cbits - treat trauma in child welfare

Conditions: Posttraumatic Stress Disorder

Summary: the goal of this randomized controlled trial is to evaluate the effectiveness of the trauma-focused group intervention cbits compared with enhanced treatment as usual (tau+) in child welfare programs in germany. the target group are traumatized children and adolescents in out-of-home care who report posttraumatic stress symptoms (ptss).

the study objectives are 1. evaluate the effectiveness of cbits compared to tau+ regarding ptss symptom reduction (primary outcome), anxiety, depression, quality of life and functional level, and continuance of the child welfare program (secondary outcomes) at 4-month follow-up 2. investigate potential long-term effects of the treatment in the cbits condition regarding the primary and secondary outcomes at 10-month follow-up. 3. implement cbits as an outreach intervention into routine mental health care for traumatized children, to evaluate treatment fidelity, treatment completion and investigate different potential individual or structural factors that might have an impact on the implementation. 4. to assess the readiness in child welfare programs to collaborate with mental health services and the role of institutional environments for developmental trajectories. participants and their caregivers will complete questionnaires at three measurement time points. weekly ptss symptom monitoring during treatment and alliance ratings (participants and therapists) at the beginning and the end of the intervention will be implemented. trained therapists at three study centers (marburg, ulm, bochum) will complete questionnaires before their training and after cbits implementation. site monitoring and auditing, as well as reliability checks of the data will be conducted by an independent data manager. randomization will be implemented by an independent institute at ulm university. standard operating procedures (sops) to address patient recruitment, data collection, data management, reporting for adverse events, and change management will be provided. sample size assessment to specify the number of participants or participant years necessary to demonstrate an effect were performed via the program g-power, in collaboration with an independent statistical advisor, before proposal submission. a plan for missing data to address situations where variables are reported as missing, unavailable, non-reported, uninterpretable, or considered missing because of data inconsistency or out-of-range results are prepared in collaboration with the independent statistical advisor. we will following intention-to-treat (itt) principles in our analyses. the statistical analysis plan describing the analytical principles and statistical techniques to be employed in order to address the primary and secondary objectives, are specified in the study protocol which will be published before data collection.

Eligibility criteria:
inclusion criteria: 1. age 8-16 years, because this age range reflects the age range in the cbits evaluation studies, and this age range is specified in the cbits manual and toolkit). 2. having experienced at least one traumatic event (based on dsm-5 or icd-10/icd-11 criteria) as cbits is designed for children and adolescents with a trauma history. 3. at least moderate ptss (at least 21 points on the cats-2) as this is recommended in the intervention manual. participants don't have to fulfill ptsd criteria as the manual does not name this a pre-condition for participation. additionally, there is large evidence that also youth with subthreshold ptss show high functional impairment, but respond very well to trauma-focused interventions. 4. being currently cared for by a child welfare program (safe and stable living conditions), planned further stay in the program for at least 12 months in order to complete the cbits intervention and 10-month follow-up. 5. willingness and informed assent/consent of the participant as well as informed consent of the caregiver/legal guardian to participate in the study (sufficient motivation for group intervention and compliance with the study design). exclusion criteria: 1. current psychosis for safety reasons and in because in this case another intervention another intervention has priority (same explanation for 2-4). 2. severe harm to self or others 3. severe substance disorder 4. acute suicidality 5. severe mental retardation as there is a certain necessity of sufficient cognitive abilities to benefit from cbits, to recall trauma memories and to create a trauma narrative.
