ABSTRACT

We describe the use of tablet computers with ESRI Survey123 for data collection in sociodemographic surveys applied to land use and cover change studies. Based on the administration of 716 questionnaires during the expedition carried out in 2022 in 64 rural communities along the Rio Negro River, in the Brazilian Amazon, we evaluate the advantages of computer-aided personal interviewing (CAPI) instead of paper-and-pencil interviewing (PAPI). The results point to reduced research time and costs, including for training, fieldwork supervision, and data processing. The unit cost of the questionnaire was reduced by an estimated 10%. We observed positive impacts on data quality, contact with communities, and dissemination of geocoded results. We conclude that the approach adopted by us was sufficient for the success of the survey, which indicates that CAPI can be used under unfavorable field conditions (lack of electricity and poor internet connection).

摘要

我们描述了平板电脑与 ESRI Survey123 的使用，用于土地利用和覆盖变化研究的社会人口统计调查中的数据收集。根据 2022 年在巴西亚马逊里奥内格罗河沿岸 64 个农村社区进行的考察期间对 716 份问卷的管理，我们评估了计算机辅助个人访谈 (CAPI) 相对于纸笔访谈的优势（帕皮伊）。结果表明，研究时间和成本减少，包括培训、实地工作监督和数据处理。调查问卷的单位成本估计降低了 10%。我们观察到对数据质量、与社区的联系以及地理编码结果的传播产生的积极影响。我们的结论是，我们采用的方法足以使调查取得成功，
