Note. All models include person-level random intercepts and time slopes (linear and quadratic).

^a0 = White, 1 = Other race;

^bAge centered at the sample mean (14.7);

^c0 = unmedicated day, 1 = medicated day;

^d0 = school day, 1 = non-school day;

^e0=girl, 1 = boy;

^fEMA time point across the day, centered at afternoon (after school) prompt.

^*p < .05.

^**p < .01.

^***p < .001.
