have attempted suicide.

METHODS

This study conducted a comprehensive literature search of five major databases (PubMed, EMBASE, Cochrane, Web of Science, and Ovid). The protocol for this study is registered with PROSPERO (CRD42023464401) and follows the PRISMA guidelines.

RESULTS

This meta-analysis included a total of 34 trials from 32 literature sources. The study involved a total of 6600 participants. The results showed that psychotherapy had a positive effect on reducing the suicidal tendencies of individuals who have attempted suicide and effectively reduced the number of repeated suicide attempts as well as the levels of suicidal ideation, depression, anxiety and hopelessness.

IMPLICATIONS FOR PRACTICE

This study concludes that psychotherapy is effective in reducing the suicidal tendencies of individuals who have attempted suicide. Psychological therapy for individuals who have attempted suicide are crucial in preventing future suicidal behaviours.

Brief Cognitive Behavioral Therapy for Suicidal Inpatients: A Randomized Clinical Trial

Importance

Suicide risk is elevated after discharge from inpatient level of care. Empirically supported inpatient suicide prevention treatments are needed.

Objective

To determine whether adding an inpatient version of brief cognitive behavioral therapy for suicide prevention to treatment as usual reduces postdischarge suicide attempts, suicidal ideation, and psychiatric readmissions and to determine whether substance use disorder moderates treatment effects.

Design, Setting, and Participants

This randomized clinical trial compared treatment as usual (n = 106) to treatment as usual plus brief cognitive behavioral therapy for inpatients (n = 94) at a private psychiatric hospital in Connecticut. Follow-up assessments were completed monthly for 6 months postdischarge. Participants were enrolled from January 2020 through February 2023. Inpatients admitted following a suicidal crisis (past-week suicide attempt or ideation with plan on admission and attempt within previous 2 years) were included. Medical records of consecutive admissions (n = 4137) were screened, 213 were study eligible and randomized, and 200 were analyzed. A total of 114 participants (57.0%) completed 6-month follow-up assessments. Data from medical records were also obtained through 6-month follow-up.

Intervention

Up to 4 individual sessions of brief cognitive behavioral therapy for suicide prevention designed for inpatients.

Main Outcomes and Measures

Suicide attempts and readmissions were assessed via blind interviews and medical record review. Suicidal ideation was assessed via self-report.

Results

The mean (SD) age among 200 analyzed participants was 32.8 (12.6) years; 117 participants were female and 83 were male. Brief cognitive behavioral therapy-inpatient reduced the occurrence of suicide attempt over 6 months postdischarge by 60% (odds ratio, 0.40; 95% CI, 0.20-0.80; number needed to treat, 7) in the entire patient group, and the rate of psychiatric readmissions by 71% (rate ratio, 0.29; 95% CI, 0.09-0.90) in those without a substance use disorder. The effect of treatment condition on suicidal ideation was less clear, although post hoc analyses indicated less severe suicidal ideation following brief cognitive behavioral therapy-inpatient vs treatment as usual at 1 and 2 months postdischarge.

Conclusions and Relevance

Brief cognitive behavioral therapy-inpatient reduced 6-month postdischarge suicide reattempts and rate of readmissions when added to treatment as usual. Substance use disorder moderated the treatment's effect on readmission rates. Treatment effects on suicidal ideation were less clear. Implementation research is needed to facilitate dissemination. Additional research is also needed to optimize outcomes for individuals with substance use disorders.

Telehealth Brief Cognitive Behavioral Therapy for Suicide Prevention: A Randomized Clinical Trial

Importance

Suicide rates continue to increase in the US. Evidence-based treatments for suicide risk exist, but their effectiveness when delivered via telehealth remains unknown.

Objective

To test the efficacy of brief cognitive behavioral therapy (BCBT) for reducing suicide attempts and suicidal ideation among high-risk adults when delivered via telehealth.

Design, Setting, and Participants

This 2-group parallel randomized clinical trial comparing BCBT with present-centered therapy (PCT) was conducted from April 2021 to September 2023 with 1-year follow-up at an outpatient psychiatry and behavioral health clinic located in the midwestern US. Participants reporting suicidal ideation during the past week and/or suicidal behavior during the past month were recruited from clinic waiting lists, inpatient service, intermediate care, research match, and direct referrals from clinicians. A total of 768 participants were invited to participate, 112 were assessed for eligibility, and 98 were eligible and randomly assigned to a treatment condition. Data analysis was from April to September 2024.

Interventions

Participants received either BCBT, an evidence-based suicide-focused treatment that teaches emotion regulation and reappraisal skills, or PCT, a goal-oriented treatment that helps participants identify adaptive responses to stressors. Participants were randomized using a computerized stratified randomization algorithm with 2 strata (sex and history of suicide attempts).

Main Outcomes and Measures

The primary outcome was suicide attempts as measured by the Self-Injurious Thoughts and Behaviors Interview-Revised. The secondary outcome was severity of suicidal ideation as measured by the Scale for Suicide Ideation.

Results

Participants included 96 adults (mean [SD] age, 31.8 [12.6] years; 64 female [66.7%] and 32 male [33.3%]), with 51 receiving BCBT and 45 receiving PCT. Of all participants, 85 (88.5%) completed at least 1 session. From baseline to 12 months, 12 participants receiving PCT (estimated percentage, 35.6%) made 56 suicide attempts and 11 participants receiving BCBT (estimated percentage, 30.0%) made 36 suicide attempts. Participants randomized to BCBT made significantly fewer suicide attempts than participants randomized to PCT (mean [range], 0.70 [0.00-8.00] attempts per participant vs 1.40 [0.00-10.00] per participant) and had a 41% reduced risk for suicide attempts (hazard ratio, 0.59; 95% CI, 0.36-0.96; P = .03). Severity of suicidal ideation significantly decreased in both treatments (F4,330 = 50.1; P < .001) but did not differ between groups (F4,330  = 0.2; P = .91).

Conclusions and Relevance

The findings of this randomized clinical trial suggest that BCBT delivered via video telehealth is effective for reducing suicide attempts among adults with recent suicidal thoughts and/or behaviors.

The impact of neural emotion reactivity and regulation on the association between depression and suicide ideation in high-risk adults

BACKGROUND

Depression is closely related to suicidal ideation (SI); however, it is unclear who is most vulnerable to SI within the context of depression. Research suggests that individual differences in emotion reactivity and regulation may be potential moderators of the link between depression and SI. Therefore, the current study tested this hypothesis using objective markers of emotion reactivity and volitional cognitive regulation capacity during functional magnetic resonance imaging (fMRI).

METHODS

Adults (n = 91) with active SI completed validated self-report measures of current depressive symptoms and SI severity. Participants completed an fMRI task designed to probe neural response to aversive stimuli and during cognitive reappraisal - a form of volitional emotion regulation. Activation of the amygdala during aversive emotion reactivity was measured. Activation of ventrolateral, dorsolateral, and dorsomedial prefrontal cortex (vlPFC, dlPFC, and dmPFC) during cognitive reappraisal were also measured. A series of hierarchical linear regressions testing the unique and interactive effects of depression symptoms and neural activation on severity of SI were conducted.

RESULTS

Analyses revealed a depression x amygdala activation interaction. The positive association between depression and SI severity was more robust in the context of high amygdala reactivity than low amygdala reactivity. Analyses also indicated there was no PFC activity (neural cognitive reappraisal) by depression interaction.

LIMITATIONS

Psychoactive medications were allowed and all participants endorsed suicidal intent.

CONCLUSION

Strategies aimed at targeting exaggerated emotion reactivity within the context of depression may be beneficial.

Facets of Suicidal Ideation

According to SAMHSA (2023), approximately 16,600,000 American adults and teens reported having serious thoughts of suicide in 2022. While suicide prevention has primarily focused on suicide deaths and attempts, we contend that suicidal ideation (SI) deserves more in-depth investigation and should be an essential intervention target on its own. In support of this point, we provide three examples of ways to improve specificity in understanding of SI through the study of controllability of SI, the language used to assess SI, and measuring SI in real time. We also consider qualitative work on the content of SI, its treatment, and definitional considerations. We thus call for an increased general focus on SI within research, clinical care, and policy.

Predicting Suicides Among US Army Soldiers After Leaving Active Service

Importance

The suicide rate of military servicemembers increases sharply after returning to civilian life. Identifying high-risk servicemembers before they leave service could help target preventive interventions.

Objective

To develop a model based on administrative data for regular US Army soldiers that can predict suicides 1 to 120 months after leaving active service.

Design, Setting, and Participants

In this prognostic study, a consolidated administrative database was created for all regular US Army soldiers who left service from 2010 through 2019. Machine learning models were trained to predict suicides over the next 1 to 120 months in a random 70% training sample. Validation was implemented in the remaining 30%. Data were analyzed from March 2023 through March 2024.

Main outcome and measures

The outcome was suicide in the National Death Index. Predictors came from administrative records available before leaving service on sociodemographics, Army career characteristics, psychopathologic risk factors, indicators of physical health, social networks and supports, and stressors.

Results

Of the 800 579 soldiers in the cohort (84.9% male; median [IQR] age at discharge, 26 [23-33] years), 2084 suicides had occurred as of December 31, 2019 (51.6 per 100 000 person-years). A lasso model assuming consistent slopes over time discriminated as well over all but the shortest risk horizons as more complex stacked generalization ensemble machine learning models. Test sample area under the receiver operating characteristic curve ranged from 0.87 (SE = 0.06) for suicides in the first month after leaving service to 0.72 (SE = 0.003) for suicides over 120 months. The 10% of soldiers with highest predicted risk accounted for between 30.7% (SE = 1.8) and 46.6% (SE = 6.6) of all suicides across horizons. Calibration was for the most part better for the lasso model than the super learner model (both estimated over 120-month horizons.) Net benefit of a model-informed prevention strategy was positive compared with intervene-with-all or intervene-with-none strategies over a range of plausible intervention thresholds. Sociodemographics, Army career characteristics, and psychopathologic risk factors were the most important classes of predictors.

Conclusions and relevance

These results demonstrated that a model based on administrative variables available at the time of leaving active Army service can predict suicides with meaningful accuracy over the subsequent decade. However, final determination of cost-effectiveness would require information beyond the scope of this report about intervention content, costs, and effects over relevant horizons in relation to the monetary value placed on preventing suicides.

Gender differences in risk and resilience for suicidal thoughts and behaviors: A national longitudinal survey study of United States veterans with a recent suicide attempt

BACKGROUND

This study reports on gender differences in psychosocial symptoms and suicidal thoughts and behaviors from the first longitudinal, national survey of veterans with a recent nonfatal suicide attempt to inform women-tailored suicide prevention.

METHODS

We recruited all female veterans with a documented nonfatal suicide attempt between October 2018 and September 2019 and a stratified matched sample of males. Surveys were administered at baseline, month 6, and month 12; 968 veterans completed the baseline survey with valid gender data. Surveys assessed psychosocial constructs, suicidal ideation severity, and suicidal behavior. Administrative datasets provided healthcare and suicide attempt data during the one year follow up.

RESULTS

Women retained higher social rejection and institutional betrayal, and lower self-compassion and autonomy than men over follow up. Higher overall self-compassion was associated with lower baseline suicide ideation for both women and men; however, this association was stronger for women (Δ = -0.19; 95 % CI = -0.31, -0.07; d = -0.15). Individuals with higher overall psychological distress had greater odds of a subsequent suicide attempt (AOR = 2.20, 95 % CI = 1.56, 3.11). Social rejection had the strongest association with worsening psychological distress, both within individuals (b = 0.18; 95 % CI = 0.14, 0.23; d = 0.23) and between individuals (b = 0.07; 95 % CI = 0.04, 0.10; d = 0.09).

LIMITATIONS

Results may not generalize beyond a VHA-utilizing veteran population.

CONCLUSIONS

Findings from this study inform potential therapeutic targets and topics for future research on tailoring suicide prevention for women veterans. While all veterans may need support reducing distress, women may need additional support in multiple other areas.

Client-reported impact of the Attempted Suicide Short Intervention Program

BACKGROUND

A history of attempted suicide is the most significant predictor of suicidal death. Several brief interventions aimed at tertiary suicide prevention have been investigated in clinical trials. However, suicide attempt survivors' experiences of such interventions have rarely been reported.

OBJECTIVE

To explore how suicide attempt survivors perceive the impact of the Attempted Suicide Short Intervention Program (ASSIP).

METHOD

We interviewed 14 Finnish adults who had received ASSIP as an adjunct to treatment as usual. Semi-structured interviews took place 4-10 weeks after the last ASSIP session. A conventional content analysis of the interview data is presented.

RESULTS

Three core categories depicting ASSIP's perceived impact were identified. The core category life-affirming change comprised subcategories of feeling better, thinking differently, acting differently, and having new resources. The core category collateral effects comprised difficult feelings and cognitive overload. The core category incompleteness of change comprised lack of desired change, gains as incomplete, need for sustenance, and unrealized potential.

CONCLUSION

Clients perceived ASSIP as effectively facilitating life-affirming change but agreed that further support was necessary to retain and build on these gains. Identified needs for improvement included more predictable post-ASSIP service paths and more support for involving affected loved ones.

The Components and Characteristics of Safety Management Plans Used to Reduce the Risk of Self Harm: A PRISMA Scoping Review

BACKGROUND

The term "safety management planning" can be thought of as having evolved to constitute a number of different intervention types and components used across various clinical settings with various populations. This poses a challenge for effective communication between clinicians and likely variability in the clinical effectiveness of these interventions.

AIM

This PRISMA Scoping Review aims to review the literature to ascertain which intervention components and characteristics currently fall under this umbrella term as well as in which contexts the plans are delivered and who is involved in the process.

METHOD

Published research studies in PsycINFO, CINAHL Plus, MEDLINE, Science Direct and Web of Science were reviewed. Grey literature was searched using the databases Base and OpenGrey as well as through the search engine Google.

RESULTS

2853 abstracts were initially identified for screening and 74 pieces of literature informed the final review, with 54 derived from the published academic literature and 20 from the grey literature. Results indicated that the safety plans are used with a wide variety of populations and often include components related to identifying warning signs, internal coping strategies, accessing social professional support amongst other components.

CONCLUSION

Although most safety management plans described appeared to be based on specific interventions, there was a large amount of heterogeneity of components and characteristics observed. This was particularly the case with regards to safety management planning within the grey literature.

Suicide-Specific Cognitions and Suicidal Behavior in U.S. Military Veterans

BACKGROUND

U.S. military veterans may be reluctant to disclose suicidal thoughts and behaviors. Suicide-specific cognitions, which generally avoid direct mention of suicide, may be reliable indicators of risk among those reluctant to disclose such thoughts and behaviors.

METHODS

Data from a population-based, cross-sectional study of 2,430 U.S. military veterans were analyzed to examine the associations between the Brief Suicide Cognitions Scale (B-SCS), suicidal ideation, and suicide planning.

RESULTS

After adjusting for age, sex, number of adverse childhood experiences, cumulative trauma burden, depressive symptom severity, and lifetime history of suicide attempt, total scores on the B-SCS (excluding the item mentioning suicide) were uniquely associated with suicidal ideation (odds ratio [OR] = 1.23, 95% confidence interval [CI] = 1.15-1.32) and suicide planning (OR = 1.27, 95%CI = 1.18-1.37). Exploratory post-hoc analyses revealed that difficulties with solving and coping with one's problems were uniquely linked to these outcomes.

CONCLUSIONS

Assessment of suicide-specific cognitions may help to enhance suicide detection and prevention in veterans, especially in those who may not directly disclose thoughts of suicide. Intervention efforts to bolster perceived deficits in coping and problem-solving may help mitigate suicide risk in this population.

Social Support and Social Stress Among Suicidal Inpatients at Military Treatment Facilities: A Multidimensional Investigation

ABSTRACT

The associations between social support and stress with internalizing symptoms (depressive symptoms and hopelessness) and hazardous drinking were tested in an inpatient sample of suicidal military personnel. Baseline data from a randomized clinical trial were analyzed. Different sources of support and stressors in the social context of military personnel were differentially linked to internalizing symptoms and hazardous drinking. In the full sample ( n = 192), family and nonfamily support were both inversely associated with internalizing symptoms but not hazardous drinking. Family stress was positively associated with internalizing symptoms. In a subsample of service members who had a history of deployment ( n = 98), postdeployment social support was protective against internalizing symptoms, whereas deployment harassment was associated with increased odds of hazardous drinking. Results underscore the need for assessment of various dimensions of social support and stress to guide case formulation and optimize strategies to support patients' mental well-being and adaptive coping.

A call to action: informing research and practice in suicide prevention among individuals with psychosis

Although it is well established that individuals living with psychosis are at increased risk for suicidal ideation, attempts, and death by suicide, several gaps in the literature need to be addressed to advance research and improve clinical practice. This Call-to-Action highlights three major gaps in our understanding of the intersection of psychosis and suicide as determined by expert consensus. The three gaps include research methods, suicide risk screening and assessment tools used with persons with psychosis, and psychosocial interventions and therapies. Specific action steps to address these gaps are outlined to inform research and practice, and thus, improve care and prognoses among persons with psychosis at risk for suicide.

Non-pharmacological interventions for preventing suicide attempts: A systematic review and network meta-analysis

Suicide attempts can cause serious physical harm or death. It would be crucial to gain a better understanding of the comparative efficacy of non-pharmacological interventions. We aimed to identify which non-pharmacological interventions are more effective in preventing suicide attempts. PubMed, Web of Science, and EMBASE databases were searched systematically from their inception until 3 April 2023. To be eligible for inclusion, randomized controlled trials (RCTs) had to meet the following criteria: Participants were individuals who had suicidal ideation or a history of severe self-harm or attempted suicide. A network meta-analysis was performed using a random effects model to estimate the treatment effect of various non-pharmacological interventions. (PROSPERO registration number: CRD42023411393). We obtained data from 54 studies involving 17,630 participants. Our primary analysis found that Cognitive therapy (CT) (OR=0.19, 95%CI =0.04-0.81), Dialectical Behavior Therapy (DBT) (OR=0.37, 95%CI =0.13-0.97), Cognitive-behavioral therapy (CBT) (OR=0.42, 95%CI =0.17-0.99), and Brief intervention and contact (BIC) (OR=0.65, 95%CI=0.44-0.94) were superior to TAU (within the longest available follow-up time) in preventing suicide attempts, while other intervention methods do not show significant advantages over TAU. Secondary analysis showed that the two intervention measures (CT and BIC) were effective when follow-up time did not exceed 6 months, but there was no effective intervention measure with longer follow-up times. CT, DBT, CBT, and BIC have a better effect in preventing suicide attempts than other non-pharmacological interventions. Additional research is necessary to validate which interventions, as well as which combinations of interventions, are the most effective.

Crisis response planning rapidly reduces suicidal ideation among U.S. military veterans receiving massed cognitive processing therapy for PTSD

Posttraumatic stress disorder (PTSD) is common among U.S. military veterans and is associated with increased risk of suicidal thoughts and behaviors. Crisis response planning (CRP), a brief safety planning-type intervention, has been shown to rapidly reduce suicidal ideation and suicide attempts in emergency and acute care settings. CRP's effectiveness when combined with trauma-focused therapies remains unknown. In this randomized pragmatic clinical trial with one-year follow-up, 157 U.S. military personnel and veterans were randomly assigned to receive CRP or self-guided safety planning (SP) prior to beginning massed cognitive processing therapy (CPT) for PTSD. Among 51 (32.5 % of sample) participants endorsing suicidal ideation at baseline, reductions in the severity of suicidal ideation were significantly larger and faster in CRP (F(11,672)= 15.8, p < .001). Among 106 participants denying suicidal ideation at baseline, 8.5 % of CRP participants versus 11.9 % of SP participants (OR=0.69, 95 % CI=0.19-2.52) reported new-onset suicidal ideation during any follow-up assessment. PTSD symptoms significantly reduced over time with no differences between groups. Results support the effectiveness of CRP for rapidly reducing suicidal ideation and managing suicide risk during outpatient treatment for PTSD.

Uncovering the role of substance use in suicide attempts using a mixed-methods approach

INTRODUCTION

Substance use is an established risk factor for suicide attempt. Clarifying the role of substance use in suicide attempts may identify modifiable treatment targets. This study used mixed methods to associate substance use with suicide attempt history and identify pathways through which substance use contributes to attempts.

METHODS

Study 1 included 213 adult inpatients (n = 127 with substance use disorder [SUD]), who completed assessments of suicide attempt history as well as demographic and clinical suicide risk factors. Study 2 was a narrative analysis of suicide attempt stories described by 20 inpatients diagnosed with SUD.

RESULTS

In Study 1, patients with co-occurring alcohol and drug use disorders reported more actual lifetime suicide attempts than did those without SUD. In addition, alcohol and drug use disorders were independently associated with lifetime suicide attempts after controlling for demographic and clinical confounders. In Study 2, substance use played a role in all suicide attempts through at least one pathway before, during, or after a triggering stressor, or as suicide attempt method.

CONCLUSIONS

Substances play a role in suicide attempt baseline risk, acute risk and as means. It is important to target chronic and acute substance use in suicide prevention treatment plans.

Group brief cognitive behavioral therapy for suicide prevention compared to dialectal behavior therapy skills group for military service members: a study protocol of a randomized controlled trial

BACKGROUND

Suicide is a pressing matter for the military. Not only does it pose a health risk, but suicide also compromises operational readiness. Despite provision of suicide prevention clinical best practices, the Department of Defense suffers several challenges (e.g., clinician shortages) limiting the agency's ability to effectively respond to service member suicide. Implementation of evidence-based suicide-specific group therapy is a possible solution to service member well-being needs and system challenges. Service members can also gain coping skills useful beyond managing suicidal thoughts and behaviors.

METHODS

This 2-arm non-inferiority randomized controlled trial compares a group therapy format of Brief Cognitive Behavioral Therapy (i.e., G-BCBT) with Dialectical Behavior Therapy (DBT) Skills Group. Both therapies are delivered in-person at a United States Naval Medical Center. Participants (N = 136) are active-duty service members with recent suicidal thoughts or suicidal behavior. Evaluation features electronically delivered questionnaires at baseline, after each treatment session, and at 3- and 6-month follow-up.

DISCUSSION

The primary outcome concerns G-BCBT impacts on suicidal ideation. Secondary outcomes of interest are suicide attempt, psychological distress (e.g., symptoms of depression, anxiety), and self-regulatory skills (e.g., emotion regulation). We also examine self-regulatory skills as treatment moderators. Clinical trial strengths and limitations are reviewed.

TRIAL REGISTRATION

This study was registered at Clinicaltrials.gov (protocol NCT05401838).

Cognitive behavioral therapy for suicide prevention among Veterans receiving substance use disorder treatment: Results from a randomized trial

Veterans receiving substance use disorder (SUD) treatment are at a clear elevated risk for engaging in suicidal behaviors. Intervening to reduce suicide risk during an episode of SUD treatment could meaningfully target a key high-risk group of Veterans. Cognitive Behavioral Therapy for Suicide Prevention (CBT-SP) was developed to reduce the frequency and duration of suicidal ideation, as well as decrease suicidal behaviors. The form of CBT-SP in this study progressed from building an understanding of the cognitive model to practicing new skills, and highlighted the links between substance use, craving, self-efficacy and suicidal ideation and attempts. CBT-SP was compared to an attention matched 8-session control condition (termed Supportive Psychoeducational Control [SPC]) during a multi-site randomized controlled trial for 299 Veterans receiving outpatient SUD treatment services within the Veterans Health Administration. The frequency of suicidal ideation remained relatively constant over 24-months of follow-up, however the duration of suicidal ideation decreased, and suicide attempts decreased relative to baseline in both conditions. Forty-two participants (14%) reported at least one suicide attempt during the 2-year follow-up period. No statistically significant differences were found between CBT-SP and SPC on any of these outcomes. Analyses of secondary outcomes indicate that preparatory behaviors for suicide were less common among those in the CBT-SP condition than SPC across the 24-month follow-up (OR, 95%CI = 0.44 (0.25, 0.79); p = 0.02). Veterans in SUD treatment are a high-risk group and delivery of suicide-specific interventions is feasible during SUD care. However, results did not indicate that CBT-SP was superior to SPC on any primary outcomes, underscoring the importance of identifying and testing alternative approaches that support suicide reduction in this group.

Cognitive behavioral therapy following esketamine for major depression and suicidal ideation for relapse prevention: The CBT-ENDURE randomized clinical trial study protocol

In 2020, esketamine received a supplemental indication as a therapy for major depression with suicidal ideation (MDSI), based on protocols enrolling hospitalized patients. Given the high risk of suicide following hospital discharge and the high relapse rates following discontinuation of esketamine, the optimal long-term treatment approach remains unclear. Cognitive behavioral therapy (CBT) is highly effective in relapse prevention and has been shown to prevent suicide attempts in high-risk populations. Here we describe the study protocol for the CBT-ENDURE trial: Cognitive Behavioral Therapy Following Esketamine for Major Depression and SUicidal Ideation for RElapse Prevention. Patients with depression (N = 100) who are admitted to hospital or are outpatients with clinically significant suicidal ideation will be enrolled in the study. All patients will receive esketamine (twice weekly for four weeks) and will be randomly assigned (1:1 ratio) to receive a 16-week course of CBT plus treatment as usual (CBT group) or treatment as usual only (TAU only group). Patients are followed for a total of 6 months. Supported under a funding announcement from NIMH to conduct safety and feasibility trials for patients at high risk for suicide, the primary outcome of the CBT-ENDURE study is feasibility (as measured by recruitment and retention), with a key secondary outcome being relapse among those who experience substantial benefit following two weeks of esketamine.

The Design and Application of a Health Behavioral Change (HBC) Roadmap

INTRODUCTION

To assist in addressing medical readiness challenges, the DOD has established various Centers of Excellence to focus efforts to protect, treat, train, and educate service members concerning risks and potential injuries. Using the hearing health domain as a pilot, this effort used DOD methods to evaluate all facets of successful health behavior change (HBC) practices within a military environment and developed a framework and pathway for HBC.

METHODS

The DOD uses the Joint Capabilities Integration and Development System (JCIDS) to ensure new DOD capabilities are identified and fielded in a manner that is interoperable, resilient, and supportables. The study sponsor for the Health Behavioral Change Framework study is the Defense Health Agency Deputy Assistant Director for Research and Engineering (R&E). The main objective of this group was to ensure that final products would both meet the requirements as defined by the JCIDS process, as well as be used by the operational force in addressing HBCs that improve readiness of the joint force.

RESULTS

The Health Behavior Change Guidebook applies to all organizations across the DOD and military health system that may participate in or support specific tasks related to the design, conduct, and assessment of the HBC campaign. The advantage of the process is the ability to define gaps and solutions at an enterprise level. The HBC framework can be applied to a variety of health domains to include behavioral health.

CONCLUSIONS

Use of the "Guidebook for Design, Conduct and Assessment of Health Behavior Change Campaign Within the DOD" and DOTMLPF-P analysis will move Defense Health Agency toward more disciplined use of the JCIDS. The HBC framework allowed the Hearing Center of Excellence to lead the hearing health community to create a capability-based assessment for hearing HBC.

Blending Video Therapy and Digital Self-Help for Individuals With Suicidal Ideation: Intervention Design and a Qualitative Study Within the Development Process

BACKGROUND

Digital formats have the potential to enhance accessibility to care for individuals with suicidal ideation. However, digital self-help interventions have faced limitations, including small effect sizes in reducing suicidal ideation, low adherence, and safety concerns.

OBJECTIVE

Therefore, we aimed to develop a remote blended cognitive behavioral therapy intervention that specifically targets suicidal ideation by blending video therapy with web-based self-help modules. The objective of this paper is to describe the collaborative development process and the resulting intervention and treatment rationale.

METHODS

First, we compiled intervention components from established treatment manuals designed for people with suicidal ideation or behavior, resulting in the development of 11 drafts of web-based modules. Second, we conducted a qualitative study, involving 5 licensed psychotherapists and 3 lay counselors specialized in individuals with suicidal ideation who reviewed these module drafts. Data were collected using the think-aloud method and semistructured interviews, and a qualitative content analysis was performed. The 4 a priori main categories of interest were blended care for individuals with suicidal ideation, contents of web-based modules, usability of modules, and layout. Subcategories emerged inductively from the interview transcripts. Finally, informed by previous treatment manuals and qualitative findings, we developed the remote blended treatment program.

RESULTS

The participants suggested that therapists should thoroughly prepare the web-based therapy with patients to tailor the therapy to each individual's needs. Participants emphasized that the web-based modules should explain concepts in a simple manner, convey empathy and validation, and include reminders for the safety plan. In addition, participants highlighted the need for a simple navigation and layout. Taking these recommendations into account, we developed a fully remote blended cognitive behavioral therapy intervention comprising 12 video therapy sessions and up to 31 web-based modules. The treatment involves collaboratively developing a personalized treatment plan to address individual suicidal drivers.

CONCLUSIONS

This remote treatment takes advantage of the high accessibility of digital formats while incorporating full sessions with a therapist. In a subsequent pilot trial, we will seek input from individuals with lived experience and therapists to test the feasibility of the treatment.

Self-Directed Violence Surveillance in the Veterans Health Administration: A National Examination of Factors Associated with Undetermined Versus Suicide Attempt Classification

This national, observational study examined factors associated with undetermined self-directed violence (SDV) classification among Veterans with a SDV event classified as either "suicide attempt" or "undetermined SDV" in in the Veterans Health Administration (VHA) between 2013 and 2018 (N = 55,878). Generalized estimating equations were used to examine associations of patient and SDV event factors with likelihood of an undetermined SDV classification. Veterans who used poisoning or other methods had 1.52 (95%CI: 1.38, 1.66) and 2.33 (95%CI: 2.16, 2.50) increased odds of having their SDV classified as undetermined, respectively. Veterans with a prior year substance use disorder diagnosis had 1.19 (95%CI: 1.14, 1.24) increased odds of having their SDV classified as undetermined. In sex-stratified analyses, associations of poisoning and substance use disorders held only among males. Additional clinical evaluation of patients with histories of substance use disorders or who use poisoning as method of SDV may be warranted when making SDV determinations.

Designing Clinical Trials to Assess the Impact of Pharmacological Treatment for Suicidal Ideation/Behavior: Issues and Potential Solutions

Suicide is a serious and growing public health concern yet randomized controlled trials (RCTs) that inform pharmacologic treatment remain limited. We emphasize the overall need for such trials and review the literature to highlight examples of trials that have aimed to study patients at elevated risk of suicide. We discuss key examples of existing psychotropic medication trials as well as psychotherapy intervention studies that can yield important design insights. Medications that have been studied in individuals at risk for suicide include lithium, clozapine, zolpidem, prazosin, ketamine, esketamine, and aripiprazole. While important design challenges should be considered-RCTs to study suicide are feasible and much needed. Issues such as overall trial design, patient-selection criteria, and the scales/tools used to assess suicidality are discussed.

Brief and Ultra-Brief Suicide-Specific Interventions

The rising rates of suicide warrant effective treatments that can quickly help stabilize suicidal individuals and prevent future suicidal crises from occurring. Across the past few decades, there has been a rise in the development of ultra-brief (1-4 sessions) and brief suicide-specific interventions (6-12 sessions) to meet this need. This article reviews several prominent ultra-brief and brief interventions, including the Teachable Moment Brief Intervention, Attempted Suicide Short Intervention Program, Safety Planning Intervention, Crisis Response Planning, Cognitive Therapy for Suicide Prevention, Brief Cognitive-Behavioral Therapy for Suicide Prevention, Collaborative Assessment and Management of Suicidality, and the Coping Long-Term With Active Suicide Program. A brief review of each interventions' evidence base is also provided. Current challenges and directions for future research in testing the efficacy and effectiveness of suicide prevention initiatives are discussed.

Improving Suicide Prevention Through Evidence-Based Strategies: A Systematic Review

Objective

The authors sought to identify scalable evidence-based suicide prevention strategies.

Methods

A search of PubMed and Google Scholar identi- fied 20,234 articles published between September 2005 and December 2019, of which 97 were randomized controlled trials with suicidal behavior or ideation as primary outcomes or epidemiological studies of limiting access to lethal means, using educational approaches, and the impact of antidepressant treatment.

Results

Training primary care physicians in depression rec- ognition and treatment prevents suicide. Educating youths on depression and suicidal behavior, as well as active out- reach to psychiatric patients after discharge or a suicidal crisis, prevents suicidal behavior. Meta-analyses find that antidepressants prevent suicide attempts, but individual randomized controlled trials appear to be underpowered. Ketamine reduces suicidal ideation in hours but is untested for suicidal behavior prevention. Cognitive-behavioral therapy and dialectical behavior therapy prevent suicidal behavior. Active screening for suicidal ideation or behavior is not proven to be better than just screening for depression. Education of gatekeepers about youth suicidal behavior lacks effectiveness. No randomized trials have been reported for gatekeeper training for prevention of adult suicidal behavior. Algorithm-driven electronic health record screening, Internet-based screening, and smartphone passive monitoring to identify high-risk patients are under-studied. Means restriction, including of firearms, prevents suicide but is sporadically employed in the United States, even though firearms are used in half of all U.S. suicides.

Conclusions

Training general practitioners warrants wider implementation and testing in other nonpsychiatrist physi- cian settings. Active follow-up of patients after discharge or a suicide-related crisis should be routine, and restricting firearm access by at-risk individuals warrants wider use. Combination approaches in health care systems show promise in reducing suicide in several countries, but evaluating the benefit attributable to each component is essential. Further suicide rate reduction requires evaluating newer approaches, such as electronic health record-derived algorithms, Internet-based screening methods, ketamine's potential benefit for preventing attempts, and passive monitoring of acute suicide risk change.Reprinted from Am J Psychiatry 2021; 178:611-624, with permission from American Psychiatric Association Publishing.

How to save a life: From neurobiological underpinnings to psychopharmacotherapies in the prevention of suicide

The impact of suicide on our societies, mental healthcare, and public health is beyond questionable. Every year approximately 700 000 lives are lost due to suicide around the world (WHO, 2021); more people die by suicide than by homicide and war. Although suicide is a key issue and reducing suicide mortality is a global imperative, suicide is a highly complex biopsychosocial phenomenon, and in spite of several suicidal models developed in recent years and a high number of suicide risk factors identified, we still have neither a sufficient understanding of underpinnings of suicide nor adequate management strategies to reduce its prevalence. The present paper first overviews the background of suicidal behavior including its epidemiology, prevalence, age and gender correlations and its association with neuropsychiatric disorders as well as its clinical assessment. Then we give an overview of the etiological background, including its biopsychosocial contexts, genetics and neurobiology. Based on the above, we then provide a critical overview of the currently available intervention options to manage and reduce risk of suicide, including psychotherapeutic modalities, traditional medication classes also providing an up-to-date overview on the antisuicidal effects of lithium, as well as novel molecules such as esketamine and emerging medications and further molecules in development. Finally we give a critical overview on our current knowledge on using neuromodulatory and biological therapies, such as ECT, rTMS, tDCS and other options.

The Collaborative Assessment and Management of Suicidality compared to enhanced treatment as usual for inpatients who are suicidal: A randomized controlled trial

Background

Although use of inpatient crisis hospital intervention for suicide risk is common, the evidence for inpatient treatments that reduce suicidal thoughts and behaviors is remarkably limited. To address this need, this novel feasibility pilot randomized controlled trial compared the use of the Collaborative Assessment and Management of Suicidality (CAMS) to enhanced treatment as usual (E-TAU) within a standard acute inpatient mental health care setting.

Objectives

We hypothesized that CAMS would be more effective than E-TAU in reducing suicidal thoughts and behaviors. As secondary outcomes we also investigated depressive symptoms, general symptom burden, reasons for living, and quality of the therapeutic relationship.

Methods

All patients were admitted due to acute suicidal thoughts or behaviors. They were randomly assigned to CAMS (n = 43) or E-TAU (n = 45) and assessed at four time points (admission, discharge, 1 month and 5 months after discharge). We used mixed-effects models, effect sizes, and reliable change analyses to compare improvements across and between treatment groups over time.

Results

Intent-to-treat analyses of 88 participants [mean age 32.1, SD = 13.5; n = 47 (53%) females] showed that both groups improved over time across all outcome measures with no significant between-group differences in terms of change in suicidal ideation, depression, reasons for living, and distress. However, CAMS showed larger effect sizes across all measures; for treatment completers CAMS patients showed significant improvement in suicidal ideation (p = 0.01) in comparison to control patients. CAMS patients rated the therapeutic relationship significantly better (p = 0.02) than E-TAU patients and were less likely to attempt suicide within 4 weeks after discharge (p = 0.05).

Conclusions

CAMS and E-TAU were both effective in reducing suicidal thoughts and symptom distress. Within this feasibility RCT the pattern of results was generally supportive of CAMS suggesting that inpatient use of CAMS is both feasible and promising. However, our preliminary results need further replication within well-powered multi-site randomized controlled trials.

Trial registration

DRKS-ID/ICTRP-ID: DRKS00013727. The trial was retrospectively registered in the German Clinical Trials Register, registration code/ DRKS-ID: DRKS00013727 on 12.01.2018 and also in the International Clinical Trials Registry Platform of the World Health Organization (identical registration code).

Overall goal of Cognitive-Behavioral Therapy in Major Psychiatric Disorders and Suicidality: A Narrative Review

Cognitive-behavioral therapy (CBT) is a form of psychological treatment that is based on the underlying assumption that mental disorders and psychological distress are maintained by cognitive factors, that is, that general beliefs about the world, the self, and the future contribute to the maintenance of emotional distress and behavioral problems. The overall goal of CBT is to replace dysfunctional constructs with more flexible and adaptive cognitions. The most relevant cognitive-behavioral techniques in clinical practice are: i. Cognitive Restructuring (also known as the ABCDE method) is indicated to support patients dealing with negative beliefs or thoughts. The different steps in the cognitive restructuring process are summarized by the letters in the ABCDE acronym that describe the different stages of this coaching model: Activating event or situation associated with the negative thoughts, Beliefs and belief structures held by the individual that explain how they perceive the world which can facilitate negative thoughts, Consequences or feelings related to the activating event, Disputation of beliefs to allow individuals to challenge their belief system, and Effective new approach or effort to deal with the problem by facilitating individuals to replace unhelpful beliefs with more helpful ones. ii. Problem-Solving (also known as SOLVE) to raise awareness for specific triggers, and evaluate and choose more effective options. Each letter of the SOLVE acronym identifies different steps of the problem-solving process: Select a problem, generate Options, rate the Likely outcome of each option, choose the Very best option, and Evaluate how well each option worked. For example, a suicide attempt is reconceptualized as a failure in problem-solving. This treatment approach attempts to provide patients with a better sense of control over future emerging problems. iii. Re-attribution is a technique that enables patients to replace negative self-statements (eg, "it is all my fault") with different statements where responsibility is attributed more appropriately. Furthermore, decatastrophizing may help subjects, especially adolescents decide whether they may be overestimating the catastrophic nature of the precipitating event, and by allowing them to scale the event severity they learn to evaluate situations along a continuum rather than seeing them in black and white. iv. Affect Regulation techniques are often used with suicidal adolescents to teach them how to recognize stimuli that provoke negative emotions and how to mitigate the resulting emotional arousal through self-talk and relaxation.

Suicide Attempt Aftercare in Geriatric Patients: A Pilot Project

Hospitalized patients after suicide attempts gave informed consent to a postvention project after discharge. A continuous caregiver contacted the subjects monthly by phone for a period of 1 year. In case of significant worsening and reoccurrence of suicidal ideations, immediate re-admission was possible. Ten subjects 65 years and older and hospitalized because of suicide attempts were included. The sample was presumed to be at high risk for repeated suicides because of somatic comorbidities and social isolation. Affective state was monitored using the PHQ-9. At the end, the social situation was assessed using the MILVA inventory. Of 16 patients screened for participation only 10 gave informed consent. Six subjects completed the study per protocol. Three subjects died (one suicide, two deaths by natural causes) and one dropped out for other reasons. At the end of the study, all completers appreciated the continuous guidance. While the affective state remained relatively stable in most subjects during the observed period, activities and social isolation could not be modified. Only one patient was readmitted during the project. Phone contacts proved to be feasible in the follow-up after suicide attempts especially in old age, because of the limited mobility of this vulnerable population.

Burnout, Surface Acting, and Suicidal Ideation Among Military Personnel: Results of a Longitudinal Cohort Study

Introduction: Chronic life stressors are positively correlated with suicidal ideation and suicidal behaviors among military personnel. Surface acting, a strategy that involves hiding or faking one's emotional state to match organizational expectations dictating when and how to express emotions, contributes to burnout and increased emotional distress. Because surface acting involves a form of emotional suppression, frequent use of surface acting may also contribute to suicidal ideation. Methods: One thousand seven-hundred fifty-four military personnel stationed at a U.S. military installation completed a self-report survey repeatedly administered 6 times from January 2020 to December 2021. Survey items assessed suicidal ideation, surface acting, burnout, and depression. Results: Burnout and surface acting were significantly correlated with severity of suicidal ideation. When depression was added as a covariate, surface acting but not burnout remained a statistically significant correlate of suicidal ideation. Discussion: Surface acting, a job-specific form of emotional suppression, may increase suicide risk among military personnel. Creating opportunities for military personnel to appropriately express their emotional states could mitigate suicide risk in this population.

Encouraging the use of the Veterans Crisis Line among high-risk Veterans: A randomized trial of a Crisis Line Facilitation intervention

The Veterans Crisis Line (VCL) is a core component of VA's suicide prevention strategy. Despite the availability and utility of the VCL, many Veterans do not utilize this resource during times of crisis. A brief, psychoeducational behavioral intervention (termed Crisis Line Facilitation [CLF]) was developed to increase utilization of the VCL and reduce suicidal behaviors in high-risk Veterans. The therapist-led session includes educational information regarding the VCL, as well as a chance to discuss the participant's perceptions of contacting the VCL during periods of crisis. The final component of the session is a practice call placed to the VCL by both the therapist and the participant. The CLF intervention was compared to Enhanced Usual Care (EUC) during a multi-site randomized clinical trial for 307 Veteran participants recently hospitalized for a suicidal crisis who reported no contact with the VCL in the prior 12 months. Initial analyses indicated that participants randomized to the CLF intervention were less likely to report suicidal behaviors, including suicide attempts compared to participants randomized to receive EUC over 12-months of follow-up (χ² = 18.48/p < 0.0001), however this effect was not sustained when analyses were conducted on an individual level. No significant differences were found between conditions on VCL utilization. Initial evidence suggests a brief CLF intervention has an impact on preventing suicidal behaviors in Veterans treated in inpatient mental health programs; however, it may not change use of the VCL. This brief intervention could be easily adapted into clinical settings to be delivered by standard clinical staff.

Scores on the suicide cognitions scale-revised (SCS-R) predict future suicide attempts among primary care patients denying suicide ideation and prior attempts

BACKGROUND

Approximately half of patients who attempt or die by suicide screened negative for suicidal ideation during their most recent medical visit. Maladaptive beliefs and schemas can increase cognitive vulnerability to suicidal behavior, even among patients without recent or past suicidal thoughts and behaviors. Assessing these beliefs could improve the detection of patients who will engage in suicidal behavior after screening negative for elevated suicide risk.

METHODS

Primary care patients who completed the Patient Health Questionnaire-9 and the Suicide Cognitions Scale-Revised (SCS-R) during routine clinic visits and denied suicidal ideation at baseline (N = 2417) were included in the study sample. Suicidal behaviors during the 12 months after baseline were assessed. Logistic regression analyses examined the association of baseline SCS-R scores with later suicidal behavior.

RESULTS

In both univariate and multivariate analyses, SCS-R total scores were associated with significantly increased risk of suicidal behavior within 90, 180, and 365 days post-baseline. Results were unchanged when patients who reported prior suicidal behavior were excluded (N = 2178). In item-level analyses, all 16 SCS-R items significantly differentiated patients with and without follow-up suicidal behavior.

LIMITATIONS

Study limitations included missing follow-up data, restriction of sample to U.S. military medical beneficiaries, and inability to assess representativeness of the sample relative to the full primary care population.

CONCLUSIONS

SCS-R scores are elevated among patients who attempt suicide after denying both suicidal ideation and prior suicide attempts, suggesting the scale may reflect enduring suicide risk. The SCS-R could enhance suicide risk screening and assessment.

Interventions for attempted suicide

PURPOSE OF REVIEW

Suicide is a major, global, public health issue. Those who attempt suicide represent a high-risk subgroup for eventual death by suicide. We provide an update on emerging evidence for interventions for attempted suicide to reduce subsequent suicidal behavior.

RECENT FINDINGS

Major approaches that have been examined recently include pharmacological, psychosocial, brief active contact and outreach interventions, and digitally driven interventions. Notwithstanding the limited evidence base for most of these approaches, brief contact and follow-up interventions appear to have more robust effects on reduction of repeat suicidal behavior, including attempts; such approaches may have especial significance in emergency settings because of their brevity. Digital interventions for self-harm appear promising in the short-term whereas the evidence for pharmacological and psychosocial strategies remain inconclusive.

SUMMARY

Although current evidence supports the use of brief interventions, contact, and outreach for reducing risk of subsequent suicide attempts and suicidal behavior, there are large gaps and limitations in the evidence base related to trial design, lack of long-term efficacy data, and implementational challenges. More robustly designed long-term trials that examine integrated intervention approaches with well defined outcomes are needed to develop recommendations in this area.

Relapse Prevention Intervention after Suicidal Event (RISE): Feasibility study of a psychotherapeutic short-term program for inpatients after a recent suicide attempt

Recent research suggests that treating only mental disorders may not be sufficient to reduce the risk for future suicidal behavior in patients with a suicide attempt(s). It is therefore necessary to pay special therapeutic attention to past suicidal acts. Thus, the newly developed RISE (Relapse Prevention Intervention after Suicidal Event) program was built on the most effective components of existing psychotherapeutic and psychosocial interventions according to our current meta-analysis. The RISE program consists of five individual sessions designed for the acute psychiatric inpatient setting. The main goals of the treatment are to decrease future suicidal events and to improve patients' ability to cope with future suicidal crises. In the present study, feasibility and acceptance of the RISE program were investigated as well as its clinical effects on suicidal ideations, mental pain, self-efficacy and depressive symptoms. We recruited a sample of 27 inpatients of the Department of Psychiatry and Psychotherapy, University Hospital Jena, Germany. The final sample consisted of 20 patients hospitalized for a recent suicide attempt, including 60 percent of multiple attempters. The data collection included a structured interview and a comprehensive battery of questionnaires to evaluate the feasibility and acceptance of the RISE program as well as associated changes in clinical symptoms. A follow-up examination was carried out after 6 months. Considering the low dropout rate and the overall positive evaluation, the RISE program was highly accepted in a sample of severely impaired patients. The present study also demonstrated that the levels of suicidal ideations, mental pain, depressive symptoms, and hopelessness decreased significantly after RISE. Since all of these clinical parameters are associated with the risk of future suicidal behavior, a potential suicide-preventive effect of the intervention can be inferred from the present findings. The positive results of the follow-up assessment after 6 months point in the same direction. In addition, RISE treatment increased self-efficacy in patients, which is an important contributor for better coping with future suicidal crises.

A Standard Protocol for the Clinical Management of Suicidal Thoughts and Behavior: Implications for the Suicide Prevention Narrative

The last several decades have witnessed growing and converging evidence from randomized controlled trials (RCT's) that an identifiable set of simple clinical management strategies are effective for those at risk for suicidal thinking and/or suicide attempts. The current article offers a brief review of clinical strategies supported by RCT's targeting suicidality as "commonalities of treatments that work" and related recommendations for use in the delivery of care for suicidal individuals in generic fashion, regardless of any particular treatment, theoretical orientation, or intervention perspective. The article includes eight recommendations that can be easily adapted across the full range of clinical contexts, institutional settings, and delivery systems, recommendations that help frame a broader clinical narrative for suicide prevention. Recommendations cut across five identifiable domains or clinical strategies for the delivery of care: (1) informed consent discussion that identifies risks of opting out of care and emphasizes the importance of shared responsibility and a collaborative process, (2) an explanatory model that emphasizes the importance of individual self-management skills and targeting the causes of suicide rather than describing suicidality as a function of mental illness, (3) the importance of proactively identifying barriers to care and engaging in targeted problem-solving to facilitate treatment adherence, (4) a proactive and specific plan for management of future suicidal episodes, and (5) reinforcing the importance of taking steps to safeguard lethal means and facilitate safe storage of firearms.
