In response to the global COVID-19 pandemic, researchers have validated both one-session and two-session online versions of the Trier Social Stress Test (TSST-OL). In a sample of 82 first-generation college students aged 18-25 from across the U.S. (M = 22.30; 75.61 % female; 34.15 % White, 15.85 % Black, 30.49 % Asian, 9.76 % Multiracial, 7.32 % other), we investigated the comparative effectiveness of a one-session and two-session version of the TSST-OL at eliciting a biological stress response. We found no significant differences between the one-session and two-session protocol with respect to cortisol reactivity (i.e., change from baseline to peak, area under the curve with respect to increase, sample peak, and likelihood of demonstrating a response) and self-reported stress during the TSST-OL. The findings indicate that both protocols may be effective at eliciting a stress response. Researchers should consider utilizing a one-session TSST-OL protocol to increase researcher feasibility and make participation more accessible, thereby increasing the representativeness of samples.
为应对全球新冠疫情，研究人员已验证了特里尔社会应激测试（TSST - OL）的单节次和双节次在线版本。在美国各地抽取的82名年龄在18至25岁之间的第一代大学生样本中（平均年龄M = 22.30岁；75.61%为女性；34.15%为白人，15.85%为黑人，30.49%为亚洲人，9.76%为多种族，7.32%为其他种族），我们研究了单节次和双节次版本的TSST - OL在引发生物应激反应方面的相对有效性。我们发现，在TSST - OL期间，单节次和双节次方案在皮质醇反应性（即从基线到峰值的变化、曲线下面积增加量、样本峰值以及出现反应的可能性）和自我报告的应激方面没有显著差异。研究结果表明，两种方案在引发应激反应方面可能都是有效的。研究人员应考虑采用单节次的TSST - OL方案，以提高研究的可行性并使参与更便捷，从而提高样本的代表性。
