This study examines the SNS activities of Singaporean women to assess how they perceive the risk of Zika virus infection based on the consumption of Zika-related news. Results from an online survey (N = 510) confirmed that third-person risk perception exists among study participants. Individual posting of ZIKA-related news on SNSs was negatively associated with third-person perception. Additionally, third-person perception was negatively correlated with preventive behavioral intention. A moderated mediation model analysis revealed that attention to ZIKA-related news on SNSs significantly moderates the indirect relationship between posting news of ZIKA on SNSs and preventive behavioral intention. The findings of this study are expected to increase the understanding of the third-person effect in the context of infectious diseases based on users’ SNS activities.

本研究调查了新加坡女性的 SNS 活动，以评估她们如何根据对寨卡病毒相关新闻的消费感知感染寨卡病毒的风险。在线调查的结果 ( N= 510) 确认研究参与者中存在第三人称风险感知。个人在 SNS 上发布与寨卡病毒相关的新闻与第三人称感知呈负相关。此外，第三人称感知与预防行为意图呈负相关。调节中介模型分析显示，对 SNS 上 ZIKA 相关新闻的关注显着调节了在 SNS 上发布 ZIKA 新闻与预防行为意图之间的间接关系。预计本研究的结果将增加对基于用户 SNS 活动的传染病背景下的第三人称效应的理解。
