OBJECTIVES To understand social and work impacts of caring for children/adolescents with attention-deficit/hyperactivity disorder (ADHD) in Sweden relative to a combined cohort of other Nordic countries (Denmark, Finland and Norway). METHODS Carers in Sweden and other Nordic countries completed the Caregiver Perspective of Pediatric ADHD (CAPPA) online survey capturing carer impacts, including work, social activities and family relationships, due to their child’s ADHD. Impacts were explored when the child was “on” and “off” medication (e.g. days medication not taken). Comparisons of “on” and “off” medication were examined using the Wilcoxon Signed-Rank test. No statistical comparisons of impacts were made between countries. RESULTS
