Preliminary Examination of the Reliability and Concurrent Validity of the Attention-Deficit/Hyperactivity Disorder Self-Report Scale v1.1 Symptom Checklist to Rate Symptoms of Attention-Deficit/Hyperactivity Disorder in Adolescents

The ASRS v1.1 Symptoms Checklist showed high internal consistency and high concurrent validity with the clinician-administered ADHD-RS in adolescents with ADHD. Results of this study suggest that the ASRS v1.1 Symptom Checklist is an internally consistent self-report scale for the assessment of adolescent ADHD and is moderately associated with a concurrently administered clinician measure of ADHD symptoms.
