How they work
CPT
Core mechanism: Identifying and challenging stuck points (distorted trauma-related beliefs) restores balanced appraisals of safety, trust, power, esteem, intimacy
Ontology: Trauma disrupts pre-existing beliefs or generates distorted accommodations about self and world
Written Exposure Therapy
Core mechanism: Brief written exposure to trauma memory without homework or processing produces habituation and cognitive change (proposed)
Ontology: Same fear structure model as PE; written narrative activates and modifies trauma memory

What each assumes — and misses
CPT
Philosophical roots: Beck (cognitive model); Horowitz (stress response theory); Piaget (accommodation/assimilation); constructivism (meaning is actively constructed)
Blind spots: Cognitive focus may underemphasize somatic and emotional processing; structured protocol can feel rigid
Therapeutic voice: You wrote that the assault was your fault because you didn't fight back. Let's look at that stuck point together.
Written Exposure Therapy
Philosophical roots: Same theoretical base as PE (Foa — emotional processing); Pennebaker (expressive writing research); narrative psychology (writing organizes experience)
Blind spots: Very brief protocol may be insufficient for complex presentations; limited therapist contact compared to PE
Therapeutic voice: Write about the worst moment of the trauma for 30 minutes. Include every detail you remember.
Choosing between them
CPT (Cognitive-Behavioral) and Written Exposure Therapy (Trauma-Focused) 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.
