ABSTRACT
Attention deficit hyperactivity disorder (ADHD) is a disruptive behavior disorder that describes individuals who engage in developmentally inappropriate levels of inattention, impulsivity, and/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, 2006; DuPaul & Stoner, 2003). Boys outnumber girls with this disorder at approximately a 2:1 to 6:1 ratio (Barkley, 2006). Typically, ADHD is a chronic disorder that extends into adulthood for the majority of affected individuals (Barkley, Murphy & Fischer, 2008).
