Sibling violence and agonistic interactions among middle adolescents

Two hundred seventy-two high school juniors and seniors were surveyed regarding their experiences as victims and perpetrators of sibling violence and agonistic interactions with their closest-spaced siblings. Findings support earlier reports that siblings engage in a variety of violent acts directed toward one another and that there are few differences between males and females as to the extent of the behaviors. Subjects reported experiences of negative physical and verbal interactions less frequently than did younger subjects in previous studies, suggesting the need to further examine age-related differences in sibling violence. Discussion focuses on the implications of the present findings and direction for future studies in this area.     

An Initial Look at Sibling Reports on Children's Behavior: Comparisons with Children's Self-Reports and Relations with Siblings' Self-Reports and Sibling Relationships

The authors examined siblings' reports of children's depression, anxiety, and aggression, and their reports of the sibling relationship, and compared them with children's self-reports. In two samples, including 169 sibling pairs (age M = 9.98 years, SD = 1.51), no significant differences emerged in the levels of depression and anxiety found in siblings' reports of children's behavior and children's self-reports, although siblings reported children to have significantly higher levels of aggression than the children self-reported. Age, the difference in ages between siblings, sex, and sibling sex were not related to siblings' reports of children's behavior. The relations between children's and siblings' reports of children's behavior were significant, yet moderate (average r = .22). Both siblings' self-reports of internalizing behavior and their perceptions of aspects of the sibling relationship (affection, rivalry, hostility, and satisfaction with the sibling relationship) explained significant, and unique, variance in siblings' reports of children's internalizing behavior. The findings for aggressive behavior were similar, although siblings' perceptions of affection in the sibling relationship were not significantly related to their reports of children's aggression. The potential uses and benefits of sibling reports of children's behavior, and sibling and family relationships, are discussed.     

Defensiveness in response to aid from a sibling.

Defensive reactions to aid in the context of a close relationship were studied. Young adult siblings reported on their self-esteem, the quality of the sibling relationship, relevant demographic variables, and a variety of components of defensiveness to aid. Consistent with theory, the components of defensiveness were interrelated. A large percentage (52%) of the variance in defensiveness was accounted for by conflict between siblings, dominance relative to one's sibling, low global self-esteem, high self-esteem when comparing oneself with one's sibling, and low levels of feelings of entitlement. Siblings were least defensive in reaction to aid from older and female siblings. Corroboration from a subset of benefactor siblings was obtained. The results are discussed in relation to recent thinking about the nature of receiving support in close relationships and recipients' reactions to aid.     

Adolescents' relationships to siblings and mothers: a multivariate genetic analysis.

Research has consistently demonstrated that children's behavior toward their siblings tends to resemble interactions occurring in the parent-child relationship. This study examined the relative contributions of genetic and environmental influences to the covariation between sibling relationships and mother-adolescent relationships. Reported and observed family interactions were assessed for 719 same-sex sibling pairs of varying degrees of genetic relatedness. The covariance between mother-adolescent and sibling interactions was decomposed into genetic, shared, and nonshared environmental components. The overlapping effects of shared environment on the two relationship subsystems explained most of the covariance. Smaller but significant genetic and nonshared environmental effects were also found. The consistency of these findings with family processes, such as modeling, is discussed.     

Tests of preferences of young deer mice (Peromyscus maniculatus bairdi) for siblings versus nonsiblings

Three experiments were conducted to test the performance of young deer mice (Peromyscus maniculatus bairdi) in associating preferentially with siblings versus nonsiblings. In Experiment 1, neither males nor females preferred caged siblings versus nonsiblings. In Experiment 2, with full contact permitted, nonsibling males were in contact as much as were sibling males. In Experiment 3, with pairs of littermate pairs permitted full contact, there was no significant differential association. Although discrimination and preferences related to kinship have been demonstrated in some species, they cannot be assumed to be universal.     

Growing Up with an Anxious Sibling: Psychosocial Correlates and Predictors of Sibling Relationship Quality

Relationships between young people with anxiety and their non-affected siblings are important for both individuals in the dyad, and for family dynamics throughout the lifespan; however, these relationships are not well understood. This study examined the experience of growing up with an anxious sibling from the sibling without anxiety’s point of view. We measured psychosocial factors associated with sibling relationship quality in 64 young adults with an anxious sibling. Overall, participants with anxious siblings were resilient, reporting comparable sibling relationship quality, anxiety symptoms, and psychological functioning relative to peers without anxious siblings. The contributions of caregiver burden and attributions about the causes of the sibling’s anxiety-related behavior accounted for significant variance in both sibling relationship warmth/closeness and conflict, with responsibility attributions emerging as an individual predictor of conflict. Clinical and research implications for understanding sibling relationships in the context of anxiety, and for the role of attributions in family relationships are considered.     

Parentification of Adult Siblings of Individuals with Autism Spectrum Disorder

Many typically-developing (TD) siblings provide care for their siblings with autism spectrum disorder (ASD), both as children and as adults. Research on parentification (i.e., when children assume responsibilities typically reserved for adults) has been mixed, with some studies supporting positive outcomes for TD siblings and others indicating negative outcomes. Some of these discrepancies may be due to inconsistencies in differentiating types of parentification. The current study examined how different types of parentification during childhood (retrospectively-reported) related to distress outcomes and attitudes about sibling relationships among 41 TD adult siblings of individuals with ASD. Results indicated that parent-focused parentification was positively related with anxiety and stress among TD siblings. Sibling-focused parentification was positively related to stress but was also related to more positive sibling relationship attitudes. Accounting for demographic variables and the other form of parentification, parent-focused parentification was a unique predictor of distress, whereas sibling-focused parentification was a unique predictor of positive sibling relationship attitudes. Although parentification is often viewed negatively, sibling-focused parentification and perceived benefits of parentification may predict positive outcomes. Results suggest that parentification may prove important in understanding the complex nature of sibling relationships. Specifically, strengthening the sibling bond and reducing parent-focused parentification during childhood may curtail sibling relationship problems and general distress in TD siblings later in life.     

Variance Distribution in Sibling Relationships: Advantages of Multilevel Modeling Using Full Sibling Groups

The majority of research on sibling relationships has investigated only one or two siblings in a family, but there are many theoretical and methodological limitations to this single dyadic perspective. This study uses multiple siblings (541 adults) in 184 families, where 96 of these families had all siblings complete the study, to demonstrate the value in including full sibling groups when conducting research on sibling relationships. Two scales, positivity and willingness to sacrifice, are evaluated with a multilevel model to account for the nested nature of family relationships. The distribution of variance across three levels: relationship, individual, and family are computed, and results indicate that the relationship level explains the most variance in positivity, whereas the individual level explains the majority of variance in willingness to sacrifice. These distributions are affected by gender composition and family size. The results of this study highlight an important and often overlooked element of family research: The meaning of a scale changes based on its distribution of variance at these three levels. Researchers are encouraged to be cognizant of the variance distribution of their scales when studying sibling relationships and to incorporate more full sibling groups into their research methods and study design.     

Sibling support in early adolescence: Buffering and compensation across relationships

The current study is an examination of how support from siblings relates to psychological adjustment and academic competence in early adolescence, with a focus on the buffering and compensatory effects of sibling support. Participants were 695 (357 female and 338 male) African-American, Hispanic-American and European-American students in grades 5 through 8. The age range was 11 to 15 (M?=?12.69, SD?=?1.12). Participants were interviewed in school regarding their social support in addition to their familial, economic and environmental risk, psychological wellbeing, and academic competence. Brother support was associated with more positive school attitudes and with higher self-esteem. Sister support buffered the relationship between ecological risk and school adaptation. In terms of a compensatory effect, students under low mother support conditions receiving greater support from brothers exhibited higher school achievement. The current study highlights the importance of examining constellation variables as part of the broader interest in sibling relations. Additionally, the current study indicates that the variability in sibling relationships reported in the literature may be associated with developmental changes in these relationships. The potential benefits of sibling support warrant a closer examination of the wide-ranging issues involved in sibling relations.     

Siblings of Children with disabilities: Psychological and behavioural characteristics

The purpose of the current study was to assess the behavioural and psychological characteristics of siblings of children with disabilities and the perceptions of parents and children regarding sibling relationships. Participants included 32 children between 6 and 13 years of age, one-half with a younger sibling with a disability and one-half with a younger sibling without a disability. Analyses revealed a difference in children's perceptions of maternal partiality, with siblings of children with disabilities perceiving their mothers to be more partial to their siblings than did siblings of children without disabilities. Further, parents of children with disabilities indicated a greater difference in status/power between their child and his/her younger sibling than did parents of children without disabilities. No significant differences were found between groups on measures of behaviour problems, social competence, or self-esteem, supporting other research that has failed to find negative outcomes for siblings of children with disabilities. The implications of these results for parents and professionals are discussed.     

Children's perceptions of the sibling relationship in middle childhood: Connections within and between family relationships

Although sibling warmth and hostility have been shown to be statistically independent, they are intertwined in children's everyday experiences. We developed a multidimensional characterization of children's perceptions of their sibling relationships and examined differences in other family relationship measures as a function of different combinations of sibling hostility and warmth. Participants included 91 firstborn children between 10 and 11 years of age with younger siblings between 6 and 10 years of age. Children reported their levels of satisfaction, intimacy, and rivalry in their sibling relationships and their satisfaction with parent-child relationships. Parents rated their marriages. As compared with children in families with “affect-intense” sibling relationships (high hostility/high warmth), children in “hostile” sibling relationships (high hostility/low warmth) rated their sibling and parent-child relationships more negatively, and their parents rated their marriages more negatively. Results are discussed in terms of the role of hostility in sibling experiences and the importance of understanding multidimensional patterns in the sibling relationship.     

Interpersonal responses among sibling dyads tested for BRCA1/BRCA2 gene mutations.

OBJECTIVE: The familial context plays an important role in psychosocial responses to genetic testing. The purpose of this study was to compare sibling pairs with different combinations of BRCA1/BRCA2 test results on measures of affect, interpersonal responses, and physiological reactions. DESIGN: Forty-nine sibling dyads with different combinations of BRCA1/BRCA2 test results (i.e., mixed, positive, negative) completed a questionnaire, and 35 of the dyads also participated in a laboratory-based discussion of genetic testing. MAIN OUTCOME MEASURES: The primary outcome variables included participant reports of supportive actions toward their sibling, state anger and anxiety, perceptions of sibling behavior, and electrodermal responses. RESULTS: Compared to positive and negative dyads, mixed pairs reported less friendly general support actions, noted more anger, and perceived their sibling to be less friendly and more dominant during the interactions. In comparisons between same-result (i.e., positive, negative) pairs, positive dyads reported more dominant support behaviors and perceived their sibling to be friendlier during the interactions. CONCLUSION: Data suggest that siblings who have different test results may experience more interpersonal strain than siblings who have the same test result. Future research on genetic testing and family relationships can expand upon these findings.     

Psychosocial adjustment and peer competence of siblings of children with Attention-Deficit/Hyperactivity Disorder

Preliminary data examined the relationships between mothers, their sons with Attention-Deficit/Hyperactivity Disorder (ADHD), and younger siblings. We hypothesized that the conflict between the mother and the son with ADHD would also occur in the relationship between the child with ADHD and the younger sibling. Significant associations were found among ADHD behaviors, family conflict variables, conflict in the relationship between mother and child with ADHD, conflict in the relationship between mother and younger sibling, and conflict in the relationship between the child with ADHD and the younger sibling. Further, significant associations were found between behavior symptoms associated with ADHD and more problematic family relationships. Of particular interest was the finding of an unexpected inverse association between siblings' peer competence and mother-ADHD conflict; specifically, that conflict occurring at home from ADHD accounted for a greater percentage of the variance in peer competence as rated by teachers. Recommendations are made for future research with larger samples, alternative designs, older siblings, and fathers.     

Attachment states of mind and the quality of young adults' sibling relationships

This report examines young adults' states of mind regarding their early attachment experiences in relation to the observed and perceived quality of their sibling relationships. Sixty sibling pairs (18-25 years of age) were (a) administered the Adult Attachment Interview (George, Kaplan, & Main, 1985), (b) videotaped during a conflict resolution task, and (c) asked to describe the quality of their relationship using the Adult Sibling Relationship Questionnaire (Stocker, Lanthier, & Furman, 1997). As hypothesized, dismissing states of mind were associated with lower levels of positive and negative affect while participants attempted to resolve an area of conflict with a sibling as well as with relatively low levels of reported warmth in the relationship. In contrast-but also in line with predictions-preoccupied states of mind were associated with heightened expression of negative affect toward a brother or sister, and the siblings of highly preoccupied individuals reported more conflict in their relationships. Findings provide further support for the importance of young adults' representations of childhood attachment experiences with respect to the quality of their adult relationships. In addition, this study extends previous findings regarding the significance of dismissing versus preoccupied states of mind by demonstrating that these dimensions are differentially associated with behavioral and self-reported aspects of sibling relationship quality in early adulthood.     

Understanding of ASD by Siblings is Associated with Warmth and Hostility in the Sibling Relationship

Autism Spectrum Disorder (ASD) impacts not only the child with ASD, but also the entire family system, including siblings. The present study examined perceptions of the sibling relationship in brothers and sisters of children with ASD, as well as how understanding of autism (symptoms, long-term implications of the disorder) in siblings of children with ASD is related to the sibling’s perceptions of quality of the sibling relationship. Siblings (N?=?44, Mean Age?=?10.4 years, SD?=?2.6) of children with ASD were administered an interview assessing their understanding of ASD and self-report questionnaires measuring their perception of the sibling relationship quality. The more siblings understood about ASD, the more hostility they reported by their sibling with ASD. Age of the sibling, conversely, was negatively associated with both hostile and warm behavior by the brother or sister with ASD towards the sibling. More understanding of autism may be associated with more contention within the sibling relationship, whereas older siblings may spend less time with their brother or sister with autism. Results have implications for improving sibling relationship quality, as well as elucidating the complexity of sibling relationships. These findings have further implications for the development of support systems with use of coping skills for improving the quality of the sibling relationship.

Cultural variation in the social organization of problem solving among African American and European American siblings

This study examined the social organization of a problem-solving task among 15 African American and 15 European American sibling pairs. The 30 sibling pairs between the ages of 6 and 12 were video recorded constructing a marble track together during a home visit. African American siblings were observed to collaborate more often than European American siblings who were more likely to divide up the labor and direct each other in constructing the marble track. In addition, older European American siblings made more proposals of step plans than older African American siblings. The findings provide insights into the cultural basis of the social organization of problem solving across African American and European American siblings.     

Young adult sibling relations: the effects of perceived parental favoritism and narcissism

The present study examined predictors of siblings' relations in 202 young adults (aged 21-32 years), who completed the Adult Sibling Relationship Questionnaire and the Narcissistic Personality Inventory. Results indicate that warmth between siblings is explained by gender (with women feeling closer), perceived paternal favoritism, low levels of narcissism, and an interaction suggesting that paternal favoritism moderates the link between narcissism and sibling warmth. Conflict between siblings was explained by gender (sisters), age, parental favoritism, high levels of narcissism, extreme levels of similarity or dissimilarity between siblings, and interactions indicating that older age is a predictor of conflict between siblings among women but not among men. The impact of parental favoritism and narcissism on sibling relationships in young adulthood was discussed.     

Gender Differences in Emotional Closeness Between Preschool Children and Their Mothers

The emotional closeness between mothers andtheir children was examined to determine if motherdaughter pairs exhibit closer emotional relationshipsthan mother son pairs. Forty-one mother childpredominantly Caucasian dyads were videotaped during asemistructured play setting. The children were 4 (10males and 10 females) and 5 years of age (10 males and11 females). Emotional closeness was defined as physical proximity, mutual eye contact, and global levelof enjoyment. Results demonstrated that compared toboys, girls were physically closer to their mothers,engaged in more mutual eye contact with their mothers, and were rated higher on global enjoyment.Results are consistent with Chodorow's theory thatgender identity development is related to the emotionalrelationships that develop between children and their mothers.
