Background: Oxytocin (OXT) has attracted research interest for its potential involvement in many of the behavioural problems observed in childhood. Due to its logistical advantages, saliva is an attractive fluid to quantify neuropeptides in children. Salivary OXT has been suggested as a potential biomarker for psychopa- thology during childhood. However, several questions still remain about the extent to which,...
Children acquire and develop emotional regulatory skills in the context of parent-child attachment relationships, nonetheless empirical studies have focused mainly on mother and less information is available regarding the role of both parent-child attachment relationships. Furthermore, despite its importance, there is no information regarding preschool years. This study aims to fill this gap by exploring the po...
Correlated trait–correlated method minus one was used to evaluate convergent and discriminant validity of Social Competence Behavior Evaluation questionnaire (Social Competence, Anger-Aggression, Anxiety-Withdrawal) between multiple raters. A total of 369 children (173 boys and 196 girls; Mage = 55.85, SDage = 11.54) were rated by their mothers, fathers, and teachers. Results showed more convergence between par...
Using a sample of Portuguese pre-school age children, we aimed to identify different play profiles based on teachers' descriptions of social and non-social behaviors; as well as characterize them in terms of children's characteristics (sex and temperament), and fathers' parenting styles (e.g. warmth and involvement or punitive strategies). The 243 children were distributed across four profiles (identified throu...
The main goal of this study was to explore the contributions of early father-child and mother-child attachment relationships to children’s later social competence with their preschool peers; possible unique and shared contributions were tested. Using a multi-method design and focusing on direct observation, attachment was assessed at home at age 3 with the Attachment Behavior Q-sort (AQS) and two years later so...
Although peer conflict is a common event in preschool classrooms, few studies have examined relations between coping with peer conflict and social competence (SC) in preschool samples. In this study, 166 preschoolers (95 male) were observed during dyadic play episodes designed to induce a resource-based conflict. Coping tactics were coded using Zimmer-Gembeck and Skinner’s (2011) taxonomy and were evaluated in ...
This 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 inter- views were assessed using both variable-centered and person-centered approaches (N 1453, 696 girls) in 4 sam...
Data from a national sample of Portuguese preschool centers were used to examine the relationship between age of start and number of hours in child care and levels of externalizing and prosocial behaviors with peers. Participants were both parents and teachers of 543 children (mean age = 4.5 years, 50.6% girls). Children started child care between 3 and 64 months and were attending child care 1–9 hr per day. Th...
