Screening for postpartum depression and borderline personality disorder: Food for thought

Interventions for perinatal borderline personality disorder and complex trauma: a systematic review

Perinatal borderline personality disorder (BPD) and complex post-traumatic stress disorder (cPTSD) are associated with significant impairment to interpersonal functioning, and risk of intergenerational transmission of psychopathology. Evaluation of interventions, however, is scarce. To date, no systematic review has addressed interventions for perinatal BPD, cPTSD, and associated symptomatology. Given the modest evidence to support informed clinical guidelines, the objective of this systematic review is to synthesise the literature on interventions for perinatal BPD and cPTSD, and to generate future directions for research. A comprehensive literature search following PRISMA guidelines was conducted in PsycInfo, MEDLINE, Emcare, Scopus, and ProQuest Dissertations and Theses Global databases. Seven original studies were included, of which only two were randomised controlled trials, using less intensive comparison conditions. Results suggest an association between Dialectical Behavioural Therapy (DBT) group skills training, a multimodal therapeutic approach at a Mother-Baby Unit (MBU), and Child-Parent Psychotherapy with improved perinatal mental health outcomes and remission of symptoms. MBU admission and home-visiting programs were associated with healthy postpartum attachment relationships. Home-visiting programs and DBT group skills were additionally associated with improved maternal parenting capabilities. Conclusions to inform clinical guidelines are limited by a lack of credible comparison conditions, and low quantity and quality of evidence. The feasibility of implementing intensive interventions in real-world settings is dubious. Hence, it is suggested that future research considers utilising antenatal screening to identify at-risk mothers, and the implementation of early intervention, using robust designs that can inform robust conclusions.

The prevalence of borderline personality features and borderline personality disorder during the perinatal period: a systematic review and meta-analysis

Borderline personality disorder (BPD) is a psychiatric disorder marked by severe affective instability and poor interpersonal functioning. Existing literature has highlighted that individuals with BPD are at greater risk for a wide range of adverse physiological and psychosocial outcomes in the perinatal period compared to perinatal individuals without BPD. However, to date, no systematic review has addressed the prevalence of BPD and borderline personality features (BPF) in pregnant and postpartum individuals. A systematic review and meta-analysis was conducted by searching three databases (PubMed, PsycINFO, and Embase) on April 6th, 2021. Research articles and conference abstracts that evaluated BPF or BPD in pregnant, postpartum, or mixed perinatal populations were included. Sixteen publications were included in the systematic review (n = 14 research articles, n = 2 conference abstracts), seven of which were included in the meta-analysis. Among non-clinical samples, prevalence rates of BPF during pregnancy ranged from 6.9 to 26.7%, while rates of BPD across the perinatal period ranged from 0.7 to 1.7%. Among clinical samples, rates of BPF and BPD across the perinatal period spanned 9.7-34% and 2.0-35.2%, respectively. Results from the meta-analysis revealed that the pooled prevalence rate of BPD in clinical samples during the perinatal period is 14.0% (95% CI [7.0, 22.0]). Among clinical perinatal samples, there is a high prevalence of borderline personality pathology. This review highlights the need for appropriate validated screening methods to identify and treat BPD in the perinatal population.

Comorbid borderline personality disorders in women with post-partum depression admitted to mother-baby units

Borderline personality disorder (BPD) is associated with perinatal depression and parenting difficulties. However, little is known about the characteristics and specific effects of BPD in women with postpartum depression. This study aimed to explore 1) the sociodemographic, mental health characteristics, and motherhood difficulties in women with a major depressive postpartum episode (MDPE) and a comorbid diagnosis of BPD, compared to those with other personality disorders (other PD) or no PD and 2) whether BPD itself may be an independent risk factor for infant neglect in women with a MDPE. 412 women admitted to a Mother and Baby Unit (2001-2010) with a MDPE were involved in this study. Our study showed that women with MDPE-BPD (n = 64) more frequently reported a history of childhood maltreatment, single status, low social support, a history of depression, smoking during pregnancy and suicide attempt during the perinatal period compared to women with other PDs (n = 88) or no PD (n = 260). Women with comorbid BPD had a greater length of stay. Regarding infant care, neglect, abuse, and separation at discharge were more frequent in women with comorbid BPD. Logistic regression was performed to specifically examine whether BPD in women with a MDPE was an independent risk factor for infant neglect during the postpartum period. Comorbid BPD was independently associated with infant neglect (OR = 2.21; CI95% [1.02-4.81]). Our results underline the importance of screening for BPD in women with perinatal depression. Further studies are needed to explore the links between MDPE, BPD, and infant development.

Prevalence and characteristics of women with borderline personality pathology referred to a perinatal consultation liaison service

OBJECTIVE

To examine the prevalence and characteristics of pregnant women with borderline personality pathology (defined as borderline personality disorder and borderline personality traits) referred to a perinatal consultation-liaison psychiatry service.

METHOD

Socio-demographic and clinical data, and diagnoses made according to Diagnostic and Statistical Manual of Mental Disorders (5th ed.) criteria were recorded for all women referred to and seen by the perinatal consultation-liaison psychiatry service over an 18-month period. Data were analysed using descriptive statistics and logistic regression analysis.

RESULTS

A total of 318 women were seen. The most common diagnoses found were depressive disorder (25.5%) and anxiety disorder (15.1%). Borderline personality disorder was found in 10.1% of women and almost one in five women had two or more borderline personality traits (19.5%). When compared to women with other diagnoses, women with borderline personality pathology had higher rates of unplanned pregnancy, being unpartnered, substance use during pregnancy and higher rates of child safety services involvement as a child or in a previous pregnancy. Over 40% of women with borderline personality pathology were referred to child safety services in the current pregnancy and a diagnosis of borderline personality pathology increased the risk of child safety services involvement by almost sixfold (odds ratio: 5.5; 95% confidence interval = [1.50, 20.17]).

CONCLUSION

The prevalence of borderline personality pathology in antenatal women identified at antenatal screening and the recognition that women with borderline personality pathology are 'high-risk' caregivers argue for borderline personality pathology to be recognised as a high priority for investment in service development.
