Emotion-based impulsivity (EBI) and hazardous drinking have consistently been associated with elevated negative thoughts related to suicide ideation (N-SI); however, the interaction between these risk factors has not been tested empirically. Thus, we tested the moderating effect of hazardous drinking on the relation between EBI and N-SI in a high-risk adult sample.
Cross-sectional, self-report data were used from adults ( = 329, = 36.61 years, = 11.38) screened for elevated suicide risk and previous alcohol use via Amazon's Mechanical Turk crowdsourcing platform.
Bivariate correlations indicated significant positive associations between EBI, hazardous drinking, and N-SI. Furthermore, hazardous drinking moderated the relation between EBI and N-SI, such that the association between EBI and N-SI was stronger among those with more severe hazardous drinking. This moderation effect was robust to the inclusion of additional covariates.
This study demonstrated that hazardous drinking strengthens the association between EBI and N-SI among adults with elevated suicide risk and previous alcohol use. These findings underscore the need for clinicians to fully evaluate the drinking behaviors of individuals at risk for suicide. Further directions for research are discussed.
基于情绪的冲动性（EBI）和危险饮酒一直与自杀观念相关的消极思维（N-SI）增加有关；然而，这些风险因素之间的相互作用尚未得到实证检验。因此，我们在一个高危成人样本中检验了危险饮酒对EBI与N-SI之间关系的调节作用。
通过亚马逊的Mechanical Turk众包平台，对有自杀风险升高和既往饮酒史的成年人（n = 329，年龄 = 36.61岁，标准差 = 11.38）进行横断面自我报告数据收集。
双变量相关性表明EBI、危险饮酒和N-SI之间存在显著正相关。此外，危险饮酒调节了EBI与N-SI之间的关系，即在危险饮酒更严重的人群中，EBI与N-SI之间的关联更强。这种调节效应在纳入其他协变量后依然稳健。
本研究表明，在有自杀风险升高和既往饮酒史的成年人中，危险饮酒会加强EBI与N-SI之间的关联。这些发现强调临床医生需要全面评估有自杀风险个体的饮酒行为。还讨论了进一步的研究方向。
