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.
