General contact patterns, obligatory contact motivation, and discretionary contact motivation were examined regarding sibling relationships among 313 urban adults aged 25 or older. Emotional closeness, sibling responsibility expectations, and geographic proximity were most important in explaining dimensions of sibling interaction. (Author/TE)

Two case studies in which siblings are seen together and separately provide the basis for discussing the importance of evaluating the needs and circumstances of children placed in foster care. (SW)

This study examined the impact of maternal labeling of children as gifted on the sibling relationship in 144 pairs of firstborn and secondborn siblings classified as both gifted, firstborn gifted, secondborn gifted, or neither gifted. Five aspects of the sibling relationship were examined: warmth/closeness, status/power, conflict, maternal…

Evaluation of ascribed, parent-mediated child care roles of younger same-sex siblings of children with mental retardation (n=32) found role reversals evident in the sibling pairs consistent with roles assumed by siblings during observed interactions. Increased younger sibling child care roles were related to less conflicted sibling relationships.…

Four experiments and an analysis of pooled data from English and Japanese children show a linear increase in understanding false beliefs with number of older siblings; no such effect for children younger than 38 months; no helpful effect of younger siblings at any age; no effect of siblings' gender; and no helpful effect of siblings on a source…

Explores whether the effects of sibling birth are mediated by associated changes in the family environment and changes in family members' interaction patterns. Data from a national longitudinal survey indicate that the birth of a sibling lessened positive interactions with the older child and mothers increasingly adopted controlling parenting…

Compared pretend play enactment, negotiation, internal state language, and sibling relationship quality in 40 kindergartners with older or younger siblings. Found that frequent pretend play dyads used more high-level negotiation and internal state language than infrequent pretend dyads. Friendly relationship quality was negatively related to…

Differences and similarities between 245 brothers and sisters of adults with mental retardation in the sibling relationship were examined. Sisters scored higher in the caregiving, companionship, and positive affect aspects of the sibling relationship. Sibling involvement increased over time, but was dependent upon changes in maternal health.…

For 39 sibling dyads, assessed siblings' relationships through observation and maternal interviews at 4 times, and family life events through maternal interview at 3 times, over a 7-year period beginning when the younger sibling was 3. Found stability of individual differences in the sibling relationship increased with age and that life events…

Examined how sibling relationships were portrayed in a sample of 261 children's books, as well as how parents were depicted when responding to sibling conflict. Found that although children's books often represented warmth and involvement between siblings, they rarely described conflict management or relational maintenance activities. Parents were…

Children often learn and apply behaviors in sibling interactions before they routinely use such behaviors in peer interactions. As part of a longitudinal study of relational aggression, 46 children were videotaped at home in semi-structured free play situations with siblings and with friends at age 4 and again at age 8. Observations revealed that…

We examine affective closeness, contact, and helping among adult siblings using data for over 1,500 respondents in 2-child families from the National Survey of Families and Households. Using this subsample allows us to investigate differences by gender of respondent and of individual siblings using a nationally representative sample. We find that…

Previous research has shown a strong connection between birth weight and future child outcomes. But this research has not asked how insults to child health after birth affect long-term outcomes, whether health at birth matters primarily because it predicts future health or through some other mechanism, or whether health insults matter more at some…

This study examined the substance use and delinquency outcomes for the nearest age siblings of substance abusing and delinquent adolescents that participated in a randomized clinical trial evaluating the effectiveness of integrating evidence-based practices into juvenile drug court. The sample of 70 siblings averaged 14.4 years of age, 50% were…

Background: Antisocial behaviour is often comorbid with depressed mood but is itself a collection of heterogeneous behaviours. Using a genetically informative design, we examine heterogeneity in antisocial behaviour and overlaps between different forms of antisocial behaviour with depressed mood. Methods: Data were drawn from the G1219 large-scale…
