The five most commonly used ratings scales for the assessment of Attention Deficit Hyperactivity Disorder (ADHD) were evaluated in terms of the purpose of the scale, the standardization sample and norms and evidence of reliability and validity. ADHD is one of the most common referrals, and rating scales are one of the primary components in the preliminary assessment.
The rating scales with the strongest standardization samples and evidence of reliability and validity were the ADHD Rating Scales IV (ADHD-IV), the Attention Deficit Disorders Evaluation Scales (ADDES), and the Connors Rating Scales-Revised (CRS-R). The Connors Scale is the most comprehensive measure, and evaluators recommended its use particularly if the user is interested in assessing a broad range of behaviors. The ADDES is the only scale that links deficits to specific interventions. Two other scales, the Attention Deficit/Hyperactivity Disorder Test (ADHDT) and the ADD-H: Comprehension Teacher’s Rating Scales (ACTeRS) are not recommended for use, since both were judged to lack important information in their manuals and to present only limited evidence of reliability and validity.
