Adverse Childhood Experience (ACE) Questionnaire

Man at desk completes written testThe Adverse Childhood Experience (ACE) Questionnaire is a 10-item self-report measure developed for the ACE study to identify childhood experiences of abuse and neglect. The study posits that childhood trauma and stress early in life, apart from potentially impairing social, emotional, and cognitive development, indicates a higher risk of developing health problems in adulthood.

Development of the ACE Questionnaire

The ACE study originated in 1985 in Dr. Vincent Felitti’s obesity clinic in California. Felitti was frustrated that a number of the people in his program dropped out, even though they were successfully losing weight. Upon reviewing the history of the people who dropped out, Felitti found that many people in his clinic had a background of adverse childhood experiences, such as physical or sexual abuse. He began to wonder if obesity might be, for some people, an unconscious defense that lingered as a result of adverse childhood experiences.

Researchers found that weight gain was indeed the way some of those who had experienced childhood abuse had attempted to protect themselves, whether consciously or unconsciously, from further incidences of abuse, and that they left Felitti’s program due to feelings of anxiety that followed their weight loss.

Following the results of this study, the Centers for Disease Control and Prevention, which was exploring the psychosocial origins of various public health concerns such as alcohol abuse, obesity, and nicotine use, paired up with Kaiser Permanente to develop one of the largest epidemiological studies in the United States. The ACE Study aimed to identify the childhood trauma experiences of more than 17,000 adult participants, who underwent a physical examination and completed the ACE Questionnaire, in order to determine whether there truly was a link between adverse experiences in childhood and health concerns, both physical and mental, later in life.

Findings of the Study

The study found that nearly 40% of participants had been exposed to two or more of the different categories, and 12.5% reported exposure to at least four categories. In other words, the study showed that adverse childhood experiences were more common than had previously been recognized or acknowledged by research and medical findings. The study also identified a direct link between the ACE score and adult chronic illness, as well as emotional and social issues such as depression, domestic violence, and suicide.

For example, an individual with an ACE score of four or higher was 260% more likely to have chronic obstructive pulmonary disease than someone with a score of 0, 240% more likely to contract hepatitis, 460% more likely to experience depression, and 1,220% more likely to attempt suicide.

Using the ACE Questionnaire

The questionnaire helps researchers and mental health professionals identify childhood abuse and neglect and family dysfunction such as domestic violence, incarceration, and alcohol and drug issues.

The survey consists of ten questions. Each affirmative answer is assigned one point. At the end of the questionnaire, the points are totaled for a score out of ten, which is known as the ACE score.

Some sample questions:

  • Did a parent or other adult in the household often push, grab, slap, or throw something at you?
  • Was a household member depressed or mentally ill or did a household member attempt suicide?
  • Did you often feel that you didn’t have enough to eat, had to wear dirty clothes, and had no one to protect you?

The questionnaire has many different applications and may be administered by clinicians to better understand the trauma history of people who are experiencing:

  • Domestic violence
  • Drug and alcohol issues
  • Incarceration
  • Mental health conditions and suicidal thoughts
  • Chronic health conditions

How the ACE Questionnaire Relates to Physical and Mental Health

The questionnaire identifies major risk factors that may lead to the development of health and social issues among people in the United States. Besides suggesting that an individual may be more likely to experience health issues later in life, this questionnaire also shows how childhood trauma affects the mortality rate: The life expectancy of an individual with an ACE score of six or more may be reduced by up to 20 years.

Because the ACE Study suggests that there is a significant link between adverse childhood experiences and chronic disease in adulthood, including heart disease, lung cancer, diabetes, and autoimmune diseases, the questionnaire may be able to help those who have a high ACE score become more informed about their increased risk factor for health issues. It could also encourage them to seek treatment or therapy if they have not already done so.  Additionally, the study highlights how these childhood experiences influence the possible development of mental health issues in adulthood and may serve to assist mental health professionals in better understanding certain mental health concerns.

The connection between adverse childhood experiences, social issues, and adult mental and physical health might also be used to help inform programs and health policies that support prevention of these issues and recovery from them.

    The ACES test is skewed in wording to exclude the 4 to 6% of people who’s mother or stepmother was the abusive parent. It also excludes anyone who had a sexually abused sibling or had the trauma of siibling incest by other siblings than themselves.

  • Renee

    Questions 1-3 refer to any abusing adult in the household. But on yor second point yes I agree, there ought to be a question included about abuse by siblings. That also reflects on the parents’ lack of communication and awareness of the family dynamics.

    Hi! I am suffering from PTSD and I realized that it caused by the ACEs. This article helps me so much to understanding about my childhood event, my PTSD, and my horrible story in my life. I write my story here, because I think words is one of the best and inexpensive therapy. Thank you for helping other people :)

  • Sharon M,

    I scored 9. No one went to prison. I am 72 and carry alot of baggage. Been through whole bunch of self help stuff. Adult Children of Alcoholics which made me cry alot and was a trigger that made me angry! Others in my family stuffed it! There were 5 of us.Everything applies to us as far as health issues. My oldest brother passed at 73. He caught ALL of the Hell from aunts uncle granny and parents. My next brother and I married 4 times. Next after me was the pet! She managed to live under the roof of our parents for 20 plus years. Example (she got a piano and lessons as a child ). I was 6 years older and was chosen to play in the high school band. I got a flutiphone.LOL! Her fingers were longer and she took typing lessons. I got my last whooping with a belt at 18. I was grown and working. No one told me that I could leave. So I was forced to get married to the only boyfriend that I was allowed to have from age 15. My parents never allowed me to date even though other young men’s parents asked permission. NONE WERE EVER ACCEPTED! I did exactly what the control freaks wanted. I was 26 and when my husband was cheating. I got divorced! I was FREE and men liked me! I was wild and didnt marry for 10 years. My baby sister got her last whooping at 17 and married shortly after. She was married twice. She is 12 years younger than me. Let me tell you about our parents who fought each other with knives/guns or whatever was their weapon of choice scissors/rocks etc. They would split and get back together for more than 50 year. We didnt all live together til I was 7 years old! My brothers lived with Dad’s mom and I was left with my mom’s mom. I was born 9 months and ONE DAY after they got married! Dad was married before and had my 2 brothers. He was a Baptist deacon and a 33 degree Mason. The pillar of the community later in life and during the time we were screwed up! People who know me always tell me that I
    am strong. I guess no one ever knew me at all. What I am is bitter! HELP ME JESUS. I’m still here 9 questions later. None of my school teachers were worth a darn either. I was in grade 3 when school teacher, Ida Mae Mulllins grabbed me by the hair for walking between her and another teacher! Today we have ACE . I have to ask, Does Anyone Give a Damned!! I doubt it! That’s why a little 3 year old girl’s babysitter has put her in the hospital in Cincinnati today! She is brain dead and not expected to live! BTW I was molested by the landlord at age 7.

    I would find a good therapist. If you don’t feel a match/connection with the therapist you see try another therapist. Also, if you know any nurses they probably could recommend a good therapist at the hospital where they work. That’s only if you are experiencing problems in your life.

    It frustrates me that the questionnaire only addresses spousal abuse by fathers, but not by mothers. My mother was abusive towards my father and the only time he ever pushed even was if she was coming towards one of us kids.

    I’m a 67-year-old, African American, cis-gendered woman. Back in the early 60’s, I was one of 100 black children sent to integrate schools in the New York neighborhood called Bensonhurst. Today I’m a member of an organization that brings together people of different races who want to heal racism. I don’t recall where I found out about the ACES study but just now when I took the test, I scored an 8. I was abused as a child, including sexual abuse, and survived by becoming a multiple personality. I lived as a multiple until I was 50 years old. I have also been diagnosed with PTSD, depression and agoraphobia. I’m now looking at my past in terms of the affects of racism. Has anyone done an ACES study that asks questions about the abuses of racism? Is anyone interested in designing such a study? I’ve also suffered from obesity most of my life. Back in 2011, I joined Weight Watchers and ended up losing 70 pounds. I kept it off until 2016 when a fall resulted in a fractured hip and hip replacement surgery. I slowly lost control of my eating after that and have gained back 25 of those 70 pounds. I know now that the accident was a trigger for feelings that I was no longer safe. I’ve been in therapy most of my life so I’m not looking for a therapist. I am, however, interested in understanding the wounds from racism. I’d appreciate being pointed in the direction of any studies about that.

    Some good info here on early childhood issues manifest later in life. The first 4 yrs are crucial. That being said, there are some criticisms I have:
    1. The Q on physical abuse of a female adult in the child’s family is horribly misogynist in that it affirms the narrative of the female victim. Most notibly is the skirting of the issue of very real violence in other forms (mental, physical).
    2. The Q on parental depression seems to suggest that there could be some other reaction to a divorce, so really you just got 2 points on those questions.
    Otherwise i like ghe direction this is going.

  • Matthew

    November 25th, 2019 at 10:36 PM

    @ G – I 100% agree that the question on domestic abuse is horribly skewed and sexist- it does not take into account the many female perpetrators and male victims of domestic violence, and how many children had to witness that. I have seen other ACE studies that simply list it as “intimate partner violence”, but considering the CDC one is the main one it skews people’s perception of what an ACE is.

    @Fran- there actually is an ACE scale that includes racism – does many studies and profiles of different areas on ACEs, and one of them is “Treated or judged unfairly due to race/ethnicity”. Here is an example of one, though you can find many more on their website (I’m not trying to promote them, but you may find them helpful):

    I understand the concept of the ACES. The parents would have had ACES themselves. I would their parents and so on back through the generations. Does moving from address to address and changing schools take its toll? I’m guessing so. As, with every house move, there’s a loss and a gain, but I’m betting the loss woukd be greater for a child. The bottom line is, no one escapes trauma. Life is traumatic. I’m hoping THE ACE study gives people understanding, not a chance to blame.

    Yes, my score was 10, I was suppose to get a 0

    Understand the concept of Aces, leaves out if there is a difference between pervasive acts v. benign disagreements or occurrences [ie saw Dad drunk one time or parents argue over money] that could occur in most families (which people looking for reasons would say caused all their adult problems)
