 The study tested the mediation effects of maladaptive cognitions related to internet gaming, MCIG, between interpersonal factors, impulsivity and self-control, an internet gaming disorder, IGD, and between interpersonal factors parental influences and peer influences, and IGD among adolescents in China. The results showed that MCIG partially mediated the associations between the studied factors and IGD, with effect sizes of 30.0% to 37.8%. Modifications of the three types of MCIG can potentially reduce the harmful impacts of impulsivity and interpersonal influences on IGD, and enhance the protective effect of self-control against IGD.
