I would personally appreciate having the original source to look at. I am wondering if an effect size was calculated and if so, what that was. Additionally, how do the percentages break down in terms of different self-injurious behaviors? For example, how many burnt or hit themselves versus how many actually cut?
Everyone, IMHO, should be mindful that the sample used was taken only from China, which therefore invalidates its generalizability to the U.S.A.
And once again, the Internet allows the "bigger problems of society/world" to stare us right in the face- teens need to be guided and parented, and talked to, in order to explore their feelings and thoughts and see what is happening and wrong- and it would be a great idea, IMHO, to take this information and apply it to society and say "hey, our kids need help; and although parents aren't always 100% the problem, neither is the Internet. Both play a role in exacerbating the problem, so let's work on the problem (which is, OUR teens need help, e.g., psychoeducation, therapy, parenting!)."
