Evaluating an Online Wellness Intervention for Greek Adolescents

Evaluating an Online Single-session Intervention for Mental Health and Wellness of Greek Adolescents

The investigators are evaluating the effects of an online single-session mental health intervention (the Common Elements Toolbox; COMET). To evaluate COMET, the investigators are conducting a randomized controlled trial with Greek adolescents attending high school in the Attica region in Greece. Students will be randomized to the COMET condition or to an active control condition. Primary outcome measures (depressive symptoms, anxiety symptoms, subjective well-being) will be measured at two weeks post-intervention, four weeks post-intervention, and eight weeks post-intervention. The investigators will evaluate COMET as a universal intervention (using the full sample) and as a targeted intervention (analyzing those who reported elevated depressive symptoms or anxiety symptoms at baseline).
