Other definitions

Strictly speaking, self-harm is a general term for self-damaging activities (which could include such activities as alcohol abuse or bulimia). Self-injury refers more specifically to the practice of cutting, bruising, poisoning, over-dosing (without suicidal intent), burning, or otherwise directly injuring the body.[10] Many people, including health-care workers, define self-harm based around the act of damaging one's own body. It may be more accurate to define self-harm based around the intent, and the emotional distress that the person wishes to deal with. An example of this form of definition is provided by the self-injury awareness charity, LifeSIGNS.[11]
