目的
研究计算机化版本的西安大略和麦克马斯特大学（WOMAC）骨关节炎指数的有效性和可行性。
方法
30例膝关节骨关节炎（OA）患者以随机顺序完成了WOMAC的纸质版和计算机版。使用视觉模拟缩放版本的WOMAC，VA3.0。我们通过比较纸质版和计算机版的标准效度进行了研究。
结果
所有患者均完成了计算机版本，没有过度的困难。基于汇总子量表评分的标准效度极佳：疼痛，ICC = 0.89，僵硬，ICC = 0.87，身体功能，ICC = 0.95。
结论
WOMAC VA3.0的计算机版本是纸质版本的有效替代品。
OBJECTIVE
To study the validity and feasibility of a computerized version of the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index.
METHODS
Thirty patients with osteoarthritis (OA) of the knee completed both a paper and a computerized version of WOMAC in random order. The visual analog scaled version of WOMAC, VA3.0, was used. We studied criterion validity by comparing the paper and computerized versions.
RESULTS
All patients completed the computerized version without undue difficulty. Criterion validity, based on aggregated subscale scores, was excellent: Pain, ICC = 0.89, Stiffness, ICC = 0.87, Physical Function, ICC = 0.95.
CONCLUSION
The computerized version of WOMAC VA3.0 is a valid alternative to the paper version.
