Sexual harassment is a prevalent yet understudied challenge adolescents face in high school. Because sexual harassment is associated with negative well-being indicators like depression, substance use, and suicidality, school stakeholders must understand its potential consequences for student well-being, and how school climate might impact…

School threat assessment is a violence prevention strategy that has become widely used over the past 20 years; however, the procedures for a threat assessment are not well-known in education and it has received relatively little research attention. This article describes the rationale, procedures, and empirical support for the Comprehensive School…

This research paper presents an operationalization procedure for measuring fidelity of implementation (FOI) of a school-based crisis prevention program. The implementation literature recommends that program developers specify core components of an intervention that are directly related to a program's theory of change and need to be implemented…

Virginia law mandates the use of threat assessment in all public schools, yet there is little research on grade-level differences. This study investigated a statewide sample of 3,282 threats from 1,021 schools. Threats significantly differed across grade level in demographics, characteristics, and outcome. As grade increased, students were more…

National debate over law enforcement in schools has largely overlooked student reporting of violent threats to school resource officer (SROs). This statewide assessment of Virginia high school students (n = 99,358) found that the majority of Black (64%), Hispanic (72%), White (71%), and other racial/ethnic identity (71%) students agreed the SRO…

Threat assessment is a violence prevention strategy used to investigate and respond to threats to harm others. In 2013, Virginia mandated the use of threat assessment teams for threats to self and to others, effectively subsuming suicide assessment with threat assessment and raising questions about the distinction between the two practices. In a…

In 2013, VA became the first state to mandate the use of threat assessment teams in its K-12 public schools. We provide an account of the development and adaptation of threat assessment as a school safety practice and research on the Virginia Student Threat Assessment Guidelines in VA schools. We describe the state law and the question of whether…

School psychologists are frequently called upon to assess students who have made verbal or behavioral threats of violence against others, a practice commonly known as threat assessment. One critical issue is whether the outcomes of a threat assessment generate the kind of racial disparities widely observed in school disciplinary practices. In…

Separate lines of research find that proaggressive attitudes promote peer aggression and that bystanders play a pivotal role in deterring or facilitating bullying behavior. The current study hypothesized that proaggressive attitudes in middle school would deter students from standing up to bullying and encourage them to reinforce bullying…

The standardized, indicated school-based prevention program "Networks Against School Shootings" combines a threat assessment approach with a general model of prevention of emergency situations in schools through early intervention in student psychosocial crises and training teachers to recognize warning signs of targeted school violence.…

In this commentary, Cornell and Bradshaw report decades of research in school psychology have brought attention to the culture of peer bullying and harassment that was a largely neglected problem in most schools. At the same time, research on the school environment has brought recognition to the importance of a safe and supportive school climate.…

This study investigated the relations between student perceptions of support and student willingness to seek help for bullying and threats of violence in a sample of 7318 ninth-grade students from 291 high schools who participated in the Virginia High School Safety Study. Hierarchical linear modeling indicated that students who perceived their…

The study in this article compared counselors and teachers on measures of suicide knowledge and prevention practices after participation in a statewide training program in student suicide prevention using the "Question, Persuade, and Refer" program. Follow-up surveys conducted an average of 4.7 months after training indicated that trainees (73…

Threat assessment has been widely recommended as a violence prevention approach for schools, but there are few reports of its implementation. Memphis City Schools adapted the Virginia threat assessment guidelines (Cornell & Sheras, 2006) for use by a centralized team serving 194 schools and a student population of 118,000. This article…

Threat assessment has been widely recommended as a violence prevention approach for schools, but there are few empirical studies of its use. This nonexperimental study of 280 Virginia public high schools compared 95 high schools using the Virginia threat assessment guidelines (Cornell & Sheras, 2006), 131 following other (i.e., locally…
