Abstract: | Objectives: To determine whether task-shifting the treatment of Postpartum depression (PPD) is effective in both treating mothers and mitigating the potential negative effects of PPD exposure on infant emotion regulation (ER). Methods: In Study 1, a randomized controlled trial (RCT) with a waitlist control group was used to examine whether a nine-week group Cognitive Behavioural Therapy (CBT) intervention delivered by peers can effectively treat PPD in mothers. Study 2 used data from this same RCT to determine if maternal PPD treatment with peer-delivered group CBT intervention would lead to adaptive change in markers of ER in their infants. Finally, Study 3 used data from a RCT with a treatment-as-usual control group to examine whether maternal treatment with a Public Health Nurse (PHN)-delivered group CBT intervention led to adaptive change in markers of infant ER. In both Studies 2 and 3, markers of infant ER included two neurophysiological measures and a maternal-report measure of infant temperament. Results: Study 1 found that peer-delivered group CBT led to significant improvements in symptoms of depression and anxiety in mothers and reductions in symptoms remained stable six months after treatment initiation. Study 2 found evidence of change in two neurophysiological measures of infant ER following maternal treatment with peer-delivered intervention, but not in the maternal-report measure of infant temperament. Finally, Study 3 found evidence of change in a single neurophysiological marker of infant ER following maternal treatment with the PHN-delivered intervention, but found no change following maternal treatment in a second neurophysiological marker and maternal-report measure of infant ER. Conclusions: The studies in this thesis highlight the potential of using task-shifting to fill a gap in the healthcare system’s treatment of PPD. This work suggests that interventions delivered by peers and PHNs may not only be effective in treating those with PPD, but may also benefit their infants by mitigating any PPD-related consequences on infant ER development. This thesis contributes to the evidence that suggests timely maternal treatment of PPD may disrupt the transmission of psychiatric risk from parent to infant. |
