He found that the inner world of all his clients was characterized by parts who had a positive intent for the client but had taken on extreme roles in an effort to be safe. He also discovered that these extreme parts would become less disruptive and more cooperative once their concerns were addressed and they felt safer. IFS views psychic multiplicity as the norm: we all have parts. In addition, every part has a good intention for the client, and every part has value. When clients listen to all their parts, they can heal their wounded parts. Today, IFS, which has established a legacy of efficiency and effectiveness in treating many mental health issues, is being heralded by Dr. Bessel van der Kolk as a treatment that all clinicians should know.
