Siblings play an important role in shaping the developmental trajectories of individuals with autism spectrum disorder. Having siblings has been associated with better social communication, non-verbal communication, and theory of mind abilities in autism spectrum disorder. However, little is known about the impact of siblings on adaptive skill…

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…

This study was conducted to investigate the problematic behaviors of preschool students studying in public and private schools according to certain variables. The research was carried out with 300 students and their parents in private and public kindergartens. A demographic information form prepared by the researcher was used to collect the data.…

The use of differences scores to assess agreement/disagreement has a long and contentious history. Laird (2020) notes, however, that developmentalists have been particularly resistant to discontinue the use of difference scores. One area of developmental science where difference scores are still in regular use is that of parental differential…

Discrepancies in first- (M = 14.97 years, SD = 1.82) and second-born adolescents' (M = 12.20 years, SD = 1.90 years) and their parents' perceptions of parental authority legitimacy (PAL) were examined in a longitudinal sample of 145 predominantly White, middle-class, U.S. families. Utilizing a growth curve modeling approach, changes in the…

This study examined the associations between sibling intimacy and conflict and youths' reports of risky behavior in a sample of adolescents ages 11-20. Participants were mothers, fathers, and sibling dyads in 393 families who were interviewed annually for 3, 4, or 5 years. Multivariate multilevel models tested longitudinal links between sibling…

The sibling relationship of adolescents with and without intellectual disabilities was examined. Participants were 70 sibling dyads--each dyad was comprised of one 12-year old adolescent with (N = 23) or without intellectual disabilities (N = 47). Sibling relationships, behavior problems, and social skills were assessed using mother reports.…

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.…

Demographic and clinical factors may influence assessment of autism symptoms. This study evaluated these correlates and also examined whether social communication and interaction and restricted/repetitive behavior provided unique prediction of autism spectrum disorder diagnosis. We analyzed data from 7352 siblings included in the Interactive…

Significant attention has been paid in the literature to sibling relationships and the effects of birth order, family size, and gender on such relationships. Although these are important areas to study, there is relatively little research on the effects of autism spectrum disorders (ASD) on sibling relationships. The existent research identifies…

This study explores the emotional well-being of older siblings of children who are deaf or hard of hearing and older siblings of children with typical hearing (control group). We interviewed 70 families and had both the parent and the older sibling complete questionnaires on sibling perceptions and relationships. Findings revealed no significant…

We examined the impact of family emotional climate and sibling relationship quality on behavioral problems and adaptation in preschool-aged children. Participants were 63 mothers with a preschool-aged child enrolled in a Southern Arizona Head Start Program. Siblings were identified as children closest in age to target child. Mothers of…

This study examined social skills and behavior of children with disabilities (CWD) and the impact of siblings on these behaviors. Eighty-five CWD diagnosed with Attention-Deficit Hyperactivity Disorder only (ADHD-o), Learning Disability or Learning Problems (LD/LP), ADHD and LD combined (ADHD/LD) or Spina Bifida (SB) and their siblings were…

Investigates changes in children's socioemotional development, achievement, and self-concept after the birth of a sibling. Data from a national longitudinal survey of preschool-aged children, over a two-year and a four-year period, indicate that a sibling's birth accompanied significant, albeit temporary, increases in children's behavior problems.…

Objective: There is a dearth of cross-cultural research on hyperactivity. This article aims to quantify the prevalence of hyperactivity in schoolboys residing in an Arab/Islamic country, Oman. Method: 1,502 Omani schoolboys from eight randomly selected schools representing the urban population of Oman were screened for various indices of…
