Within-person reciprocal links between stress, sleep, and depressive symptoms across Latino/a adolescents' transition to and through college.

Evidence suggests bidirectional relations between stress, sleep, and depressive symptoms in adolescence and young adulthood. Less research has disaggregated within- and between-person variance in these associations over time or within Latino/a college students. This study examined longitudinal, within-person reciprocal relations between stress, sleep, and depressive symptoms among 181 Latino/a adolescents (M age = 18.10; SD = 0.41, 35% male) transitioning to college. Participants were assessed in their senior year of high school and annually until their fourth year of college. A random intercept cross-lagged panel model (RI-CLPM) was used to parse out within- and between-person sources of variance. Results indicated overall (between-person) relations among depressive symptoms and school/college stress and sleep problems. There were reciprocal within-person links between stress and sleep problems across the first two years of college. Within-person increases in depressive symptoms during the second year of college predicted more stress than usual in the third year, which predicted increased depressive symptoms in the fourth year. More sleep problems than usual in the third year of college predicted higher stress in the fourth year. Findings provide evidence for within-person cross-lagged relations among various domains of adjustment during college and may inform future prevention efforts for incoming Latino/a college students targeting mental health and sleep problems.

Unique and interactive effects of threat and deprivation on latent trait cortisol among emerging adults.

Though considerable work supports the Dimensional Model of Adversity and Psychopathology, prior research has not tested whether the dimensions-threat (e.g., abuse) and deprivation (e.g., neglect)-are uniquely related to salivary trait indicators of hypothalamic pituitary adrenal (HPA) axis activity. We examined the unique and interactive effects of threat and deprivation on latent trait cortisol (LTC)-and whether these effects were modified by co-occurring adversities. Emerging adults (n = 90; Mage = 19.36 years; 99.88% cisgender women) provided salivary cortisol samples four times a day (waking, 30 min and 45 min postwaking, bedtime) over three 3-day measurement waves over 13 weeks. Contextual life stress interviews assessed early adversity. Though the effects varied according to the conceptualization of early adversity, overall, threat-but not deprivation, nor other co-occurring adversities-was uniquely associated with the across-wave LTC. Specifically, the incidence and frequency of threat were each negatively related to the across-wave LTC. Threat severity was also associated with the across-wave LTC, but only among those with no deprivation. Finally, the effects of threat were modified by other co-occurring adversities. Findings suggest that threat has unique implications for individual differences in HPA axis activity among emerging adults, and that co-occurring adversities modify such effects.

The Influence of Pubertal Development on Early Adolescent Sleep and Changes in Family Functioning.

Pubertal development has been separately linked to adolescents' sleep problems and larger family functioning, but research connecting these inter-related processes remains sparse. This study aimed to examine how pubertal status and tempo were related to early adolescents' sleep and their family functioning. Using longitudinal data from the Adolescent Brain and Cognitive Development study, the study's sample (N = 4682) was 49.2% female, was an average of 9.94 years old at baseline, and was 60.1% white. Analyses in the current study modeled the indirect associations between pubertal change and changes in family conflict via adolescent sleep duration and variability of duration. The results suggested that pubertal status and tempo predicted shorter adolescent sleep durations and greater variability in those durations, which predicted residual increases in family conflict. The findings highlight the role of adolescents' pubertal changes in their sleep and how such changes can negatively affect family functioning.

Stress and diurnal cortisol among Latino/a college students: A multi-risk model approach.

The transition to college is a time of increased opportunity and stress spanning multiple domains. Adolescents who encounter significant stress during this transition may be vulnerable to adverse outcomes due to a "wear and tear" of the hypothalamic pituitary adrenal (HPA) axis. Latino/a students may be particularly at-risk for heightened stress exposure due to experiences of both minority-specific and general life stress. Despite this, little is known regarding the cumulative impact of multiple stressors on Latino/a students' HPA axis functioning. The present study employed a "multi-risk model" approach to examine additive, common, and cumulative effects of multiple stress forms (general, academic, social, financial, bicultural, ethnic/racial discrimination) on diurnal cortisol in a sample of first-year Latino/a college students (N = 196; 64.4% female; Mage = 18.95). Results indicated that no stress forms were additively associated with the cortisol awakening response (CAR), but general stress was associated with a flatter diurnal cortisol slope (DCS) and bicultural stress was linked with a steeper DCS. A college stress latent factor was associated with a lower CAR, whereas a latent factor of discrimination was not associated with diurnal cortisol. Cumulative risk was linked with a lower CAR. Findings highlight the physiological correlates of various stressors experienced by Latino/a college students.

Ethnic-Racial Identity Developmental Trajectories Across the Transition to College.

There is limited longitudinal research examining multiple ethnic-racial identity (ERI) components from adolescence into young adulthood. The current study modeled Latino adolescents' ERI trajectories across the college transition (N = 206; Mage = 18.10 years, SD = 0.41; 65.0% female). Longitudinal data from a survey administered on five occasions across 3 years were analyzed using multilevel growth modeling. Prior to college, Latino heritage culture orientation was positively associated with ERI exploration and resolution. ERI exploration increased over time. ERI resolution was high with no average change; Latino heritage culture orientation predicted variability in resolution over time. Before college, male-identifying youth reported higher ERI public regard from teachers/professors compared to female-identifying youth. Public regard increased to a greater extent for female compared to male adolescents. The findings join evidence for lifespan and intersectional models of ERI development.

Bicultural competence and academic adjustment across Latino youth adaptation from high school to college.

This study investigated the association between bicultural competence and academic adjustment (i.e., engagement, efficacy, achievement) among 193 Latino youth (65.3% female; 89.1% U.S.-born) followed from their senior high school year (Mage  = 17.58 years, SD = 0.53) to their fifth college semester (2016-2019). Latent growth analyses revealed that youth's overall bicultural competence trajectory was moderately high and stable across this period. Youth who maintained or increased bicultural competence levels over time (slopes) demonstrated greater self-efficacy. Youth with greater high school bicultural competence (intercepts) demonstrated higher engagement but lower achievement. No other associations emerged. This study highlights that the promoting influence of bicultural competence may not extend to all indicators of academic adjustment but may depend upon the contexts and demands they navigate.

Reciprocal associations of perceived discrimination, internalizing symptoms, and academic achievement in Latino students across the college transition.

OBJECTIVE: Despite growing evidence that perceived discrimination negatively impacts underrepresented ethnic-racial college students, there is a lack of longitudinal studies with multiple sources of discrimination as Latinos transition from high school (HS) to college. This study examined changes in peer, adult, and everyday discrimination across the college transition and tested concurrent, prospective, and reciprocal associations between these sources of discrimination, internalizing symptoms, and grade point average (GPA). METHOD: Latino adolescents (N = 209; Mage at Time 1 = 18.10; 64.4% female; 85.1% Mexican descent) reported on discrimination experiences and internalizing symptoms during their final year of high school and first college semester. Participants' GPA was obtained from institutional records. Longitudinal data were analyzed using cross-lagged panel models. RESULTS: Adult discrimination remained stable while peer and everyday discrimination decreased from high school to college. All sources of discrimination were concurrently associated with internalizing symptoms, but not GPA, in high school and college. There were positive bidirectional associations between everyday discrimination and internalizing symptoms across the college transition. Adult discrimination during high school predicted increased discrimination from adults and peers in college. First-generation college students reported higher everyday and peer discrimination in college. CONCLUSIONS: Latino students' experiences of everyday and ethnic-racial discrimination in school may be more closely tied to psychological rather than academic adjustment in the first semester of college. First-generation college students and those who experienced higher adult discrimination or internalizing symptoms in high school appear to be more susceptible to increased perceptions of discrimination during the college transition.

Early Life Socioeconomic Differences in Associations between Childhood Sleep and Academic Performance.

Poor sleep can negatively impact children's academic performance. However, it is unknown whether early-life socioeconomic status (SES) moderates later sleep and academics. We tested associations between actigraphy-based sleep duration and midpoint time, and parent-reported sleep problems with objective and subjective measures of academic performance. We also examined whether relations varied by early and concurrent SES. Children (n=707; 52% female; M age=8.44 years; 28.7% Hispanic/Latinx; 29.7% at/below poverty line) were assessed at 12 months for SES and eight years for SES, sleep, and academics. There were no main effects of sleep on academics. More sleep problems predicted lower Applied Problems performance for low SES children (b=-.73, p<.05) and better performance for high SES children (b=.69, p<.05). For high SES children, greater sleep problems (b=-.11, p<.05) and longer sleep duration (b=-.11, p<.05) predicted lower academic achievement. However, most associations were consistent across SES, illustrating the complex interplay between sleep, academic outcomes, and SES.

Harsh Parenting Predicts Novel HPA Receptor Gene Methylation and NR3C1 Methylation Predicts Cortisol Daily Slope in Middle Childhood.

Adverse experiences in childhood are associated with altered hypothalamic-pituitary-adrenal (HPA) axis function and negative health outcomes throughout life. It is now commonly accepted that abuse and neglect can alter epigenetic regulation of HPA genes. Accumulated evidence suggests harsh parenting practices such as spanking are also strong predictors of negative health outcomes. We predicted harsh parenting at 2.5 years old would predict HPA gene DNA methylation similarly to abuse and neglect, and cortisol output at 8.5 years old. Saliva samples were collected three times a day across 3 days to estimate cortisol diurnal slopes. Methylation was quantified using the Illumina Infinium MethylationEPIC array BeadChip (850 K) with DNA collected from buccal cells. We used principal components analysis to compute a summary statistic for CpG sites across candidate genes. The first and second components were used as outcome variables in mixed linear regression analyses with harsh parenting as a predictor variable. We found harsh parenting significantly predicted methylation of several HPA axis genes, including novel gene associations with AVPRB1, CRHR1, CRHR2, and MC2R (FDR corrected p < 0.05). Further, we found NR3C1 methylation predicted a steeper diurnal cortisol slope. Our results extend the current literature by demonstrating harsh parenting may influence DNA methylation similarly to more extreme early life experiences such as abuse and neglect. Further, we show NR3C1 methylation is associated with diurnal HPA function. Elucidating the molecular consequences of harsh parenting on health can inform best parenting practices and provide potential treatment targets for common complex disorders.

Negative affect reactivity to stress and internalizing symptoms over the transition to college for Latinx adolescents: Buffering role of family support.

Affect reactivity to stress may play a role in the development of internalizing symptoms during the college transition, a critical developmental juncture for Latinx adolescents, the largest ethnic minority group on college campuses. This study examined whether affect reactivity during high school is associated with internalizing symptoms in college and explored two potential protective factors, perceived family and peer support. Participants were 209 Latinx adolescents (Mage = 18.10; 64.4% female) who completed standard surveys and four diary assessments per day over 7 days (N > 4,500 momentary observations). First, to measure affect reactivity, we assessed whether perceived stress was associated with negative affect at the momentary level during high school (senior year). Second, we tested whether affect reactivity predicted internalizing symptoms during the first year of college. Third, we tested whether perceived family or peer support buffered the negative consequences of affect reactivity. Results indicated statistically significant within- and between-person associations between stress and negative affect. Moreover, affect reactivity significantly predicted depressive, but not anxiety, symptoms. Buffering was found for family, but not peer, support. Findings extend previous research by detecting associations between momentary affect reactivity and internalizing symptoms during a sociocultural shift in Latinx adolescents' lives and have implications for culturally appropriate programs to prevent depressive symptoms.

Pediatric recurring pain in the community: the role of children's sleep and internalizing symptoms.

Associations between poor sleep and pain may be amplified for children who also have depressive or anxious symptoms. This study examined associations between child sleep at eight years and recurrent pain at nine years along with the moderating role of internalizing symptoms. Families were from a community-based, ongoing longitudinal study (N = 632 children). At eight and nine years, twins (49.2% female, 56.7% non-Latinx European American, 28.8% Latinx) and caregivers participated in assessments focused on child sleep and pain, respectively. Approximately 53% of children had pain in at least one location at least monthly. Internalizing symptoms at age eight were positively associated with number of pain sites at age nine. Lower sleep efficiencies were associated with more pain sites for children with higher levels of internalizing symptoms. Later midpoint times were associated with more pain sites for children with lower levels of internalizing symptoms. Interventions focused on improving children's pain outcomes may consider targeting sleep behaviors and mental health.

Psychological well-being of ruminative adolescents during the transition to COVID-19 school closures: An EMA study.

INTRODUCTION: Adolescents with moderate-to-severe levels of trait rumination are at heightened risk for psychopathology and may be particularly vulnerable to disruptions caused by the onset of the COVID-19 pandemic. As most past research documenting the impact of COVID-19 on adolescent well-being has been cross-sectional, it is unclear exactly how ruminative adolescents responded to the onset of the pandemic as it unfolded. METHODS: We used ecological momentary assessment (EMA) to explore changes in rumination among adolescents during the initial transition to distance learning in the United States. A subsample of 22 ruminative youth (Mage = 13.58; SD = 0.96; 54.5% male; 86.4% White) from a larger study provided EMA data throughout January-April 2020 (M responses per participant = 105.09, SD = 65.59). Following school closures, we hypothesized that adolescents would report greater rumination (i.e., focusing on emotions and problems) and depressive symptom level would moderate this effect. RESULTS: Surprisingly, rumination decreased, and this effect was moderated by depressive symptom level for emotion-focused rumination, i.e., those with average and below-average depressive symptoms experienced decreases in rumination. CONCLUSIONS: These results suggest that the first wave of stay-at-home orders and the transition to distance learning were not immediately distressing to vulnerable adolescents. However, more research is needed to determine whether the results from recent research are generalizable to other adolescents and to examine the long-term impact of the pandemic on adolescent well-being.

Daytime sleepiness underlies the link between adverse parenting and youth psychopathology among adolescent girls.

INTRODUCTION: Adverse parenting is associated with sleep problems in adolescence, including sleep quality, inadequate sleep, and daytime sleepiness. Adolescents who experience sleep problems are at greater risk for developing internalizing and externalizing problems. However, research on the intervening role of sleep in the link between adverse parenting and youth psychopathology remains limited. The present study aimed to examine the indirect effects of adverse parenting on youth internalizing and externalizing psychopathology via sleep problems, and to examine the moderating role of gender in associations between parenting and sleep. METHODS: Participants were 101 low-income youth aged 9-12 (52.5% female; 75.2% African-American) and their primary caregivers. Families were from a non-metropolitan region in the Southeastern United States. Data were collected at two time points (T1; Mage = 10.28, SD = 1.2; T2; Mage = 12.08, SD = 1.2). Adverse parenting was measured at T1, youth-reported sleep problems (inadequacy, disturbance) and daytime sleepiness were assessed at T2, and parent-reported internalizing and externalizing symptoms were measured at T2. RESULTS: Daytime sleepiness served as an intervening variable in associations between adverse parenting and internalizing and externalizing problems, but sleep problems did not. This indirect association was moderated by gender, such that the association between adverse parenting and daytime sleepiness only emerged as significant for girls. CONCLUSIONS: These findings suggest that daytime-related sleep behaviors may serve as a mechanism through which harsh or neglectful parenting is related to internalizing and externalizing psychopathology in adolescence, particularly for adolescent girls.

Latino Adolescents' Academic Trajectories over the Transition to Higher Education: Variation by School and Neighborhood Contexts and Familism.

Latino college graduation rates continue to fall behind rates of other racial/ethnic groups, highlighting the importance of understanding risk and protective processes across the transition into higher education. The current study examined changes in socio-cultural contexts (i.e., campus and neighborhood co-ethnic composition) and academic achievement across the college transition for Latino adolescents and investigated whether familism values moderated associations. Participants were 188 Latino late-adolescents (Mage = 18.12; SD = 0.40; 62.9% female). Greater campus incongruency (i.e., decrease in co-ethnic composition) was associated with lower achievement for adolescents with low familism values, but not those with average or high levels. Change in neighborhood co-ethnic composition was not associated with achievement. Moving to incongruent campus contexts may be risky for Latino youth who report low levels of familism values, underscoring the importance of sociocultural protective processes in person-context transitions.

Daily Family Connection and Objective Sleep in Latinx Adolescents: The Moderating Role of Familism Values and Family Communication.

Spending time with family ("family connection") is a salient aspect of adolescents' daily lives linked with healthy sleep. Less is known regarding the unique effects of parent and sibling connection on sleep. This study examined daily and average associations between parent/sibling connection and objective sleep (duration, efficiency) in a sample of Latinx adolescents (N = 195; Mage = 18.11, SD = 0.41; 65.6% female) and explored familism values and family communication as moderators. Adolescents slept longer on days that they spent more time with siblings, and youth who typically spent more time with parents had longer sleep durations. Family communication and familism-obligation moderated associations between family connection and sleep. These results provide support for the role of family interactions in promoting healthy sleep among Latinx adolescents.

School Readiness and Achievement in Early Elementary School: Moderation by Students' Temperament.

The goals of this study were to examine the longitudinal relations between school readiness and reading and math achievement and to test if these relations were moderated by temperament. The sample included socio-economically and ethnically diverse twins (N=551). Parents reported on school readiness when children were five years old. Teachers reported on temperament (effortful control, anger, and shyness) three years later. Standardized measures of reading and math were obtained when children were eight years old. Effortful control and shyness moderated the effect of school readiness on reading. Prediction of reading from school readiness was strongest when students were high in effortful control and low in shyness. Effortful control and shyness predicted math beyond school readiness. There were no relations involving anger. Findings demonstrate that temperament can potentiate the relations between school readiness and reading and highlight the importance of promoting school readiness and effortful control, while decreasing shyness.

Effortful Control Moderates the Relation Between Electronic-Media Use and Objective Sleep Indicators in Childhood.

Electronic-media use is associated with sleep disruptions in childhood and adolescence, although research relies primarily on subjective sleep. Effortful control, a dimension of self-regulation, may mitigate this association by helping children disengage from and regulate responses to media. We examined associations between media use and multiple actigraph-measured sleep parameters at mean and day levels and tested children's effortful control as a moderator of mean-level relations. We collected actigraph data and parents' diary reports of children's prebedtime television, video-game, laptop, desktop, cell-phone, and tablet use in 547 twin children (7-9 years old; 51.74% female). Mean-level media use was associated with bedtime and sleep duration. For the proportion of nights on which twins used media, but not the average number of media types, effortful control attenuated associations between media use and reduced sleep duration and efficiency. Day-level media use was related only to bedtime. Findings replicate and extend existing research and highlight self-regulation as a potential protective factor.

Reducing cultural mismatch: Latino students' neuroendocrine and affective stress responses following cultural diversity and inclusion reminder.

Cultural mismatch theory suggests that a poor fit between the cultural values endorsed by individuals and the institutions to which they belong results in emotional distress and activation of physiological stress processes, particularly for underrepresented groups. To test a novel paradigm for reducing perceptions of this cultural mismatch, the current experiment evaluated whether reminding first-year Latino university students (N = 84; Mage = 18.56; SD = 0.35; 63.1% female; 85.7% Mexican descent; 65.5% first-generation college students) about institutional support for cultural diversity and inclusion would reduce neuroendocrine and affective responses to psychosocial stress. Prior to completing a modified version of the Trier Social Stress Test, participants were randomly assigned to view either a video conveying university commitment to cultural diversity and inclusion (n = 45) or a control video (n = 39) depicting a campus tour. Five saliva samples assayed for cortisol and corresponding negative affect measures were collected to assess stress reactivity and recovery patterns (pre-task baseline, post-task +30 min, +45 min, +60 min, +75 min). Repeated measures data were analyzed using bilinear spline growth models. Viewing the culture video (compared to control) significantly reduced cortisol reactivity to the TSST and post-task negative affect levels, specifically for students endorsing higher Latino cultural values (e.g., familism, respect). Post-task cortisol levels were also reduced for students endorsing higher U.S. mainstream cultural values (e.g., self-reliance, competition). Results provide novel evidence for cultural diversity in stress responsivity and individual variation in approaches to reduce perceived cultural mismatch.

Children's sleep, impulsivity, and anger: shared genetic etiology and implications for developmental psychopathology.

BACKGROUND: Prior research has established links between poor sleep and problems in emotion regulation. Impulsivity and anger/frustration are core features of child psychopathology. Further, sleep problems are commonly associated with psychopathology. This study examined shared and unique genetic and environmental influences on sleep, impulsivity, and anger/frustration in the middle childhood period with potential ramifications for psychopathology. METHODS: Families (29.9% monozygotic, 38.6% same-sex dizygotic, 31.5% opposite-sex dizygotic) from a longitudinal twin study participated (N = 613 twins). Twins (Mage  = 8.37, SD = 0.66; 49% female; 58% non-Latinx European American, 30% Latinx) wore actigraph watches for seven days to assess sleep. Primary caregivers (95.3% mothers) completed standardized questionnaires to assess twins' temperament (impulsivity, anger/frustration). RESULTS: Univariate ACE twin structural equation models indicated strong genetic influences (76%) on impulsivity, whereas the largest proportion of variance in anger/frustration was attributed to the shared environment (56%). Bivariate model fitting indicated that sleep-impulsivity and sleep-anger/frustration associations in children are genetic; thus, a mutual underlying genetic factor likely contributes to the commonality in these associations. CONCLUSIONS: Given evidence that sleep problems, impulsivity, and anger/frustration are mechanisms associated with psychopathology, our findings suggest a genetic commonality and the need to focus on shared and unique risk factors when understanding etiology. Early intervention and prevention efforts should target both sleep problems and high levels of impulsivity and anger/frustration in children, which may have implications for later psychopathology.

Daily rumination about stress, sleep, and diurnal cortisol activity.

Rumination is an involuntary cognitive process theorized to prolong arousal and inhibit proper emotion regulation. Most available research has examined individual differences in cognitive dispositions to ruminate about stress as a risk marker for psychopathology and other health problems. This intensive longitudinal study extended previous research by examining day-to-day associations of rumination about stress with objectively-measured actigraph-based sleep and diurnal salivary cortisol activity. Sixty-one healthy participants (Mage = 20.91) completed up to five ecological momentary assessments (EMA) each day and wore actigraph wristwatches for eight days (N = 488). On three of these days, participants provided five saliva samples assayed for cortisol (N = 910). On average, greater daily stress levels were associated with shorter sleep duration and higher waking cortisol levels. In day-to-day analyses, greater daily stress levels, when combined with ruminating about daily stress more than usual, was associated with higher waking cortisol levels the following morning. Ruminating more than usual about daily stress, in the context of low-stress days, was also associated with flatter diurnal cortisol slopes the next day. These findings highlight the potential influences of daily stress, and rumination about stress, on sleep and diurnal cortisol activity - two important markers of health and well-being.
