  • Clinical Practice Guideline for Management of PTSD and Acute Stress Disorder

    VA/DoD · 2023 · Clinical guideline · Recommendation 8; Table 6, p.36

    Recommendation for the stated population

    EMDR is explicitly strongly recommended.

    Scope: Adults with PTSD

    Source checked

  • Post-traumatic stress disorder (NG116)

    NICE · 2018-12-05 · Clinical guideline · 1.6.18–1.6.20; child recommendation 1.6.13

    Recommendation for the stated population

    For adults, NICE considers EMDR at 1–3 months if preferred and offers it after 3 months for non-combat trauma. This scope is not a contraindication for combat trauma.

    Scope: Adults after non-combat trauma; separate restricted option for ages 7–17

  • Clinical Practice Guideline for the Treatment of Posttraumatic Stress Disorder in Adults

    American Psychological Association · Approved February 2025; 2025 update · Clinical guideline · Psychological intervention recommendations, printed page 7 (PDF page 11)

    Recommendation for the stated population

    APA conditionally recommends EMDR as a second-line adult PTSD treatment compared with no intervention or treatment as usual.

    Scope: Adults with PTSD; comparison with no intervention or treatment as usual

  • Clinical Practice Guideline for Management of PTSD and Acute Stress Disorder

    VA/DoD · 2023 · Clinical guideline · Recommendation 34; Table 6, p.38; discussion pp.82–83

    Discussed in the source

    VA/DoD suggests co-occurring disorders should not preclude these PTSD treatments. This addresses access to treatment, not a separate claim of treating substance use.

    Scope: PTSD with co-occurring substance-use disorder or other disorders; therapies named in recommendations 8 and 9.

  • Clinical Practice Guideline for the Treatment of Posttraumatic Stress Disorder in Adults

    American Psychological Association · Approved February 2025; 2025 update · Clinical guideline · Comparative psychological treatments, printed p.9 (PDF p.13)

    Insufficient evidence for or against

    APA finds insufficient evidence to prefer EMDR over those comparators. Its recommendation versus no treatment or usual care does not establish superiority over active therapy.

    Scope: Adults with PTSD; EMDR versus the other active psychological treatments listed in the table.

    World Health Organization · Third edition, 20 November 2023 · Clinical guideline · STR1, pp. 46–47 (PDF pp. 78–79)

    Recommendation for the stated population

    WHO includes EMDR in a conditional recommendation. The 2023 guideline book rates certainty as low, while WHO’s web summary reports moderate quality; that discrepancy remains unresolved. Delivery requires appropriate training and supervision.

    Scope: Adults with PTSD, within the mhGAP non-specialist-care context.

    World Health Organization · Third edition, 20 November 2023 · Clinical guideline · STR2, pp. 48–49 (PDF pp. 80–81)

    Recommendation for the stated population

    WHO includes EMDR in a strong recommendation based on moderate-certainty evidence. Clinicians need relevant training and demonstrated competence; lay providers require comprehensive training and close supervision.

    Scope: Children and adolescents with PTSD.

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.

PTSD & Acute Trauma

Population and scope: Adults with PTSD receiving individual, manualized EMDR. This does not grade acute post-trauma prevention, pediatric care, attachment-focused EMDR, ketamine-assisted EMDR or other branded adaptations.

Guideline recommendation

VA/DoD 2023 recommendation 8 strongly recommends EMDR for adult PTSD. The American Psychological Association’s 2025 guideline gives a conditional recommendation versus no intervention or usual care. For non-combat-related trauma, NICE NG116 (2018) offers EMDR after more than three months and considers it at one to three months when preferred. WHO STR1 is conditional; its 2023 book reports low certainty while its web summary reports moderate quality, an unresolved discrepancy. These differences remain visible: the label records a guideline recommendation for this adult PTSD protocol, not unanimous recommendation strength, universal first-line status or a claim that EMDR is unsuitable after combat trauma.

Perinatal Mental Health

Population and scope: Adults with PTSD after traumatic birth, miscarriage, stillbirth or neonatal death (NICE CG192 phrases this recommendation for women); standard manual-based EMDR within the non-combat PTSD pathway, rather than treatment of perinatal depression or distress alone.

Guideline recommendation

NICE CG192 offers trauma-focused CBT or EMDR for PTSD resulting from traumatic birth, miscarriage, stillbirth or neonatal death, referring to its PTSD guideline. NICE NG116 distinguishes timing: consider EMDR at one to three months after non-combat trauma when it is preferred, and offer it after three months. It specifies a validated manual and trained, supervised practitioners. This supports EMDR for the stated trauma-related PTSD context, not a general treatment for perinatal depression, grief without PTSD, or prevention in every pregnancy. CG192 separately advises against single-session high-intensity interventions that explicitly relive traumatic birth. These recommendations do not establish safety for every pregnancy or endorse all EMDR adaptations.

PTSD & Acute Trauma

Population and scope: Adults with PTSD receiving 16-week online IFS-based PARTS groups plus eight individual counseling sessions.

Randomized studies

Joss and colleagues (2026) randomized 60 patients to PARTS or matched nature-based stress reduction. Both arms improved on clinician-rated PTSD without a significant between-arm difference; PARTS had higher attendance and satisfaction. This supports existence of a randomized study, not superiority or evidence for unrestricted individual IFS.

How they work

EMDR

Core mechanism: Bilateral stimulation during trauma memory processing facilitates adaptive information processing and memory reconsolidation (proposed)

Ontology: Unprocessed trauma memories stored dysfunctionally with original affect, sensation, and cognition

IFS

Core mechanism: Self-energy (curiosity, compassion, calm) accesses and unburdens exiled parts; protector parts relax when exiles are healed

Ontology: Internal system of parts carrying burdens from attachment injuries; protectors manage exiles' pain

What each assumes — and misses

EMDR

Philosophical roots: Merleau-Ponty (body holds memory); Bion (processing/containment); Pavlov (orienting response); Shapiro (adaptive information processing: pragmatic, not philosophically derived)

Blind spots: Mechanism debate unresolved; protocol fidelity varies; may be applied to conditions beyond its evidence base

Therapeutic voice: Bring up the image and the negative belief. Notice what you feel in your body. Now follow my fingers.

IFS

Philosophical roots: Systems theory (Bertalanffy); Schwartz (inner system as family); Jung (subpersonalities, Self); Buddhist concept of witnessing awareness (Self-energy); multiplicity of mind (Ornstein, Minsky)

Blind spots: Popularity far outpaces evidence base; parts language can become reified; randomized evidence is limited to one rheumatoid-arthritis trial and one group PTSD trial that did not outperform its active control

Therapeutic voice: Can you ask that critical part what it's afraid would happen if it stepped back?

Choosing between them

EMDR (Trauma-Focused) and IFS (Family Systems) 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.
