Prevalence and correlates of sibling victimization types

The transition from physical sibling abuse to bullying perpetration through trait anger: A longitudinal study

OBJECTIVES

Experiencing physical sibling abuse is a form of family violence that is common but understudied. While it is often perceived as a normative aspect of sibling relationships, there are apparent behavioral consequences. The current study aims to advance the literature by utilizing the displaced aggression model and I3 theory to longitudinally examine trait anger as a pathway linking physical sibling abuse to bullying perpetration.

METHODS

Using data from the Bullying, Sexual, and Dating Violence Trajectories from Early to Late Adolescence in the Midwestern United States, 2008-2013, adolescents (n = 851, M = 14.8 years) completed questionnaires at baseline and were reassessed 6 months later.

RESULTS

Results suggested that when adolescents experience physical sibling abuse, they are more likely to engage in bullying perpetration. Mediation analyses indicated that as adolescents were physically abused by a sibling at home, they were more likely to report higher levels of trait anger, which subsequently increased their risk of engaging in bullying perpetration.

CONCLUSION

These results suggest that experiencing physical sibling abuse has long-term detrimental consequences, including elicitation of trait anger, subsequently predicting bullying perpetration.

Sibling bullying victimization and subjective well-being among children across 13 countries: The mediating roles of perceived social support and the moderating role of uncertainty avoidance culture

BACKGROUND

While sibling bullying victimization has been recognized as a significant factor detrimentally impacting children's subjective well-being, the underlying mechanisms have yet to be fully elucidated.

OBJECTIVE

This study seeks to investigate the potential mediating role of perceived social support, encompassing support from family, friend, teacher, and neighbor, as well as the moderating influence of uncertainty avoidance culture.

PARTICIPANTS AND SETTING

A sample of 19,328 children was obtained from Wave Three of Children's Worlds: International Survey of Children's Well-being in 13 countries.

METHODS

The structural equation model (SEM) was used to investigate the mediating role of perceived social support in the relationship between sibling bullying victimization and children's subjective well-being. The multiple group analysis was carried out to assess the moderating role of uncertainty avoidance culture.

RESULTS

This study reveals a negative association between sibling bullying victimization and children's subjective well-being (β = -0.138, p < 0.001). Perceived support from family, friend, teacher, and neighbor emerges as a mediating mechanism in this relationship. Uncertainty avoidance culture moderates this relationship, and this association is stronger for children raised in a strong uncertainty avoidance culture (β = -0.085, p < 0.001).

CONCLUSIONS

The results of this study contribute to our comprehension of the nexus between sibling bullying victimization and children's subjective well-being. Moreover, this study extends the current body of knowledge by delving into the cultural disparities spanning various countries.

Genetic influences on sibling bullying and mental health difficulties

BACKGROUND

Sibling bullying is associated with mental health difficulties; both in the short and long term. It is commonly assumed that sibling bullying leads to mental health difficulties but additional explanations for the relationship between the two are seldom investigated.

METHODS

To address this gap in knowledge, we used a genetically sensitive design with data from the Avon Longitudinal Study of Parents and Children (maximum N = 3,959, 53% female). At ages 11-13 years, individuals self-reported their involvement in sibling bullying, as a victim and perpetrator, and parents reported on their child's mental health difficulties. Polygenic scores, indices of genetic risk for psychiatric disorders (major depressive disorder and attention deficit hyperactivity disorder) were computed using children's genetic data. Regression and structural equation models were fitted to the data.

RESULTS

Sibling bullying, victimisation and perpetration, and polygenic scores both predicted mental health difficulties in an additive manner but there was no interaction between them. Polygenic scores for mental health difficulties were also associated with sibling bullying.

CONCLUSIONS

These findings suggest that sibling bullying, victimisation and perpetration, is associated with mental health difficulties, even after accounting for some genetic effects. Additionally, the relationship between sibling bullying and mental health difficulties may be, at least partly, due to shared genetic aetiology. One possibility is that genetic risk for mental health difficulties influences the onset of mental health difficulties which in turn make children more susceptible to sibling bullying.

Sibling bullying reported by emerging adults: Profiling the prevalence, roles, and forms in a cross-country investigation

Prevalence estimates of sibling bullying indicate it occurs more frequently and with more negative consequences than peer bullying, yet many countries do not track or investigate the phenomenon. University students from Argentina, Estonia, and the United States were surveyed to investigate their retrospective experiences involving sibling bullying, how often it occurred, the roles held, and the forms communicated. In the aggregated data, roughly 50 % of the sampled emerging adults (N = 3477) reported experience with sibling bullying, with the dual role of bully-victim being the most frequently reported role held by males and females, with the second role being bully for males and victim for females. Verbal forms of bullying were most frequently reported by males and females, with physical, relational, and technological forms occurring less frequently, indicating the importance of studying the messages conveyed during bullying incidents. Variations between biological sex, bullying role and form were detected that indicate siblings experience bullying in ways that are unique from peer bullying. Country comparisons revealed bullying frequencies varied among males and females, suggesting sibling bullying experiences are likely to be culturally influenced. More research is warranted to examine the negative impact bullying has on sibling psycho-social development and the potential transfer to non-familial relationships and contexts. Discussion of these findings and the implications for academics and practitioners alike is provided.

[Emotional Maltreatment of Children and Adolescents - Definitions, Prevalences, Risk Factors and Psychological Consequences]

The aim of this article is to provide an introductory overview of the phenomenon of emotional maltreatment of children and adolescents by presenting national and international literature and, in particular, to illustrate the consequences for the mental health of those affected. First, relevant definitions are made and forms of appearance of emotional child maltreatment are presented. A comparison of national and global prevalences shows that emotional child maltreatment is one of the most prevalent forms of child maltreatment. There are different risk factors that can exist at the level of the parents as well as at the level of the children or the environment. The risk that children and adolescents who have experienced emotional violence will have experienced other forms of childmaltreatment is high.There aremultiple consequences for victims of emotional child maltreatment which can result in different, longterm participatory impairments. Especially the psychological and somatic consequences of emotional childmaltreatment can be compared to the consequences of child sexual abuse and physical child maltreatment. Nevertheless, the significance of emotional maltreatment for affected children and adolescents is still underestimated in practice. Often, the effects of emotionalmaltreatment on those affected are not visible. Froma child and adolescent psychiatric/ psychotherapeutic perspective, the psychological consequences must therefore be clearly stated. Finally, there is a need for a broader understanding of emotional child maltreatment that also includes peer and sibling violence.

The Association Between Child Abuse and Aggressive Behavior: A Three-Level Meta-Analysis

Child abuse is considered to be an essential factor in the development of aggressive behavior. The intensity of the positive relations between child abuse and aggressive behavior differed considerably among researches despite the fact that abundant studies have observed this relation. According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) approach, a three-level meta-analysis was employed to obtain reliable estimates for the sizes of effects and investigate some potential moderators of the relation between child abuse and aggressive behavior. The present study obtained 51 studies (30,566 participants; 680 effect sizes) through performing the detailed literature search. It was found that child abuse was positively associated with aggressive behavior in the current study. In addition, the present meta-analysis observed significant moderating effects for type of child abuse, culture, measurement of child abuse, and publication year in the association between child abuse and aggressive behavior. This study suggests that child abuse is a predictor for the development of aggressive behavior in humans. Moreover, child abuse is an important aspect for consideration in efforts toward strengthening of interventions targeting individuals' aggressive behavior.

Physical and Emotional Sibling Violence in Childhood and Attachment in Close Relationships in Adulthood

Despite the consequences of physical and emotional sibling violence, which can last into adulthood, research examining this form of family violence is minimal compared to child abuse, interpartner violence, and elder abuse. One area that has received scarce attention is the connection between physical and emotional sibling violence and attachment in close relationships in adulthood. This research study examines the association between physical and emotional sibling violence and adulthood attachment in a sample of 2,458 individuals who completed a survey on the sub-Reddit platform "/r/SampleSize: Where your opinions actually matter!" Participants completed items on demographics, frequency of physical and emotional behaviors experienced with a sibling in childhood, and adult attachment. Results found physical and emotional sibling violence in childhood to be associated with attachment in close relationships in adulthood. Frequency of physical and emotional sibling violence in childhood was also associated with comfortability with intimacy and closeness, comfortability of depending and relying on others, and concerns of abandonment and rejection by others in adulthood. The findings underscore the need to not only include physical and emotional sibling violence in future research on attachment but also to examine the connection between these phenomena in diverse samples (ethnicity, sexual orientation). Also highlighted is the need for practitioners to assess sibling relationships when working with children, families, and adults experiencing attachment issues throughout the life course.

The role of sibling aggression during childhood in decision-making during adulthood

Research shows sibling relationships can influence cognitive development, specifically in terms of high-order processes involved in social functioning. These high-order processes take place in the human prefrontal cortex. While prefrontal connectivity can be influenced by factors experienced during developmental phases, it remains unclear how experiences of aggression towards a sibling in childhood can contribute to high-order processes in adulthood, specifically decision-making. Through two studies, we sought to establish a relationship between sibling aggression and decision-making styles reported in adulthood, as well as real-time risky decision-making. Study 1 examined the relationship between childhood experiences of sibling aggression and high-order function, specifically decision-making. Self-reports from 142 adult participants revealed that using sibling aggression to maintain dominance (ESAS; Harrison, Harrison, N. (2017). Sibling aggression: Associations with parenting styles, social dominance behaviour and co-occurring forms of family aggression (Doctoral thesis, University of Central Lancashire, UK). Retrieved from: https://clok.uclan.ac.uk/20917/) was linked to avoidant and spontaneous decision-making (GDMS; Scott & Bruce, Scott and Bruce, Educational and Psychological Measurement 55:818–831, 1995). The findings reported here indicate a possible role of sibling aggression in the development of avoidant and spontaneous decision-making styles. Study 2 investigated the relationship between childhood sibling aggression (ESAS; Harrison, Harrison, N. (2017). Sibling aggression: Associations with parenting styles, social dominance behaviour and co-occurring forms of family aggression (Doctoral thesis, University of Central Lancashire, UK). Retrieved from: https://clok.uclan.ac.uk/20917/) and performance in risky decision-making tasks (IOWA gambling task; Bechara et al., Bechara et al., Brain 123:2189–2202, 2000) among 75 adult participants. It revealed that experiences of sibling aggression did not predict risky decision-making. These findings indicate that the types of decisions made may be influenced by childhood sibling aggression, but not the level of risk involved in decisions made.

Direct and Indirect Paths between Parental Marital Conflict and Children's Sibling Conflict in Chinese Families

Links between parental marital conflict and children's sibling conflict have been well examined; however, the underlying mechanism of this link needs to be further studied. This study investigated the mediating role of parental intervention styles (i.e. child-centered strategies, control strategies, and nonintervention strategies) and children's control behavior toward their sibling between parental marital conflict and children's sibling conflict. We recruited 689 Chinese children (53.7% girls) aged 8-13 years to participate in the study. Results indicated that parental marital conflict, control strategies, nonintervention strategies, and children's control behavior toward sibling were positively associated with sibling conflict among children. Child-centered strategies were negatively correlated with children's sibling conflict. Furthermore, control and nonintervention strategies of parents and control behavior of children toward sibling simultaneously partially mediated between parental marital and child-sibling conflict. The mediating role of child-centered strategies was not significant. These findings suggest that parental strategies of control and nonintervention and children's control behavior toward their sibling may increase the risk of sibling conflict among children after repeated exposure to parental marital conflict. In contrast, child-centered strategies may be a protective factor for children regarding sibling conflict. Current findings confirm the combined effects of parent and child behavior on child-sibling conflict. They also help parents deal with sibling conflict among their children and promote more positive relationships among siblings.

Prevalence and Associated Family Factors of Sibling Bullying Among Chinese Children and Adolescents

Sibling bullying is the most common form of aggression within family worldwide, while the prevalence and correlations of sibling bullying is little known in China. The current research focused on the association between family factors and sibling bullying among Chinese adolescents, and explore sex differences in sibling bullying in the context of Chinese culture. A cross-sectional study was conducted to explore the characteristics of sibling bullying by sampling 6302 children and adolescents who had at least 1 sibling living in the household. Of the participants, 1827 (29.0%) were involved in sibling bullying over the past half year, and pure victims, pure bullies, and bully-victims were 486 (7.7%), 510 (8.1%), and 831 (13.2%), respectively. Family factors of sibling bullying were partly different between boys and girls. Parental absence of both father and mother was a risk factor of being a pure bully and a bully-victim for boys, and of being a pure victim for girls. Parental son preference increased the odds of being a pure victim and a bully-victim for boys, and of being all roles of sibling bullying involvement for girls. Besides, parent–parent violence, parent–child violence, and living with a single parent were risk factors of sibling bullying. The results underline the importance of home environment on sibling relationship, and intervention of sibling bullying should include improving family climate.

Building long-term family resilience through universal prevention: 10-year parent and child outcomes during the COVID-19 pandemic

As the COVID-19 pandemic has been highly stressful for parents and children, it is clear that strategies that promote long-term family resilience are needed to protect families in future crises. One such strategy, the Family Foundations program, is focused on promoting supportive coparenting at the transition to parenthood. In a randomized trial, we tested the long-term intervention effects of Family Foundations on parent, child, and family well-being one to two months after the imposition of a national shelter-in-place public health intervention in 2020. We used regression models to test intervention impact on outcomes reported on by parents in a standard questionnaire format and a series of 8 days of daily reports. We also tested moderation of intervention impact by parent depression and coparenting relationship quality. Relative to control families, intervention families demonstrated significantly lower levels of individual and family problems (general parent hostility, harsh and aggressive parenting, coparenting conflict, sibling relationship conflict, and children's negative mood and behavior problems), and higher levels of positive family relationship quality (positive parenting, couple relationship quality, sibling relations, and family cohesion). For some outcomes, including coparenting conflict, harsh parenting, and child behavior problems, intervention effects were larger for more vulnerable families-that is, families with higher pre-pandemic levels of parent depression or lower levels of coparenting relationship quality. We conclude that targeted family prevention programming is able to promote healthy parent and child functioning during unforeseen future periods of acute stress. The long-term benefits of a universal approach to family support at the transition to parenthood indicate the need for greater investment in the dissemination of effective approaches.

Sibling conflict during COVID-19 in families with special educational needs and disabilities

Young people with special educational needs and disabilities (SENDs) and their families have been particularly hard hit by the COVID-19 pandemic. In this longitudinal study, sibling conflict in these families during and after the first lockdown in the United Kingdom was investigated. Online questionnaires were completed by 504 parents of young people with SENDs at four time points between 23 March 2020 and 10 October 2020 (over half completed the questionnaire at multiple time points). As lockdown progressed, young people with SENDs were more likely to be picked on or hurt by their siblings compared with earlier stages of the lockdown but there was no change in how frequently they harmed or picked on their siblings. After lockdown, both perpetration and victimization decreased but not to the same rates as the first month of lockdown. Young people with SENDs with severe or complex needs were somewhat protected from sibling conflict. Findings are discussed with reference to implications for support and planning for future pandemics.

Impact of Sibling Victimization on Child Internalizing Symptoms

The current study examined associations between sibling victimization and anxiety and depression symptoms while also considering peer victimization within time and six months later among elementary school-age youth. Both sibling and peer victimization were associated with depression symptoms within as well as across time when considered independently. However, when examined together, peer victimization was only uniquely associated with depression symptoms within time and sibling victimization was only uniquely associated with depression symptoms across time. Sibling and peer victimization were associated with anxiety symptoms within, but not across, time when examined independently, and no associations were evident when sibling and peer victimization were examined simultaneously. No interactive effects of sibling and peer victimization were evident for depression or anxiety symptoms, indicating unique rather than cumulative contributions. Findings suggest that the impact of sibling victimization on depression symptoms is more robust than effects of peer victimization over time.

The Impact of Formal School Entry on Children's Social Relationships with Parents, Siblings, and Friends

The normative transition to formal schooling confronts children with social challenges but also opportunities. Longitudinal research on how school entry impacts children's family and friend-ship relationships is scarce. This study investigated social relationship qualities with parents, siblings, and friends among 1110 children (49.9% female) from the prospective, population-based Bavarian Longitudinal Study at 6 years (before school entry) and 8 years using a forced-choice card-sorting task. Multivariate analyses of variance revealed significant effects of age (i.e., school entry) on social relationship qualities with mothers (Pillai's Trace (PT) = 0.28, F(9, 1101) = 47.73, p < 0.001), fathers (PT = 0.14, F(9, 1101) = 19.47, p < 0.001), siblings (PT = 0.27, F(9, 1101) = 46.14, p < 0.001), and friends (PT = 0.21, F(9, 1101) = 32.57, p < 0.001). On average, children reported higher levels of parental comfort after school entry. Companionable qualities increased in relationships with friends, whereas sibling relationships became more conflictual from preschool to early school age. Findings provide unique insights into how social relationships develop from preschool to early school age, supporting evidence of the growing importance of friends. Conflict was predominant and increasing in sibling relationships and should be considered more in future research.

Family Dynamics and Young Adults' Well-Being: The Mediating Role of Sibling Bullying

Although a common form of family violence, sibling bullying is often viewed as harmless by families and society. Consequently, it has not received as much attention in research compared with peer bullying or other types of family violence, such as interpartner violence, child abuse, and elder abuse. Considering that sibling relationships have lasting effects on children's development, this retrospective study focused on the antecedents and outcomes of sibling bullying. Grounded in family system theory and social learning theory, it explored whether sibling bullying during childhood and adolescence mediated the relationship between negative family dynamics (i.e., sibling rivalry, interparental hostility, and parental hostility) and young adults' well-being (i.e., sense of competence, internalized problems, self-esteem, and satisfaction with life). Data from 216 respondents were analyzed using structural equation modeling. Results revealed that young adults who reported higher levels of sibling rivalry and interparental hostility were more likely to be victims of sibling bullying. In turn, sibling bullying was associated with lower sense of competence, self-esteem, and life satisfaction, as well as more internalized problems. Parents' hostile behaviors toward their children were not associated with sibling bullying but were negatively associated with well-being in early adulthood. Our work underlines the importance of harmonious family dynamics and the need for sibling bullying to be taken more seriously by parents and family members. From a clinical point of view, our findings suggest that clinicians and human service workers should adopt a family-level approach when trying to reduce sibling bullying and its negative outcomes by educating parents about the interdependence of family relationships.

Aggression in Children Exposed to Intimate Partner Violence: A Comparison of Maternal, Sibling, and Observer Perspectives

The negative effects of exposure to intimate partner violence (IPV) on children have been well documented, including externalizing difficulties such as aggression. Although aggressive behavior is a common concern for these children, sibling aggression in children exposed to IPV has rarely been studied. Our purpose was to investigate similarities and differences in multiple informant reports of aggression by siblings exposed to IPV, and to examine how exposure to IPV was linked to these differing perspectives. Forty-seven sibling dyads and their mothers were recruited from the community. Aggression was assessed by observers, by mothers, and by the siblings themselves, whereas IPV was assessed by both maternal and child report. Informants had very differing views on aggression. Regression results indicated that children's reports of their own exposure to IPV accounted for significant variance in observed aggression between siblings, as well as in the maternal reports of aggression by both siblings. Aggression did not vary by sibling age, sex, or age spacing. Results were discussed within a risk and resilience framework.

Perceptions of Child Abuse as Manifested in Drawings and Narratives by Children and Adolescents

Child abuse is an underreported phenomenon despite its high global prevalence. This study investigated how child abuse is perceived by children and adolescents as manifested in their drawings and narratives, based on the well-established notion that drawings serve as a window into children's mental states. A sample of 97 Israeli children and adolescents aged 6-17 were asked to draw and narrate what child abuse meant to them. The drawings and narratives were coded quantitatively. The results indicated that participants did not perceive a distinction between abuse and violence and referred to them interchangeably. Almost half of the participants focused on emotional abuse. The most frequent type of abuse within the family was between parents and children, and the most frequent abuse outside the family was peer victimization. Most of the drawings were figurative and realistic and half of the drawings included words suggestive of the participants' attempts to be heard and fully understood. The vast majority of drawings did not include the figure of the artist, about a third of the drawings employed dissociative techniques (i.e., included positive objects, were unrelated to abuse, used words alone, or did not follow the instructions), and almost half of the narratives were dissociative or characterized by negative resolution, describing feelings such as sadness, humiliation, and loneliness. These findings suggest the emotional pain associated with the abuse or violence and the use of dissociative mechanisms to bypass the pain. The findings are discussed in light of the literature on children's disclosure.

Precursors of sibling bullying in middle childhood: Evidence from a UK-based longitudinal cohort study

BACKGROUND

There is increasing evidence that sibling bullying is associated with various social, emotional, and mental health difficulties. It is, however, unclear which factors predict sibling bullying in middle childhood and whether child-level individual differences make some children more susceptible to sibling bullying involvement.

OBJECTIVE

To investigate the precursors of sibling bullying in middle childhood in a UK based population sample.

PARTICIPANTS AND SETTING

Existing data from the prospective Millennium Cohort Study (N = 16,987) were used. Primary caregivers reported on precursors (child age 7 years or earlier) whilst children self-reported on sibling bullying (child age 11 years).

ANALYSIS

A series of multinomial logistic regression models were fitted. First, testing for crude associations between sibling bullying and the precursors individually. Culminating in a final model with the significant predictors from all of the previous models.

RESULTS

Structural family-level characteristics (e.g. birth order, ethnicity, and number of siblings) were found to be the strongest predictors of sibling bullying involvement followed by child-level individual differences (e.g. emotional dysregulation and sex). Parenting and parental characteristics (e.g. primary caregiver self-esteem and harsh parenting) predicted sibling bullying, but to a lesser extent.

CONCLUSIONS

These findings suggest that structural family characteristics and child-level individual differences are the most important risk factors for sibling bullying. If causality can be established in future research, they highlight the need for interventions to be two-pronged: aimed at parents, focusing on how to distribute their time and resources appropriately to all children, and the children themselves, targeting specific sibling bullying behaviors.

Sibling relationship pattern in the context of abuse and neglect: Results from a sample of adult siblings

BACKGROUND

Siblings take care of each other and provide comfort and support. However, the sibling relationship is often also characterized by conflict and rivalry. Accordingly, the sibling relationship can be described by four patterns: harmonious, hostile, distanced, and emotional-intense. The sibling relationship pattern (SRP) depends on the sibling constellation, but also to a large extent on the family environment. Surprisingly little research has focused on the effects of child maltreatment on the SRP.

OBJECTIVE

This paper investigates the impact of maltreatment on the SRP during childhood.

PARTICIPANTS AND SETTING

4568 adults provided information about their adverse experiences and SRP while growing up.

METHODS

Multinomial logistic regression analyses were calculated to identify unique predictors for different SRP.

RESULTS

The number of different types of maltreatment predicted a hostile SRP. A low number was associated with a harmonious SRP. Considering the specific influence of types of maltreatment, emotional abuse was predictive for the hostile and the emotional-intense SRP compared to the distanced and the harmonious SRP. Emotional neglect was predictive for either a distanced or a hostile SRP compared to a harmonious or emotional-intense SRP.

CONCLUSIONS

Child maltreatment influences the SRP in childhood. It increases the likelihood of a hostile and less harmonious SRP. However, for some types of maltreatment, especially in the absence of emotional abuse or emotional neglect, exceptions occur. Further research needs to untangle dynamics between siblings throughout childhood. For practice, the findings warrant the need for specific interventions to improve the sibling relationship in cases of child maltreatment.

Demographic and psychosocial profile of disruptive mood dysregulation disorder in Indian settings

AIMS

The aim of this study was to assess the demographic and psychosocial profile of the children with and without disruptive mood dysregulation disorder (DMDD) attending psychiatric and pediatric OPD and evaluation of the phenomenology of children diagnosed with DMDD.

MATERIALS AND METHODS

Children of 6-16 years attending the psychiatric outpatient department were screened by self-made peer-reviewed questionnaire and further underwent diagnostic evaluation using DSM 5 diagnostic criteria. Socioeconomic status (SES) was assessed using the Kuppuswamy scale. Affective Reactivity Index (ARI) was used to measure the severity of irritability. Overall behavioral problems were assessed on Conner's parent rating scale and impairment in functioning on the Children's Global Assessment of Functioning Scale.

RESULTS

A total of nine subjects were diagnosed with DMDD out of 500. The mean age of children with DMDD was higher than other children. DMDD children had better SES. Multiple psychosocial factors such as broken family, family history of psychiatric illness, and childhood adversities including sexual abuse were found to be a contributory factor. Those diagnosed with DMDD had significant conduct and learning problem along with moderate to severe irritability and a mean CGAS value of 50.66 which implies that children with DMDD had moderate impairment in functioning.

CONCLUSIONS

DMDD cases have male preponderance, urban background, and belong to upper and middle socioeconomic strata. Conduct problems, academic decline, hyperactivity, impulsivity, and mild degree of impairment in anxiety, along with moderate to severe irritability produce impairment in their overall functioning of these children.

Sibling Bullying in Middle Childhood is Associated with Psychosocial Difficulties in Early Adolescence: The Case of Individuals with Autism Spectrum Disorder

Sibling bullying is associated with various psychosocial difficulties. We investigated this in 231 individuals with Autism Spectrum Disorder (ASD) and 8180 without ASD between middle childhood (age 11 years) and early adolescence (age 14 years). On the whole, self-reported sibling bullying decreased from middle childhood to early adolescence. Despite this, individuals with ASD continued to report more sibling bullying as both perpetrator and victim in early adolescence than those without ASD. We found that self-report sibling bullying in middle childhood was associated with psychosocial difficulties in early adolescence. Moreover, individuals with ASD were more likely to report being bullied by both siblings and peers in middle childhood and this pattern of victimisation was associated with concurrent and longitudinal psychosocial difficulties.

Predictors of sibling victimization and associations with self-perception and relationship attachment in adolescence

Research has shown that sibling victimization may be as detrimental to adolescent outcomes as peer victimization. However, many questions remain unanswered with regard to potential protective parenting factors and consequences sibling victimization among adolescents. This study tested a mediation model of sibling victimization with parental monitoring, a positive parenting factor, as a predictor and parent and peer-adolescent attachment as mediated by adolescent self-perceptions as potential outcomes. A three path mediation from parental monitoring → sibling victimization → adolescent self-perceptions → peer/parent-adolescent attachment was also tested. Structural Equation Modeling revealed that parental monitoring was negatively associated with sibling victimization only for girls. Sibling victimization had negative direct and indirect effects on parent- and peer-adolescent attachment via adolescent self-perceptions of social competence and self-worth. Findings suggest that parental monitoring may be important in the prevention of sibling victimization and self-perceptions may be an important point of intervention adolescents experiencing sibling victimization.

Shorter birth intervals between siblings are associated with increased risk of parental divorce

Birth intervals are a crucial component of fertility behaviour and family planning. Short birth intervals are associated—although not necessarily causally—with negative health-related outcomes, but less is known about their associations with family functioning. Here, the associations between birth intervals and marital stability were investigated by Cox regression using a nationally representative, register-based sample of individuals with two (N = 42,481) or three (N = 22,514) children from contemporary Finland (observation period 1972–2009). Shorter interbirth intervals were associated with an increased risk of parental divorce over a ten-year follow-up. Individuals with birth intervals of up to 1.5 years had 24–49 per cent higher divorce risk compared to individuals whose children were born more than 4 years apart. The pattern was similar in all socioeconomic groups and among individuals with earlier and later entry to parenthood. Our results add to the growing body of research showing associations between short birth intervals and negative outcomes in health and family functioning.

Association Between Sub-types of Sibling Bullying and Mental Health Distress Among Chinese Children and Adolescents

Sibling bullying is a common phenomenon in childhood and adolescence worldwide and has a significant association with mental health distress. However, there have been few studies that have examined the associations between any specific sub-type of sibling bullying and depression as well as anxiety. Besides, the association between sibling bullying and psychological well-being was never explored among the Chinese population. The purpose of this cross-sectional study was to examine the associations between the number of sub-types of sibling bullying involvement and depression as well as anxiety among Chinese children and adolescents. Multi-stage stratified cluster sampling was used to recruit 5,926 participants aged 10 to 18 who had at least one sibling living in the household. Different sub-types of sibling bullying involvement were determined by using Olweus Bully/Victim Questionnaire (OBVQ). The nine-item Patient Health Questionnaire (PHQ-9) and the seven-item Generalized Anxiety Disorder Scale (GAD-7) were used to screen clinical ranges of major depression and generalized anxiety disorder, respectively. Of the participants, 1,235 (20.8%) were bullied by siblings, and 1,230 (20.8%) perpetrated bullying behavior against siblings over the past 6 months. After controlling potential confounders, adjusted model of logistic regression analyses indicated that all three sub-types of sibling victimization and perpetration were significantly associated with both depression and anxiety. There were linear associations between the number of sub-types of sibling bullying victimization and depression (adjusted OR = 1.49, 95% CI 1.32 to 1.68) as well as anxiety (adjusted OR = 1.68, 95% CI 1.48 to 1.90). Besides, linear trends were found between the number of sub-types of sibling bullying perpetration and depression (adjusted OR = 1.44, 95% CI 1.26 to 1.64) as well as anxiety (adjusted OR = 1.63, 95% CI 1.42 to 1.87). The findings underline dose-response relationships between the number of sub-types of sibling bullying involvement and mental health distress. Intervention programs should be conducted to focus on developing mental health status of those children and adolescents who are involved in multiple sub-types of sibling victimization or perpetration.

The Prevalence and Psychopathological Correlates of Sibling Bullying in Children with and without Autism Spectrum Disorder

Using data from a prospective population based study, the prevalence and psychopathological correlates of sibling bullying in children with and without autism spectrum disorder (ASD) were estimated. There were 475 children with ASD and 13,702 children without ASD aged 11 years. Children with ASD were more likely to be bullied by their siblings compared to those without ASD. They were also more likely than those without ASD to both bully and be bullied by their siblings, which was associated with lower prosocial skills as well as more internalizing and externalizing problems compared to those not involved in any sibling bullying. Interventions to improve social and emotional outcomes in children with ASD should focus on both the affected and the unaffected sibling.

Differentiating typical from atypical perpetration of sibling-directed aggression during the preschool years

BACKGROUND

Sibling aggression is common and often viewed as benign. Although sibling aggression can be harmful for the victims, it may also be a marker of clinical risk for the aggressor. We differentiated typical from atypical levels of perpetration of sibling-directed aggression among preschoolers, a developmental period in which aggression is a normative misbehavior, by (a) identifying how frequently aggressive behaviors targeted at a sibling must occur to be psychometrically atypical; (b) mapping the dimensional spectrum of sibling-directed aggression from typical, more commonly occurring behaviors to rarer, more atypical, actions; and (c) comparing the psychometric atypicality and typical-to-atypical spectrum of sibling-directed aggression and peer-directed aggression.

METHODS

Parents (N = 1,524) of 3- (39.2%), 4-(36.7%), and 5-(24.1%) year-olds (51.9% girls, 41.1% African-American, 31.9% Hispanic; 44.0% below the federal poverty line) completed the MAP-DB, which assesses how often children engage in aggressive behaviors. We used item-response theory (IRT) to address our objectives.

RESULTS

Most aggressive behaviors toward siblings were psychometrically atypical when they occurred 'most days' or more; in contrast, most behaviors targeted at peers were atypical when they occurred 'some days' or more. With siblings, relational aggression was more atypical than verbal aggression, whereas with peers, both relational and physical aggression were more atypical than verbal aggression. In both relationships, the most typical behavior was a verbally aggressive action. Results were broadly replicated in a second, independent sample.

CONCLUSIONS

These findings are a first step toward specifying features of sibling aggression that are markers of clinical risk and belie the notion that sibling aggression is inherently normative.

Parent- and Sibling-Directed Aggression in Children of Domestic Violence Victims

This study examines the nature of parent- and sibling-directed aggression and involvement in other victimization among children living with female caregivers in a domestic violence shelter. Caregivers were interviewed about their children's (N = 79; M_age = 9.0 years) parent- and sibling-directed aggression. Physical and verbal aggression and emotional blackmail were the most common forms of aggression against caregivers. Physical and verbal aggression were most common against siblings. No age or gender differences in aggression characteristics were found. A large minority of children displayed both parent- and sibling-directed aggression. Children exhibiting parent- or sibling-directed aggression were significantly more likely to be victimized. Findings highlight the importance of incorporating parent- and sibling-directed aggression into definitions of family violence and recognizing children can be victims and victimizers.

The Combination of Sibling Victimization and Parental Child Maltreatment on Mental Health Problems and Delinquency

This study examined how the combination of sibling victimization and parental child maltreatment is related to mental health problems and delinquency in childhood and adolescence. Co-occurrence, additive associations, and interactive associations of sibling victimization and parental child maltreatment were investigated using a sample of 2,053 children aged 5-17 years from the National Survey of Children's Exposure to Violence. The results provide primarily evidence for additive associations and only suggest some co-occurrence and interactive associations of sibling victimization and child maltreatment. Evidence for co-occurrence was weak and, when controlling for the other type of maltreatment, only found for neglect. Sibling victimization was related to more mental health problems and delinquency over and above the effect of child abuse and neglect. Moderation by sibling victimization depended on child age and was only found for the relation between both types of child maltreatment by parents and delinquency. For mental health, no interactive associations were found. These results highlight the unique and combined associations between sibling victimization on child development.

Aggression by Children Exposed to IPV: Exploring the Role of Child Depressive Symptoms, Trauma-Related Symptoms, & Warmth in Family Relationships

Multi-informant reports of aggression by siblings in families with and without a history of IPV were compared. Associations between aggressive behavior and child depressive and trauma-related symptoms, as well as maternal and sibling warmth were also explored. Mothers, observers and the siblings themselves reported on aggressive behaviour. Mothers reported on child trauma-related symptoms while children provided self-report on depressive symptoms and mother-child and sibling warmth. The frequency of observed aggression did not differ across groups on average, although more sibling dyads exposed to IPV engaged in aggression than those not exposed. Child reports of sibling aggression did not differ across groups but mothers reported significantly less aggressive behavior by children exposed to IPV than those not exposed. Regression results indicated that depressive and trauma-related symptoms were significant risk factors for aggression, while the role of mother-child and sibling warmth was more complex. Results were discussed within a developmental psychopathology framework.

Victimization by Siblings in Children with Disability or Weight Problems

OBJECTIVE

Children with a physical disability, psychological disorder, or of nonnormative weight are often targets of peer victimization. Sibling victimization, however, is more common than peer victimization, but rarely explored. We investigated linkages between sibling victimization and whether children had a physical disability, psychological disorder (i.e., internalizing disorder, attention deficit disorder/attention-deficit hyperactivity disorder), and were perceived by parents as being thinner than average or overweight. Also, we explored how the extent and kinds of sibling victimization experiences were related to these characteristics in childhood.

METHODS

A US probability sample of adult caregivers of a child aged 0 to 9 (N = 780; 50% women; mean age 4.58) in 2-child households who completed a telephone interview.

RESULTS

Controlling for other forms of maltreatment and individual and family characteristics, children with a physical disability and parent-perceived children who are thinner than average and children who are overweight experienced more sibling victimization. Children with an internalizing disorder experienced less sibling victimization. Sibling victimization did not differ for children with and without ADHD. Children perceived to be overweight by parents and children with a physical disability were at increased risk of experiencing more types of sibling victimization. Children with a physical disability had greater odds of being victims of property victimization by a sibling.

CONCLUSION

Children with a physical disability or perceived as different from average weight are at risk for sibling victimization. Using a nationally representative sample, this is the first study to highlight the importance of screening for sibling victimization in families of children with a disability and/or nonnormative weight status.

The State of Interventions for Sibling Conflict and Aggression: A Systematic Review

Sibling conflict and aggression is often a pervasive part of family life that parents want help managing and can have negative effects on children's well-being. The purpose of this systematic review is to evaluate current research regarding programs to reduce sibling conflict and aggression and promote positive sibling relationships. Online databases, reference lists, and Google Scholar were searched using key words and inclusion/exclusion criteria were applied. The search located five unique studies of programs focused on school-aged children. Heterogeneity of the studies precluded meta-analysis, but characteristics of the studies were systematically described. Three interventions were aimed at directly improving children's social skills and two interventions trained parents on mediation techniques to use during sibling conflicts. Overall, of the four studies that included assessment of children's social skills, the results were positive. Two of the three studies that evaluated sibling relationship quality demonstrated improved sibling interactions compared with the control group. With further research and evidentiary support, these programs have promise to modify sibling behaviors as part of current parenting education programs or as a stand-alone program to address sibling conflict and aggression.

Brief report: Physical health of adolescent perpetrators of sibling aggression

We describe adolescents' perpetration of sibling aggression and its link to physical health two years later. In-school surveys at Time 1 (N = 331) and Time 2 (two-years later, N = 283) were administered to adolescents (at Time 1, Mage = 15.71 years, SD = .63; 52% female) living in the United States querying about perpetration of aggression toward a sibling closest in age and perceived physical health. The majority of adolescents perpetrated aggression towards their sibling (74%). Adolescents who were part of brother-brother pairs reported the most aggression. Hierarchical regression analysis showed that perpetrating sibling aggression more often at Time 1 was predictive of lower physical health at Time 2 controlling for Time 1 physical health and demographic characteristics. Perpetration of aggression toward a sibling is common and has negative health consequences in late adolescence suggesting this issue should be targeted to improve adolescents' sibling dynamics and physical health.

Bullying in the family: sibling bullying

Sibling relationships have a substantial and lasting effect on children's development. Many siblings experience some occasional conflict, however, up to 40% are exposed to sibling bullying every week, a repeated and harmful form of intrafamilial aggression. We review evidence on the precursors, factors relating to peer bullying, and mental health consequences of sibling bullying. Parenting quality and behaviour are the intrafamilial factors most strongly associated with bullying between siblings. Sibling bullying increases the risk of being involved in peer bullying, and is independently associated with concurrent and early adult emotional problems, including distress, depression, and self-harm. The effects appear to be cumulative, with those children bullied by both siblings and peers having highly increased emotional problems compared with those bullied by siblings or peers only, probably because they have no safe place to escape from bullying. The link between sibling and peer bullying suggests interventions need to start at home. Health professionals should ask about sibling bullying and interventions are needed for families to prevent and reduce the health burden associated with sibling bullying.

Aggression can be contagious: Longitudinal associations between proactive aggression and reactive aggression among young twins

The present study examined sibling influence over reactive and proactive aggression in a sample of 452 same-sex twins (113 male dyads, 113 female dyads). Between and within siblings influence processes were examined as a function of relative levels of parental coercion and hostility to test the hypothesis that aggression contagion between twins occurs only among dyads who experience parental coerciveness. Teacher reports of reactive and proactive aggression were collected for each twin in kindergarten (M = 6.04 years; SD = 0.27) and in first grade (M = 7.08 years; SD = 0.27). Families were divided into relatively low, average, and relatively high parental coercion-hostility groups on the basis of maternal reports collected when the children were 5 years old. In families with relatively high levels of parental coercion-hostility, there was evidence of between-sibling influence, such that one twin's reactive aggression at age 6 predicted increases in the other twin's reactive aggression from ages 6 to 7, and one twin's proactive aggression at age 6 predicted increases in the other twin's proactive aggression from ages 6 to 7. There was also evidence of within-sibling influence such that a child's level of reactive aggression at age 6 predicted increases in the same child's proactive aggression at age 7, regardless of parental coercion-hostility. The findings provide new information about the etiology of reactive and proactive aggression and individual differences in their developmental interplay.

Aggression between siblings: Associations with the home environment and peer bullying

Sibling aggression is a common form of intra-familial aggression, yet has been largely neglected by research. Using an inclusive measure of sibling aggression, this study investigated, firstly, prevalence of sibling aggression and associations with family and household characteristics, and secondly, the relationship between sibling aggression and peer bullying. Participants were 4,237 adolescents from Wave 1 of Understanding Society. Four types of sibling aggression were measured: physical, verbal, stealing and teasing, and combined into composite measures of victimization and perpetration. Regression analysis identified associations with demographic characteristics, family and sibling composition, parent-child relationships and socioeconomic status and explored the link between sibling aggression and involvement in peer bullying. Using a broad definition, sibling aggression was found to be widespread, with 46% of all participants being victimized and 36% perpetrating aggression. Household and family characteristics, including a large family size, male siblings, and financial difficulties were associated with greater rates of sibling aggression. Parenting behavior showed the strongest relationship: harsh parenting increased the risk of sibling aggression while positive parenting protected against it. Sibling aggression was also homotypically related to involvement in peer bullying. Victimization by siblings significantly increased the odds of being a victim of peer bullying, and perpetrators of sibling aggression were more likely to be both peer bullies and bully-victims. Considering the adverse effects of sibling aggression on physical and mental health, the study provides pointers for efforts to reduce the risk of sibling aggression. Furthermore, the link with peer bullying suggests that school anti-bullying efforts should also take account of children's sibling relationships. Aggr.

Sibling and peer victimization in childhood and adolescence

This study examined how victimizations by either a sibling or peer are linked to each other and to mental health in childhood and adolescence. The data were from the National Survey of Children's Exposure to Violence which includes a sample of children aged 3-9 (N=1,536) and adolescents aged 10-17 (N=1,523) gathered through telephone interviews. An adult caregiver (usually a parent) provided the information for children while self-reports were employed for adolescents. Fifteen percent of each age group reported victimization by both a sibling and peer. Victimization by a sibling alone was more common in childhood than adolescence. Victimization by a sibling was predictive of peer victimization. Children and adolescents victimized by both a sibling and peer reported the greatest mental distress. This work establishes that for some children and adolescents, victimization at the hands of other juveniles happens both at home and school. Programs should consider the role of siblings and target parents and siblings to encourage the development and maintenance of constructive sibling interactions.

Childhood sibling and peer relationships of perpetrators of child sexual abuse

Maltreatment by parents inhibits a child's ability to form relationships with other children. Given that many sex offenders experienced parental abuse, investigation of their relationships with siblings and peers could provide new directions for early childhood interventions. Interview transcripts of 23 community-dwelling perpetrators of sexual abuse against children were examined in this secondary data analysis. Ages of participants ranged from 20s to 70s, and education ranged from GED to PhD. Phenomenological analysis revealed that neither sibling nor peer relationships adequately promoted participants' capacity for developing and maintaining healthy relationships in adulthood. Until societal preventive actions and early clinical interventions are more successful, the crime of child sexual abuse will continue to be far too common.

Association of sibling aggression with child and adolescent mental health

OBJECTIVE

Sibling aggression is common but often dismissed as benign. We examine whether being a victim of various forms of sibling aggression is associated with children's and adolescents' mental health distress. We also contrast the consequences of sibling versus peer aggression for children's and adolescents' mental health.

METHODS

We analyzed a national probability sample (n = 3599) that included telephone interviews about past year victimizations conducted with youth aged 10 to 17 or an adult caregiver concerning children aged 0 to 9.

RESULTS

Children ages 0 to 9 and youth ages 10 to 17 who experienced sibling aggression in the past year (ie, psychological, property, mild or severe physical assault), reported greater mental health distress. Children ages 0 to 9 showed greater mental health distress than did youth aged 10 to 17 in the case of mild physical assault, but they did not differ for the other types of sibling aggression. Comparison of sibling versus peer aggression generally showed that sibling and peer aggression independently and uniquely predicted worsened mental health.

CONCLUSIONS

The possible importance of sibling aggression for children's and adolescents' mental health should not be dismissed. The mobilization to prevent and stop peer victimization and bullying should expand to encompass sibling aggression as well.
