The short version
ACE research links greater childhood adversity with higher rates of later health problems across groups. This does not mean everyone with adversity becomes ill, or that every observed association is causal.[1][2][3]
An ACE questionnaire is an exposure inventory. It does not diagnose depression, PTSD, “toxic stress,” or a child's developmental future.[5]
The ten domains
This draft draws on the ACEs Aware adult adaptation. Its categories include parental loss; wording and coverage differ among ACE instruments.
- 01. Physical neglect
- 02. Parental loss or separation
- 03. Household mental illness
- 04. Household substance misuse
- 05. Violence between adults at home
- 06. Household incarceration
- 07. Emotional abuse
- 08. Physical abuse
- 09. Emotional neglect
- 10. Unwanted sexual contact
The landmark 1998 paper analyzed seven categories. The widely used later ten-domain checklist is not the identical questionnaire.[1] View the selected adult source

What does an ACE total measure?
A count of categories marked yes—not the number of events, severity of harm, diagnosis or biological damage. Overlapping categories can describe interconnected experiences. A skipped answer is not a no.[1][5]
Correlation versus causation
Quasi-experimental evidence supports a causal contribution of maltreatment to mental-health problems, but controlling more carefully for confounding reduces the estimated association. This is not proof that each ACE category causes every associated disease.[2]
Why individual prediction is weak
Higher scores can track average differences across groups while being poor at identifying which individual will develop illness. A cutoff is not a substitute for listening to symptoms, context and needs.[3][5]
When questions overlap
Substance misuse, violence and incarceration may occur in the same household. Counting all three can describe multiple exposures, but does not establish three independent causes or equal amounts of harm.[1][5]
Culture and experiences outside the home
Conventional household categories can miss discrimination, bullying, unsafe neighborhoods and other adversities. In a diverse Philadelphia-area sample, 13.9% reported only expanded adversities. WHO’s international tool includes peer, community and collective violence.[7][8]
What screening has—and has not—achieved
Evidence is stronger for feasibility and some process outcomes than for improved patient health. Some multicomponent prevention programs report benefits; that does not isolate the effect of an ACE score. Harms also need better measurement.[4][5]
