Spanking and Yelling: What the Research Actually Shows

Four "no"s, a kitchen that looks like a small storm came through it, and a caregiver who is finished. This is the moment most advice about discipline is really written about, and it is usually the moment where a voice gets loud or a hand moves.

The honest answer has two halves. In the moment, a smack or a shout often stops the behavior in front of you, which is exactly why it feels like it works. Over months and years, the research points somewhere else. This guide covers what the pediatric guidance and the larger studies say, what they cannot settle, two myths that keep the cycle going, and what a caregiver can try on an ordinary Tuesday. It closes with one book chapter to keep nearby.

This episode is general education, not medical advice.

In a 2018 policy statement in the journal Pediatrics, the American Academy of Pediatrics wrote that aversive disciplinary strategies — all forms of corporal punishment, and yelling at or shaming children — are minimally effective in the short term and not effective in the long term. The academy linked corporal punishment to an increased risk of negative behavioral, cognitive, psychosocial, and emotional outcomes for children. 1

The clearest single summary of the underlying studies is a 2016 meta-analysis by Elizabeth Gershoff and Andrew Grogan-Kaylor in the Journal of Family Psychology. They pooled 111 effect sizes covering more than 160,000 children. Thirteen of the 17 average effects they calculated were significantly different from zero, and every one of those pointed the same way: a higher risk of worse outcomes, including more aggression and more behavior problems.

The authors also tested whether that pattern was an artifact of weak study design. It did not shrink when stronger designs were compared with weaker ones, and the average association for spanking looked similar in size to the one they found for more severe physical abuse. 2

How common is spanking? A national survey of 9,000 caregivers in the United States, reported in 2024 in the journal Pediatric Reports, found that about one in six said they had spanked their child in the past week. Those parents also reported seeking out more kinds of support than parents who did not spank, which the authors read as an opening: the families most likely to be helped are already looking for help. 3

Two newer studies add detail. A 2026 cohort study of 4,610 adolescents in Portugal found that when both parents used corporal punishment or psychological aggression, the association with later substance use and depressive symptoms was larger than each parent's contribution added together on its own. 4 A 2026 longitudinal study of 663 children in Ghana found that repeated harsh discipline at home predicted lower academic skills over three years, while harsh discipline at school did not reach statistical significance, and neither predicted executive function. 5

Families are not randomly assigned to discipline strategies. Most of this research follows families as they already are, so the families who spank may also differ in stress, income, sleep, and available support. A statistical association cannot sort all of that out, and no study here can tell you what happened inside one particular family.

One illustration of how tangled this gets comes from a 2026 study in Family Process. Researchers followed 604 families in Singapore, where physical discipline is common, measuring it alongside children's behavior problems at three points between ages four and ten and a half. 6

Between families, the pattern matched the wider literature: the families who used more physical discipline had children with more behavior problems. Within families, the picture was more complicated. When a mother used more physical discipline than her own usual level at age four and a half, that predicted slightly lower behavior problems at age seven. The authors do not read that finding as a case for spanking; they point to how complex these patterns are and note that most of the evidence still runs the other way. A single study can hold more than one truth.

There is also a live disagreement among researchers. In 2025, a group of researchers argued in the Journal of the Canadian Academy of Child and Adolescent Psychiatry that the causal evidence used to justify spanking bans is weaker than it is usually presented, and other researchers answered them in the same journal. 7 The American Academy of Pediatrics and most research organizations read the same body of studies as sufficient to advise against physical punishment.

Myth one: it works, because the behavior stops. It often does stop, right then. But stopping a behavior is not the same as learning what to do instead, and the studies that follow children for years keep finding the same pattern. Immediate relief for the adult is a different result from a child who is building a way to handle the next hard moment.

Myth two: yelling is not physical, so it does not really count. In a 2014 study in the journal Child Development, Ming-Te Wang and Sarah Kenny followed 976 two-parent families through the year their children turned thirteen. Parents who shouted, swore, or humiliated their teenager saw conduct problems and depressive symptoms rise over the following year. The reverse also held: as the teenager's behavior got worse, the yelling increased. It ran in both directions. Parental warmth did not cancel it out. 8

The pediatric guidance points toward teaching and toward support, not toward harsher consequences. What that looks like in a real kitchen is usually smaller than it sounds.

Say what you want, not what you want stopped. "Shoes on, then we go" is something a young child can act on. "Stop messing around" is not.

Decide the consequence before the moment, and keep it short: a brief quiet time, a break for both of you, or a privilege that ends today. A consequence that lasts a week mostly reminds everyone how angry they were.

Watch your own body. When your chest tightens, that is the signal to change the scene rather than win it. Step into the doorway. Run cold water over your hands. Ask another adult to take over for ten minutes if one is there.

Repair afterward. A child who has watched you lose your temper learns something from what happens next, and the repair can be short: "I shouted. That was mine to fix. Here is what we do now."

Getting help changes what happens at home. A 2026 randomized trial reported in Children and Youth Services Review offered brief parenting sessions to 720 caregivers in clinics for women, infants, and children. Parents who received them described more patience and better communication with their child, and the parents in one of the two programs described stopping physical punishment. 9

If you are worried about your own anger, or about anyone's safety at home, say it out loud to your child's doctor or to a family support line. That is not an overreaction.

For a practical companion, read the chapter "How to Stop Yelling at Your Child" in Dr. Laura Markham's Peaceful Parent, Happy Kids. It sits in the book's opening section on regulating yourself, before the sections on connection and coaching. 1011 Later in the book Markham takes up spanking and time-outs directly, in the section called "Setting Limits with Empathy". The book is built on clinical experience rather than research trials, so read it as practical guidance alongside the studies, not as a substitute for them.

Bring one thing into this week: pick your own signal for when the heat is rising, and decide now what you will do when you feel it. The research is about patterns across months and years. One bad evening is not a verdict on your family, and the next moment is still yours to shape.

This episode is general education, not medical advice. Families differ, and a caregiver who needs more support than a podcast can offer deserves it without shame.
