The present study assesses the factor structure, psychometric adequacy, and invariance across sex and age of the Relational Provisions Loneliness Questionnaire (RPLQ). Discriminant validity with an external criterion was also tested. In a sample of Portuguese adolescents, from 7th to 9th grade (N = 817), Confirmatory Factor Analyses (CFA) were…

In this chapter, the authors review the history of the Waterloo Longitudinal Project (WLP), the first longitudinal study (1980-1992) dedicated to the study of social withdrawal, its correlates, and consequences. Theories underlying the WLP are described, as are its empirical findings. Recent research from other labs that has extended the findings…

The primary objectives of this investigation were to determine the extent to which young adolescents are stable in high perceived popular status across the middle school transition and to examine whether changes in social behaviors predict the stability, gain, and loss of perceived popular status after the transition. The sample included 672 young…

This study examines whether disagreeable youth are distinct from aggressive youth, victimized youth, and withdrawn youth. Young adolescents (120 girls and 104 boys, M = 13.59 years old) completed personality and adjustment inventories. Aggression, withdrawal, and victimization scores were derived from peer nominations (N = 807). Cluster analyses…

Five groups of children were identified using friendship nominations from the fall and spring of their fifth-grade year: (1) children with a stable best friendship with the same child ("same-stable"); (2) children with a mutual best friendship at Times 1 and 2, but the best friend was a different child at each time ("different-stable"); (3)…

Heterogeneity and individual differences in the developmental course of social withdrawal were examined longitudinally in a community sample (N = 392). General Growth Mixture Modeling (GGMM) was used to identify distinct pathways of social withdrawal, differentiate valid subgroup trajectories, and examine factors that predicted change in…

The review of toys and play behaviors notes the existence of two different but somewhat related forms: social play and cognitive play. Nonstructural factors (other than the presence of particular toys) affecting children's play behaviors are examined, as are peer influences on toy use and play. (CL)

A total of 52 first graders were tested on measures of communicative egocentrism and conformity. A three stage heirarchy of decentration skills was postulated. (ED)

This commentary outlines the origins, history, and current status of research related to children's social withdrawal and social isolation. Early research related to children's peer relationships is first explored, followed by a discussion of the relative "neglect" of social withdrawal prior to the 1980s. Increased research attention since that…

The primary objectives of this investigation were to examine the attributions, emotional reactions, and coping strategies of shy withdrawn and aggressive girls and boys "and" to examine whether such social cognitions differ within the relationship context of friendship. Drawn from a sample of fifth and sixth graders (M age=10.79 years; SD=.77), 78…

The authors propose a heuristic model of the social outcomes of childhood brain disorder that draws on models and methods from both the emerging field of social cognitive neuroscience and the study of social competence in developmental psychology/psychopathology. The heuristic model characterizes the relationships between social adjustment, peer…

A total of 18 male and 16 female preschoolers were assessed on observational measures of social interaction and communicative egocentrism. The results indicated negative relationships between the egocentric speech of the child and the incidence of peer interaction. (MS)

Examined factors associated with young children's aggression. Observed 104 toddlers during free play with same-sex peer, with both mothers present. Found that early out-of-home care was not related to aggression. Boys were more aggressive than girls. Observed aggression and mother-reported externalizing problems were associated significantly with…

Seven-year olds (N=55) were administered cognitive measures of communicative egocentrism and moral judgment and were provided with two opportunities to display altruistic behavior; (1) to donate candy to poor children, and (2) to help a younger child complete a task. Success on the two cognitive measures was positively correlated with the…
