Non-suicidal self-injury (NSSI), often called self-harm, describes any intentional behavior that injures oneself without suicidal intent. NSSI commonly manifests as cutting/scratching, burning, hitting oneself, and head banging. Research, such as a 2007 study from Cornell University, indicates that 13.0% to 23.2% of adolescents will engage in NSSI at some point in their lives, with the average age of onset being 12-14. Individuals engage in NSSI primarily to cope with overwhelming emotions, find a sense of grounding, connect with their surroundings, or reduce feelings of dissociation. While a small percentage of individuals may engage in NSSI to seek attention, the vast majority tend to hide their behavior.
