Risk factors
By Mayo Clinic staffCertain factors may increase the risk of self-injury, including:
- Age. Most people who self-injure are teenagers. Self-injury often starts in the early teen years, when emotions are more volatile and children face increasing peer pressure, loneliness, and conflicts with parents or other authority figures.
- Having friends who self-injure. People who have friends who intentionally harm themselves are more likely to begin self-injuring.
- Life issues. Some people who injure themselves were sexually, physically or emotionally abused as children or adults. They may also have experienced neglect in childhood.
- Mental health issues. Among those at highest risk are people who experience many negative emotions and are highly self-critical. People who self-injure are more likely to be impulsive and to have poor problem-solving skills. In addition, self-injury is commonly associated with certain mental illnesses, including borderline personality disorder, depression, anxiety disorders, substance abuse disorders, post-traumatic stress disorder and eating disorders.
- Alcohol or substance use. People who harm themselves often do so while under the influence of alcohol or illegal drugs.
