The Conners' Adult ADHD Rating Scales (CAARS) fulfill the need for a reliable and valid measure of ADHD symptoms for use with adults. The CAARS provide a multimodal assessment of symptoms and behaviors associated with ADHD in adults aged 18 and older. The CAARS are a set of easily administered instruments consisting of self-reports and observer ratings allowing for the multimodal assessment of adult symptoms and behaviors. Normative data for the self-report forms consist of 1,026 non-clinical adults (ages 18-80), while normative data for the observer forms are based on spouses, family members or friends of 943 non-clinical adults (ages 18-80). The CAARS employs the easy-to-use MHS QuikScore format for administering, scoring, and profiling, and separate norms are available by gender and age-group intervals.
CAARS QuikScore forms are available in long and short versions. Scale descriptions and administration times for each version are described below. Scoring the CAARS will take about 10 minutes using the handscorable QuikScore form.
The long version of the self-report form (CAARS-S-L) and observer form (CAARS-O-L) have 66 items and contain 9 subscales. There are 4 factor-derived scales that assess a cross-section of ADHD-related symptoms and problem behaviors, 3 DSM-IV Symptoms measures (Inattentive Symptoms, Hyperactive-Impulsive Symptoms and Total ADHD Symptoms), and a 12-item ADHD Index that identifies respondents who might benefit from a more detailed clinical assessment. Takes about 15 minutes to administer.
The short versions of the self-report form (CAARS-S-S) and observer form (CAARS-O-S) contain 26 items and are abbreviated versions of the factor-derived subscales that appear on the long forms. As with the long version, the ADHD index and the Inconsistency Index are incorporated on these forms. The short versions require about 10 minutes to administer and were designed to be brief and to display key dimensions.
