TRP-PR Research & Study Results

Real outcome data from people who serve. All data was collected by Healing the Hero, a 501(c)(3) nonprofit, using the Trauma Resiliency Protocol-Performance Recovery (TRP-PR). Scores are group averages before and after TRP-PR.

Published research: A Pilot Study of a Trauma Resiliency Protocol for Law Enforcement Officers With Posttraumatic Stress Disorder Symptoms — Maguire et al., Arizona State University, Journal of Occupational and Environmental Medicine (2024), 128 law enforcement officers.

Methodology

How results are measured

PCL-5 — PTSD symptoms, 0–80. Screening range 31–80.

GAD-7 — Anxiety, 0–21. Moderate 10–14 · Severe 15–21.

PHQ-9 — Depression, 0–27. Moderate 10–14 · Moderately severe 15–19 · Severe 20–27.

Lower scores mean fewer reported symptoms. These are self-report screening tools, not a diagnosis. Before-and-after observations do not by themselves establish causation.

Longevity

Long-term follow-up

Participants in the ASU qEEG study (57) were re-measured about 11 months after their post scores, on average. Their gains held.

Measure	Pre	Post	Follow-up
PTSD (PCL-5)	47.6	0.5	0.1
Depression (PHQ-9)	14.6	0.4	0.0
Anxiety (GAD-7)	13.2	0.2	0.0

Ongoing research

Current & planned studies

Arizona State University

Primary investigator: Dr. Maguire

PCL-5, GAD-7, PHQ-9 and ACEs questionnaires, a non-invasive qEEG brain scan, 1–5 doses of TRP-PR, then retesting and a second qEEG scan.

San Diego State University (planned)

Primary investigator: Dr. Tereza Trejbalova

A randomized controlled trial comparing human and AI delivery of TRP with corrections officers. IRB oversight planned through SDSU.
