  1. Notes. Each row represents a separate multilevel model that adjusts for demographic/household covariates: school day (within-person; nightly measures only), boredom, loneliness, happiness, birth sex, race/ethnicity, household income, body mass index percentile, and depressive symptoms (all between-person). Models with predictors of interest other than sleep duration further adjust for sleep duration (linear and quadratic, sleep duration2). The within-person effect for nightly sleep measures is represented by the deviation from the adolescent’s overall mean at each time point. The between-person effect for nightly sleep measures is represented by each adolescent’s mean across all time points. The between-person effect for sleep variability measures is represented by SD, SRI, or social jetlag value per adolescent. Sleep timing measures (onset, midpoint, and offset) were centered around midnight (0:00). The mean number of valid actigraphy nights was 5.6 ± 1.4 (range: 3–9; IQR 5–7) and the mean number of breakfast reports was 5.5 ± 1.4 (range: 3–9; IQR 4–7) per adolescent
  2. aRanges from 0 (very bad)–3 (very good)
  3. bHigher value means greater variability, except the reverse for the SRI
  4. cCalculated based on formula from Phillips et al. [42]; ranges from 0 (low)–100 (high)
  5. dCalculated based on formula from Wittmann et al. [43]. N = 372 (adolescent included only if provided one weekday and one weekend night of actigraphy; n = 372)
  6. †p < .10, *p < .05, **p < .01, ***p < .001, two-tailed
  7. CI confidence interval, hrs hours, OR odds ratio, SRI sleep regularity index
