Internal Family Systems Therapy: What It's Like

Internal Family Systems, usually shortened to IFS and often called parts work, has quietly become one of the most talked-about approaches in therapy. Its central image, that the mind is made up of many parts, each with its own role and feelings, has resonated widely. For people who have felt at war with themselves, it offers a strikingly compassionate way of understanding the inner world.

This is a companion piece for people curious about IFS. It is not medical advice. It is an honest look at what it is and what working this way is like, and it is no substitute for working with a trained therapist.

The idea of parts

IFS proposes that we all contain a number of inner parts, sub-personalities that carry different emotions, memories, and protective roles. There might be an anxious part, a critical part, a part that pushes us to achieve, and parts that hold old pain. Crucially, IFS holds that beneath these parts each person has a core Self that is calm, curious, and compassionate. The work involves getting to know the parts rather than fighting them, including the ones that seem troublesome. People often find this framework intuitive, a language for the inner conflicts our companion piece on living with anxiety touches on.

What the work is like

In practice, IFS involves turning attention inward, with the therapist's guidance, to notice and become curious about a part: what it feels, what it fears, what it is trying to do for you. A key principle is that even parts that cause problems, such as harsh self-criticism or compulsive behaviours, are usually trying to protect us in some way, often because of past hurt. People describe the experience as gentle and non-judgemental, sometimes surprisingly moving, as parts that have felt burdened for years are heard and, in the language of IFS, unburdened. It can be especially relevant to trauma, which our companion piece on PTSD and trauma therapy explores.

What people find in it

People drawn to IFS often describe a shift from self-criticism to self-compassion, and from feeling divided to feeling more integrated. Understanding a part that drives overwork, for example, can ease the burnout our companion piece on burnout recovery describes. As with any therapy, people stress the importance of a properly trained therapist, note that it may not suit everyone, and observe that exploring painful parts can be intense. It is a process rather than a quick fix. None of this is a prescription for you; it is the ground others have walked with professional support.

A kinder inner conversation

What many value most in IFS is the kindness at its heart: the idea that there are no bad parts, only parts carrying burdens, and that healing comes through understanding rather than war. For people exhausted by their own inner critics, that reframing can be a relief in itself. It offers, at its best, a more peaceful relationship with one's own mind.
