     According to a new study by Israel researchers from University of Haifa, posting blogs to express

feelings and emotions is therapeutic for children aged 13-17. Psychology professors Meyran

Boniel-Nissim and Azy Barak have found that a teenager writing a publicly-viewed blog on the Internet

is more effective for relieving stress rather than keeping a private diary. The study, published in the

journal Psychological Services, supports that expressing oneself through writing can be therapeutic.

     To conduct the research, Boniel-Nissim and Barak randomly selected Israeli high school students

who displayed a certain degree of stress. The teenagers were then divided into six groups. Two groups

were asked to post blogs twice a week about their social difficulties, but only one of them was asked

to open the blogs for comments. The next set of groups were also asked to blog twice a week to post

about whatever was going on in their mind, again with one group allowing comments. The two control

groups were asked to keep an old-fashioned private diary.

     The researchers then collected the blog posts and diaries to discuss the adolescents' emotional and

social position. From the research, they saw that the greatest improvement in mood was with the

bloggers who wrote about their personal troubles and allowed people to interact with their posts. The

research also noted that the comments were mostly positive and constructive. Boniel-Nissim and Barak

said that the commentators' interactions helped the bloggers while they were distressed. The conclusive

research noted that expressing yourself on the Internet not only let others know what was personally

going on with you, but also helped you figure out some things about yourself too.
