What Is Internal Family Systems (IFS) Therapy?
If you've ever caught yourself thinking "part of me wants this, but another part of me is terrified of it" — you've already brushed up against the core idea behind Internal Family Systems therapy, even if you've never heard the name.
Internal Family Systems (commonly shortened to IFS) is an evidence-based psychotherapy model developed by psychologist Dr Richard Schwartz in the 1980s. It starts from a simple, almost obvious observation once you sit with it: the human mind is naturally plural. You're not one single, unified voice — you're made up of many different "parts," each with its own feelings, fears, and ways of trying to protect you.
This article breaks down what IFS actually is, how it works, and what it can offer you — in plain language, not clinical jargon.
The Basic Idea: You Contain Multitudes
Most of us already talk this way without realising it's a clinical framework. "Part of me wants to leave this job, but another part is scared of starting over." "One part of me knows I should rest, but another part won't let me stop working." IFS takes this everyday language seriously, rather than dismissing it as just a figure of speech.
IFS views psychological distress as the result of extreme roles taken on by otherwise well-intentioned protective parts — parts that were doing their best with the situation they had, even if the way they're protecting you now causes its own problems. Within this model, your parts generally fall into a few recognisable roles:
- Exiles — the most vulnerable parts, carrying past pain, trauma, or shame. These are often the youngest, most tender parts of you, frequently formed in childhood.
- Managers — proactive protective parts that try to keep you safe and organised, often by staying busy, striving, or avoiding anything that might stir up an Exile's pain.
- Firefighters — reactive protective parts that act to extinguish distress once it's already broken through, often reaching for distraction, numbing, or intensity to put the fire out fast.
None of these parts are "bad" or something to get rid of. Each one developed for a reason, usually to protect you at a time when you genuinely needed protecting.
The Self: Who's Actually Running the Show
Underneath all of these parts, IFS proposes there's a core "Self" — fundamentally undamaged, no matter what you've been through. IFS describes this Self through eight qualities, often called the 8 Cs: calmness, curiosity, clarity, compassion, confidence, courage, creativity, and connectedness.
The goal of IFS therapy isn't to fight your parts or force them into silence. It's to help your Self come back into a leadership role, so your parts can trust that someone stable is actually in charge. This is why IFS therapy is structured around facilitating self-led healing rather than eliminating parts.
What Actually Happens in an IFS Session
A skilled IFS therapist guides you to explore your own internal experience with curiosity and compassion, rather than judgment — building a genuine dialogue between your Self and your various parts, so they can start to communicate and trust each other instead of working against one another.
In practice, this often looks like slowing down enough to actually notice a part — the tight chest before a hard conversation, the urge to scroll your phone the second something uncomfortable comes up, the harsh inner voice that shows up after a mistake — and getting curious about it instead of trying to push it away.
Over time, this process aims to heal emotional wounds by unburdening Exiles — helping those vulnerable, wounded parts finally release the pain, beliefs, or fear they've been carrying, often for decades.
Does IFS Actually Work?
Being upfront here matters to me: research on IFS is genuinely promising, particularly for depression and PTSD, but it's still a developing evidence base. I think it's more honest to say that clearly than to oversell it.
One notable early result: seventeen adults with PTSD and histories of multiple childhood trauma enrolled in a pilot study; of the 13 who completed the full 16-session protocol, 12 — 92% — no longer met the criteria for PTSD at one-month follow-up (Hodgdon, H. B., Anderson, F. G., Southwell, E., Hrubec, W., & Schwartz, R. (2022). Internal Family Systems (IFS) Therapy for Posttraumatic Stress Disorder (PTSD) Among Survivors of Multiple Childhood Trauma: A Pilot Effectiveness Study. Journal of Aggression, Maltreatment & Trauma, 31(1), 22–43). That's a striking result, but it's worth being precise about what it is: a small pilot study, not a large randomised controlled trial. A separate randomised controlled trial found IFS-based work also improved pain, depression, and physical function for people with rheumatoid arthritis.
How I Bring IFS Into My Work
I'm IFS Level 1 trained (IFS Institute, 90-hour program), and I have completed my 'Somatic IFS' certificate with Susan McConnell — which brings the body directly into this process, since parts don't just show up as thoughts, they show up as physical sensations too. I integrate this alongside Relational Life Therapy, a broader trauma-informed, systemic approach, and a culturally attuned lens informed by my own bicultural, Asian-Australian and immigrant experience.
You can find my IFS training listing on the IFS UK Practitioner Directory, my profile on Psychology Today , and my listing on Shapes & Sounds, a directory for the Asian community's mental health.
If any of this resonates — the sense of being pulled in different directions internally, or wanting a gentler way to work with the parts of yourself that feel hardest to like — this is exactly the kind of work I do with individuals and couples.
