This study investigated the temperament and character pattern and implicit or explicit association for the risk internet gaming disorder in young adults.


(1) 500 male middle school students were surveyed for psychological factors and compared these in at-risk internet gaming group with low risk group. (2) Using implicit association test and internet game expectancy scale, cognitive aspect was assessed for the relationships between explicit internet game expectancy, implicit internet game expectancy, and the level of internet game addiction.


At risk internet gaming group was associated with increased odds of high novelty seeking, harm avoidance, self-transcendence and low persistence factors. The explicit positive internet game expectancy and the levels of game addiction, and the implicit positive internet game expectancy and internet game behaviors had a significant positive relationship in young adults.


Internet gaming disorder has similar patterns of other substance user’s temperament and character. The result of study for cognitive aspect suggested that low levels of the explicit negative expectancy about the outcome of internet game use or higher levels of the implicit positive expectancy tend to engage in more internet game behavior and high levels of the explicit positive internet expectancy may be more vulnerable to internet game addicts.
