本文以贵州师范大学共90个大一新生在症状自评量表上的数据为实例,讨论Rasch等级模型在设计和修订等级量表中的应用,以及如何应用Rasch等级模型的某些参数如选项频率、平均测量值、临界值、概率曲线、选项拟合指数等来对等级量表的选项分类数目、选项标签进行直观的分析和检验,从而获得高质量量表。实例分析结果显示量表的各项指标均符合Rasch等级模型的规定,数据对模型的拟合非常好。

In this article SCL-90 （Chinese version） was used to illustrate how to use Rasch model to analyze rating scale. In the Rasch analysis, a useful method to obtain diagnostics in evaluating category usage is to examine the average measures and threshold of each category, probability curves of each item and the item fit mean squares （MNSQ）. The number and the lables of categories of response choices were empirically analyzed and the results indicated that SCL-90 satisfied most important theoretical merits of Rasch model including the two MNSQ statistics widely used infit（weighted） and outfit （unweighted）.
