The Conners 3 is used for assessing ADHD and comorbid disorders in children and adolescents.
The Conners 3 has been updated to provide a scoring option for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) Symptom Scales - click here for more information.
Individuals aged 6 to 18 years
Based on the solid findings and key elements of its predecessor, the Conners Rating Scales-Revised (CRS-R), the Conners 3rd Edition (Conners 3) offers a more thorough assessment of ADHD. The Conners 3 now addresses comorbid disorders such as Oppositional Defiant Disorder and Conduct Disorder. Each Parent, Teacher, and Self-Report Form is available in long and short versions. Long versions are available on this page as they were updated to reflected DSM-V scoring (the short forms were unaffected by the update).
As with its predecessor, the Conners 3 is a multi-informant assessment. It has a high level of consistency in the scales across raters, allowing for easy interpretation of multi-informant assessments. Users can examine critically any discrepancies between the informants, highlight certain behaviours and easily compare results.
The Conners 3 includes two popular indexes: the Conners 3 ADHD Index (Conners 3AI) and the Conners 3 Global Index (Conners 3GI). The Conners 3AI items were taken from the Conners 3 long form and efficiently differentiate between youth with ADHD and youth without a clinical diagnosis. This brief index is ideal for users who need to screen quickly for ADHD, and works well for screening large groups of children and adolescents to see if further assessment of ADHD is warranted. The Conners 3GI is a fast and effective measure of general psychopathology. It includes the 10 best-predictive items from the CRS-R parent and teacher rating scales. The items have remained unchanged; however, the normative data has been updated.
The Conners 3 also gives clinicians the choice of using a short form. Consisting of 43 items on the Parent Form, 39 items on the Teacher Form, and 39 items on the Self-Report Form, the short form is an excellent tool for screening large groups of students who may require additional assessment. The short form includes the strongest items from the long form's empirical scales and includes Positive and Negative Impression Indexes for all informants. This form is beneficial when an assessment is repeated a number of times and/or when administration time is limited. It also is useful for monitoring the success of treatment programmes over long periods.
The QuikScore forms convert raw scores to T-scores, providing the user with a clear and easily understood profile of results, and are available for all Conners 3 forms.
Important refinements have been made to the Conners 3 including: (1) Updated Validity scale guidelines with new language to better reflect the intent of the scales; (2) Refined T-score cutoff categories and category descriptions; and (3) The Aggression scale name change to Defiance/Aggression.
