网络成瘾是一个越来越令人担忧的问题,然而,无论是驱动问题行为的机制和评估症状的金标准工具缺乏一个清晰的理解。本研究的目的是进行心理测量分析的最广泛使用的筛选工具,青年网络成瘾测试(IAT),使用美国大学生的样本。215(70%的响应率)本科大学生从美国两所大学招募完成IAT的在线版本。使用探索性因素分析,提取两个因素,“依赖使用”和“过度使用”,这两个因素共同解释了总方差的91%。在IAT的问题用户类别中得分的参与者在依赖使用量表上的项目平均高出0.8±1.5分,在过度使用量表上的项目平均高出1.4±1.5分。结果表明,网络成瘾症状可能聚集为两个独立的组成部分:依赖性和过度使用。此外,IAT似乎是一个有效的工具来评估美国大学生的网络成瘾。
Internet addiction is a growing concern; however, both a clear understanding of the mechanisms driving problematic behaviors and a gold standard instrument for assessing symptoms are lacking. The purpose of this study was to perform a psychometric analysis of the most widely used screening instrument, the Young Internet Addiction Test (IAT), using a sample of US college students. 215 (70% response rate) undergraduate college students were recruited from two US universities to complete an online version of the IAT. Using exploratory factor analysis, two factors were extracted, “dependent use” and “excessive use” which together explained 91% of the total variance. Participants who scored into the problematic user category of the IAT scored items on the dependent use scale an average of 0.8±1.5 points higher and items on the excessive use scale an average of 1.4±1.5 points higher than participants who scored in the average user category. Results suggest that Internet addiction symptoms may cluster into two separate components, dependent and excessive use. Further, the IAT appears to be a valid instrument for assessing Internet addiction in US college students.
