The purpose of this study was to determine agreement between responses on electronic and paper versions of the WOMAC and SF-12(v2) questionnaires following total hip and total knee arthroplasty. Patients completed both electronic and paper questionnaires with a one week interval in-between. The order in which they completed the two versions was randomly assigned. A total of 53 patients completed the study, with a mean age of 69 years (range 50-90 years). The intraclass correlation coefficients (ICC) were high, indicating excellent agreement (WOMAC ICC = 0.96, 95% CI 0.94-0.98), SF-12 (PCS) ICC = 0.95, 95% CI 0.92-0.97; SF-12 (MCS) ICC = 0.92, 95%CI 0.86-0.95). Online data collection may be substituted for the traditional paper method with no significant effect on the criterion validity of the questionnaires.
本研究旨在确定全髋关节和全膝关节置换术后 WOMAC 和 SF-12（v2）问卷的电子和纸质版本的回答之间的一致性。患者在一周的时间内分别完成了电子和纸质问卷，完成的顺序是随机分配的。共有 53 名患者完成了研究，平均年龄为 69 岁（范围为 50-90 岁）。组内相关系数（ICC）很高，表明具有极好的一致性（WOMAC ICC = 0.96，95%CI 0.94-0.98），SF-12（PCS）ICC = 0.95，95%CI 0.92-0.97；SF-12（MCS）ICC = 0.92，95%CI 0.86-0.95）。在线数据收集可以替代传统的纸质方法，而不会对问卷的标准效度产生重大影响。
