Product Description

When ADHD persists into adulthood, it usually contributes to larger personal and professional difficulties. The CAARS measures the presence and severity of ADHD symptoms to help determine whether or not ADHD is a contributing factor to an individual's problems.

Key Features

  • Multiple scales that assess ADHD and related symptoms and behaviours
  • Self-report and observer rating forms
  • ADHD Index which contains the items that best distinguish individuals with ADHD from non-clinical individuals
  • Scales that match DSM-IV criteria for ADHD
  • Inconsistency Index for identifying unusual response patterns
  • Parallel structure to CRS-R so that the two metrics together allow assessment across the life-span.

Areas measured by the CAARS

The CAARS quantifies ADHD symptoms across clinically significant domains and explores the manifestations of those symptoms. The key areas measured are:

  • Inattention/Memory Problems: people with high scores learn more slowly/have problems organising and completing tasks/have trouble concentrating.
  • Hyperactivity/Restlessness: high scorers have difficulty working at the same task for long/feel more restless and 'on the go' than others.
  • Impulsivity/Emotional Lability: high scores suggest tendency to engage in more impulsive acts than others/moods change quickly and are often/more easily angered and irritated by people.
  • Problems with Self-Concept: People with high scores have poor social relationships, low self esteem and low self-confidence.
  • ADHD Index: High scores suggest clinically significant levels of ADHD symptoms. High scores here are useful for differentiating clinical from non-clinical individuals.
  • DSM-IV Inattentive Symptoms: high scorers have tendencies associated with the inattentive sub-type of ADHD described in the DSM-IV.
  • DSM-IV Hyperactive/Impulsive: high scorers have tendencies associated with the hyperactive/impulsive sub-type of ADHD described in the DSM-IV.
  • DSM-IV Total ADHD Symptoms: high scorers meet the criteria for ADHD as described in the DSM-IV.

The CAARS consist of six complementary scales; three self-report scales (long version, short version and screening version) and three observer scales (long version, short version and screening version). The self-report (CAARS-S) and observer ratings (CAARS-O) both address the same behaviours and contain identical scales, sub-scales and indexes.

With the hand scored format, raw scores and T-scores are produced for each scale, sub-scale and index. These are then plotted on Profile Forms.

Long Versions

The long self-report (CAARS-S: L) and observer (CAARS-O:L) forms provide scores for all sub-scales, the ADHD index, and Inconsistency Index. The long versions provide the most detailed information upon which to base treatment plans.

Short Versions

The short self-report (CAARS-S: S) and observer (CAARS-O: S) forms examine and highlight key dimensions, making them ideal when time with a respondent is limited. The short versions are also often used during treatment to track progress over time. They include abbreviated versions of the factor-derived sub-scales that are in the long versions. The ADHD Index and the Inconsistency Index are included as well.

Screening Versions

The screening versions of the self-report (CAARS-S:SV) and observer (CAARS-O:SV) forms focus on DSM-IV criteria for quick ADHD identification. They include the DSM-IV ADHD sub-scales and the ADHD Index to screen for the possibility of ADHD.

Reliability

A number of statistical exercises were undertaken to determine the reliability of the CAARS scales with men and women in particular age groups. It was found that CAARS scales are quite accurate in measuring the constructs they were developed to assess.

Norms

The normative sample for self-report forms includes 1026 non-clinical adults. The normative sample for observer forms includes spouses, family members or friends of 943 non-clinical adults. Separate norms are available by gender and age group intervals.

Duration

Long versions: 30 minutes, short versions: 10 minutes.
