Abstract

Aim: This study aimed to assess the content, concurrent validity, test-retest, and intra-rater reliability of the Persian version of the Functional Mobility Scale (FMS) for evaluating functional mobility in children and adolescents with cerebral palsy (CP).

Methods: Following international standards for measurement translation, we developed a Persian version of the FMS. A total of 160 participants took part in this study. Concurrent validity was assessed using Spearman's coefficient to correlate with the Gross Motor Function Classification System (GMFCS). Test-retest (n = 30) and intra-rater (n = 30) reliability of the FMS were also examined by Cohen's weighted kappa coefficient.

Results: Concurrent validity ranged from -0.912 to -0.941 for children and -0.912 to -0.936 for adolescents. Test-retest ranged from 0.902 to 1. Intra-rater ranged from 0.933 to 0.987.

Conclusion: The Persian version of the FMS demonstrates very strong validity and almost perfect reliability for assessing and classifying functional mobility in children and adolescents with CP. These findings suggest that this tool could be a useful addition to clinical practice and research for the Persian-speaking population.

波斯语版功能移动量表的心理测量学评估：评估有效性和可靠性

目的：本研究旨在评估波斯语版功能性活动能力量表（FMS）的内容、并发效度、重测效度和评分者内部信度，以评估脑瘫儿童和青少年的功能性活动能力：方法：根据国际测量翻译标准，我们开发了波斯语版的功能移动量表。共有 160 名参与者参与了这项研究。使用斯皮尔曼系数评估了与粗大运动功能分类系统（GMFCS）的相关性。此外，还采用科恩加权卡帕系数（Cohen's weighted kappa coefficient）对 FMS 的测试-重复可靠性（n = 30）和评分者内部可靠性（n = 30）进行了评估：结果：儿童的并发效度为-0.912--0.941，青少年的并发效度为-0.912--0.936。测验重复率为 0.902 至 1，内部重复率为 0.933 至 0.987：波斯语版的FMS在对患有CP的儿童和青少年的功能活动能力进行评估和分类时，表现出了很强的有效性和几乎完美的可靠性。这些研究结果表明，对于波斯语人群来说，该工具可以成为临床实践和研究的有益补充。
