There's a recent scoping review by a colleague of mine from the University College London. Her name is Julia Bailey. She's put out a very comprehensive scoping review on the issue of Internet sexual health information. In that you'll find evidence-based.... They have looked at sexual health interventions across the U.K., and specifically have looked at which are considered effective in terms of the affective domain, in terms of knowledge, and translating that knowledge into behaviour. I think that's a good place to start.
Wales also has a really nice national sexual health promotion set of guidelines. I think those are, again, set at the national level and are meant to trickle down to how that happens within each of the provisioning areas that are responsible for sexual health education, including schools.
I think we need to look at Australia, the U.K., and other contexts where, I would argue—and I mean this with all due respect—they are much more progressive in tackling this at a much younger age than we are.
We let it go and hope for the best. We're finding, using the example of increased rates of STIs, that this information is not getting to kids. If it were, and it were getting to them in an effective way, we wouldn't see the levels of STIs we see in this country. We also wouldn't see the levels of sexual violence in this country.
