Description: The Connors Rating Scale - Revised (CRS-R) updates the original Conners’ Rating Scale, provides three scales rather than two, with long and short versions of each scale. The “Hyperactivity Index” had been renamed the Conners’ Global Index, and is included on the forms for teachers and parents. While the long versions require more time to complete, they correspond more closely to the criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV, APA, 1994).  The short version is useful when time is limited or when repeated administrations are needed.

Scoring: Computer programs are available for scoring, calculating standardized T-scores from raw scores, and providing graphic display and a report of the results.

Reliability: The coefficient alphas for internal reliability were highly satisfactory for the normative groups.  For the long form there was a range from .728 to .942 and .857 to .938 for the short form of the CRS-R, indicating that the CRS-R subscales are accurate in measuring the constructs they were intended to measure.

Validity: One The CRS-R has been compared to the CDI, The CRS, and the CPT overall index.  Correlations were also done between the teacher, parent, and adolescent ratings. The results indicate that the CRS-R does in fact identify childhood and adolescent ADHD behavioral problems and psychopathology. Validity studies are continuing.

Norms: The normative sample consisted of over 8000 cases.  Data are from over 200 schools in over 45 states and 10 provinces throughout the US and Canada for parents, teacher and self-reports was included.

Suggested use:  The main use of the CRS-R is for the assessment of ADHD.  The subscales however provide information useful for assessment of conduct problems, cognitive problems, family problems, emotional, anger control and anxiety problems. The CRS-R can be used for screening, for treatment monitoring, as a research instrument, and as a clinical diagnostic aid.
