This study sought to determine if perceived neighborhood danger impacted children's sleep. The current study asks: how does perceived neighborhood danger impact children’s sleep both quantity and quality (duration and efficiency), could children’s physical activity mediate these associations, and how do genetic and environmental factors play into these relationships? Questionnaires, biological measurements, and actigraphy watch data were collected from 709 8-year-old Arizonan twins and their parents in order to calculate neighborhood safety, sedentary physical activity, moderate to vigorous physical activity, sleep duration, and sleep efficiency as well as covariates. It was concluded that perceived neighborhood danger does not directly impact children’s sleep duration and efficiency, children’s physical activity does not mediate the relation of perceived neighborhood danger and children’s sleep, but rather, perceived neighborhood danger indirectly impacts children’s sleep duration and efficiency through moderate to vigorous activity, and finally, that both sedentary and moderate to vigorous activity are heavily influenced by genetics.

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.

Stress is common, and potentially adverse, for individuals transitioning to college. The purpose of the present study was to describe and understand first year college students’ experiences of stress. Specifically, the goals of this study were twofold: (1) to describe the types of stressors experienced by students transitioning into college and (2) to understand the predictors of students’ experiences of the different forms of stressors. Ecological Momentary Assessments were collected over the course of the first semester of the participants’ (N = 194, 56% female) first semester of college. Stressors were coded into 8 categories: academic, global interpersonal (family, peer, other interpersonal), obligational, health, and finances. It was found that (aim 1) academic stressors were endorsed the most frequently, followed by global interpersonal stressors and obligational stressors. Results also showed that (aim 2) males reported more frequent academic stressors than females, and females reported more frequent interpersonal stressors than males. In addition, higher GPA was positively related to obligational stressors and family support was positively correlated with academic stress. These findings suggest a need for increased awareness of stressors that students within differing contexts experience in a university setting.

College students are exposed to stress accumulating from daily challenges, personal relationships, financial struggles, and academic pressure. Stressors can challenge an individual to perform better or serve as a hindrance to academic achievement, depending on the individual’s perception of stressors and capacity to overcome them (Lepine et al., 2004). Optimal levels of stress are beneficial to managing responsibilities in a timely manner, while unmanageable levels of stress can negatively impact motivation and achievement. Higher levels of negatively perceived stress could have measurable consequences on academic outcomes, including lower motivation and lower achievement. This study focuses on examining the prospective relationship between levels of college stress and the academic outcomes, accounting for individual differences in vulnerability to stress. Specifically, I examined whether the associations between stress (T2) and academic outcomes (T3) were moderated by earlier (T1) levels of economic hardship and effortful control as risk and resilience factors, respectively. I predicted that higher levels of college stress would be associated with lower academic motivation and performance. I expected that higher effortful control would show a stronger association between higher academic motivation and achievement with lower college stress levels. I also predicted that higher levels of familial economic hardship would exacerbate the influence of college stress on lower academic motivation and achievement. This study utilized data collected from survey measures administered to students during the transition from high school to college. Results demonstrated a significant negative association between increased college stress and higher academic outcomes. A lack of significant interactions propose that economic hardship does not have negative effects on academic outcomes. The findings of this study will help universities to support students experiencing detrimental levels of stress to improve later academic outcomes.

The neighborhood context is an important predicator of developmental outcomes, as it is where children spend much of their time. Especially when it comes to urban, low-income areas, high neighbor danger and crime have been considered a developmental risk. Research has documented the links between neighborhood environments and academic achievement, but less is known regarding the holistic view that considers contexts in conjunction with the neighborhood, despite these being important levels of influence. Thus, this study examined: 1) the direct associations between parent report of neighborhood danger and objectively measured neighborhood crime and academic achievement (e.g., Woodcock-Johnson IV), 2) family level stress as a potential mediator in these links, and 3) the teacher-child relationship as a potential moderator of these associations. Participants were from the ethnically and socioeconomically diverse Arizona Twin Project study (N=707 twin children, Mage = 8.44 years; SD = 0.69; 28.0% Hispanic/Latino, 57.7% Non-Hispanic White, 3.4% Asian American, 3.8% African American, 2.6% Native American, and 2.8% multiethnic or other; 53.5% middle to upper class, 15.6% lower middle class, 21.6% living near the poverty line, and 7.4% living in poverty as calculated by an income to needs ratio). There were no direct effects between subjective neighborhood danger and indicators of academic achievement, but there was a positive association between objective crime and scores on applied problems (an indicator of math achievement). Family- level stress was a significant mediator of perceptions of neighborhood danger and scores on passage comprehension (an indicator of reading achievement) but did not play a mediating role in the relation between objective crime and academic achievement. Specifically, higher levels of danger and crime were associated with greater levels of family stress, and lower levels of academic achievement scores. The teacher-child relationship was not a moderator in the relation between neighborhood danger/crime and academic achievement. Study findings provide additional evidence regarding the differences in subjectively versus objectively obtained data on the neighborhood environment and can inform future intervention (e.g., in the home and at schools) that support student’s academic achievement by addressing multiple levels of contextual influence.

Many studies indicate a positive relationship between fundamentalism and sexual and racial prejudice. Many of these studies use the Religious Fundamentalism Scale (RFS), the Attitudes Towards Homosexuals Scale (ATHS) and the Manitoba Scale. However, there appears to be overlap between RFS and both ATHS and the Manitoba Scale, unaddressed by the literature. This study looked at possible overlaps between RFS and ATHS and between RFS and the Manitoba Scale that could inflate the correlation statistic of fundamentalism and sexual and racial prejudice. The Intratextual Fundamentalism Scale (IFS), a study without authoritarian or apparent prejudice-overlapping items, was also tested for overlap. Results showed two-factor structures—namely fundamentalism and prejudice—with only two items loading to the opposite factor. However, there were many near-zero item loadings. The discussion suggests ways to change these items to increase factor loadings and to change overall measures construct validity. The correlations between fundamentalism and sexual prejudice were not significant before modifying the measures and were small and negative after modifying (modifying measures means removing all crossloaded and near-zero loaded items). The modified fundamentalism and sexual prejudice measures correlations do not follow the literature. This may be due to the sample including sexual orientation minorities and a majority of atheist, agnostic, or ‘nothing in particular’ affiliations. The correlations between fundamentalism and racial prejudice were medium and positive before modifying and were small and positive after modifying. This falls in line with the literature of small and medium positive correlation statistics.

I studied how hostile and benevolent language influences one’s ability to change their misconceptions. Participants were less likely to revise their misconceptions when reading tweets with hostile language than those exposed to benevolent language, which stresses adopting a neutral or benevolent tone to increase the likelihood of successful revision. This may be due to a shift of memory resources from the less engaging Tweet information to the more engaging, evocative hostile language.

Social isolation in early childhood can have life-long effects on social behaviors and development. Cerebellar crus I has additionally been linked to social behaviors through forebrain pathways. In this study, we hypothesized that social isolation of mice from postnatal day 21 (P21) until p35 would result in impaired social behaviors. Additionally, we hypothesized that gq DREADD injections into crus I, to increase levels of cerebellar stimulation, at the start of the isolation period would counteract the effects of isolation, leading to mice who displayed normal social behaviors. Social behavior at P35 was tested using the 3-Chamber Task, a well-established model, and SLEAP deep-learning software was used to obtain quantifiable data. We found no difference in social behaviors between socially raised and isolated mice. However, gq DREADD mice displayed greater levels of social interaction and exploration than either socially raised mice or isolated mice. This research carries implications for possible therapeutic interventions for groups prone to social isolation, such as those with developmental disabilities, minority groups, the elderly, and prison populations.

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.

Early stages of the COVID-19 pandemic introduced a change in communication norms in regard to well-being. People traversed through different forms of communication to adapt to policies and regulations that limited in-person interactions to prevent the spread of the COVID-19 virus. Social interactions have been found to be an innate human need, important to one’s health and well-being. The study looked at the relationship between socializing and well-being during the state of the COVID-19 pandemic. Socializing variables consisted of remote and in-person socializing which in-person socializing was divided into two distinct categories. In-person socializing was divided into in-person safe socializing, indicating socializing that was safe from the risk of contracting the virus, and in-person unsafe socializing which indicates that socializing was at risk of contracting the virus. Additionally, the current study also investigated how age moderates this relationship between socializing and well-being. SEM analyses reported that in-person unsafe socializing has a significant positive association with well-being outcomes: anxiety and depression which indicate high levels of anxiety and depression with increased in-person unsafe socializing. The study also found remote socializing to have a significant positive association with the well-being outcome: positive affect, indicating increased levels of positive affect with increased remote socializing. Regression analyses looked at moderation by age, finding no significant interactions of age between socializing and well-being. Findings suggest the beneficial role of remote socializing and although remote socializing cannot replace in-person interactions, it serves as a supplemental resource during unpredictable events such as the COVID-19 pandemic.
