dc.description.abstractBackground: Postpartum depression (PPD) affects 1 in 5 mothers and birthing parents. Unfortunately, many personal, practical, and systemic treatment barriers hinder those with PPD to receive their preferred treatment (psychotherapy). This study aimed to assess the effectiveness of Online Peer-Delivered 1-Day Cognitive Behavioural Therapy (CBT)-Based Workshops at treating PPD and its common comorbidities and complications. Methods: Participants were randomly allocated (1:1) to receive the 1-day workshop plus treatment as usual (TAU; experimental group) or TAU and placed on a waitlist to complete the workshop 12 weeks later (control group). Participants were eligible to participate if they were >18 years old, had an infant <12 months of age, and an Edinburgh Postnatal Depression Scale (EPDS) score >10. The workshop was a 1-day synchronous online, group CBT-based intervention delivered by two trained individuals who had recovered from PPD (i.e., peers). The primary outcome was change in PPD, assessed by the EPDS. Secondary outcomes included anxiety, mother-infant bonding, parenting stress, infant temperament, social support, and partner relationship discord. Results: 202 participants were randomized to the experimental group and 203 to the control group. The intervention led to significant reductions in EPDS scores from 15.95 pre-treatment to 11.37 post-treatment (d=0.92, p<0.01) and was associated with higher odds of exhibiting a clinically significant decrease in EPDS scores (OR=2.03, 95%CI: 1.26-3.29, NNT= 5.77, 95%CI: 3.46-17.24). Statistically significant improvements were also seen in postpartum anxiety (d=0.76, p<0.01), infant-focused anxiety (d=0.48, p<0.001), parenting stress (d=0.42, p<0.001), and infant positive affectivity (d=-0.81, p<0.001). Conclusion: Peer-delivered 1-day CBT-based workshops have the potential to improve PPD and its accompanying comorbidities and complications. The peer-delivered, brief, group, and online aspects of these workshops make it an ideal candidate for a low-intensity evidence-based treatment for PPD. This intervention is safe, engaging, and scalable, and has the potential to increase PPD treatment access.en_US

dc.description.layabstractPostpartum depression (PPD) affects up to 1 in 5 mothers and birthing parents and has short and long-term impacts on them and their infants. Due to various treatment barriers including stigma, costs, and long waitlists, only 1 in 10 of those with PPD receive treatment. This thesis aimed to investigate the effectiveness of an online peer-delivered 1- day cognitive behavioural therapy (CBT)-based intervention in treating PPD and its common comorbidities and complications. The results suggest that this brief intervention can lead to improvements in PPD, anxiety, mother-infant bonding, parenting stress, and infant temperament. Brief interventions delivered by recovered sufferers of PPD (i.e., peers) can be a novel intervention that is safe and engaging and can increase the number of mothers and birthing parents that seek and receive treatment. These workshops have the potential to effectively treat PPD and reduce treatment barriers.en_US
