Depressed mothers’ infants show less negative affect during non-contingent interactions

Infants of depressed and non-depressed mothers were videotaped interacting with their mothers in the [Nadel, J., Carchon, I., Kervella, C., Marcelli, D., & Reserbat-Plantey, D. (1999). Report: Expectancies for social contingency in 2-month-olds. Developmental Science, 2, 164–173] paradigm which consists of three segments including: (1) a free play, contingent interaction, (2) a non-contingent replay of the mothers’ behavior that had been videotaped during the first segment, and (3) a return to a free play, contingent interaction. As compared to infants of non-depressed mothers, infants of depressed mothers showed less negative change (less increase in frowning) in their behavior during the non-contingent replay segment. This finding was interpreted as the infants of depressed mothers being more accustomed to non-contingent behavior in their mothers, thus experiencing less violation of expectancy in this situation.     

Two-month-old infants of depressed mothers show mild, delayed and persistent change in emotional state after non-contingent interaction

The aim of this study was to explore how early infants show different responses to non-contingent maternal behavior according to their past history of relations with their mother. Two groups of 2-month-olds interacted with their mother who was assessed as depressed (group 1) or non-depressed (group 2). Although they received a continuous image and voice of their mothers, the infants were presented either a 30-s contingent maternal communication (live episode 1) or a thirty second non-contingent episode (replay of prior maternal communication), or again a 30-s contingent live episode (live2). The lower percentage of negative facial expressions displayed during replay by infants of depressed mothers suggests on one hand that they are less sensitive to a non-contingent maternal behavior than infants of non-depressed mothers. However, within group comparisons demonstrate a notable difference: while infants of non-depressed mothers show a U curve of smile, infants of depressed mothers show decreasing smile throughout the three episodes. Taken together, these results plead in favour of an other profile of sensitivity displayed by infants of depressed mothers. Instead of the strong but short-term reaction of infants of non-depressed mothers, the response of infants of depressed mothers appeared to be a mild, delayed and more persistent change in emotional state. These findings are discussed in the light of possible cognitive and social incidence of passive avoidance of stressful events in infants of depressed mothers.     

Individual differences in non-clinical maternal depression impact infant affect and behavior during the still-face paradigm across the first year

Maternal depression can significantly impact mothers’ sensitivity to their infants’ needs as well as infants’ social and emotional development. The still-face paradigm (SFP) is widely used to assess infants’ understanding of the contingency between their own behavior and that of their caregivers, as well as infants’ ability to self-regulate arousal levels during sudden changes in maternal responsiveness. Infants of clinically depressed mothers display blunted levels of negative affect compared to infants of non-depressed mothers during the still-face (SF) phase. However, little is known about whether individual differences in elevated, non-clinical levels of maternal depression similarly affect mother-infant interactions. The current study examines the longitudinal effects of non-clinical maternal depression on infant and maternal behaviors during the SFP. Infants (N = 63) were assessed at 5 and 9 months and maternal depression was assessed at 5 months using the Beck Depression Inventory (BDI). Infants of mothers with elevated levels of depression displayed less negative engagement during the SF phase compared to infants of mothers with lower levels of depression. This effect was present at 5 months, but not at 9 months. Findings demonstrate that non-clinical levels of maternal depressive symptomatology can have a significant impact on infants’ affective regulation during the first half of the first year of life, but this does not necessarily have a long-lasting influence later in infancy. Interventions may want to target mothers with non-clinical depression to promote healthy infant social and emotional development.     

Facial expressions and vagal tone of infants of depressed and non-depressed mothers

Mothers classified as ‘depressed’, ‘non-depressed’ or ‘low scoring’ on the Beck Depression Inventory and their 3-month-old infants were videotaped during 3-minute face-to-face play interactions. Infants' facial expressions were coded using the AFFEX facial expression coding system and their EKG was recorded during the interactions to assess the relationship between cardiac measures and facial expressivity. Infants of both ‘depressed’ and ‘low scoring’ mothers showed significantly more sad and anger expressions and fewer interest expressions than infants of nondepressed mothers. Cardiac vagal tone, (quantified from the amplitude of respiratory sinus arrhythmia) was correlated with infants' joy and interest expressions and with self-comfort behaviours in the non-depressed and low scoring groups, but not in the depressed group. The results suggest that matermal depression affects infants' affective state and appearance as well as their biobehavioural emotional regulation systems.     

Precursors of social emotional functioning among full-term and preterm infants at 12 months: Early infant withdrawal behavior and symptoms of maternal depression

This study forms part of a longitudinal investigation of early infant social withdrawal, maternal symptoms of depression and later child social emotional functioning. The sample consisted of a group of full-term infants (N = 238) and their mothers, and a group of moderately premature infants (N = 64) and their mothers. At 3 months, the infants were observed with the Alarm Distress Baby Scale (ADBB) and the mothers completed the Edinburgh Postnatal Depression Scale (EPDS). At 12 months, the mothers filled out questionnaires about the infants’ social emotional functioning (Infant Toddler Social Emotional Assessment and the Ages and Stages Questionnaire-Social Emotional). At 3 months, as we have previously shown, the premature infants had exhibited more withdrawal behavior and their mothers reported elevated maternal depressive symptoms as compared with the full-born group. At 12 months the mothers of the premature infants reported more child internalizing behavior. These data suggest that infant withdrawal behavior as well as maternal depressive mood may serve as sensitive indices of early risk status. Further, the results suggest that early maternal depressive symptoms are a salient predictor of later child social emotional functioning. However, neither early infant withdrawal behavior, nor gestational age, did significantly predict social emotional outcome at 12 months. It should be noted that the differences in strength of the relations between ADBB and EPDS, respectively, to the outcome at 12 months was modest. An implication of the study is that clinicians should be aware of the complex interplay between early infant withdrawal and signs of maternal postpartum depression in planning ports of entry for early intervention.     

Maternal postpartum depression is a risk factor for infant emotional variability at 4 months

Maternal postpartum depression (PPD) is a risk for disruption of mother–infant interaction. Infants of depressed mothers have been found to display less positive, more negative, and neutral affect. Other studies have found that infants of mothers with PPD inhibit both positive and negative affect. In a sample of 28 infants of mothers with PPD and 52 infants of nonclinical mothers, we examined the role of PPD diagnosis and symptoms for infants’ emotional variability, measured as facial expressions, vocal protest, and gaze using microanalysis, during a mother–infant face-to-face interaction. PPD symptoms and diagnosis were associated with (a) infants displaying fewer high negative, but more neutral/interest facial affect events, and (b) fewer gaze off events.  PPD diagnosis, but not symptoms, was associated with less infant vocal protest. Total duration of seconds of infant facial affective displays and gaze off was not related to PPD diagnosis or symptoms, suggesting that when infants of depressed mothers display high negative facial affect or gaze off, these expressions are more sustained, indicating lower infant ability to calm down and re-engage, interpreted as a disturbance in self-regulation. The findings highlight the importance of not only examining durations, but also frequencies, as the latter may inform infant emotional variability.     

Correlation between maternal and infant cortisol varies by breastfeeding status

ObjectiveThe objective of this study was to examine associations of mother and infant salivary cortisol, measured three times over the course of a day, and assess whether these varied by breastfeeding status.MethodsWe conducted a cross-sectional study of 54 mothers and their infants aged 4–11 months. Mothers collected their own saliva and that of their infants upon awakening, 30 min after waking and at bedtime. Breastfeeding status was reported by mothers and cortisol level was measured in saliva in μg/dl using standard techniques. We used generalized linear models to evaluate relationships between maternal and infant cortisol levels, and assessed whether the relationship differed by breastfeeding status: formula only compared to partial and full breastfeeding, adjusting for infant sex, race, age, maternal education, and family income.ResultsThirty-four infants received formula only and 20 were either partially or fully breastfed. Breastfeeding was associated with higher household income, higher maternal education, and white race. Cortisol levels were higher among breastfed infants at all three time points. After adjustment, maternal cortisol levels were related with infant cortisol at bedtime only (regression estimate 0.06; 95% CI: 0.10, 1.1; p = 0.02). The adjusted association between bedtime maternal and infant cortisol was stronger among breastfeeding dyads than among formula-feeding dyads (regression estimate 1.0; 95% CI: 0.1, 2.0; p = 0.04 vs. 0.6; CI: −0.1, 1.3; p = 0.10). In addition, we assessed the influence of maternal education and household income in our adjusted model; income strengthened the observed association, whereas maternal education did not change the estimate.ConclusionsBreastfeeding mothers and infants had significant correlations for cortisol at bedtime, while formula-feeding dyads did not. These data suggest that several factors may contribute to cortisol synchrony observed in mother/infant dyads, including the transfer of cortisol in human milk, physical interaction such as skin-to-skin contact, and shared environment. In addition, our findings support household income as a possible contributor.     

Alcohol use and dating violence among college students

IntroductionNumerous studies have focused on the association of dating violence (DV) and alcohol use. However, little research has as yet assessed their co-occurrence in short timeframes.ObjectiveThis study aims to investigate alcohol use in the two hours preceding DV and in the two hours following DV.MethodCollege students (n = 649, 71% females, mean age = 19.8) reported their experience of DV and their hazardous drinking on self-administered questionnaires. They also reported their alcohol use in the two hours preceding – as well as following – a specific DV event (i.e. insult between dating partners).ResultsChi-square tests outline that alcohol use in the two hours preceding an insult is associated with alcohol use in the two hours following an insult. Regressions show that higher scores of hazardous drinking puts students at risk of insulting or being insulted in a context of alcohol use.ConclusionThe findings can contribute to DV prevention programs among college students.     

Unattractive infant faces elicit negative affect from adults

We examined the relationship between infant attractiveness and adult affect by investigating whether differing levels of infant facial attractiveness elicit facial muscle movement correlated with positive and negative affect from adults (N = 87) using electromyography. Unattractive infant faces evoked significantly more corrugator supercilii and levator labii superioris movement (physiological correlates of negative affect) than attractive infant faces. These results suggest that unattractive infants may be at risk for negative affective responses from adults, though the relationship between those responses and caregiving behavior remains elusive.     

Development of mother–infant interaction in tickling play: The relationship between infants’ ticklishness and social behaviors

This study examined the development of mother–infant tickling interaction and the relationship between infants’ ticklishness and social behaviors including infants’ looking at mothers’ face, mothers’ narrative tickling, and mothers’ laughter. Twenty-two Japanese infants aged 5 months (n = 10, five girls) and 7 months (n = 12, four girls) and their mothers were videotaped. Results revealed that the mothers’ narrative tickling was more frequent at 7 than at 5 months and the infants’ strong ticklishness showed the same tendency. The infants’ strong ticklishness was linked with the occurrence of other social behaviors. In conclusion, infants’ ticklishness was heavily connected with social behaviors. The mode of the tickling interaction at 7 months was different from that at 5 months especially in the increase of mother’s narrative tickling. A possible function of such mother’s narrative tickling to facilitate infant active communication at a higher cognitive level including anticipation, was discussed.     

Depressed mothers' and their infants' interactions with nondepressed partners

Twenty depressed adolescent mothers were videotaped interacting with their own infant and with the infant of a nondepressed mother. In addition, nondepressed mothers were videotaped with their own infant as well as with the infant of a depressed mother. Depressed mothers showed less facial expressivity than nondepressed mothers and received less optimal interaction rating scale scores (a summary score for state, physical activity, head orientation, gaze, silence during gaze aversion, facial expressions, vocalizations, infantized behavior, contingent responsivity, and gameplaying). This occurred independent of whether they were interacting with their own infant versus an infant of a nondepressed mother, suggesting that depressed mothers display less optimal behaviors to infants in general. The infants of both depressed and nondepressed mothers received better head orientation and summary ratings when they were interacting with another mother, perhaps because the other mother was more novel. Infants of nondepressed mothers, in particular, had better summary ratings (state, physical activity, head orientation, gaze, facial expressions, fussiness, and vocalizations) than the infants of depressed mothers when interacting with depressed mothers. Thus, it may be that infants of nondepressed mothers are generally better interaction partners than infants of depressed mothers. Another related possibility is that they persist longer in trying to elicit a response from mothers less responsive than their own, given that they have learned to expect a response to their behavior.     

Mothers' Perceptions of Infants Labelled ‘Depressed’

Forty-four depressed and non-depressed mothers participated in a videotaped interaction with their own infant and then rated the videotape using the Infant Stereotyping Scale and the Interaction Rating Scale. In addition, one half of the mothers rated a videotape of an unfamiliar infant who was labelled psychologically ‘depressed’ and the other half rated a videotape of the same infant with no label given. Both the depressed and non-depressed mothers rated the ‘depressed’ labelled infant more negatively than the non-labelled infant on the attributes of physical potency, cognitive competence, sociability and difficult behaviour. Physical appearance was the only rating that was not biased by the ‘depressed’ label. Mothers' ratings of their own infants were more positive than their ratings of the non-labelled stimulus infant. Depressed mothers did not see their infants more negatively except on one rating. They rated the physical appearance of their own infant more negatively than non-depressed mothers.     

Attention-getting vs. imitation effects on depressed mother-infant interactions

The effects of instructing mothers to “imitate” their infant versus “keep their infant's atten tion” were examined during mother-infant face-to-face interactions of 18 mothers reporting depressive symptoms as compared with 22 mothers who did not report such symptoms. Mothers were generally rated as showing more positive facial expressions and more game playing (particularly the depressed mothers) during the attention-getting versus the imitation sessions. The infants received more optimal physical ac tivity, and facial expression ratings during attention getting, and the infants of depressed mothers, in par ticular, showed more positive facial expressivity and more joy expressions. As might be expected for the imitation condition, mothers showed more imitative behavior, contingent responsivity, and silence during gaze aversion. Infants generally showed more disinterest and self-comfort behaviors, and the infants of depressed mothers, in particular, showed more anger expressions, fussiness, and squirming during the imitation condition. The data suggest that the attention-getting condition was the most effective “intervention” for eliciting positive behavior in the depressed mother-infant dyads.     

Perinatal depression influences on infant negative affectivity: Timing,severity, and co-morbid anxiety

Accumulating evidence suggests that antenatal depression predicts infants’ negative affectivity, albeit with variable effect sizes. With a prospective longitudinal design, we sought to explain that variability by addressing questions about timing of the depression across pregnancy and the early postpartum, the role of high symptom levels relative to diagnosed depression, comorbidity with anxiety, and the potential mediating role of neuroendocrine functioning. Primiparous women (n = 77) with histories of depression prior to pregnancy were assessed for cortisol levels monthly beginning by mid-pregnancy. Depression symptom levels and diagnostic status were similarly assessed monthly in pregnancy and also until infants reached three months of age, when mothers completed the Infant Behavior Questionnaire-Revised to measure infant negative affectivity. Antenatal depression symptoms and infant negative affectivity were positively associated (r = .39). Controlling for depression symptom levels in other trimesters, only second trimester depression symptoms predicted higher infant negative affectivity (β = .44). With postpartum depression symptom levels in the model, only antenatal depression symptoms predicted infant negative affectivity (β = .45). In the context of depression, neither antenatal anxiety symptoms nor anxiety disorder diagnosis were associated with infant NA scores. The hypothesized role of elevated maternal cortisol as a mechanism for the association between antenatal depression and infant NA was not supported. Our findings contribute to efforts to more precisely identify infants of perinatally depressed mothers who are at greater risk for elevated negative affectivity, suggesting a window of vulnerability in mid pregnancy and the need for further study of potential mechanisms.     

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.     

Mother and infant affective involvement states and maternal depression

This study shows two different dimensional types of maternal depression, one dull and slow, the other stressed and irritable. When the quality of the infant attachment to mother is assessed, it is noted that the dimensional aspect of the maternal depression can be of some importance in the quality of the attachment. In fact, children are more inclined to develop an insecure–ambivalent attachment to their stressed depressed mothers, while children of slow depressed mothers are more insecure–avoiding. Thus, the dimensions of maternal depression can be an indicator of the type of insecure attachment of the infant at one year of age. We have also found that insecure children of depressed mothers express very little joy in the course of face-to-face interactions. A parallel can be established between the characteristics of the different affective dimensions of the maternal depression, the affective involvement state level of the partners, their synchrony or non-synchrony, the affective expression of the baby, and the type of insecure attachment to the mother. Thus, affective interaction may be an indicator of the child's development, both to assess the interaction and to evaluate the type of attachment shown by the child, indicating that previous interactive patterns have been internalized. © 1997 Michigan Association for Infant Mental Health     

The role of BIS/BAS in the vulnerability for depression in adolescent girls

Reinforcement Sensitivity Theory (RST), the original (i.e. Gray, 1982) or revised (Gray & McNaughton, 2000), has yet to be used as a framework for investigating vulnerability to Major Depressive Disorder (MDD) in adolescents. The present study employed a high-risk design to examine whether aberrant BIS-FFFS/BAS activity was similarly present in both depressed girls and girls at high risk for depression.MethodsN = 85 age-matched biological daughters of mothers with differential MDD status: (a) MDD (n = 17), (b) high-risk (n = 34), and (c) healthy controls (n = 34) completed measures of the BIS/BAS, depression, and anxiety.ResultsMDD girls scored significantly higher on BIS than healthy controls but not high-risk girls, and the high-risk and control groups did not differ. No group differences were found on BAS or FFFS-Fear.ConclusionsElevated BIS was not identified as a vulnerability factor for MDD; however, it does distinguish depressed adolescents from healthy controls.     

Longitudinal effects of contextual and proximal factors on mother-infant interactions among Brazilian adolescent mothers

Adolescent mothers often come from vulnerable backgrounds which might impact the quality of both maternal and infant behavior. Despite the negative impact of adolescent motherhood for maternal and infant behavior, social support may decrease the risks and promote maternal behavior toward the infant. The aim of this study was to investigate longitudinally the effects of proximal (maternal behavior) and distal (mother’s perceived social support) variables on infant development in a sample of Brazilian adolescent mothers and their infants. Thirty-nine adolescent mothers (M_age = 17.26 years; SD = 1.71) were observed interacting with their infants at 3 and 6 months postpartum and reported on social support. Results revealed that maternal and infant behavior were associated within and across times. Mothers’ perceived social support at 3 months had an indirect effect on infant behavior at 6 months, totally mediated by maternal behavior at 6 months. Our findings revealed the mutual influence between maternal and infant behavior, revealing a proximal process. The results also underscored the importance of the passage of time in the interplay between mother-infant interactions and their developmental context.     

Through babies’ eyes: Practical and theoretical considerations of using wearable technology to measure parent–infant behaviour from the mothers’ and infants’ view points

AimsTo explore the utility of first-person viewpoint cameras at home, for recording mother and infant behaviour, and for reducing problems associated with participant reactivity, which represent a fundamental bias in observational research.MethodsWe compared footage recording the same play interactions from a traditional third-person point of view (3rd PC) and using cameras worn on headbands (first-person cameras [1st PCs]) to record first-person points of view of mother and infant simultaneously. In addition, we left the dyads alone with the 1st PCs for a number of days to record natural mother–child behaviour at home. Fifteen mothers with infants (3–12 months of age) provided a total of 14 h of footage at home alone with the 1st PCs.ResultsCodings of maternal behaviour from footage of the same scenario captured from 1st PCs and 3rd PCs showed high concordance (kappa >0.8). Footage captured by the 1st PCs also showed strong inter-rater reliability (kappa = 0.9). Data from 1st PCs during sessions recorded alone at home captured more ‘negative’ maternal behaviours per min than observations using 1st PCs whilst a researcher was present (mean difference = 0.90 (95% CI 0.5–1.2, p < 0.001 representing 1.5 SDs).Conclusion1st PCs offer a number of practical advantages and can reliably record maternal and infant behaviour. This approach can also record a higher frequency of less socially desirable maternal behaviours. It is unclear whether this difference is due to lack of need of the presence of researcher or the increased duration of recordings. This finding is potentially important for research questions aiming to capture more ecologically valid behaviours and reduce demand characteristics.     

Infant sleep-wake behaviors at two weeks,three and six months

Although infant sleep-wake behavior presents several developmental changes during the first six months, literature lacks on reference values and few studies have explored the role of individual change and stability on infant sleep-wake behavior during the first six months. This study aimed (1) to describe infant sleep-wake behaviors during the 24-h period, day and night, at two weeks, three, and six months, (2) and to explore developmental changes and the role of individual change and stability on infant sleep-wake behaviors from two weeks to six months. Ninety-four primiparous mothers completed measures on infant sleep-wake behaviors at two weeks, three and six months. Significant developmental changes were found on infant sleep-wake behaviors from two weeks to six months. Two-week-old infants sleep 13.3 h, spend 8.7 h awake, awake 6.1 times, have 0.4 h of latency to sleep, and 3.2 h of longest sleep period. Three-month-old infants sleep 13.0 h, spend 9.2 h awake, awake 5.5 times, have 0.4 h of latency to sleep, and 5.2 h of longest sleep period. Six-month-old infants sleep 12.2 h, spend 10.0 h awake, awake 5.2 times, have 0.4 h of latency to sleep, and 5.6 h of longest sleep period. Significant individual change and stability were also found on infant sleep-wake behaviors from two weeks to six months. Despite significant developmental and individual changes, individual stability explains a significant amount of the variance on infant sleep-wake behaviors over the first six months of life.
