Understanding Childhood Trauma, ACEs, and Resilience: A Parent's Guide
How early adversity can affect your teen — and what helps young people heal.
Something changed in your teen, and you cannot quite explain it. Maybe they are always on edge — startled by small things, quick to anger, unable to relax. Maybe they have shut down — withdrawn, flat, unreachable. Maybe they cannot focus, their grades have dropped, they do not trust adults, or their body is constantly in distress with headaches and stomachaches that have no medical explanation. You may not use the word “trauma.” You may not even know whether something traumatic happened. But you know something is affecting your child, and you want to understand what it is and how to help. This guide explains what childhood trauma and adverse childhood experiences (ACEs) are, how they affect the brain, body, and behavior of teenagers, and — most importantly — what you can do about it. Trauma is not a sentence. It is a starting point for understanding, and for healing.
Key things to know about childhood trauma and ACEs:
Adverse Childhood Experiences (ACEs) are specific categories of adversity that increase risk over time. Trauma is how a child experiences and responds to those events. Toxic stress is the chronic activation of the stress system without enough buffering support.
Three in four U.S. high school students report at least one ACE. Idaho’s ACE numbers exceed the national average. This is common, not rare.
Trauma in teens often shows up through behavior, mood, body, school, and relationships — not through a teen saying “I experienced trauma.”
The impact of ACEs is not destiny. Three elements can shift the balance: positive childhood experiences, resilience built through developmental relationships, and professional therapy.
Evidence-based therapies — including TF-CBT, EMDR, DBT, and equine-assisted therapy — can reduce the weight of past adversity and, in some cases, begin to reverse its biological effects.

How Trauma Shows Up in Teens
What parents should know
What this article covers:
- Coping skills replace self-harm most effectively when they serve the same function — a strategy for emotional overwhelm may not work for numbness, and vice versa.
- Takeaway 2 Short Text Skills must be practiced before the crisis, not introduced during one. A coping strategy used for the first time mid-urge rarely works.
- Takeaway 3 Short Text No single strategy works for every teen. Individualization matters — your teen should build a personal toolkit of 5–10 options they have tested and trust.
- Takeaway 4 Short Text Coping skills are not a substitute for therapy. They manage the moment; therapy addresses the cause.
- Takeaway 5 Short Text Using a coping skill instead of self-harming — even imperfectly — is meaningful progress worth acknowledging.
Why Matching the Skill to the Function Matters
Not all coping skills work for all reasons teens self-harm. A teen who cuts to release overwhelming emotion needs strategies that discharge intensity. A teen who self-harms to feel something through numbness needs strategies that generate sensation. Handing a generic list of “healthy coping skills” to a teen without matching the skill to the need is one of the most common reasons replacement strategies fail.
The categories below are organized by the function the self-harm is serving. If you are unsure which function applies to your teen, see our resource page: Why Teens Self-Harm.
When the urge is about releasing overwhelming emotion
These strategies work by discharging the intense emotional energy that self-harm would otherwise release:
Intense physical exercise -
sprinting, jumping jacks, pushing against a wall with full force, punching a pillow. The goal is to move the energy out of the body.
Holding ice cubes tightly in a closed fist or pressing them against the inner wrist.
The intense cold produces a strong physical sensation that can break the emotional spiral without causing injury.
Submerging hands or face in very cold water, or taking a cold shower.
The “dive reflex” activates the parasympathetic nervous system and rapidly reduces emotional arousal.
Screaming into a pillow or tearing up paper, old magazines, or cardboard -
physical release without physical harm.
Writing out the emotion in raw, unfiltered language -
not journaling for insight, but venting on paper. The paper can be destroyed afterward.
A coping skill that serves the same function as the self-harm is far more likely to work than a generic suggestion to “try deep breathing.”
When the urge is about feeling something through numbness
These strategies generate physical sensation or emotional activation that breaks through disconnection:
Snapping a rubber band against the wrist — a brief, sharp sensation that does not cause lasting harm.
Holding something frozen, biting into a lemon or chili pepper, smelling something pungent like peppermint oil or ammonia. Strong sensory input can interrupt dissociation.
Vigorous physical movement — dancing, running, jumping. The body’s activation produces sensation and emotion.
Drawing on skin with a red marker where they would normally cut. The visual mimics the appearance without the injury and can satisfy the urge for some teens.
Touching textured objects — rough fabric, bark, sandpaper — to ground through tactile sensation.
Touching textured objects — rough fabric, bark, sandpaper — to ground through tactile sensation.
When the urge is about self-punishment
These strategies interrupt the self-blame cycle and redirect toward self-compassion. This is often the hardest function to replace because the teen believes they deserve the pain:
Writing a letter to themselves from the perspective of someone who loves them - a friend, a grandparent, a therapist. The exercise externalizes compassion.
Reading or listening to something affirming. Pre-selected quotes, voice memos from loved ones, or a list of things they are proud of, assembled during a calm moment
Challenging the thought directly: “What would I say to a friend who felt this way about themselves?” The answer is almost never “You deserve to be hurt.”
Physical self-care as a counter-action: taking a warm bath, applying lotion to the skin, wrapping themselves in a blanket. Treating the body with gentleness contradicts the punishment impulse.
When the urge is about regaining control
These strategies provide a sense of agency and mastery without self-injury:
- Organizing something — a drawer, a playlist, a workspace. The act of imposing order on a small area can reduce the sensation of chaos.
- Making a deliberate choice about something: what to eat, what to wear, where to go for a walk. Exercising agency in safe domains.
- Creating something — art, music, writing, cooking. Creation is an act of control that produces something rather than destroying something.
- Setting and completing a small, concrete goal: cleaning a room, finishing a task, solving a puzzle. The sense of completion counteracts helplessness.
You do not need a diagnosis, a referral, or a clear picture of what’s going on. Many families start therapy with exactly the kind of uncertainty you may be feeling right now. A professional can help determine whether what you are seeing is a rough patch or a developing mental health concern — and either way, your teen benefits from having a safe, neutral space to process what they are going through.
When the urge is about communicating distress
These strategies help teens express pain directly rather than through their body:
Texting or calling a trusted person from the safety plan:
“I’m having a really hard time right now.” The act of reaching out directly replaces the indirect communication of self-harm.
Writing what they need and showing it to someone:
“I need help. I don’t know how to say it out loud.”
Using an emotion rating system with a parent -
a simple 1–10 scale, a color system, or emoji cards. This gives language to distress without requiring articulation.
Journaling the unsaid:
writing what they wish they could tell someone, even if they never share it. The act of forming the words is itself a form of expression.
How to Build Your Teen’s Personal Toolkit
The most effective approach is to sit with your teen during a calm moment — not during a crisis — and explore which strategies feel realistic to them. No one else can choose the right coping skills for your teen. They need to select strategies that match their specific experience, test them in low-stakes situations, and build confidence that the strategy works before they need it under pressure.
Aim for a list of 5 to 10 options written down and accessible — on their phone, on an index card in their wallet, taped inside a drawer. The list should include at least one option for each function they experience. When the urge hits, decision-making capacity drops. A pre-made list removes the need to think of alternatives in the worst possible moment.
An Important Note
Coping skills manage the moment. They do not treat the cause. A teen who is successfully using ice cubes instead of cutting is making real progress — but they still need therapy to address the emotional pain that is generating the urge in the first place. These strategies work best as one element of a broader treatment plan, not as a standalone solution.

Common questions

Answers to some of the questions families often ask when trying to understand these challenges.
Why don’t coping skills always work?
The most common reasons: the skill does not match the function (a calming technique offered to a teen seeking sensation), the skill was introduced during a crisis rather than practiced beforehand, or the emotional intensity exceeded the skill’s capacity. When skills fail, it usually means the match or the timing needs adjustment — not that the teen is failing.

Answers to some of the questions families often ask when trying to understand these challenges.
When your teen is showing multiple symptoms across domains (emotions, behavior, body, school, relationships) that have persisted for weeks or months, and when the patterns seem out of proportion to current stressors, toxic stress may be a factor. The key indicator is chronic dysregulation, a nervous system that seems stuck in threat mode, unable to return to calm even when the environment is safe. A professional evaluation can determine whether trauma and toxic stress are contributing.
Yes. Evidence-based therapies like TF-CBT and EMDR have strong research support for treating trauma in adolescents. There is also growing evidence that therapy can begin to reverse some of the biological changes caused by toxic stress, a study of trauma-focused CBT showed measurable restoration of epigenetic changes in genes affected by chronic stress. Therapy does not erase the past, but it can reduce the weight of its impact.
PCEs are experiences that build a child's sense of belonging and connection. Research identifies seven core PCEs: being able to talk with family about feelings, having family stand by you during hard times, participating in community traditions, feeling a sense of belonging in school, having supportive friends, having at least two non-parent adults who genuinely care, and feeling safe and protected by an adult at home. PCEs do not erase trauma, but they moderate its long-term impact.
No. ACEs increase risk, but they do not determine outcomes. The research is clear that positive childhood experiences, resilience built through developmental relationships, and professional therapy can significantly reduce the long-term impact of adversity. Many people with high ACE scores lead healthy, fulfilling lives, especially those who received support.
Yes. Trauma is defined by its impact on the individual, not by the number of adversities. A single overwhelming experience, an assault, a car accident, the sudden death of someone close, or chronic bullying, can produce significant trauma symptoms even if the teen's formal ACE score is low. The original 10 ACE categories also do not capture many common adolescent adversities like bullying, community violence, or discrimination.
ACEs are categories of adverse experiences that increase risk. Trauma is how a child's mind and body respond to overwhelming experiences. A child can have ACEs without developing trauma symptoms (if protective relationships were strong), and can have trauma from experiences not on the original ACE checklist. The ACE score is a useful risk indicator, not a diagnosis.
ACEs Are Not a Sentence
If you have read this far and recognized your teen in these descriptions, you may be feeling overwhelmed. You may be thinking about things that happened in your family, or things you did not know about, or things you could not prevent. Here is what you need to know: the fact that adversity happened does not mean your teen is broken. The research that identified the problem also identified the solution. Positive experiences, resilient relationships, and professional therapy can shift the balance — not by erasing the past, but by changing its power over the present. What happens next matters more than what happened before.

How to support your teen in building and using coping skills:
01
Build the toolkit together during a calm moment
Do not wait for a crisis. Sit with your teen when things are relatively stable and explore which categories apply to them and which strategies feel realistic. Let them lead — they know their experience better than you do. Write the list down and make it accessible.
02
Stock the house with what they need
If ice cubes are on the list, keep ice available. If art supplies help, make sure they are accessible. If physical exercise works, keep a space clear. Removing barriers between the urge and the coping skill makes it more likely the skill will be used.
03
Acknowledge every attempt to use a skill
Even if the skill did not fully work, even if your teen still self-harmed afterward, the fact that they tried an alternative first is meaningful progress. Name it: “I noticed you went for a run before things got bad. That matters.” Recognition reinforces the new pattern.
04
Do not treat coping skills as a substitute for therapy
Coping skills manage the moment. Therapy addresses the cause. Your teen needs both. If you find yourself relying on the toolkit instead of pursuing professional support, the toolkit is doing too much. It is a bridge, not a destination.
