To compare data based on touch screen to data based on traditional paper versions of questionnaires frequently used to examine patient reported outcomes in knee osteoarthritis patients and to examine the impact of patient characteristics on this comparison
Participants were recruited from an ongoing trial (http://ClinicalTrials.Gov Identifier: NCT00655941). 20 female participants, mean age 67 (SD 7), completed KOOS, VAS pain, function and patient global, SF-36, Physical Activity Scale, painDETECT, and the ADL Taxonomy. Patients were randomly assigned to one of two subgroups, completing either the paper or touch screen version first. Mean, mean differences (95% CI), median, median differences and Intraclass Correlation Coefficients (ICCs) were calculated for all questionnaires.
ICCs between data based on computerized and paper versions ranged from 0.86 to 0.99. Analysis revealed a statistically significant difference between versions of the ADL Taxonomy, but not for the remaining questionnaires. Age, computer experience or education-level had no significant impact on the results. The computerized questionnaires were reported to be easier to use.
The computerized questionnaires gave comparable results to answers given on paper. Patient characteristics did not influence results and implementation was feasible.
为了比较基于触摸屏的与传统纸质问卷的患者报告膝关节骨关节炎结局数据，并探究患者特征对此比较的影响。
参与者从一项正在进行的试验中招募而来（http://ClinicalTrials.Gov Identifier: NCT00655941）。20 名女性参与者，平均年龄 67 岁（标准差 7），完成 KOOS、VAS 疼痛、功能和患者整体评分、SF-36、体力活动量表、疼痛 DETECT 和日常生活活动分类。患者被随机分配到两个亚组之一，首先完成纸质版或触屏版问卷。所有问卷均计算了平均值、平均值差异（95%置信区间）、中位数、中位数差异和组内相关系数（ICC）。
基于计算机和纸质版本的数据之间的 ICC 范围从 0.86 到 0.99。分析显示日常生活活动分类的两种版本之间存在统计学差异，但其余问卷则无此差异。年龄、计算机使用经验或教育程度对结果无显著影响。触屏版问卷更易于使用。
计算机版问卷得出的结果与纸质问卷的结果相当。患者特征对结果无影响，且实施是可行的。
