Course Description

This is a THEORY-forward course presented by Diana Fosha, PhD, developer of AEDP psychotherapy and founder and director of the AEDP Institute.

Twenty-one years after the publication of her 1st book, The Transforming Power of Affect, the book that launched AEDP, there is a new book on the model. The new book, titled “Undoing Aloneness & The Transformation of Suffering into Flourishing: AEDP 2.0 (APA, 2021)” which came out in the summer of 2021, features the latest thinking on AEDP psychotherapy’s theory and practice; it is a book that Diana and her Institute Faculty colleagues fondly refer to as the “AEDP 2.0” book.

The latest thinking in AEDP theory and practice”, is, in essence, what this, Diana’s online 9 +1 course -with its focus on AEDP’s affective change processes- is about.

Naturally occurring, adaptive, affective change processes have always been at the heart of AEDP’s healing oriented, radically relational, transformational practice. In the two decades between the two books, the clinical, practice-based theory of AEDP has grown, expanded, and deepened. And it has been put to the test hundreds of thousands of times worldwide in transformational moments between patients and us, their AEDP therapists, worldwide.

In addition, empirical support on the effectiveness of AEDP has also arrived on the scene. The need to systematize, codify and measure both outcome and process in AEDP therapy sessions has led to the development of a number of AEDP Scales. Amongst them is what we have come to call “The Magnificent 9 +1 Affective Change Processes Scale,” developed by Diana Fosha and codified with her AEDP Research Team colleagues, Jennifer Edlin, MFT and Shigeru Iwakabe, PhD. This scale describes what makes AEDP AEDP: it attempts to capture the processes that make AEDP effective for so many patients. These AEDP affective change processes provide the scaffolding for exploring AEDP 2.0 theory and clinical practice in this online course that Diana is teaching.

Unlike many of the other AEDP courses that have a strong experiential component, this 9+1 course will focus on the theory underlying AEDP’s clinical practice.

Through assigned readings; didactic presentations; clinical video from Diana Fosha and her guest presenters’ actual clinical sessions; in class discussion (as well as optional study group discussion), participants will deepen their understanding of the theory of AEDP, in a way that will add depth and precision to their clinical practice.

In a series of thirteen 3-hour online classes from January – June, 2023 Diana will elaborate AEDP 2.0’s theory and clinical framework organized around AEDP’s Magnificent ‘9 + 1’ Affective Change Processes.

What to Expect in the Thirteen Sessions


Participants will be expected to complete readings for each session, in addition to attending all 13 live sessions. There is a lot of reading..

READING GROUPS and COURSE LISTSERV: Not required, but we strongly suggest that participants meet with a “reading group” in the off weeks between class sessions. Reading groups will not be monitored and there are no CE’s given for this time. Participants will be asked to form and maintain reading groups largely on their own. The course will have its own listserv for additional course discussion and for communicating needs around meeting with reading groups.

Topics and Format of each Session:

Each session will consist of a mix of (i) didactic presentation and discussion of the readings; (ii) showing and discussing clinical tape relevant to that topic; and integrative discussions with fellow AEDPers, some in breakout rooms and some led by Diana in the main room.
