Learning by Heart: The Effectiveness of an EF Training Program for Pre-schoolers With a Severe CHD — LbH  

Congenital Heart Disease Clinical Trial

Official title: The Effectiveness of a Personalized Executive Functioning Training Program for Pre-schoolers With a Severe Congenital Heart Disease

Status Not yet recruiting

Clinical Trial Summary

Advances in prenatal and neonatal care have improved outcomes in children with severe congenital heart disease (CHD). With the increase in survival, neurocognitive problems such as executive functioning (EF) impairments have become more apparent in these children. EF problems have cascading negative effects on a child's development. New insights in EF development suggest that in otherwise physically healthy young children, EF can be improved by training. In a pilot study funded by Stichting Hartekind, the investigators studied the feasibility of a personalized EF training program called 'Kleuter Extra' and the results were promising. Therefore, the current study will investigate the effectiveness of this program in 4-6-year-old children with severe CHD. The researchers will also explore interactions between the parent-child relationship and EF development of the child as psychosocial difficulties in these children and their parent(s) and/or caretaker(s) may impact EF-development. If found effective, EF training for children with severe CHD will improve their developmental outcome.

Clinical Trial Description

Advances in prenatal and neonatal care have improved outcome in children with severe congenital heart disease (CHD), with survival rates up to 90%. With the increase in survival, neurocognitive problems and psychological maladjustment have become more apparent in these children, such as impairments in their executive functioning. Executive functioning (EF) is an umbrella-term for several higher-order cognitive processes crucial for self-regulated and goal directed behaviour. Frequently postulated components of EF are inhibition, including motor inhibition, and attention, working memory, and cognitive flexibility. Early EF problems often result in emotion regulation difficulties, behavioural problems, social problems, and learning problems, which can lead to diminished functioning in social domains and lower achievement levels in education and employment status. Children with CHD might be rendered even more vulnerable for EF-problems since EF development is embedded within the social context of a child. There is an increasing understanding of how naturally distressing the CHD diagnosis and treatment can be for parents, which can impair the interactions with their child and in turn might negatively impact the child's EF development. Looking at the reciprocal nature of relationships, the child's illness and/or emotional and behavioural problems that may be associated with EF difficulties might negatively impact the parent-child relationship, parenting behaviour and parental wellbeing. However, these relations are poorly understood, especially regarding fathers. A greater understanding of the interplay between biological and psychosocial factors on EF-development is needed to promote optimal developmental outcomes for these vulnerable children. New insights suggest that EF can be improved by training. Due to neural plasticity, the window for effective training seems to be between the ages of two and six years. After this time frame, improvements in EF may not retain after training or not generalize to off-task functions. Current EF training programs are not personalised ('adaptive') but offer the same program regardless of the specific child's EF dysfunctions, which may explain their limited effects. There is presently no effective EF training program for children with CHD. In a pilot study funded by Stichting Hartekind, the researchers investigated the feasibility of a personalised EF training program called 'KleuterExtra' in 4-6 year old children with severe CHD. Within a week, 31 children were (self-) referred for the study, indicating a great clinical need. Directly after training, children showed clinically relevant improvement on the specific EFs targeted in training, with Cohen's d effect sizes ranging from 0.19 to 2.41 (>1.00 on 5 out of 9 tasks). Improvement was also found in untrained EFs and tasks that combined multiple EFs, indicating a generalization effect. Parents and teachers spontaneously reported positive results in daily life. Based on these promising results, the investigators designed the current randomized, controlled study to test the effectiveness of this training program in pre-schoolers with severe CHD. Given the above, the investigators designed this study to investigate the effectiveness of a tailored EF training program for preschoolers with severe CHD. Secondary aim was to explore interactions between the parent-child relationship and the EF development of the child. If found effective, EF training for children with severe CHD will improve their developmental outcome. ;
