A prospective, 1-site, parallel group, RCT (1:1 ratio) in which outcome assessors and data analysts will be blinded to maternal treatment will be used to compare online PHN-delivered group CBT for PPD to postnatal care as usual.~The primary objective of this study is to determine if online group CBT for PPD delivered by public health nurses is superior to postnatal care as usual in: a) acutely treating PPD, b) reducing relapse and recurrence, c) improving common comorbidities and complications of PPD including anxiety and the mother-infant relationship, and d) to determine if this treatment is cost-effective.~Women in the treatment group will participate in a 9-week group CBT intervention for PPD delivered via Zoom by two public health nurses. It consists of 9 weekly 2-hour sessions where core CBT skills are learned and practiced, and a new psychoeducational topic is introduced and discussed by women each week.
