Abstract
The purpose of this study was to describe adaptability, cohesion, and family type in families of boys with attention deficit disorder. Comparisons were made across diagnostic groups for boys with and without hyperactivity and aggressive symptoms. Parents (N = 123) of 79 boys with attention deficit disorder (ADD), attention deficit hyperactivity disorder and attention deficit hyperactivity disorder plus aggressive symptoms participated in the study. The families were not significantly different in their functioning when compared to family norms established by Olson, Portner, and Lavee (1985). There were, however, significant differences in functioning across diagnostic categories. Parents of boys with ADD only, without the additional problem of hyperactivity or aggressive symptoms, reported the highest level of family functioning, and a larger percentage of parents whose child had hyperactivity or hyperactivity plus aggression reported extreme family functioning.
