Tests and diagnosis

By Mayo Clinic staff

Unless you're ready to stop self-injuring and you tell someone about your behavior, it can be difficult for a doctor or therapist to diagnose self-injury. Sometimes self-injury is discovered accidentally. For instance, a doctor doing a routine medical examination may notice signs, such as scars or fresh injuries.

In any case, there's no specific diagnostic test for self-injury. Diagnosis is based on a physical and mental evaluation. During an initial evaluation for self-injury, a health care provider may ask you such questions as:

  • When your self-injury began
  • How often you cut or injure yourself in other ways
  • What types of self-injury you use
  • What seems to trigger your self-injury
  • What emotional issues you face
  • What social networks or relationships you have
  • What previous treatment, if any, you've had
  • Your feelings about the future
  • Whether you have thoughts of suicide

A definitive diagnosis may require evaluation by a mental health provider with experience in treating self-injury. A mental health provider may also evaluate you for other mental illnesses that may accompany self-injury, such as depression or personality disorders.
