If you have a friend who is showing signs of video game addiction:

• Share your concerns directly and calmly with your friend.
  
• Provide specific examples of negative consequences like neglected obligations, too much time or money, etc.
  
• Have your conversation about concerns at a time that is conducive to communication. Don't try to have the discussion while he/she is playing or has just finished playing. If necessary, make an appointment to have the conversation.
  
• Don't argue or threaten. State your concerns clearly and suggest specific changes.
  
• If the addictive behavior continues, enlist the help of other friends or relatives to join you as concerned persons in the discussions.
  
• In cases where the addict denies the problem or is unsuccessful in keeping promises, consider consulting a professional who conducts addiction interventions. An intervention is a structured meeting led by a professional. It typically includes a group of concerned persons who confront the addict in a caring way making clear both the negative consequences of the addiction and a clear plan of action, perhaps seeking further help.
  
• If none of these steps have been successful, you may need to think through what consequences you are prepared to enact. State those clearly to the addict and follow through on them.
