The Cornell University College of Human Ecology categorizes self-injury as intentional carving or cutting of the skin, subdermal tissue scratching, intentional burning, banging or punching oneself, and embedding objects under the skin. To date, sixteen forms of self-injury have been documented, and recent studies show that there is no one "profile" for self-harm. This critical edition discusses self-mutilation and other self-harm behaviors. Chapters explore why some individuals harm themselves, the risks of self-injury, and how to treat and prevent it.
