This study focuses on how social networking site (SNS) users’ perceived risk is affected by perceptions of the duality of potentially harmful events (cyber-attacks and privacy breaches) on SNS and explores the potential threat sources that influence such perceptions. Further, it examines the effects of perceived risk on SNS members’ site use and the underlying mechanisms through which these effects are cast. The study finds that users’ perceived SNS risk affects site use behavior through attitude as an important mediator and users’ concern regarding cyber-attacks (security) casts a greater impact than the concern regarding privacy breaches in shaping perceived SNS risk.

本研究侧重于社交网站 (SNS) 用户的感知风险如何受到对 SNS 上潜在有害事件（网络攻击和隐私泄露）二元性的感知的影响，并探讨影响此类感知的潜在威胁源。此外，它还检查了感知风险对 SNS 成员站点使用的影响以及产生这些影响的潜在机制。研究发现，用户感知的 SNS 风险通过态度作为重要的中介来影响网站使用行为，并且用户对网络攻击（安全）的担忧比对隐私泄露的担忧在塑造感知 SNS 风险方面产生了更大的影响。
