Wildland firefighters are posited to have a higher suicide rate than general firefighters and the general population. However, the rates and risk factors of suicide among wildland firefighters is not fully understood.
For this preregistered study, 564 participants were recruited from Facebook to obtain a final sample of 246 participants with valid data who were current or former wildland firefighters in the United States. Participants completed online measures of suicidal ideation, history of suicidal behaviors, posttraumatic stress disorder (PTSD) symptoms, problematic alcohol use, and occupational exposure to suicide.
In this sample, 22% of wildland firefighters reported a history of at least one suicide attempt, and 36.7% reported current suicidal ideation. PTSD symptoms, but not problematic alcohol use or exposure to suicide, were positively associated with suicidal ideation and a history of suicide attempts. Additionally, PTSD symptoms explained significantly more variance in suicidal ideation than depression symptoms alone.
Wildland firefighters demonstrate rates of suicide attempts that exceed those of non-wildland firefighters and of the general population at large. In addition, PTSD symptoms may contribute to suicidal thoughts and behaviors (STB) in this population. This is the largest study of STB in wildland firefighters to date.
据推测，野外消防员的自杀率高于普通消防员和普通人群。然而，野外消防员自杀的发生率及风险因素尚未完全明确。
在这项预先注册的研究中，通过脸书招募了564名参与者，最终获得了246名有效数据的参与者样本，这些参与者均为美国现役或退役的野外消防员。参与者完成了关于自杀意念、自杀行为史、创伤后应激障碍（PTSD）症状、酒精使用问题以及职业性自杀暴露的在线测评。
在这个样本中，22%的野外消防员报告至少有过一次自杀未遂史，36.7%报告有当前自杀意念。PTSD症状与自杀意念和自杀未遂史呈正相关，而酒精使用问题或自杀暴露则不然。此外，PTSD症状单独解释自杀意念的变异显著多于抑郁症状。
野外消防员的自杀未遂率超过非野外消防员及普通人群。此外，PTSD症状可能导致该人群出现自杀想法和行为（STB）。这是迄今为止关于野外消防员STB的最大规模研究。
