Is this trial a fit for you?
✓Likely a good fit
Adolescents aged 12–18 with DSM-5 Criterion A trauma (after age 3), a CATS-2 total score ≥25, a nonoffending caregiver willing to join weekly TF-CBT sessions, stable/safe living circumstances, and sufficient German language skills are ideal candidates.
✕Probably not a fit
Patients without significant PTSS, without a available nonoffending caregiver, unable to attend weekly in-person sessions, living in unsafe/unstable conditions, or lacking sufficient German language ability are unlikely to benefit or be eligible.

What this trial studies
This observational project follows adolescents aged 12–18 with high post-traumatic stress symptoms as they receive trauma-focused cognitive behavioral therapy (TF-CBT) based on Cohen, Mannarino, & Deblinger (2017). Symptoms are measured repeatedly over the course of weekly TF-CBT sessions, with eligibility requiring a baseline Child and Adolescent Trauma Screen 2 (CATS-2) score of ≥25. The study uses single-case longitudinal analyses to capture individual patterns of symptom change rather than relying solely on group averages. A nonoffending caregiver participates in weekly sessions as part of the TF-CBT model, and all treatment occurs at the University Children's Hospital Zurich.
Why it matters
Potential benefit: If successful, the project could clarify typical and individual symptom trajectories during TF-CBT, helping clinicians personalize care for adolescents with post-traumatic stress symptoms.
How similar studies have gone: TF-CBT is an established, evidence-based treatment that has reduced PTSD symptoms in youth, though single-case longitudinal tracking of individual symptom changes is less commonly reported.
Who can join: the full rules
Show full inclusion / exclusion criteria
Participants will be included if: 1. they are between 12 and 18 years of age; 2. they have been exposed to at least one or more traumatic event(s) according to the DSM-5 A criteria after the age of 3 years and dating back at least 1 months (with regard to the ability of patients to remember the event(s) and to the high spontaneous remissions of PTSS in the first month after a traumatic event); 3. they exhibit high severity of DSM-5 PTSS as indicated by a total symptom score of ≥25 assessed with the Child and Adolescent Trauma Screen 2 (CATS-2); 4. a nonoffending adult caregiver is available for the treatment and willing to participate in weekly treatment sessions (the inclusion of a caregiver is integral to the TF-CBT treatment model); 5. they are willing and able to attend weekly treatment sessions; 6. if their living circumstances are safe and stable to minimize the risk of re-traumatization during the project; 7. they and their caregiver have sufficient command of the German language (i.e., to participate in assessment \[read\] and treatment\[converse\]); 8. they and their caregivers possess a smartphone. 9. they and their caregiver provided written informed consent. Participants will not be included if: 1. they exhibit acute suicidal behavior or have suicidal ideations requiring immediate hospitalization; 2. they have a documented developmental disorder (i.e., autism spectrum disorder) or current psychosis based on adolescent- and caregiver-report and clinical assessment; 3. they exhibit severe substance misuse based on clinical assessment; 4. take part in concurrent psychotherapy during TF-CBT; 5. exhibit severe intellectual disability based on clinical assessment.
