Despite the well-established link between firearm access and suicide, less is known about other variables that may influence the risk for death by self-inflicted gunshot versus other methods of suicide. As individual factors have demonstrated limited predictive ability, scholars have called for studies that consider the multifaceted relations between myriad variables. One alternative to the typical cause-and-effect approach for investigating various forms of psychopathology is network analysis. However, few studies have applied this method to suicidal outcomes, particularly in the context of a veteran population. Data from 19,234 male veteran suicide decedents (89.1% White; Mage = 57.16, SD = 18.64) acquired from the National Violent Death Reporting System were used to investigate characteristics of veteran suicide decedents who died by self-inflicted gunshot (gun; 66.4%) versus alternative methods (nongun, e.g., poisoning, hanging; 33.5%). Results of the overall moderated network model indicated that veterans in the gun group were more likely to have a physical health problem that contributed to the suicide than veterans in the nongun group. Additionally, results of the moderated network model revealed several pairs of associated circumstances whose relationships were significantly moderated by method of suicide, the three strongest of which included having a physical health problem that contributed to the suicide. Overall, results suggest that public health prevention and intervention efforts aimed at reducing the overall burden of physical health problems among male veterans may mitigate the risk of firearm suicides.

通过退伍军人自杀方法比较风险因素的相互作用：一种有调节的网络分析方法。


尽管枪支使用与自杀之间存在明确的联系，但与其他自杀方法相比，可能影响自伤枪击死亡风险的其他变量却知之甚少。由于个别因素的预测能力有限，学者们呼吁进行研究，考虑无数变量之间的多方面关系。用于研究各种形式的精神病理学的典型因果方法的一种替代方法是网络分析。然而，很少有研究将这种方法应用于自杀结果，特别是在退伍军人群体的背景下。使用从国家暴力死亡报告系统获取的 19,234 名男性退伍军人自杀死者（89.1% 白人；法师 = 57.16，SD = 18.64）的数据来调查因自残枪杀（枪；66.4%）而死亡的退伍军人自杀死者的特征与替代方法（nongun，例如投毒、绞刑；33.5%）。整体调节网络模型的结果表明，持枪组的退伍军人比非持枪组的退伍军人更有可能出现导致自杀的身体健康问题。此外，调节网络模型的结果揭示了几对相关情况，其关系因自杀方法而显着调节，其中最严重的三对包括导致自杀的身体健康问题。总体而言，结果表明，旨在减轻男性退伍军人身体健康问题总体负担的公共卫生预防和干预措施可能会降低枪支自杀的风险。 （PsycInfo 数据库记录 (c) 2024 APA，保留所有权利）。
