The purpose of this study was to check the reliability and validity of the 12-item Chinese version of the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) for the assessment of disability in patients with Kashin-Beck disease (KBD). We recruited 219 patients with KBD from the high-risk KBD area in the Shaanxi province, using stratified multistage random sampling. We assessed each patient using the Chinese version of the 12-item WHODAS 2.0 and the Western Ontario and McMaster Universities Index of Osteoarthritis (WOMAC). Statistical evaluations of the instruments consisted of Cronbach's alpha, intraclass correlation coefficient (ICC), confirmatory factor analysis (CFA), and Pearson's correlation coefficient. Cronbach's alpha and ICC for the six domains ranged from 0.704 to 0.906 and 0.690 to 0.852, respectively. A six-factor structure fits the data well (CFI = 0.967, TLI = 0.944, RMSEA = 0.08). Regarding convergent validity, the four domains of the 12-item WHODAS 2.0 (getting around, self-care, life activity, and participation) showed moderate-to-strong correlation for all three domains of the WOMAC (0.428 < |r| < 0.804). Regarding divergent validity, the two domains of the 12-item WHODAS 2.0 (understanding and communication, and getting along with people) showed weak correlation for the three domains of WOMAC (0.182 < |r| < 0.295). The Chinese version of 12-item WHODAS 2.0 questionnaire is a reliable and valid instrument when administered to KBD patients.
本研究旨在检验 12 项中文版世界卫生组织残疾评定量表 2.0（WHODAS 2.0）用于评估大骨节病（KBD）患者残疾的信度和效度。我们采用分层多阶段随机抽样的方法，从陕西省高危大骨节病地区招募了 219 例 KBD 患者。采用中文版 WHODAS 2.0 和西部安大略省和麦克马斯特大学骨关节炎指数（WOMAC）对每位患者进行评估。对这些工具的统计评估包括 Cronbach's alpha、组内相关系数（ICC）、验证性因子分析（CFA）和 Pearson 相关系数。六个领域的 Cronbach's alpha 和 ICC 分别为 0.704 至 0.906 和 0.690 至 0.852。六因素结构拟合数据较好（CFI=0.967，TLI=0.944，RMSEA=0.08）。关于聚合效度，WHODAS 2.0 的四个领域（走动、自理、生活活动和参与）与 WOMAC 的三个领域（0.428<|r|<0.804）之间呈中到高度相关。关于发散效度，WHODAS 2.0 的两个领域（理解和交流以及与人相处）与 WOMAC 的三个领域（0.182<|r|<0.295）之间呈弱相关。中文版 12 项 WHODAS 2.0 问卷是一种可靠和有效的工具，可用于评估 KBD 患者。
