特里尔社会应激测验对儿童皮质醇分泌的影响

研究以32名小学儿童（平均年龄10.47岁，男生16人）为被试，采用唾液皮质醇为应激测验的客观指标、以被试主观紧张度为主观指标，考察特里尔社会应激测验对中国儿童皮质醇分泌的影响。结果表明：（1）社会应激测验任务引发儿童皮质醇浓度和主观紧张度的显著上升，任务后的恢复期皮质醇浓度和主观紧张度能够恢复到任务前的水平。（2）社会应激测验任务引发的男生皮质醇水平变化显著高于女生，但是引发的主观紧张度水平变化不存在显著性别差异。社会应激测验中文修订版能够有效引发儿童的压力应激变化，可以用其开展儿童社会应激的相关研究。

Impact of Trier Social Stress Test on Children Salivary Cortisol Secretion

Trier Social Stress Test (TSST) is a widely used psychosocial stress paradigm conducted in 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 children sample. Therefore, in the present study, healthy boys and girls (n=32, mean age=10.47) performed the modified TSST protocol according to Chinese children, during which the subjective stress level and salivary cortisol level were assessed. The results showed that participants exhibited a significant increase in salivary cortisol, and reported more anxiety immediately following the TSST compared to baseline. Furthermore, while boys and girls differ with respect to salivary cortisol to TSST, boys generated higher levels of salivary cortisol compared to girls. The findings demonstrated that the modified TSST is a protocol with good applicability in Chinese children participants and could be used to conduct psychosocial stress research in China.
