Description


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. Suitable for clinical, research, rehabilitation, and correctional settings, the CAARS scales quantitatively measure ADHD symptoms across clinically significant domains, while examining the manifestations of those symptoms.

The CAARS:SV include the same 12-item ADHD Index of the long and short CAARS forms and contain the DSM-IV™ ADHD Symptom Subscales (18 items that relate to DSM-IV™ criteria for ADHD). The Screening Versions are deal when insufficient time is available to complete the lengthier forms.

How to Use the Assessment
The CAARS provides a multiple-informant assessment with self-report (CAARS–S) and observer ratings (CAARS–O). Both address the same behaviors and contain identical scales, subscales, and indices. Long, short, and screening versions are available for each. With the handscored format, raw scores and T-scores are produced for each scale, subscale, and index, and are then plotted on Profile Forms. With software and online formats, Profile Reports and Interpretive Reports can be instantly generated.
