The purpose of this study was to examine the existing research on the psychological distress experienced by parents whose young children (between the ages of 0 and 5 years old) have a congenital heart defect (CHD). A more detailed understanding of the distress experienced by these parents, including stress associated with the child's age, the severity of the child's diagnosis, and parent characteristics, is vital as it would allow for more targeted and individualized support for this population to enhance parental coping strategies and increase the likelihood of more positive parent-child interactions. This review of 25 studies contributes to the parenting stress literature by focusing on parents of young children and categorizing studies by publication characteristics, research methodology, and findings. The research clearly demonstrates that parents report a great deal of stress throughout the continuum of their child's health care experience. Recommendations for future research and practice implications, such as developing a stress vulnerability model specific to parenting children with CHD, clarifying the role between interdisciplinary team members regarding provision of psychosocial support to parents, and referring parents to specific community-based ongoing social support services, are presented.
