The use of an electronic audience response system for data collection.
BACKGROUND: Gathering complete and accurate data from community groups, particularly medically underserved populations, is challenging. METHODS: An electronic audience response system (ARS) is a novel method for the efficient collection of data while maintaining participant confidentiality in group settings. RESULTS: Because data are captured electronically, an ARS eliminates the need to transfer data from paper forms, reducing errors and the amount of time required for data management. CONCLUSIONS: ARS is a useful data collection tool that works well with diverse populations and greatly increases data accuracy and completeness while maintaining participant confidentiality.
