The purpose of this study was to evaluate the efficacy of brief, self-guided web-based interventions for decreasing distress among U.S. college students during the pandemic. Three randomized controlled trials were conducted during the spring (Study 1), summer (Study 2), and fall (Study 3) 2020 terms, and were combined into one sample to increase power (N = 775). We evaluated a web-based intervention that focused on increasing present control that had been shown to be effective in several studies prior to the pandemic (e.g., Nguyen-Feng et al., 2017). This intervention was compared to an active comparison condition (psychoeducation about and reminders to engage in Centers for Disease Control and Prevention (CDC)-recommended stress management techniques) in Study 1, to a waitlist comparison in Study 2, and to both comparison conditions in Study 3. Participants were undergraduate psychology students at two campuses of a midwestern state university system. Outcomes-perceived stress (primary); depression, anxiety, and stress symptoms (secondary); and boredom (tertiary)-were assessed at pretest and posttest (and 3-week follow-up in Study 3). Differences across conditions were significant for perceived stress, stress symptoms, and boredom (but not depression or anxiety). Contrary to hypotheses, the Present Control and CDC stress management interventions were equally effective. Both were more effective than no intervention (between-group ds = -0.27 and -0.42). Both interventions were more effective for students with higher baseline stress levels. Completion and adherence rates were high for both conditions. Results suggest that very brief, self-guided stress management interventions can be effective in reducing stress among college students. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

评估 COVID 大流行期间基于网络的简短压力管理干预措施对大学生的疗效的随机对照试验。

本研究的目的是评估简短的、基于网络的自我指导干预措施在大流行期间减少美国大学生痛苦的效果。在 2020 年春季（研究 1）、夏季（研究 2）和秋季（研究 3）期间进行了三项随机对照试验，并将其合并为一个样本以增加功效（N = 775）。我们评估了一种基于网络的干预措施，该干预措施侧重于增加目前的控制，这种干预在大流行之前的几项研究中被证明是有效的（例如，Nguyen-Feng 等人，2017 年）。将这种干预与研究 1 中的主动比较条件（关于参与疾病控制和预防中心 (CDC) 推荐的压力管理技术的心理教育和提醒）、研究 2 中的候补名单比较以及研究中的两种比较条件进行了比较研究 3。参与者是中西部州立大学系统两个校区的本科心理学学生。结果感知压力（主要）；抑郁、焦虑和压力症状（次要）；和无聊（第三级）——在前测和后测（以及研究 3 中的 3 周随访）中进行评估。不同条件下的差异对于感知压力、压力症状和无聊（但不是抑郁或焦虑）是显着的。与假设相反，Present Control 和 CDC 压力管理干预措施同样有效。两者都比没有干预更有效（组间 ds = -0.27 和 -0.42）。这两种干预措施对基线压力水平较高的学生更有效。两种情况的完成率和依从率都很高。结果表明非常简短，自我引导的压力管理干预可以有效减轻大学生的压力。（PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
