At Transform Consulting Group, we make it a priority to stay current with the latest research and trends across our clients’ sectors. For example, we wrote in a previous blog about a new practice in which programs use a two-generational approach to achieve greater impact through services that support both children and adults. Often, those program models are based on research supporting their success. In this blog, we spotlight an innovative study widely used across many sectors: the Adverse Childhood Experiences (ACEs) Study.
What is the ACEs Study?
Between 1995 and 1997, Dr. Vince Felitti of Kaiser Permanente and Dr. Bob Anda of the Centers for Disease Control and Prevention (CDC) conducted surveys of more than 17,000 adults in Southern California about childhood trauma. The trauma included abuse, neglect, parental mental illness, incarceration, poverty, substance abuse, divorce or separation, and domestic violence. The researchers found that 1 in 8 respondents had 4 or more ACEs (1 point per “yes”), and 2/3 (67%) had at least 1 ACE.

What are the implications of an ACE score?
The researchers found a strong relationship between ACE scores and adverse health outcomes: higher ACE scores were associated with higher rates of illness and disease. Specifically, they reported that those who had an ACE score of four or more were 2.5 times more likely to have hepatitis, 4.5 times more likely to have depression, and 12 times more likely to attempt suicide compared to those with an ACE score of zero. In addition, those who had an ACE score of seven or more had triple the lifetime risk of lung cancer and 3.5 times the risk of ischemic heart disease, the number one killer in the United States (as of 2014).
Some reacted to these results without shock, already linking childhood trauma with higher rates of at-risk behaviors, such as smoking and drinking. However, research now shows the effect childhood trauma has on the developing brain, including inhibiting the prefrontal cortex, which is responsible for reasoning and impulse control, as well as the amygdala, which is the brain’s fear-response center.
This research is essential to know; however, the ACEs Study also shows that those who do not partake in high-risk behaviors are still more likely to develop heart disease or cancer. As Nadine Burke Harris explains in her TED Talk on this subject, this is due to the hypothalamic-pituitary-adrenal axis, the brain and body’s fight-or-flight response system. She equates this to seeing a bear in the forest and how your body recognizes the threat, activates the axis, and increases the body’s stress response (higher heart rate, opened airway, eyes dilate, etc.), so you are ready to either fight or run from the bear. This is a life-saving stress response when you are in a forest with a bear, but what happens when this stress response is triggered repeatedly due to threats in the home, or at school, or anywhere else in life?
Having this stress response triggered in a child repeatedly has been shown to negatively impact their developing brain, immune system, hormonal systems, and how their DNA is read, to the point of higher rates of illness and disease in later life, as the ACEs Study confirms.
How to Determine an ACE Score
By popular demand, Dr. Anda released to the public a PDF of the questionnaire used to identify one’s ACE score. It is a simple 10-question survey that anyone can administer in which a “yes” equates to one point. The sum of all “yes” responses is an individual’s ACE score.
Some government agencies, such as health departments are adding the ACEs questionnaire to other survey instruments administered to the public to gather information about their local population’s trauma experiences.
Using ACEs to Inform Your Work
No matter your sector or nature of work, there are a few relevant takeaways from this study.
- Adverse childhood experiences are prevalent and affect the majority of the population regardless of income, race, or other socioeconomic factors.
- ACEs negatively impact a child’s development in many ways.
- The more ACEs experienced, the greater the risk for illness and disease.
At Transform Consulting Group, we provide project management for the Early Learning Advisory Committee (ELAC), which comprises seven volunteer workgroups focused on different aspects of early learning. Multiple ELAC workgroups have used the findings from this ACEs Study to inform their work, including the Child Development and Well-Being workgroup. In 2017, this workgroup helped draft a policy on suspension and expulsion, using brain development research related to one finding from the ACEs Study, which shows that higher ACE scores negatively impact a child’s brain and social-emotional development. In addition to a carefully worded policy, the workgroup is developing resources to support its implementation, as well as information on brain development and the impact of trauma.
Another ELAC workgroup, Evaluation of Child and Family Outcomes, is looking to use data from the ACEs Study as family outcome measures, including reporting the barriers created by childhood trauma and how families are doing. The Indiana State Department of Health plans to add the ACEs questionnaire to an upcoming survey, so some Hoosiers will have information on their ACEs scores.
We at Transform Consulting Group understand the importance of staying up to date with the latest research to help our clients align with best practices and accelerate their impact. Want to learn more about how we can support your work and integrate the latest research? Contact us today!
