Abstract

Attention deficit/hyperactivity disorder (AD/HD) is one of the most commonly studied and diagnosed psychiatric disorders in children. Behavior rating scales are often utilized in the assessment and treatment monitoring for AD/HD. This study investigated the testretest reliability of the ADD-H Comprehensive Teacher's Rating Scale 2nd Edition (ACTeRS-2). The ACTeRS-2 rating scale is comprised of four behavior subscales, which include conduct areas frequently displayed by children with AD/HD. The subscales consist of Attention, Hyperactivity, Social Skills, and Oppositional behavior items. For the purpose of this study, data were collected on 124 students in third, fifth, and sixth grade who attended public schools in Central Illinois. ACTeRS-2 rating scales were used to gather information on the subjects through teacher rating forms. Results indicated that test-retest correlations for the Attention (r =.87), Hyperactivity (r =.87), and Social Skills (r =.80) subscales of the ACTeRS-2 yielded correlations that fell within the moderate range of test-retest reliability. The Oppositional (r =.63) subscale test-retest results, however, revealed low reliability. Results and implications of the study are discussed.
