Brief Summary
The goal of this clinical trial is to compare a novel, massed treatment format of prolonged exposure to gold standard trauma focused cognitive behavioral therapy (weekly delivered prolonged exposure) for post-traumatic stress disorder. The objective with this study is to investigate efficacy, mechanisms of change and cost effectiveness of intensive prolonged exposure (I-PE) in regular Swedish psychiatric care. Adult patients with post-traumatic stress disorder will be randomly assigned to receive either gold standard prolonged exposure weekly for 15 weeks or 5 days of intensive treatment with the addition of three booster sessions dispersed 1, 2 and 4 weeks after completion of the massed treatment period.

Outcome Measures
Primary Outcomes (1)
Change in PTSD symptoms as assessed by the Clinician Administered PTSD Scale (CAPS-5)
The CAPS-5 is structured interview that assesses the Diagnostic and Statistical Manual of Mental Disorders version 5 (DSM-5) criteria for PTSD (Weathers et al., 2013). Each item is rated on a severity scale ranging from 0 (Absent) to 4 (Extreme/incapacitating) and combines information about frequency and intensity for each of the 20 symptoms. Total Score (Range 0-80 with higher scores representing more PTSD symptoms.
Baseline, 1-month (primary endpoint), 6-month and 12-month post-treatment
Secondary Outcomes (10)
Change in PTSD symptoms as assessed by the PTSD Check List - DSM-5 (PCL-5)
Baseline, through the treatment period up to 15 weeks after inclusion and at 1-month, 6-month and 12-month post-treatment
Change in ICD-11 PTSD and complex PTSD symptoms as assessed by the International Trauma Questionnaire (ITQ).
Baseline, through the treatment period and 1-month, 6-month and 12-month post-treatment
Change in depressive symptoms as measured by the Patient Health Questionnaire-9 (PHQ-9)
Baseline, immediately after treatment completion, 1-month, 6-month and 12-month post-treatment
Change in quality of life measured by Euroqol, EQ-5D
Baseline, immediately after treatment completion, 1-month, 6-month and 12-month post-treatment
Change in Assessing Quality of Life 6 Dimensions (AQoL-6D)
Baseline, immediately after treatment completion, 1-month, 6-month and 12-month post-treatment
- +5 more secondary outcomes
Other Outcomes (4)
