Research and evidence

The science of healing. Applied in nature.

3Trees is not a feel-good camp with a therapist on call. It's a clinical program designed from two decades of peer-reviewed research on childhood trauma, neurobiology, and what actually helps young people recover.

The evidence base

Five findings that shape our program.

1

Trauma changes the developing brain

Childhood maltreatment is associated with structural and functional brain changes, particularly in systems that regulate stress, threat detection, and emotion. These changes increase vulnerability to PTSD, depression, and anxiety.

2

Timing matters

The type and timing of trauma shape clinical trajectories and brain aging. Early intervention, during windows of heightened neuroplasticity, leads to better outcomes than delayed treatment.

3

Standard therapy is often not enough

Youth with trauma histories often show reduced responsiveness to weekly therapy alone. They need tailored, multidisciplinary interventions that address mental health and build resilience at the same time.

4

Resilience is possible, but harder after trauma

Resilience factors, like supportive relationships and community belonging, buffer against future stress. But young people who have experienced trauma often have fewer of these protective factors.

5

Connection is the intervention

During sensitive developmental periods, high-quality peer relationships, supportive caregiving, and emotion regulation scaffolding can become embedded in the brain's stress-regulatory systems. Connection is not a nice-to-have. It is the treatment.

Featured publication

A translational model of childhood maltreatment.

In 2026, 3Trees co-founder Dr. Pia Pechtel published an editorial in Clinical Psychology in Europe outlining a Research-Principles-Action framework for childhood trauma. The 3Trees program applies this framework in practice.
