Preventing adverse childhood experiences (ACEs) requires action at every level, from how parents interact with their children at home to the policies that shape whether families have enough money, time, and support to function well. About 64% of U.S. adults report experiencing at least one ACE during childhood, and 17% report four or more. The annual economic burden tied to ACE-related health conditions in adults reaches an estimated $14.1 trillion, counting both medical spending and lost healthy years of life. These numbers make clear that ACEs are not rare individual misfortunes but a widespread public health problem, and one that responds to prevention.
What Counts as an ACE
ACEs are potentially traumatic events that happen before age 18. They include abuse (physical, emotional, or sexual), neglect (physical or emotional), and household dysfunction like living with someone who misuses substances, witnessing domestic violence, parental separation, a household member’s mental illness, or a household member going to prison. The original ACE categories were defined by a landmark CDC-Kaiser study, and they remain the standard framework. The more ACEs a child accumulates, the higher their risk for chronic disease, mental health conditions, and substance use problems later in life.
What Parents and Caregivers Can Do
The single most powerful protective factor against ACEs is a safe, stable, nurturing relationship with at least one adult. For parents, this starts with everyday interactions: talking openly with your child about their emotions, helping them learn to recognize and manage what they feel, and looking for regular opportunities to offer genuine praise. These aren’t soft suggestions. Consistent emotional attunement builds the neural pathways children need to handle stress throughout their lives.
Watch for signs of distress. Anger, withdrawal, changes in school performance, disrupted sleep, or shifts in eating patterns all signal that something may be wrong. Acting on those signals early, rather than waiting for a crisis, can prevent a difficult period from becoming a lasting source of harm.
Parenting skill training programs offer structured ways to strengthen your relationship with your child. These evidence-based programs teach techniques for positive discipline, communication, and emotional coaching. Many are available free or at low cost through community organizations, pediatric clinics, and school districts. If you’re navigating your own history of childhood adversity, these programs can be especially valuable because they give you concrete tools to parent differently than you were parented.
Breaking the Cycle of Substance Misuse
Parental substance use is one of the most common ACEs, and it fuels a cycle: adults who experienced ACEs are more likely to develop substance use disorders, which in turn create ACEs for their own children. Family-centered substance use treatment is one evidence-based strategy for interrupting this pattern. Unlike traditional treatment that focuses solely on the individual, family-centered programs treat the parent while simultaneously strengthening parenting skills, addressing the children’s needs, and improving family functioning as a whole.
The outcomes are meaningful. Family-centered treatment is linked to higher rates of family reunification, reduced potential for child abuse, improved parental mental and physical health, and better psychosocial functioning for children. As one outreach coordinator put it, “You’re kind of breaking that cycle if you’re helping the whole family.” For pregnant and postpartum parents, these programs offer a critical window to disrupt intergenerational transmission of trauma before it takes hold.
How Communities Prevent ACEs
Prevention doesn’t rest on parents alone. Community organizations, including faith-based groups, youth-serving organizations, and local nonprofits, play a central role by expanding the number of safe, supportive adults in a child’s life. Mentoring programs and after-school activities connect young people with positive role models and give them chances to build skills and confidence outside the home. If you’re looking for a way to contribute, volunteering as a mentor or simply offering to babysit for a stressed parent in your circle can make a real difference.
Communities also prevent ACEs by improving access to quality childcare, preschool programs, and in-home support for new parents. Licensed, accredited childcare settings provide safe environments while freeing parents to work and reducing the financial and emotional pressure that contributes to maltreatment. Programs that teach youth healthy relationship skills address another root cause by helping young people recognize and avoid patterns of violence before they carry those patterns into adulthood and parenthood.
When ACEs do occur, community-based services like crisis intervention, therapy, and family-centered treatment help reduce the lasting harm and prevent further adversity from accumulating.
The Role of Schools
Schools are where children spend most of their waking hours, which makes them a natural setting for both prevention and early intervention. Trauma-informed schools train all staff to recognize the signs of trauma, respond with support rather than punishment, and avoid practices that might retraumatize students. This doesn’t mean turning teachers into therapists. It means creating a school culture built on safety, trust, and predictability.
Social and emotional learning (SEL) curricula teach children how to understand and manage emotions, set goals, show empathy, and make responsible decisions. These are the same self-regulation skills that serve as protective factors against the effects of adversity. Some schools go further by embedding licensed clinical social workers who run small group sessions on topics like anger management, mindfulness, grief, and healthy coping skills. Others employ intervention specialists and mentors who work specifically with high-risk populations, such as students in foster care.
Restorative justice practices offer another layer of prevention. Instead of suspending or expelling students for behavioral problems, which often stem from trauma, schools use mediation and de-escalation circles to keep kids in the classroom and connected to their community. Removing a child from school typically worsens their trajectory. Keeping them engaged and supported does the opposite.
Economic Supports That Protect Families
Financial hardship damages parents’ mental health, strains family relationships, and worsens children’s health and educational outcomes. Addressing poverty directly is one of the most effective upstream strategies for preventing ACEs. Several policy approaches have strong evidence behind them.
- Tax credits and income supports: Expanding access to the Earned Income Tax Credit (EITC), nutrition assistance programs, and childcare subsidies puts money in families’ pockets when they need it most. Multiple states have focused on connecting low-income families and communities of color with benefits they’re already eligible for but haven’t accessed.
- Paid family leave: Policies that allow parents time off for caregiving without losing income reduce stress during the most vulnerable periods of a child’s early development.
- Flexible and consistent work schedules: Unpredictable scheduling makes it nearly impossible for parents to arrange stable childcare or maintain routines. Policies requiring consistent schedules help families plan their lives.
- Subsidized childcare: The cost of childcare pushes many families into impossible choices. Reducing that burden frees parents from the financial strain that contributes to household dysfunction.
States that have implemented these strategies have also shifted their public education campaigns from simply raising awareness to actively connecting families with resources and asking them what barriers they face. That shift matters. Telling families help exists is less useful than helping them walk through the door.
Building Positive Childhood Experiences
Prevention isn’t only about stopping bad things from happening. Research increasingly shows that actively building positive childhood experiences (PCEs) provides a buffer against adversity, even for children who do experience some ACEs. Five domains of positive experience are consistently linked to better adult health outcomes: supportive peer relationships and a healthy school climate, neighborhood safety, neighborhood support, and nurturing relationships with both maternal and paternal figures.
This means that a child who grows up in a safe neighborhood where adults look out for one another, who has at least one warm and consistent relationship with a parent or caregiver, and who feels connected and supported at school has meaningfully better odds of long-term health, even if other parts of their childhood are difficult. Prevention works on both sides of the equation: reducing harm and increasing the experiences that help children thrive.
What Trauma-Informed Systems Look Like
Beyond individual families and communities, the systems children interact with, including healthcare, education, social services, and juvenile justice, can either prevent ACEs or inadvertently make them worse. A trauma-informed system operates on several core principles: physical and psychological safety for everyone involved, transparency in decision-making, collaboration that levels power differences between staff and the people they serve, peer support that draws on lived experience, and a commitment to empowering individuals rather than controlling them.
In practice, this looks like a pediatric clinic that screens for family stressors without judgment and connects parents to resources, a child welfare system that prioritizes keeping families together with support rather than defaulting to separation, or a school that responds to a child’s outburst by asking “what happened to you?” instead of “what’s wrong with you?” These shifts in approach don’t require massive budgets. They require training, institutional commitment, and a willingness to see children’s behavior through the lens of their experiences.
