Preschoolers' Relational Aggression with Siblings and with Friends

As part of a longitudinal study examining sibling and friend relationships in early and middle childhood, relational aggression by 4-year-olds and their interaction partners in semi-structured free play sessions with siblings and friends was examined during sibling sessions involving both same-gender and mixed-gender sibling pairs. Identifiable acts of relational aggression occurred during many of the interactions observed, but there was also a wide range in the amount of relational aggression produced. Both boys and girls used relational aggression with their siblings much more than they did with their friends. Although boys' and girls' relationally aggressive behaviors occurred at similar rates, the form and function of their relational aggression varied depending on the age and gender of their sibling.     

Human affection exchange: VII. Affectionate communication in the sibling/spouse/sibling‐in‐law triad

This study sought to investigate affectionate communication among members of sibHng/spouse/sibling‐in‐law triads as well as the influence of such communication on relational quality. Under the principles of Affectionate Exchange Theory, affectionate communication among these family members may ultimately serve the evolutionary mandates of viability and procreation. Three hundred twenty‐seven participants, comprising 109 sibling/spouse/sibling‐in‐law triads, completed surveys about their communication of affection, relational satisfaction, and closeness. Consistent with predictions, spouses reported communicating more affection to each other than did siblings, who reported communicating more affection than siblings‐in‐law. The communication of affection by spouses and siblings showed a significant correlation, as did the communication of affection by siblings and siblings‐in‐law, and these correlations were significant even when controlling for the affection communicated in the third relationship in the triad (except for nonverbal support communicated in the sibling and marital relationships). Finally, for all three relational types, affectionate communication was positively correlated with both relational satisfaction and closeness.     

Sibling differentiation: sibling and parent relationship trajectories in adolescence

Studied here were the links between sibling differences in trajectories of change in the qualities of parent-child relationships and the qualities of sibling relationships across a 2-year period in adolescence. Participants were first- and second-born siblings (M age = 14.94 years for firstborns and M age = 12.46 years for secondborns) from 185 predominantly White, working and middle-class families. In home interviews, siblings reported on their dyadic family relationships. For reports of parent-child warmth but not parent-child conflict, results were consistent with sibling differentiation theory: Increasing differences between siblings over time in parent-child warmth were linked to trajectories of increasing warmth and decreasing conflict in the sibling relationship as reported by firstborns, and increasing warmth in the sibling relationship as reported by secondborns. The findings support the view that sibling differentiation may be a strategy for managing sibling conflict and rivalry.     

The development of interpersonal aggression during adolescence: the importance of parents, siblings, and family economics

Latent growth curve modeling employed data from a longitudinal study of 451 sibling families to examine parents, siblings, and family economics as factors in individual differences in the developmental course of interpersonal aggression during adolescence. Findings suggest that individual change in interpersonal aggression during adolescence can be predicted by the gender and aggression of one's sibling; predictions varied by the gender composition of the sibling dyad. Rates of parental hostility predicted levels of interpersonal aggression for both older (mean age = 12 years) and younger siblings (mean age = 15), and growth in aggression for younger siblings. Family economic pressure predicted interpersonal aggression of both siblings indirectly through parental hostility. Implications for future research and preventive interventions are discussed.     

The similarity of siblings' attachments to their mother

Do siblings develop similar attachment relationships with their mother? Attachment theory suggests that brothers and sisters growing up in the same family are likely to relate in similar ways to their parents, at least when parental attachment representations and interactive styles remain stable across time. In the current study, sibling attachment data from three research groups (from Pennsylvania State University, Leiden University, and the University of Western Ontario) have been pooled to assemble a sufficiently large sample of observations (N = 138 sibling pairs) for a detailed comparison of sibling attachment relationships. Spacing between the births, differences in maternal sensitivity, and gender of siblings were examined as possible sources of concordance of nonconcordance. Attachment security (including disorganized attachment) of each sibling was assessed with the Strange Situation procedure between 12 and 14 months after birth. Maternal sensitivity was observed with the same rating scale in a laboratory play session in one of the studies and in home observations in the others. Sibling relationships were found to be significantly concordant when classified as secure/nonsecure (62% concordance, p < .01, 1-tailed, intraclass correlation = .23) but not when further subcategorized. Maternal insensitivity to both siblings (shared environment) was associated with concordance of sibling nonsecurity. Siblings of the same gender were more likely to form concordant relationships with their mother (68%; p < .01, 1-tailed, intraclass correlation = .37) than those of opposite gender. Same-sex sibling concordance was comparable to the concordance found for monozygotic twins in earlier studies. Genetic factors may, therefore, play a relatively small role in the development of attachment.     

Environmental differences within the family and adjustment differences within pairs of adolescent siblings

To what extent do siblings in the same family experience different parental treatment, sibling interaction, and peer relationships? Are such within-family experiential differences related to differences in the siblings' emotional adjustment? The present study explored these questions concerning within-family environment using data from 348 families that each included 2 siblings 11-17 years of age. The results indicate that siblings in the same family experience different environments, as reported by parents and to a larger extent by the siblings themselves. The results also demonstrate that within-family environmental differences are related to differences in development between siblings. Both the parent and sibling reports of the environment converge on the finding that the sibling who is more psychologically well adjusted (as reported by parents, siblings, and teachers) also experiences more maternal closeness, more sibling friendliness, more peer friendliness, more say in family decision making, and more parental chore expectations as compared to the other sibling.     

Children's Vulnerability to Interparental Conflict: The Protective Role of Sibling Relationship Quality

This study tested whether the strength of the mediational pathway involving interparental conflict, adolescent emotional insecurity, and their psychological problems depended on the quality of their sibling relationships. Using a multimethod approach, 236 adolescents (M_age = 12.6 years) and their parents participated in three annual measurement occasions. Tests of moderated mediation revealed that indirect paths among interparental conflict, insecurity, and psychological problems were significant for teens with low, but not high, quality bonds with siblings. High-quality (i.e., strong) sibling relationships conferred protection by neutralizing interparental conflict as a precursor of increases in adolescent insecurity. Results did not vary as a function of the valence of sibling relationship properties, adolescent sex, or gender and age compositions of the dyad.     

Early Attachment Relationships as Predictors of Preschool Children's Emotion Regulation with a Distressed Sibling

The present study examined (1) the emotion regulation of preschool children by observing their emotional responses to a distressed younger sibling during a separation episode; (2) whether children's regulatory responses were related to sibling interaction observed during the separation episode, and (3) whether individual differences in these children's regulatory responses and the quality of sibling interaction could be predicted from early attachment relationships. Older siblings who ignored their younger siblings' distress were more likely to experience personal distress and use avoidant coping strategies. Emotion regulation strategies were related to the quality of sibling interaction such that older siblings who offered comfort to a distressed younger sibling were more likely to express positive affect in sibling interaction, whereas older siblings seeking adult assistance were less likely to engage in conflict and hostile behavior with a younger sibling. Preschool children who had an insecure-resistant infant-mother attachment at 1 year, were more likely to seek comfort from their younger siblings and engaged in more sibling conflict and hostility when they were 4 years old. The quality of infant-father attachment relationships was not significantly related to the child's emotion regulation at 4 years of age. Results are discussed with respect to the social origins of preschool children's emotional self-regulation and the consequences of emotional dysregulation in preschool settings.     

Associations among Family Relationships, Antisocial Peers, and Adolescents' Externalizing Behaviors: Gender and Family Type Differences

This study investigated the relations among parenting, sibling relationship, peer group, and adolescent externalizing behaviors. With data obtained from a sample of 341 male and 313 female adolescents (M age = 14.4 years) and their parents and siblings from nonstepfamilies and stepfather families, cross-sectional analyses supported the hypothesis that the contributions of parental negativity, parental monitoring, and sibling negativity to adolescents' externalizing behaviors would operate directly and also indirectly through deviant peer associations. The findings of multigroup comparison analyses suggested that the relationships between family and peer correlates and adolescent externalizing behaviors vary as a function of family type and adolescent gender.

The quality of infant-father attachment relationships was not significantly related to the child's emotion regulation at 4 years of age. Results are discussed with respect to the social origins of preschool children's emotional self-regulation and the consequences of emotional dysregulation in preschool settings.     

Fathers' and mothers' involvements in sibling communication

The purpose of this study was to measure fathers' and mothers' linguistic involvements with the development of communication between young siblings. In a laboratory setting, 39 two-child mother-father families were videotaped in semistructured activities. The older sibling was from 18 to 26-months-old (M=22.4 months, SD=2.5 months) and the younger sibling was from 4 to 8-weeks-old (M=5 weeks, SD =1.5 weeks). Regardless of type of vocalization, when only one parent was present, utterances encouraging sibling interactions were more often aimed at girls than at boys. As a result, such utterances occurred more when both siblings were girls than for any other gender combination. Fathers were more active in issuing such utterances, especially to girls. When both parents were present, gender differences between parents disappeared, although the effects of children's gender did not. Overall, the results suggest that fathers very actively direct sibling interactions, especially those involving girls.     

Risk of maltreatment for siblings: Factors associated with similar and different childhood experiences in a dyadic sample of adult siblings

Siblings share the same environment and thus potentially a substantial number of risk factors for child maltreatment. Furthermore, the number of siblings and the sibling constellation itself might pose a risk for child maltreatment. Little is known about the likelihood that more than one child in a family is maltreated and which factors increase the risk. This study sought to investigate similarities and differences in maltreatment in siblings and risk factors associated with the maltreatment of more than one child from the same family. Data on maltreatment during childhood and adolescence, family background, and sibling constellation were collected from 870 pairs of siblings. In the dyadic analyses, siblings reported similar maltreatment experiences, especially when any type of maltreatment was considered. Parents’ mental health problems were significant predictors for maltreatment of at least one sibling. Father’s mental health problems were predictive of maltreatment of both or only the younger sibling, mother’s mental health problems of both or only the older sibling. Closeness in age and same gender of siblings did not emerge as a consistent predictor. The increasing number of siblings was a risk factor for any type of maltreatment of both siblings. The results highlight the need for preventive measures for families with a large number of children and with parents with mental health problems as well as a repeated risk assessment of all siblings in a family when one sibling was maltreated.     

The relationship between siblings’ college choices: Evidence from one million SAT-taking families

Recent empirical work has demonstrated the importance both of educational peer effects and of various factors that affect college choices. We connect these literatures by highlighting a previously unstudied determinant of college choice, namely the college choice made by one's older sibling. Data on 1.6 million sibling pairs of SAT-takers reveals that younger and older siblings’ choices are very closely related. One-fifth of younger siblings enroll in the same college as their older siblings. Compared to their high school classmates of similar academic skill and with observably similar families, younger siblings are about 15–20 percentage points more likely to enroll in 4-year colleges or highly competitive colleges if their older siblings do so first. These findings vary little by family characteristics. Younger siblings are more likely to follow the college choices of their older siblings the more they resemble each other in terms of academic skill, age and gender. We discuss channels through which older siblings’ college choices might causally influence their younger siblings, noting that the facts documented here should prompt further research on the sharing of information and shaping of educational preferences within families.     

Children’s sibling relationships and gendered practices: talk,activity and dealing with change

This article addresses children’s sibling relationships as a site of social learning involving the (re)production of femininity and masculinity, drawing on in‐depth qualitative interviews with children aged 8–12. We begin by noting the lack of focus on gender in the majority of previous work on siblings. After introducing our own study, we look at the ways in which children understood their siblings in relation to themselves, highlighting points of closeness and division, and pointing to class distinctions around individuality and collectivity. We then explore how ‘talk’ and ‘activity’ are key gendered features of children’s relationships with their sisters and brothers, revealing versions of femininity and masculinity, and interplays of power. Finally, we consider how these gendered features of sibling practices have implications for children’s ability to deal with change in relationships with their sisters and brothers, especially living apart from each other, and we return to class as a feature of their understandings.     

Siblings exposed to intimate partner violence: Linking sibling relationship quality & child adjustment problems

Although the majority of families that experience intimate partner violence (IPV) have more than one child, most research to date has focused upon a single child within these families. A significant body of research has indicated siblings play an important role in children's adjustment and well-being. To address this gap, the three main goals of the present study were to compare the adjustment of older and younger siblings exposed to IPV, to describe and compare the quality of these sibling relationships from multiple perspectives, and to investigate how sibling adjustment and relationship quality influence children's adjustment. Forty-seven sibling pairs and their mothers were recruited from the community. Mothers self-reported on their violent experiences using the Conflict Tactics Scale, and also estimated the length of time their children were exposed to IPV. Mothers and children completed assessments of child adjustment and the quality of sibling relationships. Observers also assessed the quality of sibling interaction. Results indicated that adjustment between siblings was highly inter-related. On average, mothers reported sibling relationships as less positive but also as less hostile than did siblings themselves. Higher levels of sibling hostility, lower levels of sibling warmth and higher levels of disengagement each significantly predicted child adjustment; however, these effects were predicated upon the adjustment of the other sibling. The sibling relationships of children exposed to IPV made a difference in their individual adjustment, and their adjustment issues influenced how they feel about and interacted with their sibling. Sibling hostility played a stronger role in adjustment issues than sibling warmth. The nature of sibling influences and the direction of future research were discussed.     

Siblings and theory of mind in deaf native signing children

We report a study designed to examine the basis of "theory of mind" (ToM) reasoning in deaf children who are native signers of British Sign Language. The participants were 20 native signers (aged 4-8 years) and their siblings. The children were given a measure of the quality of sibling relations together with a referential communication test concerning physical representations of objects and people. Sibling quality as perceived by siblings predicted children's ToM scores over and above age and referential communication. We conclude that the process of ToM understanding is linked to positive sibling relations that may permit access to knowledge about the inner worlds of beliefs and other mental states.     

Factors Associated with General Partner and Relational Uncertainty within Early Adulthood Sibling Relationships

Guided by the theoretical concept of uncertainty, the present study was an exploratory investigation of general partner and relational uncertainty within sibling relationships. Undergraduate and graduate student participants responded to a written survey utilizing scales measuring general partner uncertainty, relational uncertainty, extent of topic avoidance, and various relational and demographic items. Results revealed that siblings experience significantly more partner uncertainty than relational uncertainty, although both uncertainty types were experienced at low to moderate levels. Further, differing levels of partner and relational uncertainty were associated with frequency of sibling contact, but not with sibling dyadic gender composition. Finally, both general partner and relational uncertainty were significant predictors of levels of general topic avoidance, although neither uncertainty type predicted romantic/sexual relationship topic avoidance levels. Theoretical implications for uncertainty management are discussed in light of the unique sibling relationship.     

Individual Differences in Sibling Teaching in Early and Middle Childhood

Research Findings: Sibling teaching and learning behaviors were investigated in 2 studies of children in early and middle childhood. Study 1 addressed individual differences in teaching/learning and associations with dyadic age, age gap, gender, birth order, and relationship quality in 71 middle-class dyads (firstborns M age = 81.54 months; second-borns M age = 56.27 months). Half of the firstborn and half of the second-born siblings were assigned the role of teacher. Regression analyses indicated that dyadic age and age gap made unique contributions to teacher and learner behavior. Few birth order differences in approaches to teaching/learning were revealed. Findings highlight the reciprocal nature of sibling teaching and learning. Study 2 investigated longitudinal associations between sibling relationship quality and teaching in a second sample (at Time 1 firstborns = 46.8 months; second-borns = 14 months). Positive sibling interaction (including play) at Time 1 was associated with teaching/learning behaviors 4 years later. Practice or Policy: Findings are discussed in light of recent social constructivist notions that children's development is facilitated in the context of intimate relationships.     

Sibling differentiation in adolescence: implications for behavioral genetic theory

The presence of sibling "differentiating processes"--defined as processes in which increased sibling similarity in environmental or genetic factors leads to differences in sibling outcomes-poses a challenge for standard behavioral genetic theory and research. The presence of differentiation processes may affect estimates of genetic and environmental parameters in ways that have not been fully recognized. Utilizing data from the Nonshared Environment and Adolescent Development project, this study examined whether differentiating processes existed for seven composite indices of positive and negative adolescent adjustment. The 720 sibling pairs in the study were broken down into groups by age difference (0-4 years) between siblings. The hypothesis that siblings close in age would demonstrate lower correlations on adjustment measures was generally supported at two time points, three years apart. However, siblings one year apart at Time 1 were more similar to each other than were siblings two years apart, suggesting that shared environmental influences counteract sibling differentiation processes for these siblings. The overall trend supporting sibling differentiation was found to be unrelated to measures of sibling positivity and negativity.     

Do siblings influence one another? Unpacking processes that occur during sibling conflict

This study examined the extent to which 205 sibling dyads influenced each other during conflict. Data were collected between 2013 to 2015. The sample included 5.9% Black, 15.1% South Asian, 15.1% East Asian, and 63.8% White children. Older siblings were between 7–13 years old (Female = 109) and younger siblings were 5–9 years old (Female = 99). Siblings' conflict resolution was analyzed using dynamic structural equation modeling. Modeling fluctuations in moment-to-moment data (20-s intervals) allowed for a close approximation of causal influence. Older and younger siblings were found to influence one another. Younger sisters were more constructive than younger brothers, especially in sister–sister dyads. Sibling age gap predicted inertia in older siblings. Socialization processes within sibling relationships are discussed.
