Diagnosis

Self-mutilation can be difficult to diagnose. People who self-mutilate often feel guilty and ashamed about their behavior. They may try to hide it. Physical harm caused by self-mutilation may be the first sign noticed during an exam. To be diagnosed, symptoms should meet the following criteria:
  • Excess thinking about physically harming oneself
  • Inability to resist harming oneself, resulting in tissue damage
  • Increased tension before and a sense of relief after self-injury
  • Having no suicidal intent in the self-mutilation
To make an accurate diagnosis, the psychologist or psychiatrist will assess other conditions, such as personality or mood disorders, and whether there is suicidal intent. A psychosocial assessment may also be given to assess a person’s mental capacity, level of distress, and presence of mental illness.
