Test for Dementia Over Time in Adults Age 56 to 105 Years
The DRS-2 assesses a patient’s overall level of cognitive functioning.
Features and benefits
- Used to track changes in cognitive status over time.
- Two forms allow for a better characterization of declining cognitive status and an improvement in the evaluation of treatment efficacy.
- Shorter test time if the client performs well early on in each subscale as subsequent tasks are credited with correct performance.
- The DRS-2 Interpretive Report is available on PARiConnect.
Alternate form facilitates retesting
The DRS-2: Alternate Form reduces the practice effects that can occur with repeated administrations of the DRS-2. The availability of two DRS-2 forms allows for a better characterization of declining cognitive status and an improvement in the evaluation of treatment efficacy.
- The item content and stimuli are structured to mirror those in the DRS-2.
- Reliability between the forms is strong, with a correlation coefficient of .82 for the Total Score and correlation coefficients ranging from .66 to .80 for the subscales.
- Several other studies, including a generalizability study and an equipercentile equating study, were conducted to determine the equivalency between the two forms.

FAQs
What is the technical information for the DRS-2™?
Technical information
- Age-corrected normative tables are provided for all DRS-2 subscales; age- and education-corrected normative data are provided for the DRS-2 Total Score.
- Validity studies comparing the DRS with WMS and WAIS-R subtests and the MMSE are presented.
Test structure
- Five subscales provide additional information on specific abilities: Attention, Initiation/Perseveration, Construction, Conceptualization, and Memory.
- Within each subscale, the most difficult tasks are presented first. If the first one or two tasks in a subscale are performed well, subsequent tasks in the subscale are credited with a correct performance and the examiner proceeds to the next subscale—a procedure that significantly shortens the total testing time.
- The 32 stimulus cards are contained in a separate binder.
