Internet addiction (IA) has been explored worldwide and involves some features that might harm social, psychological, and functional aspects. The vulnerability of adolescents might result in some addictive behaviors, and the Internet is one of them. The aim of this systematic review was to identify empirical studies that have been done to explore instruments that have been used to assess IA and to verify what variables and comorbidities are related to IA in adolescents, including executive functions, such as attention. To accomplish our aim, a systematic search was conducted in the following databases: PubMed, Web of Science, and PsycINFO. Some inclusion and exclusion criteria were used to select the studies and 44 in total were analyzed independently. The results showed that the most used instrument to assess IA is the Young's Internet Addiction Test. A few studies have been developed in the Western world, and most of them have analyzed attention bias in attention-deficit/hyperactivity disorder (ADHD) and non-ADHD groups. Furthermore, other variables have been widely explored in the studies, such as depression, sleeping patterns, body weight, aggressiveness, and other addictive substances.

青少年的互联网成瘾和注意力：系统评价

网络成瘾（IA）已在全球范围内进行了探索，其中涉及一些可能损害社会，心理和功能方面的功能。青少年的脆弱性可能导致某些成瘾行为，互联网就是其中之一。该系统评价的目的是确定进行的经验研究，以探索用于评估IA的手段，并验证哪些变量和合并症与青少年IA相关，包括执行功能，例如注意力。为了实现我们的目标，在以下数据库中进行了系统的搜索：PubMed，Web of Science和PsycINFO。使用一些纳入和排除标准来选择研究，并且独立分析了总共44项。结果表明，最常用的评估IA的工具是Young 的互联网成瘾测试。西方世界已经开展了一些研究，其中大多数研究分析了注意力缺陷/多动症（ADHD）和非ADHD组的注意力偏倚。此外，在研究中还广泛探索了其他变量，例如抑郁，睡眠方式，体重，攻击性和其他成瘾性物质。
