If Your Teen Is Self-Harming: A Guide for Parents

Teen self-harm is usually emotional coping, not a suicide attempt — but it needs immediate, calm professional attention. Call or text 988 if there is any suicidal concern.

What self-harm typically is — and what it isn't

Non-suicidal self-injury (NSSI) refers to deliberate harm to one's own body — most commonly cutting, scratching, burning, or hitting — without the intent to end one's life 1. Research indicates that roughly 17–18% of adolescents worldwide report lifetime NSSI, with rates higher in clinical settings 1. Teens who self-harm are typically using it to release unbearable emotional tension, to feel something when emotionally numb, to punish themselves, or to express pain they cannot put into words. It is a sign of significant distress, not manipulation or attention-seeking, even when it may seem that way.

It is important to note that self-harm and suicidal behavior are distinct — but they share risk factors and can co-occur. A systematic review of 64 studies found that teens with a history of NSSI face significantly higher risk for suicidal behavior, and that risk is highest in the first six months after an NSSI episode 2. Any teen who self-harms should always be evaluated.

How to respond when you first find out

The immediate response shapes what happens next. A calm, non-punitive reaction — even if the parent is terrified internally — tends to keep the teen willing to talk. Saying something like "I'm not angry, I'm worried about you and I want to understand" is more likely to open a conversation than an immediate escalation or punishment. Avoid demanding explanations right away or reacting with disgust at the wounds. The injury itself may need first-aid attention, which is a practical, non-charged entry point.

After the immediate moment, it is important not to leave this to observation alone — professional assessment is needed. Research consistently finds that parental warmth and openness after disclosure are protective factors for teens who self-harm.

What physical signs parents sometimes notice

Self-harm often stays hidden intentionally. Parents may notice: unexplained cuts, burns, or bruises — usually on the arms, inner thighs, or abdomen; wearing long sleeves in warm weather; flinching when touched on certain areas; frequently disappearing to bathrooms; or blood on clothing or tissues. A teen may also become more withdrawn, give away possessions, or express hopelessness — signs that warrant prompt attention beyond self-harm specifically.

Discovering these does not automatically mean a crisis — but it does mean the teen needs professional support and clinical assessment rather than a "wait and see" approach.

Getting professional help

A mental health professional with experience in adolescent self-harm is the appropriate next step. Dialectical behavior therapy (DBT-A) — an adaptation of DBT developed for adolescents — has the strongest evidence base for reducing self-harm in teens: a systematic review and meta-analysis of 21 studies involving 1,673 adolescents found small-to-moderate effects for reducing both self-harm and suicidal ideation compared to control interventions 3. Cognitive behavioral therapy (CBT) is also widely used.

A pediatrician can provide an initial assessment and referral. If the teen expresses any suicidal thoughts, or if the self-harm requires medical attention, the emergency department or 988 crisis line is the right first call.

What parents can do at home between appointments

Parents can help by reducing access to common means of self-harm (blades, lighters) without shaming the teen; being consistently present without hovering; checking in regularly without interrogating; and letting the teen know the parent is not going anywhere. Avoid bargaining ("promise me you'll stop") — the teen likely wants to stop and cannot yet, and broken promises add guilt. This is a time when the family may also benefit from their own support to process the fear and distress a parent naturally experiences.

The NIMH notes that self-harm behaviors in older children and adolescents are among the key warning signs that warrant professional evaluation 4. Seeking that evaluation is not overreacting — it is appropriate care.

Common questions

Is self-harm always a sign of suicidal intent?

Not usually. Most teens who self-harm are not trying to die — they are trying to manage overwhelming feelings. However, self-harm and suicidal behavior can coexist. A systematic review found that teens with a history of NSSI face significantly elevated risk for suicidal behavior, with the highest risk in the first six months after an episode. Always take any mention of wanting to die seriously, and have the teen professionally evaluated.

Should I tell other family members or the school?

This depends on the circumstances and is worth discussing with the clinician working with your teen. The teen's trust is important to preserve — involving others without the teen's knowledge can damage that trust. Schools may need to know for safety planning purposes, but the how and when of disclosure is best guided by the treating clinician.

My teen says self-harm is the only thing that helps them cope. What do I say?

Validating that they are in real pain — "I believe it helps you feel better in the moment" — while holding the space open for finding other ways is a reasonable stance. Arguing against it directly rarely works. A therapist skilled in DBT-A or other evidence-based approaches for adolescent self-harm can help the teen build a different set of coping tools over time.

When to get care right away

  • —Teen expresses any suicidal thoughts or desire to die
  • —Self-injury is deep, actively bleeding, or appears infected
  • —Teen is unresponsive, extremely intoxicated, or unable to be engaged
  • —Recent or possible overdose of any substance or medication

For suicidal thoughts or a psychiatric emergency, call or text 988 (Suicide and Crisis Lifeline) immediately. For a physical medical emergency, call 911 or go to the nearest emergency department.
