背景资料：在临床实践和研究中越来越多地使用自我报告的健康状况，以及患者对监测健康随时间的波动的赞赏，表明需要更频繁地收集数据。电子使用健康状况的措施，在后续的病人是一种可能的方式来实现这一点。目的：比较自我报告的健康状况的措施，在个人数字助理（PDA）版本和纸/笔版本的测试-重测信度，分数之间的协议，和可行性。方法：30例稳定型类风湿性关节炎患者（平均年龄61.6岁，范围49.8 - 70.0岁;平均病程16.7年; 63%女性; 67%类风湿因子阳性; 46.6%的患者使用缓解疾病的抗风湿药物）完成了自我报告的健康状况测量（疼痛、疲劳和视觉模拟量表（VAS）的总体健康，类风湿性关节炎疾病活动指数，改良的健康评估问卷，SF-36），并在PDA（HP iPAQ，型号h5450）上进行。完成后重复5至7 day.Results：重测信度是相似的，由Bland-Altman方法，变异系数和组内相关系数进行评估。评分显示出可接受的一致性，但PDA的VAS评分略高于纸/笔版本。没有显着差异被认为是可行性措施（时间完成，满意度评分），但65.5%首选PDA，20.7%首选纸张，13.8%没有preference.Conclusions：临床表现的纸/铅笔版本的自我报告的健康状况措施是类似的电子版本，使用廉价的PDA。
Background: Increasing use of self reported health status in clinical practice and research, as well as patient appreciation of monitoring fluctuations of health over time, suggest a need for more frequent collection of data. Electronic use of health status measures in the follow up of patients is a possible way to achieve this.Objective: To compare self reported health status measures in a personal digital assistant (PDA) version and a paper/pencil version for test - retest reliability, agreement between scores, and feasibility.Methods: 30 patients with stable rheumatoid arthritis ( mean age 61.6 years, range 49.8 to 70.0; mean disease duration, 16.7 years; 63% female; 67% rheumatoid factor positive; 46.6% on disease modifying antirheumatic drugs) completed self reported health status measures ( pain, fatigue, and global health on visual analogue scales ( VAS), rheumatoid arthritis disease activity index, modified health assessment questionnaire, SF-36) in a conventional paper based questionnaire version and on a PDA ( HP iPAQ, model h5450). Completion was repeated after five to seven days.Results: Test - retest reliability was similar, as evaluated by the Bland - Altman approach, the coefficient of variation, and intraclass correlation coefficients. The scores showed acceptable agreement, but with a slight tendency to higher scores on VAS with the PDA than the paper/pencil version. No significant differences were seen for measures of feasibility ( time to complete, satisfaction score), but 65.5% preferred PDA, 20.7% preferred paper, and 13.8% had no preference.Conclusions: The clinimetric performance of paper/pencil versions of self reported health status measures was similar to an electronic version, using an inexpensive PDA.
