ULifeline is one way that technology is helping students explore their own well-being. This site reports over 10,000 visitors per month, and is customized to help provide resources for over 1,000 campuses. There are many self-screening quizzes that help students identify help for themselves or a friend. The site has many good articles about how to recognize problems and support peers.
Many college students are affected by anxiety and depression, but both of these problems are well-researched and improve with talk therapy and/or medication. Since stigma contributes to help-seeking behavior of college students, especially in certain groups, the internet could play a role in normalizing the experiences of help seekers and encourage cognitive awareness about mental health. More research should be done about how well sites that provide mental health information convert self-assessment to actual community-based help for the many college students who report symptoms.
Facebook is one online place where many college students spend time. It appears support from Facebook friends may play a role in increasing social capital, well-being, and combating stigma if friends are supportive to online disclosures. However, if you share your life on Facebook check your privacy settings: researchers may try to clinically diagnose your status updates without you ever knowing about it!
