What are Adverse Childhood Experiences (ACEs)?
What Are Adverse Childhood Experiences?
Victoria Trauma Therapy Centre - Trauma Therapy in Victoria, BC
If you’ve ever wondered why early life experiences can shape mental health decades later, you’re not alone. Many adults seeking trauma therapy first encounter the concept of Adverse Childhood Experiences (ACEs) when exploring their own history.
Understanding ACEs can be a powerful step toward healing.
Adverse Childhood Experiences (ACEs) are potentially traumatic events that occur before age 18. These experiences can affect a child’s sense of safety, stability, and connection, and may have lasting impacts on emotional and physical health.
ACEs commonly include:
Emotional, physical, or sexual abuse
Emotional or physical neglect
Witnessing violence in the home or community
Living with a caregiver who has substance use or mental health challenges
Parental separation or divorce
A household member being incarcerated
Research shows ACEs are common and strongly linked to long-term health and mental health outcomes across the lifespan.
The ACE Questionnaire:
The ACE questionnaire asks whether each type occurred before age 18.
Each “yes” equals 1 point, creating an ACE score from 0–10.
Did you feel that you didn’t have enough to eat, had to wear dirty clothes, or had no one to protect or take care of you?
Did you lose a parent through divorce, abandonment, death, or other reason?
Did you live with anyone who was depressed, mentally ill, or attempted suicide?
Did you live with anyone who had a problem with drinking or using drugs, including prescription drugs?
Did your parents or adults in your home ever hit, punch, beat, or threaten to harm each other?
Did you live with anyone who went to jail or prison?
Did a parent or adult in your home ever swear at you, insult you, or put you down?
Did a parent or adult in your home ever hit, beat, kick, or physically hurt you in any way?
Did you feel that no one in your family loved you or thought you were special?
Did you experience unwanted sexual contact (such as fondling or oral/anal/vaginal intercourse/penetration)?
Your ACE score reflects how many types of adversity were experienced, not how severe they were.
What Does Your ACE Score Mean?
ACE scores are not diagnoses. They simply indicate cumulative exposure to childhood adversity.
However, large population studies show a clear pattern:
0 ACEs → lowest overall risk
1–3 ACEs → moderate increased risk
4+ ACEs → significantly higher risk for mental and physical health challenges
Higher ACE exposure has been linked to increased risk of:
Depression and anxiety
PTSD and trauma-related symptoms
Substance use
Chronic health conditions
Relationship difficulties
This occurs partly because chronic childhood stress can disrupt brain development and stress-response systems (often called “toxic stress”).
Important: ACEs Don’t Determine Your Future
An ACE score reflects risk, not destiny.
Many people with high ACE scores live healthy, meaningful, connected lives. Protective factors such as:
Safe relationships
Supportive adults
Therapy
Community connection
can buffer and heal the effects of early adversity.
Trauma therapy specifically targets the nervous system patterns and beliefs shaped by early experiences, helping people move from survival mode toward regulation and resilience.
Why ACEs Matter in Trauma Therapy
In trauma therapy, ACEs help us understand:
attachment patterns
nervous system sensitivity
emotional regulation challenges
self-worth beliefs
relationship patterns
Rather than labelling or pathologizing, ACEs provide context:
“What happened to you?” rather than “What’s wrong with you?”
ACEs and Healing in Adulthood
The brain and nervous system remain changeable throughout life.
Therapies such as:
somatic trauma therapy
EMDR
attachment-focused therapy
nervous system regulation work
can reduce the long-term impacts of childhood adversity and support lasting change.
