Estimates of the relation of each facet to change in each cognitive outcome from separate mixed-effects regression models adjusted for age, sex, and education. Results show the effect of a 1-unit change in trait score on annual rate of cognitive change. P-values are based on the t-distribution with degrees of freedom equal to 2,623 for analyses of episodic memory, 2,600 for semantic memory, 2,679 for working memory, 2,573 for perceptual speed, and 2,557 for visuospatial ability.
