Background: RTI International has been developing mobile data capture systems for the past 10 years. In particular, one system provides Field Interviewers with handheld computers and software that manage the capture of interview or inventory data in highly mobile environments, such as household doorway screening and interviewing, and for vendor, intercept, and hospital surveys. This paper describes the current system and its uses for capturing health data. Objective/Purpose: This paper explains the General Survey System (GSS) for handheld computers and discusses study implementation aspects including prevalence surveys with global surveillance relevance. We also describe GSS features and examine GSS use in survey data collection and management. Methods: Based on our work on federally funded projects, RTI International has developed a handheld computer-based system for mobile data collection on handheld computers running Microsoft's Windows Mobile operating system. GSS is a forms-based system that allows users to develop forms and logic to manage and direct the data capture process. It was developed in Microsoft Visual Basic.net and supports • a wide variety of data types, • range and validity checking, • GPS capture, • dynamic sample selection in real time, • complex data capture logic and sequences, • large capacity data storage, • case management and status recording, • a PC-based developers environment for instrument development and data processing, • data file format usable by statistical software, and • internationalization: supports multiple languages and complex Unicode fonts (e.g., Arabic, Mandarin).

Results: The GSS has been in production for over 5 years and continues to evolve based on study requirements. It has been used to conduct over 200,000 interviews in more than 12 countries in 30 languages for more than a dozen study applications. Conclusion: GSS is a proven reliable and flexible survey system that is available for the research community.
