The COVID-19 pandemic has enhanced our focus on mental health. Concerns about the high levels of mental disorders in the United States are not new, with rising trends–particularly among youth–observed prior to the pandemic. However, the pandemic may have exacerbated and accelerated these trends. The silver lining is that we can leverage this moment to reevaluate and reimagine not only how we treat mental health problems, but also how we promote emotional well-being throughout the life course. We argue that scholars, policymakers, and practitioners should broaden their view of mental health, and consider it as a full spectrum ranging from serious mental illness to robust emotional well-being. This perspective recognizes the importance of treatment access and quality, but also elevates the value of prevention, particularly at the population level. Greater attention to preventing problems before they occur will not only reduce manifest disorders but also encourage higher rates of psychological resilience and, ultimately, better physical health.
