Assessment Reports
Assessment Reports are comprehensive and present scores for each scale numerically and graphically. Assessment Reports are available for all Conners CBRS components and can be accessed through the software and online versions. The Conners CBRS Assessment Reports include Feedback Handouts that present results from the parent, teacher, and self-report forms. These forms help the practitioner to summarize and describe the scores in broad, non-threatening, and easy-to-understand terms. Feedback Reports are ideal for parents and teachers as well as other relevant third parties. 

Progress Reports
Progress Reports compare the results of two to four administrations for the same individual to measure changes over time. These reports are ideal to use when monitoring treatment and intervention. Progress Reports are available for all Conners 3 components.

Comparative Reports
Comparative Reports compare the results of two to five administrations from different raters (e.g., mother, father, and a teacher) to establish the similarities and difference in reports of the youth’s functioning in different contexts.

About the Author

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.
