Cognitive Processing Therapy (CPT)
A comprehensive guide to Cognitive Processing Therapy: how CPT treats PTSD by addressing stuck points and trauma-related beliefs, and how it compares to EMDR and Prolonged Exposure.
What Is Cognitive Processing Therapy?
Cognitive Processing Therapy (CPT) is a structured, evidence-based psychotherapy developed in 1988 by psychologist Patricia Resick to treat Post-Traumatic Stress Disorder (PTSD). It is one of the most extensively researched trauma treatments and is strongly recommended by the American Psychological Association, the VA/DoD Clinical Practice Guidelines, and the International Society for Traumatic Stress Studies.
CPT is based on the idea that after a traumatic event, people develop beliefs — called stuck points — about why the trauma happened and what it means about themselves, others, and the world. These stuck points maintain PTSD symptoms by keeping you trapped in cycles of guilt, shame, distrust, and hypervigilance. CPT helps you identify and challenge these beliefs so you can process the trauma and move forward.
CPT was originally developed for sexual assault survivors but has since been validated across diverse trauma populations, including combat veterans, survivors of childhood abuse, motor vehicle accident survivors, and refugees.
How It Works
CPT follows a structured 12-session protocol, with each session lasting about 50 minutes. The therapy moves through a clear sequence.
Sessions 1-2: Education and Engagement
You learn about PTSD, the cognitive model of trauma, and how CPT works. You begin to identify your stuck points — the beliefs that are keeping you trapped. Common stuck points include "It was my fault," "I can never trust anyone," and "The world is completely dangerous."
Sessions 3-4: Processing the Trauma
In the original CPT protocol, you write a detailed impact statement describing the meaning of the traumatic event — why you believe it happened and how it has changed your views of yourself, others, and the world. You then read this statement aloud in session. A variant called CPT-Cognitive Only (CPT-C) omits the written trauma account and focuses exclusively on cognitive work; research suggests CPT-C is equally effective.
Sessions 5-12: Challenging Stuck Points
The bulk of CPT involves systematically examining and modifying stuck points using Socratic questioning and structured worksheets. You learn to use tools like the ABC Worksheet (identifying activating events, beliefs, and consequences) and Challenging Questions Worksheet to evaluate the evidence for and against your stuck points.
The final sessions address five key themes that trauma commonly disrupts: safety, trust, power/control, esteem, and intimacy. You examine how the trauma affected your beliefs in each of these areas and develop more balanced alternatives.

What to Expect
CPT sessions are structured and focused. You will have practice assignments between sessions — typically worksheets that help you identify and challenge stuck points. The therapy requires active engagement and willingness to examine painful beliefs.
Sessions 1-4 can feel emotionally intense as you begin confronting the meaning of the trauma. Sessions 5-12 gradually shift toward empowerment as you develop more balanced thinking. Most people notice meaningful improvement by mid-treatment.
CPT can be delivered individually or in group format. Group CPT follows the same 12-session structure and has been shown to be effective in both civilian and military settings. The therapy has also been successfully delivered via telehealth.
Conditions It Treats
CPT was developed specifically for PTSD and has its strongest evidence there. It is effective for PTSD resulting from:
- Sexual assault and abuse
- Combat and military trauma
- Childhood trauma and abuse
- Domestic violence
- Motor vehicle accidents
- Natural disasters
- Refugee experiences
CPT also reduces co-occurring depression, guilt, shame, and anxiety that commonly accompany PTSD. For more complex presentations, see our guide to Complex PTSD Treatment.
Effectiveness
CPT has been tested in over 30 randomized controlled trials. It consistently produces large effect sizes for PTSD symptom reduction, with approximately 53% of patients losing their PTSD diagnosis by the end of treatment. The VA and DoD consider CPT one of the top-tier treatments for PTSD.
Compared to EMDR, CPT places more emphasis on directly challenging trauma-related beliefs through structured cognitive work, while EMDR uses bilateral stimulation and focuses more on memory reprocessing. Both are highly effective, and the choice often comes down to personal preference. Compared to Prolonged Exposure, CPT involves less in-session reliving of the trauma and more cognitive restructuring — making it a preferred option for some people who find prolonged imaginal exposure too distressing.
The original CPT protocol includes writing a trauma account, but a version called CPT-C (Cognitive Only) skips this component and focuses exclusively on challenging stuck points through worksheets and discussion. Research shows CPT-C is equally effective, so you and your therapist can choose the approach that feels right for you.
A stuck point is a belief about the trauma, yourself, others, or the world that keeps you trapped in PTSD. Examples include 'I should have prevented it,' 'No one can be trusted,' or 'I am permanently damaged.' CPT helps you identify these beliefs and examine whether they are accurate and helpful.
CPT is a structured, manualized protocol with a specific sequence of sessions and targeted worksheets. Unlike open-ended talk therapy, CPT follows a clear path and teaches specific cognitive skills. It is designed to be completed in approximately 12 sessions.
Yes. Group CPT has been extensively studied and is effective for PTSD. The group format follows the same 12-session structure and can provide additional benefits from shared support and the realization that others have similar stuck points.
Both CPT and EMDR are top-tier evidence-based treatments for PTSD. CPT focuses on identifying and changing trauma-related beliefs through structured cognitive work. EMDR focuses on reprocessing traumatic memories using bilateral stimulation. Both produce similar outcomes, and the best choice often depends on personal preference.
