Mother-infant interaction and infant development in women at risk of postpartum psychosis with and without a postpartum relapse.

BACKGROUND: This study aimed to investigate mother-infant interaction and infant development in women at-risk of postpartum psychosis (PP), with and without a postpartum relapse. METHODS: 103 women (and their offspring) were included, 43 at-risk-of-PP because of a diagnosis of bipolar disorder, schizoaffective disorder or previous PP, and 60 with no current/previous mental illness or family history of PP. Of the at-risk women, 18 developed a psychiatric relapse within 4 weeks after delivery (AR-unwell), while 25 remained symptom-free (AR-well). Mother-infant interaction was assessed using the CARE-Index at 8 weeks' and 12 months' postpartum and infant development using the Bayley-III at 12 months' postpartum. RESULTS: Women at-risk-of-PP as a group, regardless of whether they developed a psychiatric relapse within 4 weeks after delivery, had less synchronous mother-infant interactions and had infants with less optimal cognitive, language, motor and socio-emotional development than healthy controls. In particular, boys of at-risk women had the lowest scores in cognitive, language and motor development and in mother-infant interaction, while girls of the at-risk women had the lowest scores in socio-emotional development. The synchrony in the dyad predicted infant cognitive and language development. There was no evidence for a difference in mother-infant interaction nor in infant development between the AR-unwell and AR-well groups. CONCLUSIONS: These results suggest that, while there is a lack of evidence that an early postpartum relapse in women at-risk-of-PP could represent a risk for the infant per se, maternal risk for PP may be associated with less optimal mother-infant interaction and infant development.

Women with depression in pregnancy or a history of depression have decreased quality of mentalization in the speech to their infants.

BACKGROUND: Our study aims to understand whether depression, either in pregnancy or lifetime, affects cognitive biases (comprising the attentional focus and affective state) and mentalizing features (ability to understand children's internal mental states, thereby detecting and comprehending their behavior and intention), in maternal speech during mother-infant interaction in the first postnatal year. METHODS: We recruited 115 pregnant women (44 healthy, 46 with major depressive disorder [MDD] in pregnancy, and 25 with a history of MDD but healthy pregnancy) at 25 weeks' gestation. Three-minute videos were recorded at 8 weeks and 12 months postnatally for each dyad. Maternal speech was transcribed verbatim and coded for cognitive biases and mentalizing comments using the Parental Cognitive Attributions and Mentalization Scale (PCAMs). RESULTS: Women suffering from antenatal depression showed a decreased proportion of mentalizing comments compared with healthy women, at both 8 weeks (0.03 ± 0.01 vs. 0.07 ± 0.01, P = 0.002) and 12 months (0.02 ± 0.01 vs. 0.04 ± 0.01, P = 0.043). Moreover, compared with healthy women, both those with antenatal depression and those with a history of depression showed decreased positive affection in speech (0.13 ± 0.01 vs. 0.07 ± 0.01 and 0.08 ± 0.02, respectively P = 0.003 and P = 0.043), and made significantly fewer comments focused on their infants' experience at 8 weeks (0.67 ± 0.03 vs. 0.53 ± 0.04 and 0.49 ± 0.05, respectively P = 0.015 and P = 0.005). In linear regression models women's socioeconomic difficulties and anxiety in pregnancy contribute to these associations, while postnatal depression did not. CONCLUSIONS: Both antenatal depression and a lifetime history of depression are associated with a decreased quality of women's speech to their infants, as shown by less focus on their infant's experience, decreased positive affection, and less able to mentalize. Examining maternal speech to their infants in the early postnatal months may be particularly relevant to identify women who could benefit from strategies addressing these aspects of the interactive behavior and thus improve infant outcome in the context of depression.

The impact of gestational diabetes mellitus on perceived mother-infant bonding: a qualitative study.

BACKGROUND: The prevalence of gestational diabetes mellitus (GDM) is rapidly increasing. It is associated with adverse physical and mental health outcomes for women and their babies. Mother-infant bonding is important for maternal health and infant development, but the effect of GDM on mother-infant bonding has not been examined. OBJECTIVE: To explore and describe the impact of GDM on perceived mother infant-bonding in the antenatal and postnatal period. METHODS: Qualitative, individual, semi-structured interviews were conducted with 33 women from diverse backgrounds with current or previous GDM. Data were analysed using reflexive inductive thematic analysis. RESULTS: Three main themes were generated from the analysis: 1) Concern for baby's health and its impact on bonding; 2) GDM management, the pregnancy experience, and bonding; 3) Continuity and discontinuity of the impact on bonding between the antenatal and postnatal periods. CONCLUSION: It was found that GDM can have both positive and negative impacts on perceived mother-infant bonding, which appear to change over the course of the perinatal period. Further observational research is needed to assist in understanding the impact of GDM on mother-infant bonding and the potential mediating effect of mental disorders, including depression.

Effectiveness and cost-effectiveness of psychiatric mother and baby units: quasi-experimental study.

BACKGROUND: Psychiatric mother and baby units (MBUs) are recommended for severe perinatal mental illness, but effectiveness compared with other forms of acute care remains unknown. AIMS: We hypothesised that women admitted to MBUs would be less likely to be readmitted to acute care in the 12 months following discharge, compared with women admitted to non-MBU acute care (generic psychiatric wards or crisis resolution teams (CRTs)). METHOD: Quasi-experimental cohort study of women accessing acute psychiatric care up to 1 year postpartum in 42 healthcare organisations across England and Wales. Primary outcome was readmission within 12 months post-discharge. Propensity scores were used to account for systematic differences between MBU and non-MBU participants. Secondary outcomes included assessment of cost-effectiveness, experience of services, unmet needs, perceived bonding, observed mother-infant interaction quality and safeguarding outcome. RESULTS: Of 279 women, 108 (39%) received MBU care, 62 (22%) generic ward care and 109 (39%) CRT care only. The MBU group (n = 105) had similar readmission rates to the non-MBU group (n = 158) (aOR = 0.95, 95% CI 0.86-1.04, P = 0.29; an absolute difference of -5%, 95% CI -14 to 4%). Service satisfaction was significantly higher among women accessing MBUs compared with non-MBUs; no significant differences were observed for any other secondary outcomes. CONCLUSIONS: We found no significant differences in rates of readmission, but MBU advantage might have been masked by residual confounders; readmission will also depend on quality of care after discharge and type of illness. Future studies should attempt to identify the effective ingredients of specialist perinatal in-patient and community care to improve outcomes.

Increased maternal inflammation and poorer infant neurobehavioural competencies in women with a history of major depressive disorder from the psychiatry research and motherhood - Depression (PRAM-D) study.

INTRODUCTION: Stress in pregnancy is associated with adverse outcomes in offspring, and developmental programming is a potential mechanism. We have previously shown that depression in pregnancy is a valid and clearly defined stress paradigm, and both maternal antenatal and offspring stress-related biology is affected. This study aims to clarify whether maternal biology in pregnancy and offspring outcomes can also be influenced by a history of a prior depression, in the absence of depression in pregnancy. Our primary hypothesis is that, similarly to women with depression in pregnancy, women with a history of depression but who are not depressed in pregnancy will have increased cortisol secretion and markers of immune system function, and that their offspring will have poorer neuro-developmental competencies and increased cortisol stress response. METHODS: A prospective longitudinal design was used in 59 healthy controls and 25 women with a past history of depression who were not depressed in pregnancy, named as 'history-only', and their offspring. Maternal antenatal stress-related biology (cortisol and markers of immune system function) and offspring outcomes (gestational age at birth, neonatal neurobehaviour (Neonatal Behavioural Assessment Scale, NBAS), cortisol stress response and basal cortisol at 2 and 12 months) and cognitive, language and motor development (Bayley Scales of Infant and Toddler Development (BSID)) were measured. RESULTS: Compared with healthy pregnant women, those with a history of depression who remain free of depression in pregnancy exhibit increased markers of immune system function in pregnancy: IL-8 (d = 0.63, p = 0.030), VEGF (d = 0.40, p = 0.008) and MCP-1 (d = 0.61, p = 0.002) and have neonates with lower neurobehavioural scores in most areas, reaching statistical significance in thesocial-interactive (d = 1.26, p = 0.015) cluster. However, there were no differences in maternal or offspring HPA axis function or in infant development at 12 months. CONCLUSION: Our study indicates that pregnant women with a history of depression have increased markers of immune system function, and their offspring show behavioural alterations that may be the effects of in utero programming, epigenetic factors or genetic predisposition.

Fear of childbirth during pregnancy: associations with observed mother-infant interactions and perceived bonding.

Fear of childbirth (FOC) is a common phenomenon that can impair functioning in pregnancy but potential longer term implications for the mother-infant relationship are little understood. This study was aimed at investigating postpartum implications of FOC on the mother-infant relationship. A UK sample of 341 women in a community setting provided data on anxiety, mood and FOC in mid-pregnancy and subsequently completed self-report measures of postnatal bonding in a longitudinal cohort study. Postnatal observations of mother-infant interactions were collected and rated for a subset of 141 women. FOC was associated with maternal perception of impaired bonding, even after controlling for sociodemographic factors, concurrent depression and the presence of anxiety disorders (Coef = 0.10, 95% CI 0.07-0.14, p < 0.001). Observed mother-infant interactions were not associated with FOC (Coef = -0.01-0.03 CI - 0.02 to 0.02, p = 0.46), weakly with concurrent depression (Coef = - 0.10, CI - 0.19 to 0.00, p = 0.06) and not associated with anxiety disorders. The self-efficacy component of FOC was most strongly associated with lower reported bonding (Coef 0.37, 95% CI 0.25-0.49, p < 0.001) FOC makes a distinct contribution to perceived postpartum bonding difficulties but observed mother-infant interaction quality was not affected. This may be due to low self-efficacy impacting psychological adjustment during pregnancy. Targeted interventions during pregnancy focusing both on treatment of key childbirth fears and bonding could help women adjust earlier.

Maternal personality traits, antenatal depressive symptoms and the postpartum mother-infant relationship: a prospective observational study.

PURPOSE: Maternal depression has been associated with bonding difficulties and lower maternal sensitivity in observed mother-infant interactions. However, little research has examined the impact of disordered personality traits in mothers on these outcomes. We investigated the association between disordered personality traits in mothers measured during pregnancy and postnatal (a) self-reported bonding with infant; (b) observational mother-infant interactions. METHODS: Five hundred fifty-six women were recruited during early pregnancy and subsequently followed up at mid-pregnancy (approximately 28 weeks' gestation) and when infants were aged approximately 3 months (n = 459). During early pregnancy, data were collected on disordered personality traits (using the Standardised Assessment of Personality Abbreviated Scale) and depressive symptoms (using the Edinburgh Postnatal Depression Scale). At 3 months postpartum, self-reported perceived bonding (using the Postpartum Bonding Questionnaire) were collected. A sub-sample of women additionally provided observational mother-infant interaction data (n = 206) (coded using the Child-Adult Relationship Experimental Index). RESULTS: Higher disordered personality traits was not associated with maternal perceptions of bonding impairment, but was associated with reduced maternal sensitivity during observational mother-infant interactions [adjusted for age, education, having older children, substance misuse prior to pregnancy, infant sex and gestational age: coefficient = - 0.28, 95% CI = - 0.56 to - 0.00, p < 0.05]. After adjusting for depressive symptoms, the association was attenuated [coefficient = - 0.19, 95% CI = - 0.48 to 0.11, p = 0.217]. CONCLUSIONS: Mothers with disordered personality traits did not perceive themselves as having bonding impairments with their infants but were less sensitive during observed interactions, though depressive symptoms attenuated this relationship. Both depression and disordered personality traits need to be addressed to optimize mother-infant interactions.

Association between maternal childhood trauma and offspring childhood psychopathology: mediation analysis from the ALSPAC cohort.

BackgroundStudies have shown that a mother's history of childhood maltreatment is associated with her child's experience of internalising and externalising difficulties.AimsTo characterise the mediating pathways that underpin this association.MethodData on a mother's history of childhood maltreatment, depression during pregnancy, postnatal depression, maladaptive parenting practices and her child's experience of maltreatment and internalising and externalising difficulties were analysed in an Avon Longitudinal Study of Parents and Children (ALSPAC) sample of 9397 mother-child dyads followed prospectively from pregnancy to age 13.ResultsMaternal history of childhood maltreatment was significantly associated with offspring internalising and externalising difficulties. Maternal antenatal depression, postnatal depression and offspring child maltreatment were observed to significantly mediate this association independently.ConclusionsPsychological and psychosocial interventions focused around treating maternal depression, particularly during pregnancy, and safeguarding against adverse childhood experiences could be offered to mothers with traumatic childhood histories to help protect against psychopathology in the next generation.

Neurobehavioural and cognitive development in infants born to mothers with eating disorders.

INTRODUCTION: Although recent research has focused on the effects of maternal eating disorders (EDs) on children, little is known about the effect of maternal EDs on neurobiological outcomes in newborns and infants. This study is the first to investigate neurobehavioural regulation and cognitive development in newborns and infants of mothers with EDs. METHODS: Women with an active and past ED and healthy controls were recruited to a prospective longitudinal study during their first trimester or second trimester of pregnancy. Newborns and infants of mothers with ED were compared with newborns and infants of healthy controls on (a) neurobehavioural dysregulation using the Brazelton Neonatal Behavioural Assessment Scale at 8 days postpartum (active ED, n = 15; past ED, n = 20; healthy controls, n = 28); and (b) cognitive development using the Bayley Scales of Infant and Toddler Development at 1-year postpartum (active ED, n = 18; past ED, n = 19; healthy controls, n = 28). In order to maintain the largest possible sample at each time point, sample size varied across time points. RESULTS: Newborns of mothers with an active ED had worse autonomic stability when compared with newborns of healthy controls [B = -0.34 (-1.81, -0.26)]. Infants of mothers with a past ED had poorer language [B = -0.33 (-13.6, -1.9)] and motor development [B = -0.32 (-18.4, -1.3)] compared with healthy controls. CONCLUSIONS: Children of mothers with ED display neurobehavioural dysregulation early after birth and poorer language and motor development at 1 year. These characteristics suggest evidence of early neurobiological markers in children at risk. Differential outcomes in children of women with active versus past ED suggest that active symptomatology during pregnancy might have an effect on physiological reactivity while cognitive characteristics might be more stable markers of risk for ED.

Proof of concept of a mind-mindedness intervention for mothers hospitalized for severe mental illness.

Studies 1 and 2 investigated how maternal severe mental illness (SMI) related to mothers' mind-mindedness (appropriate and nonattuned mind-related comments). Study 1 showed that mothers with SMI (n = 50) scored lower than psychologically well mothers for both appropriate and nonattuned comments, whereas mothers with SMI in Study 2 (n = 22) had elevated levels of nonattuned comments. Study 2 also tested the efficacy of a single-session video-feedback intervention to facilitate mind-mindedness in mothers with SMI. The intervention was associated with a decrease in nonattuned comments, such that on discharge, mothers did not differ from psychologically well controls. Study 3 assessed infant-mother attachment security in a small subset of intervention-group mothers from Study 2 (n = 9) and a separate group of standard care mothers (n = 30) at infant mean age 17.1 months (SD = 2.1). Infants whose mothers completed the intervention were more likely to be securely attached and less likely to be classified as insecure-disorganized than those of mothers who received standard care. We conclude that a single session of video-feedback to facilitate mind-mindedness in mothers with SMI may have benefits for mother-infant interaction into the second year of life.

HISTORY OF CHILDHOOD ABUSE AND MOTHER-INFANT INTERACTION: A SYSTEMATIC REVIEW OF OBSERVATIONAL STUDIES.

Literature that has examined maternal self-reported history of abuse and an observational assessment of infant-mother interaction were reviewed. Electronic databases were searched, and studies that met predefined criteria were included. Fourteen (12 independent samples) studies were included and assessed for quality using the Effective Public Health Practice Project tool (National Collaborating Centre for Methods and Tools, 2008). Ten of the 14 studies found a direct or an indirect relationship between self-reported abuse and observed caregiving. The small number of studies and variation in sample characteristics and measurement limit conclusions. Of the studies that were rated of the highest quality, there is some consistency showing that the effect of maternal abuse history on caregiving may be via a third variable (i.e., stress reactivity or depressive symptoms). The current review discusses strengths and limitations of the existing literature and offers suggestions for future research.

Differential effects of ethnic density on the risk of postnatal depression and personality dysfunction.

BACKGROUND: The relationship between ethnic density and psychiatric disorder in postnatal women in the UK is unclear. AIMS: To examine the effect of own and overall ethnic density on postnatal depression (PND) and personality dysfunction. METHOD: Multilevel analysis of ethnically mixed community-level data gathered from a sample of 2262 mothers screened at 6 weeks postpartum for PND and personality dysfunction. RESULTS: Living in areas of higher own ethnic density was protective against screening positive for PND in White women (z = -3.18, P = 0.001), even after adjusting for area level deprivation, maternal age, relationship status, screening positive for personality dysfunction, parity and geographical clustering (odds ratio (OR) 0.98 (95% CI 0.96-0.99); P = 0.002), whereas the effect on personality dysfunction (z = -2.42, P = 0.016) was no longer present once the effect of PND was taken into account (OR = 0.99 (95% CI 0.90-1.0); P = 0.13). No overall ethnic density effect was found for women screening positive for PND or personality dysfunction. CONCLUSIONS: In White women, living in areas of higher own ethnic density was protective against developing PND.

Maternal depression during pregnancy and offspring depression in adulthood: role of child maltreatment.

BACKGROUND: Studies have shown that maternal depression during pregnancy predicts offspring depression in adolescence. Child maltreatment is also a risk factor for depression. AIMS: To investigate (a) whether there is an association between offspring exposure to maternal depression in pregnancy and depression in early adulthood, and (b) whether offspring child maltreatment mediates this association. METHOD: Prospectively collected data on maternal clinical depression in pregnancy, offspring child maltreatment and offspring adulthood (18-25 years) DSM-IV depression were analysed in 103 mother-offspring dyads of the South London Child Development Study. RESULTS: Adult offspring exposed to maternal depression in pregnancy were 3.4 times more likely to have a DSM-IV depressive disorder, and 2.4 times more likely to have experienced child maltreatment, compared with non-exposed offspring. Path analysis revealed that offspring experience of child maltreatment mediated the association between exposure to maternal depression in pregnancy and depression in adulthood. CONCLUSIONS: Maternal depression in pregnancy is a key vulnerability factor for offspring depression in early adulthood.

Neurodevelopmental outcome for offspring of women treated for antenatal depression: a systematic review.

The aim of this systematic review is to appraise existing literature on the effects of treatments for antenatal depression on the neurodevelopment outcomes of the offspring. We conducted a systematic review of the literature to identify studies on different kinds of treatments for antenatal depression (antidepressants and alternative therapies) and their effects on infants' neurodevelopment. After reading the title, abstract, or full text and applying exclusion criteria, a total of 22 papers were selected. Nineteen papers studied the effects of antidepressant drugs, one on docosahexanoic acid (DHA) (fish oil capsules) and two on massage therapy; however, no studies used a randomized controlled design, and in most studies, the control group comprise healthy women not exposed to depression. Comparisons between newborns exposed to antidepressants in utero with those not exposed showed significant differences in a wide range of neurobehavioral outcomes, although in many cases, these symptoms were transient. Two studies found a slight delay in psychomotor development, and one study found a delay in mental development. Alternative therapies may have some benefits on neurodevelopmental outcomes. Our review suggests that antidepressant treatment may be associated with some neurodevelopmental changes, but we cannot exclude that some of these effects may be due to depression per se.

Antenatal depression and offspring psychopathology: the influence of childhood maltreatment.

BACKGROUND: Antenatal depression and childhood maltreatment have each been associated with offspring psychopathology, but have never been examined in the same sample. AIMS: To determine whether childhood maltreatment influences the association between antenatal depression and offspring psychopathology. METHOD: Prospectively collected data on antenatal depression, offspring maltreatment (age 11) and offspring psychopathology (age 11 and 16) were analysed in 120 mother-offspring dyads from the community-based South London Child Development Study. RESULTS: Antenatal depression increased the risk of maltreatment in the offspring by almost four times. Children exposed only to antenatal depression or only to childhood maltreatment were no more at risk of developing psychopathology; however, children exposed to both antenatal depression and childhood maltreatment were at almost 12 times greater risk of developing psychopathology than offspring not so exposed. CONCLUSIONS: Research investigating exposure to adverse events in utero and offspring psychopathology should take account of postnatal adverse events such as maltreatment.

The association between maternal lifetime interpersonal trauma experience and perceived mother-infant bonding.

BACKGROUND: Interpersonal traumas are common among expectant and new mothers and are found to have considerable impacts on women's mental health. These experiences may disrupt maternal perceptions of the mother-infant relationship, which is essential for healthy infant development, but findings are inconsistent. This study aims to explore associations between lifetime interpersonal traumas and their impact on self-reported mother-infant bonding. METHODS: Secondary data analysis of a representative cohort of 453 women attending at a South London maternity service. Lifetime interpersonal trauma experience and its association with self-reported mother-infant bonding (Postpartum Bonding Questionnaire) was assessed in uni- and multivariable linear regressions, the latter adjusted to account for antenatal depressive and posttraumatic symptoms, measured using the Edinburgh Postnatal Depression Scale and Posttraumatic Stress Disorder Scale, and key sociodemographic risk factors. RESULTS: Maternal lifetime trauma was not associated with perceived difficulties in mother-infant bonding at three months postnatal; however antenatal depressive symptoms, both with continuous EPDS score (0.33, 95% CI 0.17-0.50, p<0.001) and clinical cut-off ≥13 (4.26, 95% CI 2.02-6.49, p<0.001) were associated with self-reported bonding difficulties. LIMITATIONS: The composite trauma measurement did not allow for a comprehensive assessment of individual trauma types. CONCLUSIONS: There was no evidence for a link between maternal lifetime trauma experiences and self-reported bonding difficulties. However, an association between antenatal depressive symptoms and perceived postpartum bonding impairment was found. This highlights the importance of identification and treatment of depressive symptoms during pregnancy and offering women support in facilitating a positive mother-infant relationship.
