EMDR and IFS: How the Two Therapies Work Together

EMDR and Internal Family Systems (IFS) are two different trauma approaches that fit together well. EMDR is a structured, eight-phase protocol that helps the brain reprocess specific traumatic memories. IFS is a parts-based model that helps you understand and lead your inner system of protective and wounded parts. Combined, IFS-informed EMDR uses parts work to build safety and consent inside the EMDR protocol, so memory processing goes at a pace your whole system can handle.

This guide explains what each therapy does, where they differ, how clinicians blend them, and what to ask before you start.

TL;DR

EMDR targets specific memories using alternating bilateral stimulation. IFS works with the relationships among your inner parts and your core Self.
In an integrated approach, IFS-style parts work is used inside EMDR's eight phases, for example to check whether protective parts are willing before a memory is processed.
The combination is often discussed for complex trauma and childhood trauma, where one part of you may want to heal while another part fears it.
The approach needs a clinician trained in the EMDR protocol who also screens for dissociation and keeps parts work from becoming a way to avoid memory work.
You do not need to pick one forever. The question is which one leads at which stage of your healing.

What EMDR does

Eye Movement Desensitization and Reprocessing (EMDR) is a trauma therapy built on the idea that distressing experiences can get stuck, stored in a raw form, and keep firing as if they were happening now. During sessions, you briefly hold a target memory in mind while following alternating bilateral stimulation, usually eye movements, taps or tones. A 2025 academic paper on IFS-informed EMDR describes it as processing traumatic memories into adaptive memory networks.

EMDR follows an eight-phase protocol: history taking, preparation, assessment, desensitization, installation, body scan, closure and reevaluation. A great deal of the work happens before any memory is processed. The American Psychological Association's PTSD guideline places EMDR among the psychological treatments it addresses for adults with PTSD, which is one reason it is widely offered in clinics across the U.S.

If you want the full walk-through of each phase, our step-by-step EMDR therapy guide covers what happens in the room.

What IFS does

Internal Family Systems was developed by Richard Schwartz. It starts from the premise that the mind is naturally made up of multiple parts, and that everyone also has a core Self. The academic literature describes IFS as embracing this "psychic multiplicity" and treating Self-energy as a different kind of part that exists within everyone.

IFS usually sorts parts into three groups:

Managers run daily life: the planner, the perfectionist, the inner critic, the caretaker.
Firefighters react when pain breaks through: numbing, bingeing, rage, shutting down, dissociating.
Exiles hold the hurt, shame or fear from earlier experiences, often childhood ones. Protectors work hard to keep them out of sight.

The goal is not to get rid of parts. Per EMDRIA's overview, IFS helps clients reorganize their internal system so it becomes Self-led, by connecting the Self with each part.

What parts work means in practice

"Parts work" is the everyday name for the IFS way of listening inside. You notice a reaction, such as a tight chest before a hard conversation or an urge to cancel therapy, and treat it as a part with its own job and history rather than as something wrong with you. From a calm, curious place, you ask what it is afraid would happen if it stopped.

A short example: a client wants to process a memory of being yelled at as a child, but every time she tries, she feels sleepy and foggy. A parts approach would not push through the fog. It would ask the foggy part what it is protecting her from, and what it needs before the memory comes up. Often the answer is a form of safety that has nothing to do with the memory itself.

EMDRIA describes parts work as identifying the subpersonalities that carry trauma or protective burdens and guiding the client to connect with them from the core Self. In EMDR, that can be used to gain the consent of protector parts before specific memories are processed.

EMDR vs. IFS: the main differences

Both therapies aim to relieve the burden of past experiences, but they get there differently.

	EMDR	IFS
Main focus	Specific traumatic memories and the beliefs attached to them	The whole inner system and the relationships among parts
Core method	Alternating bilateral stimulation while a target memory is held in mind	Dialogue between your Self and individual parts
Structure	Eight-phase protocol	Flexible, guided by what parts need, with a sequence of steps for each part
Preparation	Extensive history taking and phase-two preparation	Minimal grounding and regulation training, with emphasis on part-to-Self connection
Typical goal	Memory loses its charge and links with adaptive information	Parts unburden and the Self leads

The differences in the last two rows come from an EMDR Association UK comment piece, which notes that EMDR spends considerable time on history and preparation, while IFS keeps preparation light and focuses on connecting parts with Self.

The same source offers a useful way to think about the gap. IFS treats the system as a whole and negotiates with parts. EMDR is a protocol that processes specific memories. It also observes that EMDR can sometimes move past managers and reach exiles before the system is ready, while IFS supplies tools to negotiate with managers and settle inner conflicts.

Why the two fit together

The pairing is not just a clinical trend. In a 2023 paper, Hersey and Richardson argue that IFS's Self and burdened part map onto EMDR's adaptive network and target network. That correspondence, they suggest, makes IFS an especially good ego-state therapy to pair with EMDR.

In plain terms: EMDR already assumes that a stuck memory (the target) can link with healthier information (the adaptive network). IFS offers a relational language for the same idea. The wounded part is the target, and the Self is the calm, capable presence that can hold it.

How therapists blend IFS into the eight phases

IFS-informed EMDR keeps the EMDR protocol intact and borrows parts-based tools at specific points. EMDRIA's magazine describes integrating IFS interventions within the eight phases, for example permission checks in phase two, or resolving looping in phase four, while adhering to the overall protocol.

Here is how that can look across the process:

History taking (phase 1). The clinician maps not only events but also the protectors that grew up around them. Which part keeps you busy? Which part goes numb?
Preparation (phase 2). Parts are introduced to the client's Self, and protectors are asked for permission. An EMDRIA author finds IFS interventions particularly helpful in phases 1 and 2 for befriending protective parts, and notes that checking their concerns may reduce the risk of adverse reactions or decompensation.
Assessment and desensitization (phases 3 and 4). Bilateral stimulation begins on the target memory. If processing loops or stalls, the clinician may pause to ask which part is interrupting and what it fears.
Installation, body scan and closure (phases 5 to 7). The adaptive belief is strengthened and the session ends with the system settled, including thanking the parts that stepped back.
Reevaluation (phase 8). You and your clinician check what shifted and whether any part still carries a burden.

EMDRIA also notes that integrating IFS can support a consent-based, relational approach, especially with complex trauma, by helping the clinician attune to your internal system before reprocessing begins.

Who might consider EMDR, IFS or both

No single approach suits everyone, and the right fit depends on your history, your symptoms and how you relate to your own inner world. These are common situations where people ask about a combination:

A single-incident trauma such as an accident or assault. A standard EMDR protocol may be enough, and parts work stays in the background.
Childhood or complex trauma. Here, protective parts often have strong views about what is safe. A parts-informed approach gives them a voice instead of overriding them. Our page on PTSD and complex trauma explains how we think about this kind of care.
A pattern of inner conflict. One part wants to leave a relationship, another is terrified of being alone. IFS language helps name the tug of war, and EMDR can then target the memories feeding it.
Previous therapy that stalled. If talk therapy kept you in your head, or if you froze whenever a memory came up, a parts-aware EMDR approach may feel more workable.
Relationship wounds. Betrayal and attachment injuries often involve both memories and strong protective reactions. See how this plays out in EMDR and relationships.

If you are still weighing whether to start with EMDR or with a parts-based approach, a short consultation with a trauma-informed clinician is the most reliable way to decide. The right starting point depends on your history, which an article cannot assess.

Precautions: pacing, dissociation and keeping the protocol

Integration only helps when it is done carefully. Three issues matter most.

Screening for dissociation. If you tend to lose time, feel unreal or detach under stress, a clinician should assess this before reprocessing begins. Our post on screening questions before EMDR for dissociation lists what a careful clinician asks. Parts language can be especially vivid for people who dissociate, so pacing matters.

Clinician-imposed parts. A guide to integration warns of the risk of therapists imposing parts on clients, and of using parts dialogue to dodge memory work rather than process it. You should feel free to say "that doesn't fit for me" and have the clinician follow your experience, not a script.

Preparation differs by model. EMDR expects thorough preparation, while IFS keeps it light. When blending them, a good clinician decides how much stabilization you need based on you. Sometimes that is substantial, and sometimes it is less than people assume. Our article on when to skip stabilization in EMDR for complex PTSD explains how that call is made.

After a session, expect that feelings and dreams may be vivid for a day or two. Your clinician should give you a plan for grounding, rest and contact if things feel too intense. If you ever feel unsafe or in crisis, call or text 988, the Suicide & Crisis Lifeline, in the U.S.

Our perspective

We see people every week who say the same thing: one part of me wants to heal, and another part is terrified of it. That tension is not resistance to be pushed through. It is information about pace.
Our work is rooted in EMDR and in trauma-informed care, and we take the idea behind parts work seriously: protective reactions exist for a reason, and the safest route to a painful memory goes through the system that has been guarding it. Consent, pacing and screening for dissociation are not extras for us. They are part of doing EMDR well.
For many clients, that means a careful history, honest conversations about what feels safe, and, when it helps, a format that gives protective reactions more room. Some clients prefer shorter weekly sessions. Others want focused time in an intensive. We offer both, in English and Spanish, and we shape the plan around the person, not the other way around.
If you are curious whether a parts-aware EMDR approach fits your story, ask us how we would pace your work. A good clinician welcomes that question.

What to ask a clinician before you begin

Whether you are looking at us or anywhere else, these questions help you judge fit:

Are you trained in EMDR, and how do you use the eight phases with someone with my history?
What training do you have in parts-based work, and how do you use it inside EMDR?
How do you screen for dissociation, and what happens if it shows up mid-session?
How will you check with my protective parts, or my hesitations, before processing a memory?
What is the plan if a session stirs up more than I expected?
Can you work in my language and understand my cultural background?

A clinician who answers these plainly, without rushing you, is usually one worth trusting.

FAQ

Is EMDR or IFS better for trauma?

Neither is better in every case. EMDR is a protocol aimed at processing specific memories, while IFS is a model for understanding and leading your inner system. Many people with complex trauma benefit from having both in mind, with the order decided by what feels safe for you.

Who is IFS therapy for?

IFS is used with adults, couples and families, and is often discussed for trauma, anxiety, grief and inner conflict. It tends to suit people who can get curious about their reactions and want a relational way to understand them. A clinician can help you judge whether it fits your current stage of healing.

Can you do parts work and EMDR in the same session?

Yes, when the clinician is trained for it. Parts work is typically used to check permission from protectors, resolve looping during processing, or settle the system at closure, while the EMDR protocol stays in place.

What should I not do after EMDR?

Avoid scheduling something demanding right after a session, and go easy on alcohol and other substances that blunt your processing. Plan for rest and grounding, and expect vivid feelings or dreams for a day or two. Share anything that worries you with your clinician before the next session.

Is IFS-informed EMDR a different therapy?

It is better described as EMDR with parts-based tools added. The eight-phase structure stays, and IFS ideas shape how preparation, consent and difficult moments are handled.
