Background: Impulsivity is a strong, consistent risk factor for heavier drinking and internalizing symptoms. However, it is unclear whether certain facets of impulsivity (e.g., lack of premeditation and negative urgency) are differentially related to drinking quantity versus internalizing and whether drinking quantity and internalizing serve as mechanisms through which impulsive traits confer risk for negative alcohol consequences. Method: Data are from a longitudinal study of contextual influences on alcohol response in emerging adults (N = 448, Mage = 22.27, 43.5% female). Longitudinal path models in Mplus tested whether UPPS-P impulsivity facets at T1 were prospectively associated with drinking quantity and internalizing symptoms (T2), and whether T2 drinking and internalizing symptoms mediated effects of T1 impulsivity on T3 negative alcohol consequences. Separate models were tested for positive and negative urgency and sex and age were included as model covariates. Results: Consistent with study hypotheses, T1 lack of premeditation indirectly predicted T3 negative alcohol consequences through heavier T2 drinking, whereas T1 negative urgency indirectly predicted T3 negative alcohol consequences through higher T2 stress and depressive symptoms. Contrary to hypotheses, lack of perseverance was not related to drinking quantity and alcohol use was not prospectively related to alcohol consequences. Conclusions: The current study found that distinct impulsive traits were associated with drinking quantity and internalizing symptoms, both of which conferred risk for negative alcohol consequences. Findings underscore the importance of targeting drinking behavior as well as internalizing symptomology based on the presence of specific impulsive personality traits. Such personality-centered interventions have shown promise in prior research.

Sleep and weight health during childhood can be the essential building blocks that influence later physical and psychological health. Researchers note how neighborhood effects on health may be mediated or moderated by parenting or family-related factors. This dissertation expanded on the efforts through an examination of contextual predictors of children’s health using the Arizona Twin Project dataset (N = 933; 51.7% female; 56.5% White; 25.6% Latino). The family stress model (FSM), contextual relevance model (CRM), and the integrated model were used to test the relations between neighborhood and family factors on children sleep and weight health. Parent perceptions of neighborhood danger and childhood opportunities index were tested using multilevel- mediation, moderation, and moderated mediation models to address some of the limitations in previous reviews. The FSM was partially supported: parental stress and strain mediated the association between perceived neighborhood danger with sleep efficiency. However, the FSM was not fully supported as parental stress and disrupted parenting did not serially mediate the associations between neighborhood conditions and sleep efficiency. Moderation analyses revealed that negative parenting exacerbates associations between perceived neighborhood danger and sleep duration, demonstrating amplified disadvantages processes of the CRM. Negative parenting also moderated the associations between perceived neighborhood danger and sleep efficiency; the relationship was beyond what was noted in the CRM. Greater neighborhood opportunity was more strongly related to greater body fat percentage in families with higher positive parenting, as compared to families with lower positive parenting. Familism significantly moderated the association between neighborhood contexts and parental stress and strain within a subsample (Latino descent only). Last, the exploratory multilevel moderated mediation models suggested that most associations did not vary by the subgroups explored (i.e., positive parenting, familism cultural value). These results join a growing initiative to explore the science of ecological context, culture, and family interplay.

The transition from high school to college (TTC) is a critical period of change, the effects of which may be exacerbated for Latino students, who often face additional minority-specific stressors, such as ethnic/racial discrimination (ERD). Research has documented links between ERD and sleep outcomes in adolescents, but less is known regarding the longitudinal impacts of ERD experiences during unique risk periods (e.g., TTC). Further, despite the central role of family in Latino adolescents’ lives, less research has explored the protective role of family factors (e.g., familism, family support) in links between ERD and Latino students’ sleep health. Thus, this study examined: 1) longitudinal associations between peer- and adult-perpetrated ERD in high school and actigraphy-measured (e.g., duration, efficiency, midpoint) and subjective sleep (e.g., problems) during the first year of college among Latino adolescents, accounting for college ERD experiences, and 2) familism and family support as potential moderators of these associations. Participants were 209 Hispanic/Latino adolescents (Mage=18.10; 64.4% female; 84.7% Mexican descent; 67.9% first-generation students) assessed at two time points (i.e., last semester of high school and second semester of college). There were no longitudinal associations between high school ERD and college sleep. However, there were concurrent associations between ERD and sleep in college. Specifically, greater college peer- and adult-perpetrated ERD were associated with less duration and lower efficiency at the same time point. Further, more college adult-based ERD was additionally linked with greater sleep problems. There were no significant moderation findings; however, the interaction between high school adult-based ERD and family support predicting college sleep problems suggested that adolescents reporting low levels of adult ERD in conjunction with higher levels of family support had the fewest sleep problems. Study findings provide additional evidence that ERD from both adults and peers is associated with reduced sleep duration and quality among Latino college students and suggest that current cultural stressors may be particularly influential on sleep during major socio-contextual shifts. These findings can inform future programs (e.g., sleep interventions) that provide support for students experiencing race-based stressors, such as ERD, to promote Latino student health and well-being.

The transition to college is a time of increased opportunity and stress that spans across multiple domains (e.g., social life, academic workload, finances). Adolescents who encounter significant stress during the transition to college may be vulnerable to adverse outcomes, due to a “wear and tear” of physiological systems, including the hypothalamic-pituitary-adrenal (HPA) axis. Latino students may be particularly at-risk for heightened stress exposure, as minority youth often experience both minority-specific stressors and general life stress. Despite this, the majority of research on Latino students is limited to the examination of singular forms of stress, and little is known regarding the cumulative impact of multiple forms of stress on Latino students’ HPA axis functioning. The present study employed a “multi-risk model approach” to examine the additive, common, and cumulative effects of multiple types of stress (general, academic, social, financial, bicultural, discrimination) on HPA axis functioning in Latino college students (N = 209; 64.4% female; Mage = 18.95). Results from three-level growth curve models indicated that, in the additive model, no stressors were associated with the CAR, but general stress was associated with a flatter diurnal cortisol slope (DCS) and bicultural stress was linked with a steeper DCS. In the common model, the college stress latent factor was related to a reduced cortisol awakening response (CAR), but not the DCS. In the cumulative model, cumulative risk was linked with a lower CAR, but not the DCS. These findings highlight the physiological correlates of various stressors experienced by Latino college students.

Pediatric chronic pain is pervasive and associated with myriad adverse consequences, yet due consideration has not been given to the mental health disturbances that often present alongside chronic pain and the etiological mechanisms that potentially underlie both. The current study examined the etiology underlying chronic pain and internalizing symptomology in middle childhood, considering both independent and co-occurring symptom presentations. Phenotypic parent-offspring associations across chronic pain and internalizing symptomology were also examined. Lastly, nuclear twin family models were tested to determine the extent to which genetic and environmental factors underlie parent-offspring transmission. The sample comprised 795 children (399 families; Mage= 9.7 years; SD = 0.92) and their parents drawn from the Arizona Twin Project. Results indicated that chronic pain was highly heritable (78%), whereas internalizing symptomology was modestly heritable (32%) and further subject to moderate shared environmental influence (50%). Moreover, 9% of the variance in chronic pain was explained by additive genetic factors shared with internalizing symptomology. Maternal chronic pain and internalizing symptomology were positively associated with both child chronic pain and internalizing symptomology. The association between maternal chronic pain and child chronic pain was more pronounced for girls than boys, whereas the association between maternal internalizing symptomology and child internalizing symptomology was more pronounced for boys than girls. Paternal chronic pain was not significantly associated with child chronic pain but was unexpectedly associated with lower child internalizing symptomology. The negative association between paternal chronic pain and child internalizing symptomology was more pronounced for boys than girls. Paternal internalizing symptomology was not significantly associated with child chronic pain but was positively associated with child internalizing symptomology. Lastly, the best fitting reduced nuclear twin family models for both chronic pain and internalizing symptomology retained additive genetic, sibling-specific shared environmental, and nonshared environmental parameters, where parent-offspring transmission was solely explained by shared genetics and sibling-specific shared environmental factors further accounted for co-twin resemblance. Results provide novel insight into common liabilities underlying chronic pain and internalizing symptomology in middle childhood, parent-offspring associations across chronic pain and internalizing symptomology, and the etiological mechanisms that explain symptom aggregation across generations.

The COVID-19 pandemic has generated alarming increases in psychological distress and alcohol use behaviors and has caused the greatest increases in depression and anxiety symptoms among college students. Prior studies have examined the impact of COVID-19 broadly on mental health and alcohol use outcomes; however, few studies have examined these impacts in college students. Previous studies have examined individual factors that could moderate the relation between COVID-19 related stressors and mental health and alcohol use outcomes, but knowledge is lacking regarding the role of emotion regulation. The present study aimed to examine the role of emotion regulation in the relation between both COVID-19 stressful experiences and COVID-19 related worry and mental health and alcohol use outcomes, and to explore racial/ethnic differences in their associations. Four hierarchical multiple regression models were conducted to assess main effects of COVID-19 stressors and emotion regulation, as well as moderation of the effect of emotion regulation on depression symptoms, anxiety symptoms, alcohol consumption, and alcohol use disorder (AUD) symptoms during the past year. COVID-19 related worry was associated with greater symptoms of both mental health outcomes, whereas COVID-19 related stressful experiences were associated with both mental health outcomes, more alcohol consumption, and more AUD symptoms. Difficulties in emotion regulation had significant main effects on mental health outcomes and AUD symptoms, but not alcohol consumption. Hispanic/Latinx students reported higher experiences of both COVID-19 related stressors, but consumed less alcohol than did White/European students. This study provides further insight into the nature of COVID-19 related stressors and their subsequent impacts. Implications for prevention and intervention on college campuses are discussed.

Prior research suggests that African American adults are more likely than White adults to experience negative alcohol use outcomes such as alcohol use disorder (AUD) despite reporting lower rates of alcohol consumption. Research also shows that African Americans experience higher rates of depression, which can increase risk for alcohol consumption and AUD through drinking to cope. The current study examined the role of depressive symptoms and drinking to cope in alcohol consumption and AUD symptoms among White and Black/African American college students. Participants completed an online survey during the fall (T1) and spring semester (T2) of their first year of college (N = 2,168, 62.8% female, 75.8% White). Path analyses were conducted to examine whether depressive symptoms and drinking to cope mediated the association between race/ethnicity and alcohol consumption and AUD symptoms, as well as whether race/ethnicity moderated the associations between depressive symptoms, drinking to cope, and alcohol use outcomes. Results indicated that White participants had higher levels of depressive symptoms and alcohol consumption than African American participants. Drinking to cope at T1 was also associated with more depressive symptoms at T1, higher levels of alcohol consumption at T2, and higher levels of AUD symptoms at T2. Also, there was an indirect effect of depressive symptoms on AUD symptoms via drinking to cope. Results from multigroup path analyses suggested that depressive symptoms were more strongly associated with drinking to cope for White students than African American students. There were no significant racial/ethnic differences in the associations between depressive symptoms or drinking to cope and alcohol use outcomes. Future research should examine the roles of race, depression, and drinking to cope in alcohol use outcomes for college students.

Parental Cultural Values, Qualities of Parenting, and Diurnal Cortisol Patterns in Middle Childhood: Differences in White and Hispanic Families?

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.
