特里尔社会应激测试(TSST)对唾液皮质醇分泌的影响

Impact of Trier Social Stress Test(TSST) on Salivary Cortisol Secretion

特里尔社会应激测试(Trier Social Stress Test:TSST)是国外应用广泛的社会心理应激测试手段,然而还没有研究对其在中国的适用性进行报告。本研究以健康大学生为被试,分别采用主观应激报告(简明心境量表和5点量表)和客观应激参数(心率和唾液皮质醇)为指标,探讨TSST在中国的适用情况以及性别因素对个体在TSST应激情境中的影响。结果发现,TSST诱发了中国被试显著的应激反应,在经历了TSST情境后,被试主观报告紧张水平增加,同时心跳加速,唾液皮质醇水平增加。即使女性被试主观报告紧张与不安的程度显著高于男性,但是男性和女性在TSST应激情境下的心跳和唾液皮质醇指标没有差异。研究结果提示,TSST在中国被试中具有良好的适用性,可以利用其开展与社会心理应激相关的研究。男女被试在与成就动机相关的应激源(例如,TSST)中的客观应激参数差异不明显。

Trier Social Stress Test（TSST） is a widely used psychosocial stress paradigm conducted in a laboratory setting which has been shown to reliably elicit a physiological stress response in various study samples.However,no study to date has investigated the responses to the TSST in Chinese sample.Therefore,in the present study,healthy male and female volunteers（N=30） performed the standardized TSST protocol,during which several subjective measures（Profile of Mood State and the visual rating scale） and objective measures（heart rate and salivary cortisol） were assessed.The results showed that participants exhibited a significant increase in heart rate and salivary cortisol,and reported more anxiety immediately following the TSST compared to baseline.Furthermore,while men and women did not differ with respect to physiological response to TSST,women did report higher levels of anxiety compared to men.The findings demonstrated that TSST is a protocol with good applicability in Chinese participants and could be used to conduct psychosocial stress research in China.Sex differences failed to reliably discriminate between male and female in objective measures to stressors which were achievement-oriented.
