- Associations between attachment security and social competence in preschool childrenPublication . Veríssimo, Manuela; Santos, António José; Fernandes, Carla; Shin, Nana; Vaughn, Brian E.Attachment theorists suggest that attachment security with parents supports the quality of social adaptation in peer groups during early childhood, and numerous studies supporting this conjecture have been published. Most of these studies used enacted representations rather than mental representations of attachment security, and most studies examining mental representations used adult (parent or teacher) ratings of peer-group adaptation. Our study tested relations between preschool children’s (N = 147; age 48–69 months) mental representations of attachment by using the Attachment Story Completion Task and child-level indicators of social competence based on direct observations and sociometric interviews. General intelligence tests were administered to control for effects of developmental level on child narrative production. Analyses revealed positive, significant associations between attachment measures and all social competence composites. Children with more secure attachment representations were more socially engaged and more likely to exhibit social, emotional, and cognitive skills that contribute to peer acceptance. Results support the hypothesis that attachment security is a foundational support for peer social competence.

- 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.
- Auto-conceito e representações da vinculação no período pré-escolarPublication . Maia, Joana Branco; Ferreira, Bruno; Veríssimo, Manuela; Santos, António José; Shin, NanaA Teoria da Vinculação sugere que as representações internas das experiências relacionais e a noção de self vão sendo interiorizadas, de forma complementar, pelas crianças ao longo do tempo, desempenhando as figuras de vinculação um papel crucial neste processo. Alguns estudos empíricos (Cassidy, 1988; Clark & Symons, 2000; Verschueren, Marcoen, & Schoefs, 1996) têm examinado as ligações entre desenvolvimento do self e segurança da vinculação durante o período pré-escolar. No entanto, poucos se têm debruçado, especificamente, sobre as associações existentes entre o auto-conceito dos sujeitos e as representações internas que estes possuem das suas experiências relacionais, como é o caso do presente estudo. Para inferir a qualidade e a segurança das representações de vinculação utilizámos uma versão adaptada da MacArthur Story Stem Doll-play Task (Page & Bretherton, 2001) numa amostra de 75 crianças do pré-escolar. A representação do self foi avaliada através da versão portuguesa da Pictorial Scale of Perceived Competence and Social Acceptance for Young Children (Harter & Pike, 1984; Mata, Monteiro, & Peixoto, 2008). Os resultados encontrados apoiam a presença de relações entre a qualidade das representações associadas à vinculação e a representação global que a criança tem do seu self, com uma associação positiva mais forte a ser encontrada com a percepção da Aceitação Social.
- A concordância entre o comportamento de base segura com a mãe nos primeiros anos de vida e os modelos internos dinâmicos no pré-escolarPublication . Silva, Filipa; Fernandes, Marília; Veríssimo, Manuela; Shin, Nana; Vaughn, Brian E.; Bost, Kelly K.Estuda-se, numa amostra que contempla dois países – Portugal e Estados Unidos da América –, a estabilidade da qualidade da vinculação, na relação mãe criança, analisando-se o comportamento de base segura na relação mãe-criança nos primeiros anos de vida e as representações mentais da criança acerca desta relação, no pré-escolar. Os participantes são 25 díades mãe-criança portuguesas e 47 díades mãe-criança americanas. Utiliza-se o Attachment Behaviour Q-Set (AQS) (Waters, 1995) para avaliar os comportamentos de base segura e, três anos mais tarde, aplica-se às crianças o Attachment Story Completion Task (ASCT) (Bretherton & Ridgeway, 1990) que avalia a qualidade e a segurança das representações internas da relação de vinculação. Os resultados mostram que, nesta amostra, há uma estabilidade da vinculação entre os 2-3 anos de idade e os 5-6 anos de idade. O valor de segurança do AQS está correlacionado positiva e significativamente com a dimensão de segurança do ASCT. Nesta amostra, os modelos internos dinâmicos parecem permanecer relativamente estáveis ao longo de um período significativo de tempo.
- Growth of social competence during the preschool years: A 3-year longitudinal studyPublication . Santos, António José; Vaughn, Brian E.; Peceguina, Maria Inês Duarte; Daniel, João Rodrigo; Shin, NanaThis study examined the stability and growth over a 3-year period of individual differences in preschool children’s social competence, which was assessed in three domains: social engagement/motivation, profiles of behavior and personality attributes characteristic of socially competent young children, and peer acceptance. A total of 255 children (126 girls and 129 boys) participated in this study. Growth curve analyses demonstrated both stability and change with regard to social competence over early childhood. Social competence measures and latent variables were invariant over this time period, individual differences in social competence were largely stable from year to year, and significant increases over time were observed for the domain most closely reflective of specific personal attributes skills.
- 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).
- Preschool children’s mental representations of attachment: Antecedents in their secure base behaviors and maternal attachment scriptsPublication . Wong, Maria; Bost, Kelly K.; Shin, Nana; Veríssimo, Manuela; Maia, Joana Branco; Monteiro, Lígia Maria Santos; Silva, Filipa; Coppola, Gabrielle; Costantini, Alessandro; Vaughn, Brian E.This study examined the antecedents of preschool age children’s mental representations of attachment, assessed using the Attachment Story Completion Task (ASCT). Antecedent predictors were maternal attachment scripts, assessed using the Attachment Script Assessment (ASA), and the child’s secure base behaviors, assessed using the Attachment Q-Set (AQS). Participants were 121 mothers and their preschool children assessed in three samples (Portuguese sample, n ¼ 31; US Midwestern sample, n ¼ 38; US Southeastern sample, n ¼ 52). AQS and ASA assessments were completed approximately 1.5 years before the ASCT data were collected. No cross-sample contrasts for the attachment variables were significant. Correlations and structural equation modeling (SEM) indicated that the three attachment measures were significantly associated and that both maternal secure base script knowledge and children’s secure base behaviors (AQS) were uniquely and significantly associated with children’s mental representations of attachment (ASCT). A test of the indirect effect between maternal scripts and child representations through children’s secure base behaviors was not significant.
- Social competence in preschool children: Replication of results and clarification of a hierarchical measurement modelPublication . Santos, António José; Peceguina, Maria Inês Duarte; Daniel, João Rodrigo; Shin, Nana; Vaughn, Brian E.This study tested assumptions and conclusions reached in an earlier confirmatory factor analysis (CFA) study of the social competence (SC) construct for preschool children. Two samples (total N = 408; a new Portuguese sample and one from US samples that had participated in the original study) contributed data. Seven SC indicators were tested for mean differences across age, sex, and sample. Significant sex differences were found for peer acceptance (favoring girls) and for initiating affectively neutral interactions (boys had higher rates), and the sex by sample interaction also was significant for initiating interactions (i.e., effect significant only in the Portuguese sample). In CFAs, the hypothesized structure of SC fits the data and was invariant across sample and age within sample in both measurement and structural tests. The model was invariant at the measurement level for sex within sample tests, but not at the structural level. The results replicate and extend understandings of SC reported in the original study.
