A growth mindset intervention to improve mental health in adolescents during COVID‐19

Abstract COVID‐19 poses a considerable threat to adolescent mental health. We investigated depression rates in teens from pre to post‐COVID. We also explored if leveraging a growth mindset intervention (“Healthy Minds”) could improve adolescent mental health outcomes during the pandemic, especially for adolescents experiencing the most distress. In Study 1, we recruited youth from schools in a rural southern community ( N = 239) and used a pre‐post design. In Study 2, we recruited an online sample ( N = 833) and used a longitudinal randomized control trial design to test the effectiveness of Healthy Minds. Across both studies, there is evidence of higher rates of depression in youth during COVID‐19, relative to pre‐pandemic numbers. In Study 1, the intervention effectively changed psychological and behavioral processes related to mental health, especially for adolescents experiencing greater COVID‐19 stress. However, in Study 2, the intervention failed to impact depression rates or symptoms at follow‐up.
