Short- and Long-Term Effectiveness of Brief Intensive Trauma Treatment for Adolescents With Posttraumatic Stress Disorder and Their Caregivers: Protocol for a Multicenter Randomized Controlled Trial.

backgroundChildhood trauma is pervasive, with approximately 50% of adolescents experiencing at least one potentially traumatic event before adulthood. Eight percent to 33% of potentially traumatic event-exposed adolescents develop posttraumatic stress disorder (PTSD), which can cause extreme suffering and coincides with numerous comorbid illnesses and high-risk behaviors. PTSD can be effectively treated in adolescents through weekly sessions of eye movement desensitization and reprocessing or trauma-focused cognitive behavioral therapy. Despite the availability of these treatments, numerous severely traumatized adolescents do not receive available treatment options due to high treatment avoidance. In adolescents who receive care, a large group of youth does not experience a sufficient symptom decrease after regular treatment. In addition, dropout rates during prolonged treatment are substantial, varying between 10% and 30%. This underscores the need for innovative and brief trauma treatment. Pilot studies indicate that Brief Intensive Trauma Treatment (BITT) can be a safe and effective treatment for adolescents with PTSD. However, randomized controlled trials on its effectiveness are crucial and urgently needed.

objectiveThis is the first study to test the effectiveness of a 1-week BITT in adolescents with PTSD and comorbid symptoms and their caregivers.

methodsThis multicenter, single-blinded randomized controlled trial will be conducted in 4 youth care centers in the European and Caribbean Netherlands: Levvel, Karakter, Fornhese-GGz Centraal, and Mental Health Caribbean (Bonaire). We will randomize adolescents (12-18 years old) with PTSD to a BITT (n=50) or waitlist control group (WLCG; n=50). BITT comprises 1-week (ie, 5 consecutive workdays) intensive trauma treatment, encompassing daily 90-minute manualized sessions of trauma-focused cognitive behavioral therapy and eye movement desensitization and reprocessing. The day begins and ends with psychomotor therapy. Caregivers receive daily parental counseling sessions consisting of psychoeducation and social support skill training. We will conduct measurements at similar intervals for both groups: at baseline; directly after BITT or WLCG; and at 3, 6, and 9 months' follow-up. The WLCG will receive BITT after the 3-month follow-up assessment. We will assess all study parameters using digital or face-to-face questionnaires and semistructured interviews. We will assess the primary outcome PTSD symptoms using the Child and Adolescent Trauma Screen 2 (CATS-2) and the Clinician-Administered PTSD Scale for DSM-5 (Diagnostic and Statistical Manual of Mental Disorders [Fifth Edition])-Child/Adolescent Version (CAPS-CA-5).

resultsAs of September 2022, we enrolled 104 participants. Data will be collected until December 2025. Results are expected to be published in the summer of 2026.

conclusionsThis first, innovative study on BITT's effectiveness may enhance treatment outcomes for PTSD by preventing dropout, reducing avoidance, shortening therapy duration, and empowering therapists by working together intensively. This research will provide valuable insights across cultures for treating severely traumatized adolescents who do not benefit sufficiently from regular treatment.
