Description
This dissertation combines three first-author manuscripts that focused broadly on the study of adolescent sleep within a family context (Sasser et al., 2021; Sasser & Oshri, 2023; Sasser et al., 2023). First, Chapter 1 introduces the theoretical background and empirical research that grounded the research questions and hypotheses explored across the studies. The first study (Chapter 2) examined the influence of family connection on actigraphy-measured sleep among Latinx late adolescents and explored family dynamics and cultural values as potential moderators. The second study (Chapter 3) investigated daily and average concordance between parent and youth actigraphy-measured sleep and how this varied as a function of family context (e.g., parenting, family functioning). The third study (Chapter 4) examined concordance in actigraphy sleep among parent-youth and sibling dyads and explored how relations differed across zygosity type and sleeping arrangements. The dissertation concludes with an immersive discussion (Chapter 5) that summarizes the key differences, similarities, and takeaways across studies and highlights future directions and implications for developmental science, public policy, and clinical interventions. Collectively, this dissertation contributes to the understanding of youth and adolescent sleep within a family context by identifying proximal (e.g., daily interactions with parents/siblings) and broader family-level factors (e.g., dynamics, culture) that may help promote more healthful sleep among both adolescents and their family members.

Description
Various physical and psychological forms of development take place during the transition from childhood to adolescence, including the onset of puberty, delayed sleep-wake behavior patterns, and increases in internalizing symptomatology. Theory suggests that pubertal processes influence the onset of internalizing symptoms, and this association may differ between boys and girls. The contextual amplification hypothesis suggests that pubertal development interacts with contextual or dispositional factors to impact risk for psychopathology. Family stress and peer stress are two critical factors during early adolescence that have potential moderating effects on the association between pubertal development and internalizing symptoms. In line with the biopsychosocial framework, the current study examined various psychosocial (e.g., family stress, peer stress) and biological (e.g., sleep, genetics) factors that may have effects on the puberty-internalizing relation. Participants were a racially/ethnically and socioeconomically diverse sample of twins who were part of an ongoing longitudinal study (N=818 children; Arizona Twin Project; Lemery-Chalfant et al. 2019). The current study examined the association between puberty and internalizing symptoms, with stress (i.e., family, peer) as potential moderators, and sleep indicators (i.e., objective and self-reported sleep) as potential mediators. Behavior genetic analyses explored the moderated heritability of family stress on internalizing symptoms. Findings revealed that greater pubertal development predicted higher internalizing symptoms in boys, but not girls. For girls, peer stress interacted with pubertal development to predict internalizing symptoms, but simple slopes were not significant. Sleep indicators were not significant mediators between pubertal development and internalizing symptoms for boys or girls. Univariate twin models revealed environmental influences on internalizing symptoms, and both genetic and environmental influences on peer stress. Family stress did not significantly moderate the genetic and environmental influences of internalizing symptoms.
