Attention-Deficit/Hyperactivity Disorder

Attention-Deficit/Hyperactivity Disorder (ADHD) is a disruptive behavior disorder that describes individuals who engage in developmentally inappropriate levels of inattention, impulsivity, or overactivity (American Psychiatric Association, 2000). Approximately 3 to 7% of school-aged children in the United States can be diagnosed with this disorder, representing approximately one child in every classroom (American Psychiatric Association, 2000; Barkley, in press; DuPaul & Stoner, 2003). Boys outnumber girls with this disorder at approximately a 2:1 to 6:1 ratio (Barkley, in press). Typically, ADHD is a chronic disorder that extends into adulthood for the majority of affected individuals (Barkley, Fischer, Smallish, & Fletcher, 2002).
