Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants allocated to the intervention group will be sent a link via email or SMS to participate in an online psychoeducation program via Qualtrics within one week of completing screening questionnaires. Modelled on Mother Infant Dialectical Behaviour Therapy (MI-DBT; Sved Williams et al., 2018), the brief digital psychoeducation intervention will take approximately thirty minutes to complete, presented as written information. The psychoeducation will address how past trauma can lead to emotional dysregulation (Blankley et al., 2015; Pare-Miron et al., 2016), and list appropriate parenting practices such as infant soothing skills (Geerling et al., 2019; Sved Williams et al., 2018), strategies for emotional regulation, behaviour awareness (Eyden et al., 2016), mother-infant dyadic interaction, empathy, and sensitivity (Newman & Stevenson, 2005; Newman et al., 2007). Post completion, the intervention group will receive a brief 5-question multiple choice quiz to ensure that content was actively received. Participants will have the option of downloading the psychoeducation, and will be sent two email reminders of content to ensure memory retention, approximately one week and one month after.

Comparator / control treatment
Participants in the control group will be sent a link via email or SMS with newsletter content derived from the Centre of Perinatal Excellence, offering general information about parenting and mental health. Comparable to the intervention group, completion will take approximately thirty minutes to complete, occurring once only.

Efficacy
Statistical methods / analysis
To examine comparative outcomes on our primary outcome measure, we will use linear mixed modelling. It yields unbiased estimates of intervention effects under the assumption that data are missing at random (MAR; Han & Guo, 2014). An unstructured covariance matrix will be assumed. All analyses will be adjusted for baseline observations (i.e., the first assessment during pregnancy) to ensure that outcomes resulted from intervention-related influences and not measurement error or baseline score differences, and therefore significant between group results as well as significant interactions between time and group were both of interest. This will result in a 2 (group: intervention, informational control) x 2 (time: pre-intervention, post-intervention) repeated measures design, and a priori Bonferroni corrections will be used to examine comparisons between the groups. Between group Cohen’s d effect sizes will be calculated, where 0.2 = small; 0.5 = moderate, and 0.8 = large differences (Cohen, 1992). All models will also be examined for interactions with the following variables: SES (bottom and top 50th percentile), and high and low levels of depression.

Summary
Brief summary
The perinatal period, encompassing pregnancy and the first year postpartum, is a time of immense change where women are faced with new challenges, stress, and high emotions (Chlebowski, 2013; Newman et al., 2007). Previous coping strategies may prove inadequate when faced with sleep deprivation, a crying infant, physical pain, role transformation, and relationship stress (Geerling et al., 2019; Sved Williams & Apter, 2017; Wilson & Donachie, 2018). Women with personality vulnerability may become emotionally unstable (Sved Williams et al., 2018; Yelland et al., 2015), and existing symptoms of borderline personality disorder (BPD) may be exacerbated (Dunn et al., 2020). The National Health and Medical Research Council (2012) guidelines recommend that women with BPD who are pregnant, have infants or young children “should be provided with interventions designed to support parenting skills and attachment relationships”. As dysregulation (Apter at al., 2017) and neurobiological disturbances (Newman et al., 2011) can occur in infants of mothers with BPD by three months of age, early intervention is imperative. We will evaluate the impact of the provision of psychoeducation material in pregnant women with BPD/BPD traits compared to general information about parenting and mental health. It is hypothesised that emotional regulation, obstetric/birth outcomes, postnatal maternal behaviours will be less compromised for women who have completed psychoeducation compared to women who have completed general information about parenting and mental health.
