From what I have encountered from studying addiction in university is that all treatments of addiction starts with people realising they have a problem. For people to come to terms with this there is a need to have a talking strategy in place I.e. CBT and a coping mechanism also. There has been found to be links between internet addiction and impulse control disorders, of which CBT has had very positive. I have attached a paper from 2007 which talks about tests to identify the addiction and the treatment to go along with it.
