Note. SE. = Standard Error; CSHQ = Children’s Sleep Habits Questionnaire; SSR = Sleep Self Report; Tx. = Treatment; IE = Independent Evaluator; results for covariates (gender, age, and number of school nights) are not reported in the table. Random effects, including variance of intercept and autoregressive model of order 1 (AR1) residual covariance parameters (to correct for autocorrelation between time points) were included in the model but are not reported in the table. Estimated marginal means and standard errors are reported to guide interpretation of direction of effects relative to baseline.
