Semantic memory domain - Average of 3 tests
Semantic Memory Domain
We formed a composite measure of the cognitive domain semantic memory by converting raw scores on each cognitive test to z scores, using the mean and standard deviation of the cohort, and then averaging the z scores to yield the composite.
The following 3 cognitive tests are used to compute this score:
| test score | z-score | cognitive test |
|---|---|---|
| cts_bname | z_BName | Boston naming (15 items) |
| cts_catflu | z_CatFlu | category fluency (animals - fruits/vegetables) |
| cts_read_nart* | z_read_nart* | reading test - (10 items) |
*For the MARS study, the NART reading test is replaced with the 15-item WRAT reading test
Item level variables are available upon request.
Note: The variable is calculated if more than half the z-scores are non-missing.
