You have been avoiding. Avoiding the street where it happened. Avoiding conversations that might bring it up. Avoiding the news, certain smells, certain sounds anything that could pull you back there. The avoidance keeps you feeling safer in the short term. But it also keeps the trauma alive.
Prolonged Exposure therapy works by gently but systematically doing the opposite of avoidance. It is one of the most researched and most effective treatments for PTSD in the world and it is the primary treatment we use at Anxiety & OCD Treatment Specialists to treat PTSD.
This page explains exactly what Prolonged Exposure is, how it works, what treatment looks like session by session, and why it produces lasting results when other approaches have not
In-person sessions are provided in Tampa and virtual sessions are available throughout Florida and New York.
Quick Answer: What Is Prolonged Exposure Therapy?
Prolonged Exposure (PE) is a highly structured, evidence-based therapy for PTSD developed by Dr. Edna Foa at the University of Pennsylvania. It has been studied in more clinical trials than almost any other PTSD treatment. PE works by helping people gradually confront the traumatic memory and avoided situations so the brain can process the trauma fully and stop treating it as an ongoing emergency. PE typically takes 8 to 15 sessions and produces strong, lasting results.
Why Avoidance Keeps PTSD Going
After a traumatic event, avoidance makes sense. Avoiding people, places, memories, and situations connected to the trauma reduces distress in the short term. The problem is that avoidance prevents the brain from processing what happened.
Every time you avoid a trauma reminder, your brain reinforces the message: “This is too dangerous to face. Stay away.” The feared memory stays raw and unprocessed ready to fire a full alarm response at the slightest trigger. The PTSD stays active because the avoidance prevents the natural healing process.
PTSD is not caused by being weak. It is caused by a brain that got stuck protecting you from a threat that is no longer present. Prolonged Exposure gives the brain the experience it needs confronting the memory in safety to finally update that threat response.
The Two Core Components of Prolonged Exposure
1. Imaginal Exposure
Imaginal exposure involves revisiting the traumatic memory in a structured, guided way during therapy sessions. You close your eyes and describe the traumatic event in the present tense as if it is happening now while your therapist supports you through the process.
This is done repeatedly, over multiple sessions, until the memory no longer triggers the same flood of panic and distress. Each time you revisit the memory and survive it without the feared outcome happening, your brain updates: this is a memory, not a current emergency.
Trauma scripts are created in present tense and read repeatedly until the brain elicits no fear or panic response. Most clients are surprised at how quickly this works.
2. In Vivo Exposure
In vivo means "in real life." In vivo exposure involves gradually returning to the safe situations, places, and activities you have been avoiding since the trauma. You and your therapist build a list of avoided situations ranked from least to most distressing and work through them systematically.
For example, someone who was in a car accident may avoid driving. In vivo exposure might start with sitting in a parked car, then driving around a quiet parking lot, then driving on familiar roads, and gradually extending to highways and the specific route where the accident occurred.
Each in vivo step is practiced repeatedly until the distress naturally decreases teaching the brain that these situations are safe, not dangerous.
What Prolonged Exposure Is NOT
PE is not ‘flooding’ being thrown into the most terrifying memory or situation all at once. It is not done without preparation. You spend the first sessions building skills and understanding before any exposure work begins.
PE is not meant to re-traumatize. The distress that arises during exposure is manageable, temporary, and always decreases with time and repetition. Your therapist is with you throughout the process, regulating the pace and checking in consistently.
PE is collaborative. Nothing happens before you understand why it is being done and feel adequately prepared. The pace is yours.
What PE Treatment Looks Like Session by Session
Here is how a typical course of Prolonged Exposure therapy unfolds:
| Phase | What Happens |
|---|---|
| Sessions 1–2: Education & Rationale | You learn about PTSD how it develops, why avoidance keeps it going, and how PE interrupts that cycle. You and your therapist discuss the trauma history, current symptoms, and treatment goals. A brief hierarchy is created and the first exposures are done during the second session. |
| Sessions 2–3: In Vivo Hierarchy | You continue to build your in vivo exposure hierarchy — a ranked list of safe situations you have been avoiding, from least to most distressing. You are given new, and possibly more exposure, to complete during session and then complete as homework between sessions. |
| Sessions 3–4: First Imaginal Exposure | The first imaginal exposure session. You revisit the traumatic memory in detail, in the present tense, with your therapist. You process what came up emotionally and cognitively afterward. If time permits, the first draft of a trauma script is created. |
| Sessions 5–10: Repetition & Processing | You continue imaginal exposure across multiple sessions returning to the memory and expanding on the trauma script, and practicing in vivo exposure steps. Distress levels are tracked. Processing discussions after each imaginal exposure help shift stuck beliefs. |
| Sessions 11–15: Generalization & Closure | As distress decreases significantly, harder in vivo steps are tackled. Final sessions focus on consolidating gains, planning for potential setbacks, and celebrating meaningful recovery. Most people complete PE in 8 to 15 sessions total. |
What Makes PE Different From General Therapy
Many people with PTSD have been in therapy before without seeing significant improvement. This is often because general talk therapy discussing feelings, exploring the past, processing emotions is not the same as evidence-based trauma treatment.
PE is different in several important ways:
- It is structured and time-limited. PE follows a clear protocol. You know what to expect at each session and can track your progress.
- It directly targets avoidance. Most general therapy does not systematically address the avoided memories and situations that keep PTSD active.
- It uses repetition intentionally. The between-session practice listening to recordings or reading scripts, completing in vivo steps is where much of the healing happens. PE is not just a once-a-week conversation.
- It has the research behind it. PE has been studied in more clinical trials than almost any other PTSD treatment. It works across trauma types — combat, sexual assault, accidents, childhood trauma, and more.
People often say: ‘I have talked about this for years and it never helped.’ Talking about trauma and processing trauma are different things. PE provides the specific conditions the brain needs to fully process a traumatic memory not just discuss it.
How Does PE Compare to Other PTSD Treatments?
| Prolonged Exposure (PE) | Other PTSD Approaches |
|---|---|
| Directly confronts the traumatic memory | CPT: focuses on trauma-related beliefs, less direct memory revisiting |
| Uses both imaginal and in vivo exposure | EMDR: bilateral stimulation while briefly holding memory fewer sessions for single-incident trauma |
| Between-session practice is a core component | Talk therapy: explores trauma but without systematic exposure often insufficient alone |
| 8 to 15 structured sessions | Medication: can reduce symptom intensity but does not process the trauma |
| Strongest research base for most trauma types | All evidence-based therapies can be effective the right choice depends on the person |

Who Is PE Right For?
PE is appropriate for a wide range of trauma types and presentations. It has strong evidence for:
- Combat and military trauma
- Sexual assault and rape
- Physical assault
- Accidents and disasters
- Childhood trauma in adults
- Medical trauma
- Witnessing death or violence
- First responder and emergency services trauma
PE is generally recommended for adults and older teens. For younger children, Trauma-Focused CBT (TF-CBT) is typically the treatment of choice though the underlying principles of exposure are similar.

PE works effectively via telehealth. Imaginal exposure sessions are conducted over video with your therapist present in real time. Between-session practice listening to or reading trauma scripts and completing in vivo steps happens in your own environment, which is often where the most meaningful progress occurs.
Frequently Asked Questions
Will I have to talk about my trauma in detail?
Yes imaginal exposure involves describing the traumatic memory in detail, however, the trauma can be discussed in steps and over multiple sessions. This is the part of PE that most people feel anxious about before starting. It is important to know that the first session of imaginal exposure is almost always more manageable than people expect. You are not alone during it your therapist is present and guiding the process throughout. And the distress decreases significantly with each repetition.
What if I start crying or feeling overwhelmed during a session?
Emotional responses during imaginal exposure are completely normal and expected. They are actually a sign that the therapy is working you are making real contact with the traumatic memory rather than pushing it away. Your therapist is trained to support you through these moments. Sessions are never rushed. You will not be left alone in distress.
How quickly will I start feeling better?
Most people notice meaningful improvement within the first three to four sessions of imaginal exposure. The distress during exposure practice decreases measurably across sessions and this reduction in distress is tracked at every appointment. By the end of a full PE course, the majority of people no longer meet criteria for PTSD. Some experience lasting remission after just 8 to 10 sessions.
What if my PTSD came from something that happened a long time ago?
PE is equally effective for PTSD that developed years or decades ago. The brain processes traumatic memories the same way regardless of when they occurred. Many people carry unprocessed trauma for most of their lives and see full remission after a course of PE. The length of time since the trauma does not predict treatment outcome engagement and practice do.
