FIGURE 4.

Predicted changes in executive function scores from baseline to wave 3 by baseline sleep quality score in the Kaiser Healthy Aging and Diverse Life Experiences Study (N = 1690), by race and ethnicity. Notes: Analyses were stratified by race and ethnicity. The executive function scores were z scored to the baseline sample. Linear mixed effect models were adjusted for baseline age, sex, race, interview mode, income, education, interactions between time and sleep, and interactions between time and all covariates except for interview mode. All models used time since baseline as the time scale and accounted for practice effects and interview mode (phone vs. in person). All models included random intercepts and random slopes
