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
Imagery Rehearsal Therapy
Core mechanism: Cognitive rescripting of nightmare content combined with imagery rehearsal changes nightmare frequency and distress through mechanisms likely involving memory reconsolidation and reduced conditioned fear
Ontology: Nightmares as a learned maladaptive sleep behavior that can be directly targeted and modified through intentional cognitive and imaginal intervention

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.
Imagery Rehearsal Therapy
Philosophical roots: Behavioral learning theory; cognitive appraisal; Lang's emotional processing theory; sleep science
Blind spots: Requires willingness to engage with nightmare content; some find rescripting counterintuitive; not suitable during acute destabilization; limited training infrastructure
Therapeutic voice: Choose any part of the nightmare and change it any way you want. It does not have to make sense. Then we will rehearse the new version.
Choosing between them
CPT and Imagery Rehearsal Therapy both sit within the Cognitive-Behavioral tradition — they share a worldview about what suffering is and how change happens. Differences are more often about technique and emphasis than about underlying theory.
