The translation complied with the international guidelines. Reproducibility was assessed in 53 children (15 years) responding Pedi\u2010<jats:styled-content style=\"fixed-case\">IKDC<\/jats:styled-content> at baseline and after 3\u201314 days. For analysis of responsiveness, 94 children (15 years) responded Pedi\u2010<jats:styled-content style=\"fixed-case\">IKDC<\/jats:styled-content> again after 3 months. Test\u2013retest reliability was excellent. Intraclass correlation coefficient was 0.9, standard error of measurement was 4.1 points, and smallest detectable change (<jats:styled-content style=\"fixed-case\">SDC<\/jats:styled-content>) was 11.3 points. Evaluating responsiveness as a large effect was found in children reporting improvement compared with children reporting deterioration.
