Looking for a therapist?

Prolonged exposure therapy is a treatment for individuals suffering from post-traumatic stress disorder (PTSD) and other anxiety-related disorders.

Developed in the late 1980s, this therapeutic approach is grounded in the principles of cognitive-behavioral therapy (CBT) and primarily focuses on helping patients confront and process their traumatic memories in order to reduce the distress associated with them.

Through a combination of imaginal and in vivo exposure, patients gradually learn to confront and tolerate their anxiety-provoking stimuli, leading to a reduction in PTSD symptoms and improved overall functioning.

Prolonged Exposure Therapy: An Overview

Prolonged exposure therapy

Prolonged Exposure (PE) Therapy is a well-established, evidence-based psychotherapy for individuals who have Post-traumatic Stress Disorder (PTSD) and other trauma-related disorders.

As a form of cognitive-behavioral therapy, PE helps patients confront and process their traumatic memories by gradually exposing them to triggers related to their trauma in a controlled and safe environment.

This therapeutic approach aims to reduce the distress and avoidance associated with trauma, enabling patients to lead more fulfilling lives.

In Vivo ExposureImaginal Exposure
Patients gradually face real-life situations that they have been avoiding due to their fear and anxiety. Patients recount their traumatic experiences repeatedly in a detailed and emotional manner during therapy sessions.
This process allows them to learn that their feared outcomes are less likely to occur than they initially believed.This retelling helps patients process the traumatic memories, leading to a decrease in the intensity of distress they feel when recalling the event.
Therapists work together with their patients to develop an exposure hierarchy, listing triggers from least to most distressing, and then guide patients through facing these situations in a controlled manner.It also aids in correcting inaccurate or distorted beliefs about the trauma, ultimately enhancing the sense of control and safety.

Studies have shown that Prolonged Exposure Therapy is an effective treatment for PTSD and has been proven in numerous controlled clinical trials.

PE is recognized as a gold standard treatment, and it has been widely disseminated across various clinical settings, including the Veterans Affairs (VA) Healthcare System.

While PE is predominantly utilized for PTSD treatment, it may also show promise in treating other anxiety and mood disorders, including panic disorder, social anxiety, and depression.

However, it is crucial to note that therapists must be adequately trained and equipped to adjust the therapy based on the individual’s needs and symptoms for optimal results.

Evolution of PE

Prolonged exposure therapy for PTSD

Prolonged Exposure (PE) therapy has experienced significant developments since its inception as a treatment for Post-traumatic Stress Disorder (PTSD).

PTSD is a mental health condition that arises following exposure to traumatic events, leading to various symptoms such as intrusive thoughtsavoidance behaviorsnegative changes in mood, and hyperarousal.

PE therapy focuses on addressing the intense fears and trauma-related memories associated with PTSD. This evidence-based treatment involves two primary components: imaginal exposure and in vivo exposure.

Imaginal exposure involves patients revisiting their trauma memories and recounting them in a safe environment, whereas in vivo exposure entails a gradual and controlled confrontation with situations or objects that evoke fear.

In the early stages of PE therapy, Eye Movement Desensitization and Reprocessing (EMDR) was introduced as a complementary trauma-focused psychotherapy.

EMDR has been shown to be effective in treating PTSD, but it is used alongside other methods to ensure comprehensive treatment.

Advancements in PE therapy include:

  1. Refined exposure techniques: The development of more effective strategies for approaching and confronting trauma memories through imaginal exposure.
  2. Enhanced coping skills: Incorporating cognitive restructuring, stress management, and relaxation techniques to better equip patients in managing PTSD symptoms.
  3. Integration with other therapies: Combining PE therapy with other evidence-based treatments, such as Cognitive-Behavioral Therapy, to improve overall outcomes.

The evolution of PE therapy has not only widened its scope but also led to the implementation of more flexible and individualized approaches.

For instance, patients with a history of mild traumatic brain injuries or multiple traumatic experiences can receive specialized adaptations tailored to their unique needs.

Moreover, the availability of technology has prompted further development and testing of computer- and internet-based PE therapy delivery.

This innovative approach aims to increase accessibility, reduce therapist contact time, and cut treatment costs.

In vivo Exposure

PE therapy

In vivo, exposure is a critical component of prolonged exposure therapy, specifically designed to address fears stemming from traumatic events, such as disasters, accidents, war, violence, and terror.

This technique helps individuals with post-traumatic stress disorder (PTSD) to confront their anxiety directly in a safe and controlled environment by gradually facing situations they find distressing.

Hierarchy of Fears

The process begins with creating a hierarchy of fears ranking them according to severity.

This serves as a roadmap for gradually exposing the individual to increasingly anxiety-provoking situations, ensuring that treatment is systematic and appropriately paced.

Starting with less intimidating items, the individual engages in structured exposure sessions, allowing them to gradually overcome their distress as they work their way up the hierarchy.

Homework Tasks

An essential aspect of in vivo exposure is assigning homework tasks for individuals to practice between therapy sessions.

These assignments could involve visiting locations or engaging in activities associated with their trauma.

The goal is to help them gain a sense of control over their traumatic memories and reduce avoidance behaviors that maintain PTSD symptoms.

Breaking the Cycle

In vivo exposure has shown to be an effective technique in reducing PTSD symptoms, as individuals confront their fears directly, breaking the cycle of avoidance that characterizes the disorder.

This approach can be particularly helpful for those who have experienced various forms of trauma, including disasters, accidents, war, violence, and terror.

However, it is important to note that in vivo exposure should always be conducted under the guidance of a trained professional, ensuring that the individual is adequately supported throughout the therapeutic process.

Clinical Applications

Trauma exposure therapy

Prolonged exposure therapy (PET) is a widely used approach in treating various mental health disorders such as anxiety and depression.

In this evidence-based treatment, individuals are encouraged to confront their fears and distressing memories in a safe environment to help them process their traumatic experiences and reduce symptoms of psychological distress.

Chronic Post-traumatic Stress Disorder (PTSD)

One of the key areas of clinical application for PET is in the treatment of chronic post-traumatic stress disorder (PTSD).

Among this population, veterans often benefit greatly from PET, as the treatment helps them address their anxiety, anger, and emotional avoidance behaviors.

A combination of psychoeducation, exposure to feared situations, and emotional processing allows patients to regain their sense of control and safety.

Obsessive-compulsive Disorder (OCD)

PET is also effective for treating obsessive-compulsive disorder (OCD), as it focuses on reducing compulsive behaviors and obsessions.

By systematically exposing patients to their feared stimuli and encouraging them to refrain from compulsions, PET can help break the cycle of irrational fear and avoidance characteristic of OCD.

Dissemination of PET

In order to maintain its effectiveness, the dissemination of PET is crucial.

Through publishing findings in reputable journals like the Clinical Psychology Review and Behavior Therapy, therapists and researchers can ensure that the current best practices in prolonged exposure therapy are shared among professionals.

Additionally, organizations like the Cochrane play a vital role in synthesizing research and ensuring the most up-to-date and reliable information is available to practitioners.

Using PET to address various mental health conditions is a promising approach that has shown significant success in ameliorating debilitating symptoms.

By continually refining and sharing best practices, clinicians and researchers can continue improving the lives of those struggling with anxiety, depression, PTSD, and other disorders.

PE in Other Mental Health Disorders

Prolonged exposure therapy

Prolonged Exposure (PE) therapy is predominantly utilized for treating Post-traumatic Stress Disorder (PTSD) due to its evidence-based success in reducing symptoms and improving overall mental health outcomes.

However, its applicability in addressing other mental health disorders has also gained attention among psychologists and researchers.

Anxiety DisorderAnxiety disorders such as phobias and panic disorders have demonstrated promising results when treated with PE.

For instance, virtual reality exposure is a form of PE that has been used to treat specific phobias like agoraphobia and social anxiety disorder.

It involves the use of virtual environments to gradually expose patients to the situations that cause them distress, thereby desensitizing them to their fears.
DepressionWhile not a primary treatment modality for depression, PE has shown to be effective in alleviating depressive symptoms when comorbid with PTSD.

This suggests that PE may hold promise in addressing depressive symptoms that are related to traumatic experiences.
Acute Stress DisorderSimilar to PTSD, acute stress disorder results from experiencing a traumatic event, but its symptoms typically surface within a month of the incident.

Given the similarities between PTSD and acute stress disorder, PE’s success in treating PTSD has led to its consideration as an intervention for individuals with acute stress disorder.

Pros and Cons

Pros and Cons

Prolonged exposure therapy is a widely recognized treatment for individuals who have post-traumatic stress disorder (PTSD).

However, like any therapy, it has its pros and cons. In this section, we will discuss the benefits and drawbacks of prolonged exposure therapy.


EffectivenessProlonged exposure therapy has been found to be effective in reducing PTSD symptoms and improving overall mental health.

It is based on the principle of emotional processing, which allows individuals to confront and process their traumatic experiences.
Evidence-based approachProlonged exposure therapy is supported by extensive research and is grounded in well-established psychological theories.

This evidence-based approach ensures that the treatment is rooted in proven techniques.

This adaptability indicates that it can be a valuable treatment option for a wide range of individuals.


IntensityOne of the challenges of prolonged exposure therapy is its intensity.

The treatment involves confronting and reliving traumatic experiences, which can be emotionally difficult for some individuals.

This may result in temporary increases in PTSD symptoms during the therapy process.
Potential for dropoutsDue to its demanding nature, some individuals may find prolonged exposure therapy too challenging and might not complete the treatment.

This could result in dropouts and a reduced success rate for reaching therapeutic goals.
Limited effectiveness in some casesAlthough prolonged exposure therapy is widely recognized as an effective treatment for PTSD, it may not be as beneficial for individuals with certain co-occurring mental health conditions.

These individuals might require additional or alternative treatments to achieve the desired outcomes.

It is crucial for mental health professionals to weigh the pros and cons of prolonged exposure therapy for each individual case and to work closely with their patients to determine the most effective course of treatment.

Final Thoughts

Prolonged exposure therapy

Prolonged Exposure (PE) therapy has been found to be an effective treatment for individuals suffering from Post-traumatic Stress Disorder (PTSD).

As evidenced in multiple studies, such as the one examining potential contraindications, this therapy has shown promising results in reducing PTSD symptoms.

However, it is essential to recognize that more research may be needed to fully understand the mechanisms and potential mediators of PE therapy.

In conclusion, while Prolonged Exposure therapy has proven effective for many PTSD patients, it is essential to continue research on its mechanisms, potential mediators, and factors influencing its outcomes.

This will ensure the therapy remains an efficient and reliable treatment option for those suffering from PTSD.

Frequently Asked Questions

How does prolonged exposure therapy compare to EMDR?

Prolonged exposure therapy and Eye Movement Desensitization Reprocessing (EMDR) are both evidence-based treatments for PTSD.

Prolonged exposure therapy focuses on approaching trauma-related memories and situations through imaginal and in vivo exposures.

EMDR, on the other hand, involves processing traumatic memories while doing guided eye movements.

Both treatments can be effective, but their suitability depends on individual needs and preferences.

What are the main components of prolonged exposure therapy?

Prolonged exposure therapy consists of two main components: imaginal exposure and in vivo exposure.

Imaginal exposure involves recounting the traumatic event in detail to facilitate emotional processing.

In vivo exposure involves confronting trauma-related situations or objects in a safe and controlled manner, helping patients gradually decrease their anxiety and fear.

Is prolonged exposure therapy suitable for complex PTSD?

Prolonged exposure therapy can be helpful for individuals with complex PTSD, although the treatment might need to be adapted to address the specific needs of the client.

For example, longer treatment duration or additional trauma-focused interventions might be required.

Working with a trained therapist is important to determine the most appropriate approach for each case.

What is the difference between prolonged exposure therapy and regular exposure therapy?

While both prolonged exposure therapy and regular exposure therapy involve confronting trauma-related situations, the key difference is the emphasis on emotional processing in prolonged exposure therapy.

This is achieved through the use of imaginal exposures, which allows clients to emotionally engage with the traumatic memory in a safe and controlled environment.

Regular exposure therapy may focus more on reducing anxiety through repeated exposure to feared situations without the same level of emotional processing.

When is prolonged exposure therapy not recommended?

Prolonged exposure therapy may not be recommended for individuals who have unstable psychiatric conditions or are at high risk for suicide.

It’s also important to consider the client’s ability to tolerate the emotional intensity required during sessions.

In some cases, other forms of therapy, such as cognitive processing therapy or dialectical behavior therapy, might be more appropriate.

Working with a trained mental health professional is crucial in determining the most suitable treatment option.
