The Multiple Sclerosis Work Difficulties Questionnaire (MSWDQ) is a recently developed, internally consistent and valid 50-item measure of self-reported workplace difficulties in pwMS.
In this study, the second-order factor structure of the MSWDQ was assessed, with the aim of developing a short version of the scale.
Cross-sectional MSWDQ data were obtained along with employment and MS disease information, in a community-based sample of 189 pwMS. Final items for the shortened version were selected to ensure both item breadth and adequacy of psychometric properties.
Confirmatory Factor Analysis on the 12 MSWDQ factors yielded a model comprised of three second-order factors termed physical barriers, psychological/cognitive barriers and external barriers, which formed the basis of the shorter 23-item scale, the MSWDQ-23. The MSWDQ-23 showed excellent subscale internal consistencies. It explained 29% of the variance in reduced work hours since diagnosis, 22% of the variance in expectations of withdrawing from work, 24% of the variance in expectations of reduced work hours and 32% of the variance in expectations of changing type of work due to MS.
The MSWDQ-23 is a brief valid and internally consistent measure of workplace difficulties that can predict both employment outcomes and expectations in pwMS. It is an especially useful tool for clinicians who wish to quickly obtain an indication of the extent of psychological/cognitive, physical and/or external difficulties experienced by individual pwMS in the workplace. Implications for Rehabilitation The MSWDQ-23 is a shortened self-report survey that examines work difficulties in people with MS across three broad domains: psychological/cognitive barriers, physical barriers and external barriers. The MSWDQ-23 is a valid and reliable measure that is capable of predicting various employment outcomes and expectations.
多发性硬化症工作困难问卷（MSWDQ）是最近开发的一种由50个项目组成的、内部一致且有效的工具，用于自我报告多发性硬化症患者在工作场所遇到的困难。
在本研究中，对MSWDQ的二阶因子结构进行评估，旨在开发该量表的简短版本。
在一个基于社区的189名多发性硬化症患者样本中，获取了MSWDQ的横断面数据以及就业和MS疾病信息。选择缩短版的最终项目以确保项目广度和心理测量特性的充分性。
对MSWDQ的12个因子进行验证性因子分析，得出一个由三个二阶因子组成的模型，分别称为身体障碍、心理/认知障碍和外部障碍，这构成了较短的23项量表MSWDQ-23的基础。MSWDQ-23显示出优异的子量表内部一致性。它解释了自诊断以来工作时间减少方差的29%、退出工作期望方差的22%、工作时间减少期望方差的24%以及因MS导致工作类型改变期望方差的32%。
MSWDQ-23是一种简短、有效且内部一致的工作场所困难测量工具，可预测多发性硬化症患者的就业结果和期望。对于希望快速了解个体多发性硬化症患者在工作场所经历的心理/认知、身体和/或外部困难程度的临床医生来说，它是一个特别有用的工具。康复意义：MSWDQ-23是一项缩短的自我报告调查，从心理/认知障碍、身体障碍和外部障碍这三个广泛领域检查多发性硬化症患者的工作困难。MSWDQ-23是一种有效且可靠的测量工具，能够预测各种就业结果和期望。
