Based on the solid findings and key elements of its predecessor, the Conners’ Rating Scales–Revised (CRS–R™),
the Conners 3 offers a more thorough assessment of ADHD. The Conners 3 now addresses co-morbid disorders
such as oppositional defiant disorder and conduct disorder. Each parent, teacher, and self-report form is available
in full-length and short versions.
You will benefit from the following enhancements:
• A large representative normative sample based on the latest US census data.
• A refined focus on ADHD in school-age children with a new age range (6–18 for parent and teacher scales and
8–18 for self-report scales).
• Strengthened Diagnostic and Statistical Manual of Mental Disorders: Fourth Edition (DSM-IV-TR™) connections.
• Clear applications in education settings that help identify children with clinical symptoms.
• A manual that provides step-by-step guidance on how to use the tool in intervention planning and monitoring.
As with its predecessor, the new Conners 3 is a multi-informant assessment. Gathering information from parents,
teachers and youth provides a view of the child’s disorder and concerns from multiple perspectives.
Key Areas Measured:
• Learning Problems
• Executive Functioning (NEW)
• Peer Relations
• Family Relations
DSM-IV-TR Symptom Scales:
• ADHD Hyperactive/Impulsive
• ADHD Inattentive
• ADHD Combined
• Conduct Disorder (NEW)
• Oppositional Defiant Disorder (NEW)

Enhanced content alignment across parent, teacher, and self

User friendly language for assessment of DSM-IV-TR
Direct item linkage to more DSM-IV-TR symptomatic criteria, Conners 3 replaced CRS-R Anger
including two new scales for DSM-IV-TR symptoms of CD Control Problems scale on the
and ODD CASS
Assessment of executive functioning (parent and teacher
New validity scales: Positive Impression,
Negative Impression, Inconsistency Index
Screener items for Anxiety and Depression
Severe Conduct Critical items which, if endorsed, indicate
the need for immediate follow-up
Impairment items to aid in determining DSM-IV-TR
impairment criterion and educational eligibility
Inattention assessed independently from Learning Problems
(a change from the combined Cognitive
Problems/Inattention scale on the CRS-R)
In order to focus the Conner 3 on ADHD assessment, the
CRS-R scales related to emotional issues (i.e. Anxious/Shy,
Perfectionism, Psychosomatic) have been removed and are
now represented in the Conner Comprehensive Behaviour
The Conners CBRS is a comprehensive assessment of a wide
range of emotional, behavioural, social and academic issues
in school-aged youth, and was developed concurrently with
the Conners 3.
The Conners 3 Short forms are constructed in a different
fashion than were the CRS-R Short forms. The Conners 3
Short forms represent all of the Conners 3 Content scales
and two Validity scales. The CRS-R Short forms contained 3
scales and the ADHD index. Note that the Conners 3 Short
forms do not include the ADHD index
The 10-item Conners 3AI is a standalone form. The CRS-R
included the ADHD Index along with the DSM-IV ADHD
symptoms is a form called the Conners ADHD/DSM-IV Scale
