Risk-taking is associated with suicide among depressed adolescents. In the United States, alcohol is among the most used substances resulting in need for treatment. While alcohol use relates to greater depression and suicidality, less is known about these relationships with risk-taking tendencies, particularly among adult populations. The current study examined suicidal ideation, alcohol use, depression, and risk-taking tendencies among adults 18-65 years old who participated in the 2017 National Survey on Drug Use and Health. Structural equation modeling was used to examine the specific aims in Mplus8. A total of 1,740 (21.4%) participants endorsed suicidal ideation. The model demonstrated good fit and findings indicate increases in alcohol abuse or dependence (b = 0.094, SE = 0.01, p < .001), depression (b = 0.036, SE = 0.01, p < .001), and risk-taking (b = 0.044, SE = 0.01, p < .001) all independently related to increased odds of ideation. Increases in alcohol abuse or dependence (b = 0.210, SE = 0.02, p < .001) and depression (b = 0.026, SE = 0.01, p < .05) also related to elevated risk-taking. Based on the joint significance test, risk-taking tendencies served as a partial mediator, functioning as a mechanism in the relationships between alcohol use, depression, and ideation. Risk-taking thus serves as an important treatment target in the prevention of suicide. Implications for practice and future research are discussed.

一般人群中成人自杀意念经历中冒险、抑郁和酒精使用之间的关系。

冒险与抑郁青少年的自杀有关。在美国，酒精是需要治疗的最常用物质之一。虽然酒精使用与更大的抑郁症和自杀率有关，但人们对这些与冒险倾向的关系知之甚少，尤其是在成年人群中。目前的研究调查了参加 2017 年全国药物使用与健康调查的 18-65 岁成年人的自杀意念、饮酒、抑郁和冒险倾向。结构方程模型用于检查 Mplus8 中的具体目标。共有 1,740 名 (21.4%) 参与者支持自杀意念。该模型表现出良好的拟合度，研究结果表明酒精滥用或依赖增加（b = 0.094，SE = 0.01，p < .001），抑郁症（b = 0.036，SE = 0.01，p < .001），和冒险（b = 0.044，SE = 0.01，p < .001）都与增加的构思几率独立相关。酗酒或依赖（b = 0.210，SE = 0.02，p < .001）和抑郁症（b = 0.026，SE = 0.01，p < .05）的增加也与冒险行为的增加有关。基于联合显着性检验，冒险倾向作为部分中介，在酒精使用、抑郁和观念之间的关系中发挥作用。因此，冒险是预防自杀的重要治疗目标。讨论了对实践和未来研究的影响。05) 也与高风险承担有关。基于联合显着性检验，冒险倾向作为部分中介，在酒精使用、抑郁和观念之间的关系中发挥作用。因此，冒险是预防自杀的重要治疗目标。讨论了对实践和未来研究的影响。05) 也与高风险承担有关。基于联合显着性检验，冒险倾向作为部分中介，在酒精使用、抑郁和观念之间的关系中发挥作用。因此，冒险是预防自杀的重要治疗目标。讨论了对实践和未来研究的影响。
