PTSD-iMPACT: measuring how PTSD affects daily functioning in children and adolescents

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The study is a multi-center observational validation of the PTSD-iMPACT conducted in Switzerland and Germany. Development followed two phases: a systematic review that identified gaps in existing instruments, and qualitative interviews and focus groups with trauma-exposed children, adolescents, and caregivers to generate items and domains. The validation will recruit clinical participants (children/adolescents 7–18 and caregivers of children 3–18) and school-based non-clinical samples in Switzerland, using German-language measures and informed consent procedures. Psychometric analyses will examine domain structure, scoring, reliability, and validity across settings.
