Abstract
Aims: This study aims to evaluate the reliability and validity of the Community Balance and Mobility Scale (CB&M) in people with multiple sclerosis (PwMS).
Methods: A total of 65 PwMS (Expanded Disability Status Scale (EDSS) ≤ 5.5) were included in the study. Test-retest, internal consistency (item-total score correlation, Cronbach's alpha coefficient) intra-rater, and inter-rater reliability were investigated for the reliability of the CB&M. For intra-rater and inter-rater reliability, CB&M measurements of 34 PwMS were videotaped. The validity of the CB&M was assessed through criterion (predictive and concurrent validity) and construct validity. Construct validity was evaluated using hypothesis testing which included examining correlations with EDSS, Timed Up and Go Test (TUG), and Dynamic Gait Index (DGI).
Results: Test-retest reliability demonstrated a good to excellent correlation (ICC = 0.995, p < 0.001). Cronbach's alpha was 0.971 (p < 0.001). Intra-rater (ICC = 0.993, p < 0.001) and inter-rater reliability (ICC = 0.986, p < 0.001) of the CB&M were also good to excellent. Cohen's kappa range values of the scale vary between 0.958 - 0.665, and the percentage agreement varies between 97% and 75%. For the convergent validity of CB&M, strong correlations were observed with EDSS (r=-0.831, p < 0.001), TUG (r=-0.854, p < 0.001), and DGI (r = 0.865, p < 0.001). Additionally, the CB&M demonstrated an excellent correlation with the BBS (r = 0.907, p < 0.001). The scale exhibited no floor-ceiling effect.
Conclusion: CB&M is a reliable and valid tool for assessing balance and mobility in PwMS and offers significant advantages for evaluating balance in PwMS, as it provides comprehensive information about the balance and mobility requirements essential for community living.
目的:本研究旨在评估社区平衡与活动量表(CB&M)在多发性硬化症(PwMS)患者中的信度和效度。方法:选取65例扩展残疾状态量表(EDSS)≤5.5的患者作为研究对象。对CB&M的信度进行重测、内部一致性(项目总分相关性、Cronbach’s alpha系数)、评分者内信度和评分者间信度的研究。为了提高内部和内部的可靠性,对34台PwMS的CB&M测量进行了录像。通过预测效度、并发效度和构念效度来评估CB&M的效度。建构效度评估采用假设检验,包括检验EDSS、Timed Up and Go Test (TUG)和动态步态指数(DGI)的相关性。结果:重测信度呈良好至极好的相关性(ICC = 0.995, p)。结论:CB&M是一种可靠有效的评估PwMS平衡性和流动性的工具,它提供了社区生活所需的平衡和流动性需求的全面信息,在评估PwMS平衡性方面具有显著优势。
