The intentional injury of one's own body, otherwise known as self-injury, is a relatively common phenomenon among adolescents today. Although many students self-injure, physical educators should not consider self-injury a normal developmental experience that does not warrant attention. Rather, physical educators are encouraged to recognize self-injury as a sign of emotional distress and use their role within the school to connect students with appropriate mental-health support services. This article presents a brief overview of self-injury, including demographics, types and functions. In addition, it provides information on how to identify and have conversations with students about self-injury, and make appropriate referrals to the school counselor. It should be clear that the physical educator is not expected to counsel students, but rather, identify the symptoms and take the appropriate steps when self-injury is suspected.
