Parental management of peers and autonomic nervous system reactivity in predicting adolescent peer relationships

The association between peer rejection and behavior problems of migrant adolescents in China: A moderated mediation model of delinquent peer affiliation and parenting

Facing a stressful environment of peer rejection and discrimination, Chinese migrant adolescents are at high risk of developing behavior problems while receiving insufficient family support. In this context, the current study aimed to explore the pathway from peer rejection to adolescent behavior problems via the mediating role of delinquent peer affiliation and with the moderating roles of parental company and parental monitoring taken into consideration. A sample of 2041 migrant adolescents (46.2% female, mean age = 13.595) was drawn from the first and second waves of the China Education Panel Survey (CEPS) for running a moderated mediation model. The results demonstrated that peer rejection positively predicted behavior problems through the mediator of delinquent peer affiliation (indirect effect = 0.007, 95% CI = [0.003, 0.014]). This mediating mechanism was moderated by parental company and by parental monitoring. Our study deepened the theoretical understanding and application of the general strain theory by showing how the interaction of peer stressors and parenting elements affected the behavior of migrant adolescents in a Chinese context. Further studies could pay more attention to the dynamic interplay between the family and peer systems, especially for rejected and marginalized adolescent groups. Limitations and implications for future school-based and family-based practices are also discussed.

Racial differences in sympathetic nervous system indicators: Implications and challenges for research

Growing evidence indicates the presence of racial differences in sympathetic nervous system (SNS) functioning, yet the nature of these differences is unclear and appears to vary across different indices of SNS activity. Moreover, racial differences among commonly used indices of SNS activity are under-investigated. This systematic review examines racial differences among widely used resting SNS indices, such as electrodermal activity (EDA), pre-ejection period (PEP), and salivary alpha-amylase (sAA). Our review reveals that Black participants have consistently been found to display lower resting EDA compared to White participants. The few studies that have investigated or reported racial differences in PEP and sAA yield mixed findings about whether racial differences exist. We discuss potential reasons for racial differences in SNS activity, such as index-specific factors, lab confounds, psychosocial environmental factors, and their interactions. We outline a framework characterizing possible contributors to racial differences in SNS functioning. Lastly, we highlight the implications of several definitional, analytic, and interpretive issues concerning the treatment of group differences in psychophysiological activity and provide future recommendations.

A systematic review and meta-analysis of the association between parenting and child autonomic nervous system activity

Parental socialization may influence the development of children's autonomic nervous system (ANS), a key stress-response system. However, to date no quantitative synthesis of the literature linking parenting and child ANS physiology has been conducted. To address this gap, we conducted a pre-registered meta-analysis. A systematic review of the literature identified 103 studies (n = 13,044 participants) with available effect sizes describing the association between parenting and either parasympathetic nervous system (PNS) or sympathetic nervous system (SNS) activity in children. The overall analysis revealed non-significant associations between parenting and child ANS physiology on average. However, moderation analyses revealed a positive association between more positive parenting and higher resting PNS activity that was stronger when a study was experimental rather than correlational, and when the sample included children with a clinical condition. In conclusion, well-controlled experimental studies show that positive parenting is associated with the development of higher resting PNS activity, an effect that may be stronger among children who are at elevated developmental risk.

Parental Self-Efficacy and Physiological Responses to Stress among Mothers of Early Adolescents

Little research addresses how parental self-efficacy is related to stress responses, and no research does so among parents of early adolescents. To fill this research gap, the current study examined the association between maternal self-efficacy and physiological stress responses during early adolescence. Participants were 68 mother-early adolescent dyads with youth in the 6th grade (M = 11 years; 56% female). Physiological responses (i.e., skin conductance, respiratory sinus arrythmia, cortisol) were measured before and after mothers observed their children engage in a modified Trier Social Stress Test for Children. Mothers reported on parental self-efficacy. Mothers with higher parental self-efficacy exhibited a more moderate skin conductance response to the speech portion of the task, and a smaller increase in cortisol, compared to mothers with lower parental self-efficacy. Respiratory sinus arrhythmia change was not related to parental self-efficacy. The findings are consistent with a "caring but confident" physiological profile among mothers with high parental self-efficacy, suggesting that greater confidence about parental influence might reduce parents' experience of stress/anxiety as they observe children face certain challenges.

Associations between classroom climate and children's externalizing symptoms: The moderating effect of kindergarten children's parasympathetic reactivity

Classrooms are key social settings that impact children's mental health, though individual differences in physiological reactivity may render children more or less susceptible to classroom environments. In a diverse sample of children from 19 kindergarten classrooms (N = 338, 48% female, M age = 5.32 years), we examined whether children's parasympathetic reactivity moderated the association between classroom climate and externalizing symptoms. Independent observers coded teachers' use of child-centered and teacher-directed instructional practices across classroom social and management domains. Children's respiratory sinus arrhythmia reactivity to challenge tasks was assessed in fall and a multi-informant measure of externalizing was collected in fall and spring. Both the social and the management domains of classroom climate significantly interacted with children's respiratory sinus arrhythmia reactivity to predict spring externalizing symptoms, controlling for fall symptoms. For more reactive children, as classrooms shifted toward greater proportional use of child-centered methods, externalizing symptoms declined, whereas greater use of teacher-dominated practices was associated with increased symptoms. Conversely, among less reactive children, exposure to more teacher-dominated classroom management practices was associated with lower externalizing. Consistent with the theory of biological sensitivity to context, considering variability in children's physiological reactivity aids understanding of the salience of the classroom environment for children's mental health.

Parenting, deviant peer affiliation, and externalizing behavior during adolescence: processes conditional on sympathetic nervous system reactivity

BACKGROUND

This study examined associations between permissive parenting, deviant peer affiliations, and externalizing behavior across mid to late adolescence in a plausible indirect effects model of change over time with deviant peer affiliation serving as the mediator. We also evaluated potential conditional indirect effects wherein these relationships may be moderated by sex and sympathetic nervous system (SNS) activity, indexed by skin conductance level (SCL) reactivity.

METHOD

Participants included 242 community-sampled adolescents (M = 15.79 years; 48% boys; 66% European American, 34% African American) with two additional longitudinal assessments lagged by 1 year. Permissive parenting, SCL reactivity, and sex were considered as time invariant predictors of repeated measures of deviant peer affiliation and externalizing behavior in latent growth models that tested whether any of the direct or indirect associations were conditional on sex or SCL reactivity.

RESULTS

Evidence was found for indirect effects of permissive parenting on externalizing behavior via deviant peer affiliation, but only for males with lower SCL reactivity to stress. Additionally, these effects were found on latent intercepts, but not slopes indexing change over time, perhaps reflecting established individual differences in relationships among these variables.

CONCLUSIONS

Findings are discussed in the context of biosocial models of adolescent development and risk factors that may inform interventions for vulnerable youth.
