Using data from a prospective population based study, the prevalence and psychopathological correlates of sibling bullying in children with and without autism spectrum disorder (ASD) were estimated. There were 475 children with ASD and 13,702 children without ASD aged 11 years. Children with ASD were more likely to be bullied by their siblings…

We examined cross-cultural differences in (1) sibling power balance and (2) the associations between sibling power balance and internalizing and externalizing problems in three separate cross-cultural studies (early childhood, late childhood, and adolescence). The "early childhood samples" consisted of 123 Turkish and 128 Dutch mothers…

Introduction: The presence of comorbid mental illness in individuals with intellectual and developmental disabilities (IDD) has been shown to have additional negative impact on parents and caregivers. However, the impact of such dual diagnoses on typically developing siblings has yet to be examined. Methods: Parents and typically developing…

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: It is well documented that friends' externalizing problems and negative parent-child interactions predict externalizing problems in adolescence, but relatively little is known about the role of siblings. This four-wave, multi-informant study investigated linkages of siblings' externalizing problems and sibling-adolescent negative…

This study investigates the psycho-social characteristics of typically developing children who have siblings with autism and their sibling relationship. Children's adjustment at school, their self-esteem and social relations, as well as their friends' attitudes towards their autistic siblings were examined. Participants were 22 siblings of…

Research Findings: This study examines patterns of sibling relationship qualities or interactional types and their association with family characteristics, parenting, and the characteristics of 1 of those children. Participants were 65 children (34 boys; Time 1 mean age = 51 months), their mothers, fathers, and Head Start teachers. Approximately…

The influence of the broader autism phenotype (BAP) on the adjustment of siblings of children with autism has previously been researched mainly in Western cultures. The present research evaluated a diathesis-stress model of sibling adjustment using a questionnaire study including 80 and 75 mother-typically developing sibling dyads in Taiwan and…

Research Findings: In this examination of associations between sibling interaction patterns and later social outcomes in single- and 2-parent families, 113 kindergarteners took part in naturalistic observations at home with siblings, classmates participated in sociometric interviews, and teachers completed behavior ratings. Sibling interactions…

Links between positive and negative aspects of the parent-child relationship and child adjustment are undisputed. Scholars recognize the importance of parental differential treatment (PDT) of siblings, yet, less is known about PDT in the context of the shared (family-wide) parent-child relationship climate, or about the extent to which positivity…

Employing a multi-method approach, we investigated observed and parent-rated child behavioral inhibition (BI) and maternal reports of their own negative affectivity (NA) as predictors of young children's internalizing problems. Participants were 201 children who were siblings between 2.5 and 5.5 years of age (mean = 3.86, standard deviation =…

Few published studies have reported on the psychological well-being of family members of individuals with Rett syndrome (RTT). Eighty-seven mothers of girls and women with RTT completed a questionnaire survey about their daughters' behavioral phenotype, current health, and behavior problems, and their own and a sibling's well-being. Mothers…

This study examined the effectiveness of an 8-week psychoeducational group program for siblings of children with autism spectrum disorder (ASD). The sample consisted of 38 siblings aged 6-15 years (M = 10.75), allocated to the experimental (n = 22) or control group (n = 16). Self-report questionnaires were administered before and after the…

Variability within the literature investigating typically-developing siblings of children with an autism spectrum disorder suggests that the quality of sibling outcomes may depend on specific factors. For this study, 42 parents of a child with an autism spectrum disorder and a typically-developing sibling provided data via online questionnaires.…

The authors investigated whether the quality of three family relationships (i.e., marital, parent-child, sibling) in intact families are associated with each other and with children's psychosocial adjustment. Data were collected by means of maternal and child reports (N = 88) using standardized instruments (i.e., Marital Satisfaction Scale,…
