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.

普通人群中成年人自杀意念经历中的冒险，抑郁和饮酒之间的关系。

冒险与沮丧的青少年自杀有关。在美国，酒精是最需要治疗的最常用物质之一。尽管饮酒会导致更大的抑郁和自杀倾向，但人们对这些与冒险倾向的关系所知甚少，尤其是在成年人群中。本研究调查了参加2017年全国药物使用和健康调查的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中的特定目标。共有1,740（21.4％）位参与者支持自杀意念。该模型显示出良好的拟合度，研究结果表明，酗酒或依赖性（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）均与想法可能性增加有关。酗酒或依赖性增加（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增加有关。根据联合显着性检验，冒险倾向是部分调解人，是饮酒，抑郁和观念之间关系的一种机制。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）也与较高的冒险精神有关。根据联合显着性检验，冒险倾向是部分调解人，是饮酒，抑郁和观念之间关系的一种机制。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）也与较高的冒险精神有关。根据联合显着性检验，冒险倾向是部分调解人，是饮酒，抑郁和观念之间关系的一种机制。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。
