A structured, manualized therapy for PTSD that focuses on identifying and challenging unhelpful beliefs about a traumatic event and its meaning.

What Is Cognitive Processing Therapy (CPT)?

Cognitive processing therapy (CPT) is a structured, manualized form of cognitive therapy specifically developed for PTSD. It focuses on identifying and challenging distorted or unhelpful beliefs, sometimes called “stuck points,” related to the traumatic event and its perceived meaning.

How It Works

CPT is based on the idea that PTSD symptoms are maintained in part by unhelpful beliefs about the trauma, oneself, others, or the world, often related to themes of safety, trust, power, esteem, and intimacy. Therapy involves examining and restructuring these beliefs using structured cognitive techniques. This is a general description using original language, not a reproduction of any specific manual content.

What Happens During Therapy?

CPT typically includes psychoeducation about PTSD, written accounts of the traumatic event and its meaning, and structured worksheets to identify and challenge stuck points, with practice assignments between sessions.

Evidence and Effectiveness

Research strongly supports CPT for PTSD, including combat-related, sexual assault-related, and other trauma types, with numerous randomized controlled trials and endorsement in major clinical practice guidelines.

Who May Benefit?

CPT may be considered as part of an individualized treatment plan specifically for people with PTSD, particularly those who engage well with structured, written cognitive exercises.

Limitations and Considerations

CPT involves engaging directly with details and meaning of the traumatic event, which can be emotionally demanding. It requires a therapist with specific training in the CPT protocol.

Finding a Qualified Therapist

CPT is delivered by psychologists, licensed clinical social workers, and other mental health professionals with specific CPT training, often available through specialized trauma treatment programs including VA and military health systems.

How Long Does Therapy Take?

CPT is typically delivered over a defined course of approximately 12 sessions, though treatment length varies according to the person and clinical presentation.

Therapy vs. Medication

For PTSD, CPT and medication are not necessarily competing options and may be used alone or in combination, in consultation with a qualified healthcare professional.

What Conditions Is It Used For?

Post-Traumatic Stress Disorder

A condition that can develop after exposure to a traumatic event, involving intrusive memories, avoidance, negative mood changes, and heightened arousal.

Related Therapy Types

Prolonged Exposure Therapy (PE)

A structured trauma-focused therapy that uses repeated, guided recounting of the traumatic memory along with real-world exposure to safe but avoided situations.

Eye Movement Desensitization and Reprocessing (EMDR)

A structured trauma therapy that uses bilateral stimulation, such as guided eye movements, while a person processes distressing traumatic memories.
