Video game addiction, also known as gaming disorder or internet gaming disorder, is generally defined as the problematic, compulsive use of video games that results in significant impairment to an individual's ability to function in various life domains over a prolonged period of time.

While gaming can be a healthy hobby for many, some people game so much that it interferes with other parts of their life.

There are 9 criteria for characterizing Internet Gaming Disorder:

Pre-occupation. Do you spend a lot of time thinking about games even when you are not playing, or planning when you can play next?

Withdrawal. Do you feel restless, irritable, moody, angry, anxious or sad when attempting to cut down or stop gaming, or when you are unable to play?

Tolerance. Do you feel the need to play for increasing amounts of time, play more exciting games, or use more powerful equipment to get the same amount of excitement you used to get?

Reduce/stop. Do you feel that you should play less, but are unable to cut back on the amount of time you spend playing games?

Give up other activities. Do you lose interest in or reduce participation in other recreational activities due to gaming?

Continue despite problems. Do you continue to play games even though you are aware of negative consequences, such as not getting enough sleep, being late to school/work, spending too much money, having arguments with others, or neglecting important duties?

Deceive/cover up. Do you lie to family, friends or others about how much you game, or try to keep your family or friends from knowing how much you game?

Escape adverse moods. Do you game to escape from or forget about personal problems, or to relieve uncomfortable feelings such as guilt, anxiety, helplessness or depression?

Risk/lose relationships/opportunities. Do you risk or lose significant relationships, or job, educational or career opportunities because of gaming?
