The purpose of the current study was to use the infant sibling design to explore whether proband traits of autism and ADHD could provide information about their infant sibling's temperament. This could help us to gain information about the extent to which infant temperament traits are differentially associated with autism and ADHD traits. We used…

Loneliness has been associated with several adverse psychosocial outcomes in childhood and adolescence. The present study aimed to investigate feelings of loneliness and social dissatisfaction in school-aged typically-developing (TD) siblings of children with an autism spectrum disorder (ASD). For this purpose, 118 siblings of children with ASD…

The present study examines the link between children's number of older siblings and their cognitive development, as measured by executive function (EFs) skills and verbal skills (VIQ) in a sample of 1,302 4-year-old children (54% boys) living in rural Pakistan. Specifically, we investigate whether the links between the number of older siblings and…

The sibling relationship represents a unique bond characterized by a high degree of closeness and intimacy, which fosters teaching and learning. Two studies investigated associations between sibling-directed teaching, imitation as a learning strategy, and learner involvement during a semi-structured, video-taped construction task. Study 1 also…

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.…

To determine the status of sibling relations among first-born children aged 4-6 years and the influence of parenting style on sibling relationships among rural children, the Sibling Relationship Questionnaire and Parenting Style Questionnaire were used to survey 373 parents of children with sibling relationships who were between 4 and 6 years old…

The two prior studies that have examined associations between the sibling constellation and theory of mind in autism spectrum disorder yielded discrepant findings. Thus, efforts to better understand the sibling-theory of mind link in autism spectrum disorder are necessary. This study examined a sample of prekindergarten- and kindergarten-aged…

The developmental science literature is riven with respect to (a) parental similar versus different treatment of siblings and (b) sibling similarities and differences. Most methodologies in the field are flawed or confounded. To address these issues, this study employed a within-family longitudinal design to examine developmental processes of…

Naturalistic dyadic sequences of teaching and learning involving older and younger siblings were investigated in 39 middle-class dyads over a 2-year period in early childhood. Siblings were observed during ongoing interactions in the home setting for 6 90-min sessions at both Time 1 (older sibling "M" age = 4.4 years; younger sibling…

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.…

Using the NLSY79 and NLSY79 Child and Young Adult Surveys, we investigate the effect of the age difference between siblings (spacing) on educational achievement. Because spacing may be endogenous, we use an instrumental variables strategy that exploits variation in spacing driven by miscarriages. The IV results indicate that a one-year increase in…

Issues of equality and fairness and invasion of the personal domain, 2 previously identified topic areas of adolescent sibling conflict (N. Campione-Barr & J. G. Smetana, 2010), were examined in 145 dyads ("M" [subscript first-born] = 14.97, "SD" = 1.69 years; "M" [subscript second-born] = 12.20,…

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…

Longitudinal data were obtained from 157 children aged 3 years 3 months to 5 years 6 months at Time 1. At Time 2 these children had aged an average of 12 months. Theory of mind (ToM) and executive functioning (EF) were measured at both time points. Results suggest that Time 1 ToM scores predict Time 2 EF scores. Detailed examination of sibling…

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…
