Phase-oriented treatment stands as one of the most consequential organizational frameworks in the depth-psychological treatment of complex trauma and dissociative disorders, representing what van der Hart, Steele, and their collaborators describe as the current standard of care for survivors of chronic traumatization. The model structures therapeutic work into three successive yet recursively linked phases: stabilization and symptom reduction; treatment of traumatic memories; and personality integration with rehabilitation toward normal life. Crucially, the corpus insists that these phases are not linear but spiral — clients cycle between them as mental efficiency increases, as newly integrated material permits approach to previously intolerable dissociated content, and as relational or somatic destabilization demands return to earlier stabilizing work. Ogden's sensorimotor tradition operationalizes the three phases through somatic resources, memory processing, and relational repair, explicitly framing the model as flexible and client-directed rather than protocol-rigid. Courtois emphasizes the field's ongoing obligation to subject phase-oriented principles to systematic empirical scrutiny, particularly regarding complex dissociative presentations. A productive tension pervades the corpus: between the urgency of trauma memory resolution and the primacy of stabilization, between the sequential logic of the model and the lived non-linearity of traumatic recovery. The framework's enduring authority rests on its capacity to hold this tension without collapsing it.

approaches for complex PTSD and dissociative disorders are typically phase-oriented, are considered the current standard of care, and include the following phases: (1) stabilization and symptom reduction; (2) treatment of traumatic memories; and (3) personality integration and rehabilitation.
Van der Hart establishes phase-oriented treatment as the authoritative standard of care for complex PTSD and dissociative disorders, specifying its three canonical phases while noting their flexible, recursive rather than linear application.
Hart, Onno van der, The Haunted Self Structural Dissociation and the Treatmentthesis
Phase 1 focuses on developing resources to regulate arousal and increase self esteem and competency, Phase 2 on addressing memories, and Phase 3 on exploring relationships and moving on from the past.
Ogden articulates the sensorimotor psychotherapy adaptation of the three-phase model, specifying distinct goals for each phase while emphasizing that their application should be tailored to each client's immediate and long-term therapeutic needs.
Ogden, Pat, Sensorimotor Psychotherapy Interventions for Trauma and, 2015thesis
you may discover a few resources in Phase 1 that help you feel ready to address memories in Phase 2, then work with relational issues using interventions in Phase 3—which may evoke intense emotions, sending you back to Phase 1 to develop more resources to regulate those emotions, and so forth.
Ogden demonstrates the non-linear, spiral character of phase-oriented treatment, showing how clients legitimately cycle among all three phases in response to emerging regulation needs rather than progressing sequentially.
Ogden, Pat, Sensorimotor Psychotherapy Interventions for Trauma and, 2015thesis
in the first phase of treatment, interventions must be chosen that facilitate both physiological and psychological homeostasis and that emphasize self-regulatory skills that maintain arousal within a window of tolerance and reduce or eradicate self-destructive tendencies.
Ogden articulates the rationale for Phase 1 primacy, arguing that premature memory work without somatic stabilization risks further destabilizing clients whose integrative capacity remains insufficient.
Ogden, Pat, Trauma and the Body: A Sensorimotor Approach to Psychotherapy, 2006thesis
A major goal of Phase 2 is that of resolving the phobia of traumatic memories among various parts of the personality, so that structural dissociation is rendered unnecessary. This phase of treatment generally requires patients to sustain a higher mental level than the one that existed when they entered treatment.
Van der Hart defines Phase 2 as the site of traumatic memory resolution, framing it in terms of the theory of structural dissociation and emphasizing that the elevated mental efficiency required mandates careful therapeutic pacing.
Hart, Onno van der, The Haunted Self Structural Dissociation and the Treatmentthesis
In phase 3 the therapeutic focus shifts to themes of self-development, adaptation to normal life, and relationships... full engagement in life is often not achieved without completion of phase 3 work.
Ogden argues that Phase 3 is indispensable for complete recovery, as it applies skills developed in earlier phases to the relational and developmental deficits that persist even after symptom reduction and memory processing.
Ogden, Pat, Trauma and the Body: A Sensorimotor Approach to Psychotherapy, 2006thesis
attachment issues generally manifest over all three phases of treatment. In early Phase 1, symptom reduction and stabilization, the patient or presenting dissociative parts typically may exhibit varying levels of avoidance.
Van der Hart demonstrates that attachment phobias are not phase-specific but permeate the entire course of phase-oriented treatment, requiring ongoing therapeutic attention across all three stages.
Hart, Onno van der, The Haunted Self Structural Dissociation and the Treatmentsupporting
Discussing together that the three phases of therapy occur in a spiral rather than linear fashion will increase clients' confidence in this model as a framework that is not rigid but holds their treatment flexibly and thoughtfully.
Ogden advocates communicating the spiral nature of the three-phase model directly to clients, positioning therapeutic transparency about phase structure as itself a stabilizing and confidence-building intervention.

Guided synthesis is the systematic (graduated) exposure of parts of the personality to traumatic memories with prevention of redissociation or avoidance. This must be done within the patients' mental level.
Van der Hart details the technical demands of Phase 2 memory work, specifying guided synthesis as the primary method for integrating traumatic memories while protecting against destabilizing redissociation.

the traumatic stress field needs more concerted efforts to study systematically the effectiveness of the principles and interventions of phase-oriented treatment of complex posttraumatic dissociative disorders.
Courtois identifies a critical gap in the evidence base, calling for systematic empirical investigation of phase-oriented treatment principles specifically as applied to complex posttraumatic dissociative conditions.

The three phases begin with learning to identify and develop a variety of resources—strengths, capacities, competencies, and skills—that can fortify your self-esteem and support you in maintaining your arousal within a window of tolerance.
Ogden frames Phase 1 resource-building as the foundation of phase-oriented work, locating somatic and psychological resource development as the precondition for all subsequent memory and relational phases.
Ogden, Pat, Sensorimotor Psychotherapy Interventions for Trauma and, 2015supporting
Contacting and expressing emotions requires that clients can utilize Phase 1 stabilization skills as needed. It will not be helpful to explore this chapter with dissociative clients until they have first achieved some control over the dysregulated arousal of their dissociative parts.
Ogden specifies sequencing criteria for dissociative clients, insisting that emotion work in later phases is contraindicated until Phase 1 stabilization skills are sufficiently established.

There is no research showing that these approaches represent adequate treatment for survivors of chronic traumatization if they are applied outside of
Van der Hart implicitly argues for the necessity of phase-oriented frameworks by contesting the adequacy of shorter single-modality approaches when applied without broader structural consideration to chronically traumatized populations.

Courtois enumerates the multi-domain treatment goals that phase-oriented approaches must address for complex PTSD, establishing the scope of work that justifies a structured, sequenced model.

Recognizing and including trauma recovery without memory work as a legitimate option for trauma healing increases the treatment options for clients and therapists alike.
Rothschild implicitly challenges the phase-oriented assumption that traumatic memory resolution is a necessary treatment goal, advocating for a broader conception of recovery that decouples stabilization-phase gains from mandatory memory-phase completion.
