A well-designed self-reported scale is highly applicable to current clinical and research practices. However, the problems with the scale method, such as quantitative analysis of content validity and test-retest reliability analysis of state-like variables are yet to be resolved. The main purpose of this paper is to propose an operational method for solving these problems. Additionally, it aims to enhance understanding of the research paradigm for the scale method (excluding criterion-related validity). This paper used a study that involved screening of high-risk groups for OCD (Obsessive-Compulsive Disorder), conducted 5 rounds of tests, and developed scales, reliability, and validity analysis (using sample sizes of 496, 610, 600, 600 and 990). The operational method we propose is practical, feasible, and can be used to develop and validate a scale.
设计良好的自陈式量表非常适用于当前的临床和研究实践。然而，量表方法存在一些问题，例如状态变量的内容效度的定量分析和重测信度分析尚未得到解决。本文的主要目的是提出一种解决这些问题的操作方法。此外，还旨在增强对量表方法（不包括效标关联效度）研究范式的理解。本文使用了一项涉及强迫症（OCD）高危人群筛查的研究，进行了 5 轮测试，并开发了量表、可靠性和有效性分析（使用样本量为 496、610、600、600 和 990）。我们提出的操作方法实用、可行，可用于开发和验证量表。
