Prolonged Exposure Therapy
Prolonged Exposure Therapy is a cognitive-behavioral psychotherapy developed by Edna Foa in 1986. Its core mechanism: repeated imaginal and in-vivo exposure to trauma-related stimuli activates fear structure and provides corrective information. This catalogue links it to PTSD, typically in individual format, short (8-15).

How Prolonged Exposure Therapy works
Repeated imaginal and in-vivo exposure to trauma-related stimuli activates fear structure and provides corrective information
Ontology
Fear structure with pathological associations; avoidance prevents emotional processing
Therapeutic Voice
"I want you to close your eyes and tell me what happened, in the present tense, as if it's happening right now."
View of the Person
A being whose pathological fear structure contains correctable associations activated through confrontation

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 Prolonged Exposure (PE). 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 PE for adult PTSD. The American Psychological Association’s 2025 guideline also strongly recommends PE 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 PE is superior to every active psychotherapy or validate the catalogue’s legacy response rates.

Read the recommendation and its scope. A source may discuss an approach without recommending it.
- Clinical Practice Guideline for Management of PTSD and Acute Stress Disorder
Recommendation for the stated population
PE is one of three specifically named strongly recommended trauma-focused psychotherapies.
Scope: Adults with PTSD
- Post-traumatic stress disorder (NG116)
Recommendation for the stated population
NICE explicitly includes PE among trauma-focused CBT interventions.
Scope: Adults with clinically important PTSD symptoms; timing and diagnosis determine the recommendation
- Clinical Practice Guideline for the Treatment of Posttraumatic Stress Disorder in Adults
Recommendation for the stated population
APA strongly recommends PE 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
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.
- Clinical Practice Guideline for the Treatment of Posttraumatic Stress Disorder in Adults
Insufficient evidence for or against
APA finds insufficient evidence to prefer PE over those comparators. Its recommendation versus no treatment or usual care does not establish superiority over active therapy.
Scope: Adults with PTSD; PE versus the other active psychological treatments listed in the table.
- Clinical Practice Guideline for the Treatment of Posttraumatic Stress Disorder in Adults
Recommendation for the stated population
APA strongly recommends this combination; the table includes PE plus usual care and the COPE protocol.
Scope: Adults with PTSD and co-occurring SUD; PE-based treatment plus usual SUD care versus usual SUD care alone.
- mhGAP evidence profile STR1/STR2: PTSD psychological interventions
Discussed in the source
The WHO evidence review includes PE within individual trauma-focused CBT. The clinical recommendation is for that class, not a separately graded PE recommendation.
Scope: Adults with PTSD
Recorded material under review
The existing notes below are retained separately from assessment records. These recorded claims await source checking, including study design, recommendations and numerical estimates.
Powers et al. (2010).
VA/DoD's 2023 PTSD guideline gives a strong recommendation for individual, manualized PE for adults with PTSD, alongside CPT and EMDR (recommendation 8). The American Psychological Association's 2025 guideline also strongly recommends PE compared with no intervention or treatment as usual. These recommendations do not establish superiority over every other active treatment.

Clinical cautions and blind spots
Assessment and precautions
Recorded cautions include active suicidality with imminent risk, active psychosis, current domestic violence, severe dissociation during trauma narration, and significant self-harm behaviors. Co-occurring substance use requires coordinated assessment and care, including immediate intoxication or withdrawal needs; the diagnosis alone does not rule out trauma-focused treatment or establish a need for a separate stabilization phase first.
Sources for the corrected statements:
Blind spots
Assess practical safety, support and barriers to engagement, and adapt care accordingly. NICE NG116 recommendation 1.7.2 says drug or alcohol misuse alone should not exclude someone with PTSD from treatment. Recommendation 1.7.1 usually prioritizes PTSD treatment when depression co-occurs, but prioritizes depression when its severity prevents PTSD therapy or there is a risk of harm to self or others. Recommendation 1.7.3 calls for support with engagement barriers and attention to safety and stability. The protocol's attention to relational and meaning dimensions remains a clinical consideration, not a finding assessed here.
