To cross-culturally translate the Multiple Sclerosis Spasticity Scale into Italian and to evaluate its psychometric properties in patients with multiple sclerosis.
The Italian version of Multiple Sclerosis Spasticity Scale was developed in accordance with international standards and subsequently administered to 232 Italian adults with multiple sclerosis. The following psychometric properties were analyzed: internal consistency through Cronbach's α and item-to-total correlation, dimensionality with factor analysis, and convergent and criterion validity through hypotheses-testing, comparing the Multiple Sclerosis Spasticity Scale with other outcome measures (Fatigue Severity Scale, Multiple Sclerosis Quality of Life, Modified Ashworth Scale, Barthel Index, and Expanded Disability Status Scale) and analyzing related constructs. Finally, we correlated the MSSS-88 subscales with each other.
The final Multiple Sclerosis Spasticity Scale version was well-understood by all subjects. The internal consistency was good (Cronbach's α ≥0.90). Factor analysis revealed that each subscale was unidimensional. Convergent and criterion validity were supported by acceptable correlations with other disease-specific questionnaires, according to the a priori expectations.
The final Italian Multiple Sclerosis Spasticity Scale version showed robust psychometric properties. Therefore, it can be recommended as an assessment tool for clinical and research use to evaluate spasticity in Italian patients with multiple sclerosis. Implications for rehabilitation The Multiple Sclerosis Spasticity Scale was developed to measure patients' perception of the impact of spasticity on life of subjects with multiple sclerosis. In a sample of Italian subjects with multiple sclerosis, the Multiple Sclerosis Spasticity Scale revealed good internal consistency and convergent and criterion validity. Factor analysis demonstrated that each subscale was unidimensional. Each subscale can be used to assess the impact of spasticity in Italian patients with multiple sclerosis.
将多发性硬化痉挛量表跨文化译为意大利语，并评估其在多发性硬化患者中的心理测量特性。
按照国际标准制定多发性硬化痉挛量表意大利语版本，随后对 232 名意大利多发性硬化症成年人进行测试。分析以下心理测量特性：内部一致性采用 Cronbach's α 和项目与总分的相关性进行评估；维度性采用因子分析进行评估；收敛和标准有效性采用假设检验进行评估，通过比较多发性硬化痉挛量表与其他结果测量（疲劳严重程度量表、多发性硬化生活质量量表、改良 Ashworth 量表、巴氏指数和扩展残疾状态量表）和分析相关结构进行评估。最后，我们对 MSSS-88 子量表进行了相关性分析。
所有受试者都能很好地理解最终的多发性硬化痉挛量表版本。内部一致性良好（Cronbach's α≥0.90）。因子分析表明，每个子量表都是单维的。根据先验预期，与其他疾病特异性问卷的可接受相关性支持了收敛和标准有效性。
最终的意大利多发性硬化痉挛量表版本显示出良好的心理测量特性。因此，它可以推荐作为评估意大利多发性硬化症患者痉挛的临床和研究工具。
多发性硬化痉挛量表的开发是为了衡量多发性硬化症患者对痉挛对生活影响的感知。在一个意大利多发性硬化症受试者样本中，多发性硬化痉挛量表显示出良好的内部一致性、收敛和标准有效性。因子分析表明，每个子量表都是单维的。每个子量表都可以用于评估意大利多发性硬化症患者的痉挛影响。
