Serious mental illness-Psychology's call to action: If not us, who? If not now, when?

While psychology has much to contribute to the care of individuals living with a serious mental illness (SMI), psychologists have been and continue to be underrepresented as their treatment providers. However, serving those living with an SMI presents an urgent public health need. In this article, we provide an overview of the historical role of psychology in the care of individuals with SMIs, and we argue that a confluence of factors renders this a propitious time for psychologists to increase their commitment to the care of those living with an SMI. These factors include (a) the availability of strengths-based and/or functional assessment tools and effective psychosocial interventions, often created or empirically tested and enhanced by psychologists, (b) the continuing evolution of a recovery movement which brings more optimism to the field, and (c) the establishment, over the past 15 years, of an APA recognized and approved infrastructure to provide and recognize formal SMI Psychology training and expertise.
