CGAS = Children’s Global Assessment Scale (reported for the anxious group only). SCARED-P = Screen for Child Anxiety Related Disorders, Parent Report. SCARED-C = Screen for Child Anxiety Related Disorders, Child Report. WEP = Wake Episodes. WASO = Wake After Sleep Onset. TST = Total Sleep Time. TST SD = Standard Deviation of Total Sleep Time (Intraindividual Variability in Sleep Duration). Sleep Onset SD = Standard Deviation of Sleep Onset. Sleep Offset SD = Standard Deviation of Sleep Offset. Co-Sleeping is coded as 1 = usually, 0 = rarely or sometimes. Race/ethnicity is dummy coded as 1 = white/Caucasian, 0 = other. Marital status is dummy coded as 1 = married, 0 = other. All CGAS correlations are presented for the anxious group only.
