Internal Family Systems

No bad parts1

Every part has a positive intent, even when its actions cause harm; the aim is not to fight or remove parts.

Exiles1

Parts carrying pain, shame or fear from past trauma, kept out of awareness.

Managers1

Proactive protectors that try to keep exiles from being triggered by controlling life and relationships.

Firefighters1

Reactive protectors that douse pain once an exile breaks through, for example with substances, bingeing or dissociation.

The Self1

The natural leader, with eight qualities: compassion, curiosity, clarity, creativity, calm, confidence, courage and connectedness.

Managers5

Parts that keep someone from getting too close to or dependent on others, criticise their appearance or performance to make them look better, or focus on others' needs instead of their own.

Exiles5

Illustration: a part that still feels like the child who was laughed at in class and carries the belief "I'm not wanted"; managers keep it locked away so the shame does not surface.

Firefighters5

Illustration: after a harsh message from a boss stirs up an exile's shame, someone spends the evening drinking or bingeing on food to douse the feeling. Bingeing on drugs, alcohol, food, sex or work are common firefighter activities.

Polarized parts5

One client Schwartz describes had an ongoing inner war between a part that pushed her to achieve and a pessimist that told her it was hopeless.

A protector's positive intent5

When she asked the pessimist why it called her hopeless, it answered that it did so to stop her taking risks and getting hurt: it was trying to protect her.

Feeling toward a part1

Illustration: if a client says "I hate this part", the hate belongs to another blended part, which is asked to step back; curiosity or compassion is the sign of Self.

Stepping back5

The angry part agreed to step back, and the client shifted at once into a calm, caring voice: grateful to the pessimist for protecting her and sorry it had to work so hard.

What Self sounds like5

Asked which part was present in that calm state, clients answered: "That's not a part like those other voices are; that's more of who I really am -- that's my Self."

Unblending (the 6 Fs)1

Find, focus on, flesh out, feel toward, befriend, and ask what the part fears; if you feel anything but curiosity or compassion, another part is blended.

Protectors first1

Exiles are approached only with the protectors' permission; bypassing them can trigger backlash.

Healing an exile1

The Self witnesses the exile's story, reparents it in imagination, retrieves it from the past and helps it unburden.

Unburdening1

Painful beliefs and feelings are released, often imagined as going to fire, water, wind, earth or light.

Rheumatoid arthritis trial (2013)1

In 79 patients, IFS reduced pain and depression versus control, but not objective disease activity.

PTSD pilot (2021)1

92% of 17 completers no longer met PTSD criteria after 16 weeks, but there was no control group.

Scoping review (2025)1

Called it promising for PTSD, depression and chronic pain, and said larger rigorous studies are needed.

Criticism1

A 2025 New York Magazine report called it pseudoscientific and said rushed parts work can destabilise traumatised clients; the IFS Institute disputed this.

Spiritual add-ons1

Schwartz's later ideas of 'guides' and 'unattached burdens' go beyond the clinical model and are contested.
