Abstract

Objective

Numerous studies have found support for the relationship between suicide and risky behavior. However, few studies have examined factors that may help explain the relationship between suicidal ideation (SI) and risky behavior. This preregistered study examined the relationship between SI and risky behavior and whether there is an indirect relationship through hopelessness, impulsivity, and low wish to live. These factors were selected due to their relationships with both SI and risky behavior.

Methods

Participants recruited from Amazon Mechanical Turk completed measures of SI, risky behavior, hopelessness, impulsivity, and wish to live. Consistent with our preregistered methods, we analyzed data from 180 participants with valid data. Indirect effects were evaluated via bootstrapping with 5000 resamples of the a path x b path product.

Results

Consistent with prior work, we found a significant positive association between SI and frequency of risky behavior (r = .49). We found significant indirect effects of SI on risky behavior through impulsivity and wish to live but not through hopelessness.

Conclusion

SI and risky behavior are associated with each other through impulsivity and wish to live. Though future longitudinal research is needed to determine causality, this has important implications for models of suicidal thoughts and behaviors and their relationship with risky behavior. The potential of future orientation to explain the results is discussed.

自杀意念和危险行为与冲动和求生意愿低有关

摘要

客观的

许多研究都支持自杀与危险行为之间的关系。然而，很少有研究探讨可能有助于解释自杀意念（SI）和危险行为之间关系的因素。这项预先注册的研究考察了 SI 和危险行为之间的关系，以及是否存在通过绝望、冲动和低生活意愿之间的间接关系。选择这些因素是因为它们与 SI 和危险行为都有关系。

方法

从 Amazon Mechanical Turk 招募的参与者完成了 SI、危险行为、绝望、冲动和生存意愿的测量。按照我们预先注册的方法，我们分析了 180 名具有有效数据的参与者的数据。通过对a路径 x b路径乘积进行 5000 次重采样进行引导来评估间接影响。

结果

与之前的工作一致，我们发现 SI 与危险行为频率之间存在显着的正相关关系 ( r = .49)。我们发现，SI 对冲动和求生欲望产生的危险行为有显着的间接影响，但对绝望没有影响。

结论

SI 和危险行为通过冲动和生存愿望相互关联。尽管未来需要纵向研究来确定因果关系，但这对于自杀想法和行为的模型及其与危险行为的关系具有重要意义。讨论了未来方向解释结果的潜力。
