Is this trial a fit for you?

Likely a good fit

Ideal candidates are families in Sweden with children aged 8–16 who have trouble controlling anger or meet criteria for oppositional defiant disorder or aggressive conduct, and whose parents can read Swedish.

Probably not a fit

Children with severe depression, active suicidality, bipolar disorder, psychosis, severe autism (level 2–3), intellectual disability, ongoing criminal behavior requiring other interventions, or those already in concurrent psychological treatment for the same condition are unlikely to benefit from this program.

What this trial studies

The program begins with a brief internet-based parenting support course ('Step 1') for families of children aged 8–16 who show defiant or aggressive behaviors. Families whose problems persist are offered Step 2, which may be CBT delivered with virtual-reality support for either the parent or the child, or standard clinic-based interventions plus continued online support, with the option to later choose CBT-VR. Outcomes include changes in child aggressive and oppositional behaviors, treatment engagement, and feasibility of using a stepped approach. The project is coordinated by Karolinska Institutet and Region Stockholm and requires participants to engage with materials in Swedish.

Why it matters

Potential benefit: If successful, the model could reduce children's aggressive and defiant behaviors by matching families to the least intensive effective intervention and offering VR-enhanced CBT when needed.

How similar studies have gone: Parenting programs and CBT have established evidence for reducing child behavior problems, while virtual-reality–assisted CBT is a newer approach with promising but limited clinical data.
