Introduction: Family resilience can be defined as the capacity of the family system to resist and recover from stressful life challenges (Walsh, 2016). Past research shows that several factors influence parental perception of family resilience, including parent-child interaction, parental depression and the interparental relationship. There is a lack of research on family resilience in the global south, especially in remote areas. The aim of this study is to understand the family resilience, measured using the adapted and validated version of Family Hardiness Index (FHI) (dos Santos Silva et al., in press), of families living along the rivers, in the Amazon region and the factors involved in its perception by mothers and fathers. This is a vulnerable population with low human development index and few public policies. This study is part of a larger project on family functioning and the child’s emotion regulation in course.

Methods: Until now, 27 families living in the islands close to the city of Belém, in the north of Brazil, were visited and both mother and father answered to the FHI and other instruments. Parents were also observed interacting with their children in dyads (M-C and F-C) and triad (M-F-C). The children were between 3 and 5 years old.

Results: Preliminary results revealed that mothers obtained higher scores than fathers in the total score and in the two dimensions of the FHI validated version: 1) commitment and challenge and 2) control and confidence. Non-parametric t-tests revealed significant statistical differences between mothers and fathers in the total score (p=.03) and in the control and confidence dimension (p=.05) suggesting that mothers have a greater family's sense of being in control of family life rather than being shaped by outside events and circumstances than fathers. Further analyses will help identify the factors involved in the perception of family resilience.

Introduction: Family resilience is characterized by the ability to cope with stress. Positive interactions may facilitate the transmission of resilience between family members. This can be observed through biobehavioral synchrony as family members who synchronize with one another can regulate their emotions and handle daily stressors. However, synchrony, being rooted in the interactions, may vary based on the attachment profile of family members. In fact, pioneers of attachment stipulate that a secure attachment promotes a healthy development in children as well as a positive interaction with the environment. We hypothesize that anxious attachment is associated with more synchrony due to its hypervigilance and intrusive nature. Whereas avoidant attachment is associated with less synchrony due to the inhibition of negative emotions. Therefore, a certain level of anxious attachment would foster positive interactions to compensate from stress. Which in turn, would help family members synchronize, allowing them to strengthen their bonds and face daily hassles while being resilient.

Methods: A total of 55 triadic families participated in a stress-induced task where participants had to build tangrams, where one of the paradigms was impossible to solve. Behavioral synchrony was assessed through coding, resilience was assessed via physiological measures by attaching electrodes on the participants to observe heart rate variability (HRV) and attachment was measured via scales that participants completed before the lab session.

Results: Based on the two attachment dimensions (avoidant-anxious), a mediation analysis will be conducted to assess how attachment can be associated with synchrony. And how synchrony would then be associated with more resilient. After the stressful task, HRV will be assessed to evaluate whether participants were able to recover from the task or not which in turn, will indicate how resilient each group is.

Introduction: The quality of mother-father-infant interactions, conceptualized in terms of family alliance, is known to influence infants’ socioemotional functioning. It has been shown that this influence can be observed at a physiological level, through the measure of vagal tone. Family alliance can be classified into three categories, each with its own characteristics: cooperative, conflictual, and disordered. The present study investigates the differences in infants’ physiological regulation during family interaction according to the category of family alliance.

Methods: 84 mother-father-infant triads participated in laboratory visits when the infant was 3 months of age. Parents were asked to play together with their infant as follows: 1) one parent plays with the infant, 2) parents switch roles, 3) parents play together with the infant, 4) parents have a discussion next to the infant. Infant’s ECG was recorded to obtain the Root Mean Square of Successive Differences (RMSSD), an indicator of vagal tone. Family alliance was assessed through observation of interactive behaviors.

Result: Results of known class Latent Profile Analysis (LPA) showed differences in infants’ RMSSD according to the family alliance category. Compared to cooperative family alliances, infants from disordered family alliances showed significantly lower RMSSD during most of the interaction. Infants from conflictual family alliances had significantly lower RMSSD only during the triadic interaction, and marginally during the discussion between the parents.

Conclusion: This study underlines the influence of family alliance on infants’ physiological regulation. Infants in disordered family alliances showed an overall lower vagal tone, suggesting poorer physiological regulation, whereas infants in conflictual family alliances showed lower vagal tone only in the presence of both parents. The results are in line with previous studies showing that the impact of conflict in families does not necessarily impair individual parenting behaviors, but rather the way parents can coordinate together when interacting with the infant.

Introduction: Joint attention (JA) is a form of human information processing (Mundy & Newell, 2007) that involves the shared focus of two individuals on an object or event. Classically, its development has been linked to the emergence of social cognition (Bretherton, 1991). However, this social-cognitive model of JA doesn’t allow to account for the wide range of individual differences in the first two years of life (Mundy et al., 2007). An alternative model suggests that the development of JA involves the integration of multiple processes (Mundy & Vaughan, 2008), whose role needs to be further investigated. Moreover, while most studies examining JA employed cross-sectional designs, there is a paucity of longitudinal research exploring its developmental trajectories.

Methods: The aim of this study is twofold. First, we examine the developmental trajectories of JA, measured at 9, 12, and 15 months during structured interaction with an experimenter (ESCS; Mundy et al., 2003). Second, we investigate correlates and precursors of JA at 3, 6, 9, 12, and 15 months across 5 domains evaluated with the GMDS-R (Griffiths et al., 1996): locomotor development, eye and hand coordination, language and communication, personal-social, and non-verbal cognitive skills.

Analytic Strategy: We will use multilevel modeling to examine the individual growth trajectories of JA. Structural equation modeling will be employed to explore the concurrent and longitudinal associations between JA and the motor, visual-motor, linguistic, social, and cognitive domains, with each domain being treated as a latent variable measured at multiple time points. Results will be presented and discussed at the conference.

Implications: Identifying the factors underlying individual differences in the development of infant joint attention has implications for clinical practice, including implementation and advancements of screenings and interventions for typical and atypical development, aimed at promoting healthy socio-emotional development and well-being in young children.
