What Is IFS Therapy? A guide to understanding your inner world

Internal Family Systems (IFS) is a therapy model that’s evidence-based, non-pathologising psychotherapy that views the mind as a system of distinct "parts" (sub-personalities), each with their own perspective, history, and protective role, led by a core, compassionate "Self". Rather than fighting or suppressing difficult thoughts and feelings, IFS works with them, finding out what they are protecting and helping the system heal from the inside. For many people, it is the first time therapy has felt like it fits how their mind works.

There is a particular kind of exhaustion that comes from trying to be consistent. You tell yourself you are going to do something differently, relate differently, respond differently, and stop the same loop from running, and for a while you do. Then something happens, and you are back where you started, wondering why understanding yourself has not been enough to change anything.

This is where most people find their way to Internal Family Systems therapy. Not because they have not tried. Because they have, and they are tired of trying in a way that keeps failing.

IFS was developed by Richard Schwartz in the 1980s, originally as a family systems approach, and has since become one of the most well-researched models in contemporary psychotherapy. A 2021 study published in the Journal of Rheumatology found significant reductions in pain, depression, and self-compassion scores among participants receiving IFS therapy, and research from institutions including Harvard Medical School has highlighted its effectiveness with complex trauma, shame, and chronic stress. But the reason it tends to resonate with people in a way that other models do not is less about the research and more about the map it offers.

The central idea in IFS is that the mind is not a single, unified thing. It is a system made up of multiple parts, each carrying its own feelings, beliefs, and ways of moving through the world. Some of those parts developed long before you had the language or the safety to make sense of what was happening to you. They learnt to protect you, whether that’s through anger, withdrawal, overachievement, numbing, people-pleasing, or even self-criticism; and they became very good at their jobs. So good, in fact, that they kept doing them long after the original situation had passed.

This is not pathology. It is intelligence. The parts that cause the most difficulty are usually the ones that worked the hardest to keep you safe.

In IFS, we distinguish between these protective parts and what Schwartz calls the Self: a core state of being that exists in every person and is characterised by curiosity, calm, clarity, and compassion. The Self is not something you build or earn. It is already there. The work of IFS is to help the protective parts trust it enough to step back so that the system can begin to heal rather than just manage.

What this looks like in a session is quieter than people expect. Rather than analysing a pattern from the outside, we turn towards it. We notice where a feeling lives in the body. We ask it what it wants us to know. We find out what it is afraid will happen if it stops doing what it does. In my experience, this is often the moment when something shifts, not because an insight has been reached, but because a part of the person has finally been heard rather than overridden.

Many of the people I work with have done therapy before, read widely, and understand themselves intellectually in considerable depth. What IFS offers is not more understanding but a different kind of contact with the parts of themselves that understanding alone has not been able to reach.

That is where Brainspotting often comes in alongside IFS. Developed by David Grand, Brainspotting works on the understanding that trauma and distress are held in specific locations in the brain's subcortical processing systems and that these locations can be accessed through fixed eye positions. In plain terms: where you look affects what you feel, and certain points of gaze allow the nervous system to process what it has not been able to release through talking or thinking. When a part of the system has been carrying something for a long time, Brainspotting can reach it in a way that conversation cannot. I sometimes use both approaches together because they work on different levels of the same system; IFS names and builds relationships with the parts; Brainspotting helps the body complete what the parts have been holding.

If you have tried to change something in yourself and found that you keep running into the same wall, IFS may offer something different. Not a technique to apply to yourself, but a way of meeting yourself that you may not have been offered before.
