CRS-R (Conners’ Rating Scales-Revised)

Author: C. Keith Conners, PhD

An instrument that uses observer ratings and self-report ratings to help assess attention deficit/hyperactivity disorder (ADHD) and evaluate problem behavior in children and adolescents.

Various CRS-R versions offer flexible administration options while also providing the ability to collect varying perspectives on a child’s behavior from parents, teachers, caregivers, and the child or adolescent.

There are three versions—parent, teacher and adolescent self-report—all of which also have a short and long form available. In addition, there are three screening tools that offer the option of administering a 12-item ADHD Index or the 18-item DSM-IV^® Symptom Checklist, or both. These instruments also offer versions for parents, teachers, and adolescents.

How to Use This Test

The CRS-R instruments are used for routine screenings in schools, mental health clinics, residential treatment centers, pediatric offices, juvenile detention facilities, child protective agencies, and outpatient settings. The test can help:

• Measure hyperactivity in children and adolescents through routine screening



• Provide a perspective of the child’s behavior from those who interact with the child on a daily basis



• Establish a base point prior to beginning therapy and monitor treatment effectiveness and changes over time



• Provide valuable structured and normed information to further support conclusions, diagnoses, and treatment decisions when the parent, teacher, and self-report scales are combined

Key Features

Based on the original Conners’ Rating Scales, the CRS-R has many advantages, including:

• A large normative database to help support the instrument’s reliability and validity


• Multidimensional scales that help assess ADHD and comorbid disorders with links to DSM-IV diagnostic categories



• Teacher, parent, and self-report scales in long and short formats



• Applicability to managed care situations through the quantification and measurement of a variety of behavior problems
