Self-rating scales are finding an increasing use in psychiatric work. Not only are they widely used in research, but they provide the clinician with a score indicating the patient's psychiatric state at any one time, and these scores if repeated throughout the duration of treatment may be considered to provide a continuing measure of the severity of the illness, as does a temperature chart in a febrile illness. Most scales could be improved by item analysis, and in this study the Wakefield Self-Assessment of Depression Inventory, with added items, was subjected to statistical analysis. It was found that valid scales could be constructed for the measurement of anxiety and of depression in general psychiatric disorders, as well as scales for the measurement of the severity of endogenous (primary) depression and of anxiety states. In addition, the derivation of a 'diagnostic' score was confirmed in a cross-validation study and may be found of use both in research and in clinical practice.
自评量表在精神科工作中的应用越来越广泛。它们不仅在研究中被广泛使用，而且能为临床医生提供一个分数，表明患者在任何时刻的精神状态。如果在整个治疗过程中重复这些分数，就可以像发热疾病中的体温图表一样，被视为对疾病严重程度的持续衡量。大多数量表通过项目分析都可以得到改进，在本研究中，添加了项目的韦克菲尔德抑郁自评量表接受了统计分析。研究发现，可以构建有效的量表来测量一般精神障碍中的焦虑和抑郁，以及测量内源性（原发性）抑郁和焦虑状态的严重程度。此外，在交叉验证研究中证实了“诊断”分数的推导，其在研究和临床实践中可能都有用处。
