[Self-injurious behaviour: phenomenology, risk factors, and course].

Self-injurious behavior refers to the direct destructive treatment of one's own body performed without suicidal intent. Many methods are observable, and different body parts are harmed, particularly arms and legs. The 6-month prevalence of self-injurious behavior is projected at 4% in the general population. Such behavior most often supports emotional regulation. Traumatic experiences, mental disorders, and general impulsivity facilitate its appearance.
