Study Summary

In this study, the investigators will test the effectiveness of a digital, single-session mental health intervention. There will be two conditions: the COMET intervention and the control group. The program, COMET (Common Elements Toolbox), will include a variety of modules which will focus on cognitive restructuring, gratitude, behavioral activation, and self-compassion. A similar intervention has previously been tested with Indian adolescents and adapted for US graduate students.
