    Early interventions and parenting programs have been found to be the most effective interventions in promoting wellbeing and preventing difficulties during childhood and adulthood, mainly because they operate in a sensitive period. Mentalization-based and video feedback interventions have shown their effectiveness in caregiver-child relationships. This study aimed to analyze the effect of a preventive mentalization-based intervention with video feedback on a group of Chilean mothers of preschool children compared with a control group. Fifthy mothers were assessed at baseline and at followup. Results showed that mothers of the experimental group reached lower levels of maternal stress and higher use of mental language, and that their children showed lower risk in their socio-emotional development.

    Parental personality traits and emotion regulation difficulties: their relationship with early triadic interactions and infant’s socioemotional development
    (2024) Muzard Costa, Antonia María; Olhaberry Huber, Marcia; Pontificia Universidad Católica de Chile. Escuela de Psicología
    Background: socioemotional development is a pivotal aspect of human life, particularly during infancy, and is intricately woven within the personal and interpersonal dynamics of caregiver- infant interactions. This longitudinal study represents a pioneering exploration into the associations between mothers’ and fathers’ personality traits, emotion regulation difficulties, triadic interactions, and infants’ socioemotional development during the perinatal period. Objective: The primary objective was to investigate the complex interplay between parental personality traits and emotion regulation difficulties in mother-father-baby triads with its impact on early triadic interactions and infants’ socioemotional development. Methods: In this non-experimental, longitudinal study, 55 Chilean mother-father-baby triads were assessed from pregnancy until infant’s sixth month after birth. Additionally, parental levels of personality functioning, relationship satisfaction, depressive symptomatology and childhood adverse experiences were considered as potential covariables. Results: Findings revealed that maternal and paternal attributes have particular predictive values and exert distinct influences on both triadic interactions as well as infant’s socioemotional development from pregnancy until infants’ 6-months postpartum. Notably, maternal emotionality and paternal agreeableness, as well as both significant caregiver’s emotion regulation difficulties emerged as significant factors when fostering collaborative triadic interactions and enhancing infant’s socioemotional development. Additionally, when cofounding variables were included, maternal depressive symptomatology emerged as a significant predictor of infant’s socioemotional difficulties at 6-months postpartum. Moreover, the study highlights the moderating role of triadic interactions, emphasizing their significance in influencing the relationship between maternal emotion regulation difficulties and infant’s socioemotional development. Discussion: This research stresses the need for a comprehensive longitudinal perspective in understanding the impact of significant caregivers’ characteristics upon early triadic interactions and infant’s socioemotional development. Therefore, it acknowledges the unique dynamics of the perinatal period, while considering the individualities within each family triad which is crucial for unraveling the complexities inherent in the intricate fabric of family relationships and infant’s socioemotional development.

    The role of mentalization in a video-feedback intervention: a case study of a mother-infant dyad with depressive symptomatology
    (2025) Morán Kneer, Javier; Sieverson, Catalina; Olhaberry Huber, Marcia; Costa Cordella Satefanella; Honorato, Carolina; Muzard Costa, Antonia María; Leyton, Fanny; León, María José; García Bravo, Nataly; Arredondo Guerrero, Kathya; Olivares García, Stefania; Garay Contreras, Camila; Alvarado Quiroz, Valentina
    This single-case longitudinal study examined changes in therapist and patient mentalization over five video-feedback sessions with a mother experiencing postpartum depression. Using qualitative and observational coding, the study analyzed the moment-to-moment evolution of mentalization within therapeutic interactions. The intervention assessed both therapist and patient mentalization, identifying three core themes related to the therapeutic process. Video-feedback contributed to increased maternal mentalization, fostering a more accurate perception of the infant’s needs and emotional states. Improvements in maternal mentalization were associated with reduced anxiety and self-doubt, greater sensitivity, and enhanced attachment behaviors. The participant also reported decreased depressive symptoms and greater confidence in interacting with her infant. Findings indicate that video-feedback provides a structured and reflective space for mothers to observe, interpret, and regulate their caregiving behaviors through guided self-observation and therapeutic scaffolding. These results underscore the role of video-feedback in enhancing mentalization within mother-infant psychotherapy, offering a promising intervention for addressing postpartum depression-related caregiving difficulties. While findings highlight its potential to bridge the gap between perceived and actual caregiving behaviors, further research is needed to examine its mechanisms of change, long-term impact, and clinical applicability.
