How they work
Attachment-Focused EMDR
Core mechanism: Bilateral stimulation within an attuned relational context activates the attachment system while processing early wounds, enabling internalization of a secure base through both the therapeutic relationship and imaginal resource figures
Ontology: The self as shaped by early relational deficits — not primarily by discrete traumatic events but by chronic failures of attunement — that require both trauma processing and relational repair
IFS
Core mechanism: Self-energy (curiosity, compassion, calm) accesses and unburdenes exiled parts; protector parts relax when exiles are healed
Ontology: Internal system of parts carrying burdens from attachment injuries; protectors manage exiles' pain

What each assumes — and misses
Attachment-Focused EMDR
Philosophical roots: Bowlby (attachment theory); Ainsworth (secure base); Main (disorganized attachment); Winnicott (good enough mother); Siegel (interpersonal neurobiology)
Blind spots: Limited independent research base; departure from standard EMDR fidelity raises questions for purists; requires both EMDR and attachment theory competence; some modifications not empirically validated independently
Therapeutic voice: Let's bring in your nurturing figure. Can you feel their presence with you? Stay with that, and follow the taps.
IFS
Philosophical roots: Systems theory (Bertalanffy); Schwartz (inner system as family); Jung (subpersonalities, Self); Buddhist concept of witnessing awareness (Self-energy); multiplicity of mind (Ornstein, Minsky)
Blind spots: Popularity far outpaces evidence base; parts language can become reified; limited research outside pilot studies
Therapeutic voice: Can you ask that critical part what it's afraid would happen if it stepped back?
Choosing between them
Attachment-Focused EMDR (Trauma-Focused) and IFS (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.
