There are quite a few papers. The good news about a scoping review is that essentially they've done your homework for you. They've looked at all the papers that fit within a particular framework, and they've included those in the scoping review. They've looked specifically at things like cost-effectiveness and whether it's changing attitudes and/or behaviours. We know there's a disconnect between attitudinal shifts and actual behavioural shifts.
It's a brilliant paper, because they've looked at the evidence globally over a 10-year period. It was published in 2015. It's an excellent paper. I'd be happy to give you the reference to that paper.
