简要总结
A Randomized Controlled Non-inferiority Trial testing if the new experimental Blended Trauma focused cognitive behavioral therapy (B-TF-CBT) for post traumatic stress disorder (PTSD), is non-inferior to gold standard control treatment Prolonged Exposure (PE).
Research question and hypothesis
Primary
- Is bTF-CT non-inferior to prolonged exposure (PE) when delivered in routine clinical care in terms of PTSD symptoms on the PCL-5 post-treatment?
Secondary: 2. Is bTF-CT non-inferior to prolonged exposure (PE) when delivered in routine clinical care in terms of PTSD symptoms on the PCL-5 at 6 and 12 months follow up? 3. Are there significant differences between bTF-CT and PE when delivered in routine clinical care in terms of depression, anxiety, insomnia, functionality, complex PTSD, other PTSD-measures and treatment satisfaction post-treatment and at 6 and 12 months follow up?
The study will be conducted at 3-6 outpatient clinics in Region Stockholm, Sweden.
详细描述
To study effects, the investigators aim to conduct a randomized controlled trial (RCT) comparing blended treatment to an evidence-based face-to-face TF-CBT protocol, Prolonged exposure.
Data will be collected concerning symptoms of PTSD with the PTSD Checklist for Diagnostic and Statistical Manual 5 (DSM-5; PCL-5) which will be the primary outcome measure. Further, symptoms of PTSD will be measured with Clinician-administered PTSD Scale for DSM-5 (CAPS-5), depression The PHQ-9, symptoms of anxiety with GAD-7 , quality of life with Work and social adjustment scale (WSAS), and sleep with the insomnia severity index (ISI). Outcome measures will be distributed before, during, after, as well as 12-months following treatment.
In accordance with CONSORT recommendations for non-inferiority trials, both intention-to-treat (ITT) and per-protocol (PP) analyses will be performed and reported for the primary non-inferiority comparisons. Secondary outcomes will be analyzed using ITT principles.
ITT population All randomized participants who completed the pre-treatment assessment and participated in the inclusion session.
PP population The PP population will include participants who have received at least 50% of the planned total treatment dose, defined across both digital modules and face-to-face sessions in the blended format.

研究组 & 干预措施
Blended Trauma focused Cognitive Behavioral Therapy (B-Tf-CBT)
B-Tf-CBT shares key features with Internet-based CBT (I-CBT) in that it is based on a digital support accessible to the patient. This digital support equips blended treatment with the same proposed advantages as I-CBT in terms of improving treatment accessibility, adherence, and reducing therapist-time. In addition, incorporating 6 biweekly face-to-face sessions to facilitate and augment delivery of more demanding components of TF-CBT such as memory exposure.
干预措施: Blended Trauma focused Cognitive Behavioral Therapy (B-Tf-CBT) (Behavioral)
Prolonged exposure
Gold standard Tf-CBT Prolonged exposure will constitute the control condition. Prolonged exposure will be delivered by trained therapists under supervision adhering to the evidence based manual delivered face-to-face over 9-15 weeks.
干预措施: Prolonged exposure (Behavioral)
