Cognitive Processing Therapy

A 12-session protocol for PTSD that targets stuck points — the beliefs trauma left behind.

Originator: Patricia Resick (1988, for sexual assault survivors)Best for: PTSD (combat, assault, MVA, childhood) · Moral injury · Complex traumatic grief

Core idea

CPT views PTSD as a failure to integrate a traumatic event with prior beliefs. Survivors either assimilate (it must have been my fault) or over-accommodate (no one can be trusted, the world is unsafe) to preserve their schema. CPT systematically identifies these stuck points and uses Socratic dialogue and structured worksheets to develop more balanced, accommodative beliefs — particularly in safety, trust, power/control, esteem, and intimacy.

Key concepts

Stuck points
Concise belief statements (under ~12 words) that maintain symptoms.
Assimilation
Altering the trauma memory to fit prior beliefs (it was my fault).
Over-accommodation
Altering beliefs too extremely (I can never trust anyone).
Natural vs. manufactured emotions
Sadness about loss is natural; shame from a distorted belief is manufactured.
Five themes
Safety, trust, power/control, esteem, intimacy — assessed throughout.

What a session looks like

  1. 1
    Sessions 1–3
    Psychoeducation, impact statement (why did this happen, how has it changed me).
  2. 2
    Sessions 4–5
    Identify stuck points; introduce ABC worksheet (event → belief → consequence).
  3. 3
    Sessions 6–7
    Challenging Questions worksheet; Patterns of Problematic Thinking.
  4. 4
    Sessions 8–11
    Challenging Beliefs Worksheet through each of the five themes.
  5. 5
    Session 12
    Rewrite impact statement; compare to session 1; relapse prevention.

Signature techniques

Impact statement
Written narrative of why the trauma happened and what it means about self/others/world.
ABC worksheet
Activating event → belief → consequence; teaches the cognitive model.
Challenging Questions Worksheet (CQW)
10 questions applied to one stuck point at a time.
Challenging Beliefs Worksheet (CBW)
Integrates evidence, alternative beliefs, and re-rated emotion.
CPT vs CPT+A
Optional written trauma account (CPT+A) added between sessions 4–6; most trials show equivalence without it.

Evidence base

VA/DoD-recommended first-line treatment for PTSD. Large RCTs across military, assault, and refugee populations show response rates of 50–70% and durable gains at 5–10 year follow-up. Comparable efficacy to PE; often preferred when avoidance of exposure is a barrier.

Common pitfalls

  • Letting stuck points balloon to paragraphs — they must be short, falsifiable beliefs.
  • Drifting from protocol fidelity; CPT works best delivered as designed.
  • Confusing manufactured shame with natural sadness — leads to inappropriate targets.
  • Skipping the impact statement comparison at session 12 — it's the consolidation moment.
