“Barkley is one of the leading scientists in ADHD. With this rating scale, he continues to advance our scientific understanding of the assessment of this disorder.”

—Lenard Adler, MD, Department of Psychiatry and Director, Adult ADHD Program, New York University School of Medicine


“The BAARS-IV is a valuable addition to the assessment process for ADHD in adults. Barkley has created a valid and reliable tool that will greatly aid in the diagnostic and differential diagnostic process for ADHD. I will definitely include this current, comprehensive scale in my adult assessments, and I encourage other clinicians to do the same.”

—Sam Goldstein, PhD, Department of Psychiatry, University of Utah School of Medicine; Clinical Director, Neurology, Learning, and Behavior Center, Salt Lake City


“Based on DSM-IV criteria, and normed on a large, representative sample of the adult population, the BAARS-IV will increase the reliability and validity of diagnoses of ADHD in adults. In addition to the self-reports of current and childhood symptoms, the BAARS-IV includes other-report forms and a quick screening tool. The development and validation of this scale and its presentation in the manual reflect Barkley’s usual impeccable work and his extensive clinical and research experience with ADHD.”
