What is IFS Therapy? A Simple Guide to Understanding Your "Parts"

By Amy Moran, LCPC, CST, PMH-C and Owner of Spark Chicago Therapy

Have you ever thought:

Part of me wants to leave this relationship, but another part desperately wants to stay.

Or:

I know my partner isn't rejecting me, but something in me immediately feels abandoned.

Congratulations! You have parts.

(We all do.)

Internal Family Systems (IFS) is a therapy model developed by Dr. Richard Schwartz based on the idea that our personalities aren't one singular, consistent voice. Instead, we all have different "parts" that developed to help us navigate our experiences, relationships, and, sometimes, painful things that happened to us.

So, What Exactly Is a “Part”?

Think about the part of you that gets defensive during an argument. The part that needs everything to be perfect. The people-pleaser. The part that wants reassurance from your partner RIGHT NOW. The part that shuts down and would prefer everyone leave you alone forever.

IFS doesn't view these reactions as evidence that something is wrong with you.

Instead, we get curious: What is this part trying to do for you?

Often, even our most frustrating behaviors developed for a reason.

Maybe your hyper-independent part learned early that relying on other people wasn't safe. Maybe your perfectionistic part figured out that making mistakes led to criticism. Maybe the part that panics when your partner pulls away remembers what it felt like to be abandoned long before this relationship existed.

IFS helps us understand the why underneath the behavior.

Managers, Firefighters, and Exiles (Oh My)

IFS generally describes three types of parts.

Managers try to prevent bad things from happening. They plan, control, perfect, people-please, worry, and anticipate.

Firefighters show up when distress is already happening and want it to STOP. NOW. They might shut down, lash out, drink, scroll, avoid, overeat, or do anything else that provides immediate relief.

And exiles are the vulnerable parts underneath it all—the ones carrying fear, shame, loneliness, rejection, or old wounds.

Your manager might spend years making sure nobody gets close enough to activate an exile. And when someone finally does? Hello, firefighter.

Where Does “Self” Come In?

IFS also proposes that underneath all these protective parts is your Self—the grounded, compassionate, curious version of you that can notice a reaction without immediately being consumed by it.

The goal isn't to get rid of your parts.

It's to understand them well enough that they don't have to run the show.

How We Use IFS at Spark Chicago Therapy

At Spark Chicago Therapy, IFS can be integrated into individual, relationship, trauma, and sex therapy alongside other therapeutic approaches. Our clinicians don't believe therapy is one-size-fits-all, so IFS is one tool we may use to understand what's happening underneath a pattern.

That might mean identifying the part that becomes terrified during conflict, the part that shuts down during sex, the part that can't stop seeking reassurance, or the part that knows a relationship isn't working but feels unable to leave.

Instead of asking, "Why am I like this?"

IFS encourages a much more useful question:

"What is this part of me trying to protect?"

And very often, that's where things start getting interesting.
