This study aimed to identify risk factors involved in Internet addiction. A total of 216 college students (132 males and 84 females) were given the following: (a) the diagnostic interview for Internet addiction, (b) the Iowa gambling test for decision-making deficits, (c) the Balloon Analog Risk Test (BART) to assess risk-taking tendencies, and (d) the Tridimensional Personality Questionnaire (TPQ) for personality characteristics. The results revealed the following: (a) 49% of males and 17% of females were addicted, (b) the addicted students tended to select more advantageous cards in the last 40 cards of the Iowa test, indicating better decision making, (c) no difference was found for the BART, indicating that addicted subjects were not more likely to engage in risk-taking behaviors and (d) TPQ scores showed lower reward dependence (RD) and higher novelty seeking (NS) for the addicts. Their higher performance on the Iowa gambling test differentiates the Internet addiction group from the substance use and pathologic gambling groups that have been shown to be deficient in decision making on the Iowa test. Thus, students that fit these characteristics should be closely monitored to prevent Internet addiction.
本研究旨在确定网络成瘾的相关风险因素。共有 216 名大学生（132 名男性和 84 名女性）接受了以下测试：（a）网络成瘾诊断访谈，（b）爱荷华赌博测试以评估决策缺陷，（c）气球模拟风险测试（BART）评估冒险倾向，（d）三维人格问卷（TPQ）评估人格特征。结果显示：（a）49%的男性和 17%的女性成瘾，（b）成瘾学生在爱荷华测试的最后 40 张卡片中倾向于选择更有利的卡片，表明决策能力更好，（c）BART 没有差异，表明成瘾者不太可能从事冒险行为，（d）TPQ 分数显示成瘾者的奖励依赖（RD）较低，新奇寻求（NS）较高。他们在爱荷华赌博测试中的较高表现将网络成瘾组与已经显示在爱荷华测试中决策能力缺陷的物质使用和病理性赌博组区分开来。因此，应密切监测具有这些特征的学生，以预防网络成瘾。
