About this study

Official title: Treating OUD/PTSD in Residential Care: Written Exposure in Substance Treatment (WEST).

The purpose of this pilot non-randomized, uncontrolled clinical trial is to test the feasibility and efficacy of written exposure therapy (WET) for posttraumatic stress disorder (PTSD) as adapted for use within the context of residential substance use disorder (SUD) treatment. All participants meet criteria for PTSD and are in a short term residential SUD treatment program (target residential treatment duration = 28 days) regardless of the research. The main question the study aims to answer is: 1) Is the delivery of adapted WET feasible and acceptable in short term residential SUD treatment for individuals with severe SUD?

What participants receive

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

  • Written Exposure TherapyBehavioural

    Written Exposure Therapy is a brief, evidenced based intervention for PTSD. WET is generally delivered individually across 5 sessions in which the therapist guides the patient through writing exercises. Across exposure sessions, participants experience habituation so that their symptoms decrease by the end of treatment. WET has an established evidence base in general outpatient psychotherapy for PTSD, but has not been adapted or tested in residential SUD treatment settings. Further, the investigators have adapted WET for this setting based on stakeholder and expert feedback.

  • Treatment as UsualBehavioural

    Treatment as Usual will include a variety of standard care services offered in short term residential treatment. For example, participants receiving TAU will participate in individual case management/general counseling sessions focused on substance use disorder and its consequences, group based psychoeducation sessions, group based counseling sessions (e.g., relapse prevention planning), individual services with a medical provider and pharmacotherapy (e.g., for withdrawal, relapse prevention, or co-occurring conditions)

Study groupRoleWhat they receive
TAU + Adapted Written Exposure Therapy (WET)ExperimentalParticipants in this condition receive everything included in TAU plus 5 individual sessions of WET delivered by a therapist. WET has been adapted for delivery in a residential SUD setting according to expert feedback. Sessions average less than 60 minutes and primarily involve writing about the traumatic experience that is guided by the therapist.
Receives: Behavioral: Written Exposure Therapy; Behavioral: Treatment as Usual

What is being measured

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

  1. PTSD symptom reduction

    PTSD symptom reduction pre/post intervention by treatment arm as measured by the posttraumatic checklist for DSM-5 (PCL-5). The PCL-5 is a self-report questionnaire yielding scores ranging from 0-80 with higher scores indicating greater symptomology.

    Measured: Pre-WEST intervention; post-WEST intervention (approximately 14 days after randomization, but will vary based on when participants complete the intervention); 4-weeks post enrollment; 8-weeks post enrollment; 12-weeks post enrollment.

Secondary outcomes (2)
  1. Feasibility of WET delivered in residential SUD treatment context

    Percentage of participants in the WET arm who were able to complete the treatment (5 sessions) prior to discharge

    Measured: Up to 4 weeks, or until the participant discharges from residential treatment (whichever comes first).

  2. Acceptability of WET delivered in residential SUD treatment context

    Treatment satisfaction scores among WET participants as measured by the 2-part credibility/expectancies questionnaire (CEQ). The CEQ utilizes two scoring systems that range from 1-9 or 0%-100%. with higher scores indicating greater acceptability.

    Measured: Collected post intervention window (approximately 3 weeks from enrollment)

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 3 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: finished, as of the sponsor's last update on 29 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

PTSD symptom reduction (time frame: Pre-WEST intervention; post-WEST intervention (approximately 14 days after randomization, but will vary based on when participants complete the intervention); 4-weeks post enrollment; 8-weeks post enrollment; 12-weeks post enrollment.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07108608, which also lists 1 linked publication.

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 29 Jun 2026.
