Hyperactivity is now classified as attention deficit disorder (ADD) or attention-deficit hyperactivity disorder (ADHD).
The primary purpose of the study was to investigate genetic, environmental (e.g., teasing by peers, parent-adolescent relationships), and neurobiological (i.e., gonadal hormones) risk factors for disordered eating, antisocial behavior, mood, attention/hyperactivity problems, and temperament during early adolescence.
