Objective: To evaluate the effectiveness of the IDF Suicide Prevention Program, implemented since 2006.Design: Quasi-experimental (before and after) cohort study.Participants: Two cohorts of IDF mandatory service soldiers: the first inducted prior to (1992–2005,n= 766,107) and the second subsequent to (2006–2012,n= 405,252) the launching of the intervention program.Exposure: The IDF Suicide Prevention Program is a population-based program, incorporating: reducing weapon availability, de-stigmatizing help-seeking behavior, integrating mental health officers into service units, and training commanders and soldiers to recognize suicide risk factors and warning signs.Main outcome measure: Suicide rate and time to suicide in cohorts before and after exposure to the Suicide Prevention Program.Results: Trend analysis showed lower suicide rates in the cohort after intervention. The hazard ratio for the intervention effect on time to suicide was 0.44 (95% CI = 0.34–0.56,P< .001) among males. Lower risk was associated with: male gender; born in Israel; higher socio-economic status; higher intelligence score; and serving in a combat unit (HR = 0.43: 95% CI = 0.33–0.55).Conclusions: There was a 57% decrease in the suicide rate following the administration of the IDF Suicide Prevention Program. The effect of the intervention appears to be related to use of a weapon, and being able to benefit from improved help-seeking and de-stigmatization. Future efforts should seek to extend the program's prevention reach to other demographic groups of soldiers. The success of the IDF program may inform suicide prevention in other military organizations and in the civilian sector.

Moral injury is increasingly recognized as a significant concern among medical personnel and first responders, particularly in high-stress healthcare and emergency settings. This review aims to synthesize current evidence on the prevalence, risk factors, and outcomes of moral injury among medical personnel and first responders across diverse healthcare and emergency response environments. We included peer-reviewed studies reporting on moral injury among medical personnel or first responders in any healthcare or emergency response setting, excluding studies that did not report original data or focused solely on military populations. We systematically searched PubMed, Google Scholar, and Central, up to April 2025. Risk of bias was assessed directly from the manuscripts. Data were synthesized narratively and, where possible, pooled using random-effects meta-analysis. A total of 41 studies involving 14,500 participants were included. The prevalence of moral injury ranged from 4.1% to 69.44% across settings. Key risk factors identified included exposure to traumatic events, organizational constraints, and lack of support. Meta-analysis indicated a significant association between moral injury and symptoms of PTSD. The evidence is limited by heterogeneity in measurement tools and study designs, as well as a moderate risk of bias in several included studies. In conclusion, moral injury is prevalent among medical personnel and first responders, with important implications for mental health interventions and organizational policy.

Suicide rates within the U.S. military are elevated. The interpersonal theory of suicide, supported within military samples, suggests that social disconnectedness confers risk for suicide. Autism spectrum disorder (ASD) is characterized by symptoms-difficulties in social communication/interaction (SCI) and restricted and repetitive behaviors (RRBs)-that contribute to social disconnectedness. To our knowledge, no study has examined ASD-related traits and suicide risk among active duty U.S. military service members. Participants included 292 active duty U.S. military service members (M [SD] age = 28.67 [7.40] years, 68.5% male, 78.1% White). The Autism Spectrum Quotient, Repetitive Behaviours Questionnaire-2 for Adults, Self-Injurious Thoughts and Behaviors Interview-Short Form, and Interpersonal Needs Questionnaire assessed for SCI difficulties, RRBs, suicidal symptoms, and interpersonal theory of suicide constructs (i.e., perceived burdensomeness, thwarted belongingness), respectively. Elevated levels of SCI difficulties and RRBs were associated with increased odds of reporting suicidal thoughts and behaviors occurring since joining the military, controlling for the number of years of service and suicidal symptoms occurring prior to joining the military. Perceived burdensomeness and thwarted belongingness statistically accounted for the relationship between ASD-related traits and suicidal ideation occurring since joining the military; a rival mediator, emotion dysregulation, was not a significant mediator. Among active duty U.S. military service members, greater ASD-related traits were associated with an increased likelihood of reporting suicidal thoughts and behaviors occurring since joining the military. Clinical efforts targeting perceived burdensomeness and thwarted belongingness might reduce suicide risk among military service members with elevated ASD-related traits.

There is an ongoing debate on the effectiveness of suicidal behavior prevention measures in the military. The association of three widely used tools with severe suicide attempts was assessed in this setting. Thirty-nine Israeli soldiers (59% males), mean age 19 yrs., who attempted suicide during military service were divided into two groups: severe (n = 14; 35.9%) and moderate suicide attempts, and were assessed using the Scale for Suicide Ideation (SSI), Suicide Intent Scale (SIS) and the Columbia Suicide Severity Rating Scale (C-SSRS). Seven items from the SSI (p = 0.008), two items from SIS and one item from C-SSRS were associated with severe suicide attempts. Kendall's tau-b correlation with bootstrap demonstrated stability of these correlations. Greater severity of suicidal ideation was associated with more severe suicide attempts. The combination of male gender, available firearms and current severe suicide ideation is high-risk danger sign in a military setting, even when reported intent to die is low.
