Neural Reward Anticipation Moderates Longitudinal Relation between Parents' Familism Values and Latinx American Youth's School Disengagement.

Parents' familism values predict a variety of Latinx American youth's academic adjustment. However, it is unclear how cultural values such as familism interact with youth's brain development, which is sensitive to sociocultural input, to shape their academic adjustment. Using a sample of 1916 Latinx American youth (mean age = 9.90 years, SD = .63 years; 50% girls) and their primary caregivers (mean age = 38.43 years, SD = 6.81 years; 90% mothers) from the Adolescent Brain Cognitive Development Study, this study examined the longitudinal relation between parents' familism values and youth's school disengagement, as well as the moderating role of youth's neural sensitivity to personal reward. Parents' familism values predicted youth's decreased school disengagement 1 year later, adjusting for their baseline school disengagement and demographic covariates. Notably, this association was more salient among youth who showed lower (vs. higher) neural activation in the ventral striatum and the lateral OFC during the anticipation of a personal reward. These findings underscore the protective role of familism for Latinx American youth, highlighting the necessity of developing culturally informed interventions that take into consideration a youth's brain development.

Longitudinal study of peer victimization, social support, and mental health during early adolescence.

BACKGROUND: Peer victimization predicts the development of mental health symptoms in the transition to adolescence, but it is unclear whether and how parents and school environments can buffer this link. METHODS: We analyzed two-year longitudinal data from the Adolescent Brain Cognitive Development (ABCD) study, involving a diverse sample of 11 844 children across the United States (average at baseline = 9.91 years; standard deviation = 0.63; range = 8.92-11.08; complete case sample = 8385). Longitudinal associations between peer victimization and two-year changes in mental health symptoms of major depression disorder (MDD), separation anxiety (SA), prodromal psychosis (PP), and attention-deficit/hyperactivity disorder (ADHD) were examined including a wide range of covariates. Mixed linear models were used to test for the moderating effects of parental warmth and prosocial school environment. RESULTS: 20% of children experienced peer victimization. Higher exposure to peer victimization was associated with increases in MDD, SA, and ADHD symptoms. Parental warmth was associated with decreases in MDD symptoms but did not robustly buffer the link between peer victimization and mental health symptoms. Prosocial school environment predicted decreases in PP symptoms and buffered the link between peer victimization and MDD symptoms but amplified the link between peer victimization and SA and ADHD symptoms. CONCLUSIONS: Peer victimization is associated with increases in mental health symptoms during the transition to adolescence. Parental warmth and prosocial school environments might not be enough to counter the negative consequences of peer victimization on all mental health outcomes.

Family obligation in Chinese adolescents: Consequences and parental antecedents.

Adolescents' family obligation is a cultural strength that shows enduring prevalence in China. Given that the meaning of family obligation has undergone rapid changes in recent decades, it is crucial to examine the role of family obligation in adolescent adjustment in contemporary China. More importantly, although past research has investigated the consequences of family obligation on adolescents' adjustment, little is known about the antecedents of Chinese adolescents' family obligation. Using a two-wave longitudinal sample of 450 Chinese adolescents (mean age = 13.78 years, SD = .71 years; 49% female) and their parents, the current research explored two questions. First, this study examined the role of family obligation in adolescents' academic achievement, externalizing problems, and internalizing problems over early adolescence. Second, this study explored the role of parents in predicting Chinese adolescents' family obligation, specifically whether parental expectations or parental acceptance was predictive of adolescents' family obligation over time. Third, this study investigated whether family obligation is an underlying mechanism between parenting and Chinese adolescents' adjustment. Results showed that Chinese adolescents' family obligation was longitudinally associated with increased academic achievement and reduced externalizing problems. Moreover, perceived parental acceptance, but not parental expectations, was longitudinally associated with Chinese adolescents' greater family obligation. Notably, family obligation mediated the longitudinal effect of parental acceptance on Chinese adolescents' externalizing problems. By studying both the consequences and antecedents of Chinese adolescents' family obligation, this study helps provide a comprehensive understanding of this cultural strength.

Parental warmth buffers the negative impact of weaker fronto-striatal connectivity on early adolescents' academic achievement.

In past decades, the positive role of self-control in students' academic success has attracted plenty of scholarly attention. However, fewer studies have examined the link between adolescents' neural development of the inhibitory control system and their academic achievement, especially using a longitudinal approach. Moreover, less is known about the role of parents in this link. Using large-scale longitudinal data from the Adolescent Brain Cognitive Development (ABCD) study (N = 9574; mean age = 9.94 years at baseline, SD = .63; 50% girls), the current study took an integrative biopsychosocial approach to explore the longitudinal link between early adolescents' fronto-striatal connectivity and their academic achievement, with attention to the moderating role of parental warmth. Results showed that weaker intrinsic connectivity between the frontoparietal network and the striatum was associated with early adolescents' worse academic achievement over 2 years during early adolescence. Notably, parental warmth moderated the association between fronto-striatal connectivity and academic achievement, such that weaker fronto-striatal connectivity was only predictive of worse academic achievement among early adolescents who experienced low levels of parental warmth. Taken together, the findings demonstrate weaker fronto-striatal connectivity as a risk factor for early adolescents' academic development and highlight parental warmth as a protective factor for academic development among those with weaker connectivity within the inhibitory control system.

The role of neural reward sensitivity in the longitudinal relations between parents' familism values and Latinx American youth's prosocial behaviors.

Past research suggests that parents' familism values play a positive role in Latinx American youth's prosocial tendencies. However, little is known about how individual differences in youth's neural development may contribute to this developmental process. Therefore, using two-wave longitudinal data of 1916 early adolescents (mean age = 9.90 years; 50% girls) and their parents (mean age = 38.43 years; 90% mothers) from the Adolescent Brain Cognitive Development study, this pre-registered study took a biopsychosocial approach to examine the moderating role of youth's neural reward sensitivity in the link between parents' familism values and youth's prosocial behaviors. Results showed that parents' familism values were associated with increased prosocial behaviors among youth two years later, controlling for baseline prosocial behaviors and demographic covariates. Notably, parents' familism values played a larger role in promoting youth's prosocial behaviors among youth who showed lower ventral striatum activation during reward anticipation. Moreover, such association between parents' familism values and youth's later prosocial behaviors was stronger among youth who showed lower levels of prosocial behaviors initially. Taken together, the findings highlight individual differences in neurobiological development and baseline prosocial behaviors as markers of sensitivity to cultural environments with regard to Latinx American youth's prosocial development.

Longitudinal associations between neighborhood safety and adolescent adjustment: The moderating role of affective neural sensitivity.

Research on social determinants of health has highlighted the influence of neighborhood characteristics (e.g., neighborhood safety) on adolescents' health. However, it is less clear how changes in neighborhood environments play a role in adolescent development, and who are more sensitive to such changes. Utilizing the first three waves of data from the Adolescent Brain Cognitive Development (ABCD) project (N = 7932, M (SD) age = 9.93 (.63) years at T1; 51% boys), the present study found that increases in neighborhood safety were associated with decreased adolescent externalizing symptoms, internalizing symptoms, but not sleep disturbance over time, controlling for baseline neighborhood safety. Further, adolescents' insula and anterior cingulate cortex (ACC) reactivity to positive emotional stimuli moderated the association between changes in neighborhood safety and adolescent adjustment. Among youth who showed higher, but not lower, insula and ACC reactivity to positive emotion, increases in neighborhood safety were linked with better adjustment. The current study contributes to the differential susceptibility literature by identifying affective neural sensitivity as a marker of youth's susceptibility to changes in neighborhood environment. The findings highlight the importance of neighborhood safety for youth during the transition to adolescence, particularly for those with heightened affective neural sensitivity.
