Parental stress depletes the inhibitory resources that normally prevent discipline from escalating into abuse

Evidence

A prospective study examining stress as a mediator between corporal punishment and physical abuse, following families over time with assessments of both parenting behavior and stress levels. Found that parental stress significantly moderated the relationship between disciplinary physical contact and abusive physical contact: parents who used corporal punishment and experienced high stress levels were at substantially elevated risk of crossing into abusive conduct, compared to parents using corporal punishment under low stress. The mechanism proposed was inhibitory threshold reduction — stress depletes the cognitive and emotional resources that cause parents to stop short of injury during disciplinary encounters. — , The Rod and the Child, 10379
