Internal family systems therapy, or IFS, is one of the fastest growing models of psychotherapy today. Focused on psychic multiplicity and the healing effects of compassion, this non-pathologizing therapy has been adopted by clinicians around the world. Internal Family Systems Therapy builds on Richard Schwartz’s foundational introductory texts, illustrating how the IFS protocol can be applied to a variety of therapy modalities and patient populations. Each chapter provides clear, practical guidance and clinical illustrations. While addressing questions from therapists who are exploring the model or wonder about its applicability, Internal Family Systems Therapy is also essential reading for knowledgeable IFS clinicians.
