The interpersonal theory of suicide (ITS) may explain the link between alcohol use severity and suicidal ideation (SI) through interpersonal stressors at elevated alcohol use levels. This study aimed to clarify the indirect effects of perceived burdensomeness (PB) and thwarted belongingness (TB) in this relationship. Cross-sectional data on SI, ITS, and alcohol use severity variables were collected via an online sample ( = 299) screened for lifetime suicidal thoughts or behaviors, nonsuicidal self-injury, and alcohol use. Associations were tested using linear regression with parallel mediators. Alcohol use severity was indirectly linked to SI through the unique indirect effect of PB, and the total indirect effect of both TB and PB. Limitations include the cross-sectional design and use of an online sample, which limit causal inferences and generalizability to other high-risk populations. PB and the additive indirect effect of TB and PB may explain the positive relation between alcohol use and SI; implications are discussed.
自杀人际理论（ITS）或许可以通过酒精使用水平升高时的人际压力源来解释酒精使用严重程度与自杀意念（SI）之间的联系。本研究旨在阐明感知负担（PB）和归属感受挫（TB）在此关系中的间接影响。通过对有过终身自杀想法或行为、非自杀性自我伤害及酒精使用情况进行筛查的在线样本（n = 299）收集关于SI、ITS和酒精使用严重程度变量的横断面数据。使用带有平行中介变量的线性回归来检验相关性。酒精使用严重程度通过PB的独特间接效应以及TB和PB的总间接效应与SI间接相关。局限性包括横断面设计和在线样本的使用，这限制了因果推断以及对其他高危人群的普遍性。PB以及TB和PB的累加间接效应或许可以解释酒精使用与SI之间的正向关系；对此进行了讨论。
