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.

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.
