| dc.description.abstract | Sleep studies have rarely explored individual differences in sleep disruption and associated outcomes at early ages. In two studies, this dissertation addresses both of these limitations using actigraphy, an activity-derived assessment of sleep, to increase understanding of negative impacts of sleep on early development. Study 1 investigated sleep disruption in foster children and sleep-related treatment outcomes of the Multidimensional Treatment Foster Care for Preschoolers (MTFC-P) intervention program. Study 2 explored individual differences in the associations among sleep, children's behavior, and neurohormonal activity. Four groups of participants ages 3- to 7-years-old were included in both studies: (1) Regular foster care (RFC; n=15); (2) MTFC-P intervention (TFC; n= 17); (3) Low-income community (LIC; n= 18); and 4. Middle-income community (MIC; n=29). Results of Study 1 indicated greater sleep disruption in foster groups, as evidenced by longer sleep latencies and increased variability of sleep duration, in the TFC group than in community groups. There was also indication of a treatment effect as the TFC group slept longer than RFC and LIC groups and had earlier bedtimes, fell asleep earlier, and spent more time in bed than either community group. LIC children had marginally more active sleep than MIC children, indicating a possible role for socioeconomic status in sleep quality. In Study 2, correlational and causal modeling approaches were used to investigate associations among sleep disruption, problem behaviors, and diurnal cortisol. Influences of foster care placement, gender, and age were also examined as potential individual difference factors. Results of mixed linear autoregressive models indicated that children were more likely to display inattentive/hyperactive behaviors after shortened sleep durations. Furthermore, at lower sleep durations, differences among care groups and genders emerged as children in foster care and males were at heightened risk for inattentive/hyperactive behavior problems. No associations between sleep and disruptive problem behaviors were found and there were few associations with morning and evening cortisol values. Results of these studies are discussed in terms of the effectiveness of the MTFC-P program for addressing sleep problems in foster children. Additionally, clinical implications of the heightened likelihood of inattentive/hyperactive behavior problems after disrupted sleep in some children are discussed. | en |
