Mothers' 1-Second Vocal Responses Linked to Child ADHD Risk
The timing of maternal vocal responses, measurable in infancy, may serve as an early indicator for later ADHD and disruptive behavior disorder diagnoses, potentially guiding early support.

A University of Glasgow-led analysis of UK cohort data found that the rate at which mothers vocally respond to their infants within one second is associated with later psychiatric diagnoses. Each 10-point increase in that rate was linked to roughly 17% lower odds of any psychiatric diagnosis by age 7, with stronger associations for ADHD and disruptive behavior disorders. The researchers call the findings preliminary.
The study drew on the Avon Longitudinal Study of Parents and Children, which filmed mothers and infants looking at a picture book in a room styled like a home living room when the children were 12 months old. At age 7, the same children were assessed for psychiatric conditions using the Development and Wellbeing Assessment. The analysis covered 158 mother-infant pairs, including 55 children with a diagnosis and 103 controls.
Researchers timed each vocalization and measured the gap between an infant's sound and the mother's next vocal response. The key metric was the proportion of responses within one second. For every 10-point rise in that proportion, the estimated likelihood of any psychiatric diagnosis fell about 17%, with ADHD down about 21% and disruptive behavior disorders down about 20%. No such link appeared for autism or emotional disorders.
