Background: Although many children grow up with more than one sibling, we do not yet know if sibling dyads within families show similarities to one another on sibling affection and hostility. In the present study the hypotheses were tested that (a) there will be significant between family variation in change in sibling affection and hostility and…

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…

Background: Research suggests that institutional care has long-lasting effects on children. However, no study has longitudinally studied infants in an institution and their subsequent development at age four. Methods: Sixty-one adopted children aged four years who had spent their first two years of life in an institution were compared to 39…

Background: The study aimed to confirm previous findings showing links between household chaos and parenting in addition to examining whether household chaos was predictive of children's behaviour over and above parenting. In addition, we investigated whether household chaos acts as a moderator between parenting and children's behaviour. Method:…

Background: Previous studies have found that multiple factors are associated with parent-child relationship quality, but have not distinguished potential sources of between-family and within-family variation in parent-child relationship quality. Methods: Approximately equal numbers of biological (non-stepfamilies), single-mother, stepfather, and…

Background: The aim of this study was to examine the relationship between language and theory of mind in children with autistic spectrum disorders (ASD) and children with moderate learning difficulties (MLD). Previous studies have found a strong association between language and theory of mind in a range of groups, but mostly have not included…

Background: The frequency of parental separation means that increasing numbers of children have fathers who live in different households from mother-and-child; the significance of contact and relationships between children and their nonresident fathers for children's adjustment is receiving growing attention. Lessons from this research are…

Background: Children's relationships with their nonresident fathers, and associations between these relationships, children's relationships with mothers and stepfathers, and the children's adjustment were studied in 162 children from single-parent and stepfamilies, selected from a representative community sample in the UK, studied at 2 time points…

Marked individual differences found among 2- to 3-year-olds in comments about their infant siblings were correlated with differences in comments 3 to 4 years later. Differences in behavior toward sibs at the earlier date were correlated with differences in mothers' accounts of sibling's relationships at 6 years of age. (Author/RH)

Interaction between mother and first-born child before and after the birth of a second child was studied in 41 families, using home observations and interview techniques. (MP)

Triadic interactions between mother, preschool-age first-born, and 14-month-old second-born siblings were studied in 40 families as part of a longitudinal study using home observations. Interaction between mother and second-born exerted an important influence on the behavior of the first-born. (Author/RH)
