The Adverse Childhood Experiences (ACE) Questionnaire is a 10-question self-assessment that measures childhood exposure to trauma, neglect and household dysfunction. Each “yes” answer counts as one point, giving you a final ACE score between 0 and 10. A higher score reflects more childhood adversity, which decades of research has linked to specific risks in adult life, including addiction, depression, anxiety, and several chronic physical illnesses.
If you have been searching for the ACE questionnaire because something about your patterns, your drinking, your moods, your relationships, or your physical health isn’t adding up, this test exists for exactly that question. Childhood does not stay in childhood. The body and the brain carry early experiences forward, and the ACE score is one of the most validated ways to measure how much that history might be shaping your present.
What Is the ACE Questionnaire?
The ACE Questionnaire was developed from a landmark 1998 study by the CDC and Kaiser Permanente that surveyed over 17,000 adults about their childhood experiences and current health. The researchers found that exposure to specific types of childhood adversity correlated strongly and predictably with adult addiction, depression, suicide attempts, cardiovascular disease, and earlier mortality. The questionnaire is the simplified screening tool that came out of that research.
It asks ten yes/no questions covering ten categories of adverse childhood experiences. Each “yes” counts as one point. The score is the total.
The 10 ACE Categories
Before the age of 18, did you experience any of the following:
- Emotional abuse: a parent, stepparent or adult in your home repeatedly swore at you, insulted you, put you down or humiliated you, or acted in ways that made you afraid of being physically hurt
- Physical abuse: a parent, stepparent or adult in your home hit, slapped, pushed, grabbed, or threw something at you, or hit you hard enough to leave marks or cause injury
- Sexual abuse: an adult or someone at least five years older touched or fondled you sexually, asked you to touch them sexually, or attempted or had any kind of sexual contact with you
- Emotional neglect: there was no one in your family who made you feel important or special, loved, or who looked out for you, or your family did not feel close, supportive or loving
- Physical neglect: there often wasn’t enough to eat, your parents were too drunk or high to take care of you, or you had no one to take you to the doctor when needed
- Parental separation or divorce: your parents were ever separated or divorced
- Domestic violence: a parent or stepparent was pushed, grabbed, slapped, threatened or repeatedly hit by another adult in the household
- Substance abuse in the household: you lived with someone who was a problem drinker, an alcoholic, or who used street drugs or misused prescription medications
- Mental illness in the household: a household member was depressed, mentally ill, or attempted suicide
- Incarcerated household member: a household member went to prison
Your ACE score is the total number of “yes” answers, from 0 to 10.
What Does Your ACE Questionnaire Score Mean?
Your ACE score sits on a continuum. The CDC’s score interpretation framework groups outcomes into three risk levels based on the score and whether health conditions are already present.
| ACE Score | Risk Level | What It Suggests |
|---|---|---|
| 0 | Low risk | Limited exposure to the specific adversities the test measures |
| 1 to 3 | Intermediate risk | Some childhood adversity, with elevated risk for trauma-linked conditions if combined with current health symptoms |
| 4 or higher | High risk | Substantially elevated risk for addiction, depression, anxiety, suicide attempts, heart disease, and earlier mortality |
| 5 or higher | Very high risk | An eight-fold increase in alcoholism risk compared with score 0 |
| 6 or higher | Very high risk | Estimated 20-year reduction in life expectancy compared with score 0 |
These figures come from the original CDC-Kaiser data and have been replicated across dozens of follow-up studies. The numbers describe risk at a population level. They are not destiny. A high ACE score does not predict your future, it identifies which physiological and psychological systems are most likely to need attention.
Why the ACE Score Matters for Addiction
The most important finding from the ACE research, particularly for anyone reading this through the lens of their own substance use, is the strength of the link between childhood adversity and adult addiction. A score of 4 or more doubles the risk of alcoholism. A score of 5 or more produces an eight-fold increase compared with a score of 0. These are some of the strongest predictive relationships in addiction medicine.
The mechanism is not mysterious. Childhood adversity disrupts the developing stress response system, which leaves adults less able to regulate distress, more reactive to emotional pain, and more reliant on external regulators.
Alcohol and drugs are highly effective short-term emotional regulators. People with high ACE scores are not weaker or less moral than people with low scores. They are managing a nervous system that was shaped by experiences a child should never have had to manage at all.
This is why a high ACE score in someone with addiction is not a curiosity. It is the clinical data that explains why willpower-based recovery so often fails for trauma survivors. Treatment that addresses the addiction without addressing the underlying trauma is treating half the problem.
If Your Score Suggests Trauma Is Driving Your Substance Use
If your score suggests trauma as a driver of your substance use, Changes integrates trauma-informed care into our programme. We treat addiction as the survival strategy that grew from earlier wounds, not as a moral failing or a willpower problem. Our clinical team includes psychiatrists, psychologists and counsellors trained in the trauma-addiction interaction, and our mental health and addiction rehab programme is built specifically to treat both at the same time.
Most addiction programmes treat the substance use first and the trauma “later”, which in practice often means never. The result is high relapse rates among trauma survivors, because the underlying driver was never addressed. Changes does the opposite. We integrate trauma-informed therapy, psychiatric care for mood and anxiety conditions, and the full clinical addiction programme in the same treatment environment, because addiction and trauma do not heal in separate rooms.
If your ACE score has put words to something you have been carrying for a long time, the next step is a clinical conversation with someone who understands what to do with that information.
