Psychosis Risk: What Is It and How Should We Talk About It?

Schizophrenia and other psychosis spectrum disorders do not develop de novo but emerge from prodromal stages that are named and operationalized differently depending on the research group or consortium and its theoretical orientation. As a result, a complex lexicon now exists for characterizing individuals' risk of subclinical symptoms converting to psychosis. Researchers aim to develop instruments and methods to identify people at risk of psychosis, better understand their risks, and offer preventative treatments to arrest conversion to psychosis; ethical and policy questions loom large with each of these projects. In this paper, we canvass the lexical complexities of the at-risk status for psychosis and then consider ethical and policy challenges that researchers and clinicians face in disclosing, preventing, and treating psychosis risk.
