Data collection and measures: Some data will be recorded daily throughout the study, including parent diary measures of child sleep and the main child misbehaviors (noncompliance, tantrums, aggression). Other data will be collected in 4 major assessments periods. The baseline assessment will occur at the end of the initial assessment with the family and prior to the first treatment session. The midpoint assessment will occur prior to the start of the discipline intervention, approximately six week after the start of treatment. This assessment period allows for evaluation of disruptive behavior and sleep following the sleep component and an introductory segment (Setting Up for Success), but prior to the initiation of the core disruptive behavior / parenting intervention. In other words, any improvements in disruptive behavior could be attributed largely to the sleep or mealtime addition rather than the core parenting intervention. The second midpoint assessment will occur following the core intervention, but prior to initiating the sleep/mealtime component not previously covered. This allows for the evaluation of the combined sleep and disruptive behavior interventions, as well as a comparison in treatment outcomes for those who received the sleep component and those who received the mealtime/control component. A final assessment will occur following the conclusion of treatment. Survey data will be collected using on-line forms created in REDCap, and completed on a tablet that will be loaned to the family.
