Investigators provided item-specific weightings. Quantitative and qualitative data were integrated.ResultsThe analysis showed moderate satisfaction overall. Strengths included clarity in describing the trial purpose and risks/benefits. Key deficiencies were found in accessibility features such as audiovisual aids, and simplified language. Investigators prioritized technical accuracy, while KIDS emphasized clarity, structure, and engagement. Gaps were identified in adherence to existing guidelines, especially regarding document length, readability, and support resources.DiscussionThere is a clear mismatch between investigators’ focus and young patients’ needs. While technical content was generally adequate, critical elements for child comprehension were lacking. These findings support the need to involve YPAGs to improve pediatric assent documents.
