Stressful life events and experiences may disrupt the typical day-to-day interactions between sisters and brothers that provide the foundation of sibling socialization. This chapter examines four experiences that may affect patterns of sibling interaction: parental marital conflict, parental divorce and remarriage, foster care placement, and a…

This study investigates whether preschool-aged children show consistent patterns of behaviour in conflicts with their siblings. Consistency was assessed at the nomothetic (i.e., group), idiographic (i.e., individual), and idiosyncratic (i.e., consistent patterns that differed from the norm) levels. We examined conflicts between 19 2-year-old and…

This article investigates the perceptions of 12 teachers from New South Wales, Australia, regarding the classroom assignment of twins. Analysis of semi-structured interviews with each of the teachers revealed four key findings: 1) teachers' perceptions about the classroom assignment of twins vary according to their previous experience and…

This study examined social problems at school and relationships with peers, siblings, mothers, and fathers among children with ADHD only (n = 41), ODD only (n = 14), ADHD + ODD (n = 47), and normal controls (n = 204) from a school-based sample of 2,463 first to ninth graders in Taiwan. ADHD and ODD symptoms were determined by teacher and mother…

Including more than one child per family in research enables the identification of nonshared family effects (resulting in sibling differentiation) as well as shared family effects (resulting in sibling similarity). This paper describes a model used to disentangle shared from nonshared processes in links between parenting and children's behavior.…

Previous research has revealed only modest concordance in attachment security between siblings during childhood and adolescence. The first goal of this dissertation was to estimate sibling concordance in adult attachment security and identify factors contributing to divergence. The Adult Attachment Interview (AAI) was administered to young adult…

Because characters with developmental disabilities (DD) in children's books are often the first images many children encounter, their accurate and multidimensional portrayal is critical. Therefore, the depictions of characters with DD in 41 children's books were analyzed. These books were eligible for the biennial Dolly Gray Children's Literature…

Empirical research on sibling abuse has been overwhelmingly absent from the professional literature. This exploratory study used a survey instrument to investigate the question of whether the experience of sibling abuse influences the sense of well-being in college students. A linear multiple regression analysis indicated that experience with…

Objective: This study investigated the quality of sibling relationships among children with ADHD relative to those without ADHD. Additional analyses examined whether externalizing and internalizing problems comorbid with ADHD affected sibling relationships. Method: Participants were 77 children with ADHD and 14 nonproblem control children. Sibling…

This study investigates the psychosocial adjustment of hearing siblings of deaf and hard of hearing (d/hh) children, as well as the quality of the relationships between siblings and between hearing siblings and mothers. Thirty families from Cyprus took part in the study. Self-report data were collected from the mothers and the hearing siblings.…

Research Findings: Sibling pretend play, collaboration, and creativity during maternal presence and absence were investigated in 24 dyads in early and middle childhood (younger siblings' M age = 5.3 years; older siblings' M age = 8.2 years). Associations between sibling behavior and maternal interaction (e.g., guidance, positive responses) were…

This study examined siblings' teaching strategies in 72 dyads (firstborn and second born, M ages = 81.64 and 56.31 months) as a function of dyad age, age gap between siblings, and teacher birth order. One child per dyad was randomly assigned to teach her or his sibling to construct a tractor toy. Interactions were coded for the topic of teachers'…

Guided by an ecological framework, we explore how siblings' and parents' roles, relationships, and activities are intertwined in everyday life, providing unique and combined contributions to development. In a departure from past research that emphasized the separate contributions of siblings and parents to individual development, we find that…

In two studies, fifth- and sixth-grade children's descriptive accounts of sibling jealousy were related to their implicit theories about relationships. Children's jealousy accounts were collected via structured interviews; their implicit theories were assessed by questionnaire. In both studies, children reported experiencing mild to moderate…

This study examined the nature and correlates of adolescents' perceptions of sibling influence. Participants included 2 siblings (firstborn age M = 17.34; second-born age M = 14.76 years) from 191 maritally intact families. Adolescents' perceptions of sibling influence were measured via coded responses to open-ended questions about whether their…
