ABSTRACT
Social-evaluative stressors-experiences in which people feel they could be judged negatively-pose a major threat to adolescent mental health1-3 and can cause young people to disengage from stressful pursuits, resulting in missed opportunities to acquire valuable skills. Here we show that replicable benefits for the stress responses of adolescents can be achieved with a short (around 30-min), scalable 'synergistic mindsets' intervention. This intervention, which is a self-administered online training module, synergistically targets both growth mindsets4 (the idea that intelligence can be developed) and stress-can-be-enhancing mindsets5 (the idea that one's physiological stress response can fuel optimal performance). In six double-blind, randomized, controlled experiments that were conducted with secondary and post-secondary students in the United States, the synergistic mindsets intervention improved stress-related cognitions (study 1, n = 2,717; study 2, n = 755), cardiovascular reactivity (study 3, n = 160; study 4, n = 200), daily cortisol levels (study 5, n = 118 students, n = 1,213 observations), psychological well-being (studies 4 and 5), academic success (study 5) and anxiety symptoms during the 2020 COVID-19 lockdowns (study 6, n = 341). Heterogeneity analyses (studies 3, 5 and 6) and a four-cell experiment (study 4) showed that the benefits of the intervention depended on addressing both mindsets-growth and stress-synergistically. Confidence in these conclusions comes from a conservative, Bayesian machine-learning statistical method for detecting heterogeneous effects6. Thus, our research has identified a treatment for adolescent stress that could, in principle, be scaled nationally at low cost.

This research examined the effects of the onset of the COVID-19 pandemic on perceived Black-White intergroup competition and negative intergroup psychological outcomes. Two datasets (collected before [2018] and after the onset of [April, 2020] COVID-19) were combined (N = 2,131) for this research. The data provided support for the hypothesis that perceptions of Black-White intergroup competition, and subsequently perceptions of discrimination, behavioral avoidance, intergroup anxiety, and interracial mistrust would be higher after the onset of COVID-19. Three additional predictors, a perceived interracial competition manipulation, political orientation, and population density at the ZIP-code level were examined to test for main effects and moderation of COVID-19 effects. All three predictors exhibited main effects on focal outcomes, and political orientation moderated COVID-19 onset effects: effects were stronger for conservatives. Lastly, perceived intergroup competition mediated the effect of COVID-19 onset on the four focal outcomes.
