Death anxiety plays a significant transdiagnostic role in the development of psychopathology, however there is scarce research examining its relationship with psychosis. We conducted a scoping review to systematically document and describe empirical research on death anxiety and psychosis in clinical populations, to determine the nature and extent of research undertaken, and to identify gaps in the research. We searched six databases using death anxiety and psychosis-specific terms. Searches identified 1222 citations; 28 reports met inclusion criteria. Studies spanned 61 years, conducted across 12 countries. Existing research was limited by lack of experimental methodology, minimal focus on specific symptoms and influential mechanisms, no interventions or treatments, and inadequately theorized conclusions about the relationship between death anxiety and psychosis. Quality future research is needed, with robust experimental designs, a stronger focus on assessing and targeting specific symptoms and mechanisms, and integration of relevant theoretical frameworks.
