You will probably need to see a professional therapist if you’ve answered five or more “yes” to following questions (Young Diagnostic Questionnaire for Internet Addiction by Young, 1998 and Beard and Wolf, 2001).
- Do you feel absorbed in the Internet (remember previous online activity or the desired next online session)?
- Do you feel satisfied with Internet use if you increase your amount of online time?
- Have you failed to control, reduce, or quit Internet use repeatedly?
- Do you feel nervous, temperamental, depressed, or sensitive when trying to reduce or quit Internet use?
- Do you stay online longer than originally intended?
- Have you taken the risk of losing a significant relationship, job educational or career opportunity because of the Internet?
- Have you lied to your family members, therapist, or others to hide the truth of your involvement with the Internet?
- Do you use the Internet as a way of escaping from problems or of relieving an anxious mood (e.g. feelings of helplessness, guilty, anxiety, or depression)?
