- Affiliative sructures and social competence in portuguese preschool childrenPublication . Daniel, João Rodrigo; Santos, António José; Peceguina, Maria Inês Duarte; Vaughn, Brian E.The goal of this study was to determine whether peer social competence (SC), defined as the capacity to use behavioral, cognitive, and emotional resources in the service of achieving personal goals within preschool peer groups, was related to the type of affiliative subgroups to which children belonged. Two hundred forty Portuguese preschool children (152 seen in consecutive years of data collection) from middle-class families participated. Affiliative subgroup type was assessed from observed proximity data. Social competence was assessed using observational and sociometric measures. Children in more cohesive affiliative subgroups had higher levels of SC, whereas ungrouped children had the lowest SC scores. Follow-up analyses indicated that 2 of the measured SC domains (social engagement/motivation, profiles of behavior/personality attributes) were responsible for the overall difference in SC. Further, membership in a more cohesive subgroup in 1 year contributed to increases in scores for 2 of 3 SC domains (i.e., profiles of behavior/personality attributes and peer acceptance) in the following year. Results suggest that affiliative subgroups both reflect and support individual differences in peer SC during early childhood.
- Affiliative subgroups in preschool classrooms: Integrating constructs and methods from social ethology and sociometric traditionsPublication . Santos, António José; Daniel, João Rodrigo; Fernandes, Carla; Vaughn, Brian E.Recent studies of school-age children and adolescents have used social network analyses to characterize selection and socialization aspects of peer groups. Fewer network studies have been reported for preschool classrooms and many of those have focused on structural descriptions of peer networks, and/or, on selection processes rather than on social functions of subgroup membership. In this study we started by identifying and describing different types of affiliative subgroups (HMP- high mutual proximity, LMP- low mutual proximity, and ungrouped children) in a sample of 240 Portuguese preschool children using nearest neighbor observations. Next, we used additional behavioral observations and sociometric data to show that HMP and LMP subgroups are functionally distinct: HMP subgroups appear to reflect friendship relations, whereas LMP subgroups appear to reflect common social goals, but without strong, within-subgroup dyadic ties. Finally, we examined the longitudinal implications of subgroup membership and show that children classified as HMP in consecutive years had more reciprocated friendships than did children whose subgroup classification changed from LMP or ungrouped to HMP. These results extend previous findings reported for North American peer groups.
- Análise do fenómeno de base segura em contexto familiar: As relações criança/mãe e criança/paiPublication . Monteiro, Lígia Maria Santos; Veríssimo, Manuela; Vaughn, Brian E.; Santos, António José; Fernandes, MaríliaO estudo analisa, no contexto da teoria de Bowlby e Ainsworth, o modo como a criança utiliza as figuras parentais como base segura, explorando a especificidade da organização destes comportamentos nas duas relações. Analisa, ainda, a existência de semelhanças ou diferenças nas classificações da criança em relação à mãe e ao pai. Os participantes são 56 díades mãe/criança e pai/criança, tendo as crianças idades compreendidas entre os 29 e os 38 meses. Observadores independentes realizaram visitas domiciliárias com a criança/mãe e com a criança/pai, utilizando o AQS (Waters, 1995). Não foram encontradas diferenças significativas entre os valores de segurança para a mãe e para o pai. Com base nas escalas do AQS, obtiveram- se diferenças significativas na Proximidade e no Contacto Físico. Assim, a criança utiliza ambos os pais como base segura, embora os estilos de interacção possam apresentar características específicas. Verificou-se, ainda, a existência de uma correlação significativa entre os valores de segurança da criança em relação à mãe e ao pai, o que vai ao encontro dos resultados obtidos por Veríssimo et al. (2006). Esta correlação poderá ser explicada pela semelhança nos cuidados parentais. ------ ABSTRACT ------- This paper high lights the importance of a family system approach to the study of attachment, in a naturalistic environment, by analysing the way the child uses both mother and father as a secure base, as well as, the concurrence or independence of this attachment relationships. 56 mother/child and father/child díades participated in the study. Children’s ages range between 29 and 38 months. Independent observers, made home observations of the child with the mother and the child with the father, using the AQS (Waters, 1995). No differences were found between mean averages for security scores for mothers and fathers, showing that the child is able to use both parents as secure-bases. Significant differences were found in the Proximity and Physical Contact scales between both parents, suggesting that mothers and fathers probably have different communicative styles. A significant correlation was found between security scores for mother and father, a result comparable to the one obtained by Veríssimo et al. (2006). This could be explained by the similarity on parental caregiving behaviour.
- Assessing and quantifying the secure base script from narratives produced by preschool age children: justification and validation testsPublication . Vaughn, Brian E.; Posada, German; Verissimo, Manuela; Lu, Ting; Nichols, Olivia I.Building on aframework presented by Bretherton and associates, Waters and associates argued that interaction sequences relevant to children's access to and use of asecure base for exploration during infancy/toddlerhood become internalized as script-like representations. For adults, these scripted representations are readily assessed using word-prompt lists d to elicit attachment relevant narratives. However, this method is not appropriate during early childhood. Waters and associates used stories from Bretherton's Attachment Story Completion Task for this purpose. However, the method they used to score secure base script use is not efficient for larger samples (e.g. over 50), and new approaches for scoring have been designed. We describe two approaches to story selection and scoring for access to and use of the secure base script. The two scoring methods show substantial and significant overlap and also have significant associations with other methods of measuring attachment security during early childhood.
- 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.
- Children's representations of attachment and positive teacher–child relationshipsPublication . Veríssimo, Manuela; Torres, Nuno; Silva, Filipa; Fernandes, Carla; Vaughn, Brian E.; Santos, António JoséThis study was designed to explore whether children's representations of attachment contribute to the co-construction of positive teacher-child relationships. An assessment of verbal intelligence was included as a predictor on the assumption that teachers might perceive themselves as having better relationships with more verbally competent children. Participants were 52 children from two pre-schools, in the district of Lisbon. The Attachment Story Completion Task (ASCT) was used to assess children's attachment security. The PCV-P (a scale developed in portuguese language) was used to describe teacher-child relationships through teachers' ratings of child secure base behavior and emotion regulation and the Wechsler Preschool and Primary Scale of Intelligence (WPPSI-R) was used to access verbal skills. Bivariate correlations showed that the teachers' rating of child secure base behavior was significantly associated with both child attachment security and verbal IQ. In a multiple regression analysis, the overall model R2 was significant, as was the interaction term showing a moderating effect of attachment security on the relation between verbal IQ and teachers' ratings of secure base. The results suggest that co-construction of a close attachment-relevant relationship with teachers in early childhood is, in part, a function of the security in the context of parent-child attachment, but also of child verbal development.
- Co-evolution of friendships and antipathies: A longitudinal study of preschool peer groupsPublication . Daniel, João Rodrigo; Santos, António José; Antunes, Marta Justino Ferrúcio; Fernandes, Marília; Vaughn, Brian E.We used stochastic actor-based models to test whether the developmental dynamics of friendships and antipathies in preschool peer groups (followed throughout three school years) were co-dependent. We combined choices from three sociometric tasks of 142 children to identify friendship and antipathy ties and used SIENA to model network dynamics. Our results show that different social processes drive the development of friendship and antipathy ties, and that they do not develop in association (i.e., friendship ties are not dependent on existing antipathies, and vice-versa). These results differ from those of older children (age range = 10-14) suggesting that the interplay of friendship and antipathy only plays a significant role in the peer group context in older children. We propose these differences to be likely related with preschool age children's inaccurate perceptions of their classmates' relationships, particularly of their antipathies, and/or with the absence of shared norms to deal with antipathetic relationships.
- 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.
- Coordenação entre o modelo dinâmico interno da mãe e o comportamento de base segura dos seus filhosPublication . Verissimo, Manuela; Monteiro, Lígia Maria Santos; Vaughn, Brian E.; Santos, António José; Waters, Harriet S.A correspondência entre as representações de vinculação maternas e os comportamentos de base segura da criança são explorados numa amostra de díades mãe/criança portuguesas. Os scripts de base segura maternos foram avaliados utilizando um instrumento, recentemente criado, as Narrativas de Representação da Vinculação em Adultos, que consiste num conjunto de palavras que visa que as mães contem histórias com conteúdos relevantes para a vinculação. O Attachment QSet (realizado por observadores) foi utilizado para avaliar os comportamentos de base segura das crianças. Os valores para as narrativas de base segura maternas são internamente consistentes (os alphas de Cronbach encontram-se todos acima de .80). O compósito das narrativas de base segura maternas encontra-se significativa e positivamente correlacionado com o valor de segurança das crianças no AQS. Estas análises indicam que mães com narrativas nas quais o script de base segura esta presente têm crianças que as tratam como bases seguras, em observações realizadas em casa. Os resultados deste estudo sugerem que o elemento central dos modelos internos de vinculação é a existência e acessibilidade a um script de base segura. Resultados adicionais, indicam que as traduções das narrativas, nomeadamente, para inglês podem receber valores válidos e fiáveis, mesmo quando não cotadas por nativos da língua.
