Parents of all patients diagnosed with complex congenital heart disease requiring hospitalization or intervention during the neonatal period will be eligible to participate. Parents unable to speak or read English will be excluded. An attempt will be made to obtain consent for participation from both the mother and father of the affected infant. If no father is involved in the care of the infant, measures will be obtained from mothers alone. The model will be tested using mothers' reports of family variables. Single parents will be able to participate but will not be included in comparisons between mothers and fathers. Nurse coordinators at participating centers will conduct subject screening and consenting.
