Over 7,000 assessments were collected in the development of the Conners CBRS and Conners CI, including ratings of youth in the normative sample, clinical cases, and those included in the validity studies. In the normative study, 3,400 Conners CBRS assessments were collected. The normative sample is also diverse in terms of parental education level and geographic region.The large normative data sample is representative of the general U.S. population in terms of ethnicity/race, gender, and parent education level (U.S. Bureau of the Census, 2000
Separate norms are provided for males and females, in 1-year age intervals. Combined gender norms also are available. Back to the topReliability
Both internal consistency and test-retest reliability are very good for the Conners CBRS and the Conners CI. Internal consistency coefficients (Cronbach’s alpha) range from .69 to .97, and 2- to 4-week test-retest reliability coefficients range from .56 to .96 (all correlations significant, p < .001). Inter-rater reliability coefficients range from .50 to .89 (all correlations significant, p < .001). Validity
Support for the validity of the structure of the Conners CBRS was obtained using factor analytic techniques on derivation and confirmatory samples. Convergent and divergent validity were supported by examining the relationship between Conners CBRS scores and other related measures. Overall, scales that assess similar constructs tended to be moderately to strongly intercorrelated, while scales that did not assess similar constructs tended to have smaller correlations.
Results from discriminative validity analyses indicated that the Conners CBRS scores accurately discriminate between relevant groups. Results from a series of multivariate analysis of covariance revealed that, for all scales, the means for the target clinical groups were significantly higher than the means for the general population and other clinical groups. In terms of the classification accuracy of the scores (as determined by a series of discriminant function analyses), the mean overall correct classification rate was 78% across all forms. Back to the top Assessment Reports
Assessment Reports are comprehensive and present scores for each scale numerically and graphically. Scores are also reported in relation to the DSM-IV-TR diagnostic criteria and to special education eligibility categories as outlined in the IDEA 2004. In addition, the report includes a detailed description of each scale. Feedback Handouts are included in Assessment Reports, and these present results from the Conners CBRS parent, teacher and self-report forms. These handouts help the practitioner to summarize and describe the scores to parent, teachers and other relevant third parties in broad, non-threatening, and easy-to-understand terms. Feedback Handouts are ideal for parents and teachers as well as other relevant third parties. To download a CBRS Assessment Sample Report click here. 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 for monitoring treatment and intervention. 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. To download a CBRS Comparative Sample Report click here

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.
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
