The "ABCDE" of video gaming control: Arguments, basic research, conceptual models, documented lessons, and evaluation.

This commentary responds to the review conducted by Király et al. (2018). The review enlightens and is useful in view of the limited studies on problematic use of video games and related control policies. It is argued that when considering regulation policies on video games, reference should be made to the arguments involved (A), basic research (B), conceptual models on problem video game use (C), documented lessons learning the broad field of addiction (D), and the need for rigorous evaluation (E). Besides "supply" reduction, it is vital to look at "demand" reduction in terms of how inner strengths may help to reduce the problematic use of video games.
