Conners’ Adult ADHD Rating Scales

C. Keith Conners, Ph.D.
Drew Erhardt, Ph.D.
Elizabeth Sparrow, Ph.D.

Technical Information

Normative data for the self-report forms consist of 1,026 nonclinical adults, while the normative data for the observer forms consist of ratings by spouses, family members, or friends of 943 nonclinical adults. Separate norms are available by gender and age-group intervals (18–29, 30–39, 40–49, and 50+ years). 

Overall, the coefficients were highly satisfactory across the various normative groups. It was found that the CAARS measures (both self-report and observer) are quite accurate in measuring the constructs they were developed to measure.

Numerous validity studies were conducted on this test. The results of these studies supported the following hypotheses regarding factorial, discriminant, and convergent validity. The studies supported the following hypotheses:

  • The scale structure of the CAARS is appropriate and makes sense both empirically and theoretically.
  • The CAARS discriminates between relevant groups.
  • The CAARS correlates with the measures believed to measure related constructs.

Interpretive Reports
Interpretive Reports contain detailed descriptions of the scales, a list of elevated responses, and intervention strategy suggestions in addition to scores. They are available for the long and short versions of the CAARS

About the Authors 

C. Keith Conners, Ph.D.
Dr. C. Keith Conners has had an extraordinary and diverse career as an academic, clinician, researcher, lecturer, author, editor-in-chief, and administrator. His dedication to the study of ADHD and other childhood problems propelled him to the forefront of his field. His intense interest has led him to write several books, journal articles, and book chapters based on his research on ADHD and childhood disorders. He is highly recognized in the field of psychology for his numerous contributions.

In the course of his career, Dr. Conners was greatly intrigued by children exhibiting a diverse pattern of symptoms. He collected data on children from the general population and children with an existing symptom list who were referred to clinics, and eventually published the first version of the Conners’ Parent Rating Scale. The increasing use and popularity of the rating scales eventually made his original articles among the most cited in the literature on the subject.

Dr. Conners is now retired and is currently residing in North Carolina. He continues to lecture, present workshops on diagnosis and assessment, and serve as a consultant to numerous government and private organizations.

Dr. Conners was the recent recipient of the lifetime achievement award from both the Association for Children and Adults with Attention-Deficit and Hyperactivity Disorder (CHADD) and the Mental Health Research Association (NARSAD).

The Conners 3rd Edition™ (Conners 3™) and the Conners Comprehensive Behavior Rating Scales™ (Conners CBRS™) represent Dr. Conners’ life-long commitment to integrating the latest in academic research with contemporary clinical practice. Back to the top
