中文摘要：

目的探讨军事心理应激水平与军人心理弹性、认知偏向及积极情绪的关系。方法采用军事心理应激自评问卷（PSET）、心理弹性量表（CD-RISC）中文版正负性情绪量表（PANAS-C）和正负性认知偏向量表（APNIS）对536名二炮某部官兵进行抽样调查。结果 1心理应激总分与负性情绪、负性认知偏向呈显著正相关（r值分别为0.44、0.41,P〈0.01）;与正性情绪、心理弹性和正性认知偏向均呈显著负相关（r值分别为-0.29、-0.30、-0.27,P〈0.01）。2心理应激高分组与低分组在心理弹性、正负性情绪、正负性认知偏向上均存在显著差异（P〈0.01）。3负性情绪、负性认知偏向、正性认知偏向和积极情绪可有效预测军事心理应激水平,总解释率为36%。4积极情绪在正性认知偏向对心理应激水平的影响中起部分中介作用,在心理弹性与心理应激水平之间起完全中介作用。结论军人心理应激水平与其心理弹性、正负性情绪和认知偏向密切相关。积极的情绪、合理的认知以及心理弹性的增加都有助于缓减军人心理应激症状,促进心理健康。

英文摘要：

Objective To explore the relationships of psychological stress with resilience, cognitive bias and positive affect in the militaries. Methods Psychological stress self-evaluation test （PSET）, Connor- Davidson resilience scale （ CD-RISC）, Chinese version of positive and negative affect schedule （ PANAS-C ） and attention to positive and negative information scale （APNIS） were used to survey 536 soldiers in the Second Artillery Force of Chinese People＇ s Liberation Army. Results The total score of psychological stress was positively correlated with negative affect and negative cognitive bias （ r = 0. 44 and 0.41, respectively, P 〈 0. 01 ） , and negatively correlated with positive affect, resilience and positive cognitive bias （r = -0. 29, -0.30 and -0.27, respectively, P 〈 0. 01 ）. There were significant differences in resilience, positive affect, negative affect, positive cognitive bias and negative cognitive bias between the psychological stress high-score group and the psychological stress low-score group （P 〈 0. 01 ）. Negative affect, negative cognitive bias, positive cognitive bias and positive affect were important predictors of psychological stress, and could explain 36% variance of psychological stress. Positive affect partially mediated the effect of positive cognitive bias on psychological stress, and totally mediated the relationship between resilience and psychological stress. Conclusion Military psychological stress is closely related with the resilience, cognitive bias, and positive and negative affect. Positive affect, rational cognition, and resilience improvement can help to relieve soldiers＇ psychological stress symptoms, reduce the negative affect and promote mental health.
