Attention Deficit and Hyperactivity Disorder Test (ADHDT-2)

BY JAMES E. GILLIAM

The Attention-Deficit/Hyperactivity Disorder Test, Second Edition (ADHDT-2) helps clinicians and teachers quickly identify ADHD in students and estimate its severity. It meets diagnostic criteria for ADHD published in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5).

Thirty-three clearly stated items are grouped into two subscales—Inattention and Hyperactivity/Impulsivity—and describe the characteristic behaviors of individuals with ADHD. The Examiner’s Manual provides evidence that the ADHDT-2 provides a reliable and valid measure of ADHD in children and adolescents.
