背景：疼痛灾变量表（PCS）是一种常用的疼痛灾变量表。该量表包括13个项目，涉及放大、反刍和无助。为方便快速筛选及减轻参加者的负担，本署编制了四项及六项简体英文本。本研究的目的是利用一种称为Rasch分析的当代方法来评估日本版PCS简短形式的心理测量特性。方法：本研究共招募216例肌肉骨骼疾病患者。参与者完成了研究测量，包括疼痛强度、疼痛灾难量表（PCS）和坦帕运动恐惧症量表（TSK）。此外，还测量了日语版PCS的四项（第3、6、8、11项）和六项（第4、5、6、10、11、13项）简短形式。我们使用Rasch分析来分析原始、四项和六项PCS简短表格的心理测量特性。结果：Rasch分析显示，两种简短形式的PCS具有可接受的内部一致性和单维性，没有显著的DIF，在类别评定量表上具有功能。然而，四项短形式的PCS有两个不合适的项目。结论：六项简短形式的PCS具有可接受的心理测量特性，适合用于肌肉骨骼疼痛的参与者。因此，六个项目可以作为评估疼痛灾难化的简单工具。(C) 2016日本骨科协会。Elsevier b.v.版权所有。
Background: The Pain Catastrophizing Scale (PCS) is a commonly used as measure of pain catastrophizing. The scale comprises 13 items related to magnification, rumination, and helplessness. To facilitate quick screening and to reduce participant's burden, the four-item and six-item short forms of the English version of the PCS were developed. The purpose of the present study was to evaluate the psychometric properties of a Japanese version of the short forms of PCS using a contemporary approach called Rasch analysis.Methods: A total of 216 patients with musculoskeletal disorders were recruited in this study. Participants completed study measures, which included the pain intensity, the Pain Catastrophizing Scale (PCS), and the Tampa Scale of Kinesiophobia (TSK). Furthermore, the four-item (items 3, 6, 8, and 11) and six-item (items 4, 5, 6, 10, 11, and 13) short forms of the Japanese version of PCS were measured. We used Rasch analysis to analyze the psychometric properties of the original, four-item, and six-item short forms of PCS.Results: Rasch analysis showed that both short forms of PCS had acceptable internal consistency, unidimensionality, and no notable DIF and were functional on the category rating scale. However, fouritem short form of PCS had two misfit items.Conclusions: Six-item short form of PCS has acceptable psychometric properties and is suitable for use in participants with musculoskeletal pain. Thus, six-item can be used as brief instruments to evaluate pain catastrophizing. (C) 2016 The Japanese Orthopaedic Association. Published by Elsevier B. V. All rights reserved.
