Posttraumatic stress disorder (PTSD) is associated with suicidal ideation and behavior, and is found to frequently co-occur with other conditions that exacerbate the risk for suicidal behavior. Despite these findings, few individuals with PTSD engage in suicidal acts, and there has been little research to examine those factors that protect against such behaviors. The current study used path analysis to examine the association among PTSD, depression, hazardous alcohol consumption, and beliefs about suicide (i.e., reasons for living) in a community sample with motor vehicle accident related-PTSD (N=50). Reasons for living were inversely associated with PTSD, depression, and alcohol use. Further, depression symptom severity accounted for the association between PTSD symptom severity and reasons for living. In contrast, hazardous alcohol consumption only demonstrated a trend for accounting for the association between PTSD and reasons for living. Our findings highlight the importance of clinicians assessing co-occurring depression symptoms and suggest the potential use of interventions that promote adaptive cognitions about suicide among people with PTSD.
创伤后应激障碍（PTSD）与自杀意念和行为相关，且发现常与其他加剧自杀行为风险的状况同时出现。尽管有这些发现，但很少有PTSD患者实施自杀行为，并且几乎没有研究去探究那些能预防此类行为的因素。本研究采用路径分析，在一个与机动车事故相关的PTSD社区样本（N = 50）中，考察PTSD、抑郁、有害饮酒及关于自杀的信念（即生存理由）之间的关联。生存理由与PTSD、抑郁及饮酒呈负相关。此外，抑郁症状严重程度解释了PTSD症状严重程度与生存理由之间的关联。相比之下，有害饮酒仅显示出在解释PTSD与生存理由之间的关联方面有一定趋势。我们的研究结果凸显了临床医生评估共病抑郁症状的重要性，并提示了在PTSD患者中促进对自杀产生适应性认知的干预措施的潜在用途。
