Written Exposure in Substance Treatment (WEST 3.0): Randomized Controlled Trial (WEST)

20. august 2026 opdateret af: Rebecca Schacht, Potomac Health Foundations

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

The purpose of the current research study is to evaluate the efficacy of the refined Written Exposure in Substance Treatment (WEST) for PTSD among residential SUD patients through a randomized controlled trial. 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. Participants will be randomly assigned to WEST + treatment as usual (TAU) or TAU only. The primary outcome is change in PTSD symptoms from pre-intervention to post-intervention. The secondary outcome will be change in SUD outcomes (e.g., treatment completion, reduced opioid and other drug use) and change in non-PTSD mental health outcomes (e.g., depression) from pre-intervention to post-intervention.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Tau + Tilpasset skriftlig eksponeringsterapi (våd)
Deltagere i denne tilstand modtager alt inkluderet i Tau Plus 5 individuelle sessioner med våd leveret af en terapeut. Wet er blevet tilpasset til levering i en boligindstilling i henhold til ekspert feedback. Sessioner gennemsnit mindre end 60 minutter og involverer primært at skrive om den traumatiske oplevelse, der styres af terapeuten.
Skriftlig eksponeringsterapi er en kort, beviset baseret indgriben for PTSD. Våd leveres generelt individuelt på tværs af 5 sessioner, hvor terapeuten guider patienten gennem skriveøvelser. På tværs af eksponeringssessioner oplever deltagerne habituation, så deres symptomer falder ved afslutningen af behandlingen. Wet har et etableret evidensbase i generel poliklinisk psykoterapi for PTSD, men er ikke blevet tilpasset eller testet i indstillinger for SUD -behandling. Desuden har efterforskerne tilpasset Wet til denne indstilling baseret på interessent og ekspert feedback.
Aktiv komparator: TAU
Treatment as Usual will include a variety of standard care services offered in short term residential treatment.
Behandling som sædvanlig vil omfatte en række standardplejetjenester, der tilbydes på kort sigt boligbehandling. For eksempel vil deltagere, der modtager TAU, deltage i individuel sagsstyring/generelle rådgivningssessioner med fokus på stofbrugsforstyrrelse og dens konsekvenser, gruppebaserede psykoeduceringssessioner, gruppebaserede rådgivningssessioner (f.eks. Planlægning af tilbagefald eller co-indgreb med en medicinsk udbyder og farmakoterapi (f.eks. Til tilbagetrækning, forebyggelsesforebyggelses- eller co-indgrebsbetingelser)

Foranstaltningsbeskrivelse
Tidsramme
PTSD symptom reduction
Tidsramme: Pre-WEST intervention; 4 weeks post-randomization, 8 weeks post-randomization, and 12 weeks post-randomization.
PTSD symptom reduction pre/post intervention by treatment arm as measured by he PTSD Checklist for DSM-5 (PCL-5) and the Clinician-Administered PTSD Scale for DSM-5 (CAPS). The PCL-5 is a 20-item self-report questionnaire that yields a total symptom scores ranging from 0-80 with higher scores indicating greater symptomology. The CAPS is a 30-item structured interview that yields a diagnosis of PTSD, a total PTSD symptom severity score, and a severity score for each symptom cluster.
Pre-WEST intervention; 4 weeks post-randomization, 8 weeks post-randomization, and 12 weeks post-randomization.
