Before we get stuck into the paper that we've just published in the Lancet Obstetrics, Gynaecology and Women's Health, could you set the scene a little and outline the original SUMMIT intervention, the rationale for undertaking the study, and an overview of the intervention itself.

So obviously we both have a passion for improving access to these effective talk therapies for perinatal depression and anxiety.

And so the premise of Summit is not does psychotherapy work, but really to ask who can deliver psychotherapy How can it be delivered? And how can we get it to many people without compromising quality? I would say those were three big questions.

And so it was this idea of redesigning how evidence-based talk therapies could be delivered rather than creating new ones.

And so the basic premise of SUMMIT, which stands for scaling up maternal mental health care by increasing access to treatment, that's a mouthful, so I'm just going to stick with SUMMIT.

is that we know we can treat perinatal depression.

Every clinical guideline globally suggests that psychotherapies, talk therapies are the first line treatment to address this extremely common problem.

So could you summarize these findings for us, please?

Then what happened between McGill and your current position then?

My then boyfriend, now husband, lived in Toronto.

So here I was, I just graduated from McGill.

My cohort was very ambitious.

They had plans to pursue postdocs.

Many of them had already opened up private practices.

I had no plans whatsoever.

One is what explains that growth? And then what else can we do to really ensure we continue with it?
