Digital Mental Health and Wellness Intervention for Adults: A Randomized Control Trial of COMET

The investigators are evaluating the acceptability and effectiveness of brief online wellness modules. Participants will be randomly assigned to the intervention condition, an active control condition, or a wait-list control condition. The investigators are using a factorial design, such that each participant in the intervention condition will be randomly assigned to receive three of four wellness modules. The investigators will analyze the intervention's effectiveness as a universal intervention (using the full sample) and a targeted intervention (using the subset of the sample that reported elevated depressive symptoms or anxiety symptoms at baseline).
