To assesses the reliability and validity of the Bengali version of the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0, 36-item) for individuals with spinal cord injury (SCI).
A total of 144 participants (81% men) completed the WHODAS 2.0, the Spinal Cord Independence Measure (SCIM), and the SF-36 Health Survey, alongside socio-demographic and injury-related data. A sub-sample of 62 was reassessed after 8-10 days. Reliability was evaluated using Cronbach's alpha and intra-class correlation coefficients (ICC). Validity was examined through internal structure, convergent validity ( correlations with SCIM and SF-36), discriminant validity (by comparing groups with tetraplegia and paraplegia), and Rasch analysis.
Internal consistency ranged from questionable (α = 0.69 for getting around) to excellent (α = 0.92 for life activities). Test-retest reliability ranged from moderate (ICC = 0.58 for cognition) to excellent (ICC = 0.92 for self-care). Significant correlations with SCIM and SF-36 supported convergent validity, while group differences based on neurological level supported discriminant validity. All items in the Cognition domain failed to fit the Rasch model.
The Bengali WHODAS 2.0 demonstrates acceptable reliability and validity for individuals with SCI, supporting its clinical use in resource-limited settings. Further validation in larger samples is recommended, particularly for the Cognition domain.
评估世界卫生组织残疾评定量表2.0（WHODAS 2.0，36项）孟加拉语版本对脊髓损伤（SCI）患者的可靠性和有效性。
共有144名参与者（81%为男性）完成了WHODAS 2.0、脊髓独立测量量表（SCIM）和SF - 36健康调查，同时收集了社会人口统计学和损伤相关数据。62名参与者的子样本在8 - 10天后进行了重新评估。使用克朗巴哈系数（Cronbach's alpha）和组内相关系数（ICC）评估可靠性。通过内部结构、收敛效度（与SCIM和SF - 36的相关性）、区分效度（比较四肢瘫和截瘫组）以及拉施分析来检验效度。
内部一致性从可疑（“四处活动”方面α = 0.69）到优秀（“生活活动”方面α = 0.92）不等。重测信度从中度（“认知”方面ICC = 0.58）到优秀（“自我护理”方面ICC = 0.92）不等。与SCIM和SF - 36的显著相关性支持了收敛效度，而基于神经损伤水平的组间差异支持了区分效度。认知领域的所有项目均不符合拉施模型。
孟加拉语版WHODAS 2.0对SCI患者显示出可接受的可靠性和有效性，支持其在资源有限环境中的临床应用。建议在更大样本中进一步验证，特别是对于认知领域。
