Attention-Deficit Hyperactivity Disorder (ADHD)
Attention-Deficit/Hyperactivity Disorder (ADHD) is characterized by inattention,
hyperactivity, and impulsivity that lasts at least six months, is present in more than one
environment, and is developmentally inappropriate (American Psychiatric Association,
1994). ADHD is typically diagnosed in childhood when a concerned parent or teacher refers
the child for evaluation after noticing that the child's inattention, hyperactivity, or
impulsivity is having an adverse impact on academic performance, socialization, or
compliance with limits set by adults. Children with ADHD may be primarily inattentive,
primarily impulsive or hyperactive, or may show a combination of these features. Children
with primarily hyperactive/impulsive type ADHD often display symptoms in the preschool
years, while the primarily inattentive type ADHD may go unnoticed until the school age
years or even later (Blum & Mercugliano, 1997). The American Psychiatric Association
(1994) estimates that about 3% to 5% of school-age children have ADHD, with a male to
female ratio of 4:1-9:1. Treatment of ADHD usually involves medication such as
methylphenidate (Ritalin) and ongoing behavioral management. Research suggests that many
children with ADHD benefit considerably from a combination of these two approaches. For
