In reply to iksander:
Ah, but that's another issue entirely. That's saying that exposure to western media, promarily western TV, can lead to young girs having unrealistic expectations of their body and hence issues with low self esteem, poor body image and eating disorders. This I would agree with.
Specifically:
"By comparing rates of eating disorders, a condition highly subject to social influences, among the girls, the team determined that those exposed to television were 60% more likely to display abnormal eating habits than those without such exposure.".
The article goes on to say that in an environment where the children have no direct exposure to western media, then second hand exposure through social networks may have an analogous effect. OK, it's a bit of a leap, but I'll accept it.
However, unless your daughter is living in an unconnected part of the world with no TV and their only exposure to western media is via social networks, then that article is utterly irrelevent.
For what its worth, self-harm and associated fun and games are more to do with taking control of your life from others, or so I've been told by suffers and ex-sufferers. I.e. "Daddy controls everything I do but he cannot force me to eat". Basically retreating from a world where things are inflicted on you to a world where *you* control what occurs, whether it be self-harm or weight control.
There's lots of other stuff, especially re- self harm (razors, etc) which involves causing yourself pain to demonstrate to yourself that you can still feel emotion and/or to block out emotion, but there's a common theme.
