ARC’s Self-Determination Scale

The Conners’ Rating Scales– Third Edition (Conners-3; Conners, 2008) is an assessment for children ages 6 to 18 years; it is designed as a thorough assessment of ADHD and comorbid disorders such as Oppositional Defiant Disorder and Conduct Disorder. The components of the Conners-3 are available in paper-and-pencil or computerized formats.


Three versions are available: the Conners-3-Parent (Conners-3-P), the Conners-3-Teacher (Conners-3-T), and the Conners-3-Self-Report (Conners-3-SR), with both long and short forms. The CRS-3 includes the Conners-3 Global Index (Conners-3GI), a measure of general psychopathology. The CRS-3 includes the Conners-3 ADHD Index (Conners-3AI), a 10-item ADHD index. The Conners-3AI is intended to be used as a screener for ADHD. Both the Conners-3GI and the Conners-3AI are included as part of the full-length Conners-3 or may be purchased separately.
