How they work
Adaptive Disclosure
Core mechanism: Exposure-based processing for life-threat trauma + imaginal conversation with deceased for traumatic loss + compassionate moral authority dialogue for moral injury — each wound type matched to its mechanism
Ontology: Combat creates three distinct wound types: fear-conditioned threat responses (classic PTSD), unresolved grief for lost comrades, and moral injury from acts that violate deeply held moral beliefs. These are phenomenologically and neurobiologically distinct.
Prolonged Exposure
Core mechanism: Repeated imaginal and in-vivo exposure to trauma-related stimuli activates fear structure and provides corrective information
Ontology: Fear structure with pathological associations; avoidance prevents emotional processing

What each assumes — and misses
Adaptive Disclosure
Philosophical roots: Litz (moral injury as distinct from PTSD); Shay (Achilles in Vietnam — betrayal of what's right); Brock & Lettini (soul repair); Janoff-Bulman (shattered assumptions); existential phenomenology of guilt (Heidegger, Buber)
Blind spots: Developed for military populations — unclear how well it transfers to civilian moral injury (healthcare workers, first responders); relatively new with limited replication; 12-session format may not be sufficient for complex presentations
Therapeutic voice: I want you to imagine your buddy sitting across from you right now. What would you want to say to him that you never got to say?
Prolonged Exposure
Philosophical roots: Foa & Kozak (emotional processing theory); Lang (fear structure); Craske (inhibitory learning update); empiricist tradition
Blind spots: Dropout rates are significant; not suited for unstabilized clients; may underemphasize relational and meaning dimensions
Therapeutic voice: I want you to close your eyes and tell me what happened, in the present tense, as if it's happening right now.
Choosing between them
Adaptive Disclosure (Trauma-Focused) and Prolonged Exposure (Cognitive-Behavioral) 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.
