目的：确定在线干预是否能减少高危青少年在社交网站上涉及性和药物滥用的内容。
设计：随机对照干预试验。
地点：www.MySpace.com
参与者：自我描述为18 - 20岁、在MySpace上有公开个人资料且符合我们的高危标准的人（N = 190）。
干预措施：单一医生的电子邮件。
主要观察指标：在干预前和干预3个月后，对网络个人资料中涉及性和药物使用的内容以及安全设置进行评估。
结果：在190名受试者中，58.4%为男性。在基线水平时，54.2%的受试者在其社交网站个人资料中提及性，85.3%提及药物使用。在干预组中，涉及性的内容减少到0的个人资料比例为13.7%，而对照组为5.3%（P = 0.05）；涉及药物使用的内容减少到0的比例在干预组为26.0%，对照组为22%（P = 0.61）。随访时设置为“私密”的个人资料比例在干预组为10.5%，对照组为7.4%（P = 0.45）。在干预组中，进行了这3种保护措施中任何一种改变的个人资料比例为42.1%，对照组为29.5%（P = 0.07）。
结论：利用社交网站进行的简短电子邮件干预在减少高危青少年网络个人资料中的性相关内容方面显示出有希望的前景。进一步的研究应评估青少年如何看待不同的风险行为披露，以促进互联网的安全使用。
Objective: To determine whether an online intervention reduces references to sex and substance abuse on social networking Web sites among at-risk adolescents.Design: Randomized controlled intervention trial.Setting: www.MySpace.com.Participants: Self-described 18- to 20-year-olds with public MySpace profiles who met our criteria for being at risk (N=190).Intervention: Single physician e-mail.Main Outcome Measures: Web profiles were evaluated for references to sex and substance use and for security settings before and 3 months after the intervention.Results: Of 190 subjects, 58.4% were male. At baseline, 54.2% of subjects referenced sex and 85.3% referenced substance use on their social networking site profiles. The proportion of profiles in which references decreased to 0 was 13.7% in the intervention group vs 5.3% in the control group for sex (P=.05) and 26.0% vs 22% for substance use (P=.61). The proportion of profiles set to "private" at follow-up was 10.5% in the intervention group and 7.4% in the control group (P=.45). The proportion of profiles in which any of these 3 protective changes were made was 42.1% in the intervention group and 29.5% in the control group (P=.07).Conclusions: A brief e-mail intervention using social networking sites shows promise in reducing sexual references in the online profiles of at-risk adolescents. Further study should assess how adolescents view different risk behavior disclosures to promote safe use of the Internet.
