Primal Integration (PI) is a form of personal growth work first formulated by the Canadian Bill Swartley in the mid-1970s. Unlike many other approaches known as psychotherapy, it puts the emphasis on an individual's self-directed exploration of their own psyche assisted by facilitators who serve the individual and are responsible for their safety. It uses an educational model and is considered to be part of humanistic psychology. It has a different approach to the better known Primal therapy formulated by Arthur Janov and is not related to it except in the broadest sense by its name and by its acceptance of the significance of early foetal experiences.
