Skin-to-Skin Contact at Birth for Very Preterm Infants and Mother-Infant Interaction Quality at 4 Months: A Secondary Analysis of the IPISTOSS Randomized Clinical Trial.

Importance: Good-quality parent-infant interactions have protective effects on infant socio-emotional and behavioral development. These interactions are especially critical for very preterm infants at risk of vulnerabilities related to immaturity. Skin-to-skin contact (SSC) has been found to improve mother-preterm infant interaction behaviors, but few studies exist regarding its benefits when initiated immediately after birth. Objective: To determine the effect of immediate SSC at birth for very preterm infants on mother-infant interaction quality at 4 months of corrected age. Design, Setting, and Participants: This secondary analysis used data from the Immediate Parent-Infant Skin-to-Skin Study (IPISTOSS), a randomized clinical trial conducted between April 1, 2018, and June 30, 2021, at 3 neonatal units in Sweden and Norway. Participants included very preterm infants (28-33 gestational weeks of age) and their parents. Four-month follow-up was concluded in December 2021. Data analyses were performed on March 16 and September 18, 2023. Intervention: Infants were allocated to standard incubator care or SSC with either parent initiated at birth and continued throughout the first 6 hours after birth. Main Outcomes and Measures: The primary outcome was mother-infant interaction quality as measured with the Parent-Child Early Relational Assessment (PCERA), based on video recordings of a 5-minute free-play situation with mother-infant dyads at 4 months of corrected age. A multilevel regression analysis was performed. Results: This analysis included 71 infants (31 twins [44%]) and 56 mothers. Infants had a mean (SD) gestational age of 31 weeks 3 (1.3) days, and more than half were male (42 [59%]); mothers had a mean (SD) age of 32 (4.9) years. There were 37 infants allocated to standard care and 34 to SSC with either parent after birth. During the first 6 hours after birth, fathers provided more SSC than mothers, with a median (IQR) of 3.25 (2.25-4.5) and 0.75 (0-2.5) hours, respectively. A statistically significant difference in 1 of 5 PCERA subscales (subscale 3: infant positive affect, communicative and social skills) was observed, with higher-quality mother-infant interaction in the SSC group at 4 months (Cohen d = 0.67 [95% CI, 0.17 to 1.17]; P = .01). This effect remained significant when adjusting for primiparity, child sex, and observation setting. Conclusions and Relevance: In this study of the effect of immediate parent-infant SSC after very preterm birth, SSC was beneficial for the mother-infant relationship. These findings suggest that immediate SSC should be supported in the clinical setting. Trial Registration: ClinicalTrials.gov Identifier: NCT03521310.

Parental Coping, Representations, and Interactions with Their Infants at High Risk of Cerebral Palsy.

The aim of this study is to describe parental coping, representations, and interactions during the time of inclusion in the Small Step early intervention program for infants at high risk of cerebral palsy (CP) in Norway (ClinicalTrials.gov: NCT03264339). Altogether, 11 infants (mean age 4.8 months, SD: 1.5) and their parents (mothers: n = 10, fathers: n = 9) were included. Parental coping was assessed using the Parenting Stress Index-Short Form (PSI-SF) and the Hospital Anxiety and Depression Scale (HADS). Parental representations and parent-infant interactions were assessed using the Working Model of the Child Interview (WMCI) and the Parent-Child Early Relational Assessment (PCERA). Parents' PSI-SF and HADS scores were within normal range; however, 26.7% showed symptoms of stress, 52.6% showed symptoms of anxiety, and 31.6% showed symptoms of depression above the cut-off. WMCI results indicate that 73.7% of the parents had balanced representations. For PCERA, the subscale Dyadic Mutuality and Reciprocity was of concern, while two other subscales were in areas of strength and three subscales in some concern areas. There were no differences between mothers and fathers. Most of the parents had balanced representations, some had mental or stress symptoms and many were struggling with aspects of the parent-infant interaction. This knowledge could be useful when developing more family-centered interventions.

Fathers' prenatal attachment representations and the quality of father-child interaction in infancy and toddlerhood.

Despite the strong evidence that fathers have a crucial role in child well-being, very little is known about the development of the father-child relationship from prenatal to postnatal period. In this longitudinal study, the fathers' prenatal attachment representations (n = 129), between 29 and 32 gestational weeks, were assessed with the Working Model of Child Interview, and the father-child interaction was analyzed with the Parent-Child Early Relational Assessment at 4 and 18 months after the birth. The results showed that fathers' prenatal balanced attachment representations were associated with more positive paternal behaviors compared to fathers with disengaged attachment representations when the child was 4 months old, but not when the child was 18 months old. In addition, positive changes occurred in the interaction quality between 4 and 18 months in all three groups of representation categories (balanced, disengaged, distorted), which offers an optimistic view of the evolving nature of the father-child relationship.

The Paternal Brain in Action: A Review of Human Fathers' fMRI Brain Responses to Child-Related Stimuli.

As fathers are increasingly involved in childcare, understanding the neurological underpinnings of fathering has become a key research issue in developmental psychobiology research. This systematic review specifically focused on (1) highlighting methodological issues of paternal brain research using functional magnetic resonance imaging (fMRI) and (2) summarizing findings related to paternal brain responses to auditory and visual infant stimuli. Sixteen papers were included from 157 retrieved records. Sample characteristics (e.g., fathers' and infant's age, number of kids, and time spent caregiving), neuroimaging information (e.g., technique, task, stimuli, and processing), and main findings were synthesized by two independent authors. Most of the reviewed works used different stimuli and tasks to test fathers' responses to child visual and/or auditory stimuli. Pre-processing and first-level analyses were performed with standard pipelines. Greater heterogeneity emerged in second-level analyses. Three main cortical networks (mentalization, embodied simulation, and emotion regulation) and a subcortical network emerged linked with fathers' responses to infants' stimuli, but additional areas (e.g., frontal gyrus, posterior cingulate cortex) were also responsive to infants' visual or auditory stimuli. This review suggests that a distributed and complex brain network may be involved in facilitating fathers' sensitivity and responses to infant-related stimuli. Nonetheless, specific methodological caveats, the exploratory nature of large parts of the literature to date, and the presence of heterogeneous tasks and measures also demonstrate that systematic improvements in study designs are needed to further advance the field.
