Dementia Rating Scale, Second Edition (DRS-2)
by Paul J. Jurica, Christopher L. Leitten, Steven Mattis
Overview
Measures mental status in adults with cognitive impairment.
Suitable for
Suitable for use with ages 55 to 89 years.
Product Description
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.
