人格特质对个体心理性应激反应的调节作用

心理性应激是个体的内稳态受到社会心理威胁时候的状态。面对急性心理性应激源, 有机体的各大机能系统, 包括神经内分泌系统、免疫系统以及自主神经系统等, 会出现一系列生物功能的改变。已有研究表明人格特质(如自尊、特质焦虑和大五人格)会影响个体在心理性应激情境中的反应差异且影响方式尚不统一, 并且不同文化环境下人格特质影响心理性应激反应的方式是不一样的, 然而这种结果的差异有可能是生物标记物的不一致造成的, 也有可能是心理性应激任务的不一致造成的, 不能直接进行比较。未来研究应该在控制这些无关变量的基础上, 从跨文化的角度去考察人格特质对个体心理性应激反应差异的影响。

The Modulation Effect of Personality Traits on the #br# Psychosocial Stress Response

Psychosocial stress has been defined as a state of threatened homeostasis by the psychosocial threat. Acute stress can alter numerous biological functions, such as the neuroendocrine system, the immune system and the autonomic nerves system. Previous studies have indicated that personality traits, such as self-esteem, trait anxiety and the big five personality, play a key role in modulating the psychosocial stress responses, and the patterns of the modulation effect are contradictory in different cultures. However, these inconsistent results may be caused either by the different biological markers or by the different stress protocols, which hinder the direct comparisons. Future research should try to explore the impact of personality traits on the psychosocial stress response in a cross-culture view, while control these unrelated variables.
