Face your fears safely and reclaim your life from trauma
After trauma, it’s natural to want to avoid reminders of what happened. You might push away memories, avoid places or people associated with the experience, and try not to think or talk about it. While understandable, this avoidance comes at a cost—it keeps the trauma alive, limits your life, and prevents natural healing.
Prolonged Exposure (PE) therapy provides a safe, structured way to face what you’ve been avoiding. By gradually confronting trauma memories and real-life situations, you can process what happened and reduce the power it holds over you. At Clarity Psychology, our Melbourne psychologists are trained in Prolonged Exposure and have helped many people recover from PTSD.
What is Prolonged Exposure?
Prolonged Exposure is a specific treatment for Post-Traumatic Stress Disorder (PTSD) developed by Dr Edna Foa at the University of Pennsylvania. It’s based on emotional processing theory, which explains how trauma memories become “stuck” and how they can be processed through controlled exposure.
When we experience trauma, the memory can become fragmented, highly emotional, and not properly integrated into our life story. We may develop beliefs that the world is extremely dangerous, that we’re incompetent, and that the memory itself is dangerous. To cope, we avoid: we avoid reminders, avoid thinking about it, avoid talking about it.
This avoidance prevents natural processing. The memory stays raw, easily triggered, and emotionally charged. The avoided situations continue to seem dangerous. The beliefs about danger and incompetence go unchallenged.
Prolonged Exposure breaks this cycle through two types of exposure: imaginal exposure (revisiting the trauma memory) and in vivo exposure (facing avoided real-life situations).
How Does Prolonged Exposure Work?
PE follows a clear structure over 8-15 sessions:
Session 1: Overview and Rationale
Your therapist explains how PTSD develops, why avoidance maintains it, and how exposure helps. Understanding the rationale helps you engage with what can feel counterintuitive.
Session 2: Breathing Retraining and In Vivo Hierarchy
You’ll learn breathing techniques for managing distress. You’ll also create a hierarchy of avoided situations (places, activities, people) ranked by how much distress they cause. These become targets for in vivo exposure.
Sessions 3-12+: Imaginal and In Vivo Exposure
Each session typically includes:
Review: Discussing in vivo exposure homework from the previous week.
Imaginal Exposure: With eyes closed, you describe the trauma memory in detail, in present tense, as if it’s happening now. This typically lasts 30-45 minutes. Your therapist records this so you can listen to it between sessions.
Processing: After imaginal exposure, you discuss what came up—thoughts, feelings, insights.
Planning: Setting up in vivo exposure homework for the coming week.
Final Sessions: Review and Relapse Prevention
Treatment concludes with reviewing your progress, consolidating skills, and planning for the future.
The Two Types of Exposure
Imaginal Exposure
Imaginal exposure involves revisiting the trauma memory in your imagination. You describe the experience aloud in detail, including what happened, what you thought and felt, and sensory details. Initially, this is distressing—that’s expected and part of the process.
With repeated exposure, the memory becomes less overwhelming. Your brain processes what it couldn’t at the time. The memory transforms from a raw, present-tense nightmare into a past event that can be recalled without being flooded.
In Vivo Exposure
In vivo exposure involves gradually confronting situations you’ve been avoiding in real life. If you’ve been avoiding driving since a car accident, you might start by sitting in a parked car, then driving around the block, then driving further, then driving past the accident site.
The hierarchy you create ensures exposure is gradual—challenging enough to create progress, but not so overwhelming that you can’t manage it.
What Happens During Exposure?
When you face avoided trauma memories or situations, anxiety naturally rises. This is expected. But if you stay with the experience rather than escaping, something important happens: anxiety naturally decreases. This is called habituation.
With repeated exposure, several things occur. Within-session habituation: Anxiety decreases during each exposure session. Between-session habituation: Peak anxiety becomes lower with each session. Disconfirmation: You learn the feared outcomes don’t occur (e.g., you don’t “go crazy,” the memory doesn’t destroy you). Changed meaning: The way you understand the trauma shifts.
What to Expect in Prolonged Exposure
Initial Distress
The first few sessions involving imaginal exposure are often the hardest. Anxiety may temporarily increase as you confront what you’ve been avoiding. This is a normal part of the process, not a sign that therapy isn’t working.
Homework
PE requires significant between-session work. You’ll listen to the recording of your imaginal exposure daily and complete in vivo exposure assignments. This practice is essential—exposure works through repetition.
Session Length and Frequency
Sessions are typically 90 minutes to allow adequate time for exposure and processing. Weekly sessions are standard to maintain momentum.
Duration
Most people complete PE in 8-15 sessions. The exact number depends on the complexity of your trauma and how quickly you progress.
What You Might Notice
As treatment progresses, people often notice: trauma memories becoming less vivid and emotionally charged, fewer nightmares and intrusive memories, increased ability to engage in previously avoided activities, a shift in beliefs about themselves and the world, and improvement in overall mood and functioning.
The Evidence for Prolonged Exposure
Prolonged Exposure is one of the most researched and effective treatments for PTSD. Key findings include: large effect sizes in numerous randomised controlled trials across diverse trauma types, recognition as a first-line PTSD treatment by the American Psychological Association, VA/DoD clinical practice guidelines, and International Society for Traumatic Stress Studies, effectiveness for military combat trauma, sexual assault, childhood abuse, accidents, and other trauma types, and benefits maintained at long-term follow-up.
The evidence for PE is strong enough that it’s considered a gold-standard trauma treatment worldwide.
Common Questions About PE
“Won’t exposure make my PTSD worse?”
Research consistently shows PE improves PTSD; it doesn’t make it worse. Some people experience temporary increased distress early in treatment, but this is part of processing and typically resolves quickly.
“What if I can’t handle it?”
Your therapist will pace treatment appropriately. You’re always in control—you can stop exposure at any time. Most people find they can tolerate more than they expected.
“I’ve tried to think about the trauma and it doesn’t help”
Briefly touching on trauma and then avoiding is different from the prolonged, repeated, structured exposure in PE. The key is staying with the experience long enough for habituation to occur.
“My trauma is too severe”
PE has been effective for severe trauma, including combat trauma and prolonged childhood abuse. Severity isn’t a contraindication.
Is Prolonged Exposure Right for You?
PE may be particularly helpful if you’re experiencing PTSD symptoms (intrusive memories, avoidance, negative mood changes, hyperarousal), if avoidance has significantly limited your life, if you want an evidence-based treatment with strong research support, and if you’re motivated to engage in challenging but effective work.
PE requires commitment to regular homework. If you’re not ready for this level of engagement, it may not be the right time.
Some conditions may require stabilisation before PE, including severe substance use, active suicidality, or significant dissociation. Your therapist will assess your suitability and may recommend preparatory work if needed.
