Parental non-involvement strategy for handling sibling conflict on social avoidance in migrant children: Chain mediation of sibling conflict and parent-child conflict.

In the process of urbanization, the social adaptation of migrant children has become an important issue in their development. This study adopts family systems theory and ecological systems theory to examine the effects of parental non-involvement strategies in handling sibling conflict on migrant children's social avoidance. It also investigates the mediating role of sibling conflict and parent-child conflict. The results of the study, reported by parents of 253 mobile children with siblings, suggest that parental strategies of not intervening in sibling conflict are an important factor influencing the development of social avoidance in mobile children. The Parental strategy of not intervening in sibling conflict had an effect on migrant children's social avoidance through the separate mediating effect of parent-child conflict, and also through the chained mediating effect of sibling conflict and parent-child conflict. The study also found that the separate mediating effect of sibling conflict was not significant. This study contributes to the research on the relationship between parental non-intervention in sibling conflict and migrant children's social avoidance. It also highlights the impact of sibling conflict and parent-child conflict on migrant children's social avoidance by establishing and validating a comprehensive research model. The results of the study can help parents establish close parent-child relationships for migrant children and provide scientific guidance for children to develop positive sibling relationships. This, in turn, can assist migrant children in better adapting to a new social environment.

Effects of a behavioral intervention with foster families: A randomized controlled trial.

BACKGROUND: The health and well-being of children in foster care are of high concern. A resource with which to disrupt maladaptation and promote healing are positive relationships among children and caregivers within the foster home. The research question was: Can an online intervention improve family hardiness and sibling relationships within foster care families? OBJECTIVES: To: (1) establish feasibility and acceptability of an online behavioral intervention within the foster family, (2) explore the effects of the intervention on relational quality outcomes, and (3) decompose the mechanisms driving improved family hardiness through mediation analysis. PARTICIPANTS AND SETTING: 95 currently fostering families across the US, participated in a 4-week, online, self-paced, behavioral intervention with an emphasis on the relationship between children residing in the home. METHODS: We employed a randomized control trial design with multiple regression analysis. Stress and relational quality outcomes were measured through psychometrically validated questionnaires on family hardiness, preparedness, and sibling relationships. RESULTS: Significant increase in family hardiness (Cohen's d = 0.97, p < 0.001) were found compared to the control group. Measures of a positive sibling relationship score increased significantly in the intervention group (d = 0.76, p < 0.002), mediating 32 % of the total effect in hardiness score. Sibling relationship served as a mediator for increasing indicators of family hardiness. CONCLUSIONS: Providing families the sibling-inclusive intervention caused an increase in positive indicators of sibling relationship and overall family hardiness. Researchers should consider the implications of supporting foster siblings and the affects their inclusion may have on outcomes for children in foster care.

Siblings at home: Moderating influence of sibling presence and composition on the relation between problem behaviors and Theory of Mind in early childhood.

Despite the prevalence of internalizing and externalizing difficulties in children, the impact of these problem behaviors on the development of important social cognitive skills, such as Theory of Mind (ToM), is not well-understood. Indeed, many studies that have explored relations between problem behaviors and ToM report inconsistent findings. A possible reason for these disparities may be a lack of accounting for social protective factors within the home, such as the presence and number of siblings. Here, we explored the moderating influence of sibling presence and number on the relation between problem behaviors (i.e., internalizing and externalizing) and ToM. A total of 184 children (88 boys; Mage = 64.6 months, SD = 10.39) completed six well-validated ToM tasks while mothers reported on their children's externalizing and internalizing behaviors. Children who had siblings living in the same home exhibited higher ToM than children without siblings. In addition, both sibling presence and number of siblings moderated the relation between children's externalizing behaviors and ToM, such that in children without siblings externalizing behaviors were negatively associated with ToM. In contrast, children with siblings had similar ToM regardless of externalizing behaviors. As well, children with relatively fewer siblings and higher externalizing behaviors displayed lower ToM than children with relatively more siblings and higher externalizing behaviors. We did not detect a moderating effect of sibling presence or number on the relation between internalizing behaviors and ToM. These findings provide support for siblings' protective utility within the context of children's social cognition.

Sibling relatedness and pubertal development in girls and boys: A population-based cohort study.

PURPOSE: To investigate the association between sibling relatedness and pubertal development in girls and boys. METHODS: This cohort study consisted of 10,657 children from the Puberty Cohort, Denmark. Information on sibling relatedness was obtained by self-report. Information on pubertal markers was obtained half yearly from age 11 and throughout puberty. Mean age difference at attaining pubertal markers was estimated using interval-censored regression models according to sibling relatedness (full, half and/or step siblings; half and/or step siblings; no siblings; relative to full siblings). RESULTS: Girls with both full, half and/or step siblings (-1.2 (CI 95 %: -2.5; 0.1) months), only half- and/or stepsiblings (-2.2 (CI 95 %: -3.7; -0.7) months), and no siblings (-5.5 (CI 95 %: -8.5; -2.5) months) entered puberty earlier than girls with full siblings. Boys with full, half and/or step siblings (-1.4 (CI 95 %: -2.7; -0.1) months), only half and/or step siblings (-1.2 (CI 95 %: -3.0; 0.6) months), and no siblings (-4.5 (CI 95 %: -8.8; -0.3) months) entered puberty earlier than boys with full siblings. CONCLUSIONS: Children with sibling relatedness other than full siblings entered puberty earlier than their peers with full siblings even after adjustment for parental cohabitation status, childhood body mass index and childhood internalizing and externalizing symptoms.

Sibling relational aggression: Developmental change and associations with family relationships across adolescence.

Sibling relational aggression is an understudied social and family process that is of developmental significance in adolescence, a period of interpersonal relationship development. This study examined developmental change in sibling relational aggression across adolescence and used multilevel actor-partner independence models to test its longitudinal associations with mother-adolescent, father-adolescent, and sibling relationship qualities. Participants were 196 adolescent (firstborn-secondborn) sibling pairs from predominantly White families who averaged 16.47 years (SD = .80) and 13.88 years (SD = 1.15) of age, respectively, at baseline. Data were collected separately from each sibling during home interviews at three timepoints, each spaced a year apart. Longitudinal growth modeling revealed declines in sibling relational aggression from early to late adolescence. Findings from longitudinal multilevel actor-partner independence models revealed a negative within-person (WP) effect of father-adolescent intimacy and a positive WP effect of father-adolescent conflict on sibling relational aggression: On occasions when adolescents reported lower intimacy or more conflict with their fathers than usual (compared to individuals' own cross-time averages), adolescents reported experiencing more sibling relational aggression than usual. A between-person (BP) effect of mother-adolescent conflict also indicated that the cross-time average of mother-adolescent conflict was linked positively to the cross-time average of sibling relationship aggression. Primarily at the WP level, associations also emerged between lower sibling intimacy and higher sibling conflict and sibling relational aggression. For relationships with fathers and siblings, some effects were moderated by sibling structural characteristics. Discussion highlights the interplay of family relationship dynamics, including gender dynamics, and sibling relational aggression in adolescence.

Sibling Support for Transgender and Gender-Diverse Youth: A Scoping Review.

Sibling support for transgender and nonbinary (TNB) youth has the potential to improve TNB youths' mental health. A scoping review was conducted to map the knowledge of TNB youths' sibling relationships to create a foundation for the development of sibling-based support interventions for TNB youth. Nine included articles covered two areas: TNB youths' perceptions of sibling support (n = 5) and cisgender siblings' lived experience with a TNB sibling (n = 4). Siblings were perceived to support TNB youth, and their support was associated with less depression, suicidal ideation, and externalizing problems. Siblings of TNB youth lacked knowledge of TNB identities and support for their own understanding and acceptance. Siblings may experience unique stressors around their TNB sibling's changing gender identity. Overall, having a TNB sibling was perceived as a positive experience. None of the studies included intervention with or for siblings of TNB youth. Sibling support can be helpful for TNB youths' mental health. However, cisgender siblings' unique needs are rarely addressed. Providing cisgender siblings with knowledge of TNB identity, a place to process fears and concerns, and skills to navigate situations that may arise in relation to their sibling's gender, has the potential to benefit both siblings.

Emerging adults' emotions toward their siblings with down syndrome.

BACKGROUND: Typically-developing siblings of individuals with Down Syndrome often experience complex emotions towards their sibling. This study explored how social support, personal resources (optimism, sense of coherence [SOC]), and individual variables (sex, religious affiliation, siblings' functionality) may impact emerging adult siblings' emotions toward their sibling with Down Syndrome. METHODS: Participants were 292 siblings of individuals with DS ranging in age from 18-27 (M=21.54, SD=2.50). Participants completed self-report questionnaires exploring optimism, SOC, support, and acceptance. RESULTS: Higher levels of support and optimism were positively associated with positive emotions, and higher SOC with lower levels of negative emotions. Siblings' functionality and religious affiliation interacted with variables to predict emotions. CONCLUSIONS: This study contributes to a greater understanding of how emotions may play a role in sibling relations during the emerging adulthood stage. It also provides unique insight into how religious affiliation may be associated with more positive outcomes for siblings.

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.

"Filling in the gap": A qualitative case study about identity construction of siblings of youth with a neurodisability.

INTRODUCTION: In families of children with a neurodisability, siblings have unique experiences that can shape their identity. There is limited information about the developmental process of how siblings form their identity. This study aims to understand the identity construction of young siblings who have a sibling with a neurodisability. METHODS: As part of a patient-oriented research program, we engaged with our Sibling Youth Advisory Council in Canada. In this qualitative case study, data from semi-structured interviews augmented by photo elicitation and graphic elicitation of relational maps were analyzed using reflexive thematic analysis. RESULTS: Nineteen sibling participants (median age = 19 years, range = 14-33 years) reflected on the uniqueness of their role during childhood. During adolescence and emerging adulthood, they became closer with their sibling with a neurodisability and increased communication with their parents about how to care for their sibling with a neurodisability. These experiences influenced how they explored and began to reconcile their sibling identity with their professional and social identities. CONCLUSION: Siblings of youth with a neurodisability discover their unique identity and require support in this developmental process. Future interventions could evaluate how supports for siblings can have an impact on the positive development of their identity.

Sibling adjustment to diabetes and educational needs: A literature review.

ABSTRACT: As cases of type 1 diabetes mellitus (T1DM) increase, so do their impact on sibling relationships. This literature review of four databases from 2010 to 2024 discusses findings from five studies and the themes that emerged: education needs and family functioning. Improvements in family-centered care and education are needed for siblings of children with T1DM.

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.

Using emulated clinical trials to investigate the risk of being diagnosed with psychiatric ill health following the cancer diagnosis of a sibling.

BACKGROUND: The sibling bond is often the longest relationship in an individual's life, spanning both good and bad times. Focusing on the latter, we investigated whether a cancer diagnosis in one adult sibling is predictive of psychiatric illness in the other, and if any such effect differs according the 'sociodemographic closeness' between the siblings in terms of sex, age, education, marital status and residence. METHODS: We used hospital records to identify psychiatric diagnoses (2005-2019) in a Swedish total-population cohort born in 1953, and cancer diagnoses (2005-2017) in their full siblings. By means of emulated clinical trials, the cohort member's risk of a diagnosis within two years following a first exposure (or non-exposure) to a sibling's cancer was analyzed through Cox regression. RESULTS: Exposed cohort members had a higher risk of psychiatric diagnosis than unexposed (HR = 1.15; CI: 1.08-1.23), with men displaying a higher risk (1.19; CI: 1.09-1.31) than women (HR = 1.11; CI: 1.01-1.22). Sub-analyses of the exposed group showed that women with a cancer-stricken sister had a higher risk of adverse psychiatric outcomes (HR = 1.31; CI: 1.07-1.61) than women with a cancer-stricken brother. Furthermore, unmarried cohort members ran a higher risk, both when the cancer-stricken sibling was married (HR = 2.03; CI: 1.67-2.46) and unmarried (HR = 2.61; CI: 2.16-3.15), than in cases where both siblings were married. No corresponding difference were detected for 'closeness' in age, education and residence. CONCLUSIONS: In line with theories of linked lives, our findings suggest that negative events in one sibling's life tend to 'spill over' on the other sibling's wellbeing, at least during the 15-year-long period leading up to retirement age.

Sibling comparisons, sibling relationship quality, and perceived sport competence in young athletes.

Siblings are overlooked, yet potentially meaningful social agents in youth sport. To better understand the role of siblings in youth sport, we examined the association between sibling sport-referenced comparisons, relationship qualities, and perceived sport competence. The tendency to make sibling comparisons was expected to be positively related to sport competence perceptions and this association was further expected to be moderated by markers of sibling relationship quality. Participants were 47 sport-involved sibling dyads that included older siblings (25 female, 22 male, Mage = 10.94 ± 1.49 yrs) who were predominately first-born children (83%) and their younger siblings (23 female, 24 male participants, Mage = 8.45 ± 1.01 yrs) who were mostly second-born children (79%). Participants completed established assessments of comparison tendency, sibling relationship qualities, and sport competence perceptions. Analyses revealed a three-way interaction between birth position (younger or older sibling), tendency to compare, and sibling warmth predicting sport competence (p < .05). Younger siblings with a greater tendency to make sibling comparisons and higher warmth perceptions reported higher sport competence perceptions. The findings suggest that sibling-based comparisons and relational warmth may be salient for younger siblings in gauging their competence, whereas older siblings utilize alternative sources of competence information.

'People don't realise how much their past experiences affect them in adulthood': A qualitative study of adult siblings' experiences of growing-up with a sister/brother with a childhood life-limiting condition and their perceived support needs.

BACKGROUND: There is a lack of research about the experiences and impact of having a sibling with a life-limiting condition. Studies focus on the sibling experience during childhood but the experience and impact during adulthood is unknown despite the increased life-expectancy of children with life-limiting conditions. AIM: To explore adult siblings' perspectives on the experience of having a sister/brother with a childhood life-limiting condition and to identify their perceived needs and preferences for support. DESIGN: A qualitative exploratory study design with data generated by semi-structured interviews and analysed using reflexive thematic analysis, underpinned by interpretivism. SETTING/PARTICIPANTS: Twenty-two siblings (17-42 years old) were recruited via a children's hospice in England. RESULTS: The experience of having a sibling with a life-limiting condition changes over time in response to how understandings of the meaning of a life-limiting condition develop and changing roles/relationships with parents and siblings. These experiences have an enduring impact on adult sibling's mental health which is compounded by their unmet (and sometimes unrecognised) support needs in adolescence and adulthood. Siblings described the importance of support continuing into adulthood with a focus on the provision of psychotherapy and peer support. CONCLUSIONS: Having a sister/brother with a childhood life-limiting condition appeared to have a significant and ongoing impact on adult siblings but their support needs, particularly for psychotherapy and peer support, are overlooked. The findings highlight the importance of ensuring siblings are included in family assessments and that family-based interventions are developed to promote sibling-parent relationships.

What challenges do siblings of children with chronic disorders express to their parents? A thematic analysis of 73 sibling-parent dialogues.

PURPOSE: The study explored challenges experienced by siblings of children with chronic disorders, as expressed by siblings in parent-child dialogues. DESIGN AND METHODS: Seventy-three parent-child dialogues (M duration = 28.6 min) were analyzed using qualitative thematic analysis. The dialogues took place within the SIBS group intervention for siblings and parents of children with chronic disorders. The siblings (aged 8 to 14 years) had brothers and sisters with autism spectrum disorders, ADHD, rare disorders, cerebral palsy, or severe mental health disorders. The data are from session 5 in the SIBS intervention, in which the siblings are to express their wishes about family-related challenges (e.g., desired changes) to their parents. The parents are encouraged to listen, explore, and validate the child's perspective before discussing solutions. RESULTS: Most of the family-oriented challenges the siblings expressed were related to the diagnosis of the brother or sister with a disorder. Four main themes were identified: (1) Family life (e.g., limitations in family activities); (2) The diagnosis (e.g., concerns about the future); (3) Violence; and (4) Important relationships. CONCLUSION: The siblings experienced challenges and difficult emotions in interactional processes in which the diagnosis affected family life and relationships. The study adds a new dimension to the field by identifying siblings' expressed challenges based on parent-child dialogues. PRACTICE IMPLICATIONS: Identified themes can guide how parents should meet and address siblings' needs, how health care providers inform and support parents in doing so, and emphasize the relevance of interventions targeting family-level risk and resilience factors.

Experiences of cisgender youth with a transgender and/or nonbinary sibling.

While recent research has begun to address the effects of family support on transgender and/or nonbinary youth (TNY), almost no studies have directly examined how cisgender siblings in families with TNY navigate their sibling's gender disclosure and affirmation within both their families and their larger communities. We conducted an exploratory secondary analysis of in-person, semi-structured interviews with 15 adolescent and young adult siblings (age 13-24 years) of TNY from the northeastern United States from the baseline wave of the community-based, longitudinal, mixed methods Trans Teen and Family Narratives Project. Interview transcripts were analyzed using immersion/crystallization and template organizing approaches. Analyses yielded three main themes: gender-related beliefs and knowledge, peri- and post-disclosure family dynamics, and assessing responses to their sibling. Subthemes included anticipation of their sibling's TN identity, expectations post-disclosure, participants' level of involvement in gender-related family processes, perceptions of changes in family relationships, concern for their sibling (including a high degree of attunement to gender-affirming name and pronoun usage), and concern for themselves. Findings from this study suggest the need to engage directly with siblings of TNY to further elucidate their intrapersonal, intra-familial, and extra-familial experiences related to having a TN sibling and determine their unique support needs. Implications for families, clinicians, and communities are discussed.

Illuminating the landscape of sibling relationship quality: An evidence and gap map.

This paper used an evidence and gap map (EGM) to advance the scientific understanding of sibling relationship quality among children aged 2 to 18 years by synthesizing literature on 277 empirical studies from 1985 to 2022 to delineate patterns of study design, sampling, and measurement. Most existing research has utilized majority of White, middle-to-upper class, and/or two-caregiver family samples. Nearly 85% (n = 235) of studies used quantitative methods to measure sibling relationship quality across eight domains: conflict, warmth/affection, quality, cohesion, hostility, power/control, positive engagement, and conflict management. A total of 122 studies used a measure of sibling relationship quality as a predictor of sibling behavior, social, psychological, cognitive, health, or physiological outcomes. Future directions for research are discussed.

Observation of Early Social Interactions in Sibling Dyads: A Systematic Review.

Sibling relationships provide unique social experiences that can vary across the lifespan. Early sibling social interactions (ESSI) have been associated with children's own relationship and developmental outcomes, highlighting the essential role that sibling encounters play, even from a young age. Understanding how these social exchanges occur and unfold and the range of opportunities they provide can shed light on critical aspects of early childhood development and family life. However, the methodological approach used in studying ESSI can influence our understanding of these early experiences. This systematic review aims to delineate the methodological framework adopted in observational studies of ESSI. Through a systematic search of psychology and domain-general databases until March 2023, we focused on studies that addressed bidirectional naturalistic interactions in young sibling dyads (at least one child aged 0-36 months). Of the 713 articles screened, only 63 met the inclusion criteria. Findings regarding three main issues are examined, including sample characteristics, study designs and procedures, and sibling interactive behaviours targeted. Previous research has focused on a diverse range of sibling behavioral exchanges, including cues of children's social skills and relationship quality within mainly ecological contexts. However, limitations in representativeness and standardization have been identified. Future studies should incorporate sequential analyses to fully comprehend the interactive nature of early sibling social encounters.

The experiences of having a sibling with an eating disorder: A systematic review of the literature.

OBJECTIVE: Research on carers in the context of eating disorders (EDs) has predominantly focused on parents and offspring, overlooking the adverse effects EDs have on the lives of siblings. This study aims to shift the paradigm by reviewing the literature in this area. To the authors' knowledge, this is the first review of the literature that broadly captured the lived experiences of siblings without being limited by specific search terms such as coping strategies and levels of psychopathology. METHOD: Six databases (ERIC, MEDLINE, PsycInfo, Pubmed, Scopus, and Web of Science) were searched using predetermined search strings. Quantitative, qualitative, and mixed methods studies were included as long as they were focused on siblings' experiences of having a brother or sister with an ED. No publication date restrictions were applied, and thorough quality assessments were initially carried out before a qualitative analysis of the data was conducted. RESULTS: Twenty-one studies were eligible for inclusion, thematic synthesis yielded six core themes, and 17 subthemes related to the inter- and intrapersonal impacts of the ED on siblings' lives. These themes and sub-themes include fragmentation in family relationships, parentification, and competition and jealousy. CONCLUSION: It is of utmost importance to gain a better understanding of siblings' experiences and needs in relation to EDs. The findings are discussed in relation to the existing literature and theoretical and clinical implications, for example, tailored approaches accounting for siblings' experiences.

Sibling effects on problem and prosocial behavior in childhood: Patterns of intrafamilial "contagion" by birth order.

We investigated longitudinal relations between siblings' problem and prosocial behavior, measured by the Strengths and Difficulties Questionnaire, among different sibship sizes in the UK's Millennium Cohort Study. We identified 3436 families with two children and 1188 families with three children. All children (cohort members and their older sibling [OS]) had valid data on behavior at two time points (in 2004 and 2006). Using structural equation model, we found that for internalizing and externalizing problems, OSs (MOS1 = 6.3 years, MOS2 = 9.1 years at T1) exerted a dominant effect on younger siblings (Mage = 3.12 years at T1; 49.7% boys) across sibship sizes. For prosocial behavior, there was OS dominance in two-child families and youngest sibling dominance in three-child families.
