Read the detailed description

This study is investigating a new brief psychotherapy for post-traumatic stress disorder (PTSD) which, modifies an already proven psychotherapy for PTSD by adding two new components and modifying several others. The goal of the study is to determine whether this experimental treatment outperforms the well-established standard treatment. Individuals between the ages of 18-65 with chronic PTSD are randomly assigned to one of three psychotherapy conditions: (a) brief enhanced exposure therapy; (b) standard prolonged exposure therapy; and (c) delayed standard exposure therapy. All study participants undergo a phone and face-to-face screening assessment to determine study eligibility and baseline (pretreatment-Week 0) symptom severity. Upon completing treatment, participants undergo three additional assessment visits (Week 6, Week 10, and Week 22). During each of these outcome assessment visits, participants complete a structured clinical interview and a battery of computer-administered questionnaires.

    Brief Enhanaced Exposure Therapy

    The following interventions are included in this arm: 1. Psycho-education addressing common reactions to trauma 2. Revisiting the Trauma memories 3. Processing the trauma memories 4. In vivo Exposure homework 5. \*Use of a brief pre-exposure trauma memory retrieval trial 6. Exposure to video clips related to the patient's trauma 7. Compound extinction - simultaneously exposing patient to trauma video clips while they listen to their trauma script

    Behavioral: Revisiting the Trauma memories · Behavioral: Processing the trauma memories · Behavioral: Psychoeducation · Behavioral: Trauma Memory Retrieval Trial · Behavioral: Exposure to video clips related to the patient's trauma · Behavioral: Exposure Homework · Behavioral: Compound extinction

  • Active comparator
    Standard Prolonged Exposure Therapy

    The following interventions are included in this arm: 1. Psycho-education addressing common reactions to trauma 2. Revisiting of the Trauma memories 3. Processing the trauma memories 4. Breathing retraining 5. In vivo Exposure homework

    Behavioral: Revisiting the Trauma memories · Behavioral: Processing the trauma memories · Behavioral: Psychoeducation · Behavioral: Breathing retraining · Behavioral: Exposure Homework

  • No intervention
    Delayed Treatment Control

    Patients assigned to this arm receive assessment only (Week 0, 3, and 6) prior to receiving standard prolonged exposure therapy using the Foa et al treatment manual.

Interventions

  • BehavioralRevisiting the Trauma memories

    Patient engages in repeated revisiting of their trauma memory under the guidance of the therapist for about 40 minutes. During each revisiting trial the patient closes their eyes and verbally describes the trauma and the feeling and thoughts experienced during the trauma.

    Also known as: Trauma Revisiting

  • BehavioralProcessing the trauma memories

    The patient and therapist discuss the patient's experience during the trauma revisiting with the goal of helping the patient gain alternative perspectives of the trauma.

    Also known as: Trauma Processing

  • BehavioralPsychoeducation

    Through patient handouts and didactic instruction, the patient learns about the common reactions to trauma and the rationale for exposure therapy.

  • BehavioralTrauma Memory Retrieval Trial

    Prior to the start of Imaginal Exposure, the patient is asked to recall a threatening element of their trauma memory for 1 minute. This is followed by a 30-minute rest-period prior to beginning imaginal exposure.

    Also known as: Fear Retrieval

  • BehavioralExposure to video clips related to the patient's trauma

    Patient is seated in front of a computer monitor and instructed to view a 30-min looped video clip that thematically resembles the patient's trauma.

    Also known as: Exposure to trauma clips

  • BehavioralBreathing retraining

    Patient is seated comfortably in a chair and instructed to breathe slowly and deeply in a relaxed manner.

    Also known as: Relaxed breathing

  • BehavioralExposure Homework

    Therapist assists the patient in identifying trauma-related situations/activities that the patient is avoiding and encourages the patient to begin to confront these situations between sessions.

    Also known as: In vivo exposure outside of session

  • BehavioralCompound extinction

    The patient repeatedly confronts the truama-related media clip while simultaneously listening to their own trauma script through headphones.

    Also known as: Deepened Extinction
