Non-disabled siblings of individuals with intellectual and developmental disabilities (IDD) usually experience trajectories to gradually intensify their involvement in caregiving. However, non-disabled siblings in Asian countries have been woefully overlooked in research despite the fact that Asian countries hold over half of the world's…

This observational study focuses on prosocial behaviors of children with autism spectrum disorder (ASD) during an interaction with their older, typically developing sibling (TD-Sibs). Twenty-eight sibling dyads, in which the younger sibling was diagnosed with ASD (ASD-Sibs), were video-recorded at home playing a game of their choice. Video…

We conducted a meta-analysis which included 16 sibling-mediated intervention studies that aims to utilize siblings to teach their brothers and sisters with autism spectrum disorder play skills, functional skills, or to decrease unwanted behaviors. In general, results across the studies show that sibling-mediated intervention has medium effect size…

Background: Life expectancy for people with Down syndrome is increasing, but older adults with Down syndrome are at greater risk of developing certain pathologies associated with ageing. When ageing parents can no longer look after their child with Down syndrome, their other children are often expected to shoulder this responsibility. Method: We…

Background: The study examined relations between a number of variables regarding typically-developing adult siblings of individuals with intellectual and developmental disability: involvement in the lives of their siblings with disability, personal resources (self-efficacy and sense of coherence), loneliness, and adjustment.

We studied the effect of the number and characteristics of siblings (sex, age) on school achievement in several grades (kindergarten, first grade, and fifth grade), in two large French cohorts, with more than 16,000 children. Running linear mixed-effects models, we find that, independently of socioeconomic status, having more siblings is…

Ethnic-racial identity (ERI) formation is an important developmental task. Although families are a primary context for ERI socialization, little is known about siblings' role. Accordingly, we applied the Actor-Partner Interdependence Model to longitudinal data from 2 siblings to examine the links between siblings' ERI exploration, resolution, and…

Background: Siblings of children with intellectual disability have unique family experiences, varying by type of disability. Methods: Parents of children with Down syndrome (156) or with Rett syndrome (149) completed questionnaires relating to sibling advantages and disadvantages, experiences of holidays and recreation, and perceived availability…

The purpose of this study, based upon the Double ABCX Model of Adaptation, was to investigate cohesion and sibling relationships in families raising typically developing siblings (TDC) and families raising children with…

Sisters and brothers play an important role in the lives of their siblings with intellectual and developmental disabilities (IDD), starting in childhood and commonly increasing in adulthood. The current study compared typically-developing adult sisters' and brothers' level of involvement in the care of their siblings with IDD. Beyond this, the…
