    Recommendation for the stated population

    APA strongly recommends CPT as a first-line adult PTSD treatment compared with no intervention or treatment as usual.

    Scope: Adults with PTSD; comparison with no intervention or treatment as usual

  • Clinical Practice Guideline for Management of PTSD and Acute Stress Disorder

    VA/DoD · 2023 · Clinical guideline · Recommendation 34; Table 6, p.38; discussion pp.82–83

    Discussed in the source

    VA/DoD suggests co-occurring disorders should not preclude these PTSD treatments. This addresses access to treatment, not a separate claim of treating substance use.

    Scope: PTSD with co-occurring substance-use disorder or other disorders; therapies named in recommendations 8 and 9.

    VA/DoD · June 2021; version 3.0 · Clinical guideline · Recommendation 12; pp.23, 35–36

    Discussed in the source

    The guideline discusses CPT versus SMART-CPT while directing treatment of co-occurring behavioral disorders to their relevant guidelines. It does not make a new CPT recommendation for mTBI itself.

    Scope: Co-occurring PTSD in people with a history of mild-to-moderate traumatic brain injury.

    Discussed in the source

    The evidence profile includes CPT within individual trauma-focused CBT. STR1 recommends that category conditionally; this is not a separately graded recommendation for CPT.

    Scope: Adults with PTSD.

Condition-specific assessments

Each conclusion applies to the population and use described. These source-based assessments do not certify the full entry or replace expert clinical review.

PTSD & Acute Trauma

Population and scope: Adults with PTSD receiving individual, manualized Cognitive Processing Therapy (CPT). This assessment does not grade all acute post-trauma symptoms, prevention after exposure, childhood PTSD or every adaptation of the protocol.

Guideline recommendation

VA/DoD 2023 recommendation 8 strongly recommends individual, manualized CPT for adult PTSD. The American Psychological Association’s 2025 guideline also strongly recommends CPT compared with no intervention or usual care (printed p. 7). NICE NG116 (2018) recommendation 1.6.16 names it among individual trauma-focused CBT options after more than one month. These recommendations do not establish that CPT is superior to every active psychotherapy or validate the catalogue’s legacy response rates.

    Insufficient evidence for or against

    APA finds insufficient evidence for this efficacy comparison. Its separate comparisons with active treatments reach a different evidentiary finding.

    APA reports no difference in effect and makes no recommendation between these treatments. This is distinct from the insufficient-evidence finding versus waitlist or usual care.

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 is absorbed either by bending the event to fit prior beliefs (assimilation, most often self-blame) or by over-generalizing from it (over-accommodation, most often 'nothing is safe and no one can be trusted')

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 part of it for thirty minutes. Not a report. What you saw, what your body was doing, what you were thinking as it happened.

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.
