Theory of Mind (ToM), a central feature of social cognition, impacts social functioning and academic competencies. Yet, the interplay of ToM and self-concept in academic context remains unknown. This study examines how ToM shapes adolescents' academic self-concept and its association with academic competence, while considering the role of gender…

The current study aims to identify the impact of psychological stress among siblings of autistic children on their academic achievement, as well as identifying differences in the level of their academic achievement according to the variables of the normal brother: gender, age, educational level, and the variables of the autistic siblings: gender…

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 current study contrasted two different hypotheses about the relationship between sibling personality and sibling relationship quality: absolute value and dyadic similarity. The absolute value hypothesis suggests that the level of one sibling's personality will predict sibling relationship quality. The dyadic similarity hypothesis argues that…

This analysis set out to identify associations between birth order and sexual health outcomes, focusing on family involvement in sex education and early sexual experiences. The third National Survey of Sexual Attitudes and Lifestyles is a stratified probability sample survey of 15 162 men and women aged 16-74 in Britain. Logistic regression was…

The purpose of this study was to examine the influences of sibling constellation (sex and birth order) on creativity in the context of China's one-child policy (OCP) and Confucian culture (e.g., preference for male offspring). Participants were recruited from a public university in east China and were asked to complete 2 divergent thinking tests,…

We used structural equation modeling in the Early Childhood Longitudinal Study--Kindergarten Cohort (N = 17,020) to explore the influence of having an older sibling on kindergarten-age focal children's cognitive self-regulation. In model 1, we tested how having a sibling who is generally older than the focal child contributes to the focal child's…

Objective: The purpose of this study was to explore the ways in which social smoking expectations mediate the relationship between adolescent smoking behaviour and the smoking behaviour of family and peers. Design: Descriptive, cross-sectional survey. Setting: Taiwan, Republic of China. Method: The participants were 921 senior high school students…

Although attitudes strongly predict later sexual behaviors, few studies have investigated the factors that influence early adolescent attitudes toward sex. Using a general population sample of urban seventh-grade students (N = 1,736), we examined how supportive parenting, television viewing, perceived social norms, and having a friend and/or…

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…

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,…

Research Findings: Studies of children's prosocial behavior typically focus on prosocial acts with a specific partner (e.g., a friend, peer, or sibling), and comparisons of prosociality in different contexts are rare. To address this gap, the current study examined predictive links among children's spontaneous sharing (a common and important form…

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…

Previous research has demonstrated the protective effect of family and sibling closeness on child adjustment, but fewer studies have investigated how closeness is promoted within families. Guided by Family Communication Patterns Theory, we tested the association between family communication and sibling emotional and behavioral closeness, and…

Despite high prevalence rates of social anxiety disorder (SAD) and high rates of victimization in adolescents, studies on the relationship between these phenomena are missing. In the present study we report associations between SAD and multiple victimization experiences in a community sample of adolescents. A cross-sectional study was conducted on…
