背景紧急服务人员经常在事故或灾难中面临死亡。因此，他们可能更容易经历创伤后应激障碍(PTSD)和抑郁症。这些共病与人格特征和生活质量(QOL)有关。方法我们假设精神障碍，如创伤后应激障碍(PTSD)和抑郁症状，在10项人格问卷(TPI)上测量的人格特征和MOS 36项简明健康调查(SF-36)中的生活质量之间起中介作用。向373名参与者发出了问卷，其中220人回复了答案。TIPI的两个子量表(外倾性和情绪稳定性)与SF-36的心理成分总分(外向性：β=0.154，P&t；0.179；情绪稳定性：β=0.179，P&t；001)之间存在直接效应，表明部分中介作用。两种人格特质与心理健康总分之间存在显著的间接效应(外倾性：β=0.058，p<；0.087；情绪稳定性：β=0.087，p<；2.001)。我们还发现TIPI的外倾性分数对SF-36的角色/社会成分总分有直接影响(β=0.084，p<；10.05)。然而，95%的保密区间均不显著，表明完全调解，间接影响显著(β=0.023，P<；01)。敏感性分析表明，TIPI的外倾性得分与SF-36的角色/社会成分总分之间存在显著的直接效应，具有部分中介作用。结论直接效应和间接效应的研究结果突出了寻找有效方法预防创伤后应激障碍和抑郁的重要性，并有助于提高生活质量。应急服务人员处理突发事件的能力可能会因其个性特征而异。因此，包括人格特质问卷在内的精神健康状况筛查可能是有价值的。
BackgroundEmergency service workers are often exposed to fatalities during accidents or disasters. Therefore, they may be more prone to experiencing posttraumatic stress disorder (PTSD) and depression. It has been shown that these comorbid disorders are related to personality traits and quality of life (QOL).MethodsWe hypothesized that mental disorders, such as symptoms of PTSD and depression, mediate the relationship between personality traits, as measured on the 10-Item Personality Inventory (TIPI), and QOL, as measured on the MOS 36-item Short-Form Health Survey (SF-36).ResultsParticipants were aged 23–61 years. Questionnaires were sent to 373 participants, 220 of whom returned responses. A direct effect was found between two subscales of the TIPI (Extraversion and Emotional stability) and mental component summary scores of the SF-36 (Extraversion: β = 0.154,p< .001; Emotional stability: β = 0.179,p< .001), which indicated partial mediation. A significant indirect effect was revealed between two personality traits and mental health summary scores (Extraversion: β = 0.058,p< .001; Emotional stability: β = 0.087,p< .001). We also found a direct effect of extraversion scores of the TIPI on role/social component summary scores of the SF-36 (β = 0.084,p< .05). However, none of the 95% confidential intervals was significant, which indicated full mediation, and the indirect effect was significant (β = 0.023,p< .01). Sensitivity analysis indicated that a direct effect between extraversion scores of the TIPI and role/social component summary scores of the SF-36 was significant, which indicated partial mediation.ConclusionsThe findings of direct and indirect effects highlight the importance of identifying effective methods for protecting individuals from developing symptoms of PTSD and depression; moreover, they may help improve QOL. The capacity of dealing with incidents among emergency service workers may vary depending on their personality traits. Therefore, the screening of mental health states that includes a personality trait inventory may be valuable.
