Note. 845 days nested within 132 individuals who participated during the school year. Sleep onset latency = time to fall asleep (natural log of minutes); Sleep midpoint = median of sleep start and sleep end time (0.00 = midnight, 3.00 = 3:00 AM, etc.); Sleep duration = time asleep (in hours); Level 1 bicultural stress centered within-person; continuous level 3 predictors grand-mean centered; Male: 1 = Male, 0 = Female; Weekend: 1 = Friday or Saturday night, 0 = all other nights; Est. = partial regression coefficient estimate (unstandardized); SE = robust standard error.
