    Socioemotional development is central throughout life, and it unfolds in an interpersonal context in which each significant caregiver has an impact, particularly during infancy. However, only a relatively small number of studies have investigated associations between mothers and fathers' personality and emotional characteristics with their infant's socioemotional development during the perinatal period. Therefore, the present article examines the relationship between maternal and paternal personality traits and emotion regulation difficulties during the prenatal period with offspring's socioemotional development. This was a non-experimental and longitudinal study that included a community sample of 55 mother-father-baby triads. Parental assessments were carried out between the second and third trimester of pregnancy, and baby's socio-emotional development was assessed during their 2nd month after birth. Results evidenced differences between maternal and paternal personality traits and emotion regulation difficulties during the perinatal period as well as distinct contributions on 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.
