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[superscript 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…

This study's goal was to identify patterns of risk and promotive factors across multiple social-ecological domains and their associations with adolescents' problem behaviors (aggression, substance use, and other delinquent behaviors), victimization, and distress symptoms. Participants were a mostly African American (79%) sample of 2711 middle…

Latent growth curve modeling was used to investigate the longitudinal link between attachment, effortful control (EC), and maladaptive development during middle childhood. In a community sample, children (Time 1: n = 157; M[subscript age] = 10.91) and their mothers were examined three times over a two-year period. Attachment was operationalized at…

Classroom incivility is a critical concept relating to the academic and psychosocial well-being of children and youth. However, there has yet to be research investigating whether there are social benefits to this behavior in early adolescence. Therefore, the goal of this study was to explore the relationship between classroom incivility and…

Based on the temporal framework of transition experiences, this study tested time-graded patterns of family resource effects on children's and early adolescents' psychological adjustment during a time of multiple transitions. Using data of a longitudinal study including 2,020 German children covering the age span between 8 and 12 (n[subscript…

We tested whether adoptive parenting played a role in the association between pre-adoption experiences and children's adaptive (responsiveness) and maladaptive (internalizing and externalizing behavioral problems, attention and sleep problems) behavioral adjustment over time. Ten-year-old girls, adopted at 13 months from institutional care (n =…

Few longitudinal studies examine how "changes" in parent-child relationships are associated with changes in youth internalizing problems. In this longitudinal study, we investigated how developmental trends (linear change) and year-to-year lability (within-person fluctuations) in parental warmth and hostility across Grades 6 to 8 predict…

The present study examined the relations between financial entitlement and adolescent gratitude, prosocial behavior, and aggression; and the mediating role of sympathy. The sample consisted of 321 children (160 boys, M[subscript age at Time 2] = 12.29, SD = 1.02) from Times 2, 3, and 4 of the Flourishing Families Project. Adolescents reported on…

Black South Africans are disproportionately affected by HIV compared with White counterparts. In their unique social context, South African families affected by HIV are vulnerable to adverse psychosocial effects. U.S.-based and emerging South African research suggests mothers living with HIV may experience compromised parenting. In the United…

Black and Latinx youth are situated in a maladaptive discriminatory context in the United States; however, prosociality may be one way that youth can promote their own positive development in the face of these experiences. We examined the longitudinal associations between discrimination and prosociality among 380 Black and Latinx early adolescents…

In this study, we examined the relations between perceived social-class discrimination, attachment, and behavior problems in a sample of Chinese migrant children in Beijing (age [X-bar] = 11.48, SD = 1.12; n = 179). Data were collected from two migrant schools in Beijing. The participants completed measures of perceived social-class…

In line with family systems theory, we examined patterns of hostile interactions within families and their associations with externalizing problems among early-adolescent children. Using hostility scores based on observational data of six dyadic interactions during a triadic interaction (n = 462; i.e., child-to-mother, mother-to-child,…

A growing body of research has acknowledged the heterogeneity of subclinical social anxiety, identifying a subgroup of individuals who exhibit high levels of impulsivity. In a sample of Swedish early adolescents (N=2,509, M[subscript age]=13.64; 52.8% girls), we conducted latent transition analyses (LTA) to identify four classes of subclinical…

The present cross-sectional study aimed to examine whether characteristics of the parent-child relationship in adolescence are important for adjustment and identity development. Participants were recruited from schools in central Sweden for a larger longitudinal study when the cohort was 13- to 14-year-olds (N = 3,667). Characteristics of the…

Inconsistencies exist regarding the relation between physical activity (PA) and internalizing symptomology in early adolescence, and there is need for investigation of potential moderators that may account for these discrepancies. The current study utilized a Self-Determination Theory Framework to investigate the main effects of five key…
