A Blog as Therapy for Teenagers

  In the days before the instantly typed “OMG Where R U? ” the first words many teenagers wrote during their worried moments were“Dear Diary.”After several paragraphs of writing adolescent anxiety onto paper, the diarist often felt better.Research has long backed the thera-peutic(治疗的)value of diary-keeping for teenage girls and boys.But according to a new study, when teenagers detail their troubles onto a blog, the therapeutic value is even greater.

  To track teenagers’experiences with blogging, the researchers randomly surveyed high school students in Israel and selected 162 of them(124 girls and 38 boys)who exhibited some level of social anxiety or stress.The teenagers, who averaged 15 years old.said they had difficulty making new friends or relating to their existing friends.

  The teenagers were averagely divided into six groups.The first two groups were asked to blog about their social difficulties, with one group asked to open their posts to comments.The second two groups were asked to blog.about whatever struck their adolescent fancy;again.with one group allowing comments.All four groups were told to write in their blogs at least twice a week.As a control, two more groups were told to keep either an old-fashioned print diary or to do nothing at all.

  All of their blog entries were then gone Over by four psychologists to determine the authors' relative social and emotional state.In all the groups, the greatest improvement in mood occurred among those bloggers who wrote about their problems and allowed commenters to respond.Interestingly, the commenters on the blogs were almost supportive.

  “The only kind of surprise we had Was that almost all comments made by readers were very positive and constructive in trying to offer support for suffering bloggers,”Dr.Barak wrote in an e-mail.The findings may hold in the real virtual world as well.“I definitely write posts in which I talk about trouble, and it helps me to relax,”said Royar Loflin, a 17-year-old blogger from Norfolk, Va.
