Grandparents Hold an Unexpected Key to Kids' Mental Health — The Science Is Clear

TL;DR

• Over 40% of US teenagers report ongoing feelings of sadness or hopelessness — a crisis the Surgeon General has called a "continuing emergency."
• Clinical psychologist Dr Kenneth Barish, drawing on 40 years of clinical experience and neuroscience research, argues that grandparents may be one of the most powerful — and most overlooked — solutions.
• His new book, The Art and Science of Parenting and Grandparenting, published through Taylor & Francis, articulates what he calls "molecules of emotional health" — small moments of attention, listening, and encouragement that strengthen a child's emotional immune system.
• The core thesis: children need purpose, supportive relationships, and meaningful conversations — not just pressure to achieve.
• Grandparents can provide exactly this, at a moment when extended family involvement has declined sharply.

What Happened

On June 13, 2026, ScienceDaily published findings from a new book by Dr Kenneth Barish, Clinical Professor of Psychology at Weill Cornell Medicine and Fellow of the American Psychological Association.

The headline finding: grandparents may be one of the most powerful interventions for the youth mental health crisis — and families are systematically underusing them.

Barish's argument is built on three pillars:

• 40 years of clinical practice working with children and families.
• Neuroscience research on emotional development and resilience.
• Educational program data on what actually improves child outcomes.

The book arrives at a specific cultural diagnosis: "Over several decades, America has increasingly become a society of I, not We. In many families and communities, preoccupation with individual achievement has eroded the values of kindness and caring in the lives of our children."

Barish does not mince words about what this means: Individual achievement alone is a fragile source of motivation and effort, with a high cost in anxiety and stress.

What It Actually Means

This is not a "call your grandparents" sentiment piece. It is a structural argument about what children actually need versus what parents are conditioned to provide.

The dominant parenting paradigm — particularly in affluent and aspirational communities — treats childhood as a performance pipeline: academic scores, extracurricular achievements, selective school admissions, résumé building. Barish's argument is that this pipeline actively damages children by starving them of what they actually require: meaningful relationships, a sense of purpose beyond themselves, and adults who listen rather than evaluate.

Grandparents are uniquely positioned to provide these things because they are largely outside the performance pipeline. A grandparent does not care about your NAPLAN score. A grandparent is not evaluating your university application. A grandparent can listen without agenda.

Barish describes this as providing "molecules of emotional health" — small, repeated interactions that build what he calls a child's "emotional immune system." The metaphor is precise: just as the immune system requires repeated, low-grade exposure to pathogens to build strength, a child's emotional resilience is built through thousands of small moments of feeling heard, understood, and unconditionally valued.

The research Barish cites — particularly the work of psychologist Jane Piliavin — shows that helping others is associated with higher self-esteem, lower depression rates, reduced school dropout, improved immune function, and longer life expectancy. These effects are not peripheral. They are comparable in magnitude to many medical interventions.

The Criticism Problem

One of Barish's most arresting findings from clinical practice is also the most practically useful: the most common problem he sees in families is not too much praise — it's too much criticism.

Well-intentioned parents and grandparents, he argues, consistently underestimate the damage of frequent criticism. "Criticism does not motivate children to work harder. Instead, frequent criticism breeds resentment and defiance, and undermines children's initiative and effort."

This is not a call for permissive parenting. It is an evidence-based calibration: criticism is metabolised differently by developing brains than praise is. The ratio matters. And family members who see themselves as lovingly "tough" or "honest" may be damaging the very resilience they hope to build.

What This Means for You

For parents of school-age children:

• Make the invitation explicit. Grandparents often hesitate to step in because they don't want to overstep. Tell them: You are needed. Not for homework help. For presence.
• Reclaim the weekly call or visit. Barish's "molecules of emotional health" require repetition. A once-a-year holiday visit is not enough. A 15-minute weekly video call — with no agenda, no progress report — is.
• Create opportunities for purpose, not performance. Volunteering as a family. Conversations about kindness and empathy. These are not "soft" activities. They are evidence-based interventions for building emotional resilience.

For grandparents (or grandparents-in-waiting):

• Listen more than you advise. Your greatest asset is not your life experience — it is your willingness to listen without immediately solving.
• Praise effort, not intelligence. Drawing on Carol Dweck's growth mindset research, Barish advises: "Praise effort, not intelligence or talent. Praise learning, not grades."
• Be a reset, not a reinforcement. If the child is under pressure at school and at home, you can be the place where pressure is absent. This is not undermining parents. It is providing a necessary counterbalance.

For everyone:

• The "I to We" shift starts at home. Barish's diagnosis of a hyper-individualised culture is not abstract. It plays out in how we talk to children about what matters. If every conversation is about achievement, children learn that they are valued for what they produce, not who they are. Grandparents can model the alternative — simply by existing outside that framework.

Uncertainty Ledger

• The research cited is largely correlational. Causal claims about grandparent involvement improving mental health outcomes are inferred from broader developmental psychology literature, not from randomised controlled trials of grandparent intervention.
• Barish's clinical experience, while extensive, represents a specific population (largely affluent, treatment-seeking families in the northeastern US). The generalisability to other cultural contexts — including Australian families — is reasonable but unproven.
• The book has just been released. Independent reviews and replication studies are not yet available.

Bottom Line

The youth mental health crisis will not be solved by more therapy, more medication, or more screening. It will be solved — if it is solved — by rebuilding the relational infrastructure that children need to thrive: adults who listen without judging, who offer presence without agenda, and who remind children that they matter for who they are, not what they achieve. Grandparents are the most underutilised resource in that rebuilding. Call them.

What This Means for You

Recommendations addressed to parents, grandparents, and extended family of school-age children.

For parents:

• Invite grandparents in. Explicitly. Many are waiting for permission.
• A 15-minute weekly video call with no agenda beats a holiday visit once a year.
• If every conversation with your child is about achievement, they learn they are valued for output, not for who they are.

For grandparents:

• Your greatest asset is your willingness to listen without immediately solving.
• Praise effort, not grades. Praise learning, not talent.
• Be the place where pressure is absent. This is not undermining parents — it is providing a necessary counterbalance.

For everyone:

• Volunteering as a family and having explicit conversations about kindness and empathy are evidence-based interventions for building emotional resilience. Treat them with the same seriousness as homework.
