  1. Group differences for demographic and psychological variables were analyzed. Bonferroni correction was applied to the post hoc analyses, and the significance level was set at 0.0167. IGD (I) = Internet gaming disorder; AUD (A) = alcohol use disorder; HC (H) = healthy control; IQ = intelligence quotient; IAT = Young’s Internet Addiction Test; AUDIT = Alcohol Use Disorder Identification Test; BDI-II = Beck Depression Inventory-II; BAI = Beck Anxiety Inventory; and BIS-11 = Barratt Impulsivity Scale-11.
