KAP vs Somatic Experiencing
A side-by-side comparison of recorded mechanisms, evidence review status, related condition topics, and philosophical roots.
At a glance
Source checks, condition-specific assessments and expert review are separate steps. Each assessment applies only to its stated population and use. Topic links do not establish comparative effectiveness.

Guidelines and official sources (7)
6 clinical guideline checks · 1 regulatory source check
Read the recommendation and its scope. A source may discuss an approach without recommending it.
- SPRAVATO (esketamine) original prescribing information
Not a treatment recommendation
The historical drug indication is verified. It does not establish approval or guideline endorsement of KAP. This original label is not current prescribing information.
Scope: Esketamine nasal spray plus an oral antidepressant for adult TRD in 2019
- Management of Major Depressive Disorder
Discussed in the source
VA/DoD weakly suggests ketamine or esketamine augmentation. The recommendation concerns medication, not a named KAP psychotherapy protocol.
Scope: MDD after several adequate pharmacological trials have failed
- Clinical Practice Guideline for Management of PTSD and Acute Stress Disorder
Discussed in the source
VA/DoD weakly recommends against ketamine for PTSD. The statement concerns medication and does not separately evaluate KAP.
Scope: Ketamine pharmacotherapy for adult PTSD; not a separate KAP psychotherapy assessment.
- Assessment and Management of Patients at Risk for Suicide
Discussed in the source
VA/DoD weakly supports ketamine infusion for short-term ideation reduction; evidence for preventing attempts or suicide is insufficient. KAP is not separately recommended.
Scope: Adjunctive ketamine infusion in adults aged 18 and over with major depression and suicidal ideation; medication rather than KAP psychotherapy.
- Management of Major Depressive Disorder
Discussed in the source
VA/DoD suggests against ketamine/esketamine as initial pharmacotherapy (weak against). Its separate augmentation recommendation concerns prior treatment failure; neither recommendation endorses a named KAP psychotherapy protocol.
Scope: Adults choosing initial medication treatment for MDD.
- Management of Bipolar Disorder
Discussed in the source
VA/DoD finds insufficient evidence for ketamine/esketamine alone or as adjuncts. The recommendation concerns medication and does not endorse KAP psychotherapy.
Scope: Adults with acute bipolar depression.
- Clinical Practice Guideline for the Treatment of Posttraumatic Stress Disorder in Adults
Discussed in the source
APA reports insufficient evidence for ketamine in these comparisons. This is a drug-level finding, not a separate evaluation of the KAP psychotherapy protocol.
Scope: Adults with PTSD; ketamine compared with an active or inactive intervention.

How they work
KAP
Core mechanism: Ketamine's dissociative state, and the plasticity that follows it, are treated as a window for psychotherapeutic processing and new learning; the window is proposed rather than demonstrated
Ontology: Treatment-resistant conditions involve rigid neural patterns; ketamine disrupts rigidity and opens plasticity window
Somatic Experiencing
Core mechanism: Alternating in small doses between activation and a settled resource state ('pendulation') is held to complete defensive responses that were interrupted at the time of the threat and remain bound in the body
Ontology: Incomplete defensive responses (fight/flight/freeze) remain bound in the nervous system as undischarged survival energy

What each assumes — and misses
KAP
Philosophical roots: James (varieties of religious experience: altered states as data); Grof (non-ordinary states); Wolfson (ketamine as psychedelic medicine rather than anesthetic adjunct); neuroplasticity research
Blind spots: Regulatory fragmentation; limited standardization of psychotherapy component; risk of ketamine becoming the treatment rather than catalyst
Therapeutic voice: Last week you kept coming back to 'none of it is solid.' Let's stay there. What have you been treating as solid?
Somatic Experiencing
Philosophical roots: Reich/Lowen (body holds defense; Levine worked in this lineage but did not study with Reich, who died in 1957); Merleau-Ponty (lived body); Darwin (survival instincts); ethology (Tinbergen, Lorenz: animal defensive responses); James-Lange (emotion as bodily process)
Blind spots: Risk of over-physiologizing psychological meaning; limited manualization makes research difficult; can be vague in application
Therapeutic voice: Let's leave that where it is for a moment and come back to your feet on the floor. When you're ready we'll go back and take a smaller piece of it.
Choosing between them
KAP (Psychedelic) and Somatic Experiencing (Somatic) come from different traditions, which means they assume different things about what a person is, what causes suffering, and what the therapeutic relationship is for. The choice between them is often less about "which works better" and more about which set of assumptions fits the client and the therapist.
