Overview

Internal family systems therapy (IFS) is form of talking therapy that is used to address a wide variety of difficulties (Schwartz & Sweezy, 2019; Anderson et al., 2017). It is based on the idea that the mind consists of distinct subpersonalities, or ‘parts,’ each with its own perspectives, interests, memories, and bodily sensations. These parts interact with one another, which can sometimes lead to conflicts, polarisation, and emotional distress. The What Is Internal Family Systems (IFS) Therapy? information handout is designed to introduce clients to IFS. It provides an overview of key concepts and the tasks involved in the therapy.

Theoretical Background & Therapist Guidance

Internal family systems (IFS) therapy, developed by Richard Schwartz in the 1980s, is based on the idea that the mind is made up of distinct “parts,” each with its own emotions, perspectives, and memories. Like members of a family, these parts can sometimes clash, creating inner conflict and distress. Alongside these parts, every person also has a “Self” that can guide healing when accessed.

Parts are grouped into protectors and exiles. Protectors work to shield us from pain. Exiles, on the other hand, are vulnerable parts that carry the burdens of trauma, shame, or fear and long for care and acceptance. In IFS, the aim is not to suppress or eliminate parts, but to understand and care for them, guided by the Self.

IFS differs from many therapies in that it views all parts as valuable and well-intentioned, rather than dysfunctional. Healing does not come from the therapist but from the client’s Self, which exists independently of life experiences. Unlike structured, diagnostic approaches, IFS is process-driven, beginning with whichever part arises and trusting clarity and healing will emerge. It is also open to the possibility of developing spiritual connection, though this is not required for therapeutic benefit.
