CAARS Manual
When ADHD stays with a person into adulthood, it usually contributes to larger personal and professional difficulties. The Conners’ Adult ADHD Rating Scales (CAARS™) scales measure the presence and severity of ADHD symptoms so that you can determine whether or not ADHD is a contributing factor to a client’s difficulties.
Key Features
- Measures the presence and severity of ADHD symptoms
- Can be used in clinical, research, rehabilitation, and correctional settings
- Offers long, short, or screening versions
- Provides self-report and observer rating forms
The Conner’s Adult ADHD Rating Scales (CAARS) quantitatively measures ADHD symptoms across clinically significant domains while examining the manifestations of ADHD in adults based on scientific literature and the authors’ clinical experience. The CAARS results may help you identify contributing factors to a client’s problem in clinical, research, rehabilitation and correctional settings.
The CAARS elicit self-report and observer ratings to give a multiple-informant assessment. The self-report and observer forms address the same behaviours and contain identical scales, subscales, and indexes. Raw scores and T-scores are produced for each scale, subscale and index.
Normative data for the self-report forms consist of 1,026 nonclinical adults, while the observer forms consist of friends of 943 non-clinical adults. Separate norms are available by gender and age-group intervals (18-29, 30-39, 40-49, 50+ years).
