Internal Family Systems (IFS) Therapy: Research, Evidence & What to Expect
Quick Answer: What Is IFS Therapy?
Internal Family Systems (IFS) is a non-pathologizing approach to psychotherapy that identifies and heals multiple inner “parts” — wounded Exiles and protective Managers and Firefighters — by accessing the undamaged, compassionate core Self. Originally developed by Dr. Richard Schwartz, IFS is designated an evidence-based practice by SAMHSA and has shown promise for depression, PTSD, chronic pain, and self-compassion in peer-reviewed research.
Imagine your mind as a family. Some members are protective, some wounded, some reactive and all of them have a reason for behaving the way they do. That’s the core insight behind Internal Family Systems (IFS), a psychotherapy model developed in the 1990s by Dr. Richard Schwartz.
“What I heard repeatedly were descriptions of what they often called their ‘parts’ the conflicted subpersonalities that resided within them.”
IFS teaches that the mind is naturally multiple and that this multiplicity is healthy. Inner parts are pushed into stressful situations, but every part, even one driving destructive behavior has a positive intent. The goal isn’t to eliminate parts; it’s to free them from those extreme roles and restore harmony under the leadership of the core Self.

Is IFS Therapy Effective? What the Research Actually Says
IFS has grown enormously in popularity, but popularity and efficacy aren’t always the same thing. Here’s an honest look at what the evidence shows and where the gaps remain.
Latest Research Findings (2024–2025)
-
•
Promising for PTSD, Depression & Pain: A 2025 scoping review (Buys, M.E., Taylor & Francis) consolidates peer-reviewed IFS research, highlighting it as promising for chronic pain, depression, and PTSD, and for developing self-compassion and self-forgiveness.
-
•
Evidence-Based Practice Status: In 2015, IFS was designated an evidence-based practice on SAMHSA’s National Registry (NREPP), supported by randomized controlled trials showing improvements in rheumatoid arthritis symptoms, depressive symptoms, and self-compassion.
-
•
Emerging, Not Conclusive: The IFS Institute itself acknowledges that “larger, fully-powered clinical trials are needed for each clinical indication.” The current evidence base, while promising, it is based on small RCTs and quasi-experimental studies.
-
•
Smaller Base Than CBT: IFS does not yet have as strong an evidence base as Cognitive Behavioral Therapy (CBT) or EMDR. Clinicians and clients should weigh this when choosing a therapeutic approach.

When IFS Is Not Appropriate
IFS is generally not recommended for individuals with schizophrenia, active psychosis, or paranoia. Describing the mind as having “parts” can be disorganizing, even harmful for those who struggle with reality testing. Always consult a licensed mental health professional for assessment. At Sandoval Therapy we can help diagnose and determine if IFS is appropriate for you.
How Is IFS Different from CBT and EMDR?
Choosing a therapy often means understanding what makes each one different. Here’s a direct comparison:
| Feature | IFS Therapy | CBT | EMDR |
|---|---|---|---|
| Core Concept | Multiplicity of mind (Parts + Self) | Maladaptive thought patterns | Traumatic memory reprocessing |
| Primary Goal | Harmonize internal system via Self-leadership | Modify thoughts & behaviors | Desensitize & reprocess trauma memories |
| View of Symptoms | Protective roles with positive intent | Patterns to be restructured | Unprocessed memories causing distress |
| Approach to Trauma | Dialogue with Parts carrying trauma | Cognitive restructuring + exposure | Bilateral stimulation (eye movements/tapping) |
| Evidence Base | Emerging (SAMHSA recognized, 2015) | Strong (decades of RCTs) | Strong (WHO-recommended for PTSD) |
| Can They Combine? | Yes — IFS + EMDR widely integrated | Often combined with DBT | Often combined with somatic work |
IFS + EMDR: A Growing Integration
Many EMDR practitioners now integrate IFS when working with complex trauma or dissociation. The IFS “parts” framework helps stabilize a client’s internal system before EMDR reprocessing begins — particularly useful when clients feel overwhelmed or “hijacked” by their Firefighter parts during trauma work. Here at Sandoval Therapy our therapists are trained in both EMDR & IFS — talk with us to see which approach is best for you!
Understanding the Core Roles: Managers, Exiles, and Firefighters
In IFS, every part has a role. Understanding these roles is key to understanding why you feel or behave the way you do and why those parts developed in the first place.
Managers (Proactive Protectors)
These protective parts try to maintain control and prevent you from being overwhelmed by pain. They manage daily life your inner perfectionist, inner critic, inner planner working hard to keep the system stable and avoid distress.
Example: The part of you that overworks to avoid sitting with painful feelings.
Exiles (Wounded Parts)
Exiles carry painful emotions and memories often from childhood such as shame, fear, or grief. They are pushed out of conscious awareness by Managers to protect the system from being overwhelmed.
Example: The young, frightened part of you that experienced early abandonment or abuse.
Firefighters (Reactive Protectors)
Firefighters emerge when Exiles threaten to break through. They drive impulsive, often destructive behaviors like substance use, binge eating, rage, dissociation to “put out the fire” of overwhelming pain as fast as possible. Crucially, they intend to protect, even when they cause harm.
Example: The part that reaches for alcohol when anxiety spikes past a certain threshold.
“One of the model’s distinguishing features is its insistence that there are no ‘bad’ parts; every part, even those driving destructive behavior, is understood to have a positive intent within the system.”
What Are the 6 Steps of IFS Therapy?
At Sandoval Therapy we follow a structured six-step process, sometimes called the “6 Fs” to help clients identify, befriend, and ultimately unburden their parts:
Find
Identify the parts of your mind and body that need attention.
Focus
Pay sustained attention to the relevant part and notice its presence.
Flesh
Describe it in detail what does it look like, feel like, sound like?
Feel
Notice how you (your Self) feel toward this part curious, frustrated, compassionate?
BeFriend
Approach the part with genuine curiosity and accept its presence without judgment.
Fear
Ask what the part fears would happen if it let go of its extreme role.
What Is the “Self” in IFS? The 8 C’s and 5 P’s
In IFS, the “Self” is your undamaged, compassionate core, distinct from all your parts. It was never harmed; it is always there. Our therapists use the 8 C’s and 5 P’s to identify how much Self-leadership is present in a given moment.
The 8 C’s of Self
The 5 P’s of Self
These qualities indicate Self-leadership, the goal of IFS therapy.
What Should I Expect in My First IFS Session?
Your first IFS session is less about recounting your history and more about turning inward. One of our trained IFS therapists will help guide you through mapping your internal system with curiosity rather than judgment.
Mapping Your Internal System
Your therapist will guide you to notice the parts that show up, perhaps a worried Manager, a self-critical voice, or a numb feeling. Rather than analyzing them, you’ll observe them from your Self’s perspective.
Speaking For, Not About
A key IFS technique is inviting you to “speak for” your parts, saying “a part of me feels angry” rather than “I am angry.” This creates important distance that allows curiosity to replace reactivity.
Visualization & Body Awareness
Your therapist may use relaxation exercises, guided imagery, journaling, or body-based awareness to help you locate parts. There’s no forced exposure to trauma the process unfolds at a pace your system can handle.
No “Bad” Parts
From your very first session, your therapist will reinforce that every part, even the ones you dislike, has a role and a positive intent. This non-pathologizing stance is often experienced as profoundly relieving.
How to Find the Right IFS Therapist for You
Finding an Internal Family Systems (IFS) therapist is about more than credentials, it’s about finding someone who helps you feel safe, understood, and supported in the healing process.
Look for Specialized IFS Training
When searching for an IFS therapist, look for licensed mental health professionals — LMFTs, LCSWs, PsyDs, or PhDs — who have completed formal Internal Family Systems training through the IFS Institute. Many therapists complete Level 1, 2, or 3 training, while IFS-C certification reflects advanced competency in the model.
At Sandoval Therapy, we integrate IFS therapy with trauma-informed approaches to help clients better understand protective patterns, emotional wounds, and the parts of themselves that may feel stuck, overwhelmed, anxious, or disconnected. We serve adults and couples throughout Pasadena and the greater Los Angeles area.
Find an IFS Therapist Who Understands Trauma
IFS therapy can be especially powerful for individuals navigating:
- • Childhood trauma
- • Anxiety and depression
- • Relationship struggles
- • Cultural or generational trauma
- • Emotional overwhelm
- • Self-criticism or shame
If you have a history of trauma, it’s important to work with a therapist who understands how trauma affects the nervous system and emotional safety. Our practice combines IFS-informed therapy with evidence-based trauma approaches to support deeper healing without judgment or retraumatization.
The Therapeutic Relationship Matters
Research consistently shows that the quality of the therapeutic relationship is one of the strongest predictors of successful therapy outcomes. Feeling emotionally safe, heard, and connected in therapy matters.
Looking for an IFS Therapist in the Los Angeles Area?
At Sandoval Therapy, we help adults and couples explore patterns rooted in trauma, stress, relationships, identity, and emotional disconnection using compassionate, trauma-informed therapy approaches, including Internal Family Systems (IFS).

Frequently Asked Questions About IFS
Answers to the questions people most commonly ask when researching Internal Family Systems therapy.
Can IFS help with trauma or PTSD?
Yes. IFS is widely used for trauma and PTSD. A 2025 scoping review specifically highlights it as promising for post-traumatic stress. By gently unburdening Exiles that carry traumatic memories and calming Firefighters that drive impulsive coping, IFS can process trauma without forcing direct re-exposure to the event.
What is the difference between IFS and EMDR?
EMDR uses bilateral stimulation (eye movements or tapping) to help the brain reprocess traumatic memories. IFS accesses those same memories by dialoguing with internal Parts. They aren’t mutually exclusive — many clinicians use IFS to build internal stability before introducing EMDR, especially with complex trauma or dissociation.
What are the negatives or risks of IFS therapy?
IFS is not appropriate for people with schizophrenia or active psychosis, as encouraging inner ‘splitting’ can be disorganizing for those struggling with reality testing. The evidence base, while growing, is smaller than CBT or EMDR. Overapplication by practitioners without trauma-informed training is also a documented concern in the professional literature.
Are there books for learning IFS on your own?
“No Bad Parts” by Dr. Richard Schwartz (2021) is the most accessible self-help IFS book. For trauma-focused work, “Transcending Trauma” by Frank Anderson is highly recommended. Note that self-guided IFS can be helpful for general growth, but is not a substitute for working with a trained therapist when dealing with active trauma.
How is IFS different from CBT?
CBT focuses on identifying and restructuring maladaptive thoughts and behaviors. IFS works at the level of sub-personalities — understanding why parts developed their roles and healing the wounds they carry. CBT is more symptom-focused and directive; IFS is more exploratory and relationship-based (between Self and parts).
