The Conners Adult ADHD Rating Scales 2nd Edition (CAARS™ 2) is a measure that provides improved accuracy, greater insight, and enhanced utility for assessing and managing Attention-Deficit/Hyperactivity Disorder (ADHD) in adults.
The Conners Adult ADHD Rating Scales (CAARS™; Conners, Erhardt, & Sparrow, 1999), first published more than 20 years ago, has played a crucial role in ADHD assessments in adults for over two decades.

Updated and Expanded Norms
New normative data were derived from a large sample selected to be representative of the North American population based on the 2018 U.S. census and the 2016 Canadian census proportions (balanced equally by age and stratified by gender, race/ethnicity, education level, and geographic region).
An ADHD Reference Sample has been added to allow examiners to compare an individual’s scores to those produced by others already diagnosed with ADHD.
Extended Upper Age Range
The oldest normative sample age group in the original CAARS was 50 years and older.
The CAARS 2 Normative Sample includes stratified samples for seven age groups, with an upward expansion to include 50–59, 60–69, and 70+ years to ensure precision when assessing older adults.
Increased Fairness and Inclusivity
Increased fairness and inclusivity with gender-inclusive language, culturally sensitive items, and items and scales that show no evidence of measurement bias with respect to gender, race/ethnicity, country of residence, or education level.
Multiple Reference Sample
Examiners can now select reference samples from the General Population or individuals with ADHD. Both reference samples include the option to compare against a Combined Gender group, a Gender Specific–Males group, and a Gender Specific–Females group. The report allows a convenient side-by-side comparison of rater scores with multiple groups.
Increased Alignment with Conners 4th Edition (Conners 4™)
The CAARS 2 and Conners 4 (a measure of symptoms of and impairments associated with ADHD, along with common co-occurring problems and disorders for youth aged 6 to 18 years) were designed to be aligned and comparable to one another to facilitate a lifespan approach to ADHD assessment and monitoring and to simplify the integration of information as adolescents transition into adulthood.
