Personally, I don’t think the researches view is correct. It’s good that they want to help young adults/kids with depression, but when conducting a research project about it on a child/young adult the parents should be included so they can verify that it is okay for their child to participate. And yes, I think it does depend on the nature of the research because it could be a very bad research topic or it could be a helpful one. Either way I think if it is a child or teenager who is asked to participate in these their parents should be included in verifying that it is okay for them to participate.
Hopefully this helped! :)
