The concept of severe and persistent mental illness (SPMI) lacks a consensual definition. Variations in definitions stem above all from different meanings about the constituent features of the concept and how to operationalize them. Our objective was to clarify the concept of SPMI and to explore the level of concept maturity through pragmatic utility (PU) concept analysis. Our findings suggest that SPMI is a partially mature concept that needs further clarification. We argue that the lack of a uniform definition is inherent to the problem: SPMI refers to a patient population rather than a disease entity, and the term has to be useful for different stakeholder purposes. Therefore, while an agreement on the principle three dimensions included in a definition may be possible (diagnosis, disability, and duration), their operationalization will have to be context-dependent and specific for the task at hand.
严重持续性精神疾病（SPMI）的概念缺乏一个共识性的定义。定义的差异首先源于对该概念构成特征及其操作化方式的不同理解。我们的目标是通过实用效用（PU）概念分析来阐明SPMI的概念，并探索其概念成熟度水平。我们的研究结果表明，SPMI是一个需要进一步澄清的部分成熟的概念。我们认为，缺乏统一的定义是该问题的固有特征：SPMI指的是一类患者群体而非一种疾病实体，并且该术语必须适用于不同利益相关者的目的。因此，虽然在定义中包含的三个主要维度上达成一致可能是可行的（诊断、残疾和病程），但其操作化必须依赖于具体情境且针对手头的任务具有特异性。
