目的：手持计算机（个人数字助理，PDA）有可能减少纸质健康研究数据收集的物流负担、成本和错误率，但缺乏适当的软件。本工作描述了PDACT，个人数据收集工具集的开发和评估（www.healthware.org/pdact/index.htm）用于Palm（TM）Pilot手持计算机，用于访谈者管理和应答者管理的数据收集。我们开发了个人数据收集工具包（PDACT）软件，以支持在Windows（TM）应用程序QDS（TM）Design Studio中开发的问卷，将在Palm（TM）Pilot设备上编译和完成，并在几个代表性的实地调查设置中进行评估。结果：该软件已用于七个独立的研究和超过90，000次访谈。经过一天的访谈员培训，在通信基础设施差的农村地区完成了五项访谈员管理的研究。城市中学的学生在15分钟的培训后完成了两项问卷调查，每个手持设备上有多达11种语言的问卷，问题从20到580个不等，完成时间为15到90分钟。在一天内使用了多达200个Palm（TM）Pilot设备，在大约50个设备年的使用中，很少发现技术问题。与基于纸张的收集相比，减少了数据验证和清理时间，发现的错误也更少。PDA数据收集易于使用，并且比纸张更受访问者和受访者（受访者管理和访问者管理）的青睐。数据在收集后数小时内汇编和提供，有助于数据质量保证。虽然硬件增加了第一项研究的设置成本，但此后的累积成本福尔斯下降，并与纸质研究的累积成本（在我们的访谈者管理的研究中为4）趋同。手持数据收集是一种在不同环境下收集健康数据的适当、负担得起和方便的技术。(C)2008爱思唯尔爱尔兰有限公司保留所有权利。
Objective: Handheld computers (personal digital assistant, PDA) have the potential to reduce the logistic burden, cost, and error rate of paper-based health research data collection, but there is a lack of appropriate software. The present work describes the development and evaluation of PDACT, a Personal Data Collection Toolset (www.healthware.org/pdact/index.htm) for the Palm (TM) Pilot handheld computer for interviewer-administered and respondent-administered data collection.Methods: We developed Personal Data Collection Toolkit ( PDACT) software to enable questionnaires developed in QDS (TM) Design Studio, a Windows (TM) application, to be compiled and completed on Palm (TM) Pilot devices and evaluated in several representative field survey settings.Results: The software has been used in seven separate studies and in over 90,000 interviews. Five interviewer-administered studies were completed in rural settings with poor communications infrastructure, following one day of interviewer training. Two respondent-administered questionnaire studies were completed by learners, in urban secondary schools, after 15 min training.Questionnaires were available on each handheld in up to 11 languages, ranged from 20 to 580 questions, and took between 15 and 90 min to complete. Up to 200 Palm (TM) Pilot devices were in use on a single day and, in about 50 device-years of use, very few technical problems were found. Compared with paper-based collection, data validation and cleaning times were reduced, and fewer errors were found.PDA data collection is easy to use and preferred by interviewers and respondents ( both respondent-administered and interviewer-administered) over paper. Data are compiled and available within hours of collection facilitating data quality assurance. Although hardware increases the setup cost of the first study, the cumulative cost falls thereafter, and converges on the cumulative cost of paper-based studies ( four, in the case of our interviewer-administered studies). Handheld data collection is an appropriate, affordable and convenient technology for health data collection, in diverse settings. (C) 2008 Elsevier Ireland Ltd. All rights reserved.
