I've done a fair bit of work around the evidence for this. I think this echos back to the need to move toward a family-centred model of service delivery. As [Technical difficulty—editor] when they come in for mental health services, there is a primary referral. That's the name on the referral. That's what gets all of the remuneration going. This is how people get paid to deliver the service. But it happens...in the context that there is a secondary client, and that is whatever your social support is—typically your family, as a child. This is how it functions, because people exist in these systems.
Social support is one of the biggest predictors of people doing well in the context of living with mental health issues, so the idea that we would provide a service to someone who has something like PTSD, without supporting the family to support the person who has PTSD, is counterintuitive.
