However, retention in PTSD EBPs is poor. Premature dropout is associated with worse clinical outcomes and greater healthcare utilization. Delivery of PTSD EBPs in a massed format, typically three or more days per week delivered within a month, have shown promise for increasing retention. The present study is a pilot feasibility and acceptability study comparing massed PTSD treatment to treatment as usual (e.g., typically weekly treatment)., conditionsModule conditions: Stress Disorders, Post-Traumatic, designModule studyType: INTERVENTIONAL, phases: NA, designInfo allocation: RANDOMIZED, interventionModel: PARALLEL, interventionModelDescription: Massed PTSD treatment (e.g., cognitive processing therapy \[CPT\] or prolonged exposure \[PE\] therapy delivered at least 3 times per week) will be compared to CPT \& PE delivered as usual, which is usually once per week., primaryPurpose: TREATMENT, maskingInfo masking: SINGLE, maskingDescription: Clinical interviewers who assess primary outcomes will not be informed of participant's randomization assignment., whoMasked: OUTCOMES_ASSESSOR, enrollmentInfo count: 30, type: ESTIMATED, armsInterventionsModule interventions name: EBP-Massed, interventions name: EBP-TAU, outcomesModule primaryOutcomes measure: Treatment completion, primaryOutcomes measure: Acceptability of Intervention (AIM), primaryOutcomes measure: Client Satisfaction Questionnaire-8 (CSQ-8), primaryOutcomes measure: Clinician Administered PTSD Scale for DSM-5 (CAPS-5) Severity Score, primaryOutcomes measure: Clinician Administered PTSD Scale for DSM-5 (CAPS-5) Severity Score, secondaryOutcomes measure: Session attendance, secondaryOutcomes measure: Patient Health Questionnaire-9 (PHQ-9), secondaryOutcomes measure: Patient Health Questionnaire-9 (PHQ-9), secondaryOutcomes measure: Brief Inventory of Psychosocial Functioning (BIPF), secondaryOutcomes measure: Brief Inventory of Psychosocial Functioning (BIPF), eligibilityModule sex: ALL, minimumAge: 18 Years, stdAges: ADULT, stdAges: OLDER_ADULT, contactsLocationsModule locations facility: Durham VA Medical Center, Durham, NC, city: Durham, state: North Carolina, zip: 27705-3875, country: United States, contacts name: Stephanie Y Wells, PhD MS BA, role: CONTACT, phone: 919-286-0411, phoneExt: 134053, email: stephanie.wells2@va.gov, contacts name: Laurel B Koss, MS OTR, role: CONTACT, phone: (919) 286-0411, phoneExt: 775648, email: laurel.koss@va.gov, contacts name: Stephanie Y Wells, PhD MS BA, role: PRINCIPAL_INVESTIGATOR, geoPoint lat: 35.99403, lon: -78.89862, hasResults: False
