Violence Prevention: How necessary is it?

Rates of school violence in K-12 schools in the US are startling. A 2014 study found that the number of youth homicide victims could fill 89 school buses annually. And each year, the number of youth hospitalized for assault-related injuries is high enough to fill every seat within 9 football stadiums. These alarming statistics call for better prevention programs to decrease youth violence.violence.jpg

Many schools engage in secondary prevention methods such as metal detectors and police intervention programs. A literature review conducted by Hankin and Hertz (2011), however, concluded there were insufficient data to determine whether metal detectors were effective in reducing violence among adolescents in middle and high schools. And though many states have their own violence prevention programs such as the Gang Resistance Education and Training (G.R.E.A.T.) and Law-Related Education (L.R.E.), other programs such as Botvin LifeSkills Training (LST) have been shown to yield better results.

The CDC recommends evidence-based programs such as LST because of their proven effectiveness in reducing violence and drug use. A 2006 study conducted in New York City  found significant reduction in violence and delinquency amongst students who received LST compared to students who received standard health education provided by New York City public schools. Results from a 3-month follow up indicated that those who received the LST intervention (2,734 students) showed a 25.6% decrease in physical aggression compared to those who did not (2,484 students).

National Health Promotion Associates (NHPA) is currently conducting research on substance and violence prevention by evaluating LST in different cohort settings. One of the most popular and successful project conducted by NHPA is the middle school program that teaches self-management skills, general social skills, and drug resistance skills to 6-9th graders. The program is recognized by organizations such as the National Institute of Health, U.S. Department of Education, the National Registry of Evidence Based Programs and Practice, and many more.
