The impact of maternal perceptions and medical severity on the adjustment of children with congenital heart disease.

Hypothesized that maternal perceptions would be more significant predictors of emotional adjustment than medical severity. Mothers of 99 children, between the ages 4-10 years, completed the Child Behavior Checklist, Parenting Stress Index, Parental Locus of Control Scale, and a measure of perception of medical severity. Assessed medical severity by number of hospitalizations, operations, catheterizations, hospital days, outpatient visits, and a cardiologist's rating of illness severity. Maternal perceptions were potent predictors of emotional adjustment. Approximately 33% of the variability in adjustment was accounted for by maternal perceptions, while the medical severity accounted for less than 3% of the variability. Severity of illness appears less critical to successful adaptation than the quality of the mother-child relationship.
