This book offers a clinical guide that brings together a broad range of brief interventions and their applications in treating psychosis. It describes two core approaches that can narrow the current, substantial gap between the need for psychotherapeutic interventions for all individuals suffering from psychosis, and the limited mental health resources available. The first approach involves utilizing the standard therapeutic modalities in the context of routine clinical interactions after adapting them into brief and effective formats. To that end, the book brings in experts on various psychotherapeutic modalities, who discuss how their particular modality could be adapted to more effectively fit into the existing system of care delivery. The second approach, addressed in detail, is to extend the availability of these brief interventions by utilizing the circle of providers as well as the social circle of the clients so that these interventions can be provided in a coordinated and complementary manner by psychiatrists, psychologists, clinical social workers, case managers, peer support specialists and other providers on the one hand, and by family members, friends, social and religious institutions on the other.
