In just 5 to 10 minutes, this convenient rating scale can identify individuals, between 3 and 23 years of age, who have attention-deficit/hyperactivity disorder. It is easily completed by teachers, parents, or others who know the referred individual.

    Based on DSM-IV criteria for attention-deficit hyperactivity disorder, the test is composed of 36 items and 3 subtests: Hyperactivity, Impulsivity, Inattention.

    Raw scores for these subtests are converted to percentiles and standard scores. A full-scale percentile rank and an overall ADHD quotient are also provided. Norms--collected on a national sample of 1,200 people diagnosed with ADHD--are presented separately for males and females.

    Carefully constructed and psychometrically sound, this test can be used with confidence to identify students who have ADHD, to evaluate children referred for behavior problems, and to determine appropriate intervention.
