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.
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 path x path product.
Consistent with prior work, we found a significant positive association between SI and frequency of risky behavior ( = .49). We found significant indirect effects of SI on risky behavior through impulsivity and wish to live but not through hopelessness.
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.
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）与危险行为之间关系的因素。这项预先注册的研究检验了 SI 与危险行为之间的关系，以及通过无望、冲动和生活意愿低是否存在间接关系。这些因素被选中是因为它们与 SI 和危险行为都有关系。
从亚马逊 Mechanical Turk 招募的参与者完成了自杀意念、危险行为、无望、冲动和生活意愿的测量。符合我们预先注册的方法，我们分析了来自 180 名有有效数据的参与者的数据。通过对路径 x 路径乘积的 5000 个样本进行.bootstrap 分析，评估了间接效应。
与先前的工作一致，我们发现 SI 与危险行为的频率之间存在显著的正相关（ =.49）。我们发现 SI 通过冲动和生活意愿对危险行为有显著的间接影响，但通过无望没有。
SI 和危险行为通过冲动和生活意愿相互关联。尽管未来需要进行纵向研究来确定因果关系，但这对自杀思维和行为模型及其与危险行为的关系具有重要意义。未来取向解释结果的潜力也进行了讨论。
