Therapeutic schools have a tendency to multiply. The IEDTA was founded in part to bring together proponents and practitioners of a range of EDTs. In some sense, there are as many varieties of EDTs as there are EDT practitioners, because every therapist must develop their own authentic style of practice. Some of the “flavors” of EDT that have been formalized in books, articles, or trainings are noted below, with links to additional information.
AET refines the time-tested ways people connect with one another in order to make them conscious and powerful. Both therapist and patient begin to recognize weak as well as strong body sensations. We learn our own unique triggers and how to read our bodies from moment to moment.
Accelerated Experiential Dynamic Psychotherapy (AEDP), developed by Diana Fosha, is a transformation-based, healing-oriented model of treatment. Unlike traditional models of therapy that are psychopathology-based, AEDP as a clinical practice roots itself in transformational theory, a change-based theory of therapeutic action.
APT was developed by Leigh McCullough, and integrates aspects of Davanloo's ISTDP with learning theory and the affect theory of Silvan Tomkins.
Robert Neborsky's AB-ISTDP applies the clinical insights and techniques of Davanloo's ISTDP, informed by research on attachment and emotion regulation.
DEFT was developed by Susan Warren Warshow utilizing carefully crafted, shame-sensitive interventions that convey compassion through verbal and embodied responses. These aim to most effectively regulate and transcend inhibitory and defensive affects and self-hurting defenses.
IEDP was developed by Ferruccio Osimo. This model has a unique emphasis on explicit exploration of the real relationship between therapist and patient, as a basis on which therapeutic techniques can build.
Habib Davanloo's ISTDP was a groundbreaking departure from previous short-term dynamic therapies because of its strong emphasis on the experience of deep emotion. All the other EDTs described here derive from it, at least historically.
Jeffrey Magnavita developed this model of therapy which focuses on interacting systems ranging from the biological-intrapsychic to the sociocultural-familial.
