If you’ve heard the phrase “parts work” or Internal Family Systems (IFS) and wondered what it actually looks like in therapy, you’re not alone. Many people arrive in my (or any) office saying something like:

“I know I have different parts of me that fight with each other… but is that normal?”

IFS starts from the assumption that yes, it is normal. Your inner life is made up of many “parts,” versions of you that hold different emotions, needs, and strategies for getting through life. Rather than trying to get rid of parts, IFS helps them relax, heal, and work together.

This post will walk you through:

1. What IFS is (in everyday language)
2. What conditions it can help with, and what the research shows
3. What a typical IFS session is like

What is Internal Family Systems (IFS)?

IFS is a form of psychotherapy developed by Dr. Richard Schwartz in the 1980s. PubMed+1 It combines ideas from family therapy with the observation that our inner worlds also behave like a “family,” sometimes loving and cooperative, sometimes chaotic and overwhelmed.

The core ideas of IFS

IFS rests on a few key principles:

• We all have “parts.”
  These are subpersonalities or “inner people;” like the Perfectionist, the Planner, the Angry Teen, the Worried One, the Numb One, the Overachiever, and so on.
• Every part has a positive intention.
  Even the parts that use extreme strategies (self-criticism, numbing, overworking, bingeing, anger, shutdown) are trying to protect you from pain or help you function.
• We all have a core “Self.”
  Self is the calm, steady, compassionate center of who you are. When Self is leading, you tend to feel more curious, grounded, confident, and connected. In IFS we often talk about the “8 C’s” of Self: calm, curious, compassionate, connected, confident, courageous, clear, and creative.
• Healing happens when Self is in the lead and parts are heard, understood, and unburdened.
  Instead of fighting with parts (“I hate my anxiety”), IFS helps you build a relationship with them.

The three main types of parts

IFS often describes three broad categories of parts:

1. Exiles
   • These are young or vulnerable parts that carry pain, shame, fear, grief, or loneliness; often linked to earlier experiences (including trauma, bullying, misattunement, or major life stress).
   • Because their feelings can be intense, other parts work hard to keep them out of awareness.
2. Managers
   • These parts try to prevent hurt and chaos before it happens.
   • They might push you to perform, over-prepare, people-please, “stay small,” stay hyper-vigilant, or keep emotions tightly controlled.
3. Firefighters
   • These parts jump in when pain breaks through anyway.
   • They’re focused on putting out emotional fires now, sometimes through numbing behaviors (scrolling, food, substances, overworking, staying in bed, angry outbursts, self-harm urges, etc.).

In IFS, the aim is not to get rid of managers or firefighters, or to force exiles to “get over it.” Instead, the therapist helps you build trust with these parts, understand what they’re protecting, and then gently heal the burdens they’ve been carrying so they don’t have to work so hard.

What Can IFS Help With? (And What Does the Research Say?)

IFS has become very popular, sometimes faster than the research can keep up. The current evidence base is promising but still emerging, which is important to say out loud. A 2025 scoping review found that IFS shows encouraging results for conditions like chronic pain, depression, and PTSD, but also noted that there are still relatively few rigorous studies for such a widely used model.

Here’s a snapshot of what studies so far suggest:

Rheumatoid arthritis, chronic pain, and mood

One of the earliest randomized controlled trials of IFS looked at people with rheumatoid arthritis. Participants who received an IFS-based group intervention showed:

• Reduced pain
• Reduced depressive symptoms
• Improved physical functioning

The authors concluded that IFS was feasible and acceptable and might complement medical treatment for rheumatoid arthritis.

PTSD and complex trauma

More recent work has focused on trauma:

• A pilot study of adults with PTSD and histories of multiple forms of childhood trauma found that IFS significantly reduced PTSD and depressive symptoms, with 92% of participants no longer meeting criteria for PTSD at one-month follow-up.
• A 2025 pilot of an online, group-based IFS program for people with both PTSD and substance use disorders found the approach feasible and acceptable, with improvements in PTSD symptoms and emotion regulation.

This is particularly relevant if you’re navigating complex trauma, chronic hypervigilance, or long-standing patterns that feel “stuck.” IFS is designed to work with layered, protective systems like that.

Depression, anxiety, and trauma-related symptoms

Several studies and clinical reports suggest that IFS can help with:

• Depressive symptoms
• Anxiety and anxiety sensitivity
• Body-related distress (like body dysphoria) in people with trauma histories
• Overall emotional regulation and self-compassion

IFS, psychedelics, and other contexts

Some emerging research is exploring IFS as a framework for psychedelic-assisted treatment, where the “parts” lens may help people navigate powerful inner experiences.

A realistic, transparent view

It’s important to be honest: compared to therapies like CBT or EMDR, IFS still has a relatively small number of large randomized trials. Professional organizations describe it as a promising, non-pathologizing, evidence-informed model, while also calling for more rigorous research.

So if you choose IFS, you’re choosing an approach that:

• Aligns well with trauma-assumed and neurodivergent-affirming care (because it honors all parts of you and doesn’t frame your adaptations as “bad”),
• Has growing research support, especially for trauma and chronic conditions,
• And is still building its evidence base over time.

How IFS Fits People With Complex Trauma, ADHD, and Neurodivergence

Many clients who feel “too much,” “too sensitive,” “too scattered,” or “too defended” find relief in the IFS frame. It normalizes having multiple inner voices and emotional states instead of treating that as a problem.

IFS can be especially supportive if you:

• Have complex trauma or a trauma history that doesn’t fit neatly into one event
• Live with ADHD, autistic traits, or other forms of neurodivergence, and feel like parts of you are constantly at war (e.g., one part wants routines, another seeks novelty, another shuts down from overwhelm)
• Struggle with shame, self-criticism, perfectionism, or burnout
• Swing between over-functioning and collapse

IFS helps you notice: “Oh, this isn’t all of me; this is a part of me that learned to protect me.” That shift alone can create space for genuine change.

What Does an IFS Session Actually Look Like?

You don’t have to come to an IFS session knowing your parts or using special language. Your therapist will help you map that out together.

Every therapist has their own style, but here’s a general sense of what a session may involve.

1. Settling in and orienting

We usually begin by checking in:

• How have you been since we last met?
• Any particular situations or reactions standing out?
• Is there a specific part or pattern you’d like to focus on today (e.g., your inner critic, a shutdown response, a bingeing part, a panicky part)?

We may spend a few minutes grounding — noticing the room, your breath, your contact with the chair — so your nervous system has some sense of safety before we go inward.

2. Choosing a starting point: a part or a situation

Together we pick a starting point for “parts work,” which might be:

• A recurring behavior (“The part that procrastinates until 2 a.m.”)
• A feeling (“The anxious knot in my chest when my partner looks upset”)
• A body sensation (“The heavy, frozen feeling before I open my email”)
• A specific situation (“The way I went numb in that work meeting”)

The therapist may ask for your permission to get curious about the part that shows up in that moment.

3. Getting to know a part — from Self

IFS therapy is always trying to support more Self-leadership. So instead of the therapist “analyzing” your part, they guide you to get to know it.

This can sound like:

• “As you notice that anxious part, how do you feel toward it?”
• “Is there any other part that has strong feelings about us focusing on this one right now?”
• “If you check inside, where do you sense this part in or around your body?”

You might notice images, words, body sensations, memories, or just a vague sense of a presence. There’s no right way to experience a part.

The therapist will help you move from reactions like “I hate this part” or “I just want it gone” toward more Self-energy: curiosity, compassion, and calm. We don’t force that; we respect that other protective parts might need attention first.

4. Listening to what the part is trying to do for you

Once a part feels safe enough to be “in the room” with you, we get curious about its job:

• What is it afraid would happen if it didn’t act this way?
• When did it first take on this role?
• How old does it feel?
• What does it wish you knew?

Often, managers and firefighters reveal that they’ve been working overtime for years or decades. They may be trying to keep you from feeling exiled pain: the part who felt humiliated in 3rd grade, the kid who tried to keep the peace during parental conflict, the teenager who had to go numb to get through.

5. Meeting and healing exiles (when it’s safe enough)

IFS is careful about pacing. We don’t go straight to the most painful memories without permission from your protective parts.

When protectors are willing, you may:

• Turn toward a younger or more vulnerable part (an exile) that carries pain
• Witness what that part went through, from the steadier perspective of Self
• Offer the support, protection, or understanding that wasn’t available at the time

Over time, exiles can “unburden” the beliefs and emotions they’ve been carrying, such as:

• “It was my fault.”
• “I’m too much.”
• “I’m unsafe everywhere.”
• “I always ruin things.”

The image of unburdening is sometimes literal in your imagination: giving something heavy back, burning it, washing it away, or letting it float down a river. Your internal system usually finds its own symbols.

6. Updating the system

Once an exile has released some of its burden, protectors often don’t have to work so hard. The therapist might ask:

• How do your manager parts feel now, knowing this younger part is no longer alone with that pain?
• Are they willing to try a less extreme role — maybe still helping you, but with more flexibility?

The goal is internal cooperation: protectors feel respected, exiles feel cared for, and Self is more in charge.

7. Closing and integration

Before ending, we usually:

• Check in with the parts we met: what do they need between now and next time?
• Help you come back to the present by noticing the room, your body, and anything that feels grounding
• Clarify any “homework” if that fits for you — often gentle things like noticing when a specific part shows up and how you respond to it, or journaling from the perspective of a part if that feels supportive

What You Might Feel in an IFS Session

Clients often say that IFS feels:

• Collaborative: You’re not being “interpreted”; you’re learning to be with your own inner world with the therapist’s support.
• Non-shaming: Even your most extreme reactions make sense in context.
• Surprisingly practical: Once you know your parts, it becomes easier to catch patterns in everyday life ; “Ah, my Perfectionist is in charge right now.”
• Sometimes emotional, sometimes spacious: Some sessions are intense and tender; others focus on mapping the system, resourcing, or building trust with protectors.

It’s also normal to feel unsure at first:

• “Am I making this up?”
• “What if I don’t see images or hear inner voices?”
• “What if I have so many parts I lose track?”

Your therapist’s job is to normalize these reactions and adjust the pace. Some people experience parts as clear images or characters; others feel them mainly as body sensations, moods, or “knowing.” All of that is welcome.

Is IFS Right for You?

IFS might be a good fit if you:

• Notice strong inner critics, perfectionism, or shame
• Find yourself swinging between over-control and “I don’t care anymore”
• Have trauma or chronic stress that shows up in your body and relationships
• Feel like different parts of you want opposite things (connection vs. isolation, visibility vs. hiding, rest vs. overwork)
• Want an approach that respects your protective strategies instead of pathologizing them

IFS can usually be integrated with other approaches, too — like EMDR, CBT, DBT skills, or somatic work. Many therapists blend them thoughtfully, especially for complex trauma and neurodivergent clients.

A Note on Safety and Scope

IFS may not be the best stand-alone fit for every situation. People who are acutely psychotic, extremely ungrounded, or struggling with reality testing may need different or additional forms of care.

If you’re unsure, that’s something to discuss openly with your therapist. A good clinician will be transparent about their training, how they use IFS, and how they monitor for safety.

If You’re Curious About Starting

If this way of thinking about your inner world resonates — if you can feel that there are different parts of you, and you’d like a kinder way to relate to them — IFS can offer a structured, research-informed, and compassionate path.

You don’t have to have it all figured out before you begin. You just have to bring yourself, as you are, and we’ll meet your parts at a pace that feels manageable for your system.
