Approximately 14 to 17 percent of adolescents today self-harm, deliberately cutting, burning, or bruising themselves. Most self-harming adolescents use the behavior as a coping strategy to get immediate relief from emotional distress or other stressors in their lives. Stressors include fitting in with peers, activity and homework overload, fears about the future, and emotional disconnection in families. Schools can provide two major high school interventions that can help reduce the likelihood that self-harming epidemics will occur: (1) Schools can initiate on-site education programs that provide guidance and support for self-harming students; and (2) they can educate responding adults about self-harming so they understand the common causes, signs, and symptoms of the behavior, know how to differentiate self-harming behavior from suicidal behavior, are aware of effective treatments, and know how to respond in constructive and empowering ways.
