How they work
AEDP
Core mechanism: Undoing aloneness + affective experiencing of core emotions → transformance (innate healing drive) → metatherapeutic processing of change itself
Ontology: Aloneness in the face of overwhelming affect forces defensive exclusion of core emotional experience
Circle of Security
Core mechanism: Helping caregivers recognize and regulate their own triggered defensive responses (shark music) so they can remain present to their child's actual attachment needs on the Circle of Security: providing safe haven when the child needs comfort and secure base when the child needs to explore
Ontology: Child security develops through repeated experience of a caregiver who is bigger, stronger, wiser, and kind: present enough to provide safe haven and secure base, and capable of reflecting on their own triggered responses without being controlled by them.

What each assumes — and misses
AEDP
Philosophical roots: Davanloo and Malan (experiential short-term dynamic therapy, the lineage Fosha trained in; AEDP keeps the focus on defense and core affect but replaces confrontation with attunement); Winnicott (true self emerges in safety); Bowlby (attachment); Buber (I-Thou); Damasio (emotion as essential to reason); Fosha (transformance, an innate healing drive)
Blind spots: No controlled research; emphasis on positive affect can bypass necessary grief work; highly reliant on therapist skill
Therapeutic voice: Something just shifted in your face. Stay with that. What are you feeling right now, right here with me?
Circle of Security
Philosophical roots: Bowlby (attachment theory, safe haven and secure base); Ainsworth (Strange Situation, attachment patterns); Main (Adult Attachment Interview, reflective function); Winnicott (good enough mothering); Stern (attunement, intersubjectivity)
Blind spots: COS-P group protocol relies on DVD-based delivery which limits individualization; home visiting version requires significant training and supervision; not appropriate for active child abuse situations without additional safety planning; caregiver's own attachment trauma may require individual therapy beyond what COS provides
Therapeutic voice: Your child reached for you just then, and you pulled back. What were you feeling right at that moment? Not what you thought. What you felt.
Choosing between them
AEDP (Psychoanalytic) and Circle of Security (Family Systems) come from different traditions, which means they assume different things about what a person is, what causes suffering, and what the therapeutic relationship is for. The choice between them is often less about "which works better" and more about which set of assumptions fits the client and the therapist.
