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…

Qualitative instrumental case study analysis of adult siblings from 2 families explores how socioeconomic inequality among them affects their relationships to one another. Eight middle-aged siblings' observations of childhood, parental expectations, work and family history, lifestyle, and current sibling ties indicate that childhood…

Background: Although the protective effects of familial and parental support have been studied extensively in the child psychopathology literature, few studies have explored the protective quality of positive sibling relationships. Methods: A two-wave longitudinal design was used to examine the protective effect of positive sibling relationships…

Using a large-scale Dutch national sample (N = 7,126), the authors examine the importance of similarities and differences in the sibling dyad for the provision of support. Similarities are assumed to enhance attraction and empathy; differences are assumed to be related to different possibilities for exchange. For helping with housework, helping…

While deficits in social interaction are central to autism, the sibling relationship has been found to provide a key medium for the development of such skills. Naturalistic observations of sibling pairs including children with autism and controls with Down syndrome were made across two time periods, twelve months apart. Consistent with the…

Background: As adults with Down syndrome live increasingly longer lives, their adult siblings will most likely assume caregiving responsibilities. Yet little is known about either the sibling relationship or the general functioning of these adult siblings. Using a national, web-based survey, this study compared adult siblings of individuals with…

"Twins have often served science but science has rarely served twins" (Novotny, 1988). Twinship presents specific challenges unique to twins in the realms of physical, emotional, social, interpersonal, and academic trials; twins many times suffer in self-esteem, separation-individuation, and object relations. This paper reviews literature which…

This study examined the Family Relationships Grid (FRG), a new measure of family structure that evaluates alliances, identification, isolation, and the relative strength of sibling and marital relationships. Subjects were 52 female and 35 male adolescents who were recruited through a university course and who each had at least one sibling.…

A study examined the interactions of siblings in television families in three popular sitcoms of the 1950s--"Father Knows Best,""Leave it To Beaver," and "Ozzie and Harriet." Nine episodes of each sitcom were videotaped, and the behaviors were coded using a system developed to code sibling behavior in 1980s sitcoms.…

Examined four-year olds' use of mental state terms in conversations. Found that more references to mental states were made in conversations with siblings and friends than with mothers. Frequent use of terms by both partners was related to cooperative interaction in child-friend and child-sibling dyads. Found associations with measures of language…

Examined family- and sibling-type differences in sibling relationship quality and links between sibling relationship quality and child behavior problems among 192 families with a 5-year-old target child and an older sibling. Found that sibling negativity was highest in single-mother families. Found that full-siblings were more negative than half-…
