THP: Trauma Healing Process

Proven results in clearing symptoms of post-traumatic stress

Impact at a Glance: Arizona State University Study

  • 128 law enforcement officers treated
  • 100% reduced PTSD symptoms
  • 43.4 → 7.3 average PTSD score drop
  • 83.6% → 19.5% no longer met PTSD criteria
  • 2 sessions average treatment length
  • Significant reductions in anxiety and depression
  • 0 trauma retelling required

What is THP?

A non-trauma-based, emotion-focused protocol delivered through one-on-one telehealth sessions.

  • Participants do not relive or recount traumatic events.
  • Sessions last 15 to 90 minutes, typically 1 to 4 total.

How It Works

  • Builds rapport and emotional safety
  • Uses guided imagery from a third-person perspective
  • Targets emotional responses, not traumatic memories
  • Helps restore parasympathetic regulation disrupted by trauma

Why It Matters

First responders and veterans face trauma at levels far above the general population. THP offers a fast, safe, effective path to relief, without exposure therapy.

Scientific Validation

A 2024 peer-reviewed pilot study found THP produced a "huge" effect size (Cohen's d > 2), a level rarely seen in psychological interventions.

The Bottom Line

22ZERO's THP is one of the most promising, accessible, and effective tools for reducing PTSD symptoms in first responders.

Together, we are clearing the symptoms of PTS and saving lives.

ARE YOUR PROCESSES EVIDENCE BASED?

Evidence Based Practices (EBP) can take years of research for a new technique to become an EBP. Dr. Arnell started the evidence based practice research in 2022 searching for independent research outside of 22ZERO. Dr. Arnell contacted Arizona State University and ASU agreed to do the independent study for 22ZERO. The first study was published in 2024. As of October 2026, two more ASU studies have been completed and accepted for publication in two journals, and one more study is in the peer review phase.

Dr. Arnell co-authored one of these studies. While proving Evidence Based Practices is important to Dr. Arnell, the process can take time; which is why Dr. Arnell started the process to prove EBP in 2022. 22ZERO is grateful to Arizona State University for supporting the research journey.
