A Study in Resilience: Our Children’s Past Is Not Their Prison
If you are a Plan B parent, you have probably had a version of this moment: you are watching your child struggle—with trust, with relationships, with behavior that seems to come out of nowhere—and a quiet fear settles in. What if the things that happened to them before they came to me have already set the course of their life? What if I am too late? What if they cannot learn resilience?
That fear is understandable, and it comes from a place of deep love. But a significant new study published this month offers evidence-based hope for all of us.
Researchers at UNSW Sydney have completed a 12-year longitudinal study that followed 1,668 Australian adults who had experienced adverse childhood experiences (ACEs). Their finding is both surprising and deeply affirming: childhood trauma does not predetermine a person's future. Two thirds of people who experienced childhood adversity maintained moderate to high mental wellbeing across the entire 12-year study period.
What the Study Actually Found
The UNSW Sydney research team, led by Adjunct Professor Justine Gatt, used data from the TWIN-10 longitudinal study, which followed more than 1,600 healthy adults at four different time points between 2009 and 2024. Participants completed the COMPAS-W Wellbeing Scale—a 26-item tool that measures composure, self-worth, mastery, positivity, achievement, and life satisfaction. At the 10- and 12-year follow-up points, they were also assessed on mental and physical health, behavior, and social functioning.
The researchers measured 17 distinct types of adverse childhood events, including adoption, extreme poverty and neglect, sustained family conflict, life-threatening illness, and domestic violence—the exact kinds of histories that many children in foster and adoptive placements carry with them.
Of the nearly 900 participants who had faced adverse childhood experiences, the study found two distinct wellbeing pathways:
- The Resilient Group: Two thirds of ACE survivors maintained moderate to high mental wellbeing across the entire 12-year period.
- The Risk Group: One third of ACE survivors showed persistently low wellbeing over the same period.
By comparison, more than 85% of participants who had not experienced childhood trauma remained in the higher wellbeing group. So yes, ACEs do have a negative impact—individuals with ACEs were about twice as likely to fall into the low-wellbeing group. But the critical takeaway is that adversity did not lock most people into a difficult life trajectory.
The ACE-Resilient Outcome: What It Looks Like Over Time
What made this study especially compelling were the long-term health outcomes for those in the resilient group—the people who maintained higher wellbeing despite childhood trauma. Over 12 years, this group experienced profound downstream benefits. Compared to low-resilience peers, they were:
- 74% less likely to develop a psychiatric illness
- 70% less likely to become obese
- Significantly less likely to experience migraines, sleep problems, and alcohol misuse
- More likely to report better relationships, greater social support, higher life satisfaction, and more positive coping strategies
These are not small quality-of-life improvements. These are sweeping differences in physical health, mental health, and relational functioning—maintained across more than a decade. And they show up in people who started in the same place as those in the risk group: with a childhood marked by significant adversity.
As Professor Gatt noted in the UNSW press release: "What surprised me most was how people can maintain and rebuild their wellbeing over time, even after early adversity. It shows why investing in wellbeing is just as important as treating distress."
Where This Fits in the Existing Research
To appreciate what this study adds, it helps to understand where it sits in the broader landscape of ACE research.
The original ACE study was groundbreaking in documenting the relationship between childhood adversity and adult health problems. The more ACEs a person experienced, the greater their risk for chronic illness, mental health disorders, and even premature death. That research rightly transformed how we understand child welfare, public health, and trauma-informed care.
But it also unintentionally created a sometimes-bleak narrative: that children who had experienced significant trauma were on a predictable path toward poor outcomes. In communities serving children from foster care, that narrative can quietly shape how adults see the children in their care.
More recent research has complicated that picture with more hopeful evidence. A 2019 study from Wales examining children adopted from foster care found that parental warmth was a significant moderating factor—children with higher ACEs who had adoptive parents who expressed high warmth showed markedly better emotional outcomes than children whose parents showed lower warmth. Similarly, research on foster parents found that foster parent resilience was more strongly associated with positive parenting outcomes than the foster parent's own ACE history—suggesting that resilience is teachable and transferable.
The new UNSW study advances this conversation significantly by tracking wellbeing—not just the absence of disorder, but the positive presence of mental health—over 12 years. That distinction matters enormously. Most ACE research has focused on pathology: what goes wrong. This study asks a different question: what does going right look like, and can it be sustained?
The answer, it turns out, is yes—for most people, even those with significant trauma histories.
What This Means for You as a Plan B Parent
Plan B parents occupy a unique and demanding position. You are parenting children whose early experiences—before they ever came to you—have shaped their nervous systems, their attachment patterns, their sense of safety, and their expectations of adults. You often don't know the full extent of what they have been through. And you are asked to help them heal without always having a roadmap.
This study speaks directly to your role, in several important ways.
Your Presence Is an Active Ingredient
The UNSW research team notes that among the characteristics observed in their resilient group, people had stronger relationships, more social support, and better coping strategies. Crucially, earlier work by the same research group found that resilient individuals tended to have healthier ways of dealing with stress, better emotion regulation, and personality traits linked to better social connection. These are not innate, fixed traits. They are skills—and they develop in relationships.
This aligns with what Harvard's Center on the Developing Child has documented for years: "the single most common factor for children who develop resilience is at least one stable and committed relationship with a supportive parent, caregiver, or other adult." You are that relationship for your child. Not a perfect relationship—a present, committed one.
Wellbeing Is a Skill You Can Help Build
One of the most important reframes in the UNSW study is that we should treat mental health as a positive capacity to be built, not simply a crisis to be managed. Professor Gatt was explicit: "Mental health should be proactively treated as a positive capacity that can be built, not just a crisis to be managed when things fall apart."
For Plan B parents, this means that every time you:
- Help your child name and manage a difficult emotion
- Model healthy coping when you are stressed
- Create a predictable routine that signals safety
- Celebrate effort and persistence over perfection
- Stay regulated yourself when they are dysregulated
…you are doing the work of building mental wellbeing capacity. You are not just managing behavior. You are actively contributing to your child's long-term trajectory.
The Two-Thirds Are Not an Accident
It would be easy to look at the UNSW finding—that two thirds of ACE survivors maintained good wellbeing—and assume those people were simply lucky. But the researchers are pointing in a different direction. The resilient group didn't just stumble into good outcomes. They were more likely to exercise regularly, eat well, maintain meaningful relationships, and engage in activities they enjoyed. They had developed stronger emotion regulation and coping skills.
None of those things happen in isolation. They are built—often, in childhood—in homes where adults invest in a child's capacity to cope, connect, and thrive. You may be the first adult in your child's life who has done that work with them. That matters more than you know.
What to Do With This Research Right Now
Research is only useful if it changes what we do. Here are some practical takeaways from the UNSW findings for your daily life as a Plan B parent.
Reframe Your Goal
If your goal has been to prevent the worst outcomes—to keep your child from developing mental illness, from struggling with substances, from repeating painful patterns—you can broaden that goal. The research suggests that actively building wellbeing (not just reducing harm) is what produces the most durable results. Shift from "keep them from falling" to "help them learn to fly."
Track the Positive
The COMPAS-W Wellbeing Scale that the UNSW researchers used measures composure, own-worth, mastery, positivity, achievement, and life satisfaction. These same domains are trackable in a child. You don't need a clinical tool. You can simply pay attention: Is your child developing a stronger sense of self? Are they better able to recover from setbacks than they were six months ago? Are they starting to trust their own judgment? Noticing growth—and naming it to your child—builds the very wellbeing this research points to.
Invest in Your Own Resilience
The study I mentioned above about foster parents found that foster parent resilience was more predictive of good parenting outcomes than whether the foster parent had their own ACE history. Your resilience is contagious. When you take your own mental health seriously—seeking support, practicing self-regulation, building your own coping strategies—you are not being selfish. You are modeling exactly what the UNSW resilient group was doing.
Don't Wait for a Crisis
The UNSW researchers argue for a prevention-focused approach that builds wellbeing proactively—not just responds to problems reactively. This maps well onto trauma-informed parenting practice. Therapeutic support, when used as a maintenance tool rather than only a crisis intervention, allows children to build emotional vocabulary and coping skills during calm periods, so those tools are available when things get hard. If your child is in therapy, encourage that work even during good patches. If they are not, and you have ongoing concerns, consider getting support now rather than waiting for a breaking point.
A Word About the One Third
It would be incomplete to celebrate this research without acknowledging the one third of ACE survivors who did not maintain good wellbeing in the study. Their struggle is real and it matters. For some children, the volume of adversity, the absence of stable relationships, and the lack of access to support creates compounding difficulties that require intensive, sustained intervention.
If you are parenting a child who is in that harder place—where progress is slow, where behaviors are intense, where the work is genuinely exhausting—this research does not dismiss your experience. It simply says that the trajectory is not fixed. Researchers are currently working to understand more deeply what differentiates the resilient group from the risk group, with the goal of developing targeted interventions. That research is coming. And in the meantime, staying in the relationship, continuing to offer the consistent, warm presence that matters most, remains the most evidence-based thing you can do.
The Bottom Line
Childhood trauma is real. Adverse childhood experiences have measurable, lasting impacts on health and wellbeing. The original ACE research documented that clearly, and it stands. But the UNSW study adds a critical chapter to that story: most people who experience childhood adversity build and maintain strong wellbeing across their adult lives. And the conditions that support that outcome—stable relationships, positive coping, emotional regulation, and a home that builds capacity—are things you, as a Plan B parent, are uniquely positioned to provide.
Professor Gatt said it plainly: "Childhood adversity can be traumatic, but it doesn't have to determine a person's whole life."
Neither does it determine yours as a parent. The hard days, the setbacks, the moments when you wonder if any of this is working—they are part of a longer story. And the evidence says that story can end well.
