I think the PND assessment tool is good but would also want to do an exploratory and open-ended interview re supports the woman has and is likely to access, from her partner, own extended family, in-law relationships, MCHN, groups such as new mother's group and local playgroups. The woman should be able to direct the session around what she feels is important and is impacting her. I think the better the awareness a mum has of the importance of supportive buffers like mothers' groups and the more inclined she is to utilise them, the less likely she is to spiral into depression.
