军人急性心理应激反应的影响因素研究

目的 探讨战场应激源与战时急性心理应激反应之间存在的中介因素及其对军人战时心理应激反应的影响.方法 用心理测验法和试验法调查683名被试的心理中介因素和急性心理应激反应情况.结果 心理健康军人的应激反应总分(59.21±5.42)分,(54.85±7.92)分,P=0.049]和情绪反应分量表(17.21±1.36)分,(14.15±2.71)分,P=0.048]得分显著高于心理异常军人;心理健康并表现出积极心理应激反应军人的一些人格特征(H8、Pt、Sc、Si、Mas、Dy、Do、Re)明显比消极应激反应军人健全、消极应对(Nc)得分显著低于消极应激反应军人(t=2.148.P=0.035)、自我效能(108.63±20.31)分,(94.65±17.10)分,P=0.001]和战争认知(54.37±4.45)分,(50.95±6.06)分,P=0.005]显著高于消极应激反应军人;在影响急性应激反应诸因素中,人格的情绪稳定性(Pt、Mas)和战争认知进入回归方程.结论 证实了在战场应激源与急性应激心理反应之间存在心理健康、人格特征、自我效能、应对方式、战争认知5个中介因素,其中人格的情绪稳定性和战场认知是最核心的影响因素.

Study on influential factors on army men's acute psychological stress response during war

Objective To explore how many psychological mediators there were between war stressor and acute war stress response and how these mediators made an impact on acute war stress response.Methods Five mediators were assessed by relevant questionnaires,and acute stress psychological response was measured by means of designing an experiment in 683 freshmen of military colleges.Results Subjects with sound mental health had higher total stress response scale and emotion response subscale scores than ones with abnormal mental health(t=2.083,2.148)(P=0.049,0.048).Among mentally healthy subjects,ones with positive stress response had better personality features(especially in Hs,Pt,Sc,Si,Mas,Dy,Do,Re),and lower Nc scores(t=2.148,P=0.035),and also higher self-efficiency and war cognition scores(t=3.348,2.896)(P=0.001,0.005)than ones with negarive stress response.Among all factors mentioned above,instability of affect(in Pt,Mas)and war cognition got into regression equation.Conclusion The research confirmed that there are mental health,personality feature,coping style,self-efficiency,war cognition 5 mediators,and these mediators play different roles in influencing acute stress response,and also instability of affect and war cognition are the best predictors.
