The present study has identified successfully two distinct
groups of gamers: one group of addicted heavy online gamers and another group of heavy but non-addicted
online gamers, thus confirming our main hypothesis. The
addicted heavy online gamers differed only slightly from
the non-addicted heavy gamers (and various other
groups) in terms of psychosocial health. However, some
of these addicted gamers showed persistence over time,
i.e. half the addicted online gamers were still addicted 1
year later.
