Largest Investigational Study on
Childhood Trauma

"When people are behaving in apparently self-destructive ways, it’s time to stop asking what’s wrong with them, and time to start asking what happened to them.” 

- Dr. Robert Anda and Dr. Vincent Felitti, Founders of the Adverse Childhood Experience Study

The CDC-Kaiser Permanente’s Adverse Childhood Experiences Study (ACE Study) links 10 types of childhood trauma with the adult onset of chronic disease, mental illness, and violence.

The 10 ACEs are: physical, sexual, emotional abuse; physical, emotional neglect; living with a family member who’s addicted to alcohol or other drugs, is depressed, has other mental illness or who’s imprisoned; witnessing a mother's abuse; divorce or separation.

For people who have four types of childhood adversity — an ACE score of 4 — alcoholism risk increases 700 percent; attempted suicide increases 1200 percent. Heart disease and cancer nearly double. People with high ACE scores have more marriages, more broken bones, more depression, more prescription drug use, more obesity.


"Understanding many of the fundamental processes that underlie traumatic stress opens the door to an array of interventions that can bring the brain areas related to self-regulation, self perception, and attention back online. We know not only how to treat trauma but also, increasingly, how to prevent it.”

- Bessel van der Kolk, MD
