In stress research, economic instruments for introducing acute stress responses are needed. In this study, we investigated whether the socially evaluated cold-pressor group test (SECPT-G) induces salivary alpha-amylase (sAA) and/or cortisol responses in the general population and whether this is associated with anthropometric, experimental, and lifestyle factors.
A sample of 91 participants from the general population was recruited. Salivary cortisol and sAA levels were assessed prior to ( ), immediately after ( ), and 10 min after the SECPT-G ( ).
A robust cortisol increase was found immediately after the SECPT-G, which further increased between and . This was independent of most of the control variables. However, men showed a trend toward higher cortisol increases than women ( = 0.005). No sAA responses were found at all. However, sAA levels were dependent on measurement time point with highest levels between 9 pm and 9:30 pm. Participants who immersed their hands into the ice water for the maximally allowed time of 3 min showed higher sAA levels at all time points than participants who removed their hands from the water earlier.
We conclude that the SECPT-G is a good means of an acute stress test when cortisol-but not necessarily sAA-responses are intended.
在应激研究中，需要用于引发急性应激反应的经济工具。在本研究中，我们调查了社会评价冷加压组测试（SECPT - G）是否会在普通人群中诱导唾液α -淀粉酶（sAA）和/或皮质醇反应，以及这是否与人体测量学、实验和生活方式因素相关。
招募了91名普通人群的参与者样本。在SECPT - G之前（ ）、之后立即（ ）以及之后10分钟（ ）评估唾液皮质醇和sAA水平。
在SECPT - G之后立即发现皮质醇有显著增加，在 和 之间进一步升高。这与大多数控制变量无关。然而，男性的皮质醇增加趋势高于女性（ = 0.005）。根本未发现sAA反应。然而，sAA水平取决于测量时间点，晚上9点至9点30分之间水平最高。将手浸入冰水中达到最大允许时间3分钟的参与者在所有时间点的sAA水平均高于较早将手从水中移开的参与者。
我们得出结论，当旨在检测皮质醇（但不一定是sAA）反应时，SECPT - G是一种进行急性应激测试的良好方法。
