尽管对问题互联网使用(PIU)的流行率及其相关性进行了许多研究，但我们对其病因成分知之甚少。我们的主要目的是利用经典的双胞胎设计，找出PIU在多大程度上受到遗传和环境因素的影响。共有237对年龄在10-25岁的土耳其双胞胎参与了这项研究。使用杰伊汉、杰翰和古尔坎开发的“有问题的互联网使用量表”(PIUS)对Pill进行衡量。对于男性双胞胎，同卵双胞胎(MZ)的双胞胎相关大于同卵双生(DZ)双胞胎的相关，表明遗传因素影响PIUS得分。然而，对于女性双胞胎，PIUS的MZ相关小于DZ相关，表明遗传因素在女性双胞胎中不起作用。通过模型拟合分析，探讨了遗传因素和环境因素的影响。结果表明，在“社会舒适度/效益”和“上网带来的负面影响”两个子维度上，ADE模型是最适合的模型，而对于“过度使用”和“PIUS-Total”两个子维度，最适合的模型是ACE模型。这项研究的关键结果是，遗传效应和非共享环境效应对男性双胞胎的总体PIU具有同等的影响。(C)2014爱思唯尔有限公司。保留所有权利。
Despite many studies on the prevalence and correlates of problematic Internet use (PIU), we know little about its etiological components. Our main aim is to find out to what extent PIU is influenced by genetic and environmental factors using the classic twin design. A total of 237 Turkish twin-pairs aged 10-25 participated in the study. Pill was measured using the 'Problematic Internet Use Scale' (PIUS) developed by Ceyhan, Ceyhan and Gurcan. For male twin-pairs, the monozygotic (MZ) twin correlations were larger than the dizygotic (DZ) twin correlations, indicating that genetic factors influenced scores on the PIUS. However, for female twin-pairs, the MZ correlations were smaller than the DZ correlations for the PIUS, showing that genetic factors did not play a role in female twin-pairs. The influence of both genetic and environmental factors was explored with model-fitting analysis. Results showed that both for the "social comfort/benefit" and "negative consequences associated with the Internet use" sub-dimensions, the best-fitting models were the ADE models whereas both for the "excessive use" sub-dimension and "PIUS-Total", the best-fittings models were the ACE models. The key result of this study is that the genetic and non-shared environmental effects are equally influential on the overall PIU in male twin-pairs. (C) 2014 Elsevier Ltd. All rights reserved.
