背景。使用7天纸质日记完成克罗恩病活动指数（CDAI）的自我报告项目；然而，也有患者和研究人员/临床医生出现方案偏差的报告。自我报告文献已经证明，这些偏差会通过引入回忆偏差而扭曲收集到的信息，特别是对于疼痛和幸福感等主观测量。目的：本初步研究的目的是评估使用电子日记收集症状自我报告的可行性。方法：16例炎症性肠病患者每天12次完成日记记录，持续3周。日记包括“用户友好”功能，使其更容易融入他们的日常生活。结果：尽管有2个依从性异常值，但总体依从性为88%；当这些异常值被移除后，依从性增加到92%。参与者适当地使用日记功能，每天完成大量的评估。尽管总体依从性在3周的研究期间显著下降，但完成提示的数量并没有随时间发生显著变化。结论：局限性包括样本量小，但尽管如此，本报告支持使用电子日记收集症状信息的可行性。未来的研究需要评估在临床和研究环境中使用电子日记收集CDAI自我报告信息的可能性。
Background. Self-report items from the Crohn's Disease Activity Index (CDAI) are completed using a 7-day paper diary; however, there are reports of protocol deviations by both patients and researchers/clinicians. The self-report literature has demonstrated these deviations can distort the information collected by introducing recall bias, especially for subjective measures like pain and well-being. Purpose: The purpose of this pilot study is to evaluate the feasibility of using an electronic diary to collect symptom self-reports. Methods: Sixteen patients with Inflammatory Bowel Disease completed entries on the diary 12 times per, day for 3 weeks. The diary included "user-friendly" features that made it easier to incorporate into their daily lives. Results: Despite 2 compliance outliers, the overall compliance was 88%; when these outliers were removed compliance increased to 92%. Participants used the diary features appropriately and completed a substantial number of assessments per day. Although overall compliance declined significantly over the 3-week study period, the number of prompts completed did not change significantly over time. Conclusions: Limitations include the small sample size, but despite this limitation this report supports the feasibility of collecting symptom information using an electronic diary. Future studies are needed to evaluate the possibility of using an electronic diary to collect the CDAI self-report information in both clinical and research settings.
