The effects of complex trauma can take parenting a teenager is challenging to overwhelming. You might see behaviors or struggles that seem confusing, frustrating, or even out of control. It’s not your fault, and your teen isn’t “just being difficult.”

In Complex Trauma in Children and Adolescents, by Joseph Spinazzola and colleagues seven areas where trauma deeply impacts kids and teens are identified. Understanding these effects can help you support your teen with compassion and practical strategies. Let’s dive into these seven areas and explore what you can do.

1. The Effects of Complex Trauma on Attachment

Trauma makes trusting others feel risky, even with family. Your teen might push you away, cling too tightly, or both.

Signs of Attachment Struggles

• Avoids or rejects comfort, especially during tough times.
• Becomes overly dependent or fears being abandoned.
• Struggles to form or maintain friendships.

How Parents Can Help

• Be consistent. Show your teen they can count on you.
• Reassure them that their feelings and needs are valid.
• Don’t take their behavior personally—it’s about their fear, not your actions.

2. Biology: The Physical Effects of Complex Trauma

Trauma affects the body as much as the mind. Teens often show physical symptoms tied to their stress.

Signs of Physical Effects

• Chronic headaches, stomachaches, or unexplained fatigue.
• Sensitivity to light, sound, or touch.
• Difficulty falling or staying asleep, including frequent nightmares.

How Parents Can Help

• Create a calm, predictable environment at home.
• Explore sensory tools like weighted blankets or noise-canceling headphones.
• Partner with healthcare providers who understand trauma’s physical impact.

3. Emotional Regulation and the Effects of Trauma

Teens with trauma often struggle to handle their emotions. They might seem moody, explosive, or shut down completely.

Signs of Emotional Struggles

• Overreacts to small frustrations or stressors.
• Bottles up emotions until they explode later.
• Has difficulty calming down after being upset.

How Parents Can Help

• Stay calm and steady, even when emotions run high.
• Teach simple coping strategies, like deep breathing or grounding exercises.
• Validate their feelings: “It’s okay to feel what you’re feeling.”

4. Dissociation: An Invisible Effect of Trauma

When things feel overwhelming, dissociation helps teens mentally “check out.” It’s a survival mechanism, not laziness or avoidance.

Signs of Dissociation

• Seems zoned out or disconnected during conversations.
• Has memory gaps or trouble recalling daily events.
• Appears spacey, unfocused, or detached from reality.

How Parents Can Help

• Use grounding techniques, like asking them to name three things they see or hear.
• Keep routines simple and avoid overwhelming situations.
• Be patient and supportive—dissociation isn’t defiance.

5. Behavioral Control and the Effects of Trauma

Trauma makes it hard for teens to control their impulses. They might react instinctively rather than thoughtfully.

Signs of Behavioral Struggles

• Lashes out in anger or becomes defiant.
• Runs away, hides, or avoids responsibilities.
• Struggles to follow rules or routines consistently.

How Parents Can Help

• Set clear, consistent boundaries—predictability creates safety.
• Praise positive behaviors to reinforce them.
• Teach alternatives to impulsive reactions, like stepping away to cool down.

6. How Trauma Impacts Learning and Cognition

A brain under constant stress struggles to focus, process, or remember information. This can make school a major challenge.

Signs of Cognitive Effects

• Has trouble concentrating, even on favorite activities.
• Struggles to follow instructions or complete assignments.
• Falls behind academically despite effort and ability.

How Parents Can Help

• Break tasks into small, manageable steps.
• Collaborate with teachers to create a supportive learning environment.
• Celebrate effort and progress, not just results.

7. Self-Concept: Trauma’s Impact on How Teens See Themselves

Trauma can make teens feel like they’re unworthy or broken. These beliefs are deeply rooted but can change with support.

Signs of Self-Concept Struggles

• Negative self-talk like “I’m not smart enough” or “Nobody likes me.”
• Avoids trying new things due to fear of failure.
• Overcompensates by trying to please everyone.

How Parents Can Help

• Counter negative thoughts with specific, sincere praise: “You handled that situation really well.”
• Encourage activities that build confidence, like art, sports, or volunteering.
• Remind them daily that they’re loved, no matter what.

Moving Forward

Therapy, especially “bottom up” trauma-focused approaches like EMDR or somatic work, can be life-changing for teens dealing with trauma. And don’t forget to care for yourself, too. Parenting through trauma is hard work, and you don’t have to do it alone.
