Challenges of Developing and Supporting Multimode Survey Instruments

This paper reviews our experiences with multimode survey data collection and the challenges inherent in working with instruments in single and multiple data collection software environments. We will discuss supporting multiple web-based data collection systems in an ever-changing internet environment and the effects they have on data collection. We will also describe the obstacles and solutions involved in coding and maintaining a single Blaise instrument that handles multiple modes of data collection in one central real-time Blaise database.
