在资源匮乏的情况下,现有的电子数据采集选择在财务上往往是不可行的,或者难以在外地提供技术支持。为了帮助促进撒哈拉以南非洲的大规模多中心研究,非洲慢性病研究伙伴关系(APCDR)开发了一个开源电子问卷(EQ)。为了评估其相对有效性,我们在南非进行的一项2型糖尿病病例对照研究中,使用了200次随机访谈,将情商与传统的纸笔方法进行了比较。在为期3个月的验证中,与纸笔方法相比,EQ的错误频率较低(EQ,每100个问题有0.17个错误;纸质,每100个问题有0.73个错误;P值≤为0.001),每个正确输入的问题的货币成本更低。我们发现,两种方法的平均访谈时长没有显著差异(情商,5.4分钟;纸质,5.6分钟)。这项验证研究表明,与纸质数据收集方法相比,EQ可能提供更高的准确性、相似的访谈持续时间和更高的成本效益。APCDR EQ软件是免费提供的(https://github.com/apcdr/questionnaire).
Existing electronic data capture options are often financially unfeasible in resource-poor settings or difficult to support technically in the field. To help facilitate large-scale multicenter studies in sub-Saharan Africa, the African Partnership for Chronic Disease Research (APCDR) has developed an open-source electronic questionnaire (EQ). To assess its relative validity, we compared the EQ against traditional pen-and-paper methods using 200 randomized interviews conducted in an ongoing type 2 diabetes case–control study in South Africa. During its 3-month validation, the EQ had a lower frequency of errors (EQ, 0.17 errors per 100 questions; paper, 0.73 errors per 100 questions; P-value ≤0.001), and a lower monetary cost per correctly entered question, compared with the pen-and-paper method. We found no marked difference in the average duration of the interview between methods (EQ, 5.4 minutes; paper, 5.6 minutes). This validation study suggests that the EQ may offer increased accuracy, similar interview duration, and increased cost-effectiveness compared with paper-based data collection methods. The APCDR EQ software is freely available (https://github.com/apcdr/questionnaire).
