在线社交网站（sns）已经成为青少年之间流行的交流方式。然而，人们对社交网络活动对健康行为的影响知之甚少。作者调查了朋友之间使用社交网络的情况，以及社交网络活动与面对面同伴影响和青少年危险行为之间的关系程度。纵向自我中心友谊网络数据以及青少年社交媒体使用和风险行为收集了来自南加州五所高中的1563名十年级学生的数据。使用固定效应模型计算和评估在线和离线同伴影响的度量。青少年使用社交网络的频率和使用同一社交网络的最亲密朋友的数量与风险行为没有显著相关。然而，接触朋友网上聚会或饮酒的照片与吸烟（β=.07, p<.001）和饮酒（β=.08, p<.05）显著相关。有酒友的青少年饮酒的风险更高，而没有酒友的青少年更容易受到接触危险网络图片的影响（β=−）。10、p < 10)。Myspace和Facebook在人口统计学上具有不同的用户特征，对风险行为有不同的影响。网络风险内容暴露对青少年的风险行为有直接影响，并与青少年朋友的风险行为有显著的交互作用。这些结果提供了证据，表明朋友的网络行为应该被视为同伴影响的一个可行来源，并且应该加大努力，教育青少年了解危险的网络展示的负面影响。
Online social networking sites (SNSs) have become a popular mode of communication between adolescents. However, little is known about the effects of social online activity on health behaviors. The authors examine the use of SNSs between friends and the degree to which SNS activities relate to face-to-face peer influences and adolescent risk behaviors. Longitudinal egocentric friendship network data along with adolescent social media use and risk behaviors were collected from 1,563 tenth grade students across five Southern California high schools. Measures of online and offline peer influences were computed and assessed using fixed effects models. The frequency of adolescent SNS use and the number of their closest friends on the same SNS were not significantly associated with risk behaviors. However, exposure to friends’ online pictures of partying or drinking was significantly associated with both smoking (β=.07, p<.001) and alcohol use (β=.08, p<.05). While adolescents with drinking friends had higher risk levels for drinking, adolescents without drinking friends were more likely to be affected by increasing exposure to risky online pictures (β=−.10, p<.10). Myspace and Facebook had demographically distinct user characteristics and had differential effects on risk behaviors. Exposure to risky online content had a direct impact on adolescents’ risk behaviors and significantly interacted with risk behaviors of their friends. These results provide evidence that friends’ online behaviors should be considered a viable source of peer influence and that increased efforts should focus on educating adolescents on the negative effects of risky online displays.
