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.

Concordance in parent-child and sibling actigraphy-measured sleep: Evidence among early adolescent twins and primary caregivers.

STUDY OBJECTIVES: Growing evidence suggests concordance between parent and youth sleep. However, no known study has simultaneously examined concordance among siblings' sleep patterns. This study investigated daily and average concordance in (1) parent-youth and (2) sibling actigraphy-measured sleep, as well as the degree to which sibling concordance varied by sleeping arrangements. METHODS: 516 twin siblings (Mage = 10.74, 51% female; 30% monozygotic (MZ) twin pairs, 37% same-sex dizygotic pairs (DZ-ss), 33% opposite-sex DZ pairs (DZ-os)) and their primary caregivers (Mage = 40.59, 95% female) wore wrist-based accelerometers for 7 consecutive nights to measure sleep duration, efficiency, midpoint time, and latency. Primary caregivers also reported on demographics, youth pubertal status, and room-sharing. Two-level multilevel models were estimated to examine daily and average concordance in parent-youth and sibling sleep. RESULTS: Daily concordance was observed between parent and youth sleep duration and midpoint; average concordance was found for sleep duration, midpoint, and latency. Within sibling dyads, daily and average concordance was evident across all sleep parameters (duration, efficiency, midpoint, latency), with generally stronger concordance patterns for MZ than DZ twin pairs, and for twins who shared a room with their co-twin. CONCLUSIONS: This is the first known study to document concordance among parent-youth and siblings' actigraphy-measured sleep within the same study (i.e., triad). Our findings can help inform the development of family-level interventions targeting daily and overall sleep hygiene.

Does stress predict the development of internalizing symptoms in middle childhood? An examination of additive, mediated, and moderated effects of early family stress, daily interpersonal stress, and physiological stress.

Early life stress, daily life experiences, and the stress responsive hypothalamic-pituitary-adrenal (HPA) axis have each been examined as predictors of the development of psychopathology. Rarely have researchers attempted to understand the covariation or interaction among these stress domains using a longitudinal design in the prediction of symptoms of internalizing psychopathology, particularly during childhood. This study examined early family stress, daily interpersonal stress, indicators of diurnal cortisol, and internalizing symptoms in a racially/ethnically and socioeconomically diverse sample of twins (N = 970 children; Mage at outcome = 9.73; 52% female; 23.7% Hispanic/Latino, 58.8% White; 30% below middle class; Lemery-Chalfant et al., 2019). An additive model of stress, a stress mediation model, and a stress sensitization framework model each delineated potential pathways linking stress and internalizing symptoms. Supporting additive pathways, multilevel models showed that all 3 stress indicators uniquely predicted internalizing symptoms. There was a significant indirect path from early family stress to 9 year internalizing symptoms through interpersonal stress, supporting stress mediation. Family stress moderated the association between interpersonal stress and internalizing symptoms, though not in the direction that would support stress sensitization. Child stress, including daily interpersonal stress and HPA axis activity, and internalizing symptoms are prevalent and family stress is a significant precursor to child internalizing symptoms across child development.

The onset of pubertal development and actigraphy-assessed sleep during middle childhood: Racial, gender, and genetic effects.

OBJECTIVE: This study (1) examined pubertal development in relation to actigraphy-assessed sleep in twin children, and tested whether associations differed by child race and gender, (2) modeled genetic and environmental influences on pubertal development and sleep indicators, and (3) examined genetic and environmental influences on the covariation of puberty and sleep. DESIGN: The classic twin design was used to examine genetic and environmental contributions to puberty and sleep and their associations. SETTING: Data were collected from community-dwelling urban and rural families of twins in the southwestern U.S. PARTICIPANTS: The racially and socioeconomically diverse sample included 596 twin children (Mage = 8.41, SD = 0.69; 51.7% female; 66.3% white; 33.7% Hispanic; 170 monozygotic, 236 same-sex dizygotic, 188 opposite-sex dizygotic). MEASUREMENTS: Pubertal development was assessed via parent report. Children wore actigraph watches for 7 nights (M = 6.81, SD = 0.67) to capture sleep duration, efficiency, midpoint, onset latency, and duration variability. RESULTS: In contrast to extant literature with older youth, more advanced pubertal development was associated with longer sleep durations in Hispanic and white girls and higher sleep efficiency in white girls, though Hispanic girls demonstrated later sleep midpoints. Pubertal development was moderately heritable and there was a genetic influence on the covariance between puberty and sleep indicators. CONCLUSIONS: This was the first study to examine the genetic and environmental influences on the covariation between puberty and sleep, and found genetic underpinnings between pubertal development and actigraphy-assessed sleep duration and efficiency, though sleep and puberty were almost entirely independent in twins at this age.

The multiplicative effect of stress and sleep on academic cognitions in Latino college students.

Latino students are increasingly represented in higher education within the United States, but remain one of the groups least likely to graduate from a four-year institution. Stress and sleep are factors that have been implicated in students' academic success. This study examined concurrent and longitudinal interactive effects of stress and sleep on academic cognitions in a sample of 196 Latino students (Mage = 18.95; 64.4% female) in their second and third semester of college. Stress and actigraphy-measured sleep (duration, efficiency, midpoint, midpoint-variability) were measured in the second semester and academic cognitions (engagement, motivation, self-efficacy) were measured in the second and third semesters. Structural equation modeling revealed that higher stress was concurrently related to lower academic cognitions for students with consistently delayed sleep timings (e.g., later average midpoints) and longitudinally related to reduced academic functioning for students with lower sleep efficiency. These findings can inform programs that target stress-reduction and sleep hygiene among incoming college students.

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.

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.

The effectiveness of parental distraction during children's acute pain: The moderating effect of socioeconomic status.

BACKGROUND: Parental responses to children's pain shape how children interpret and cope with pain symptoms through parental modelling and operant conditioning. Evidence suggests that parental distraction is effective in reducing children's acute pain responses, but findings are inconsistent across pain tolerance, intensity and unpleasantness, and are limited to samples of primarily middle and upper-middle class families. Although socioeconomically disadvantaged families may have fewer psychological resources to cope with pain, no studies have examined whether the utility of parent distraction varies by family socioeconomic status (SES). The current study tested the hypothesis that relations between parental distraction and acute pain responses in children vary by family SES, with children from higher versus lower SES families experiencing more substantial benefits. METHODS: Children's pain symptoms and parents' use of verbal distraction during a cold pressor task were examined in a community sample of 530 twin children aged 7-12 years old and their primary caregivers. RESULTS: Parental distraction was positively associated with children's pain tolerance and unrelated to intensity and unpleasantness, but these associations are qualified by significant moderation. In families with higher SES, parental distraction was an effective technique in children's pain management, associated with more pain tolerance and less pain intensity and unpleasantness. However, for families with lower SES, these same benefits were not present. CONCLUSIONS: Findings suggest that the effectiveness of parental distraction for children's acute pain may depend on family SES. SIGNIFICANCE: Study findings suggest that the effects of parental distraction on children's responses to an acute pain task vary by family SES. Although parental distraction may be effective for higher SES children, further research is needed to identify whether and why distraction may not be beneficial for lower SES families.
