Condition-specific assessments

Each conclusion applies to the population and use described. These source-based assessments do not certify the full entry or replace expert clinical review.

Dissociative Disorders

Population and scope: One middle-aged woman with SCID-D-diagnosed dissociative identity disorder; relational art therapy combined with DBR during ongoing multimodal psychotherapy.

Limited evidence

Gerge and colleagues (2025) describe reduced depersonalization and greater bodily connection in a single case. This uncontrolled, combined-treatment report cannot establish either component’s independent effect, comparative efficacy, remission, or generalization to other dissociative disorders.

• Gerge et al. (2025): art therapy and DBR in a single DID case

PTSD & Acute Trauma

Population and scope: 54 adults with PTSD randomized to eight videoconference DBR sessions or waitlist.

Randomized studies

Kearney and colleagues (2023) report an interim randomized analysis with greater clinician-rated PTSD improvement for DBR at post-treatment and three-month follow-up. The small waitlist-controlled study does not establish comparative efficacy against established active therapies or confirm its proposed neural mechanism.

  Discussed in the source

  Structural dissociation is discussed as one etiological model. This does not make it a separately recommended treatment or the sole basis of the guideline.

  Scope: Conceptual models of adult dissociative identity disorder.

Deep Brain Reorienting

Core mechanism: Tracking the orienting sequence (superior colliculus → locus coeruleus → periaqueductal grey) at the speed the brainstem actually processes it allows the interrupted shock response to complete before affect floods the system

Ontology: Trauma is encoded first as a pre-affective brainstem shock, an interrupted orienting response held in midbrain circuitry, beneath and prior to emotional or narrative memory

Structural Dissociation

Core mechanism: Phase-oriented treatment: (1) stabilize ANP functioning and reduce EP intrusions, (2) process traumatic memories to resolve phobia of trauma-related content, (3) integrate dissociated parts into a more unified personality

Ontology: Trauma structurally divides the personality into parts organized around incompatible action systems: daily life management (ANP) and survival defense (EP); healing requires phased integration of what was dissociated

Deep Brain Reorienting

Philosophical roots: Janet (interrupted action, phase-oriented treatment); Levine (incomplete defensive response); Porges (neuroception, brainstem safety detection); Panksepp (subcortical affective neuroscience); Corrigan (brainstem self-other system)

Blind spots: One developer-involved interim trial with no active comparator and a baseline group difference on arousal symptoms; the brainstem mechanism remains a published hypothesis rather than a demonstrated pathway; no evidence yet on whether the pre-affective focus helps or hinders clients whose distress is primarily relational or meaning-based; small trained practitioner pool, with training concentrated in the UK, Europe, North America, and Australasia

Therapeutic voice: Before the emotion came, something in your neck turned toward it. Can we slow down and stay right there, just at the turning?

Structural Dissociation

Philosophical roots: Janet (dissociation, fixed ideas, action systems); Myers (shell shock, apparently normal/emotional personality); Bowlby (attachment); evolutionary psychology (action systems); van der Kolk (body keeps the score)

Blind spots: Phase-oriented approach can become indefinite stabilization that avoids processing; the model is complex and requires training specifically in dissociative disorders rather than general trauma training, and is not safe to improvise without it; presentations where a simpler trauma treatment would be sufficient are a fit question rather than a safety one; may pathologize adaptive dissociation in some cultural contexts

Therapeutic voice: The part of you that goes to work and pays the bills, and the part that wakes up screaming: they're both you. Right now they don't know each other very well. Our work is to help them communicate.
