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.
The CAARS Computer Program enables online administration of the scales or, with the use of the QuikEntry mode, responses may be entered from a paper-and-pencil version into the computer program for fast and reliable scoring and report generation.
CAARS QuikScore forms are available in long, short, and screening 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, or just seconds with the computer program.
The long version of the 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.
