Positive childhood experiences and fewer adult psychiatric disorders

Design

Prospective birth cohort with inverse probability weighting

Population

3,499 children in the Avon Longitudinal Study of Parents and Children

Primary outcome

Any psychiatric disorder at age 24

Effect

OR 0.89 (95% CI 0.82 to 0.95) per one-point rise in positive childhood experience score

Using the Avon Longitudinal Study of Parents and Children, researchers scored 3,499 children from 0 to 10 on positive childhood experiences, such as enjoying school or feeling safe in their neighbourhood, and followed them to age 24.

Each one-point rise in the score was associated with 11% lower odds of meeting criteria for a psychiatric disorder after weighting for confounders (OR 0.89, 95% CI 0.82 to 0.95). The link was clearest for depression (OR 0.84) and present for generalised anxiety (OR 0.91). The result for psychotic disorder was inconclusive.

Most prevention work in child mental health counts adversity. This shifts some attention to what protects. It is still an association: families that provide these experiences differ in many ways that weighting cannot fully capture.

In clinic, asking about what is going well in a child's life, not only what has gone wrong, gives a fuller risk picture and points to things a family or school can build on.

• When assessing a young person, ask about school enjoyment, a trusted adult and feeling safe, as well as adversity
• Record protective factors alongside adverse childhood experiences in the history
• Encourage parents and schools to strengthen belonging and safety as part of a care plan
• The protective association was strongest for later depression

Why it matters

It suggests prevention can build protective experiences, not only remove harmful ones.

Don't overread it

This is a cohort association; it does not show that adding positive experiences prevents disorder.

The statistics, in plain English

An odds ratio of 0.89 per point means each extra positive experience on the scale was linked to about 11% lower odds. The confidence interval stops short of 1.0, so chance is an unlikely explanation, but confounding could still account for part of it.
