What this trial studies

This study investigates the effectiveness of a personalized executive function training program called 'Kleuter Extra' for children aged 4-6 years with severe congenital heart disease (CHD). The program aims to improve executive functioning skills, which are crucial for self-regulation and goal-directed behavior. The study also explores the impact of the parent-child relationship on the child's executive function development, considering the psychosocial challenges faced by families dealing with CHD. Participants will be assessed using a test battery to determine their eligibility based on executive function scores. The study is conducted at multiple medical centers in the Netherlands.

Who should consider this trial

Good fit: Ideal candidates are children aged 4-6 years with a history of severe congenital heart disease requiring surgery in infancy and demonstrating diminished executive function.

Not a fit: Patients who do not have congenital heart disease or those with moderate to severe intellectual disabilities may not benefit from this study.

Why it matters

Potential benefit: If successful, this program could enhance cognitive and emotional development in preschoolers with severe CHD, leading to better long-term outcomes.

How similar studies have performed: Previous pilot studies have shown promising results for similar executive function training approaches in young children.
