What this Trial Is About
Researchers are studying the PTSD-iMPACT questionnaire, a new tool designed to measure how post-traumatic stress symptoms affect daily functioning in children and adolescents aged 3 to 18 years. The study aims to validate this tool in both clinical and non-clinical populations in Switzerland and Germany. It addresses a need for a reliable, detailed measure of PTSD-related impairments across areas like family, school, friendships, hobbies, and media use. The study involves collecting data from trauma-exposed children, adolescents, and their caregivers through self-report and caregiver-report versions of the PTSD-iMPACT. Participants complete questionnaires at baseline and again two weeks later for test-retest reliability. Data collection occurs in clinical settings and schools, with some assessments completed online or via phone/video calls. The study is conducted over 13 months and includes both German-speaking clinical populations and a non-clinical sample in Switzerland. Participants provide information on trauma exposure, PTSD symptoms, depression, anxiety, quality of life, and emotional regulation, among other measures. The study uses statistical analyses to assess the reliability and validity of the PTSD-iMPACT tool. Participants in clinical groups complete two assessments, while non-clinical participants complete one. Study involvement includes completing questionnaires online or in person with support provided as needed, ensuring confidentiality and voluntary participation throughout the study.
