What Is the Adverse Childhood Experiences [ACEs] Study and What Is Its Significance?
The ACEs Study [published in 1998] is important because it found links between childhood trauma and long-term health, behavior and social consequences among adults.
How Were These Links Discovered?
Per the below infographic, the authors – from Permanente Medical Group (Kaiser Permanente), Centers for Disease Control and Prevention (CDC), Emory University and the University of Arizona – asked adult patients about any exposure they had as a child to the following:
- Recurrent physical abuse
- Recurrent emotional abuse
- Contact sexual abuse
- Alcohol and/or drug abuser in the household
- An incarcerated household member
- Someone in the household who is chronically depressed, mentally ill, institutionalized or suicidal
- Mother is treated violently
- Parents are separated or divorced
- Emotional neglect
- Physical neglect
A comparison to the participant’s adult health status was made, and strong links were found between high ACE scores (on a scale of 1 to 4+, having more than 2 or more adverse experiences) and impaired health/mental health.
In addition to the negative impact adverse childhood experiences are likely to have on a person, this graphic also shows the prevalence of ACEs and the three primary types of ACES: abuse, neglect and household dysfunction.
The ACE study has provided social workers and other clinicians with an invaluable tool to assess the types of trauma an individual had as a child. It is a way to begin to discuss, “What happened?” with a person. ACEs help establish a history that de-pathologizes the person and enhances a trauma-informed practice.
Below is a pyramid chart created by the CDC that illustrates the gaps that still exist in our knowledge of the full impact of ACE , emphasizing the need for ongoing research.
Longitudinal studies of the ACE Study participants continue through Kaiser and the CDC.
