Discipline without hitting or humiliation
Behavior and emotional problems are more common among children exposed to physical punishment or harsh verbal discipline. This is not a prediction about an individual child.
Use discipline without hitting your child or calling them stupid or lazy.
The spanking meta-analysis found an overall adverse association of d = 0.33, not a percentage change.
Why consider it?
The standardized effect summarizes varied child outcomes. Most evidence is observational or retrospective, and the book cites competing analyses finding smaller associations after accounting for earlier behavior. Causality and effect size are debated. Harsh verbal discipline was separately associated with later problems. The action is a parenting precaution, not a treatment or legal claim.
