The Role of Sleep in Links Between Daily Interpersonal Stress and Internalizing and Externalizing Symptoms During Middle Childhood.

Background: Interpersonal stress has been consistently linked with poorer adjustment, and healthy sleep may play a promotive or protective role in this relation. However, little is known regarding such associations among children. The current study examined longitudinal associations between daily interpersonal stress, sleep, and internalizing/externalizing symptoms during middle childhood.

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 ( = 18.

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.

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 ( = 970 children; = 9.

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.

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 (= 18.

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.

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; M = 18.

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).

Arizona Twin Project: Specificity in Risk and Resilience for Developmental Psychopathology and Health.

The Arizona Twin Project is an ongoing longitudinal study designed to elucidate gene-environment interplay underlying the development of risk and resilience to common mental and physical health problems during infancy, childhood and adolescence. Specificity of risk is carefully examined across mental and physical health and how these influences vary across socioeconomic and sociocultural environments. Participants are a sample of approximately 700 twins (31% Latinx) recruited from birth records in the state of Arizona, USA.

Altered Neural Connectivity in Females, But Not Males with Autism: Preliminary Evidence for the Female Protective Effect from a Quality-Controlled Diffusion Tensor Imaging Study.

Previous studies using diffusion tensor imaging (DTI) to investigate white matter (WM) structural connectivity have suggested widespread, although inconsistent WM alterations in autism spectrum disorder (ASD), such as greater reductions in fractional anisotropy (FA). However, findings may lack generalizability because: (a) most have focused solely on the ASD male brain phenotype, and not sex-differences in WM integrity; (b) many lack stringent and transparent data quality control such as controlling for head motion in analysis. This study addressed both issues by using Tract-Based Spatial Statistics (TBSS) to separately compare WM differences in 81 ASD (56 male, 25 female; 4-21 years old) and 39 typically developing (TD; 23 males, 16 females; 5-18 years old) children and young people, carefully group-matched on sex, age, cognitive abilities, and head motion.
