Associations Between Sibling Relationship Quality and Friendship Quality in Early Adolescence: Looking at the Case of Twins (original) (raw)
Related papers
Bidirectional pathways between twin relationship quality and friendship quality were investigated in a large longitudinal twin cohort. We examined negative and positive relationship features in 313 monozygotic (MZ) twins and 238 same-sex dizygotic (DZ) twins from ages 13 to 14 years, using latent structural modeling. Results showed stronger stability of the twin relationship quality compared to friendship quality. Positive features in the sibling relationship were associated with increased positive features in the relationship with the best friend a year later. In contrast, no significant association between negative sibling relationship features and change in negative friendship quality features was found. These findings speak to the important role of the sibling relationship in the development of good quality friendship relations in twins.
Sibling relationship quality from birth to adolescence: the enduring contributions of friends
Journal of Family Psychology, 2005
The purpose of the present study was to examine continuity in sibling relationships across childhood and to evaluate the degree to which children's experiences with their friends and mothers prior to their sibling's birth predict the quality of the relationship they establish with their siblings in adolescence. Twenty-eight firstborn children, who were 48 months old at the time of their sibling's birth, were observed interacting with their siblings and friends at multiple time points. The level of positive social behaviors demonstrated in their early relationships with friends continued to predict sibling relationship quality in adolescence. Firstborn children who had more positive interactions with friends prior to their sibling's birth demonstrated more prosocial interactions with both their siblings and friends in adolescence and exhibited fewer externalizing behaviors. Longitudinal associations support the hypothesis that the social competencies that young children demonstrate in their early relationships with friends may have enduring significance for their social development.

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 firstbornsecondborn 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.
Do sibling and friend relationships share the same temperamental origins? A twin study
Journal of Child Psychology and Psychiatry, 2003
Background: Friendship and sibling relationships differ in that there is an element of choice in friendships, whilst the latter represent a fixed and given relationship. The present study set out to investigate the temperamental correlates of friendships and sibling relationships, as well as to examine their genetic and environmental components.Method Two hundred and twelve same‐sex twin‐pairs (102 MZ and 110 DZ; 104 male pairs and 108 female pairs) aged between 12 and 15, together with their parents, comprised the sample. The twins themselves reported on both negative and positive aspects of the two relationships, and all family members provided reports of the twins’ temperament (mothers, fathers, and adolescent self‐reports).Results: Analyses revealed that negative aspects of both the sibling relationship and friendship were related to emotionality, while the positive aspects of these relationships were associated with sociability and activity. Genetic influences and the shared...
Young children’s sibling relationship quality: distal and proximal correlates
Journal of Child Psychology and Psychiatry, 2009
Background: Relationships within families are interdependent and related to distal environmental factors. Low socioeconomic status (SES) and high household chaos (distal factors) have been linked to less positive marital and parent-child relationships, but have not yet been examined with regard to young children's sibling relationships. The present study tested direct associations between these distal factors and sibling relationship quality, as well as examining parenting as a potential mediator and/or moderator. Method: One hundred and eighteen families with children aged 4 to 8 years were interviewed and completed questionnaires during home visits. Children provided reports about the quality of their sibling relationships via a puppet interview, and mothers and fathers reported on household chaos and their exertion of harsh discipline. Researchers rated parental warmth towards the children. Finally, parental education and household density were assessed as indicators of SES. Results: Using structural equation modelling (SEM), we found that lower levels of household chaos were related to better quality sibling relationships, and that this link was mediated by maternal warmth and paternal harsh discipline, as well as moderated by maternal harsh discipline. Conclusion: Household chaos was more strongly linked to relationship quality between family members than SES, warranting further research and practical application. The study of children's sibling relationships should take into account inter-relations between proximal and distal environmental factors to fully reveal the complexity of family life.

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.

Journal of Family Psychology, 2010
Theoretically framed by a self-determination perspective on value acquisition and taking into account research into sibling similarity and differences, the current study examined links between sibling relationship quality and adolescents' intrinsic values (benevolence and universalism) and extrinsic values (power, achievement, and materialism). Positive sibling experiences were expected to be positively linked to intrinsic values and negatively linked to extrinsic values, and negative experiences were hypothesized to fuel extrinsic values and thwart intrinsic values. Using a sample of 205 adolescent sibling pairs (older children M ϭ 17.61 years, younger children M ϭ 14.63 years) and multilevel modeling, we assessed within-and between-dyads differences to identify whether the sibling relationship functions as a correlate of values in a similar or different way for 2 siblings. Although siblings were not very similar in their values, sibling competition predicted sibling similarity in higher levels of extrinsic values and lower levels of intrinsic values. Implications for value acquisition research that so far has focused almost solely on parents and failed to acknowledge other processes within families are discussed.
