Abstract
The objective of this study was to estimate a network model of risk and resilience factors of suicidal ideation among veterans. Two network models of suicidal ideation among Operation Iraqi Freedom/Operation Enduring Freedom/Operation New Dawn veterans ( = 276) incorporated key disorders, traumatic stress, and resilience constructs to contextualize suicidal ideation. Childhood trauma was positively connected with suicidal ideation and harassment and inversely connected with social support and distress tolerance. This exemplifies long-lasting associations between childhood trauma and re-victimization, emotion regulation, and ability to form supportive social relationships. A subsequent model including lower-order facets indicated that combat trauma was predominantly associated with posttraumatic stress disorder-intrusion symptoms. This study highlights the importance of addressing both risk and resilience to reduce suicide risk among veterans and increases understanding of factors that contribute to suicidal ideation.
摘要
本研究的目的是评估退伍军人自杀意念的风险和复原力因素的网络模型。两个关于伊拉克自由行动/持久自由行动/新黎明行动退伍军人（n = 276）自杀意念的网络模型纳入了关键疾病、创伤应激和复原力结构，以将自杀意念置于情境中。童年创伤与自杀意念和骚扰呈正相关，与社会支持和痛苦耐受性呈负相关。这例证了童年创伤与再次受害、情绪调节以及形成支持性社会关系能力之间的长期关联。随后一个包含低阶层面的模型表明，战斗创伤主要与创伤后应激障碍的侵入性症状相关。本研究强调了应对风险和复原力以降低退伍军人自杀风险的重要性，并增进了对导致自杀意念的因素的理解。
