I recently purchased a very informative e-book called "How to Help Children Addicted to Video Games - A Guide for Parents [by Dr. Brent Conrad, Clinical Psychologist, www.TechAddiction.ca}
It is a practical manual that I do not believe is available at any other source (e.g. Amazon). I founmd it to be very well organized with a balanced content addressing:
PART I: Information and Education: (basic information about what video game addiction is (and is not)
PART II: Assess your Situation: (how to assess whether or not you (and your child) have a serious problem.
PART III: Prepare for Action:(understanding why it is important to fight this addiction)
PART IV: Strategies, Tips, and Thoughts for Moderation: (practical tips on what you can do to prevent and/or alleviate the overuse of electronics.
SUMMARY: Although you will find all sorts of information on the internet about this issue; including scary statistics about prevelance and "common sense" tips for intervention, I have yet to find a more practical and informative resource for parents who have a serious problem with a child (or children) addicted to video games and are serious about solving it.
