Young people with special educational needs and disabilities (SENDs) and their families have been particularly hard hit by the COVID-19 pandemic. In this longitudinal study, sibling conflict in these families during and after the first lockdown in the United Kingdom was investigated. Online questionnaires were completed by 504 parents of young…

Objective The goal of the current 3-year longitudinal study was to evaluate the association between maternal and paternal parenting styles and sibling relationships during the early to late adolescent transition. Our original sample consisted of 272 participants in grades 9 and 11 from a high school in the Northeastern US. After three years, time…

The validity of the Language ENvironment Analysis (LENA) System was evaluated for Dutch. 216 5-min samples (six samples per age per child) were selected from daylong recordings at 5, 10 and 14 months of age of native Dutch-speaking younger siblings of children with autism spectrum disorder (N=6) and of typically developing children (N=6). Two…

Naturalistic polyadic family conflicts (i.e., involving three or more members) were studied over a 2-year period by comparing disputes originating between siblings (sibling-originated) or a parent and child (parent-child-originated). Conflicts were coded for (a) origination, (b) topic, (c) resolution, and (d) power in 39 families with two children…

This study's objective is to analyse repair sequences for referring problems that occur in conversation with young children (two to three years old), which have shown how reference recognition unfolds along a collaborative process. The results reveal that caretakers frame varying repair questions and that the children locally answer the…

Sibling bullying is highly prevalent and has been found to have adverse effects on mental health lasting into early adulthood. What is unknown is what predicts sibling bullying roles (uninvolved, victim, bully-victim and bully). This study aimed to identify precursors of sibling bullying roles in middle childhood using a large sample of 6,838…

During childhood, older siblings typically hold a more powerful position in their relationship with their younger siblings, but these relationships are thought to become more egalitarian during adolescence as siblings begin to prepare for their relationships as adults and as younger siblings become more socially and cognitively competent. Little…

This study built on research on sibling influences to assess potential bidirectional effects of older and younger siblings' risky behaviors on one another's risky behaviors; our longitudinal design allowed us to test these effects when siblings were at about the same chronological age, at different points in time. We also tested whether the…

Existing research suggests that repeated bullying victimization is associated with lower levels of educational attainment. However, it is difficult to ascertain whether a true causal association exists since previously reported associations may be confounded by genetic and shared environmental factors that affect both repeated bullying…

Research on the home literacy environment has typically involved parents as teachers with little attention given to siblings' roles in teaching each other. This study examines naturalistic language and literacy teaching by 39 sibling dyads, at two timepoints, when children were ages 2 and 4 (time 1; T1) and again at ages 4 and 6 (time 2; T2). Each…

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…

This investigation examines the spread of problem behaviors (substance use and delinquency) between twin siblings. A sample of 628 twins (151 male twin pairs and 163 female twin pairs) drawn from the Quebec Newborn Twin Study completed inventories describing delinquency and substance use at ages 13, 14, and 15. A 3-wave longitudinal actor-partner…

Background: Nonverbal communication deficits are characteristic of autism spectrum disorder (ASD) and have been reported in some later-born siblings of children with ASD (heightened-risk (HR) children). However, little work has investigated gesture as a function of language ability, which varies greatly in this population. Aims: This longitudinal…

Naturalistic dyadic sequences of teaching and learning involving older and younger siblings were investigated in 39 middle-class dyads over a 2-year period in early childhood. Siblings were observed during ongoing interactions in the home setting for 6 90-min sessions at both Time 1 (older sibling "M" age = 4.4 years; younger sibling…

This article reports on findings from longitudinal research that explored perceptions of family life for three- to five-year-old children whose families were participating in an intensive, therapeutic family support programme (N = 5) in a disadvantaged community in Sydney, Australia. There were two early childhood comparison groups, one comprising…
