History

The Conners Comprehensive Behavior Rating Scales (CBRS) were developed by C. Keith Conners to assess behavioral problems in children and adolescents. The Conners' Teacher Rating Scale, a 39-item symptom and behavior checklist designed for teachers in psychopharmacological studies, was introduced in 1969. Factor analysis of this scale identified five stable dimensions of teacher-reported symptoms, demonstrating its utility for assessing children with hyperkinetic disorders and evaluating the effects of pharmacological treatment. The Conners' Parent Rating Scale (CPRS) was introduced in 1970 to gather parental reports on behavioral issues in children referred for psychiatric evaluation. The initial CPRS comprised 73 items, formulated from parental observations and reports. In 1973, the CPRS-93 expanded this to a 93-item questionnaire intended to identify hyperkinetic children, assess problem behaviors, and evaluate drug treatment effectiveness across 25 areas. A revised 48-item version, the CPRS-48, was introduced in 1978. This streamlined version incorporated rewording, factor analysis for consistency, and included a Hyperactivity Index (HI) sensitive to treatment effects. Further updates in 1997 led to the development of the CPRS-R:L (80-item long version) and CPRS-R:S (27-item short version). These later revisions sought to address limitations such as small normative samples and outdated content, while also incorporating an ADHD Index and

-aligned items. These changes were based on data from a larger, more diverse normative sample of over 2,400 children.


Measurement

The CBRS was created to evaluate possible behavioural markers in children from ages to 6–18 comprehensively. These include: *

The CBRS has about 18 to 90 questions about the incidence of behaviours shown by the child. These questions are supplied by the

. Possible ADHD symptoms of the child can be determined along with the significance of each. This is done by asking questions about the child's home life, giving psychologists a better understanding of the child's normal behavioural patterns and habits. An analysis of the answers to the questions will help psychologists make a more accurate diagnosis of ADHD.


Versions


Short and long versions

There are two versions of the CBRS, the short and the long version. They are both used for different purposes by behavioural

There are three Conners CBRS forms, each form contains different questions for the specific person filling the form out.

Results analysis

The results are calculated by the psychologist who totals all the areas of the assessments completed by the child, parent, and, in some cases, teacher. These scores are

ranks. When the T-scores are less than 60, a respondent's test performance is in the normal range. However, when an average T-score is above 60, there is a possibility of behavioural issues. There are different categories: * T-scores above 60 indicate there may be an issue regarding ADHD. * T-scores from 61 to 70 indicate issues are lightly unusual, or moderately severe. * T-scores above 70 indicate issues are very unusual, or more severe. The higher a respondent's score, the higher their clinical likelihood of ADHD.
