While perceived social support has received considerable research as a protective factor for suicide ideation, little attention has been given to the mechanisms that mediate its effects.
We integrated two theoretical models, Joiner's (2005) interpersonal theory of suicide and Leary's (Leary, Tambor, Terdal, & Downs, 1995) sociometer theory of self-esteem to investigate two hypothesized mechanisms, utilization of social support and self-esteem. Specifically, we hypothesized that individuals must utilize the social support they perceive that would result in increased self-esteem, which in turn buffers them from suicide ideation.
Participants were 172 college students who completed measures of social support, self-esteem, and suicide ideation.
Tests of simple mediation indicate that utilization of social support and self-esteem may each individually help to mediate the perceived social support/suicide ideation relationship. Additionally, a test of multiple mediators using bootstrapping supported the hypothesized multiple-mediator model.
The use of a cross-sectional design limited our ability to find true cause-and-effect relationships.
Results suggested that utilized social support and self-esteem both operate as individual moderators in the social support/self-esteem relationship. Results further suggested, in a comprehensive model, that perceived social support buffers suicide ideation through utilization of social support and increases in self-esteem.
虽然感知到的社会支持作为自杀意念的保护因素已经得到了相当多的研究,但对于其作用的机制却关注甚少。
我们整合了两个理论模型,即乔伊纳(2005 年)的人际自杀理论和利里(Leary)的自尊社会计量器理论,以探讨两个假设的机制,即利用社会支持和自尊。具体来说,我们假设个体必须利用他们感知到的社会支持,从而提高自尊,进而缓冲他们免受自杀意念的影响。
参与者是 172 名大学生,他们完成了社会支持、自尊和自杀意念的测量。
简单中介检验表明,利用社会支持和自尊都可能单独帮助中介感知到的社会支持与自杀意念之间的关系。此外,使用 bootstrap 的多中介检验支持了假设的多中介模型。
横断面设计的使用限制了我们发现真正因果关系的能力。
结果表明,利用社会支持和自尊在社会支持与自尊的关系中都作为个体的调节因素发挥作用。结果进一步表明,在一个综合模型中,感知到的社会支持通过利用社会支持和提高自尊来缓冲自杀意念。
