Purpose: Individuals with proximal 16p11.2 copy number variants (CNVs), either deletions (16p11.2DS) or duplications (16p11.2Dup), are predisposed to neurodevelopmental difficulties and disorders, such as language disorders, intellectual disability, and autism spectrum disorder. The purpose of the current study was to characterize language…

Extending the topic of power, control, and influence in the sibling relationship past the years covered in this issue is not an easy task because most adult siblings neither interact frequently nor live in geographic proximity, although there are considerable ethnic and social class variations. Thus, there are limited opportunities to observe how…

Chinese international graduate students (CIGs), growing up without siblings, under China's One-Child policy, are particularly impacted by peer dynamics. This study explored the influence of peer dynamics and family structure on the academic motivation of CIGs in the U.S., using Bandura's self-efficacy theory as a framework. A single-case study…

Research on siblings of children with developmental and physical disabilities has emphasized negative influences on siblings' mental health. Yet, such siblings may be more prosocial compared with siblings of children without disabilities, due to care responsibilities and their experiences with their brother's or sister's disability. We compared…

In India, people with disabilities often struggle to access various opportunities and resources. As a result of perceptions within the Indian culture around disabilities, families may face social, financial, and emotional difficulties.

The balance of power and control is an understudied, yet important, aspect of the sibling relationship that is theorized to shift over the course of development from early childhood to young adulthood. The investigations in this issue offer support for this overall progression, but extend prior research by providing a nuanced understanding of…

The goal of this study is to propose the Siblings' Experience Quality Scale (SEQS), a measure for the assessment of cognitive, emotional and behavioral experience of adult individuals having a brother or sister with an intellectual/developmental disability, chronic physical illness or mental illness, on five dimensions: Closeness, Conflict,…

The research was the correlational model. The data of the study were collected from a total of 1427 students from 20 different schools in five randomly selected…

Emotion dysregulation is a common challenge for autistic individuals, yet research examining early emotion regulation processes in autism is lacking. The present study examined negative emotion expression and parent-child co-regulatory processes in 18-month-old younger siblings of autistic children (children with an "elevated likelihood"…

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…

Despite the prevalence of studies showing increased stress among mothers of individuals with autism spectrum disorders, few studies have examined general stress among typically developing siblings. This study used an online survey to compare the levels of self-reported stress between adolescent siblings of individuals with autism spectrum disorder…

Through analysis of a video recording of two bilingual siblings playing with rubber ducks, this article explores the concept that imaginative play can serve as a potential site for language shift. The article argues that the siblings use English as a means to 'double voice' (Bakhtin, M. M. (1981[1963]). "The Dialogic Imagination" (C.…

Emotion understanding develops rapidly in early childhood. Firstborn children (N = 231, 55% girls/45% boys, 86% White, 5% Black, 3% Asian, 4% Latinx, Mage = 29.92 months) were recruited into a longitudinal study from 2004 to 2008 in the United States and administered a series of tasks assessing eight components of young children's emotion…

Inclusion of students with Autism Spectrum Disorder (ASD) in mainstream schools has a positive impact on their social and daily living behaviors. Our objective was to identify clinical and socio-demographic variables promoting or limiting inclusion in mainstream school through childhood and adolescence. The EpiTED study is a long-term,…
