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.
