This article reviews and discusses the literature on the recognition of the early warning signs of psychosis. The assumption is that nurses, in the everyday exercise of their profession, can contribute to the prevention of psychotic relapse in schizophrenic patients by the early recognition of warning signs. First, the process of psychotic relapse and the factors that influence it are described. Then research on the early signs of psychosis is discussed. This article questions the most common early signs, when they occur, and who can recognize them. Then the predictive value of the early signs is considered: how well can psychotic relapse be predicted with these early signs? Finally, the research on the effects of early recognition and early intervention is discussed, primarily with respect to the question of whether psychotic relapses can actually be prevented by making use of preventive intervention strategies. The conclusion is that the preliminary results are hopeful and invite further research on such matters as the application of this intervention strategy within nursing practice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
