Social Networking Sites (SNSs) have grown substantially, posing new hazards to teenagers. This study aimed to determine general patterns of Internet usage among Irish teenagers aged 11-16 years, and to identify potential hazards, including; bullying, inappropriate contact, overuse, addiction and invasion of users' privacy. A cross-sectional study design was employed to survey students at three Irish secondary schools, with a sample of 474 completing a questionnaire. 202 (44%) (n = 460) accessed the Internet using a shared home computer. Two hours or less were spent online daily by 285(62%), of whom 450 (98%) were unsupervised. 306 (72%) (n = 425) reported frequent usage of SNSs, 403 (95%) of whom were Facebook users. 42 (10%) males and 51 (12%) females experienced bullying online, while 114 (27%) reported inappropriate contact from others. Concerning overuse and the risk of addiction, 140 (33%) felt they accessed SNSs too often. These patterns among Irish teenagers suggest that SNS usage poses significant dangers, which are going largely unaddressed.
社交网站（SNSs）已大幅增长，给青少年带来了新的危害。本研究旨在确定11至16岁爱尔兰青少年的互联网使用总体模式，并识别潜在危害，包括欺凌、不当接触、过度使用、成瘾和侵犯用户隐私。采用横断面研究设计对爱尔兰三所中学的学生进行调查，474名学生完成了问卷调查。202名（44%）（n = 460）使用家里的共享电脑上网。285名（62%）每天上网时间在两小时或两小时以内，其中450名（98%）无人监管。306名（72%）（n = 425）报告经常使用社交网站，其中403名（95%）是脸书用户。42名（10%）男性和51名（12%）女性遭受过网络欺凌，而114名（27%）报告受到过他人的不当接触。关于过度使用和成瘾风险，140名（33%）觉得自己使用社交网站过于频繁。爱尔兰青少年中的这些模式表明，使用社交网站构成了重大危险，而这些危险在很大程度上未得到解决。
