Internet addiction and mobile phone addiction are both forms of technology addiction, and thus would be expected to show similarities and differences. This study investigated the association between the Internet Addiction Test (IAT) and the Mobile Phone Dependence Questionnaire (MPDQ) as a test of concurrent validity. Participants were 1,072 students aged between 9 and 18 years old (63% male and 37% female) from three primary schools and three secondary schools in Hong Kong. Correlations showed that scores on the two measures were moderately correlated, providing further evidence of each measure's validity. Confirmatory factor analysis that the IAT's factor structure was similar in both younger and older samples, suggesting that it is developmentally appropriate for primary and secondary school students. Latent Class Analysis showed that 4 classes or 5 classes are appropriate for IAT's score classification. ROC analyses showed similar rates of participants with high scores on the IAT and on the MPDQ. The outcomes have implications for the prevention and treatment of Internet and mobile phone addiction. Future research can establish norms for different ages, genders and cultural groups.
网络成瘾和手机成瘾都是技术成瘾的形式，因此应该表现出相似和不同之处。本研究调查了网络成瘾测试（IAT）和手机依赖问卷（MPDQ）之间的关联，以检验其同时效度。参与者是来自香港三所小学和三所中学的 1072 名 9 至 18 岁的学生（63%为男性，37%为女性）。相关性分析表明，两种测量方法的得分中度相关，进一步证明了每种测量方法的有效性。验证性因子分析表明，IAT 的因子结构在年龄较小和较大的样本中相似，表明它适合小学生和中学生的发展。潜在类别分析表明，IAT 的分数分类适合分为 4 类或 5 类。ROC 分析表明，IAT 和 MPDQ 高分的参与者比例相似。研究结果对预防和治疗网络和手机成瘾具有启示意义。未来的研究可以为不同年龄、性别和文化群体建立规范。
