Partner effects: Cross-domain associations

Note. 1,599 couples at T1. Episodic memory (MEM) and depressive symptoms (DEP) were standardized to the T metric using the T1 AHEAD couple sample (N = 3,198) as the reference, Mean = 50, SD = 10. Unstandardized estimates and standard errors are presented. Estimates are residualized for age, education, and functional limitations of both partners.

Model fit statistics: χ² (df) = 544.2 (354); Comparative Fit Index, CFI = 0.981; and root mean square error of approximation, RMSEA = 0.018.
