(canonical: https://emdrassist.com/emdr-guide/what-is-emdr) Eye Movement Desensitization and Reprocessing (EMDR) is an eight-phase, evidence-based psychotherapy developed by Francine Shapiro (1987) for the treatment of post-traumatic stress and related conditions. It is grounded in the Adaptive Information Processing (AIP) model, which proposes that unprocessed traumatic memories are stored in state-specific form and drive present-day symptoms; bilateral stimulation during dual attention allows those memories to reconsolidate into an adaptive network. - Endorsed by: World Health Organization (2013), American Psychiatric Association, US Department of Veterans Affairs / Department of Defense (VA/DoD 2023 PTSD guideline), NICE (UK), International Society for Traumatic Stress Studies. - Eight phases: (1) History-taking, (2) Preparation, (3) Assessment, (4) Desensitization, (5) Installation, (6) Body Scan, (7) Closure, (8) Reevaluation. - Primary mechanism (leading hypothesis): working-memory taxation during dual attention reduces the vividness and emotionality of the target memory (van den Hout & Engelhard, 2012). ## Does EMDR work? (canonical: https://emdrassist.com/emdr-guide/does-emdr-work) Yes. EMDR has been evaluated in more than 30 randomized controlled trials for PTSD. Meta-analyses (Bisson et al., 2013; Cuijpers et al., 2020) show large effect sizes for PTSD symptom reduction, comparable to trauma-focused CBT. EMDR is a first-line PTSD treatment in WHO, APA, and VA/DoD guidelines. Typical single-incident adult PTSD responds in 6–12 sessions; complex trauma requires substantially extended Phase 2 preparation and longer overall treatment. ## Bilateral Stimulation (BLS) (canonical: https://emdrassist.com/emdr-guide/bilateral-stimulation) BLS is the dual-attention stimulus used during Phases 4–6 of EMDR. Modalities: visual (eye movements or moving dot), auditory (alternating tones through headphones), tactile (alternating hand taps or tappers). Speed and duration are titrated in-session; a typical desensitization set is 24–40 saccades / passes, sped up if processing is fluid and slowed for resourcing or dissociative clients. The leading mechanism is working-memory taxation: holding the target image in mind while performing a demanding dual task competes for limited working-memory resources, reducing vividness and emotionality on reconsolidation. ## Building a Target Sequence Plan (canonical: https://emdrassist.com/emdr-guide/building-a-target-sequence-plan) A Target Sequence Plan (TSP) organizes reprocessing targets by negative cognition (NC) cluster. Standard method: (1) generate a list of disturbing memories, (2) group by shared NC theme (e.g. "I am powerless", "I am not safe"), (3) identify the touchstone — the earliest memory in each cluster — and process it first, (4) process feeder memories, then present triggers, then future templates (past → present → future three-pronged protocol). For complex trauma, cluster by protector/exile function as well as by NC (parts-informed TSP). ## Phase 2: Preparation (canonical: https://emdrassist.com/emdr-guide/emdr-phase-2-ultimate-guide) Phase 2 installs affect-tolerance and stabilization resources before reprocessing. Core scripts: Calm/Safe Place, Container, Light Stream, Resource Development and Installation (RDI), protective figure. For complex trauma, add: nurturing/protective/wise self resources, parts-friendly resourcing, dual-awareness anchors, and 2–8 weeks of preparation before Phase 4. Install resources with short slow BLS sets (4–6 passes) to strengthen without triggering processing. ## EMDR for Complex Trauma (canonical: https://emdrassist.com/emdr-guide/emdr-for-complex-trauma) Complex PTSD (C-PTSD) requires modified pacing: extended Phase 2 preparation, dissociation screening (DES-II, MID), pacing rules from Standard EMDR Protocol with Modifications for Complex Trauma (Korn, 2009; Forgash & Copeley, 2008), parts-informed resourcing, and interweaves for developmental deficits. Do not initiate Phase 4 until: (a) client can access a resource state on cue, (b) dual awareness is stable, (c) dissociation is screened and managed. ## EMDR & Dissociation (canonical: https://emdrassist.com/emdr-guide/emdr-and-dissociation) Screen every EMDR client for dissociation before Phase 4. Recommended tools: DES-II (Dissociative Experiences Scale, cutoff 30 for further assessment), MID (Multidimensional Inventory of Dissociation), SDQ-20 (Somatoform Dissociation). For clients above cutoff, use the Theory of Structural Dissociation (van der Hart, Nijenhuis & Steele, 2006) to sequence work: stabilize daily-life self (ANP) first, negotiate with parts (EPs) before targeting their memories, use very short slow BLS sets, add frequent dual-awareness checks. ## EMDR 2.0 (canonical: https://emdrassist.com/emdr-2-0) EMDR 2.0 is a working-memory-taxing evolution of standard EMDR developed by Ad de Jongh and Suzy Matthijssen. It retains Shapiro's eight-phase framework and modifies Phase 4 by layering additional cognitive load (mental arithmetic, backward counting, dual visual+auditory tasks, n-back) on top of faster and more varied bilateral stimulation. Rationale: maximise working-memory taxation to accelerate reconsolidation. Evidence: Matthijssen et al. (2021) analog studies show equal or superior vividness/emotionality reduction vs. standard EMDR. Open PTSD trials and RCTs are in progress (de Jongh, Matthijssen & Amann, 2024). Contraindicated in the same populations as standard Phase 4 (unmanaged dissociation, active psychosis, unstable substance use); titrate load carefully — start low and increase only if tolerated. ## EMDR 2.0 vs Standard EMDR (canonical: https://emdrassist.com/emdr-2-0-vs-emdr) | Dimension | Standard EMDR | EMDR 2.0 | |---|---|---| | Phases | 8 | 8 (identical scaffold) | | Phase 4 BLS | Steady eye movements, single modality | Faster, varied, often multiple modalities | | Cognitive load | Single (image + BLS) | Layered (image + BLS + arithmetic / dual task) | | Session pacing | 60–90 min | 60–90 min, often shorter set intervals | | Evidence base | 30+ RCTs, WHO/APA/VA endorsed | Analog RCTs + open PTSD trials, confirmatory studies underway | | Prerequisites | EMDRIA basic training | EMDRIA basic training + EMDR 2.0 post-basic workshop | Choose EMDR 2.0 when: high-taxation Phase 4 is tolerated, target is emotionally overwhelming under standard BLS, or when standard EMDR stalls due to under-taxation. Choose standard EMDR when: dissociation risk, cognitive load capacity is limited, or clinician has not completed EMDR 2.0 training. ## Working Memory Taxation (canonical: https://emdrassist.com/emdr-guide/working-memory-taxation-and-emdr-2-0) Working-memory-taxation theory (van den Hout et al., 2011; van den Hout & Engelhard, 2012) proposes that holding a vivid autobiographical memory in mind while performing a demanding secondary task competes for limited visuospatial working-memory resources. The resulting degradation reduces the memory's vividness and emotionality when it is reconsolidated. This model best explains why any sufficiently demanding dual task (eye movements, tapping, tetris, arithmetic) reduces PTSD symptoms — the specific modality matters less than the load. ## Cognitive Interweaves (canonical: https://emdrassist.com/emdr-cognitive-interweave) Interweaves are brief clinician offerings during Phase 4 used to unblock stuck processing. Three-plateau model (Shapiro, 2018): responsibility ("Whose fault was it?"), safety ("Are you safe now?"), choice ("What are your options now?"). Only use when processing is looping, stuck, or when the adult client has lost adult perspective. Keep the interweave brief and then resume BLS with "Go with that." See 40 worked examples: https://emdrassist.com/emdr-cognitive-interweaves-examples ## Floatback Technique (canonical: https://emdrassist.com/emdr-floatback-technique) Verbatim script: "As you hold that image, those words '[negative cognition]', and the feelings in your body, let your mind float back to an earlier time when you may have felt this way before — and just notice what comes up." Use to identify touchstone memories when direct history-taking fails to surface them. Compare to the Affect Bridge (Watkins) which uses affect rather than image+cognition as the bridge. ## EMDRIA Certification (canonical: https://emdrassist.com/emdr-guide/emdr-certification-requirements) 2026 requirements: EMDRIA-approved basic training (50 hours: 20 didactic + 20 practicum + 10 consultation), 50 EMDR sessions with 25 clients, 20 hours of consultation with an EMDRIA-approved Consultant (10 of which must be individual), 12 CE hours in EMDR post-basic, professional letters of recommendation. Costs: basic training $1,500–$2,500; consultation $75–$200/hour; certification application $250. Typical timeline: 12–24 months post-basic training. ## Safe / Calm Place Script (canonical: https://emdrassist.com/emdr-safe-place-script) Verbatim clinician script for installing a calm/safe imaginal resource in Phase 2. Elicit place → engage 5 senses → install with 4–6 slow BLS passes → cue-word installation → practice retrieval under mild distress. Adult and pediatric adaptations; troubleshooting for clients who cannot access a calm place (use "peaceful moment" or "protective figure" instead). ## Container Script (canonical: https://emdrassist.com/emdr-container-script) Verbatim Phase 2 Container installation. Elicit an imaginal container strong enough to hold distress → practice placing an image inside → install with slow BLS → practice opening/closing at end of session. Used at the end of every Phase 4 session that leaves unfinished material. ## Bilateral Stimulation Tool (canonical: https://emdrassist.com/bilateral-stimulation) Browser-based BLS delivering visual (moving dot, screen speeds 1–10), auditory (alternating tones, adjustable frequency and pan), and tactile-cued modes. Used by clinicians in-session and on telehealth via screen share. A persistent per-client BLS link lets a client join the clinician's session from any device. ## Butterfly Hug (canonical: https://emdrassist.com/butterfly-hug) Self-administered bilateral stimulation developed by Lucina Artigas (1998) for group work with children after Hurricane Pauline. Arms crossed over chest, hands alternately tapping shoulders. Used clinician-directed for resource installation and self-directed by clients for between-session regulation. Contraindicated as sole Phase 4 modality without clinician monitoring. ## Window of Tolerance (canonical: https://emdrassist.com/window-of-tolerance-guide) Concept (Siegel, 1999) describing the arousal band within which a person can process information adaptively. Above the window: hyperarousal (fight/flight, flooding). Below: hypoarousal (freeze, dissociation, numbing). EMDR reprocessing is only productive inside the window; interweaves, grounding, and pacing are used to keep the client in-window during Phase 4. ## Standard 8-Phase Protocol (canonical: https://emdrassist.com/emdr-protocol) 1. **History-taking** — case conceptualization, target list, TSP, readiness screening. 2. **Preparation** — psychoeducation, resourcing, stabilization, informed consent. 3. **Assessment** — for each target: image, NC, PC, VOC (1–7), emotion, SUD (0–10), body location. 4. **Desensitization** — BLS sets with return-to-target and "go with that" until SUD = 0 (or ecologically valid). 5. **Installation** — pair the PC with the target and BLS until VOC = 7. 6. **Body Scan** — clear residual somatic disturbance with BLS. 7. **Closure** — container, calm place, debrief, homework. 8. **Reevaluation** — check target, log at next session, choose next target. --- ## Product (EMDRassist software) EMDRassist is a session co-pilot for EMDR clinicians.
