Description
The transition from high school to college is associated with considerable life strain for adolescents, including higher reported levels of daily stress and negative affect (NA), and alterations in stress physiology have been linked to poor health. The purpose of this thesis was to use an ecological momentary assessment design to study associations between momentary experiences of negative affect and cortisol levels in a sample of adolescents transitioning to college. I also examined the potential moderating effects of two potential vulnerability or protective factors, alone status and perceived social support from friends. Adolescents provided salivary samples and completed paper-and-pencil diary reports of socioemotional experiences and alone status five times per day for three consecutive weekdays, as well as completed self-report questionnaires on perceived social support from friends. Within-person increases in momentary negative affect were associated with momentary cortisol reactivity. Alone status significantly moderated this association such that the association between momentary negative affect and momentary cortisol levels was only significant when individuals were with others and not when they were alone. Perceived social support from friends did not significantly moderate the within-person associations between negative affect and momentary cortisol levels. The findings add to our understanding of physiological correlates of socioemotional experiences, as well as contexts in which these associations may be exaggerated or attenuated. The findings inform our understanding of potential pathways by which physiological reactivity to socioemotional experiences may affect the health of adolescents as well as how prevention efforts could reduce potential poor health outcomes associated with heightened stress reactivity.

Description
The objective of the current study was to examine sleep and academic functioning during middle childhood. More specifically, the twin design was used to determine the heritability of academic competence and sleep. Phenotypic analyses using multi-level mixed model regressions were performed to predict academic functioning from sleep. Lastly, socioeconomic status was tested as a moderator in the associations between sleep and academic functioning. Participants included twins (N = 191 families; Mage = 8.47 years) recruited from Arizona birth records at 12 months of age. Sleep duration, latency, onset, efficiency, variability, and sleep problems were assessed using actigraph watches and the Child Sleep Habits Questionnaire. Academic functioning was assessed using subtests of the Woodcock Johnson Cognitive Test of Achievement-IV (picture vocabulary, passage comprehension, and applied problems) and the MacArthur Health and Behavior Questionnaire. As determined by twin intraclass correlations, the heritability of academic competence ranged from 51-76%. Sleep heritability ranged from 14-80%. In addition, phenotypic analyses only showed a significant association between sleep latency and WJ picture vocabulary scores. More specifically, sleep latency was negatively associated with the picture vocabulary subtest. Additional models were run to examine if any interactive effects were present between early SES and the various sleep parameters. Several significant associations were observed with applied problems scores and parent-reported academic competence. Specifically, for children of low SES, a significant positive association was observed for sleep duration and WJ applied problems scores, as well as for sleep efficiency and WJ applied problems scores. No significant associations were observed for sleep efficiency and HBQ scores with children of any SES. Also, no significant relationships were observed with children of high SES for any of the academic measures.

Description
The purpose of the current study was to determine the genetic and environmental contributions to the development of prosocial behavior in children using a population of 356 twins at 8 years of age. The study also aimed to examine whether qualities of parenting (specifically authoritarian and authoritative parenting styles) were phenotypic predictors of prosocial behavior. Both parent-reports and objective ratings of global prosocial behavior were used. Results supported prosocial behavior as a genetically-influenced trait with heritability estimates of 44% and 68% for parent reported and observed prosocial behavior, respectively. Data also suggested prosocial behavior as an environmentally-influenced trait. As hypothesized, authoritative parenting was moderately correlated with parent-reported prosocial behavior and authoritarian parenting was found to be low-to-moderately negatively correlated with parent-reported prosocial behavior. Multi-variable regressions demonstrated that authoritative parenting was significantly predictive of increased parent-reported prosocial behavior but authoritarian parenting was not predictive of decreased parent reported prosocial behavior. However, observed prosocial behaviors were largely independent of both authoritative and authoritarian styles of parenting.

Description
This study examined the cross-sectional and longitudinal associations among diurnal cortisol rhythms and sleeping patterns in adolescents. 79 participants completed the study over three days during the spring semester of their senior year in high school, and 76 of these subjects participated again over three days during the fall semester of their freshman year in college. They completed daily saliva samples and diary entries, while wearing an actigraph to obtain objective measurements of sleep duration and efficiency. Cross-sectionally, longer sleep duration was associated with a lower cortisol awakening response, a smaller area under the cortisol curve, and a steeper cortisol slope. Longitudinally, there was no significant relationship between sleep duration and these cortisol parameters. Moreover, sleep efficiency was not associated with cortisol parameters cross-sectionally nor longitudinally. Results suggest associations between concurrent sleep duration and cortisol patterns, and may have significant impact on understanding adolescents' physiological response to stress.

Description
Executive functioning (EF) is the cognitive processing of goal-oriented actions that are predictive of important life functioning skills. Middle childhood is an important time for academic achievement and social development. Positive and negative parenting practices were examined in the prediction of several child executive functioning outcomes in middle childhood, this thesis further examined whether early life socioeconomic status moderated such associations. This sample consisted of 708 twins (32% monozygotic, 36% same-sex dizygotic, and 32% opposite-sex dizygotic) with ethnically and socioeconomically diverse backgrounds at two age points, 12 months old (M = 12.5 months, SD = 1.06) and 8 years old (M = 8.41, SD = .40).There was a significant negative main effect between negative parenting and CPT. Further, positive parenting interacted with SES to predict CPT and Digit Span Forward. A significant positive effect was identified between positive parenting and CPT in low SES families, but not high SES families. Interestingly, greater positive parenting was associated with lower Digit Span Forward in high SES families, but not low SES families. These findings suggest that while negative parenting was associated with worse EF across the entire sample, the relationship between positive parenting practices and executive functioning outcomes differed based on early life socioeconomic status. Future research should examine whether various domains of executive functioning may follow different developmental patterns.

Description
It is widely understood that qualities of the home environment greatly influence child health outcomes (Nancy, 1999; Simons et al., 2010). While there has been much research regarding the role of direct parenting behaviors, there remains little research regarding how other qualities of the parent, such as cultural values, may affect child physiological outcomes. Furthermore, research has also suggested that the way in which parenting and culture may be associated with child outcomes may differ based on race/ethnicity (Pinquart & Kauser, 2018). In this thesis, I examined the direct associations between parental cultural values (i.e., mainstream, traditional) and child diurnal cortisol outcomes as well as other qualities of parenting (parental warmth, authoritarianism) and child diurnal cortisol outcomes in Hispanic and White identifying primary caregivers. A moderating model was then used to investigate the racial/ethnic differences which may exist in these associations through mixed model regressions.
Participants were 475 twins and their primary caregivers (mean age=8.48; Primary caregivers: 64% White, 36% Hispanic; 53.8% middle class or above). I found no main effects between parental cultural values and child cortisol outcomes and no main effects between parenting behaviors and child cortisol outcomes. However, when exploring the moderating role of race/ethnicity, it was found that, as compared to children of White primary caregivers, children of Hispanic primary caregivers who had higher levels of parental authoritarianism had steeper PM slopes, indicating more adaptive cortisol outcomes. This suggests that the adaptiveness of certain parenting behaviors may differ across racial/ethnic groups such that what is considered to be “good parenting” may not translate across differing racial/ethnic groups. Ultimately, further research should be conducted in order to further explore the impact of race/ethnicity in the outcomes of our children.
