Online treatments delivered in groups have potential to be an effective means of support for those with PPD, as they can help expand social networks and reduce travel and childcare barriers. Public health nurses (PHNs) play a key role in PPD screening and are often the first point of contact for birthing parents in healthcare and community settings.

A group of lay peers and PHNs are trained to deliver the 9-week group CBT intervention and a peer is paired with a Public Health Nurse to deliver the 9-week CBT sessions. Peer-administered treatments, those delivered by people who have previously recovered, may be an effective alternative to traditional mental health services. They could also help women with PPD overcome many of the barriers they face when attempting to find help. Considering PHNs are perceived as the optimal non-specialist provider of PPD treatment and given the large number of recovered peers that exist to provide support for those with PPD, CBT groups co-led by PHNs and peers could offer a more engaging and accessible way to treat PPD while offering the promise of clinical and cost-effectiveness.
