Mother-infant interaction and children's socio-emotional development with high- and low-risk mothers

Charting the dynamic character of mother-infant interaction requires using observational systems of sequential coding in real time. A longitudinal study was designed to approach maternal sensitivity in a more complex way using sequential analysis. The study was conducted with 20 high- and 20 low-risk mothers and their infants (aged: 3, 12 and 15 months) to examine the relation among mothers' risk status for physical abuse and their maternal interactive profiles, using micro-social sequential analyses, and the subsequent quality of attachment developed by their children at 15 months of age. Results showed significantly different timings in maternal responses in high- and low-risk groups, that the high-risk mothers were less sensitive: more intrusive and less discriminate regarding their infant's behavior. Significant differences between groups were also found after infant difficult behavior. High-risk mothers' infants were significantly more likely to develop insecure attachment. Sensitivity is proposed as a constellation of timings in early mother-infant interaction.     

The influence of maternal optimality and infant temperament on parenting stress at 12 months among mothers with substance abuse and psychiatric problems

The present prospective longitudinal study aimed to investigate the long‐term impact of maternal optimality assessed during pregnancy on parenting stress at infant age 12 months. In this study the concept of optimality was utilized to investigate maternal variations regarding resources during pregnancy in relation to later parenting stress, among three different groups of mothers that were recruited from substance abuse treatment, psychiatric outpatient treatment and well‐baby clinics respectively. The influence of infant temperament on parenting stress was also examined. All mothers were interviewed during pregnancy. At 12 months, infant temperament (Colorado Childhood Temperament Inventory; Rowe & Plomin, 1977) and stress in the parent and child domain (Parenting Stress Index; Abidin, 1955) were assessed. Results demonstrated higher levels of parenting stress among mothers in the clinical groups, compared to the non‐clinical group. Furthermore, it was the maternal psychiatric optimality index in combination with child temperament characteristics (child emotionality) that contributed uniquely to stress in the parent domain, while stress in the child domain was significantly associated only with child temperament characteristics (both child emotionality and soothability). The association between maternal psychiatric optimality assessed in pregnancy, infant temperament and parenting stress when the infants were 12 months old, points to the importance of simultaneously addressing the mothers' own psychological distress, and to support positive mother–infant interactions. Each woman's individual optimality profile may be used to display needs of follow‐up in order to prevent enduring effects of non‐optimality on parenting stress.     

“Hey mom, look at me!”

The degree to which infant and maternal characteristics were related to maternal psychological distress and play competence was examined in 40 mother preterm and full-term dyads. Measures of maternal psychological distress, self-efficacy, infant temperament, and mother-infant interaction in a play situation, were obtained at 4 months corrected for prematurity. Results revealed that maternal self-efficacy was the strongest correlate of maternal psychological distress but was not related to maternal play competence. Interaction effects for unadaptable temperament and infant behavioral involvement were found in the regressions predicting both maternal psychological distress and maternal play competence. Mothers of more adaptable and less behaviorally involved infants reported greater psychological distress and exhibited greater play competence than mothers of more adaptable and involved infants. The results suggest that a lack of concordance between mothers' perceptions of their infants' behavior and actual behavioral experiences adversely affects mothers' affect and the quality of their play interactions.     

Cortisol reactivity and negative affect among preterm infants at 12 months during a mother-infant interaction task

The purpose of this study was to investigate correlates of preterm (PT) infant’s cortisol reactivity and the association to infant negative affect, during a mother-infant interaction procedure. Participants included 48 infants born prematurely (gestational age < 37 weeks) and their mothers, assessed when infants were 12 months old corrected for prematurity. The examined variables comprised both neonatal and environmental dimensions including maternal interactive behavior. Infant negative affect and maternal interactive behavior were assessed with a standardized mother-infant interaction task. A baseline infant saliva sample was collected before the interaction began, and a second sample after the interaction episodes ended. Results revealed that decrease of infant’s cortisol concentration was significantly associated with the exposure to more sensitive, and less intrusive maternal behaviors. However, once controlled for neonatal risk, family SES and maternal psychological distress, the associations were rendered non-significant. Although the association between cortisol reactivity and negative affect trended toward significance, maternal intrusiveness was the only significant predictor of observed infant negative affect. Findings suggest the importance of primary relational experiences on PT infants' early regulatory competencies.     

Patterns of mother–infant interaction from 3 to 12 months among dyads with substance abuse and psychiatric problems

The aim of this study was to investigate the development of mother–infant interaction patterns from 3 to 12 months among three groups of mother–baby pairs recruited during pregnancy: one group from residential substance abuse treatment (n = 28), a second group from psychiatric outpatient treatment (n = 22), and a third group from well-baby clinics (n = 30). The mother–infant interaction at 3 and 12 months was assessed by the Parent–Child Early Relational Assessment (PCERA), which consists of maternal, child and dyadic subscales (Clark, 2006). Linear mixed effects models were used to analyze group differences and the changes in mother–infant interaction from 3 to 12 months.At 3 months, pairwise comparisons showed that the group with psychiatric problems had significantly more difficulties in the mother–infant interaction than the two other groups. The group with substance abuse problems was not significantly different from the two other groups. At 12 months, the mother–infant pairs in the substance abuse group showed significantly more relational disturbances than the non-clinical pairs, as well as a poorer affective quality of interaction than the dyads in the group with psychiatric problems. Analysis of change from 3 to 12 months showed that difficulties in the interaction increased among the mother–baby pairs in the substance abuse group, while improvements were displayed in the two other groups. These results underline that mother–infant pairs at double risk due to maternal substance abuse and other non-optimal factors, are in need for long-term follow up in order to prevent the development of negative interactional patterns.     

MATERNAL TRAUMA AFFECTS PRENATAL MENTAL HEALTH AND INFANT STRESS REGULATION AMONG PALESTINIAN DYADS

We examined how diverse and cumulated traumatic experiences predicted maternal prenatal mental health and infant stress regulation in war conditions and whether maternal mental health mediated the association between trauma and infant stress regulation. Participants were 511 Palestinian mothers from the Gaza Strip who reported exposure to current war trauma (WT), past childhood emotional (CEA) and physical abuse, socioeconomic status (SES), prenatal mental health problems (posttraumatic stress disorder and depression symptoms), and perceived stress during their secondtrimester of pregnancy as well as infant stress regulation at 4 months. While all trauma types were associated with high levels of prenatal symptoms, CEA had the most wide‐ranging effects and was uniquely associated with depression symptoms. Concerning infant stress regulation, mothers’ CEA predicted negative affectivity, but only among mothers with low WT. Against hypothesis, the effects of maternal trauma on infant stress regulation were not mediated by mental health symptoms. Mothers’ higher SES was associated with better infant stress regulation whereas infant prematurity and male sex predisposed for difficulties. Our findings suggest that maternal childhood abuse, especially CEA, should be a central treatment target among war‐exposed families. Cumulated psychosocial stressors might increase the risk for transgenerational problems.     

Mother–infant interaction and maternal postnatal psychological distress are associated with negative emotional reactivity among infants and toddlers— A FinnBrain Birth Cohort study

Studies have reported mixed findings regarding the effects of mother-infant interaction and maternal distress on children’s negative emotional reactivity. In the current study (N = 134 and 107), we examined the effects of maternal Emotional Availability (sensitivity, structuring, non-intrusiveness and non-hostility) and maternal psychological distress on negative reactivity among children in the FinnBrain birth cohort study. In addition, the possible moderating effect of mother-infant interaction on the associations between maternal psychological distress and children's negative reactivity was examined. We used questionnaires to asses maternal psychological distress, observations of mother-infant interaction and observations as well maternal reports of child temperament to overcome the key limitations of many studies relying on single-method assessments. Our results showed that higher maternal sensitivity and structuring at 8 months of child’s age were associated with lower mother-reported negative reactivity among children at 24 months. Higher maternal postnatal distress associated with higher parent-reported negative reactivity in children at 12 and 24 months of age when the effects of prenatal distress and the quality of mother-infant interaction were controlled for. Mother-infant interaction and maternal psychological distress did not associate with observations of child negative reactivity. We found no moderation effects of mother-infant interaction regarding the associations between maternal distress and children’s negative emotional reactivity. Our findings reflect the importance of developing interventions to reduce the maternal distress symptoms while enhancing maternal sensitivity and structuring to prevent the possible harmful effects of these on child negative reactivity.     

Interactions between mothers and infants: impact of maternal anxiety

The aim of the study was to examine the impact of anxiety in the postnatal year on maternal contribution to mother-infant interaction. Participants were 32 mothers with high anxiety and 32 mothers with low anxiety, when their infants were aged 10-14 months. Mother-infant interaction was videotaped during a standardized play situation and coded blind to group status. High trait anxiety mothers showed less sensitive responsivity (p<.05) and reduced emotional tone (p<.05) during interaction. When participants scoring high in depressive symptomatology were removed for a subgroup analysis, the same pattern of results was obtained, suggesting that the observed differences in mother-infant interaction were due to group differences in anxiety.     

Maternal attitudes during pregnancy predict mother-infant physical proximity six months after birth

The purpose of this study was to develop an instrument for assessing maternal attitudes. Three photographs representing infants or mother-infant dyads were presented to 26 mothers in the second half of pregnancy and six months after birth. Nine mothers were clinical cases, seventeen mothers were nonpathological controls. Thirty-three semantic categories were used to code the mothers' responses to the pictures. Mothers' responses were coded independently by two researchers. The factor analysis of the codes yielded an ‘attraction to, vs rejection of, children’ factor. Compared with the control group, the mean factor score of the clinical group was significantly lower, i. e. reflected less attraction (p < 0.01). To study the relation between the attraction factor and the physical proximity of mothers and infants, 21 of these mother-infant dyads were videotaped in a semi-structured play interaction six months after birth. Recordings were coded independently by two researchers for various indices of proximity (spatial proximity, kisses, embraces, touches). The factor analysis of the codes yielded a factor contrasting distant vs close and tender interaction. A significant correlation was found between the attraction scores of pregnant women and the proximity scores of mother-infant interaction (r = 0.46; p < 0.05). These results suggest that this instrument is useful in assessing maternal attitudes of psychiatrically disturbed pregnant women and that maternal attitudes of pregnant women are significant predictors of physical proximity in motherinfant interaction at the end of the first semester.     

祖辈共同看护背景下母亲和祖辈将心比心、母子依恋与婴幼儿认知的关系:一个有调节的中介模型

Mothers with depressive symptoms: cross-situational consistency and temporal stability of their parenting behavior

In the present study, it has been hypothesized that anxious and depressed mothers may show less typical behavior in a laboratory observational setting because they may be more affected by unfamiliarity and the social evaluative meaning of the situation. They may thus show low consistency across laboratory and home assessments. A sample of 101 mother-infant pairs participated in the longitudinal study. Laboratory and home observations of mother-infant interaction episodes were conducted at the infant ages of 4, 8, and 12 months. Consistent with expectations, at 4 months the association between laboratory- and home-assessed maternal sensitivity was significantly moderated by maternal depression/anxiety: in highly anxious/depressed mothers the association between laboratory- and home-assessed sensitivity was weak, whereas a strong association was found in mothers with low anxiety/depression. At 8 months this interaction was still marginally significant and at 12 months it had disappeared. Thus, mothers with depressive symptoms showed less consistent behavior across the two settings of the first assessment wave, and with increased familiarity with the procedures of the longitudinal study, their behavioral consistency increased and no longer differed from that of well mothers.     

The effects of polydrug use with and without cocaine on mother-infant interaction at 3 and 6 months

The face-to-face interactions of 43 polydrug-with-cocaine-using mothers and their infants at 3 and 6 months were compared to 17 non-cocaine-but other-drug-using mothers and 21 mothers who used no drugs during their pregnancy. Coders blind to mothers' drug use status scored 3 min of face-to-face interactions for 16 measures of maternal and infant interactive behaviors. A principal component of 7 behaviors formed a measure of maternal attentiveness; a principal component of 5 behaviors formed a measure of mother-infant dyadic organization; and a principal component of 4 behaviors formed a measure of infant readiness to interact. A measure of maternal interruption was computed as the mean standard score of 3 additional interruptive behaviors. At 3 and 6 months, polydrug-with-cocaine-using mothers were less attentive to interactions, and polydrug-with-cocaine-using mothers and their infants engaged in fewer dyadic interactions than either non-cocaine or non-drug-using mothers. Compared to 3 months, polydrug-with-cocaine-using mothers at 6 months were less attentive to interactions and more frequently interrupted interactions by looking away, redirecting the infant, or withdrawing, whereas non-cocaine-using and non-drug- using mothers showed no change or an improvement in attentiveness to interactions and a decrease in interruptions. No differences emerged in the interactive behaviors of the infants of polydrug- with-cocaine-using, non-cocaine-using, or non-drug-using mothers. Cocaine use represents a significant risk for diminished parental attentiveness and responsiveness to infants and for diminished interactiveness in infants.     

Consistency in maternal affect and positive vocalization over the first year of life

Consistency in parenting infants has positive developmental outcomes. Yet, the role of socioeconomic status (SES) in consistency of maternal behaviors is not well understood. We investigated individual-order continuity of maternal smile and laughter and positive vocalization from 6 to 12 months of age in 82 mother-infant dyads. Overall, individual differences in maternal smile and laughter, and positive vocalization were consistent across time. A multidimensional measure of SES moderated the association of maternal smile and laughter from 6 to 12 months, such that infants from lower SES families were vulnerable to unpredictable parenting - experiencing a lack of consistency in maternal smiles and laughter.     

Language experiences and vocabulary development in Dominican and Mexican infants across the first 2 years

We longitudinally investigated parental language context and infants' language experiences in relation to Dominican American and Mexican American infants' vocabularies. Mothers provided information on parental language context, comprising measures of parents' language background (i.e., childhood language) and current language use during interviews at infants' birth. Infants' language experiences were measured at ages 14 months and 2 years through mothers' reports of mothers' and fathers' engagement in English and Spanish literacy activities with infants and mothers' English and Spanish utterances during videotaped mother-infant interactions. Infants' vocabulary development at 14 months and 2 years was examined using standardized vocabulary checklists in English and Spanish. Both parental language context and infants' language experiences predicted infants' vocabularies in each language at both ages. Furthermore, language experiences mediated associations between parental language context and infants' vocabularies. However, the specific mediation mechanisms varied by language.     

Longitudinal associations between the quality of parent-child interactions and children's sleep at preschool age

This study aimed to examine the prospective longitudinal links between the quality of mother-child and father-child interactions and preschoolers' sleep. Three dimensions of maternal interactive behavior were considered using 70 mother-child dyads, while the quality of father-child interactions was assessed using 41 of these families. Maternal mind-mindedness was assessed at 12 months during a mother-infant free-play sequence, maternal sensitivity was rated at 12 months based on observations performed throughout a home visit, maternal autonomy support was assessed at 15 months with a 10-min problem-solving situation, and the quality of father-child interactions was scored at 18 months, during father-child free play. Children's sleep was assessed at 3 and 4 years using a sleep diary completed by mothers during 3 consecutive days. Results indicated that, after controlling for family socioeconomic status and daycare attendance, the quality of both mother-infant and father-infant interactions was positively related to children's percentage of night-time sleep at preschool age. These findings add to previous literature in suggesting that early caregiving behavior by both mothers and fathers is related to subsequent child sleep.     

Preterm birth and maternal sensitivity: Findings from a non-western country

IntroductionAlthough there are several studies on maternal sensitivity of preterm-born children conducted in Western countries, the factors affecting the sensitivity of mothers of preterm infants have not been investigated outside the Western context.ObjectivesThis study aimed to compare maternal sensitivity of preterm children at 18 months of corrected age with their healthy term-born peers and explore the factors associated with maternal sensitivity in a middle-income non-Western country. Moreover, the associations of maternal sensitivity with socio-demographic factors, maternal depression, and social-emotional competency and behavior problems of infants were investigated.MethodsIn total, 70 (40 preterm-born and 30 term-born) mother-child dyads participated in this study. An observation-based measurement tool, Maternal Sensitivity Scale, was used to assess maternal sensitivity. Social-emotional competency and behavior problems of infants were evaluated via The Turkish version of the Brief Infant-Toddler Social Emotional Assessment. Maternal depressive symptoms were assessed via the Beck Depression Inventory. In addition, a demographic information form was filled out by the mothers.ResultsMaternal sensitivity scores of preterm infants were significantly lower compared to term infants. Depressive symptoms scores and employment status of mothers, socio-economic status (SES), gestational age, breastfeeding duration, and behavior problems of children were the factors related to maternal sensitivity scores. In hierarchical regression analysis, SES and gestational age were the strongest predictors of maternal sensitivity. After controlling SES and gestational age, maternal depressive symptoms scores negatively predicted maternal sensitivity scores.ConclusionThis study pointed out the factors associated with the maternal sensitivity of preterm infants outside the Western context. Interventions to improve sensitive parenting behaviors of preterm infants are needed, especially in socio-economically disadvantaged groups.     

The effects of maternal mood on mother-infant interaction

The effects of depressed mood on mother-infant interaction were studied in 30 mother-infant dyads using the Velten mood induction procedure. It was predicted that maternal depressed mood would induce dysphoria in the infants, disrupt the infants' natural responsiveness to their mothers, and interfere with the mothers' ability to manage the interaction. In addition, it was predicted that such deficits would be the result of depressed maternal mood and not simply due to any change in maternal mood. The results indicated that the infants were sensitive to depressed mood and were less contingently responsive to their mothers than were controls. Also, mothers in the depression induction condition were less successful in eliciting positive responses from their infants than were controls. These results have implications for the development of a helplessness vulnerability in infants and for the two-way direction of effect present in depressed mother-infant dyads.This research was partially funded by NIMH grant MH39283 and a Spelman-Rockefeller Seed Grant awarded to Michael O'Hara.

The role of oxytocin in early mother-infant interactions: Variations in maternal affect attunement

The aim of the present research was to investigate the relationship between oxytocin and maternal affect attunement, as well as the role of affect attunement in the relationship between oxytocin and infant social engagement during early mother-infant interactions. Forty-three mother-infant dyads participated in the present study when infants were 4 months. They were observed during (1) a situation where no communication took place and (2) a natural interaction between mother and infant. During this procedure, three saliva samples from mothers and their infants were collected to determine their levels of oxytocin at different time points. Maternal affect attunement (maintaining attention, warm sensitivity) and infant interactive behaviors (gaze, positive, and negative affect) were coded during the natural interaction. Results indicated that overall maternal oxytocin functioning was negatively related to her warm sensitivity, while infant oxytocin reactivity together with maternal affect attunement were associated with infant positive social engagement with their mothers. Specifically, infant oxytocin reactivity was significantly related to their gazes at mother, but only for infants of highly attuned mothers. These results point to the complex role oxytocin plays in parent-infant interactions while emphasizing the need to analyze both overall oxytocin functioning as well as reactivity as different indices of human affiliative behavior.     

Crises in parents of prematures: An Australian study

The behaviour of 24 mothers of infants with birth weights below 1500 grams was examined relative to the four psychological ‘tasks’ which, according to Caplan et al. (1965), accompany pre-term birth. Data gathered between birth and discharge of the infants and at ‘follow-up’ visits permitted an investigation of the intensity of maternal experience of these tasks, of mothers' success in grappling with them and of the relationship between success in grappling and later mother-infant relationships. Certain personal, sociological and infant variables associated with maternal behaviour were identified. Ability to cope with the crises was related to better mother-infant relationships at one month and markedly superior ones at four months. The necessity for assisting mothers to cope with the immediate and later psychological disequilibrium is emphasized.     

Perceptions of maternal and paternal solicitude by birth children and adoptees: Relevance for maternal bonding theory

This study emanated from the long-standing question of whether a maternal bonding process similar to other mammalian species occurs in humans. The perceptions of adult adoptees and a matched sample of non-adoptees about their parents' behaviours towards them were compared on an original Parental Solicitude Scale. As hypothesized, birth children perceived their mothers as the more solicitous parent, but ratings of adoptive mothers showed a unilateral decline. Further, the differential ratings for birth and adoptive mothers occurred mostly for the factors labelled benignity vs abuse and tolerance vs control, rather than caretaking vs neglect, which was congruent to reported effects in prior studies of lack of mother-infant contact during the sensitive period for bonding. An alternative explanation of the data was also tested but not substantiated.
