Power in Sibling Conflict during Early and Middle Childhood

Sources of power children use in sibling conflict during early and middle childhood were examined according to French and Raven's typology of power. Participants included 66 dyads with an older (M = 81.8 months, SD = 14.48 months) and younger (M = 56.2 months, SD = 13.03 months) sibling. Data based upon naturalistic observations were coded for conflict issues (object, procedure, and information), power types (coercive, information, and legitimate), power effectiveness (attempts and successes), and resolutions (win/lose and compromise). Siblings used coercive power in object issues and information power in procedural issues. Whereas younger siblings used legitimate power in procedural and object issues including win/lose and compromise outcomes, older siblings used coercive power in win/lose resolutions. Siblings did not differ in their effectiveness of power, but they were most effective when coercive power was employed. Findings are discussed in light of power theory and the development of conflict management skills.     

Affective Qualities of Sibling Disputes, Mothers' Conflict Attitudes, and Children's Theory of Mind Development

Preschoolers' theory of mind (ToM) was examined in relation to emotional features of their conflicts with siblings, using mothers as privileged informants. Fifty-four children aged 3 to 5 years and their 54 mothers took part. Children were given 10 standard false belief tasks and a standardized language test. Mothers completed questionnaires, rated vignettes, and kept a conflict diary to provide detailed data on siblings' conflicts, mothers' conflict attitudes, and mothers' use of mental state language to talk about children's disputes. Results revealed that children's ToM scores were significantly correlated with affective dimensions of their sibling disputes, including more frequent expression of positive emotion while disagreeing and less post-conflict distress. Logistic regression showed these associations were independent of age and verbal ability. Mothers' conflict attitudes were significantly correlated with the affective outcome of their children's disputes but not with the preschooler's level of ToM understanding. Findings are discussed in relation to possible reciprocal influences between ToM development and the growth of affectively positive and constructive conflict resolution skills.     

Sibling Relationships and Social-emotional Adjustment in Different Family Contexts

The aims of this study were to examine family type (nonstep, stepfather, stepmother, and single mother) and sibling type (full‐ and half‐siblings) differences in sibling relationship quality (positivity and negativity), and to investigate links between sibling relationship quality and child externalizing and internalizing problems. The sample included 192 families with a 5‐year‐old target child and an older sibling. In addition, 80 of these families included a third older child. Mothers and the older siblings (8 years and older) completed questionnaires and interviews regarding conflict and support in their sibling relationships, and parents and teachers reported on each child's social‐emotional adjustment. Sibling negativity (conflict, aggression) was highest in single‐mother families and full‐siblings were more negative than half‐ and stepsiblings. There was some evidence that sibling antagonism was associated with more child behavioral and emotional problems, but these effects were moderated by family type.     

Parent and Sibling Influences on the Quality of Children's Conflict Behaviours across the Preschool Period

Parent and sibling influences on children's development of conflict management strategies were examined. Data consist of naturally occurring, in‐home sibling disputes of 37 families at two time points. The siblings were approximately two and four years old at Time 1, and four and six years old at Time 2. Parents' and children's use of conflict strategies that reflect proactive autonomy assertions such as opposition and verbal and physical power were the focus of the current study. Results suggest that parents and siblings play an important role in shaping children's conflict behaviours over time. For instance, parents' reliance on unelaborated opposition to the child, and older siblings' increased use of physical power predicted decreases in younger siblings' ability to assert themselves during conflict. In addition, increased proportions of opposition from a younger sibling was associated with the older siblings using less verbal aggression and using more mature conflict strategies such as justifying their own behaviour to their younger sibling. As sibling conflict is a salient child rearing concern for parents, practical implications are discussed.     

Shared Understanding of Parental Differential Treatment in Families

This study examined the extent to which children and parents have concordant views about parental differential treatment (PDT) and whether such concordance is linked with variations in sibling relationship quality. Seventy‐four 11‐ to 13‐year‐old children, their older siblings, and their parents were interviewed about their experiences with PDT and the quality of the children’s sibling relationships. Levels of agreement about the magnitude, direction, and fairness of PDT were generally low to moderate. However, sibling agreement about the magnitude of parental differential affection and the fairness of maternal control and affection were associated with more positive sibling relationships. Whereas family members were more likely to agree that parental behaviors were fair when they were concordant about the extent to which differential affection occurred, agreement about controlling behaviors was associated with lower levels of agreement about fairness. In addition, the frequency of family discussions about parental behaviors was not linked to shared perceptions of fairness. Results emphasize that capturing the multiple perspectives of family members is crucial for obtaining a comprehensive portrayal of family relationships.     

Older sibling contribution to younger children's working memory and cognitive flexibility

We used structural equation modeling in the Early Childhood Longitudinal Study—Kindergarten Cohort (N = 17,020) to explore the influence of having an older sibling on kindergarten‐age focal children's cognitive self‐regulation. In model 1, we tested how having a sibling who is generally older than the focal child contributes to the focal child's working memory (WM) and cognitive flexibility (CF) upon entering kindergarten. In model 2, we assessed the contribution to the focal child's kindergarten WM and CF of having an older sibling in a non‐proximal age range (age 12–18) or not having siblings relative to having an older sibling in a proximal age range to the focal child (up to age 11). In model 3, we considered the contribution of having an older sister, an older brother, or both an older sister and an older brother of any age. Having an older sibling in general was associated with increased kindergarten WM, whereas having an older sister was related to increased WM and CF. Compared to having a proximal older sibling, having no siblings and having a non‐proximal older sibling were related to decreased WM and CF. Findings have implications for involving siblings in family interventions in early childhood.     

Adolescent Sibling Relationship Quality and Adjustment: Sibling Trustworthiness and Modeling,as Factors Directly and Indirectly Influencing These Associations

The main goal of this study was to examine the direct and moderating effects of trustworthiness and modeling on adolescent siblings' adjustment. Data were collected from 438 families including a mother, a younger sibling in fifth, sixth, or seventh grade (M = 11.6 years), and an older sibling (M = 14.3 years). Respondents completed Web‐based surveys describing sibling conflict and warmth. Siblings reported on trustworthiness and modeling, and mothers described adjustment. Sibling conflict was directly associated with internalizing and externalizing behaviors for both siblings. The older siblings' reports of trustworthiness were directly associated with the outcome measures. The younger siblings' reports of trustworthiness were less directly associated, but a possible salutary effect was most evident under the highest levels of sibling conflict or warmth. Higher sibling modeling was a risk factor for adjustment problems in relations characterized by high conflict. Results support exploring trustworthiness as a key dimension of sibling relations.     

Children's Physiological Regulation and Sibling Conflict as Correlates of Children's Conscience Development

Children's conscience, including the ability to experience guilt and engage in rule‐compatible behavior, develops across early childhood. The current study investigated whether within‐family variation in children's baseline respiratory sinus arrhythmia (RSA) and sibling conflict behavior were associated with individual differences in children's guilt and internalized conduct. Between‐family differences across sibling dyad gender compositions were also examined. A within‐family design that included 70 families with two siblings between the ages of 2 and 5 was utilized. Children's baseline RSA was measured while sitting quietly with their family. Mothers and fathers completed questionnaires that assessed siblings’ conflict behavior, guilt, and internalized conduct. Older siblings had higher levels of guilt and internalized conduct than younger siblings. Results from actor‐partner interdependence models indicated that there were no direct effects of children's baseline RSA. The interaction effects approached significance (p's ≤ .08) suggesting that older siblings’ conflict moderated the association between older siblings’ baseline RSA and both older and younger siblings’ guilt. In contrast, older siblings’ conflict was positively associated with older and younger siblings’ internalized conduct. Guilt and internalized conduct also differed for older and younger siblings in different dyad gender compositions. The results underscore the need for greater clarity regarding the function that siblings serve in promoting children's moral development during early childhood.     

Marital conflict and children's functioning

Marital conflict is a key factor in adjustment problems in children. Research is reviewed indicating that conflicts are stressful for children, and increase their aggression and enmeshment in parental disputes. Field studies, supported by recent experimental tests, indicate that sensitization to destructive conflict occurs, resulting in greater reactivity. Marital conflict can disrupt parenting and attachments, increase aggression between siblings, and even impact extended family members such as grandparents. Intense, aggressive conflicts and those centering on the child are particularly destructive. By contrast, resolution much reduces negative reactions and can be detected through a variety of channels of information.     

Adolescents' Sibling Relationship and Friendship Experiences: Developmental Patterns and Relationship Linkages

The goal of this study was to compare developmental changes in adolescents’ relationship experiences with their siblings versus with their best friends and to determine whether individual differences in adolescents’ sibling experiences were associated with differences in friendship experiences. Participants included 179 firstborn‐secondborn adolescent sibling pairs (N = 358). At the onset of the study, firstborns averaged 15 years of age, and secondborns, 12.5 years of age. Siblings were interviewed individually about their relationship experiences during home interviews each year for three consecutive years. Analyses focused on two relationship dimensions: emotional intimacy and control. Adolescents reported more intimacy with friends than with siblings and more control with siblings than with friends. In the face of these overall patterns, developmental changes in both firstborns’ and secondborns’ reports of intimacy differed across relationships, with sibling intimacy increasing and friendship intimacy decreasing; declines were evident in these two relationships in the case of control. Associations between sibling and friendship experiences were more apparent for control than for intimacy and for secondborns as compared to firstborns. Discussion focuses on the conditions underlying connections between adolescents’ interpersonal relationship experiences.     

Self-representations in Early Adolescence: Variations in Sibling Similarity by Sex Composition and Sibling Relationship Qualities

Self-representations play an important role in adolescent development. This study compared self-representations for siblings and explored whether sibling relationship characteristics are associated with similarities or differences in sibling self-concepts. We examined self-representations of 438 adolescent sibling dyads ( M age younger sibling  =  11.6 years, M age older  =  14.3 years), finding that siblings are, on average, similar in their self-representations. This similarity varied, however, depending on sex composition and sibling relationship qualities. Results indicated that sibling modeling, warmth, and conflict were especially influential in predicting sibling resemblance vs. dissimilarity.     

A longitudinal examination of power in sibling and friend conflict

This study examined use of power resources and power effectiveness during the process and outcome of focal children's disputes with their sibling and friend across early and middle childhood. Participants included 35/46 families; focal children (15 males, 20 females) were observed at the age of four (T1) and 3 years later at the age of seven (T2) at home. Sibling and friend conflict sequences were coded for power resources (coercive physical, coercive verbal, simple information, elaborated information, legitimate), immediate power effectiveness (attempt, success), and conflict outcome. Relationship effects indicated focal children employed coercive physical and legitimate power more with siblings whereas they used simple information power more with friends during the conflict process. Focal children were more effective using legitimate power with siblings than friends in the conflict process whereas information power was used more when focal children won conflicts with friends. Regarding developmental effects, focal children employed more coercive physical power at T1 than T2 and elaborated information power at T2 than T1. In contrast, focal children were more effective using information power and coercion when winning conflicts with friends at T2 than T1. Results highlight variability in children's use of power based on relationship partner and development.     

Getting Along or Getting Your Own Way: The Development of Young Children's Use of Argument in Conflicts with Mother and Sibling

The development of children's use of argument in conflicts with their mother and sibling during their fourth vear, a period of marked changes in their understanding of others, was studied in 49 children observed at home with their mothers and siblings at 33 and 47 months. Children's use of reasoned argument in conflict increased: however, the proportion used for conciliation and compromise decreased, and children used justifications increasingly to support their own position. Mothers, hut not siblings, changed in parallel to the children over this period. Both the initiator of a dispute and children's expression of affect were related to children's use of argument; children used less reasoned argument when they were upset. Results are discussed in relation to differences in the development of children's relationships with mother and sibling and the importance of the link between affective expression and the use of argument in family disputes.     

Conflict Styles and Outcomes in Families with Adolescent Children

The role of conflict in parent–adolescent relationships is a topic of considerable theoretical debate and empirical investigation; however, limited attention has been devoted to the strategies used by family members to deal with disagreements and their outcomes and how they differ from early to late adolescence. This study explored conflict styles and outcomes in a sample of 302 families with adolescent children (total N = 906), of two age groups (13‐year‐olds and 15‐year‐olds). One hundred sixty‐four adolescents (45.7%) are female. Participants completed the ‘when we disagree’ scales. Results from both adolescents and parents confirmed the intensification of conflict from early to middle adolescence, in terms of conflict style (higher aggression, lower compromise) and outcome (lower intimacy). Age trends differ according to gender; in particular, there is evidence of a more difficult position of older girls, and of the worsening of mother–adolescent relationship from early to middle adolescence.     

When Does Parents’ Differential Treatment Have Negative Implications for Siblings?

We compared the extent of parents' differential treatment (PDT) and girls' and boys' perceptions of parents' fairness in middle childhood and adolescence as a function of the gender constellation of the sibling dyad. Further, we examined links between PDT in three domains, parental warmth, parents' temporal involvement, and the allocation of household tasks, and both siblings' self esteem and positivity in the sibling relationship. Participants were mothers, fathers and both first- and secondborn siblings from 385 families. To collect information on siblings' family experiences and well-being, family members were interviewed individually in their homes. During the subsequent 2–3 weeks, 7 evening telephone interviews also were conducted; these focused on siblings' daily activities. Analyses revealed different patterns of PDT for siblings as a function of age and gender constellation, stronger links with self esteem and sibling positivity for perceptions of fairness than for PDT, and different patterns of association with self esteem and sibling relations across domains of PDT. We emphasize the importance of studying the processes through which PDT experiences have implications for siblings.     

‘An Earthquake Shocked Up the Land!’ Children's Communication During Play With Siblings and Friends

The construction of shared meanings strategies (e.g., introductions, extensions) and use of internal state language (e.g., references to mental states) during play were examined across two relationship contexts (siblings and friends) in 65 focal kindergarten‐aged children (M age = 56.4 months; SD = 5.71 months). Strategies to construct shared meanings were associated with play session; specifically focal children employed introductions more often with their siblings whereas positive/neutral responses and prosocial strategies were used more frequently with their friends. Findings regarding birth order position indicated that older focal children were more likely to engage in non‐maintenance (e.g., negative) behaviors and explanations with their siblings whereas younger focal children employed extensions of play ideas more often with their siblings than friends. Associations between shared meaning strategies and internal state language were positively correlated across both relationship contexts, with more significant associations found in the sibling play session. Findings highlight the high level of sophisticated play interaction among children during play; these interactions were rich and varied and are discussed in light of recent research and theory.     

Reported Peer Conflicts of Children in the United States and Indonesia

U.S. and Indonesian 9‐ to 11‐year‐old children (N=147) reported on multiple occasions conflicts that they experienced with peers. The precursors of conflict, behavior during conflict episodes, and resolutions were coded. Teacher ratings of aggression and social preference were obtained. The conflicts of children in both countries most often occurred between friends, were short, amicably settled, and solved without aggression. Indonesian children reported disengaging from conflict more often than did U.S. children, whereas U.S. children more frequently reported using negotiation. Reports of aggression during conflict were associated with U.S. and Indonesian children's teacher‐rated aggression, whereas reports of disengagement were associated with Indonesian children's teacher‐rated social preference and aggression.
