The Phoenix Trauma Response Model (Ptrm): An Integrative And Innovative Approach To Trauma Recovery And Growth, Latesha S. Holloman, Lauren B. Robins, Tammie Willis, Courtney V. Morris

Journal of Human Services Scholarship and Interprofessional Collaboration

Trauma is increasingly understood as a developmentally consequential experience that shapes identity, regulation, and relational functioning across the lifespan. Although trauma-informed care, resilience theory, posttraumatic growth, and narrative approaches have expanded understanding of recovery, few frameworks articulate a structured developmental progression that integrates prevention, intervention, and intergenerational transformation within a unified model. The Phoenix Trauma Response Model (PTRM) addresses this gap by introducing a cyclical, phase-based framework organized around four interrelated processes: Recognition, Reframing, Reclamation, and Replication of Strength. Central to the model is the construct of conversion potential, defined as the structured capacity to translate distress into purposeful …
