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.     

The effect of preterm birth on infant negative affect and maternal postpartum depressive symptoms: A preliminary examination in an underrepresented minority sample

ObjectiveTo examine the effect of preterm birth on maternal postpartum depressive symptoms and infant negative affect in an underrepresented minority sample.MethodParticipants were 102 mothers and their 3- to 10-month-old infants. Mothers completed the Edinburgh Postnatal Depression Scale and the Infant Behavior Questionnaire-Revised.ResultsRelative to normative samples, the current underrepresented minority sample of mostly Hispanics and Blacks displayed high rates of preterm birth (30%) and maternal postpartum depressive symptoms (17%). Preterm birth had a significant direct effect on postpartum depressive symptoms and infant negative affect. Additionally, there was an indirect effect of postpartum depressive symptoms on the relation between preterm birth and infant negative affect. Specifically, lower birth weight and gestational age predicted higher levels of depressive symptoms in the mother, and higher levels of depressive symptoms in the mother, in turn, predicted higher levels of infant negative affect.ConclusionFindings emphasize the importance of screening for postpartum depressive symptoms and infant negative affect among mothers and their preterm infants, especially among families from underrepresented minority backgrounds.     

The role of cognitive factors in the pathogenesis of obsessive-compulsive symptoms: a prospective study

Cognitive models of obsessive-compulsive disorder (OCD) posit that specific kinds of dysfunctional beliefs (e.g., pertaining to responsibility and the significance of intrusive thoughts) underlie the development of this disorder. The present study was designed to prospectively evaluate whether dysfunctional beliefs thought to underlie OCD act as a specific vulnerability factor in the pathogenesis of obsessive-compulsive symptomatology. Eighty-five individuals were prospectively followed over a period of time thought to be associated with an increased onset of OCD symptoms -- childbirth and the postpartum. The majority of these new mothers and fathers experienced intrusive infant-related thoughts and performed neutralizing behaviors similar to, but less severe than, those observed in OCD. Scores on a measure of dysfunctional beliefs thought to underlie OCD predicted the development of obsessive-compulsive symptoms after controlling for pre-existing OCD symptoms, anxiety, and depression. Dysfunctional beliefs also predicted the severity of checking, washing, and obsessional OCD symptom dimensions, but not neutralizing, ordering, or hoarding symptom dimensions. These data provide evidence for specific dysfunctional beliefs as risk factors in the development of some types of OCD symptoms.     

Maternal-infant bonding and partner support during pregnancy and postpartum: Associations with early child social-emotional development

The first 1000 days after conception are considered critical for healthy development and well-being throughout life. Fundamental to health practices during pregnancy and positive parenting after birth is the development of maternal-infant bonding. Previous research has demonstrated the importance of having an involved partner during pregnancy and in parenting for optimal maternal-infant bonding. The current study examined maternal-infant bonding and partner support during pregnancy and the postpartum period, and their associations with early child social-emotional development. A total of 227 women completed the Pre- and Postnatal Bonding Scale (PPBS) and Tilburg Pregnancy Distress Scale (TPDS) during pregnancy (32 weeks of gestation) and at 8 months postpartum, assessing maternal-infant bonding and partner support. Additionally, a questionnaire on social-emotional behavior of the Bayley Scales of Infant and Toddler Development was administered to mothers to measure child development at 2 years of age. Path analyses revealed an indirect positive effect of prenatal maternal-infant bonding on child social-emotional development through postnatal maternal-infant bonding, as well as mediating effects of pre- and postnatal maternal-infant bonding on the association between pre- and postnatal partner support and child social-emotional development. Our findings support the notion that an emotional connection from mother to child originates in pregnancy and that experiencing positive feelings towards the fetus promotes positive maternal-infant bonding after birth and social-emotional capacities of the child. Additionally, having a supportive partner during pregnancy and postpartum, might be essential for the development of optimal maternal-infant bonding.     

Postpartum depression: Proposal for prevention through an integrated care and support network

Social science research and clinical literature concur with our experience as providers of psychoeducational and clinical services: Postpartum depression results from the interplay of a multitude of individual and contextual factors. In light of the extensive literature on postpartum depression, it is surprising that models for prevention have not been established. We propose a model for prevention through integrated care and support, in which a wide range of existing services are used. This model is similar to comprehensive prevention models proposed by advocates of integrated service systems, such as community mental health and family support. The article includes illustrative case material.     

Does Postpartum Depression Affect Parental Embodied Mentalizing in Mothers With 4-Months old Infants?

Parental Embodied Mentalizing (PEM) regards parents’ nonverbal capacity to understand the infant’s bodily manifested mental states and adjust his or her own movements accordingly. Little is known about how mothers suffering from postpartum depression (PPD) mentalize the infant on an embodied level. The aims of the present study were to investigate whether mothers meeting criteria for a PPD diagnosis differ from non-clinical mothers in regard to their PEM capacities and whether the severity of depressive symptoms was associated with PEM in mothers meeting criteria for a PPD diagnosis compared to non-clinical mothers.10-minute long lab-based face-to-face interactions were coded with the PEM coding scheme at 4-months postpartum in mother-infant dyads with mothers meeting criteria for a PPD diagnosis (n = 29) and non-clinical mothers (n = 51).Results showed that mothers with and without a PPD diagnosis differ in their capacity to mentalize on an embodied level, but only when controlling for scores on the Edinburgh Postnatal Depression Scale (EPDS). However, more depressive symptoms as measured with the EPDS was not in itself associated with lower PEM in either group. This finding may indicate the presence of a threshold effect, i.e. that maternal PEM may be affected only when a certain degree of severity and duration in depressive symptoms is beyond a certain threshold. The importance of the findings in regard to the assessment of depression as well as more clinical perspectives are discussed.     

Postpartum mood disorders: Results of an online survey

Purpose: Postpartum mood disorders (PMDs), the distressing mental and emotional symptoms experienced by women after childbirth, are just now receiving the attention they warrant. Given the serious and sometimes life‐threatening nature of PMDs, we used a qualitative research design to examine more closely the nature of symptoms experienced and the effective strategies women used to cope with PMD. Participants: The respondents were 252 members of PMD and breast‐feeding (La Leche League) support groups throughout the United States. Method: Participants responded anonymously to open‐ended questions in an online survey. The data were reviewed by the research team to determine common themes and prevailing issues. Results: Participants reported myriad different symptoms and used a host of various strategies to alleviate problematic thoughts, feelings, and behaviours following childbirth. Postpartum symptoms affected participants’ plans to have future children. For some women, symptoms became more intense during subsequent births. Despite the problematic nature of PMD, more than half of the participants reported receiving little or no information from healthcare providers about PMDs. Implications for counsellors and other healthcare providers are discussed in detail.     

Assessing postpartum depression: Evidences for the need of multiple methods

IntroductionDifferent methods and instruments are frequently used to measure postpartum depression (PPD) in research, e.g. PPD-specific scales, DSM-based diagnostic interviews and rating scales assessing general depression. However, it is unsure whether these measures would lead to the same results, e.g. in the identification of “depressed” women or in their relations to third variables.Objective(s)We compared different measures of PPD and their relations with a third variable, namely the mothers’ marital satisfaction.MethodWe recruited 65 mothers to take part in a study about the impact of PPD on the development of early family relations. Maternal PPD was assessed with multiple methods (i) a PPD-specific scale, (ii) a DSM-based diagnostic interviews and (iii) a rating scale designed to assess the severity of depressive symptoms. We assessed mothers’ marital satisfaction with the Marital Adjustment Test (MAT).ResultsResults showed weak overlap between PPD-specific scale and DSM-based diagnosis of PPD, and modest correlations between the PPD-specific scale and the general depression rating scale. Only the score on the PPD-specific scale could predict marital satisfaction.ConclusionAs we found discrepancies between different measures of PPD, we suggest being cautious in the choice of measures and using multiple methods to measure PPD in a comprehensive way.     

Maternal postpartum depressive symptoms and infant externalizing and internalizing behaviors

Maternal postpartum depression has been shown to be one of the main predictors of externalizing and internalizing behaviors in toddlers and adolescents. Research suggests that presence of such behaviors can be observed as early as infancy. The current study uses longitudinal data from 247 mothers to examine the relationship between postpartum depressive symptoms at 8 weeks and the infant's externalizing and internalizing behaviors at 12 months. In unadjusted linear regression models, there were associations between postpartum depressive symptoms and infant externalizing behaviors (β = 0.082, SE = 0.032, p = 0.012) and internalizing behaviors (β = 0.111, SE = 0.037, p = 0.003). After controlling for potential confounding factors, including maternal age, race, education, home ownership, smoking status in the postpartum period, marital status, parenting stress, and happiness from becoming a parent, the associations between postpartum depressive symptoms and infant externalizing (β = 0.051, SE = 0.034, p = 0.138) and internalizing behaviors (β = 0.077, SE = 0.040, p = 0.057) were reduced and became non-significant. Furthermore, in these models the total amount of variance explained was 17.2% (p < 0.0001) for externalizing behaviors and 10.5% (p < 0.01) for internalizing behaviors; the only significant predictor of externalizing behaviors was maternal age (β = −0.074, SE = 0.030, p = 0.014), and of internalizing behaviors was white non-Hispanic ethnicity (β = −1.33, SE = 0.378, p = 0.0005). A combined effect of the confounding factors seems to explain the finding of no significant independent association between postpartum depressive symptoms and infant externalizing and internalizing behaviors.     

Infant interest in their mother's face is associated with maternal psychological health

Early experience can alter infants’ interest in faces in their environment. This study investigated the relationship between maternal psychological health, mother–infant bonding, and infant face interest in a community sample. A visual habituation paradigm was used to independently assess 3.5-month old infants’ attention to a photograph of their mother's face and a stranger's face. In this sample of 54 healthy mother–infant pairs, 57% of mothers (N = 31) reported symptoms of at least one of stress response to trauma, anxiety, or depression. Interest in the mother-face, but not stranger-face, was positively associated with the mother's psychological health. In regression analyses, anxiety and depression predicted 9% of the variance in looking to the mother-face. Anxiety was the only significant predictor within the model. No direct associations were found between mother–infant bonding and infants’ face interest. Taken together, these findings indicate that infant's visual engagement with their mother's face varies with maternal symptoms of emotional distress, even within a community sample.
