The construct of violence has scarcely been researched in relation to suicidality in Mexico. The aim of the present study was to explore the role of different types of violence (e.g., violence at home, non-suicidal self-injury) in suicidal behaviour (e.g., suicidal ideation, suicidal acts) of the citizens of the Yucatan State using a massive online screening approach through a smartphone application. A prospective cohort study design was undertaken during 2022 including 32,531 Mexican participants aged between 15 and 80 years old, which constituted the second wave of the SmartScreen project, through the TEDUCA survey. We selected as the main variables violence at home, non-suicidal self-injuries, and suicidal behaviour (Columbia-Suicide Severity Rating Scale; C-SSRS). A set of univariate regression analyses was performed for the entire sample connecting the variables with the C-SSRS. Subsequently, a multiple linear regression model was used. The model explained a significant portion of the variance in C-SSRS scores (adj = 0.3227) indicating the following as predictors affecting suicidality: perceived violence at home, followed by a history of NSSI, and previous mental health service attendance, among other associations between the sociodemographic predictors and suicidal behaviour. Significant interactions between perceived violence and NSSI history were also found. In conclusion, our study highlights the significant role of perceived violence at home and NSSI history in shaping suicide risk understood as the ideation and intention of suicidality among Yucatan citizens. The interaction between these factors and sociodemographic variables such as gender and age underscore the complex nature of suicide risk.
在墨西哥，针对暴力与自杀倾向之间的关系几乎没有相关研究。本研究的目的是通过智能手机应用程序，采用大规模在线筛查方法，探讨不同类型的暴力（如家庭暴力、非自杀性自伤）在尤卡坦州公民自杀行为（如自杀意念、自杀行为）中的作用。2022年开展了一项前瞻性队列研究，纳入了32531名年龄在15至80岁之间的墨西哥参与者，这构成了SmartScreen项目的第二波，通过TEDUCA调查进行。我们选取家庭暴力、非自杀性自伤和自杀行为（哥伦比亚自杀严重程度评定量表；C-SSRS）作为主要变量。对整个样本进行了一组单变量回归分析，将这些变量与C-SSRS联系起来。随后，使用了多元线性回归模型。该模型解释了C-SSRS分数中很大一部分方差（调整后=0.3227），表明以下因素是影响自杀倾向的预测因素：感知到的家庭暴力，其次是非自杀性自伤史和以前接受过心理健康服务，以及社会人口统计学预测因素与自杀行为之间的其他关联。还发现了感知暴力与非自杀性自伤史之间的显著相互作用。总之，我们的研究强调了感知到的家庭暴力和非自杀性自伤史在塑造自杀风险方面的重要作用，自杀风险在尤卡坦州公民中被理解为自杀意念和意图。这些因素与性别和年龄等社会人口统计学变量之间的相互作用突显了自杀风险的复杂性。
