Adolescents' Compassion is Distinctively Associated With More Prosocial and Less Aggressive Defending Against Bullying When Considering Empathic Emotions and Costs

INTRODUCTION

Adolescents who witness bullying often stand by passively rather than supporting their victimized peers with prosocial defending. In this study, we investigated whether compassion, as unique from empathic distress and anger and social costs, related to more prosocial and less aggressive defending and passivity.

METHOD

Australian adolescents (N = 210; Mage = 14.66, SD = 1.11, age range = 13-17 years; 56% girls) completed surveys that also included embedded film clips portraying peer social bullying. Adolescents reported their compassion, empathy, perceived costs, and intended defending following each clip, and reported their recent experience with bullying and defending.

RESULTS

A multivariate path model revealed that adolescents higher in compassion, but also in empathic distress and empathic anger, intended more prosocial defending. Yet, only compassion was associated with less aggressive defending and empathic anger was associated with more aggressive defending. Empathic distress and social costs associated with more passivity, but compassion and empathic anger associated with less passivity.

CONCLUSION

This study provides the first evidence of unique and differential associations of empathic distress, empathic anger, compassion, and perceived social costs with different bystander behavior intentions among adolescents. Importantly, the findings support the distinctive role of compassion in constructive prosocial and lower aggressive defending.

Temporal relation between pubertal development and peer victimization in a prospective sample of US adolescents

Peer victimization typically peaks in early adolescence, leading researchers to hypothesize that pubertal timing is a meaningful predictor of peer victimization. However, previous methodological approaches have limited our ability to parse out which puberty cues are associated with peer victimization because gonadal and adrenal puberty, two independent processes, have either been conflated or adrenal puberty timing has been ignored. In addition, previous research has overlooked the possibility of reverse causality-that peer victimization might drive pubertal timing, as it has been shown to do in non-human primates. To fill these gaps, we followed 265 adolescents (47% female) prospectively across three-time points (Mage : T1 = 9.6, T2 = 12.0, T3 = 14.4) and measured self-report peer victimization and self- and maternal-report of gonadal and adrenal pubertal development on the Pubertal Development Scale. Multilevel modeling revealed that females who were further along in adrenal puberty at age 9 were more likely to report peer victimization at age 12 (Cohen's d = 0.25, p = .005). The relation between gonadal puberty status and peer victimization was not significant for either sex. In terms of the reverse direction, the relation between early peer victimization and later pubertal development was not significant in either sex. Overall, our findings suggest that adrenal puberty status, but not gonadal puberty status, predicted peer victimization in females, highlighting the need to separate gonadal and adrenal pubertal processes in future studies.

The Social Side of Sleep: A Systematic Review of the Longitudinal Associations between Peer Relationships and Sleep Quality

In adolescence, peer relationships become crucial since youths start to rely on their peers for support. Thus, multiple facets of adolescents' well-being are affected by their peer relationships. In this vein, one of the central well-being aspects that could be affected by the peer relationships of adolescents is sleep quality. Nevertheless, it is still unclear how multiple peer relationship factors (i.e., positive, negative, emotional, and behavioral issues related to peer relationships) are intertwined with adolescents' sleep quality. For this reason, this systematic review with meta-analysis aims to summarize longitudinal studies to uncover how the interplay between peer relationship factors and adolescents' sleep quality unfolds over time. Nineteen longitudinal studies involving a total of 21,232 adolescents were included. Overall, findings from this review showed that (a) positive peer relationships and sleep quality were not associated over time; (b) negative peer relationships and sleep quality were bidirectionally associated over time; (c) few studies evaluated the bidirectional relations between emotional and behavioral issues and sleep quality, showing links with sleep schedule and duration, but not with sleep quality. Meta-analytic results were discussed, considering their implications.

Sibling, Peer, and Cyber Bullying Among Children and Adolescents: Co-occurrence and Implications for Their Adjustment

Bullying across the sibling, peer, and cyber context has consistently been associated with a range of long-term health and well-being consequences for children and adolescents. Although research examining different bullying forms simultaneously in the same study are emerging, it remains unclear to what extend sibling, peer, and cyber bullying co-occur and in what ways they are associated. Moreover, previous work has demonstrated that children and adolescents who experience multiple forms of victimization are at a particular risk of adverse outcomes. However, whether different constellations of co-occurring bullying forms have differential impacts has not yet been investigated sufficiently. The aim of the present study was to examine the frequencies of isolated and co-occurring sibling, peer, and cyber bullying as well as to explore their independent and cumulative relationships with child adjustment. This study was based on a sample of 329 children and adolescents aged between 9 and 15. Bullying experiences across the sibling, peer, and cyber context in the previous 6 months were assessed via self-report. Youth further reported on emotional problems, conduct problems, sleep problems, and academic achievement via an online questionnaire. Sibling, peer, and cyber bullying were uniquely associated with child outcomes. A cumulative relationship between bullying victimization across contexts and emotional problems, conduct problems, and sleep problems could be identified, while bullying perpetration across contexts was only linked to more conduct problems in a cumulative manner. The findings have important practical implications arguing for the adoption of a holistic approach toward bullying in prevention and intervention.

Violent victimisation trajectories from adolescence through adulthood: consequences for sleep problems

BACKGROUND

Violent victimisation is a stressful experience that has been linked with sleep problems among children, adolescents and adults. However, prior research has not assessed how victimisation trajectories across different stages of the life-course correspond to sleep outcomes. The present study assesses how trajectories of violent victimisation from adolescence to middle adulthood correspond to sleep behaviours in adulthood.

METHODS

Data are from fives waves of the National Longitudinal Study of Adolescent to Adult Health (N=6015). Semi-parametric group-based trajectory modelling was used to estimate violent victimisation trajectories from adolescence to middle adulthood. Multinomial logistic regression was used to assess the association between sleep quantity and quality across violent victimisation trajectories.

RESULTS

The findings demonstrate that the relationship between violent victimisation and sleep in adulthood is not consistent across all victimisation trajectories. Rather, sleep quality and quantity are the worst among those who persistently experience violent victimisation from adolescence through adulthood.

CONCLUSION

Persistent exposure to violence can be a particularly damaging experience with consequences for sleep quantity and quality. Establishing interventions that reduce violent victimisation across the life-course and promote positive sleep behaviours among those with a history of victimisation are important public health measures.

Peer Victimization Exposure and Subsequent Substance Use in Early Adolescence: The Role of Sleep Problems

While sleep problems are positively associated with both peer victimization and substance use, previous studies largely have ignored the indirect role sleep problems may play in this association. This three-wave longitudinal study aimed to determine whether sleep problems might link peer victimization to subsequent substance use. Participants were 986 youth (53.7% female, M_age = 12.32 [SD = 0.54 years], 55.6% White, 24.4% Latinx, 22.8% African American/Black, 11.1% Multiracial/Multiethnic, 13.4% Asian/Pacific Islander, and 6.4% Native American) from three U.S. public middle schools. A structural equation model controlling for multiple potential confounds revealed an indirect effect of peer victimization on substance use through sleep problems. Multiple group analyses indicated that the indirect effect was larger for females than for males. Effects did not differ across school socioeconomic level. The results provide further support to include peer victimization when considering factors that may influence adolescent sleep issues and subsequent substance use.
