There has been concern about the potential sequelae of mild traumatic brain injury (mTBI) in children. This study used data from the Adolescent Brain Cognitive Development^SM (ABCD) study to investigate associations between mTBI and behavior and sleep in school-aged children. Generalized additive mixed models were run to examine the association between TBI and parent-reported Child Behavior Checklist and Sleep Disturbance Scale for Children scores. mTBI with or without loss of consciousness (LOC) in 9- and 10-year old children was associated with 1) higher internalizing, externalizing and total problems and 2) greater sleep disturbance scores on the CBCL. The study also demonstrated a higher incidence of mTBI with and without LOC in boys compared to girls. This study shows a statistically significant but modest association between mTBI and behavioral and sleep changes, suggesting that in a non-clinical, sociodemographically diverse community sample of school-aged children mTBI does not result in clinically significant behavioral or psychological sequelae.

Bias-based aggression at school in the form of homophobic name-calling is quite prevalent among early adolescents. Homophobic name-calling is associated with low academic performance, higher risky sexual behaviors, and substance abuse, among other adverse outcomes. This longitudinal study examined risk and protective factors across multiple domains of the social ecology (individual, peer, family, school and community) and levels of analysis (within- and between-person) associated with homophobic name-calling perpetration and victimization. Students from four middle schools in the U.S. Midwest (N = 1,655; $\overline{X}$ age = 12.75; range = 10-16 years) were surveyed four times (Spring/Fall 2008, Spring/Fall 2009). For homophobic name-calling perpetration, significant risk factors included impulsivity, social dominance, traditional masculinity, family violence, and neighborhood violence; while empathy, peer support, school belonging, and adult support were significant protective factors. For homophobic name-calling victimization, significant risk factors included empathy (between-person), impulsivity, traditional masculinity, family violence, and neighborhood violence, while empathy (within-person), parental monitoring, peer support, school belonging, and adult support were significant protective factors.

Among U.S. Mexican adolescents living in established immigrant communities, high familism values are positively associated with compliant, emotional, and dire prosocial behaviors via sociocognitive and cultural psychological mechanisms. Less is known about the behavioral mechanisms that may explain these associations, or about prosocial behaviors among U.S. Latinxs residing in emerging immigrant destinations. We examined the cross-sectional, intervening variable associations among familism values, family assistance behaviors, and culturally salient prosocial behaviors among 547 U.S. Latinx adolescents residing in an emerging immigrant destination (M age = 12.8 years; 55.4% girls). Familism values and family assistance behaviors promoted emotional and dire prosocial behaviors for boys and girls, and promoted compliant prosocial behaviors for boys only. Familism also had direct associations with all three prosocial behaviors for boys and girls. Family assistance behaviors may be a mechanism via which adolescents develop compliant, emotional, and dire prosocial behaviors.

This study using PROSPER data (N = 977, age 11.5 to age 15) investigated the longitudinal within-family associations between parent-reported parental monitoring and adolescent aggression. Importantly, this study is the first one to examine parent gender and adolescent gender differences on these within-family associations. Results differed between mothers and fathers. There was a negative, bidirectional within-family association between maternal monitoring and adolescent aggression, such that more maternal monitoring than usual was associated with fewer adolescent aggressive behavior problems than usual within the same family, and vice versa. In contrast, during mid-adolescence, a positive, bidirectional within-family association between paternal monitoring and adolescent males' aggression was found, such that more paternal monitoring than usual was related to more adolescent males' aggression than usual within the same family, and vice versa. Practical implications on intervention strategies are discussed.
