Abstract

Background: Multiple sclerosis (MS) is a potentially disabling disease of the brain and spinal cord. This cross-sectional study aimed to validate the Arabic version of the Multiple Sclerosis Impact Scale-29 (MSIS-29) using Rasch analysis to assess quality of life in Jordanian MS patients.

Method: Rasch analysis was conducted to evaluate the suitability of the model for the present study. Model fit was assessed by computing item/person separation reliability, infit and outfit mean square (MSQ) values, Cronbach's alpha, and the Akaike Information Criterion.

Results: A total of 301 MS patients were enrolled in the study. Significant likelihood ratios for all three scales (MSIS-29-PHYSICAL, MSIS-29-PSYCHOLOGICAL, and MSIS-29-TOTAL) supported the use of a partial credit Rasch model. An issue with disordered thresholds was resolved by collapsing adjacent response categories. Item reliability scores for MSIS-29-PHYS and MSIS-29-PSYCH were 0.95 and 0.89, respectively, while person reliability scores were 0.92 and 0.84, respectively. Infit and outfit MSQ were within the acceptable range for all items on the MSIS-29-PSYCH scale. However, for the MSIS-29-PHYS scale, item MSIS-29_17 exceeded the acceptable range in both infit (1.93) and outfit (1.82) MSQs, and item MSIS-29_20 exceeded the acceptable range in infit (1.81). The Wright map also indicated that most items were considered relatively easy by the respondents, exhibiting various difficulty levels on the latent scale.

Conclusion: The Arabic version of the MSIS-29 is a valid and reliable tool for evaluating quality of life in Jordanian MS patients.

阿拉伯版多发性硬化影响量表（MSIS-29）的验证：一项Rasch分析研究。

背景：多发性硬化症（MS）是一种潜在的脑和脊髓致残疾病。本横断面研究旨在验证阿拉伯版本的多发性硬化症影响量表-29 (MSIS-29)，使用Rasch分析来评估约旦多发性硬化症患者的生活质量。方法：采用Rasch分析法评价模型对本研究的适用性。模型拟合通过计算项目/人分离信度、内嵌和内嵌均方（MSQ）值、Cronbach’s alpha和赤池信息准则来评估。结果：共有301例MS患者入组研究。所有三个量表（MSIS-29-PHYSICAL， MSIS-29-PSYCHOLOGICAL和MSIS-29-TOTAL）的显著似然比支持部分信用Rasch模型的使用。通过折叠相邻的响应类别来解决阈值无序的问题。MSIS-29-PHYS和MSIS-29-PSYCH的项目信度得分分别为0.95和0.89，个人信度得分分别为0.92和0.84。在MSIS-29-PSYCH量表的所有项目中，Infit和outfit的MSQ都在可接受范围内。然而，对于MSIS-29-PHYS量表，项目MSIS-29_17在infit（1.93）和outfit（1.82）的MSQs中都超过了可接受范围，项目MSIS-29_20在infit（1.81）上超过了可接受范围。Wright地图还显示，大多数项目被受访者认为相对容易，在潜在量表上表现出不同的难度水平。结论：阿拉伯语版MSIS-29是评估约旦多发性硬化症患者生活质量的有效和可靠的工具。

期刊介绍： The journal publishes original contributions dealing with psychological aspects of the etiology, diagnosis, and treatment of disorders arising out of dysfunction of the central nervous system. Archives of Clinical Neuropsychology will also consider manuscripts involving the established principles of the profession of neuropsychology: (a) delivery and evaluation of services, (b) ethical and legal issues, and (c) approaches to education and training. Preference will be given to empirical reports and key reviews. Brief research reports, case studies, and commentaries on published articles (not exceeding two printed pages) will also be considered. At the discretion of the editor, rebuttals to commentaries may be invited. Occasional papers of a theoretical nature will be considered.
