Abstract
The ADHD Rating Scale-IV is a screening instrument designed to assess attention-deficit/hyperactivity disorder in children. It is comprised of 18 items and has both a home and school version for parents and teachers to complete, respectively. A sample consisting of 178 parent-teacher dyads of children aged 6-12 years of age participated in the study. Psychometric investigation of these scales revealed high internal consistency, adequate test-retest reliability, and appropriate correlations with other measures of ADHD. Principal components factor analysis revealed two factors for both scales: (1) Inattention-hyperactivity and (2) Impulsivity-hyperactivity. Discriminant function analyses and base rate analyses revealed that these scales can correctly separate true ADHD children from normal controls but that it has significant difficulty differentiating other clinical populations. It was concluded that both scales have psychometric properties strong enough to be used as a screening measure.
