Cognitive factors and post-partum depression: What is the influence of general personality traits, rumination, maternal self-esteem, and alexithymia?

Is parental depression related to parental mentalizing? A systematic review and three-level meta-analysis

This systematic review and meta-analysis is aimed to summarize the state of research on the relation between parental depression and parental mentalizing. To account for the multifaceted nature of parental mentalizing, several conceptualizations and measures were included and compared. The last database search was conducted on March 13, 2023. Using three-level meta-analytic modelling, we analyzed a total of 12,665 participants from 63 studies with 233 effect sizes. Taken together, higher depression was only weakly associated with lower mentalizing (r = -0.06). Specifically, parents with higher depression scored lower on questionnaire measures of parental reflective functioning (r = -0.11). No significant correlations were found for interview measures of parental reflective functioning, the observational and interview measure of mind-mindedness, or insightfulness. The data showed substantial heterogeneity. The mean effect size for self-reported pre-mentalizing (r =  -0.23 for reverse-coded subscale scores) was significantly stronger compared to other self-report subscales. In studies including parents with diagnosis and controls, there was limited evidence suggesting a larger negative correlation between depression, mind-mindedness, and insightfulness. Therefore, more research is needed in clinical samples. Due to their correlational nature, our results do not allow causal inferences. Future studies should target moderators that explain variability (e.g., comorbid psychological problems, coparenting, child behavior).

Assessment of Mothers' Mood and Cognition Functions in Perinatal Period and Their Influences on Breastfeeding Success

Aim: In this study, we aimed to examine the effects of peripartum mother's cognitive functioning, anxiety, and postpartum depression of mothers on the practice of exclusive breastfeeding. Material and Method: The pregnant women in the last trimester who were attended in the outpatient department of obstetrics and gynecology were included in the study as the study group. A total of three follow-ups were conducted in the study group. In our study Mini-Mental State Examination (MMSE) was used to assess cognitive functioning, State-Trait Anxiety Inventory (STAI) 1,2 to assess anxiety, Edinburgh Postnatal Depression Scale (EPDS) to assess postpartum depression, Breastfeeding Self-Efficacy Scale (BSES) to assess mother's self- efficacy in breastfeeding, LATCH Breastfeeding Assessment Tool to assess mother's and baby's breastfeeding technique. Results: All of 158 pregnant and 96 non-pregnant women were enrolled in the study. After delivery, there was a significant decrease in STAI 2 scores compared to the prenatal period (p=0.001) and a significant increase in MMSE scores (p=0.001). There was no difference in STAI 1,2 , and MMSE scores between the groups with and without successful breastfeeding (p >0.05). LATCH scores were statistically significantly higher in the group that successfully breastfed (p =0.001). LATCH (r=-0.427, p

Repetitive negative thinking in the perinatal period and its relationship with anxiety and depression

BACKGROUND

Rumination and worry represent two types of repetitive negative thinking (RNT), and their predictive and maintaining roles are well-established in depression and anxiety, respectively. Furthermore, there is an emerging literature on the link between RNT and psychological wellbeing in the perinatal period.

METHODS

We conducted a scoping review of studies that have investigated the relationship between RNT and perinatal depression and anxiety. We identified 87 papers eligible for inclusion in the review; they included cross-sectional and longitudinal studies, as well as treatment evaluations (pilot trials and randomised controlled trials).

RESULTS

Cross-sectional studies provided evidence of an association between RNT (i.e., rumination and worry) and depression and anxiety, in both pregnancy and postpartum. Longitudinal findings were mixed. Whilst antenatal worry consistently predicted subsequent depression and anxiety (both later in pregnancy and postpartum), rumination did not consistently predict depression. However, there was some evidence that rumination interacted with other processes to predict later psychopathology. Three randomised controlled trials evaluated whether psychological treatments reduce RNT in the perinatal period, only one of which included a clinical sample.

LIMITATIONS

No experimental investigations were eligible for inclusion in the review.

CONCLUSIONS

Further studies are needed to further our understanding of the nature and role of RNT in pregnancy and postpartum, and its consequences for maternal mental health. These include (but are not limited to) experimental investigations, studies with large clinical samples, and RCTs evaluating the effectiveness of psychological interventions targeting RNT to prevent and treat perinatal depression and anxiety.

Computer-based mother-infant interaction analysis and mental functioning in postpartum depression

BACKGROUND

Among mothers suffering from postpartum depression (PD), 10-13% additionally experience a mother-infant interaction disturbance that causes a severe mental health risk for the infant. Besides depressive symptomology, the underlying factors promoting dysfunctional maternal interaction behavior have not yet been sufficiently investigated. Therefore, we examined potential relationships between computer-based mother-infant interaction among postpartum depressed dyads and maternal mental functioning.

METHODS

Mother-infant interaction was video-recorded and evaluated via a computer-based micro-interaction analysis program (INTERACT). We included only 25 hospitalized mother-infant dyads that fulfilled the diagnostic criteria of PD and tested mothers on their mental functioning (empathy, theory of mind, meta-cognition and alexithymia).

RESULTS

Behavioral interaction analyses indicated that mothers with PD were prone to inactive maternal behavior, less positive maternal behavior along with more rejective behavior and also disengaged affect towards the infant. Distortions in mothers' mental functioning may have had an influence on the dysfunctional patterns of mother-infant dyads.

CONCLUSIONS

Cognitive and social functioning could be an influencing factor on dysfunctional maternal interaction behavior. Early detection of distortions of mental processing in expectant mothers might help to inhibit the clinical manifestation of dysfunctional mother-infant bonding and negative child outcome in PD.

Capacities for meta-cognition, social cognition, and alexithymia in postpartum depression

Postpartum depression (PPD), a female-specific disorder, is the most common medical complication associated with childbirth (10-20%). The pathological relevance of emotion processing, meta-cognition, alexithymia, and social cognition to PPD is unclear. We tested 25 mothers with PPD (mean age: 30.72 ± 5.76 years) and 25 healthy mothers (mean age: 32.03 ± 3.54 years) for alexithymia (Toronto Alexithymia Scale) and evaluated cognitive empathy (Faux Pas Test), affective empathy (Interpersonal Reactivity Index), meta-cognition (Meta-Cognitions Questionnaire), sociodemographic and clinical-psychometric characteristics and personality dimensions. Mothers with PPD showed higher levels of neuroticism and more anxiety-depressive characteristics. Their metacognitive abilities were significantly altered and they more often had alexithymia. Significant correlations between alexithymia and meta-cognition, trait anxiety, and neuroticism were found. Alexithymia, neurotic personality traits, and dysfunctional meta-cognition appear more frequently in PPD women than healthy women. Social cognition abilities were not significantly altered. Alexithymia and metacognitive distortions play important roles in the pathogenesis of PPD. Dysfunctional meta-cognition, neuroticism, and alexithymia may be risk factors that should be detected early in expectant mothers to prevent the development of PPD.

Personality traits as a risk factor for postpartum depression: A systematic review and meta-analysis

BACKGROUND

Certain personality traits increase vulnerability to depression, but the evidence linking personality and postpartum depression (PPD) is less robust. This systematic review aimed to identify personality traits that increase the risk of PPD.

METHODS

We systematically reviewed studies retrieved from PubMed/Medline, PsycINFO, Scopus, CINAHL, and Cochrane, following the PRISMA guidelines for reporting. We carried out a meta-analysis on the association between neuroticism and PPD.

RESULTS

A total of 34 studies were analyzed. Of these, 31 considered at least one trait associated with PPD; 10 studies considered at least one trait not associated with PPD. The meta-analysis included 13 studies, concluding that neuroticism was associated with PPD (OR: 1.37; 95%CI: 1.22-1.53; p<0.001).

LIMITATIONS

Study design and approach to personality assessment influence results. Prospective longitudinal studies of persons with no prior history of mood disorder would provide stronger evidence about whether particular personality traits predict PPD. Most studies reviewed used self-report measures to assess personality. Study design and approach to personality assessment influence results, and indications of publication bias were found.

CONCLUSIONS

Neuroticism is the personality trait most widely studied in relation to PPD. Our meta-analysis found this trait is strongly related with PPD. Moreover, vulnerable personality style and trait anxiety are also associated with PPD. Screening for these traits might help identify women at risk, improving prevention, early detection, and possibly treatment.

Biological, Psychological, and Social Determinants of Depression: A Review of Recent Literature

Depression is one of the leading causes of disability, and, if left unmanaged, it can increase the risk for suicide. The evidence base on the determinants of depression is fragmented, which makes the interpretation of the results across studies difficult. The objective of this study is to conduct a thorough synthesis of the literature assessing the biological, psychological, and social determinants of depression in order to piece together the puzzle of the key factors that are related to this condition. Titles and abstracts published between 2017 and 2020 were identified in PubMed, as well as Medline, Scopus, and PsycInfo. Key words relating to biological, social, and psychological determinants as well as depression were applied to the databases, and the screening and data charting of the documents took place. We included 470 documents in this literature review. The findings showed that there are a plethora of risk and protective factors (relating to biological, psychological, and social determinants) that are related to depression; these determinants are interlinked and influence depression outcomes through a web of causation. In this paper, we describe and present the vast, fragmented, and complex literature related to this topic. This review may be used to guide practice, public health efforts, policy, and research related to mental health and, specifically, depression.

Maternal Distress and Offspring Neurodevelopment: Challenges and Opportunities for Pre-clinical Research Models

Pre-natal exposure to acute maternal trauma or chronic maternal distress can confer increased risk for psychiatric disorders in later life. Acute maternal trauma is the result of unforeseen environmental or personal catastrophes, while chronic maternal distress is associated with anxiety or depression. Animal studies investigating the effects of pre-natal stress have largely used brief stress exposures during pregnancy to identify critical periods of fetal vulnerability, a paradigm which holds face validity to acute maternal trauma in humans. While understanding these effects is undoubtably important, the literature suggests maternal stress in humans is typically chronic and persistent from pre-conception through gestation. In this review, we provide evidence to this effect and suggest a realignment of current animal models to recapitulate this chronicity. We also consider candidate mediators, moderators and mechanisms of maternal distress, and suggest a wider breadth of research is needed, along with the incorporation of advanced -omics technologies, in order to understand the neurodevelopmental etiology of psychiatric risk.

Preconception origins of perinatal maternal mental health

Perinatal maternal symptoms of depression and anxiety compromise psychosocial function and influence developmental outcomes in the offspring. The onset of symptoms remains unclear with findings that suggest a preconceptual origin. We addressed this issue with a prospective analysis of anxiety and depressive symptom profiles from preconception through to parturition. Women were recruited into a preconception study to assess (a) variation in symptom levels of depression and anxiety from pre- to post-conception and (b) if the symptom network profiles of depression and anxiety change from pre-conception to post-conception. A within-subject intraclass correlation analyses revealed that symptoms of depression or anxiety in the preconception phase strongly predicted those across pregnancy and into the early postnatal period. The symptom network analysis revealed that the symptom profiles remained largely unchanged from preconception into the second trimester. Our findings suggest that for a significant portion of women, maternal mental health remains stable from preconception into pregnancy. This finding highlights the need for early intervention studies on women's mental health to be targeted during the preconception period and to be extended across the population.

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.
