Infants of depressed mothers show less “depressed” behavior with their nursery teachers

This study investigated whether infants' “depressed” behavior (i.e., less positive affect and lower activity levels) noted during their interactions with their depressed mothers generalized to their interactions with their nondepressed nursery teachers. Field et al. (1988) reported that infants of depressed mothers also show “depressed behavior” when interacting with nondepressed female adults, suggesting that the infants develop a generalized “depressed mood style” of interaction. However, in that study the adults were also strangers to the infants, confounding the results. In the present study, eighteen 3-month-old infants interacted with their depressed mothers and also with their nondepressed familiar teachers in 3-minute episodes. The infants' behavior ratings improved when they interacted with their familiar teachers compared to their interactions with their mothers. The infants' low activity levels and negative affect were specific to their interactions with their depressed mothers. Thus, the data suggest that the infants respond differentially to depressed and nondepressed adults who are familiar.     

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.     

Depressed fathers' stereotyping of infants labeled “depressed”

This study investigated whether depressed and nondepressed fathers stereotyped infants labeled “depressed” and how they viewed their own infants. Twenty-five fathers (12 nondepressed, 13 depressed) of 4-month old infants rated their infants' psychological, social and physical attributes on the Infant Stereotyping Scale (ISS). They then rated videotaped infants, labeled “normal” or “depressed”, on the ISS. Fathers rated depressed versus normal infants lower on sociability, social behavior, and cognitive competence. Depressed versus nondepressed fathers, rated depressed infants lower on social behavior, potency, and sociability. Depressed fathers rated their own infants lower on social behavior, potency, and cognitive competence as well as being more vulnerable. Implications of parental depression on stereotyping effects and possible risks for infants are discussed. © 1997 Michigan Association for Infant Mental Health     

The impact of postpartum depressed mood on mother-infant interaction: Like mother like baby?

The purpose of this study was to test the hypothesis that mothers with depressed mood would exhibit less optimal interaction than their nondepressed counterparts and that their infants would show similar deficits in interactional behavior. Twenty-two mothers and their 2-month-old infants were videotaped in to-minute free-play segments in a laboratory playroom, and their interactions were coded using both time-sampling and global clinical ratings of behavior. Mothers with depressed mood were judged significantly lower on overall positive interaction, Expressivity/Affective Involvement, and Responsivity/ Sensitivity than were nondepressed mothers. Infants of mothers with depressed mood were rated significantly lower than infants of nondepressed mothers on corresponding interaction domains. Mothers with depressed mood were also rated as more variable than nondepressed mothers along a continuum of withdrawal to controlling/intrusive behavior. Contrary to prediction, level of maternal stimulation and infant activity did not differ as a function of depression in maternal mood. We conclude that mild to moderate symptoms of maternal depression may have salient but selective effects on mother-infant interaction.     

Depressed mothers' assessments of their neonates' behaviors

Neonates were assessed at delivery and again at 1 month by examiners and by their depressed or nondepressed mothers. Examiner assessments were conducted using the Brazelton Neonatal Behavioral Assessment Scale (NBAS). Maternal assessments were conducted by mothers using a simplified version of the NBAS, the Mother's Assessment of the Behavior of her Infant (MABI). Examiners rated neonates of depressed mothers lower than infants of nondepressed mothers on state organization. At delivery, newborn infants of depressed mothers were given lower state regulation scores by their mothers than by the examiners and, 1 month later, examiners’ state regulation ratings were as negative as those of the depressed mothers. Conversely, infants of nondepressed mothers were given higher social interaction scores by their mothers than by the examiners, and 1 month later, examiner ratings of social interaction were as positive as those of the nondepressed mothers. These findings suggest that infants of depressed mothers may be placed at risk by prenatal influences and by risks associated with maternal perceptions. Perceptions of infants appear to be colored by maternal depression status as early as the immediate postpartum period and, though “subjective,” these perceptions are predictive of infant outcomes.     

Influences of maternal postpartum depression on fathers and on father–infant interaction

Maternal postpartum depression (PPD) has been shown to negatively influence mother–infant interaction; however, little research has explored how fathers and father–infant interaction are affected when a mother is depressed. This study examined the influence of maternal PPD on fathers and identified maternal and paternal factors associated with father–infant interaction in families with depressed as compared with nondepressed mothers. A convenience sample of 128 mother–father–infant triads, approximately half of which included women with significant symptoms of PPD at screening, were recruited from a screening sample of 790 postpartum women. Mothers and fathers completed measures of depression, marital satisfaction, and parenting stress at 2 to 3 months' postpartum and were each videotaped interacting with their infants. Results indicate that maternal PPD is associated with increased paternal depression and higher paternal parenting stress. Partners of depressed women demonstrated less optimal interaction with their infants, indicating that fathers do not compensate for the negative effects of maternal depression on the child. Although mother–infant interaction did not influence father–infant interaction, how the mother felt about her relationship with the infant did, even more so than maternal depression. The links between maternal PPD, fathers, and father–infant interaction indicate a need for further understanding of the reciprocal influences between mothers, fathers, and infants.     

The Effect of Maternal Depressed Mood on Infant Emotional Reaction in a Surprise‐Eliciting Situation

The purpose of this study is to examine the claim that an infant's ability to respond appropriately to an emotional situation varies according to the emotional state of the mother. Surprise expressions in mother and child were examined both in terms of paralinguistic aspects of surprise vocalizations as well as facial expressions. Seventy‐two infants and their mothers (mean age=8 months, range=5–11 months) were video‐ and audiotaped in their homes. Half of the infants, matched for age and gender, had mothers who reported depressed mood. Infants of mothers with depressed mood showed significantly fewer components of facial expressions of surprise compared with infants of nondepressed mothers. Mothers with depressed mood exclaimed surprise with a significantly lower pitch (mean F₀=386.13 Hz ) compared to nondepressed mothers (mean F₀=438.10 Hz ). Furthermore, mothers with depressed mood showed fewer associations between elements of emotional expression than the nondepressed group. Infants' expressions of surprise are influenced by maternal mood, resulting in reduced expression of the emotion in infants of mothers with depressed mood. These results are discussed in terms of coordination of vocal parameters in mother–infant dyadic interaction.     

Interactions between depressed and nondepressed Latina mothers and their premature infants

The impact of depression upon mother–infant interaction was studied longitudinally in a sample of very low income, immigrant Latina mothers with premature, very low birth weight infants. Both maternal characteristics and infant characteristics were examined using a rating scale which measured feeding interactions. Results indicate that mothers who were depressed at one month did not interact differently with their premature infants than nondepressed mothers. In addition, infants of mothers who were depressed at one month did not interact differently with their mothers than infants of nondepressed mothers. There were no differences between groups of mothers who remained depressed across the one-year period and groups whose scores reflected no depression or changes in depression levels. These findings challenge previous assumptions about interactions between depressed mother–infant dyads. Results indicate the need to broaden study attention to include socioeconomic, cultural, and life circumstances of families that may have greater impact on child outcomes than single assessments of maternal depression. Such studies may lead to changes in the way services are delivered and the types of interventions provided to non-mainstream families. © 1997 Michigan Association for Infant Mental Health     

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.     

Cesarean childbirth: Psychological implications for mothers and fathers

Home observations, ratings of interaction, and interviews were carried out in families with first-born 5-month-old infants. Comparisons were made between two groups of families differing as to whether the childbirth had been a Cesarean or vaginal delivery. Fathers whose babies had been born by Cesarean delivery reported greater involvement in child care and were rated as more responsive to infant distress. Both mothers and fathers tended to show less animation in interactions with their infants following a Cesarean delivery: mothers engaged less frequently in vigorous physical stimulation and showed less reciprocal positive affect with their infants, and fathers smiled less at their infants.     

Infants of chronically depressed mothers learn in response to male, but not female, infant-directed speech

Previous research using a conditioned-attention paradigm demonstrated that 4-month-old infants of depressed mothers (a) failed to acquire associations when a segment of their mothers' infant-directed (ID) speech signaled the presentation of a smiling face but (b) did acquire associations when a segment of an unfamiliar nondepressed mother's ID speech signaled the face (P. S. Kaplan, J. -A. Bachorowski, M. J. Smoski, & W. J. Hudenko, 2002). In the present study, 5- to 13-month-old infants of depressed mothers failed to acquire associations when either their own mothers' (Experiment 1) or an unfamiliar nondepressed mother's (Experiments 1 and 2) ID speech signaled a face. However, these infants acquired associations when a segment of an unfamiliar nondepressed father's ID speech served as the signal (Experiment 2). One possible explanation of these results is that infants of depressed mothers selectively "tune out" ID speech from their mothers and from other, nondepressed, women.     

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.     

The early resumption of employment by mothers: Implications for parent-infant interaction

Home observations of mother-father-infant interaction and mother-infant interaction were contrasted in middle-class families in which the mother was employed or a full-time caregiver. First-born infants and their parents were observed at 3 months. The results indicate that when mother, father, and infant were together parents in the single wage-earner families provided more tactile stimulation to their babies; fathers in single wage-earner families tended to interact more with their infants than did mothers, while in dual wage-earner families mothers tended to interact more than fathers; and fathers in single wage-earner families exceeded fathers in dual wage-earner families in interactions with their infants. By contrast, mothers in the two groups showed very little difference in their interactions with their babies. No significant differences were found for maternal behavior in the three-person observation, and a single behavior differentiated between the groups in the mother-baby observation, with homemaker mothers more often making visual contact with their babies. The implications of these findings are discussed, both with respect to further research, and with regards to the development of children of employed mothers.     

Targeting adolescent mothers with depressive symptoms for early intervention

Infants of mothers with depressive symptoms show developmental delays if symptoms persist over the first 6 months of the infant's life, thus highlighting the importance of identifying those mothers for early intervention. In Study 1, mothers with depressive symptoms (n = 160) and mothers without depressive symptoms (n = 100) and their infants were monitored to identify variables from the first 3 months that predict which mothers would still be symptomatic at 6 months. A "dysregulation" profile was noted for the infants of depressed mothers, including lower Brazelton scores, more indeterminate sleep, and elevated norepinephrine, epinephrine, and dopamine levels at the neonatal period, and greater right frontal EEG activation, lower vagal tone, and negative interactions at the 3- and 6-month periods. A group of maternal variables from the neonatal and 3-month assessments accounted for 51% of the variance in the mothers' continuing depressive symptoms. These variables included greater right frontal EEG activation, lower vagal tone, and less positive interactions at 3 months, and elevated norepinephrine, serotonin, and cortisol levels at the neonatal stage. In Study 2, a similar sample of mothers with depressive symptoms (n = 160) and without depressive symptoms (n = 100) was recruited and followed to 3 months. Those symptomatic mothers who had values above (or below) the median (depending on the negative direction) on the predictor variables identified in Study 1 (taken from the first 3 months) were then randomly assigned to an intervention or a control group at 3 months. These groups were then compared with each other, as well as with the group without depressive symptoms, at 6 and 12 months. The intervention, conducted from 3 to 6 months, consisted of free day care for the infants and a rehab program (social, educational, and vocational) plus several mood induction interventions for the mothers, including relaxation therapy, music mood induction, massage therapy, and mother-infant interaction coaching. Although the mothers who received the intervention continued to have more depressive symptoms than did the nondepressed mothers, their interactions significantly improved and their biochemical values and vagal tone normalized. Their infants also showed more positive interations, better growth, fewer pediatric complications, and normalized biochemical values, and by 12 months their mental and motor scores were better than those of the infants in the control group.     

Maternal depression and its relationship to life stress,perceptions of child behavior problems,parenting behaviors,and child conduct problems

This study examined the relationship of reported maternal depression to prior and current life stressors, and to mother perceptions of child adjustment, parenting behaviors, and child conduct problems. Forty-six depressed mothers and 49 nondepressed mothers and their clinic-referred children (aged 3-8 years) participated. Depressed mothers were more critical than nondepressed mothers, but the behavior of children of depressed and nondepressed mothers showed no significant differences. Depressed mothers were more likely to have experience child abuse, spouse abuse, or more negative life events than nondepressed mothers. Maternal reports of stress related to mother characteristics and to negative life events were the most potent variables discriminating depressed from nondepressed mother families.     

Depressed mothers' newborns show longer habituation and fail to show face/voice preference

Twenty neonates of depressed and nondepressed mothers failed to show an initial visual preference for their mother's versus a female stranger's face/voice. Subsequently, infants were habituated to their mother's face and voice. Infants of depressed mothers required 1/3 more trials and almost twice as long to habituate. A posthabituation test with their mother and a different female stranger revealed a preference for the stranger's face for 9 out of the 10 newborns of the nondepressed mothers. Again, the infants of depressed mothers displayed no visual preference. These findings reveal differences in depressed mothers newborns' speed of habituation and face/voice preferences. ©2002 Michigan Association for Infant Mental Health.     

Temporal coordination between maternal looming and infant gaze in depressed and nondepressed dyads: A bootstrapping approach

In this study, we examine the convergent validity of a measure of maternal looming derived using a motion capture system, and the temporal coordination between maternal loom and infant gaze using an event-based bootstrapping procedure. The sample comprised 26 mothers diagnosed with postpartum depression, 43 nondepressed mothers, and their 4-month-old infants. Mother-infant interactions were recorded during a standard face-to-face setting using video cameras and a motion capture system. First, results showed that maternal looming was correlated with a globally coded measure of maternal overriding. Maternal overriding is an intrusive behavior occurring when the mother re-directs the infant’s attention to parent-led activities. Thus, this result confirms that maternal looming can be considered a spatial intrusion in early interactions. Second, results showed that compared to nondepressed dyads, depressed dyads were more likely to coordinate maternal loom and infant gaze in a Loom-in-Gaze-pattern. We discuss the use of automated measurement for analyzing mother-infant interactions, and how the Loom-in-Gaze pattern can be interpreted as a disturbance in infant self-regulation.     

Caregiving behavior and interactions of prenatally depressed mothers (antidepressant‐treated and non‐antidepressant‐treated) during newborn acute pain

This exploratory study aimed to examine time‐based measures of the behaviors and interactions of prenatally depressed serotonin reuptake inhibitors (SRI)‐medicated mothers to their infant's pain (n = 10) by comparing them with similar measures obtained from prenatally depressed nonmedicated mothers and their infants (n = 10), and nondepressed mothers and their infants (n = 10). During the second trimester of their pregnancy, the 30 study mothers were assessed for depression and anxiety, with no further measures of maternal mood taken. Maternal and infant interactions were continuously videorecorded while the infant underwent a scheduled heel lance for routine blood screening that occurred when study infants were between the ages of 24 and 60 hr. Maternal behavior and infant cry, for all 30 cases, were coded second‐by‐second for the full duration of each infant's heel lance using a reliable coding system and analyzed using odds ratio and regression analyses. Infants exposed to prenatal SRIs and depressed maternal mood were more likely to have lower Apgar scores and to exhibit weak and absent cry. Even when duration of the heel lance was controlled for, women with depression during the second trimester were more likely to exhibit depressed behavior at 2 days' postpartum despite sustained SRI antidepressant treatment. Both groups of prenatally depressed mothers were more likely to exhibit diminished response to their infants' pain cue although nonmedicated mothers' expressions of depressed behavior were more similar to healthy controls. Comprehensive understanding is essential to optimize the clinical care of mothers and their infants in this complex setting. This study contributes preliminary new findings that warrant prospective and longitudinal studies to clarify further the impacts of prenatal SRI and maternal mental mood (e.g., chronic depression and anxiety) effects on the mother–infant interaction and infant pain and stress reactivity.     

Object perception in 5-month-old infants of clinically depressed and nondepressed mothers

Five-month-old infants of clinically depressed and nondepressed mothers were familiarized to a wholly novel object and afterward tested for their discrimination of the same object presented in the familiar and in a novel perspective. Infants in both groups were adequately familiarized, but infants of clinically depressed mothers failed to discriminate between novel and familiar views of the object, whereas infants of nondepressed mothers successfully discriminated. The difference in discrimination between infants of depressed and nondepressed mothers is discussed in light of infants' differential object processing and maternal sociodemographics, mind-mindedness, depression, stress, and interaction styles that may moderate opportunities for infants to learn about their world or influence the development of their perceptuocognitive capacities.     

Interaction behavior of infants and their dual-career parents

The behaviors of dual-career parents were compared in face-to-face interactions with their 8-month-old infants who attended on all-day infant nursery. Mothers, as compared to fathers, exhibited more frequent smiling, vocalizing, and touching with their infants. In turn, the infants spent a greater proportion of the interaction time smiling and being motorically active when they were interacting with their mothers versus their fathers.
