Don't parents need to give consent for adolescents to participate in research?

Normally, yes! However, there are also times when it’s okay to not involve parents. One reason is the fact that this study is online! It’s pretty much impossible to get parental approval when doing research over the internet. Also, it’s important to protect the privacy of our participants! In many cases, researchers who are doing studies like this one are allowed to do their research without parental consent.
