   School shootings and mental health outcomes: a scoping review.

   Injury prevention : journal of the International Society for Child and Adolescent Injury Prevention (Rencken et al.)Published May 15, 2026Checked Oct 16, 2026

   “Inclusion criteria encompassed all publication dates, study designs and populations affected. Key attributes were extracted and analysed from included studies.ResultsOf 2798 studies identified, 84 met inclusion criteria, with 13% being qualitative. Despite covering 19 unique shootings, 40% of the articles focused on Virginia Tech and Northern Illinois University. Most studies were cross-sectional (42%), and students were the primary population studied (80%). Post-traumatic stress disorder (29%) and depression (11%) were the most commonly studied outcomes. Common predictors included age (13%) and trauma history (12%). Higher exposure levels to school shootings, prior trauma and existing mental health conditions were key predictors of adverse mental health outcomes. Social support from family or peers emerged as protective factors.ConclusionWhile findings of this review suggest that there is a substantial impact of school shootings on survivors' mental health, additional research is needed to encompass impacted communities beyond students, integrate qualitative methods and incorporate longitudinal studies to track mental health outcomes over time.”

   School Shootings and Their Lasting Impact: A Review of the Educational, Mental Health, and Socioeconomic Consequences for U.S. Students

   Open Journal of Social Sciences (Idi & Patrick)Published Jan 1, 2025Checked Oct 16, 2026

   “This review brings together extant literature on the education, psychological, and socioeconomic consequences of school-centered incidents of firearm violence. The evidence suggests that exposure to violence hinders students’ education experience substantially, contributing to higher rates of absenteeism and grade retention and further damaging standardized testing performance, proportions of graduates, and admissions to college. Psychological outcomes are equally pronounced, with elevated risk for post-traumatic stress disorder, depression, anxiety, and increased utilization of mental health services and pharmacotherapy. Extend beyond school contexts, the lasting socioeconomic impact includes diminished employment prospects and widening disparities, especially for populations that are systemically disadvantaged. In aggregate, the results portray school shootings generating lasting ripple effects that disable the development of human capital and inhibit social mobility. The conclusion underscores the importance of unifying trauma-informed education and health strategies and sweeping policy intervention toward the root causes of handgun violence.”

   Silent echoes: understanding and predicting the widespread mental health impact of mass shootings.

   Frontiers in public health (Mishra & Coleman)Published Aug 26, 2026Checked Oct 16, 2026

   “We find that mass shootings are associated with increased anxiety and depression after controlling for demographic and socioeconomic variables. Translating effect sizes to counts yields an estimated ~2.27 million additional adults screening positive for anxiety and ~1.29 million additional adults for depression nationwide after a public mass shooting. Moreover, our analyses indicate that higher death counts and younger victims are associated with increased nationwide effects. Analysis of data from survey waves immediately before and after the 2022 Robb Elementary School shooting finds that anxiety and depression increased and that the size of the effect was inversely proportional to geographic distance from the shooting. Therefore, our results indicate that the mental-health costs of mass shootings are widespread, and it is critical to offer public-health responses that extend beyond the immediate communities where mass shootings occur.”

   Prevalence and Timing of Suicidal Ideation, Preparation, and Attempts Among Mass Shooting Survivors.

   Suicide & life-threatening behavior (Schildkraut et al.)Published Jun 1, 2026Checked Oct 16, 2026

   “This study examines the prevalence and timing of suicidal ideation, preparation, and suicide attempts, as well as variation across subgroups.MethodsData were drawn from a survey of 167 individuals directly and indirectly exposed to mass public shootings in the United States. Suicidal ideation, preparation, and suicide attempts were assessed using items from the Self-Injurious Thoughts and Behaviors Interview. Descriptive analyses examined prevalence, timing, and subgroup variation.ResultsHalf of respondents reported suicidal ideation (50.9%), while 16.8% reported preparation and 7.8% reported suicide attempts. The more common time frame for all three outcomes was more than 1 year prior, although some respondents reported recent experiences. Variation across exposure and victimization groups was observed descriptively, while differences by race/ethnicity were limited.ConclusionsSuicidal thoughts and behaviors are present among a substantial proportion of mass shooting survivors, with respondents reporting experiences across multiple timeframes. Findings highlight the importance of ongoing identification and intervention efforts.”

   Trauma at School: The Impacts of Shootings on Students' Human Capital and Economic Outcomes

   National Bureau of Economic Research (Cabral et al.)Published Dec 1, 2020Checked Oct 16, 2026

   “We examine how shootings at schools-an increasingly common form of gun violence in the United States-impact the educational and economic trajectories of students.Using linked schooling and labor market data in Texas from 1992 to 2018, we compare within-student and across-cohort changes in outcomes following a shooting to those experienced by students at matched control schools.We find that school shootings increase absenteeism and grade repetition; reduce high school graduation, college enrollment, and college completion; and reduce employment and earnings at ages 24-26.We further find school-level increases in the number of leadership staff and reductions in retention among teachers and teaching support staff in the years following a shooting.The adverse impacts of shootings span student characteristics, suggesting that the economic costs of school shootings are universal.”

   Survivor perspectives on research priorities for assessing mental health outcomes after school shootings: a qualitative study

   Injury Epidemiology (Rencken et al.)Published Mar 12, 2025Checked Oct 16, 2026

   “The study identified three key research priorities: (1) understanding the long-term mental health impacts of school shootings across the life course, (2) expanding research to include broader outcomes beyond traditional mental health metrics, and (3) diversifying research approaches, study designs, and study populations to better capture the varied experiences of survivors. There is a need for researchers to explore a wider range of outcomes, communities, and timeframes when studying the mental health impacts of school shootings. Such investigations are essential for understanding the complex and unique aspects of recovery and resilience among survivors.”

   Posttraumatic stress among students after the shootings at Virginia Tech.

   Psychological Trauma Theory Research Practice and Policy (Hughes et al.)Published Jul 18, 2011Checked Oct 16, 2026

   “Exposure to trauma-related stressors varied greatly, from 64.5% unable to confirm the safety of friends to 9.1% who had a close friend killed. Odds ratios for stressors predicting high levels of posttraumatic stress symptoms were highest for losses (2.6–3.6; injury/death of someone close) and inability to confirm the safety of friends (2.5). Stressor effects were unrelated to age, gender, and race/ethnicity. The exposures that explained most of the cases of high posttraumatic stress symptoms were inability to confirm the safety of friends (30.7%); death of a (not close) friend (20.3%); and death of a close friend (10.1%). The importance of high-prevalence low-impact stressors resulted in a low concentration of probable cases of PTSD, making it difficult to target a small, highly exposed segment of students for mental health treatment outreach. The high density of student social networks will likely make this low concentration of probable PTSD a common feature of future college mass trauma incidents, requiring broad-based outreach to find students needing mental health treatment interventions.”
