Despite the general suicide rate within the military being comparable to the general population when comparing peers, there are certain branches of the military that have elevated risk. Specifically, the U.S. National Guard has suicide rates that are constantly higher than other military branches and civilian peers. The National Guard are a unique military population in which they frequently transition between military and civilian life. With these unique experiences and heightened risk, military suicide prevention efforts may benefit from further research within this population. Posttraumatic stress disorder (PTSD) is another concern amongst military personnel and has been linked to suicidal behavior.
The current study examined the indirect effects that distress tolerance, a protective factor against suicide, has on the relationship between PTSD and constructs within a well-validated theory for suicide (the Interpersonal-Psychological Theory for suicidal behaviors) in a sample of U.S. Army National Guard personnel.
Results indicated that distress tolerance had a significant indirect effect on the relationship between PTSD and thwarted belongingness, perceived burdensomeness, and capability for suicide.
These findings are consistent with previous literature examining the relationship between distress tolerance and our outcome variables. These results could have important clinical implications, mainly that intervention strategies targeting distress tolerance could have significant impacts on suicide-relate thoughts.
尽管在比较同龄人时，军队的总体自杀率与普通人群相当，但某些军种确实存在更高的风险。具体来说，美国国民警卫队的自杀率一直高于其他军种和普通民众。国民警卫队是一个独特的军事群体，他们经常在军队和民间生活之间转换。鉴于这些独特的经历和更高的风险，预防军人自杀的努力可能需要在这一群体中进行进一步的研究。创伤后应激障碍（PTSD）也是军人关注的另一个问题，并且与自杀行为有关。
本研究在一个美国陆军国民警卫队人员样本中，检验了一种保护因素——即痛苦耐受力，对创伤后应激障碍与自杀行为的一个具有良好验证性理论（人际心理理论对自杀行为）中某些结构之间关系的间接影响。
结果表明，痛苦耐受力对创伤后应激障碍与归属感受挫、感知负担过重和自杀能力之间的关系具有显著的间接影响。
这些发现与先前研究痛苦耐受力与我们的结果变量之间关系的文献一致。这些结果可能具有重要的临床意义，主要是针对痛苦耐受力的干预策略可能会对与自杀相关的想法产生重大影响。
