To be diagnosed as having FAD, a person must meet certain criteria. At least 2 or 3 of the following 6 criteria must be present at any time during a 6-8 months period.

1. Intolerance. Referring to the need for increasing amounts of time on Facebook to achieve satisfaction and/or significantly diminished effect with continued use of the same amount of time. They often have multiple FB windows opened at any one time.

2. After reduction of FB use or cessation, it causes distress or impairs social, personal or occupational functioning such as wondering why your Vista is so fast and improved etc. These include anxiety; obsessive thinking about what is written on your wall on FB etc.

3. Important social or recreational activities are greatly reduced and or migrated to FB. Instead of sending an email, you post a message on your friend's page about canceling a lunch appointment. You now stop answering your phone call from your mom and insist that she should contact you thru FB chat.

4. This is getting serious if you start kissing your partner's home page, or taking a virtual walk through a park is your idea of a date.

5. Your bookmark takes 20 min just to scroll from top to bottom or 8 of 10 people in your friend's list you have no idea of who they are.

6. When you meet people, you start introducing yourself by following "see you in FB" or your dog has its own FB profile. Basically, you invite anyone you've met and any notifications, messages and invites reward you with an unpredictable high feeling.

So, how many many of the above do you see yourself in?
