Abstract
The purpose of this study was to examine the relationship among selected demographic and psychosocial family characteristics and family functioning and to identify which combination of variables best predicts family functioning when a child has attention deficit disorder. Seventy-six mothers and 47 fathers from 79 families participated in the study. The target child had been previously diagnosed with attention deficit disorder either with or without hyperactivity and aggressive symptoms. A significant correlation between family functioning and age of the hyperactive child was supported. Families of older children reported poorer functioning, and parenting competence was negatively related to parental perception of the child's behavior. Older age of the child in combination with higher levels of impulsivity/hyperactivity were significant in predicting family functioning.
