This study will invite parents of children who underwent surgical treatment for congenital heart disease to complete a validated proxy-report questionnaire assessing executive and psychosocial functioning. The instrument used will be the French version of the Strengths and Difficulties Questionnaire (SDQ), validated for children aged 6-17 years, which evaluates cognitive, executive, and mental health domains and provides both global and subdomain scores.
After a telephone explanation, the questionnaire will be sent to parents of eligible children aged 6-18 years and returned by post once completed. This methodology is modeled on follow-up networks for vulnerable newborns, where parent-completed questionnaires are completed at home and mailed back.
