In Stockholm, 137 parents of children with ADHD, autism, and other disabilities stepped into a group therapy room and discovered something that changed how they moved through their days: the ability to sit with stress without letting it control them. The Navigator ACT program, a group-based intervention grounded in Acceptance and Commitment Therapy, delivered measurable shifts in how these parents experienced their lives, according to a randomized controlled trial published in Autism Research by researchers at Karolinska Institutet.
Parenting a child with a disability—whether ADHD, autism, intellectual disability, motor impairments, or acquired brain injuries—often means carrying relentless, long-term demands. Many of the children in this study had multiple diagnoses, layering complexity upon complexity. The stress that accompanies this reality is not theoretical; it is lived, daily, and often invisible to those outside the family. The question researchers wanted to answer was straightforward but important: could a structured group program actually help these parents find steadier ground?
Half of the 137 parents participated in Navigator ACT, a program delivered by habilitation staff who had received specific training, though many had limited prior experience with ACT itself. The other half received standard care through habilitation services. What emerged from the comparison was striking. Parents in the Navigator ACT group showed the clearest improvements in psychological flexibility—the ability to face stress and difficult thoughts and emotions without getting stuck in them, while still choosing how to act in everyday life. These gains held firm at follow-up assessments months after the program ended. They also reported lower levels of parenting stress overall compared with the control group.
"The intervention made it easier to be the parent you want to be," says Tiina Holmberg Bergman, the study's first author and a researcher at Karolinska Institutet's Center of Neurodevelopmental Disorders. The statement, simple as it sounds, captures something profound about what psychological flexibility actually means in practice. The stressors didn't disappear—the children still had disabilities, the demands were still there—but parents became less reactive in challenging situations. They found ways to accept their circumstances while still moving toward the life they valued.
What struck participants most, beyond the measurable shifts, was the experience of connection. In interviews, many emphasized how meaningful it was simply to share experiences with other parents in similar situations. Parents described how the program helped them turn what felt like a negative downward spiral into something more positive. They learned concrete skills—tools drawn from ACT's framework—that they continued using in daily life long after the formal program ended.
The fact that Navigator ACT worked when delivered through routine clinical practice, by staff without extensive ACT backgrounds, matters. This wasn't a study conducted in a research bubble with ideal conditions and specialist trainers. It was implemented in the real world, within Region Stockholm's habilitation services, and it still moved the needle.
For parents navigating the unrelenting demands of raising a child with disabilities, Navigator ACT offers something increasingly rare: evidence-based support specifically designed for them, delivered in their communities, by people they already know. The results suggest that when parents gain psychological flexibility, they don't just feel better—they live better, more meaningfully, despite the challenges that remain.
