Sibling and School Bullying Victimization and Its Relation With Children's Subjective Well-Being in Indonesia: The Protective Role of Family and School Climate.

Studies on the influence of family and school climates on the relationships between sibling and school bullying victimization and children's subjective well-being (SWB) in Indonesia are still scarce. The aims of this study are to investigate family and school climates as protective factors for children from the negative consequences of bullying by siblings or other children in school on SWB. The study used the third-wave data of the Children's Worlds survey that was collected in Indonesia in October 2017. Participants of the study were children aged 10 and 12 years old (N = 15,604; 49.8% girls, 50.2% boys, Mean age = 10.55; SD = 1.17). There are four questionnaires used in the study: five items measure bullying at home and at school, the Children's Worlds Subjective Well-Being Scale, six items measure family climate, and four items measure school climate. Data were analyzed using R and the lavaan library for multilevel structural equation modeling, using full information maximum likelihood (FIML) for missing data and robust maximum likelihood (ML) estimation. Results showed that children who experienced bullying incidents, both at home by siblings and at school, predicted lower levels of SWB. School climate and family climate predicted higher levels of SWB. Results also showed that school bullying interacted significantly with school climate, while sibling bullying interacted significantly with family climate. Schools with students that reported more positive levels of family climate also reported higher levels of SWB. Students from public schools reported higher levels of SWB, which is unexpected.

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.

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.

A longitudinal study of sibling bullying and mental health in autistic adolescents: The role of self-esteem.

Sibling bullying is associated with poor mental health in autistic adolescents. The reasons for this remain unknown. In the current study, we attempted to replicate the existing findings on the direct associations between sibling bullying and mental health in autistic adolescents and expand knowledge by focusing on the indirect associations through self-esteem. We made use of existing data from the Millennium Cohort Study, a nationally representative UK-based birth cohort study. We fitted a mediation model to longitudinal data from a sample of 416 autistic adolescents aged 11, 14, and 17 years old who had at least one sibling. We found that sibling bullying was prevalent in the lives of autistic adolescents, especially in those who were late-diagnosed, had a shared bedroom, and lived in a low-income household. Additionally, increased sibling bullying in early adolescence was a significant predictor of reduced self-esteem in mid-adolescence; in turn, reduced self-esteem predicted poorer mental health and wellbeing in late adolescence. Our findings indicate that sibling bullying in early adolescence may indirectly lead to poorer mental health and wellbeing in late adolescence through a reduction in self-esteem in mid-adolescence in autistic adolescents. We discuss the implications of these findings further.

Factors affecting sibling bullying and its association with self-esteem and depression in middle school students.

Sibling bullying is an unwanted aggressive behavior of a sibling that is associated with peer bullying and emotional problems. However, the prevalence of sibling bullying, the factors that affect this condition, and its impact on depression and self-esteem are understudied, especially in Thailand. This study aims to examine the prevalence of sibling bullying, factors that affect sibling bullying, and its association with self-esteem and depression during the pandemic. From January to February 2022, a cross-sectional study was conducted in grades 7-9 (age 12-15 years) who had at least one sibling. Demographic characteristics, sibling bullying, self-esteem, and depression were collected using the revised Olweus bully/victim questionnaire, the Rosenberg self-esteem scale, and Patient Health Questionnaire-9, respectively. Binary logistic regression was analyzed to determine associations between sibling bullying and outcomes. Of 352 participants (30.4% female), 92 (26.1%) were victims and 49 (13.9%) were bullies of sibling bullying in the previous 6 months. Factors associated with an increased risk of being victims included female (OR = 2.46; 95%CI 1.34-4.53), peer victimization (OR = 12.99; 95%CI 5.27-32.04), domestic violence (OR = 4.48; 95%CI 1.68-11.95), and perpetrating sibling bullying (OR = 9.81; 95%CI 4.62-20.81). Factors associated with an increased risk of depression were female (OR = 2.59; 95%CI 1.57-4.26), sibling bullying victimization (OR = 2.08; 95%CI 1.22-3.56), physical abuse (OR = 9.50, 95%CI 1.13-79.71) and domestic violence (OR = 3.44; 95%CI 1.40-8.45).  Conclusion: Sibling bullying was not uncommon in Thai young adolescents and was associated with female, peer bullying, domestic violence, and depression. Such associations should be identified early so preventive measures and management could be properly implemented. What is Known: • Sibling bullying increases the risk for engaging in peer bullying, aggressive behaviors, violence, and emotional difficulties during life course trajectories. • Victims of sibling bullying are at increased risk of depression, anxiety, mental distress, self-harm, and decreased well-being. What is New: • The rate of sibling bullying in Thai middle school students, even during the pandemic, was comparable to previous studies of different cultural backgrounds without the pandemic. • Victims of sibling bullying were associated with female sex, peer victimization, domestic violence, perpetrating sibling bullying, and depression. Perpetrating sibling bullying was also associated with bullies in cyberbullying.

Sibling Bullying, School Bullying, and Children's Subjective Well-Being Before and During the COVID-19 Pandemic in Indonesia.

The aims of this study are threefold. The first aim is to examine the prevalence of sibling and school bullying before and during the COVID-19 pandemic in Indonesia. The second aim is to investigate the subjective well-being (SWB) of children who were bullied or never bullied before and during COVID-19. The third aim is to investigate factors associated with sibling and school bullying before and during the COVID-19 pandemic. This study uses two separate cross-sectional datasets from the Children's Worlds survey in Indonesia. Data in Study 1 were collected in October 2017 (N = 12,794; 48.2% boys; 51.8% girls, mean age = 10.56), while data in Study 2 were collected from July to September 2021 (N = 2,222; 46.1% boys; 53.9% girls; mean age = 10.77). Five items were used to measure sibling and school bullying. The five-item version of the Children's Worlds Subjective Well-Being Scale (CW-SWBS5) was used as the SWB indicator. Three groups of independent variables (family, friends and school climate) were analysed using linear regression to investigate the contribution of each variable to sibling and school bullying. Results show that the prevalence of sibling bullying during the COVID-19 pandemic is higher than before the pandemic, while the frequency of school bullying incidents during COVID-19 is lower than before COVID-19. SWB scores of children during COVID-19 are lower than SWB scores of children before the COVID-19 pandemic, both for bullied or never-bullied children. The fact that children report that parents listen to them and take what they say into account is positively associated with a lower frequency of being bullied at home before and during COVID-19 and being bullied at school only during the pandemic. Although samples are not strictly comparable, the SWB indicators used in both studies showed sensitivity to the changes in children's lives in previous studies. Therefore, the SWB indicators are supposed to be sensitive to changes associated with children's new everyday life COVID-19 has implied.

The Associations between Sibling Victimization, Sibling Bullying, Parental Acceptance-Rejection, and School Bullying.

Bullying has been identified as the most common form of aggression experienced by school-age youth. However, it is still unclear about the family's influence on school bullying. Therefore, the current study aimed to explore the associations between sibling bullying and school bullying, sibling victimization and school victimization, and parental acceptance-rejection and school bullying victimization. The study was cross-sectional and conducted on a sample of students aged between 11 and 20 years recruited from middle schools in Algeria. The study used a survey adopted from the scale of Sibling Bullying, Student Survey of Bullying Behavior-Revised 2, and the Survey of parental acceptance-rejection in collecting the data. The model's results assessing the association between sibling bullying and school bullying demonstrated that the effect of sibling physical and sibling verbal victims on school victimization was statistically significant. Despite the non-significant effect of sibling emotional victims on school victimization, the effect of sibling physical and sibling verbal bullying on school bullying was statistically significant. However, the effect of sibling emotional bullying on school bullying was not statistically significant. The direct effect of parental acceptance on school victimization was not statistically significant, whereas the effect of parental rejection on school victimization was statistically significant. The direct effect of parental acceptance on school bullying was not statistically significant, while the effect of parental rejection on school bullying was statistically significant. Based on the results, this study provides insights into the understanding of how the family and siblings contribute to school bullying. In particular, sibling victimization, sibling bullying, and parental acceptance-rejection are predictive factors of school bullying among adolescents. Future research should take into account factors based on family to explore the risks of school bullying.

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.

Sibling bullying among Vietnamese children: the relation with peer bullying and subjective well-being.

BACKGROUND: Siblings play an important role in a child's life. However, many children often experience sibling bullying. This study investigates differences in sibling victimization by sex, age, a parent's absence from the home due to employment, or a child's privacy and the relationship between sibling victimization, peer victimization, and the child's well-being. PARTICIPANTS AND PROCEDURE: Participants were Vietnamese children participating in the third wave of the International Survey of Children's Well-Being. The study included 1537 children (811 boys and 726 girls) attending public schools, age 10-14 years (M = 11.29, SD = 1.15). RESULTS: The results show that over half of children with siblings in this study reported being victimized by a sibling. Younger children were bullied more often than older children. Children whose father worked away from home reported an increase in bullying behavior from their siblings. Children sharing a room with siblings reported being bullied more by siblings. CONCLUSIONS: The results indicated a positive correlation between sibling victimization and peer victimization and a negative relationship between being bullied and a child's subjective well-being.

Family Bullying in Childhood: Consequences for Young Adults.

This study investigated childhood family bullying and explored any ongoing impacts for young adults. Research has demonstrated that peer bullying leads to contemporaneous poor consequences and some inquiries establish adverse effects of peer bullying lasting into adult life. However, family bullying is much less studied and the effects are not well understood. While there is urgency to intervene in peer bullying, this does not extend to family bullying. The aims of this inquiry were to discover what types of childhood bullying occur in families, any ongoing consequences, and how young adults define bullying. The study was a retrospective qualitative inquiry with a purposive sample. There were 43 participants: the majority were female, mean age 24.3 years, and 27% represented minorities. A qualitative description approach based in naturalistic inquiry was employed for data analysis to understand the lived experiences of young adults. NVivo 11 was used for data storage and analysis. A multi-phase coding process was utilized along with thematic analysis. Types of family bullying and participants' definitions of bullying were generated. Thematic analysis revealed lasting consequences in (a) low self-esteem and shame, (b) eating disorders, and (c) behavioral issues and relationship problems. Outcomes indicate the importance of further research on childhood family bullying as it affects young adult life and the need for researchers as well as practitioners to understand its lifelong impact.

The association between sibling bullying and psychotic-like experiences among children age 11-16 years in China.

BACKGROUND: Few studies exist on sibling bullying or even sibling aggression more generally in the past 30 years. Studies of sibling bullying have shown that sibling bullying may associate with depression, anxiety, self-harm, suicide ideation in early adulthood. Nevertheless, few studies have explored the relationship between sibling victimization types and the occurrence of psychosis, not to mention that psychotic-like experiences (PLEs) always occur before psychotic disorders. Therefore, the current study aims to examine the association between sibling bullying and PLEs among children age 11-16 years in China. METHOD: This is a cross-sectional study which included 3231 students from eight junior middle schools in three cities of Hunan Province, China. Frequency and types of sibling bullying was assessed with Sibling Bullying Questionnaire and PLEs was assessed with Community Assessment Psychic Experiences-42. RESULTS: The percentage of sibling bullying were 12.9% for victimization and 10.8% for perpetration. Sibling bullying plays as an independent influence factor for all subtypes of PLEs, and verbal victimization was the most important risk factor in developing different subtypes of PLEs followed by physical victimization and verbal perpetration. CONCLUSION: The current study found that sibling bullying is associated with PLEs. Intervention programs should be conducted to focus on those children and adolescents who are involved in multiple types of sibling victimization or perpetration.

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.

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.

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.

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.

Sibling bullying perpetration: associations with gender, grade, peer perpetration, trait anger, and moral disengagement.

This study investigated bullying among siblings in both traditional and cyber forms, and the associations of gender, grade, peer bullying perpetration, trait anger, and moral disengagement. The participants were 455 children in Grades 5 to 12 (262 girls and 177 boys with 16 unknown gender) who had a sibling. As the number of siblings who only bullied by technology was low, these associations were not able to be calculated. However, the findings showed that the percentage of sibling traditional bullying perpetration (31.6%) was higher than peer bullying perpetration (9.8%). Sibling bullies reported engaging in complex behaviors of perpetration and victimization in both the physical and in cyber settings, although the number was small. Gender, trait anger, moral disengagement, and bullying peers at school (but not grade) were all significantly associated with sibling traditional bullying perpetration. The implications of the findings are discussed for bullying intervention and prevention programs to understand childhood bullying in diverse contexts.
