Abstract
Post-traumatic stress disorder (PTSD) is significantly associated with an increased risk for suicidal behavior among adolescents. Suicide is one of the top three causes of adolescent deaths worldwide. Despite the strong relationship between PTSD and suicidal behavior, precise causal pathways linking PTSD to suicide in adolescents remains unclear. A slew of mediating factors and variables commonly present themselves with both suicide and PTSD, including co-morbid psychiatric disorders, exposure to different forms of trauma and stressful life events, core neurobiological changes, and mental, emotional, and physiological states such as hyperarousal, impulsivity, and aggression. Because youth is such a critical stage of development, it is very important that at-risk adolescents are identified and referred for treatment. With many treatment challenges in these populations, effective implementation and use of prevention methods are of increasing importance. The most proven prevention methods include physician education, means restriction, and gatekeeper training. Other strategies that have received empirical support are public education campaigns and implementing guidelines for the media, including those for television, print media, and the Internet.
