Standardized mean factor scores from invariant model over time, by racial group

Racial group	Year	Episodic memory	Semantic memory	Working memory	Perceptual speed	Visuospatial ability
White	BL	0^a	0^a	0^a	0^a	0^a
African American	BL	−0.043	−0.246	−0.477	−0.275	−0.870
White	1	0.068	−0.006	0.069	−0.006	−0.003
African American	1	0.156	−0.158	−0.441	−0.261	−0.825
White	2	0.059	−0.078	−0.009	−0.093	−0.050
African American	2	0.118	−0.198	−0.412	−0.193	−0.749

MEAN for standardized scores = 0; SD for standardized scores is 1. White baseline scores were arbitrarily selected to be the reference group and their mean at baseline was constrained to be ero.
