A limited number of studies have examined the differences in suicide-related social media use behaviors between suicide ideators and suicide attempters or have sought to elucidate how these social media usage behaviors contributed to the transition from suicidal ideation to suicide attempt.
Suicide attempts can be acquired through suicide-related social media use behaviors. This study aimed to propose 3 suicide-related social media use behaviors (ie, attending to suicide information, commenting on or reposting suicide information, or talking about suicide) based on social cognitive theory, which proposes that successive processes governing behavior transition include attentional, retention, production, and motivational processes.
We aimed to examine the mediating role of suicide-related social media use behaviors in Chinese social media users with suicidal risks. A sample of 569 Chinese social media users with suicidal ideation completed measures on suicidal ideation, suicide attempt, and suicide-related social media use behaviors.
The results demonstrated that suicide attempters showed a significantly higher level of suicidal ideation (t=5.04; P<.001; two-tailed) and more suicide-related social media use behaviors, which included attending to suicide information (t=1.94; P=.05; two-tailed), commenting on or reposting suicide information (t=2.12; P=.03; two-tailed), or talking about suicide (t=5.12; P<.001; two-tailed). Suicidal ideation also affected suicide attempts through the mediational chains.
Our findings thus support the social cognitive theory, and there are implications for population-based suicide prevention that can be achieved by identifying behavioral signals.
仅有少数研究考察了有自杀意念者与自杀未遂者在与自杀相关的社交媒体使用行为上的差异，或试图阐明这些社交媒体使用行为是如何促使从自杀意念转变为自杀未遂的。
自杀未遂可能通过与自杀相关的社交媒体使用行为习得。本研究旨在基于社会认知理论提出3种与自杀相关的社交媒体使用行为（即关注自杀信息、评论或转发自杀信息、谈论自杀），该理论提出，支配行为转变的连续过程包括注意、保持、产生和动机过程。
我们旨在考察与自杀相关的社交媒体使用行为在中国有自杀风险的社交媒体用户中的中介作用。对569名有自杀意念的中国社交媒体用户进行抽样，完成了关于自杀意念、自杀未遂及与自杀相关的社交媒体使用行为的测量。
结果表明，自杀未遂者的自杀意念水平显著更高（t=5.04；P<.001；双侧），且有更多与自杀相关的社交媒体使用行为，包括关注自杀信息（t=1.94；P=.05；双侧）、评论或转发自杀信息（t=2.12；P=.03；双侧）或谈论自杀（t=5.12；P<.001；双侧）。自杀意念也通过中介链影响自杀未遂。
因此，我们的研究结果支持社会认知理论，且对通过识别行为信号实现基于人群的自杀预防具有启示意义。
