Patterns of emotion regulation at two years of age: associations with mothers’ attachment in a fear eliciting situation

Cumulative stress, PTSD, and emotion dysregulation during pregnancy and epigenetic age acceleration in Hispanic mothers and their newborn infants

Pregnancy can exacerbate or prompt the onset of stress-related disorders, such as post-traumatic stress disorder (PTSD). PTSD is associated with heightened stress responsivity and emotional dysregulation, as well as increased risk of chronic disorders and mortality. Further, maternal PTSD is associated with gestational epigenetic age acceleration in newborns, implicating the prenatal period as a developmental time period for the transmission of effects across generations. Here, we evaluated the associations between PTSD symptoms, maternal epigenetic age acceleration, and infant gestational epigenetic age acceleration in 89 maternal-neonatal dyads. Trauma-related experiences and PTSD symptoms in mothers were assessed during the third trimester of pregnancy. The MethylationEPIC array was used to generate DNA methylation data from maternal and neonatal saliva samples collected within 24 h of infant birth. Maternal epigenetic age acceleration was calculated using Horvath's multi-tissue clock, PhenoAge and GrimAge. Gestational epigenetic age was estimated using the Haftorn clock. Maternal cumulative past-year stress (GrimAge: p = 3.23e-04, PhenoAge: p = 9.92e-03), PTSD symptoms (GrimAge: p = 0.019), and difficulties in emotion regulation (GrimAge: p = 0.028) were associated with accelerated epigenetic age in mothers. Maternal PTSD symptoms were associated with lower gestational epigenetic age acceleration in neonates (p = 0.032). Overall, our results suggest that maternal cumulative past-year stress exposure and trauma-related symptoms may increase the risk for age-related problems in mothers and developmental problems in their newborns.

Verbal - prosodic association when narrating early caregiving experiences during the adult attachment interview: differences between secure and dismissing individuals

Previous studies reported an inconsistency between verbal extracts and emotional physiological activation in dismissing individuals when narrating their early caregiving experience at the Adult Attachment Interview (AAI). This study aimed to explore this discrepancy by analyzing the degree of concordance between verbal content and prosodic characteristics, index of physiological activation, when dismissing and secure individuals discuss negative childhood memories during the AAI. Results showed that secure participants presented a high coherence between verbal content and emotional activation, as expressed by prosody, revealing a reprocess of negative experiences that is the core feature of the development of secure working models. In contrast, dismissing participants' prosodic characteristics were discrepant with the verbal content. These individuals downplayed the nature and impact of negative experiences and emotions, but used a prosody that revealed a high emotional arousal. The difference between the two groups was more evident for participants who had experienced more rejecting parents.

Pathways to social-emotional functioning in the preschool period: The role of child temperament and maternal anxiety in boys and girls

Individual differences in social-emotional functioning emerge early and have long-term implications for developmental adaptation and competency. Research is needed that specifies multiple early risk factors and outcomes simultaneously to demonstrate specificity. Using multigroup longitudinal path analysis in a sample of typically developing children (N = 541), we examined child temperament dimensions (surgency, negative affectivity, and regulation/effortful control) and maternal anxiety in infancy and age 2 as predictors of child externalizing, internalizing, dysregulation, and competence behaviors at age 3. Four primary patterns emerged. First, there was stability in temperament dimensions and maternal anxiety from infancy to age 3. Second, negative affectivity was implicated in internalizing problems and surgency in externalizing problems. Third, effortful control at age 2 was a potent mediator of maternal anxiety in infancy on age 3 outcomes. Fourth, there was suggestive evidence for transactional effects between maternal anxiety and child effortful control. Most pathways operated similarly for boys and girls, with some differences, particularly for surgency. These findings expand our understanding of the roles of specific temperamental domains and postnatal maternal anxiety in a range of social-emotional outcomes in the preschool period, and have implications for efforts to enhance the development of young children's social-emotional functioning and reduce risk for later psychopathology.

Estrategias de regulación emocional materna con bebés en situaciones de estrés: el uso del canto materno

El propósito de este estudio fue caracterizar las estrategias regulatorias empleadas por madres en la interacción con sus bebés durante el primer año de vida en las situaciones de estrés que ocurrían en el contexto natural (hogar) de cuidado diario. Así mismo, determinar si el canto materno cumplía una función regulatoria de los estados fisiológicos y emocionales del bebé. Se utilizó un diseño de investigación no experimental de tipo transversal, con una muestra no probabilística por conveniencia de 32 díadas madre-bebé, que pertenecían a estratos socioeconómicos bajos. Los hallazgos de este estudio permitieron establecer dos patrones de cuidado materno: Patrón Regulatorio Contingente y Patrón Regulatorio Poco/No Contingente. También, se pudo identificar que el canto materno cumple, entre otras, una función regulatoria en situaciones de estrés en las rutinas de cuidado cotidiano.
