Perceptual speed domain - Average of 4 tests

We formed a composite measure of the cognitive domain **perceptual speed** 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 4 cognitive tests are used to compute this score:

test score | z-score | cognitive test |
---|---|---|

cts_sdmt | z_SDMT | symbol digits modality test (oral) |

cts_nccrtd | z_NCcrtd | number comparison |

cts_stroop_cname | z_cname | stroop color naming |

cts_stroop_wread | z_wread | stroop word reading |

*Item level variables are available upon request.*

Note: The variable is calculated if more than half the z-scores are non-missing.
