Insights
Parents of children with hypoplastic left heart syndrome (HLHS) experience significantly higher parenting stress and report more child behavior problems compared to controls. Children with other univentricular heart defects (UVH) did not show increased stress or behavioral issues.
Area of Science:
- Pediatric Cardiology
- Developmental Psychology
- Neurodevelopmental Disorders
Background:
- Hypoplastic left heart syndrome (HLHS) is a severe congenital heart defect.
- Understanding the psychosocial impact on families is crucial for comprehensive care.
- Previous research has explored neurodevelopmental outcomes, but parental stress and child behavior require further investigation.
Purpose of the Study:
- To assess child behavior and parenting stress in parents of young children with HLHS.
- To compare these perceptions with parents of children with other functionally univentricular heart defects (UVH) and healthy controls.
- To identify specific areas of concern related to these conditions.
Main Methods:
- Prospective, nation-wide neurodevelopmental follow-up study.
- Inclusion of parents of 23 HLHS patients, 14 UVH patients, and 46 healthy controls (mean age 18 months).
- Utilized Child Behavior Checklist and Parenting Stress Index questionnaires.
Main Results:
- Significantly higher total parenting stress reported by mothers and fathers of HLHS patients compared to controls.
- Parents of HLHS patients reported more total and internalizing child behavior problems, particularly somatic complaints.
- No significant increase in parenting stress or emotional problems was found in parents of UVH patients compared to controls.
Conclusions:
- HLHS significantly increases parenting stress.
- Emotional maladjustment in children with HLHS may be partly linked to somatic complaints.
- These findings highlight the need for targeted psychosocial support for families affected by HLHS.
Aims:
To assess perceptions of child behaviour and parenting stress among the parents of young children with hypoplastic left heart syndrome (HLHS) and other forms of functionally univentricular heart defects (UVH).
Methods:
As part of our prospective nation-wide neurodevelopmental follow-up study, the parents of 23 patients with HLHS, 14 with UVH and 46 healthy controls at the mean age of 18 months received the questionnaires Child Behavior Checklist and Parenting Stress Index.
Results:
The reported level of total parenting stress was significantly higher among the mothers (mean score 241 vs 205, p < 0.001) and fathers (235 vs 202, p = 0.003) of patients with HLHS compared with those of controls. The parents of patients with HLHS reported significantly more total (mean T score 52 vs 45, p = 0.005) and internalizing (51 vs 41, p < 0.001) behaviour problems than the controls, but among the syndrome scales, a significant difference was only found in somatic complaints. The parents of patients with UVH did not report more parenting stress or emotional problems than the controls.
Conclusion:
Hypoplastic left heart syndrome, a severe congenital heart defect, increases parenting stress. The reported emotional maladjustment in affected children might in part be owing to somatic complaints.

Parenting Styles
Authoritarian Parenting
This style is strict and controlling, with little room for open dialogue. Authoritarian parents demand obedience and often enforce rules with minimal warmth. Children raised this way may lack social skills and initiative, usually comparing themselves to others unfavorably.
