  1. Lagged cross correlations between log of sleep efficiency ratios and log of mean maladaptive behaviors for 8 days before and 8 days after the target evening of sleep. Negative correlations indicate that poor sleep is related to problem behaviors and that the relation between these variables is chronic and not acute
