MASSDEVICE ON CALL — Study: YouTube self-mutilation videos pose risk for youth. Researchers looked at 100 videos (selected by view number and other scientific parameters) and found that they have been viewed more than 2 million times, and "favorite’d" more than 12,000 times, on aggregate. About 14 to 24 per cent of youth and young adults injure themselves as a way of dealing with stress, but the presence of the videos could serve to normalize self-injury behavior, wrote the researchers in the journal Pediatrics. The scientists recommended that search engines provide people who search for self-mutilation videos resources such as websites and phone numbers for crisis lines.
