Dementia Rating Scale, Second Edition (DRS-2)
Overview
Measuring mental status in adults with cognitive impairment.
Suitable for
55 to 89 years.
Product Description
Research conducted after the publication of the original Dementia Rating Scale (DRS) showed that both age and education contribute significantly to DRS sub-scale and total scores. This finding, along with several other factors provided the impetus for the development of the DRS-2.
The DRS-2 measures cognitive function at lower ability levels where some other evaluation instruments are limited by floor effects. The DRS-2 also can be used to track changes in cognitive status over time. By design, the DRS-2 measures deficits in a large range of higher cortical functions and differentiates deficits of varying severity levels.
The DRS-2 incorporates the original 36 DRS tasks and 32 stimuli, yielding five sub-scale scores, and an assessment of the patient's overall level of cognitive functioning. The five DRS-2 sub-scales provide additional information on specific abilities including Attention (8 items), Initiation/Perseveration (11 items), Construction (6 items), Conceptualization (6 items) and Memory (5 items). Stimulus items consist of material familiar to most individuals.
The DRS-2 tasks are presented in a fixed order. Within each sub-scale the most difficult tasks are presented first. Generally, if the first one or two tasks in a sub-scale are performed well, subsequent tasks in the sub-scale are credited with a correct performance and the examiner proceeds to the next sub-scale. This procedure significantly shortens the total testing time for individuals with relatively intact cognitive functioning.
Interpretive software available
The DRS-2:IR provides unlimited scoring and report generation after hand-entry of DRS-2 and DRS-2: Alternate Form responses.
- The software automatically generates age-corrected subscale scores, an age- and education-corrected DRS-2 Total Score, and percentile subscale scores.
- The Interpretive Report describes the client’s overall performance and subtest performance.
- A graphic profile of the client’s current performance (and up to three previous administrations) can be generated.
- Saves valuable time and provides useful documentation to assist in rehabilitative and therapeutic planning.
Qualification level required:

Norms
Age-corrective normative tables available for all DRS-2 sub-scales with age and education-corrected normative data for the DRS-2 Total Score.
