The Multiple Sclerosis Self-Management scale (MSSM) was developed to provide a multidimensional and psychometrically sound assessment of self-management knowledge and behavior among adults with multiple sclerosis (MS). This article describes recent revisions to the scale and presents the results of subsequent analyses of the factor structure and psychometric adequacy of the revised MSSM.
Participants were 197 adults with MS randomly selected from mailing lists of 3 chapters of the National Multiple Sclerosis Society. Participants completed mailed questionnaires including the MSSM and several additional instruments measuring constructs associated with self-management.
Factor analysis of the revised MSSM revealed 5 psychometrically sound factors. Construct validity was supported by factor analysis and correlation of the MSSM with constructs related to self-management. Specifically, the MSSM was significantly positively correlated with MS self-efficacy and quality of life ratings, and significantly negatively correlated with psychological and physical impact of MS, as measured with the Multiple Sclerosis Impact Scale. Internal consistency reliability for the scale was acceptable (α = .85).
The MSSM, as revised, is a brief, psychometrically sound, and multidimensional self-management scale for research and clinical applications.
多发性硬化症自我管理量表（MSSM）旨在为多发性硬化症（MS）成人提供多维和心理测量健全的自我管理知识和行为评估。本文描述了该量表的最新修订，并介绍了随后对修订后的 MSSM 进行的因子结构和心理测量充分性分析的结果。
参与者是从国家多发性硬化症协会的 3 个分会的邮寄名单中随机选择的 197 名成年人多发性硬化症患者。参与者完成了邮寄问卷，包括 MSSM 和几个衡量与自我管理相关的结构的其他工具。
修订后的 MSSM 的因子分析显示出 5 个心理测量健全的因素。通过因子分析和 MSSM 与与自我管理相关的结构的相关性来支持构念效度。具体而言，MSSM 与多发性硬化症自我效能和生活质量评分呈显著正相关，与多发性硬化症的心理和身体影响呈显著负相关，这是用多发性硬化症影响量表测量的。该量表的内部一致性信度可接受（α=0.85）。
修订后的 MSSM 是一种简短、心理测量健全且多维的自我管理量表，可用于研究和临床应用。
