Conners' Rating Scales-Revised (CRS-R)
C. Keith Conners, Ph.D.

The revised Conners’ Rating Scales (CRS-R) are the result of 30 years of research on childhood and adolescent psychopathology and problem behavior. Revised language is simpler and clearer and additional items match the symptoms for ADHD outlined in the DSM-IV™.
 
Normative data for the revised forms comes from a large sample of children and adolescents throughout the U.S. and Canada. Norms are available for children and adolescents aged 3-17 on the parent and teacher rating forms; and for adolescents aged 12-17 on the self-report forms.
 
A number of new scales have been developed for the CRS-R. All three instruments (parent, teacher, and self-report) contain scales created through factor analyses to assess a broad range of significant problem behaviors. Each contains rationally created scales that correspond with symptoms used in the DSM-IV™ as criteria for ADHD; they also contain a new empirically created index for assessing children and adolescents at risk for a diagnosis of ADHD. The widely used Hyperactivity Index for parent or teacher ratings (renamed the Conners’ Global Index) is also included on the long version of the parent and teacher forms.
 
The CPRS-R includes a ColorPlot™ Profiles Form for proper age and gender profiling of scale scores. The ColorPlot™ Forms are ideal for presenting assessment results to parents.
 
Both long (CPRS-R:L) and short (CPRS-R:S) forms have been developed to assess problem behaviors reported by parents. Normative data for these revised scales comes from the ratings of more than 2,000 parents.

The CPR-S is a valuable tool for measuring treatment changes and for program evaluation. The scales are also extremely useful for routine screenings in schools, residential treatment centers, psychological, psychiatric and pediatric offices and clinics, juvenile detention facilities, child protective service agencies, and private practices.
