AEDP affective change processes provide the scaffolding for AEDP clinical practice and transformational theory.
Training Description
AEDP has always been a multifaceted transformational therapy. Naturally occurring, adaptive, affective change processes have always been at the heart of AEDP Psychotherapy’s healing oriented, radically relational, dyadically experiential transformational practice. These discrete AEDP affective change processes provide the scaffolding for AEDP clinical practice and transformational theory. They in essence operationalize and account for how change takes place in AEDP Psychotherapy. Furthermore the clinical, practice-based theory of AEDP has also grown: It has expanded, deepened and been put to the test hundreds of thousands of times in transformational moments between patients and us, their AEDP therapists, worldwide.
With the advent of empirical research into AEDP Psychotherapy effectiveness (DiCorcia et al., 2022; Iwakabe et al, 2020; Iwakabe et al., 2022; Notsu et al., 2022), the need to systematize, codify and measure outcome and process in AEDP psychotherapy has led to the development of what we have come to call The Magnificent 9 +1 Affective Change Processes Scale. This scale, also evolving, attempts to capture what makes AEDP so effective for so many patients.
This course explores 9 affective change processes specific to AEDP, as well as the mystery factor, the “+1”. The 9 affective change processes are: i. Transformance detection & affirmation of the self; ii. Noticing & seizing a moment of emergence; iii. Undoing aloneness; iv. Experiential focus; v. Disarming defenses; vi. Working to regulate dysregulated experience; vii. Experientially processing core affective experience, aiming toward a corrective emotional experience; viii. The broadening & building of transformational experience, i.e., metatherapeutic processing; ix. Expanding core state experiences and the integration of transformation into self.
In keeping with the AEDP model: from experience comes insight and meaning. Insight and meaning are incredibly important and indeed transformational, however, understanding follows from experience. This is an opportunity to reflect and integrate and experience (via the realization affects) that a new and deeper understanding has the potential to re-organize everything that came before it, and thus can lead to more rounds of the transformational spiral.

OBJECTIVES
- Analyze how AEDP’s transformational theory is operationalized through each component of the Magnificent 9 + 1 Affective Change Processes Scale.
- Apply the definitions of all nine affective change processes and the “+1” factor to the conceptualization of clinical material.
- Demonstrate at least one change-process specific intervention for each of the nine affective change processes.
- Evaluate how empirical research into AEDP psychotherapy effectiveness has shaped the development and clinical application of the Magnificent 9 + 1 Affective Change Processes Scale.
- Differentiate among the five subcategories of affective change process #VII, with particular attention to experiential work with SELF experience and dynamically significant autobiographical unfolding.
- Apply change-process specific interventions in clinical role play, using the 9 + 1 Scale to organize and guide therapeutic decision-making.
- Evaluate their own clinical work using the Magnificent 9 + 1 Affective Change Processes Scale to identify areas of strength and targets for further skill development.
- Demonstrate how metatherapeutic processing can be used to deepen transformation and facilitate the integration of new experience into the patient’s sense of self.
- Construct a personal plan for integrating the Magnificent 9 + 1 Affective Change Processes Scale into their ongoing clinical practice with AEDP patients.

The AEDP® Model of Psychotherapy
The following statements describe the empirical foundation, accuracy, utility, scope, limitations, and clinical considerations relevant to the content presented in AEDP Courses.
Empirical Basis
AEDP® Psychotherapy is supported by peer-reviewed empirical research published in established scholarly journals. Effectiveness studies conducted within a practice research network demonstrate significant symptom reduction (e.g., depression, maladaptive negative cognitions, interpersonal functioning, experiential avoidance) and significant increases in positive indices of mental health (e.g., self-compassion, flourishing) across diagnostic presentations (Iwakabe et al., 2020), with longitudinal follow-up findings indicating maintenance of gains at six and twelve months (Iwakabe et al., 2022). These outcome studies evaluated a 16-session AEDP treatment protocol.
Additional empirical investigations examine therapeutic process variables associated with flourishing and metatherapeutic processing (Fosha & Thoma, 2020; Fosha, Thoma, & Yeung, 2019), as well as psychometric validation of measures assessing positive affective transformation, including the Moments of Flourishing Experience Scale (Fosha et al., 2024). Collectively, this body of outcome and process research provides empirical support for the clinical principles and interventions taught in AEDP Courses.
Accuracy, Utility, Scope and Limitations
AEDP is a transdiagnostic, transformation-oriented model of psychotherapy practiced with clients experiencing a wide range of psychological difficulties. Developed and primarily taught for individual psychotherapy, the model may be adapted by trained clinicians for work with couples, families, children, and groups when clinically appropriate; however, formal empirical research has focused primarily on its application in individual treatment.
AEDP was developed to address affective, relational, trauma-related, and depressive symptom presentations within an attachment-based, experiential framework. The empirical base is strongest for these domains, and findings from the 16-session research protocol should not be assumed to generalize automatically to all treatment formats, durations, or to individuals with severe or unstable psychiatric conditions.
AEDP was not designed as a first-line or stand-alone treatment for active psychotic disorders, bipolar disorder that is not medically stabilized, or active substance use disorders. In such cases, clinicians should ensure appropriate stabilization and integration with disorder-specific and medically coordinated care. As with all clinical models, effective application requires sound professional judgment, adherence to ethical standards, and practice within one’s scope of competence.
Ongoing Research
Current research continues to investigate the therapeutic processes and specific AEDP interventions associated with transformational change. In addition, AEDP-informed psychotherapy is being studied in collaboration with the Icahn School of Medicine at Mount Sinai within randomized controlled trials (RCTs) of psychedelic-assisted psychotherapy.
Risks and Clinical Considerations
As with all experiential and trauma-focused psychotherapies, potential risks include temporary increases in emotional distress, activation of traumatic memories, heightened affective arousal, interpersonal sensitivity, or destabilization if interventions are misapplied or insufficiently titrated. Severe risks are uncommon but may include significant dysregulation in vulnerable individuals if adequate screening, stabilization, and monitoring are not conducted. The model emphasizes careful attunement, pacing, and ongoing assessment to mitigate these risks.

Diana Fosha, PhD, is the developer of AEDP™ psychotherapy, a healing-based, transformation-oriented treatment model. And she is Founder and Director of the AEDP Institute. For the last 20 years, Diana has been active in promoting a scientific basis for a healing-oriented, attachment-emotion-transformation focused trauma treatment model. Fosha’s work focuses on integrating positive neuroplasticity, recognition science and developmental dyadic research into experiential and transformational clinical work with patients. Her most recent work focuses on promoting flourishing as a seamless part of the AEDP therapeutic process of transforming emotional suffering. Drawing on affective neuroscience, attachment theory, mother-infant developmental research, and research documenting the undreamed-of plasticity in the adult brain, AEDP is an experiential clinical practice which reflects the integration of science,research and practice in psychotherapy.

Institute Sponsored Courses Including Immersion, Essential Skills, Advanced Skill Modules, Seminars/Webinars and Institute Sponsored Core Trainings
The AEDP Institute does not offer make-ups for missed course days. In the rare case where someone joins a course late, or misses a session in the middle of a course, the hour(s) or day(s) that person misses cannot be made up. Why? Group dynamics developed during a course are essential to the course’s success; so someone coming into a course for a short period of time is – regardless of their best intentions – disruptive to other participants and the course’s overall success. The Institute will, however, provide handouts from missed hours or days but will not allow a person to make up the hours or days they miss in another course.
AEDP Level credit: if a participant attends 80% or more of a course, the Institute will apply the course towards AEDP Level advancement
