- Attachment representations, sleep quality and adaptative functioning in preschool age childrenPublication . Vaughn, Brian E.; El-Sheikh, Mona; Shin, Nana; Elmore-Staton, Lori; Krzysik, Lisa; Monteiro, Lígia Maria SantosBoth the attachment system and sleep are considered to be important biopsychosocial regulators of development and of adaptive functioning in children, and there is a substantial literature suggesting that the two systems may be mutually influencing. To date, however, the bulk of research attempting to link these systems has focused on infancy and the results of empirical studies are mixed. Thirty-nine preschool children participated in this study (valid sleep data for 34 cases). Attachment representations were assessed using the Attachment Story Completion Task (ASCT) and sleep was assessed using objective (i.e., actigraphy) measures. Analyses revealed that the coherence of child narratives and security scored from the ASCT were related to sleep quality indices (e.g., Sleep Activity, Wake Minutes after Sleep Onset, Sleep Efficiency). Additional analyses examined external correlates of attachment representations and tested possible interactions of attachment and sleep. No significant mediated interactions across attachment and sleep domains were found. Although the direction of effects cannot be determined, the results suggest that parent–child relationship and sleep organization are intertwined for preschool age children and the joint effects of these biopsychosocial regulators should be studied further.
- Hierarchical models of social competence in preschool children: A multisite, multinational studyPublication . Vaughn, Brian E.; Shin, Nana; Kim, Mina; Coppola, Gabrielle; Krzysik, Lisa; Santos, António José; Peceguina, Maria Inês Duarte; Daniel, João Rodrigo; Veríssimo, Manuela; DeVries, Anthon; Elphick, Eric; Ballentina, Xiomara; Bost, Kelly K.; Newell, Wanda Y.; Miller, Ellaine B.; Snider, J. Blake; Korth, BryanThe generality of a multilevel factorial model of social competence (SC) for preschool children was tested in a 5-group, multinational sample (N = 1,540) using confirmatory factor analysis. The model fits the observed data well, and tests constraining paths for measured variables to their respective first-order factors across samples also fit well. Equivalence of measurement models was found at sample and sex within-sample levels but not for age within sample. In 2 groups, teachers’ ratings were examined as correlates of SC indicators. Composites of SC indicators were significantly associated with both positive and negative child attributes from the teachers’ ratings. The findings contribute to understanding of both methodological and substantive issues concerning SC in young children.
- Longitudinal analyses of a hierarchical model of peer social competence for preschool children: Structural fidelity and external correlatesPublication . Shin, Nana; Vaughn, Brian E.; Kim, Mina; Krzysik, Lisa; Bost, Kelly K.; McBride, Brent; Santos, António José; Peceguina, Maria Inês Duarte; Coppola, GabrielleAchieving consensus on the definition and measurement of social competence (SC) for preschool children has proven difficult in the developmental sciences. We tested a hierarchical model in which SC is assumed to be a second-order latent variable by using longitudinal data (N = 345). We also tested the degree to which peer SC at Time 1 predicted changes in positive adjustment from Time 1 to Time 2, based on teacher and peer ratings. Using a multiple-method datacollection strategy, information for three subdomains of SC (social engagement/ motivation, profiles of social interaction and personality assets assessed with Q-sorts, peer acceptance) were collected across consecutive years in preschool programs. Longitudinal confirmatory factor analyses (CFAs) demonstrated invariance of both the measurement and the structural models across age levels and yielded a cross-time path weight of .74 for the second-order factor. Analyses of latent means suggested significant increases in SC scores from the first year to second year of participation, and longitudinal cases in their second year of participation had higher scores than did age peers who entered the program as older children. Finally, Time 1 SC predicted increases from Time 1 to Time 2 for SC-relevant indicators rated by teachers and peers (standardized path coefficient of .29, p < .001).
- Social engagement and adaptive functioning during early childhood: Identifying and distinguishing among subgroups differing with regard to social engagementPublication . Vaughn, Brian E.; Santos, António José; Monteiro, Lígia Maria Santos; Shin, Nana; Daniel, João Rodrigo; Krzysik, Lisa; Pinto, Alexandra Maria Pereira Inácio SequeiraThis study tested the hypothesis that social engagement (SE) with peers is a fundamental aspect of social competence during early childhood. Relations between SE and a set of previously validated social competence indicators, as well as additional variables derived from observation and sociometric interviews were assessed using both variable-centered and person-centered approaches (N = 1453, 696 girls) in 4 samples (3 U.S.A., 1 Portuguese). Directly observed SE was positively associated with broad-band measures of socially competent behavior, peer acceptance, being a target of peers' attention, and also with broad-band personality dimensions. Using individual Q-items significantly associated with SE in 3 of our 4 samples, a hierarchical cluster analysis yielded a 5-cluster solution that grouped cases efficiently. Tests on relations between cluster membership and the set of social competence and other variables revealed significant main effects of cluster membership in the full sample and within each individual sample, separately. With the exception of tests for peer negative preference, children in the lowest SE cluster also had significantly lower overall social competence, personality functioning scores than did children in higher SE clusters.
