About this study

Official title: Telehealth-delivered Massed Imaginal Exposure for PTSD: Toward Increasing Access to Alternative, Evidence-based Treatment Schedules for Virtual Care

The purpose of this study is to establish the safety, feasibility, and acceptability of very brief imaginal exposure therapy for post-traumatic stress disorder (PTSD) delivered by telehealth over the course of six-daily 60-minute sessions within a 10-day window. All study visits occur remotely, by telehealth. You will be asked to complete a pre-treatment assessment involving a clinical interview, video-based measures of emotional and physical reactions, such as heart rate and breathing rate, and self-report questionnaires to measure the severity and impact of trauma-related symptoms. These assessments are completed again 1-week, and 1-month after completing treatment. The researchers propose that massed exposure-based therapy delivered via telehealth will advance telemental health treatment options and personalized care for Veterans with PTSD.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • VVC-delivered Massed Imaginal ExposureBehavioural

    Consistent with Zoellner et al., (2017), six, 60-minute daily sessions of imaginal exposure will be conducted based on the PE manual (Foa et al., 2007). No in vivo exposure or homework will be included. Session 1 will include rationale for imaginal exposure and common reactions to trauma. Sessions 2-6 will focus on imaginal exposure (45 minutes) and processing (15 minutes), with later sessions focused on the most distressing aspect of the trauma memory. The final session will include relapse prevention. All sessions will be delivered within a 10-day window.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Adverse events

    Potential adverse events will be assessed with a structured as well as open-ended interview daily during treatment and at follow up.

    Measured: from admission to 1 month follow up

  2. Satisfaction with treatment - provider

    PETQ: Prolonged exposure therapist questionnaire; scores range 0-30 with higher scores suggesting patient is more engaged in treatment.

    Measured: 1 week post-treatment

  3. Satisfaction with telehealth - provider

    TTSQ-Provider: Technology Treatment Satisfaction Questionnaire; scores range 0-30 with higher scores suggesting patient is more engaged in treatment

    Measured: 1 week post-treatment

  4. Satisfaction with treatment - patient

    STTSR: Satisfaction with Therapy and Therapist Scale-Revised; scores range 0-60 with higher scores indicating higher satisfaction

    Measured: 1 week post-treatment

  5. Satisfaction with telehealth - patient

    Technology Treatment Satisfaction Questionnaire; scores range 0-60 with higher scores indicating higher satisfaction.

    Measured: 1 week post-treatment

  6. Number of sessions attended per patient

    Number of telehealth therapy appointments attended per patient.

    Measured: from pre-treatment to 1-month follow-up

  7. Rate of treatment completion and pre-mature dropout.

    Total percent of patients retained from initial patients.

    Measured: from pre-treatment to 1-month follow-up

  8. CAPS: Clinician-Administered PTSD Scale for DSM-5

    Structured interview for DSM-5 PTSD severity and impairment; Scores range from 0 to 80 with higher scores indicating greater PTSD severity and impairment.

    Measured: from pre-treatment to 1-month follow-up

  9. PTSD symptom checklist

    PCL-5: PTSD Symptom Checklist for DSM-5. Scores range from 0 to 80, with higher scores indicating greater PTSD severity and impairment.

    Measured: from pre-treatment to 1-month follow-up

Secondary outcomes (3)
  1. Remote photoplethysmography

    Video-based derivation of psychophysiology including heart rate and respiratory rate

    Measured: Pre-treatment, 1-week post-treatment, and 1-month follow-up.

  2. Facial emotional expressivity

    Video-based derivation of facial emotional expressivity.

    Measured: Pre-treatment, 1-week post-treatment, and 1-month follow-up.

  3. Vocal and linguistic emotional expressivity

Questions about this trial

What is this clinical trial studying?

A study testing VVC-delivered Massed Imaginal Exposure in people with Posttraumatic Stress Disorder, run by Medical University of South Carolina.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 8 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Adverse events (time frame: from admission to 1 month follow up). The study lists 9 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Jul 2025.
