“Reliable, empirically based, and convenient to use for clinicians. Allow[s] a doctor to quantify behaviors that can't be readily observed in the clinic.”

—ADDitude Magazine


“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.”

—Mary V. Solanto, PhD, Department of Pediatrics and Department of Psychiatry, Zucker School of Medicine at Hofstra/Northwell

The BAARS–IV is based on more than 16 years of research by the developer using prototypes of the BAARS–IV. The large normative sample (N>1,200) is representative of the U.S. population in terms of region, socioeconomic status, education, ethnicity/race, and gender, based on the 2000 U.S. Census. Scoring sheets present norms for three age groups of adults (18–39, 40–59, and 60–89 years old).

Reliability
Reliability of the scores is quite satisfactory as evidenced by high internal consistency (Cronbach's alpha of .92 for current ADHD and .95 for childhood ADHD symptom scores); good interobserver agreement (.67 to .70 across scales); and high test–retest reliability over a 2–3 week interval (.75 for current ADHD and .79 for childhood ADHD symptom scores).

Validity
Validity of the scale scores was evident in numerous analyses, including factor analyses; correlations with other measures of ADHD symptoms; and correlations, regression analyses, and group comparisons concerning disorder discrimination and concurrent validity with various measures of functional impairment in major life activities (associated risks in executive functioning, educational history, occupational functioning, social relationships, marriage, driving, financial management, crime and drug use, parenting stress, and offspring psychopathology, among other domains).

More extensive technical information is provided in the manual.
