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.
