Research on firearm purchaser licensing laws has found population level reductions in firearm-related mortality. Limited research has been conducted specifically examining the impact of these laws among adolescents and emerging adults. We obtained death data from the National Center for Health Statistics from 1990 to 2019. We generated state-year…

Scholars theorize that the nature of school gun violence varies across school settings. Yet, there is a lack of statistical research testing this idea. This study investigates contextual factors associated with six forms of school gun incidents (N = 1,238) over a 40-year period (1980-2019) in the United States. To conduct the analyses, school,…

Gun violence is a significant public health issue. The U.S. has more than one mass shooting a day in which four or more people are injured or killed.

The State of Nevada launched the "Nevada SafeVoice" anonymous tip line to prevent harmful events in schools and to promote student safety, health, and wellbeing. We assessed the extent to which "SafeVoice" contributed to reductions in school discipline incidents, youth suicides, and increases in the positive school climate.…

Background: Despite a vast literature linking in-home firearm access to youth suicides, few studies have examined whether and how "gaining" access to household firearms shapes adolescents' development of suicidal ideation. Objective: This study examined whether gaining access to household firearms among U.S. adolescents is associated…

Firearm suicides among adolescents have increased in the US and rates vary across racial and ethnic groups. In this study, we examined contextual information around adolescent firearm suicides and analyzed how incident characteristics vary across racial and ethnic groups. We analyzed firearm suicides among adolescents (ages 10-18 years) from 2004…

These shootings included 473 intentional shootings (encompassing 354 with known offenders and 119 with…

While firearm-related injuries are the leading cause of death among US children between 1-18, and account for nearly half of suicides among young people, public health experts continue to struggle in identifying efficacious mechanisms to reduce and prevent firearm access for children. Currently 4.8 million children live in a home with a loaded and…

Recently, a mnemonic device, SHORES, was created for counselors to utilize with clients with suicidal ideation. The acronym of SHORES stands for Skills and strategies for coping (S); Hope (H); Objections (O); Reasons to live and Restricted means (R); Engaged care (E); and Support (S). In this manuscript, SHORES is introduced as a way for school…

Background: Youth violence reduction is a public health priority, yet few studies have examined secular trends in violence among urban youth, who may be particularly vulnerable to numerous forms of violence. This study examines 10-year secular trends in the prevalence of violence-related behaviors among Philadelphia high school students. Methods:…

That campuses suffer unacceptable levels of violence is undisputable; they are part of a larger American society in which family, community, and institutional violence far exceed levels found in comparable Western nations. And yet, amid the finger-pointing and scapegoating of students as violent, we note a critical lack of evidence-based analysis,…

Background: The United States has more than 90% of all youth firearm deaths that occur in high-income countries. Purpose: We summarize the epidemiological literature on the prevalence, risk factors, and protective factors associated with adolescent homicides and suicides and the role of firearms in the loss of these lives. Methods: A systematic…

This study examined the psychometric properties of the Risk Assessment and Distress Recovery (RADR) Scale--a new self-report psychological screening tool for high school students that explores risk factors related to mental health characteristics of students who have engaged in school violence. The sample consisted of 1093 high school students…
