Vulnerability, Stress, and Support in the Disease Trajectory from Prodrome to Diagnosed Schizophrenia: Diathesis-Stress-Support Model

Abstract

Schizophrenia is a debilitating psychiatric disorder seen across the world. The goal of current research is to provide a more comprehensive understanding of prodrome, the initial period before the disease manifests as schizophrenia. Unfortunately, there is little information to comprehensively understand the indicators that later lead to schizophrenia. This has resulted in a lack of scientific knowledge to aid in early identification and intervention by psychiatric nurses or school nurses. Such information could inform nursing assessment and care plan development. The purpose of this paper is to construct a conceptual model for describing the important factors relating to the schizophrenia prodrome process in human developmental manner by critically synthesizing empirical evidence and reviewing the strengths and limitations of current conceptual models.
