To explore the Internet use and interpersonal interactions of youth reporting deliberate self-harm as defined by any non-fatal act, regardless of intention.
The Second Youth Internet Safety Survey is a nationally representative telephone survey of 1500 Internet users (ages 10-17) in the United States, conducted March to June 2005.
Youth reporting deliberate self-harm in the past 6 months (3%) were significantly more likely than other youth to have a sexual screen name or to talk with people known only online about sex (35% versus 5%) and to use chat rooms (57% versus 29%). All youth were equally likely to talk online with people known in person, yet youth engaging in deliberate self-harm were significantly more likely also to have a close relationship with someone met online (38% versus 10%). Three quarters (76%) of youth reporting self-harm used instant messaging.
Findings suggest that youth who engage in self-harm may be more likely to engage in online behaviors that have the potential to place them in risky situations. Programs aimed at preventing deliberate self-harm should consider adding chat room and instant messaging to their telephone hotline capabilities.
探讨有故意自我伤害行为（定义为任何非致命行为，无论其意图如何）的青少年的互联网使用情况及人际互动。
第二次青少年互联网安全调查是2005年3月至6月在美国对1500名互联网用户（年龄在10 - 17岁）进行的具有全国代表性的电话调查。
在过去6个月中有故意自我伤害行为的青少年（3%）比其他青少年更有可能拥有带有性暗示的网名，或与仅在网上认识的人谈论性话题（35%对5%），以及使用聊天室（57%对29%）。所有青少年与现实中认识的人在网上聊天的可能性相同，但有故意自我伤害行为的青少年与在网上结识的人建立亲密关系的可能性也显著更高（38%对10%）。报告有自我伤害行为的青少年中有四分之三（76%）使用即时通讯工具。
研究结果表明，有自我伤害行为的青少年可能更倾向于参与那些有可能使他们处于危险境地的网络行为。旨在预防故意自我伤害行为的项目应考虑在其电话热线服务中增加聊天室和即时通讯功能。
