Understanding Prolonged Exposure Therapy: Principles & Case Study for PTSD

Prolonged Exposure (PE) is a structured, evidence-based treatment for post-traumatic stress disorder (PTSD) that helps individuals process traumatic memories and reduce avoidance through gradual, supported exposure.

What is Prolonged Exposure (PE)?

PE is a manualised cognitive-behavioural treatment developed for PTSD. It focuses on helping clients confront trauma-related memories (imaginal exposure) and avoided safe-but-feared situations (in vivo exposure) in a repeated, controlled way to reduce fear, avoidance and distress over time.

Core Principles of PE

Habituation: Repeated exposure reduces the intensity of fear responses.
Emotional Processing: Processing traumatic memories allows integration of corrective information.
Graduated Approach: Start with less distressing items and progress with mastery.
Safe, Supported Exposure: Therapist guides and monitors anxiety, teaches grounding and coping skills.
Homework & Repetition: Rehearsal between sessions is essential (imaginal scripts, in vivo assignments).

Typical PE Session Structure

Assessment & psychoeducation about trauma and avoidance.
Breathing retraining / grounding as stabilization skills.
Imaginal exposure: client recounts trauma narrative in detail (audio-recorded) and revisits it each session.
Processing: therapist helps integrate stuck points and update meanings.
In vivo exposure: assigned real-world tasks to confront avoided situations safely.
Homework review and planning for next exposure.

Contraindications & Cautions

PE is effective but must be used appropriately. Consider delays or adapted approaches when the client has:

Unstable medical conditions, active suicidal intent, or active severe substance dependence (stabilise first).
Severe dissociation — use grounding/stabilization or phased approaches before full PE.
Recent, ongoing threat or active danger — ensure safety before exposure work.

Evidence & Outcomes

PE has strong empirical support: randomized controlled trials show significant reductions in PTSD symptoms (intrusions, avoidance, hyperarousal) and improved functioning. Many clients show durable gains at follow-up when homework adherence is good.

Case Study — Illustrative Example (Adapted & Anonymised)

Background

Client: “A”, 32-year-old female; single-episode trauma — physical assault 10 months prior. Key problems: intrusive memories, nightmares, avoidance of walking alone, hypervigilance, sleep disturbance, social withdrawal.

Assessment & Formulation

PTSD symptoms meeting diagnostic criteria; avoidance maintained fear and limited processing.
Beliefs: “The world is dangerous” & “I can’t trust myself.” These maintained hypervigilance and avoidance.

Therapy Plan (12 weekly sessions)

Sessions 1–2: Psychoeducation, breathing retraining, safety planning, hierarchy for in vivo tasks.
Sessions 3–10: Imaginal exposure (20–30 minutes per session) — client recounts the assault while therapist records.
Between sessions: Daily listening to recorded narrative (homework) and graded in vivo tasks (short walks in safe, gradually less populated routes, then solo errands).
Sessions 11–12: Consolidation, relapse prevention, review of progress and coping strategies.

Progress & Outcome

Initial sessions: SUDS (Subjective Units of Distress) during imaginal exposure peaked high (8–9/10) but gradually decreased within and across sessions.
By Week 8: Significant reduction in avoidance; client could walk alone for short errands and sleep improved.
At treatment end: Clinically meaningful reduction in PTSD symptom score; fewer nightmares and intrusive memories; improved social engagement.
Follow-up at 3 months: Gains maintained; client continued in vivo practice and used recording as booster if distress returned.

          Clinical Note: The therapist used careful pacing, frequent grounding checks, and adjusted homework intensity when the client reported spikes in anxiety. This balancing of challenge and safety is critical.
        

Practical Tips for Therapists

Thoroughly assess risk, dissociation and stability before starting PE.
Provide clear rationale and collaborative consent — clients who understand the “why” engage better.
Start with stabilization skills (breathing, grounding) and build a graded exposure hierarchy together.
Use audio recordings for imaginal homework and review homework adherence each session.
Monitor SUDS and adjust pace — decline in distress is expected across sessions, not necessarily within the first few.
Coordinate with other providers (psychiatry, GP) when medication or medical needs exist.

Frequently Asked Questions (FAQs)

Will PE make the person feel worse before they get better?

Short-term increases in distress can occur because clients confront avoided memories. With proper pacing, skills and therapist support, distress reduces across sessions and long-term outcomes are positive.

How long is a typical course of PE?

Standard PE protocols run 8–15 sessions depending on complexity. Homework adherence and comorbidities influence duration.

Is PE suitable for children?

Modified exposure-based approaches are used with children (with caregiver involvement and play/age-appropriate techniques). Specialist child trauma therapies may be preferable.

What if a client dissociates during exposure?

Pause exposure, use grounding/stabilization, and consider slower pacing or preparatory work (phase-based treatment) before resuming full imaginal exposure.

Understanding Prolonged Exposure Therapy: Principles and Case Study for PTSD

Prolonged Exposure (PE) Therapy is an evidence-based treatment for Post-Traumatic Stress Disorder (PTSD). It helps individuals gradually face trauma-related memories, emotions, and situations that they have been avoiding. Through structured exposure, emotional healing occurs and fear responses begin to reduce.

What Is Prolonged Exposure Therapy?

PE is a cognitive-behavioral treatment developed by Dr. Edna Foa. It focuses on reducing PTSD symptoms by helping individuals confront trauma memories in a safe, therapeutic environment.

Core Principles of Prolonged Exposure

Emotional Processing: Facing and understanding trauma reduces fear.
Habituation: Repeated exposure decreases emotional intensity.
Correcting Misconceptions: Helps challenge beliefs such as “I am not safe” or “It was my fault.”
Building Confidence: Clients learn they can tolerate distress and reclaim life.

Key Components of Prolonged Exposure Therapy
Psychoeducation: Understanding trauma and avoidance patterns.
Breathing Retraining: Learning to calm the body.
In-Vivo Exposure: Facing real-life avoided situations safely.
Imaginal Exposure: Revisiting and narrating the trauma memory repeatedly.
Processing the Experience: Discussing insights and emotions after exposure.

How PE Helps People with PTSD

Reduces fear and avoidance.
Improves daily functioning.
Decreases flashbacks and nightmares.
Builds emotional resilience.
Restores a sense of safety and control.

Case Study: Prolonged Exposure Therapy in Action

Client: “R” – 32-year-old Female, Survivor of a Road Accident

Background: R experienced a severe road accident that caused intense fear, nightmares, and avoidance of travel. She refused to get into a car for months and experienced frequent flashbacks.

1. Assessment & Psychoeducation

The therapist explained PTSD symptoms and how avoidance maintained her fear. R learned the purpose of exposure therapy.

2. In-Vivo Exposure

Week 1: Standing near a parked car.
Week 2: Sitting inside the car without movement.
Week 3: Short rides around her neighborhood.
Week 4: Gradually increasing distance and speed.

Her anxiety reduced significantly after repeated exposures.

3. Imaginal Exposure

R narrated the accident details in a safe therapeutic space. She repeated the narration multiple times each session.

Initially, she cried and felt overwhelmed, but gradually she felt more in control.

4. Processing the Memory

The therapist helped her challenge beliefs such as:

“I should have prevented the accident.”
“Travel is always dangerous.”

R learned that the accident was not her fault and that occasional risks are normal in life.

Outcome

Nightmares reduced.
She resumed normal travel.
Fear decreased from 9/10 to 2/10.
Improved confidence and daily functioning.
