PY - 2022 T2 - Maxcy-Rosenau-Last Public Health & Preventive Medicine, 16e AB - Severe mental illness (SMI) is defined as “a mental, behavior, or emotional disorder” diagnosable according to the Diagnostic and Statistical Manual (DSM) that results in significant functional impairment.2,3 A traditional focus for public mental health systems has been to treat SMI, which account for a disproportionate amount of disability among all mental disorders.1 However, public health approaches to treat mental illness have gradually shifted toward progressively earlier identification and treatment strategies, including preventive strategies. Most of these efforts have been on SMIs such as bipolar disorder and psychotic disorders (including schizophrenia); accordingly, this review focuses on these disorders.
