The ADHDT-2 Helps Teachers, Parents, and Clinicians Identify ADHD in Individuals and Estimate its Severity
Features and benefits
- Based on the 2013 diagnostic criteria for ADHD adopted by the APA and published in the DSM-5™.
- Yields standard scores, percentile ranks, severity levels, and probability of ADHD.
- Has 33 clearly stated items that describe the characteristic behaviors of persons with ADHD; the items are grouped into two subscales: Inattention and Hyperactivity/Impulsivity.
- Both subscales and the ADHD Index have been empirically determined to be valid and sensitive for identification of children with ADHD.
- All-new normative data were collected in 2013 on a sample of 1,591 examinees diagnosed with ADHD.
- All-new validity studies show that the test results are valid for a wide variety of subgroups, as well as for the general population.
- Diagnostic accuracy studies indicate that the ADHDT-2 is able to discriminate children with ADHD from typical children without ADHD (sensitivity = .90, specificity = .82, ROC/AUC = .95).
