Randomized controlled trials assessing efficacy of brief web-based stress management interventions for college students during the COVID pandemic.

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 ( = 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 s = -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).
