Adverse childhood experiences (ACEs)
A count of ten categories of childhood adversity: abuse, neglect, and household dysfunction such as parental addiction, mental illness, violence, incarceration or separation. Higher counts go with worse adult health and behaviour.
What drives it
Shows that childhood adversity has dose-dependent effects across a population. Useful as a prompt to ask about history; poor as a verdict on anyone in particular.
How it shows
Work
Not visible as a number. Shows indirectly as wariness of authority, difficulty trusting, overwork, or in high-functioning leaders who never mention their history. Many people with high scores are exceptional in a crisis because chaos is familiar.
Relationships
Raised risk of difficulty with trust and conflict, and of addiction in oneself or one's partner; also of choosing partners who recreate the home's unpredictability.
Self
Counting your own categories can clarify your history; it says little about where you will end up.
What tells it apart
Complex PTSD: Complex PTSD is a diagnosis based on current symptoms (re-experiencing, dysregulation, a damaged self-concept); an ACE score counts past events whether or not symptoms exist.
Childhood emotional neglect: The ACE list captures only gross neglect; subtle emotional neglect often scores zero yet shapes adults heavily.
A test
Ask about the history, then look separately at current functioning; don't infer one from the other.
Questions to carry
- What changes in how someone’s behaviour today gets read once their childhood is known?
- When I picture my early years as a tally, what does the number leave out?
How strong the research is
moderate. Population-level links between ACE counts and later health are robust; as a score for an individual it predicts poorly, and it ignores severity, timing and protective relationships.
