Maternal prenatal mood problems and lower maternal emotional availability associated with lower quality of child's emotional availability and higher negative affect during still-face procedure

Our aim was to study the effects of maternal perinatal mood and maternal emotional availability on child emotional availability and negative affect during the still-face procedure (SFP). The sample included 214 women who participated in a prospective study. We assessed maternal mood problems using the Mini International Neuropsychiatric Interview and PRAQ questionnaire during pregnancy and using STAI and EPDS questionnaires during pregnancy and at 6 months after delivery. Maternal and child emotional availability were studied using the Emotional Availability Scales during the SFP at 6 months. We observed and quantified child's negative affect during SFP episodes. We found that mothers with maternal mood problems (anxiety and/or depression) during pregnancy, but not postnatally, showed less optimal maternal structuring during the SFP, and the children showed lower involvement and responsiveness during interactions with their mothers. Furthermore, lower maternal emotional availability was related to the child's higher negative affect during the SFP. Our findings underline the independent roles of both prenatal stress exposure and maternal caregiving behavior in a child's socioemotional development.     

Maternal Lifetime Trauma Exposure,Prenatal Cortisol,and Infant Negative Affectivity

Little research has examined the impact of maternal lifetime trauma exposure on infant temperament. We examined associations between maternal trauma history and infant negative affectivity and modification by prenatal cortisol exposure in a sociodemographically diverse sample of mother–infant dyads. During pregnancy, mothers completed measures of lifetime trauma exposure and current stressors. Third‐trimester cortisol output was assessed from maternal hair. When infants were 6 months old, mothers completed the Infant Behavior Questionnaire‐Revised. In analyses that controlled for infant sex and maternal age, education, race/ethnicity, and stress during pregnancy, greater maternal trauma exposure was associated with increased infant distress to limitations and sadness. Higher and lower prenatal cortisol exposure modified the magnitude and direction of association between maternal trauma history and infant rate of recovery from arousal. The association between maternal trauma history and infant distress to limitations was somewhat stronger among infants exposed to higher levels of prenatal cortisol. The analyses suggested that maternal lifetime trauma exposure is associated with several domains of infant negative affectivity independently of maternal stress exposures during pregnancy and that some of these associations may be modified by prenatal cortisol exposure. The findings have implications for understanding the intergenerational impact of trauma exposure on child developmental outcomes.     

The effect of the COVID-19 pandemic on infant development and maternal mental health in the first 2 years of life

We investigated how exogenous variation in exposure to the COVID-19 pandemic during the first year of life is related to infant development, maternal mental health, and perceived stress. Ninety-three socioeconomically diverse pregnant women were recruited before the pandemic to participate in a longitudinal study. Infants ranged in age at the beginning of lockdown (0–9.5 months old), thus experiencing different durations of pandemic exposure across the first year of life. The duration of pandemic exposure was not associated with family demographic characteristics, suggesting it captured exogenous variability. We tested associations between this exogenous variation in pandemic exposure and child and family outcomes. We also examined whether mother-reported disruptive life events were correlated with child and family outcomes. We found no association between duration of pandemic exposure in the first year of life and infant socioemotional problems, infant language development, or maternal mental health and perceived stress symptoms, at 12 or 24 months. However, we found that self-reported exposure to pandemic-related disruptive life events predicted greater maternal depression, anxiety, and perceived stress at 12 months, and greater depression and anxiety at 24 months. Socioeconomic status did not moderate these associations. These findings suggest cautious optimism for infants raised during this period.     

A Longitudinal Examination of Physiological Regulation in Cocaine‐Exposed Infants Across the First 7 Months of Life

This study examined the association between prenatal exposure to cocaine and physiological regulation across the first 7 months of age. Measures of respiratory sinus arrhythmia (RSA) were obtained from 169 (82 cocaine‐exposed and 87 nonexposed) infants during baseline periods at 1 month and 7 months of age and during tasks designed to elicit positive and negative affect at 7 months of age. After controlling for maternal age, gestational age, and obstetrical risk, structural equation modeling indicated that the association between prenatal exposure to cocaine and baseline RSA at 7 months of age was direct even in the presence of an indirect effect through baseline RSA at 1 month of age. There were no indirect effects through maternal affect during mother‐infant interactions assessed at 1 month of age. Analyses also indicated a direct association between prenatal exposure to cocaine and RSA regulation to negative affect at 7 months of age.     

Mother-infant emotional availability through the COVID-19 pandemic: Examining continuity,stability, and bidirectional associations

The COVID-19 pandemic may impact the development of infants' social communication patterns with their caregivers. The current study examined continuity, stability, and bidirectional associations in maternal and infant dyadic Emotional Availability (EA) before and during the COVID-19 pandemic. Participants were 110 Israeli mother-infant dyads (51% girls) that were assessed prior to (Mage = 3.5 months) and during (Mage = 12.4 months) the pandemic. At both time points, mother-infant interactions were observed during play (nonstressful context) and tasks designed to elicit infant frustration (stressful context). Maternal and child EA were coded offline. Maternal EA demonstrated no significant mean-level changes from before to during the COVID-19 pandemic, whereas infant responsiveness and involvement increased over time. Stability and bidirectional associations in EA differed by context and were evident only in the stressful context. Mothers' perceived levels of social support further moderated these associations. Specifically, infants' pre-pandemic responsiveness and involvement predicted maternal EA during the pandemic only when mothers reported low levels of social support. Our findings suggest that maternal and child EA were not adversely impacted by the COVID-19 pandemic. However, patterns of EA demonstrated moderate-to-no stability over time, suggesting considerable individual differences in trajectories of EA.     

Patterns of positivity: Positive affect trajectories among infants of mothers with a history of depression

This study examined positive affect (PA) trajectories over the first year of life among infants of mothers with a history of depression (N = 191) as well as predictors (i.e., maternal prenatal and postpartum depression symptoms, maternal parenting behaviors) of those trajectories. Infant PA was observed in play and feeding tasks during laboratory visits at 3, 6, and 12 months of age; parenting behaviors were observed at 3 months. Mothers completed questionnaires regarding their symptoms of depression throughout the prenatal period and during the first 3 months postpartum. Growth curve analyses indicated that infant PA increased across time, and this finding replicated across both the play and feeding tasks, though increases slowed over time. Neither maternal prenatal nor postpartum depression symptoms predicted infants' PA trajectories, but mothers' PA, positive parenting, and disengaged parenting were associated with infant PA during the play task. Our finding that infant PA increased over the first year postpartum suggests PA trajectories among infants of mothers with a history of depression may be indices of resilience, despite risks associated with their mothers' history of depression. Furthermore, this study highlights parenting behaviors that may be important targets of prevention and early intervention efforts to bolster infant PA.     

Physiological Regulation at 9 Months of Age in Infants Prenatally Exposed to Cigarettes

The primary purpose of this study was to examine the association between prenatal cigarette exposure and physiological regulation at 9 months of age. Specifically, we explored the possibility that any association between prenatal cigarette exposure and infant physiological regulation was moderated by postnatal environmental tobacco smoke (ETS) exposure or infant gender. We evaluated whether male infants with prenatal cigarette exposure or infants who were also exposed to ETS after birth had the highest levels of physiological dysregulation. Respiratory sinus arrhythmia (RSA) was obtained from 206 (142 exposed and 64 nonexposed) infants during a baseline period and during procedures designed to elicit both positive and negative affect. There was a significant suppression of RSA during the negative affect task for nonexposed infants, but not for exposed infants. Postnatal ETS exposure did not moderate this association; however, gender did moderate this association such that boys with prenatal cigarette exposure had a significant increase in RSA rather than the suppression seen among both nonexposed boys and girls. These results provide additional support for the idea that boys are particularly vulnerable to the effects of prenatal cigarette exposure.     

The Regulation of Infant Negative Emotions: The Role of Maternal Sensitivity and Infant‐Directed Speech Prosody

This study explored the role of maternal sensitivity and infant‐directed speech (IDS) prosody in infants’ expression and regulation of negative emotion. Seventy mothers and their 3‐month‐old infants were observed during the Still‐Face Paradigm (SFP). Maternal sensitivity and IDS prosody were assessed at baseline and infant negative affect in the baseline, still‐face, and reunion episodes. Results showed that prototypical IDS prosody characterized by wider fundamental frequency (F0) variability was related to decreases in infant's negative affect, but only if accompanied by maternal sensitivity. Infants of sensitive mothers who spoke with more prototypical IDS prosody showed better abilities to regulate negative affect during the SFP. When prototypical IDS prosody was accompanied by low maternal sensitivity, infants showed lower regulation of negative emotions. In conclusion, infant negative affect regulation in a dyadic setting is facilitated by an optimal combination of both more prototypical maternal IDS prosody and maternal sensitive responsiveness. Implications for the study of mother–infant interaction are discussed.     

Developmental Trajectories of Emotion Regulation Across Infancy: Do Age and the Social Partner Influence Temporal Patterns

The ability to effectively regulate emotions is a critical component of early socio‐emotional development. This longitudinal study examined the developmental trajectories of emotion regulation in a sample of 3‐, 5‐, and 7‐month‐olds during an interaction with mothers and fathers. Infants' negative affect and use of behavioral strategies, including distraction, self‐soothing, and high intensity motor behaviors were rated during the still‐face episode of the Still‐Face Paradigm. Longitudinal mixed‐effects models were tested to determine whether strategies were followed by an increase or decrease in negative affect. Results from mother‐infant and father‐infant dyads indicated that focusing attention away from the unresponsive parent and engaging in self‐soothing behaviors were associated with a subsequent decline in negative affect and the strength of these temporal associations were stable across infancy. In contrast, high‐intensity motor behaviors were followed by an increase in negative affect and this effect declined over time. No significant effects were found for the behavioral strategy of looking at the parent. Results underscore the importance of considering infant age and the social partner when studying the effectiveness of emotion regulatory strategies in early infancy.     

Infant Affect During Parent—Infant Interaction at 3 and 6 Months: Differences Between Mothers and Fathers and Influence of Parent History of Depression

Fifty families participated in mother‐infant and father‐infant still‐face interaction at infant ages 3 and 6 months as part of a study of affect in early parent‐infant relationships. Infants' positive and negative affect and parents' positive affect and physical play were coded from videotapes. Consistent with previous research, during the normal condition, mothers displayed more positive affect than did fathers, and fathers were more likely than mothers to display physical play. Infants were more positive with mothers than with fathers. Parents' positive affect but not parent gender predicted infants' positive affect at 6 months. During the still‐face condition, infants of parents with a lifetime history of depression were more likely to display negative affect and less likely to display positive affect than infants with no such parent history. Infants' affect was unrelated to parents' current level of depressive symptoms, which indicates the value of considering family history of psychopathology when examining individual differences in infants' affect.     

Adolescent Fathers' Parenting Stress,Social Support,and Involvement with Infants

The present study examined the relationship between concurrent measures of adolescent fathers' parenting stress, social support, and fathers' care‐giving involvement with the 3‐month‐old infant, controlling for fathers' prenatal involvement. The study sample consisted of 50 teenage father–mother dyads. Findings from multivariate regression revealed that fathers' parenting stress was significantly and negatively related to fathers' care giving as perceived by both fathers and mothers. The relationship between support for father involvement provided by the young man's parents and father reported care‐giving involvement approached significance. Social support from both teenagers' parents buffered the negative influence of parenting stress on fathers' involvement with the baby. Policy and intervention implications are discussed.     

Maternal Cocaine Use and Infant Behavior

This study examined the impact of maternal cocaine use and associated risk factors such as polysubstance use, maternal functioning, and caregiving on affect regulation during infancy. Participants were 45 mother‐infant dyads (19 cocaine exposed and 26 control infants) recruited at birth. Observations and maternal reports of infant behavior were obtained at 2 and 7 months of age, along with measures of pre‐ and postnatal substance use, maternal functioning, and caregiving stability. Maternal cocaine use accounted for significant variance in infant positive affect at 2 months. Other substance use and gestational age predicted infant distress to novelty and arousal during developmental assessments. At 7 months, the impact of prenatal cocaine exposure on infant affect regulation was mediated by postnatal alcohol use and caregiving stability. These findings, if replicated, suggest that 1 pathway to later problem behavior reported among substance‐exposed children may be through early regulatory problems and the quality of postnatal caregiving.     

Young Infants' Behavioral Reactivity to Mild Perturbation: Developmental Continuity,Stability, and Organization

This study investigated the developmental continuity, stability, and organization of infants' behavioral response to mild stress from 1 to 3 months of age. Changes in infant stress reactivity were expected to coincide with a suspected neurobiological shift around the 2nd month. A total of 53 infants and their mothers participated in this study. At 1 and 3 months, infants' stress reactivity to mild perturbation was assessed by withdrawing a pacifier during nonnutritive sucking. Infant baseline heart rate activity and maternal reports of infant temperament were also obtained. Focusing on facial and vocal negativity, behavioral measures of infant reactivity to pacifier withdrawal were coded from videos. Results showed that developmental continuity and individual instability characterized changes in infant stress reactivity over the 2nd‐month transition. Developmental reorganization was also evidenced by changes in the direction and magnitude of infant stress reactivity in relation to baseline heart period and maternal temperament ratings, respectively. These findings provide direct supporting evidence for the contention that changes in infant stress reactivity to mild perturbation may be a function of developmental shifts in underlying neurobiological mechanisms in early infancy.     

Positive coparenting previous to the COVID-19 pandemic can buffer regulatory problems in infants facing the COVID-19 pandemic

Coparenting can be a development-enhancing or risk-promoting environment for infant regulatory capacity, mainly in the presence of adversity. This study aimed to analyze the association between positive and negative coparenting previous to the COVID-19 pandemic and infant regulatory capacity in the presence of the COVID-19 pandemic, an adverse condition. A sample of 71 first-born infants and their mothers and fathers from a longitudinal cohort in Portugal were assessed at 2 weeks postpartum before the COVID-19 pandemic and again at 6 months postpartum, before (n = 35) or during the COVID-19 pandemic (n = 36). Parents completed measures of positive and negative coparenting and infant regulatory capacity in both assessment waves. Results revealed that the presence of the COVID-19 pandemic moderates the association between mothers' and fathers' positive coparenting previous to the COVID-19 pandemic and infant regulatory capacity at 6 months. The association between positive coparenting and regulatory capacity was stronger in infants facing the COVID-19 pandemic, than in infants who did not face the COVID-19 pandemic. Positive coparenting previous to the COVID-19 pandemic may be a development-enhancing environment for infant regulatory capacity in the presence of the COVID-19 pandemic. Positive coparenting may buffer regulatory problems in infants facing adverse conditions.     

Mothers' Verbal and Nonverbal Strategies in Relation to Infants' Object‐Directed Actions in Real Time and Across the First Three Years in Ethnically Diverse Families

We examined maternal behavioral strategies in relation to infants' object‐directed actions in real time and over developmental time in 206 mother–infant dyads from African American, Dominican immigrant, and Mexican immigrant backgrounds. Mothers were asked to share a set of beads and strings with their infants when children were 14, 24, and 36 months. We coded three types of maternal strategies—eliciting attention, instructive assistance, and encouragement—which could be expressed verbally (e.g., “look”, “turn it”, “good job!”) or physically (i.e., through gestures, hands‐on guidance, or transfer of objects). We also coded infants' unassisted bead‐stringing. Across ethnic groups and ages, mothers' hands‐on guidance and object transfer increased the likelihood that infants would follow with unassisted bead‐stringing during real‐time interaction. Over developmental time, mothers modified their strategies: They displayed fewer attention‐getting strategies and more encouragement across infant ages, and peaked in their provision of instructive assistance when infants were 24 months. Additionally, Mexican mothers displayed more nonverbal strategies (e.g., gestures, hands‐on guidance) than did African American and/or Dominican mothers, who displayed more verbal strategies (e.g., attention‐getting and encouraging language). Developmental and real‐time patterns in mother–infant object‐related interactions generalize across ethnicities, although mothers' emphases on specific strategies are culture specific.     

Urgent engagement in 9/11 pregnant widows and their infants: Transmission of trauma

The potential effects of maternal trauma on mother–infant interaction remain insufficiently studied empirically. This study examined the effects of the September 11, 2001, trauma on mother–infant interaction in mothers who were pregnant and widowed on 9/11, and their infants aged 4–6 months. Split‐screen videotaped interaction was coded on a one‐second basis for infant gaze, facial affect, and vocal affect; and mother gaze, facial affect, and touch. We examined the temporal dynamics of communication: self‐contingency and interactive contingency of behavior by time‐series methods. We documented heightened maternal and infant efforts at engagement in the 9/11 (vs. control) dyads. Both partners had difficulty tolerating moments of looking away as well as moments of negative behavior patterns. Heightened efforts to maintain a positive visual engagement may be adaptive and a potential source of resilience, but these patterns may also carry risk: working too hard to make it work. A vigilant, hyper‐contingent, high‐arousal engagement was the central mode of the interpersonal transmission of the trauma to these infants, with implications for intervention.     

Microanalysis of 4-Month Infant Vocal Affect Qualities and Maternal Postpartum Depression

This study examined the association of 6-week maternal self-report depressive symptoms measured by the Center for Epidemiological Studies-Depression Scale (CES-D) with 4-month infant vocal affect qualities. This was part a larger study which examined many additional domains of both infant and maternal behavior. Infant vocal affect qualities were examined in 122 4-month old infants during face-to-face play in relation to 6-week maternal depressive symptoms. Mothers were categorized depressed (26.2%) based on a 16+ cutoff on the CES-D. Videotaped interactions were coded on a 1-s time basis for infant vocal affect qualities (high positive, neutral/positive, fuss/whimper, cry, angry protest and silent.) Infants of depressed mothers were more vocally activated in both positive and negative qualities. In addition, infants of depressed mothers were more vocally variable, specifically in and out of fuss/whimper, as well as more likely to change, rather than maintain vocal states.     

Parenthood and dynamics of life satisfaction in times of COVID-19

We analyze data from the UK Household Longitudinal Study, including a pre-pandemic baseline and seven survey waves between May 2020 and September 2021. Fixed effects panel regression models are run over more than 11,000 individuals, distinguishing among women and men with young children (<5 years), older children (5–15 years), or no children in the household. We hypothesize that declines in life satisfaction during the first lockdown are sharper among parents, whose domestic demands increase, than among the childless. We develop competing hypotheses that parents might be resilient and have higher life satisfaction during the later phases of the pandemic (Adaptation Hypothesis) or that the pandemic stressors accumulate, leading to even lower satisfaction over time (Accumulation Hypothesis). The results only support the Accumulation Hypothesis among mothers. Whereas mothers fared comparatively well during the first lockdown, further pandemic stressors have seemingly exhausted their resilience, leading to stronger declines during the winter 2020/2021 lockdown. Among men with older children and without children, life satisfaction decreased during the first and subsequent lockdowns. Men with young children were the only group with almost unchanged life satisfaction throughout the pandemic.     

Observed Infant Reactions During Live Interparental Conflict

Associations between interparental conflict and infant reactions were examined. Infants' history of exposure to interparental conflict and infant reactive temperament were examined as moderators. A community sample of 74 infants, aged 6–14 months, participated with their parents. Behavioral observations were made of parents' marital conflict and their infants' reactions. Parents reported on their emotional states during conflict, infants' history of exposure to interparental conflict, and infant temperament. Multilevel modeling indicated that infants showed differential responses to marital conflict; destructive and depressive conflict were associated with increased infant discussion attending and negative reactions, whereas constructive conflict was associated with decreased discussion attending and negative reactions. Infants' history of exposure to marital conflict and infant reactive temperament emerged as moderators.     

The Impact of Maternal Characteristics and Sensitivity on the Concordance Between Maternal Reports and Laboratory Observations of Infant Negative Emotionality

The moderating role of maternal characteristics and maternal sensitivity on the concordance between maternal reports and laboratory observations of negative emotionality was examined. Participants were 90 primiparous mothers and their infants. Mothers completed questionnaires about remembered care from their own parents and their depressive symptoms prenatally, infant temperament (distress to novelty and distress to limitations), and depressive symptoms postnatally. Mothers and infants participated in a laboratory assessment of infant temperament (distress to novelty and limitations) and maternal sensitivity at 6 months postpartum. Several factors that moderate the degree of concordance between maternal reports and behavioral observations were identified, as predicted. Novelty concordance was higher when mothers reported having their emotional needs met in childhood and low prenatal depressive symptoms. Limitations concordance was higher when mothers were less sensitive during the observational tasks. Methodological and theoretical implications are discussed.
