Acceptance and Commitment Therapy (ACT) for Trauma: Insights from Russ Harris

The Soul Tree Therapy team recently had the privilege of attending a workshop led by Russ Harris, a leading expert in Acceptance and Commitment Therapy (ACT) and author of The Happiness Trap. The workshop offered invaluable insights into how ACT can be effectively applied to trauma recovery, emphasizing healing through acceptance and committed living rather than traditional trauma exposure methods.

Trauma often leaves deep emotional wounds that impact how individuals experience life, relationships, and their sense of self. Many trauma survivors develop avoidance patterns to escape painful memories and emotions, which can unfortunately reinforce suffering and limit growth. Russ Harris’s approach with ACT challenges this cycle by encouraging acceptance—welcoming difficult thoughts and feelings rather than struggling against them. This shift in perspective reduces the emotional burden and prevents trauma-related pain from controlling behavior and decisions.

A fundamental ACT process Harris highlights is cognitive defusion, which teaches clients to create distance from trauma-related thoughts by seeing them as mere words or mental events rather than literal truths. This reduces their power and allows individuals to engage more fully with life. Mindfulness and present-moment awareness are also central components in Harris’s trauma-sensitive ACT. These practices help clients safely reconnect to the here-and-now instead of being trapped by the past or overwhelmed by worries about the future.

Another vital element is values clarification. Trauma can obscure what truly matters, leaving survivors feeling lost and unmoored. Harris stresses helping clients rediscover and articulate their core values, which then serve as a compass for healing and growth. This process enables trauma survivors to reclaim meaning and purpose beyond their suffering.

ACT also emphasizes committed action—taking meaningful steps forward in life, even when pain remains present. Harris offers trauma-informed ACT exercises that avoid forcing trauma exposure, making therapy more accessible and less retraumatizing. Clinicians trained in his methods report higher client engagement, fewer dropouts, and improved coping skills for those with PTSD and complex trauma.

Russ Harris’s work beautifully illustrates that trauma recovery isn’t about erasing painful memories but about cultivating psychological flexibility—the ability to adapt to difficult internal experiences and external challenges. ACT provides trauma survivors with practical tools to accept their experiences, defuse from unhelpful thoughts, stay grounded in the present, clarify what truly matters, and commit to actions aligned with their values. This approach fosters resilience and opens the door to a rich, meaningful life alongside trauma.

For clinicians and trauma survivors alike, exploring Russ Harris’s trauma-informed ACT resources can offer new pathways toward healing, empowerment, and hope.
