The Emotional Processing Scale (EPS) is a 38-item, eight-factor self-report questionnaire designed to measure emotional processing styles and deficits. Scale development is an ongoing process and our aim was to (i) refine the scale by trying out items from a new item pool and (ii) shorten the scale to enhance its clinical and research utility.
Fifteen new items were added to the original 38-item pool. The resulting 53-item scale was administered to four groups (N=690) (mental health, healthy controls, pain patients, and general medical practice attendees). Exploratory factor analysis was used to explore the underlying factor structure.
Maximum likelihood (ML) factor analysis was used to guide the process of item selection and scale reduction. Four of the previous eight factors remained in similar form, two of the original factors were discarded, and one new factor emerged incorporating items from two previous factors. The revised version of the scale (EPS-25) has a 25-item five-factor structure. Internal reliability was moderate to high for all five factors.
The psychometric properties of the revised scale appear promising, particularly in relation to the detection of differences between diagnostic groups.
情感处理量表（EPS）是一个 38 项、八因素的自我报告问卷，旨在测量情感处理方式和缺陷。量表的开发是一个持续的过程，我们的目的是（i）通过尝试新的项目池中的项目来改进量表，（ii）缩短量表以增强其临床和研究实用性。
在原始的 38 项量表中增加了 15 项新的项目。对四组（N=690）（心理健康、健康对照组、疼痛患者和普通医疗实践参与者）进行了 53 项量表的测试。采用探索性因子分析来探索潜在的因子结构。
最大似然（ML）因子分析用于指导项目选择和量表缩减的过程。之前的八个因素中的四个保持相似的形式，两个原始因素被丢弃，一个新的因素出现，将两个之前的因素的项目合并在一起。修订后的量表（EPS-25）具有 25 项五因素结构。所有五个因素的内部信度都在中等至高水平。
修订后的量表的心理测量特性似乎很有前途，特别是在检测诊断组之间的差异方面。
