Julia Waage is developing an interview for children aged four and older that captures their participation situation and wishes, with a focus on early intervention. The foundation of this work is the ICF-CY (WHO 2007, German translation: DIMDI 2011), specifically the "ICF-CY Checklist for Children and Adolescents (3-6)" created by the German interdisciplinary working group for ICF adaptation in the field of children and youth (2012). Assessing children's participation in line with the ICF philosophy requires the direct involvement of the child. The interview is being tested with three five-year-old boys who are receiving early intervention. The children predominantly answer the interview questions appropriately, which supports the comprehensibility of the questions and the use of interviews to assess participation in this area.
